Description

  The present invention relates to a lamp removal prevention tool, a lighting device, and a method for mounting the lamp removal prevention tool.

  LED (Light Emitting Diode) lamps have lower power consumption and longer life compared to incandescent bulbs and fluorescent lamps. For this reason, LED lamps are spreading as light sources that replace these lamps.

  For example, as a straight tube LED lamp that replaces an existing straight tube fluorescent lamp, a straight tube LED lamp that conforms to the Japan Light Bulb Industry Association standard (JEL801: 2010) is on the market. This straight tube LED lamp employs a base dedicated to the straight tube LED lamp, thereby preventing erroneous insertion and dropping of the lamp and ensuring safety (Non-Patent Document 1).

  On the other hand, there are many needs to replace an LED lamp with an inexpensive and simple modification by using a base or socket of an existing fluorescent lamp. For this reason, straight tube LED lamps that are compatible with conventional fluorescent lamps in the shape of caps and the like are also on the market.

  There are various standards for this straight tube LED lamp. For example, even if the lamps have the same length and the same base shape, there are types such as a lighting circuit built-in type or a lighting circuit non-built-in type, an AC type or a DC type (Non-Patent Document 2).

  Since there are various standards and types of straight tube type LED lamps, there is a risk that a general user will wear an inappropriate lamp when replacing the lamp of the lighting device. As one of the countermeasures, it is conceivable that a general user adopts a structure in which the lamp cannot be easily attached and detached, and a person having specialized knowledge such as a manufacturer of the lighting device replaces the lamp.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lamp attachment / detachment prevention tool in which the attachment / detachment of the lamp cannot be easily performed.

(Embodiment 1)
Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals. The lamp attachment / detachment prevention tool according to the present embodiment is used by being attached to a socket to which an LED lamp is attached. Hereinafter, an embodiment in which an LED lamp having a G13 base is attached to a G13 socket, and the lamp attachment / detachment preventing tool according to the present embodiment is attached to the G13 socket will be described.

  FIG. 1 is a diagram for explaining a configuration of a socket in which a lamp attachment / detachment prevention tool is used. As shown in FIG. 1, the socket 60 to which the lamp attaching / detaching preventing device according to the present embodiment is mounted includes a main body 63 and a rotor 62. Specifically, the socket 60 includes a main body 63 having an opening 64 formed on the front surface, and a rotor 62 that can rotate within the opening 64. The rotor 62 can be inserted with a cap pin of a lamp. An insertion groove 70 is formed, and the main body 63 is formed with a detachment groove 71 which can be attached to and detached from the base pin and communicates with the insertion groove 70 when the rotor 62 is at a predetermined angle.

  The main body 63 has a circular opening 64 formed on the front surface. A rotor 62 and a rotor holding part 61 are arranged in the opening part 64. The rotor holding part 61 is in the vicinity of the center of the opening part 64, and its outer shape is circular. The rotor holding part 61 holds the rotor 62 rotatably on its outer surface.

  The rotor 62 is formed in an annular shape. The inner surface of the ring is slidable with respect to the rotor holding portion 61, and the outer surface of the ring is slidable with respect to the inner wall of the opening 64 of the main body 63.

  The outer diameter of the rotor 62 is slightly larger than the distance between the pair of base pins of the G13 base. Thereby, the rotor 62 can hold | maintain a cap pin, when a pair of cap pin of a lamp | ramp is inserted.

  The rotor 62 has cut-out surfaces 73 and 75 that cut out a part of the outer surface of the ring. When the rotor 62 rotates and is arranged at a location where the straight line Y and the inner wall of the opening 64 intersect as shown in FIG. 1, the notched surfaces 73 and 75 are pressed by elastic means (for example, a spring or a leaf spring). The notch surfaces 73 and 75 function as rotor positioning.

  The rotor 62 and the rotor holding portion 61 are formed with an insertion groove 70 into which a lamp cap pin can be inserted. Since the outer diameter of the rotor 62 is formed to hold the base pin of the G13 base, the LED formed in the same position and size as the base pin of the G13 base is formed in the insertion groove 70 of the present embodiment. A lamp cap pin can be inserted.

  The insertion groove 70 is a linear groove, and is formed so as to divide the rotor 62 into two through the rotation center of the rotor 62. The insertion groove 70 extends from the center of the notch surface 73 toward the center of the facing notch surface 75.

  The groove width of the insertion groove 70 is larger than the thickness of the cap pin, and its length is substantially the same as the outer diameter of the rotor 62. The depth of the insertion groove 70 is substantially the same as the length of the base pin. When the base pin is inserted into the insertion groove 70, the tip of the base pin comes into contact with the bottom of the groove.

  The main body 63 is formed with a detachable groove 71 on the side surface to which the cap pin is detachable. The detaching groove 71 is a linear groove similarly to the insertion groove 70. In order that the cap pin of the lamp can be easily attached and detached, the attaching / detaching groove 71 is widest on the opening side and gradually becomes narrower toward the inner side of the groove. The width on the depth side of the detachable groove 71 is substantially the same as that of the insertion groove 70, and the groove depth of the detachable groove 71 is the same as the depth of the insertion groove 70.

  The detachment groove 71 extends from the main body 63 toward the opening and communicates with the opening 64. Therefore, when the rotor 62 is rotated and arranged at a predetermined angle, that is, when the rotor 62 is rotated so that the insertion groove 70 faces in a direction parallel to the straight line X shown in FIG. The groove 71 communicates with the insertion groove 70.

  An LED lamp is mounted on the socket 60 as follows.

  In a state before the LED lamp is mounted, the socket 60 is rotated such that the rotor 62 faces the insertion groove 70 in a direction parallel to the straight line X shown in FIG. The LED lamp is mounted on the socket 60 in this state.

  First, the base pin of the LED lamp is arranged so as to face the front surface of the socket 60, and the pair of base pins are moved from the attachment / detachment groove 71 on the side surface of the socket toward the back of the groove, that is, in the direction of the arrow of the straight line X shown in FIG. Slide to.

  Since the detachment groove 71 and the insertion groove 70 communicate with each other, the pair of cap pins are inserted into the insertion groove 70. When one of the pair of cap pins reaches the notch surface 75 at the end of the insertion groove 70, the cap pin contacts the wall surface of the opening 64.

  In this state, the LED lamp is rotated around the long axis of the lamp. Specifically, one of the cap pins of the LED lamp is rotated in the direction A shown in FIG.

  When the insertion groove 70 is arranged in parallel with the straight line Y shown in FIG. 1, the notch surfaces 73 and 75 are pressed by an electrode (not shown) biased toward the rotor 62 by the elastic means. For this reason, the rotation of the rotor 62 is temporarily stopped. At this time, the electrode and the cap pin are electrically connected, and the LED lamp is mounted on the socket 60.

  The lamp 60 is attached to the socket 60 in this state, and the lamp removal prevention tool is used.

  FIG. 2 is a diagram for explaining the configuration of the lamp removal prevention tool according to the first embodiment, and FIG. 3 is a diagram for explaining the configuration of the lamp removal prevention tool according to the first embodiment. 3A is a front view, and FIG. 3B is a side view. As shown in FIGS. 2 and 3, the lamp attachment / detachment prevention device 1 according to the present embodiment includes a shielding part 2, support parts 3R and 3L, and insertion parts 4R and 4L. When the lamp attachment / detachment prevention tool 1 is attached to the socket 60, the shielding part 2 closes the opening of the attachment / detachment groove 71 of the socket, the support parts 3R, 3L support the shielding part 2, and the insertion parts 4R, 4L are the rotor 62. And the opening 64.

  The lamp attachment / detachment prevention tool 1 is formed in the form of a single plate that is connected from the end in the order of the insertion portion 4R, the support portion 3R, the shielding portion 2, the support portion 3L, and the insertion portion 4L, and is bent at the connection location. . The length of the side of the shielding portion 2, the support portions 3R and 3L, and the insertion portions 4R and 4L along the direction of alignment (longitudinal direction of the lamp attachment / detachment prevention device 1) is the length, and the direction intersecting the length (the lamp attachment / detachment prevention device 1). The width of the side in the short direction is called the width. In the first embodiment, each part of the lamp attachment / detachment prevention tool 1 is formed to have a uniform width D1.

  The shielding part 2 is formed in a rectangular plate shape. The length A1 of the shielding part 2 is formed to be almost the same as the width of the groove of the socket attaching / detaching groove 71. Thereby, when the lamp attachment / detachment prevention tool 1 is attached to the socket 60, the shielding portion 2 shields the attachment / detachment groove 71 of the socket.

  The width D1 of the shielding part 2 is formed slightly smaller than the depth of the groove of the socket attaching / detaching groove 71. If D1 has such a width, the shielding part 2 shields most of the groove of the attaching / detaching groove 71, which makes it difficult for the user to remove the lamp attaching / detaching preventing tool 1 from the socket. In order to make it difficult to remove the lamp attachment / detachment prevention tool 1 from the socket, the width D1 is preferably formed to have substantially the same length as the depth of the attachment / detachment groove 71.

  Thus, the shielding part 2 is formed in the same shape as the opening formed in the side surface of the main body 63 by the desorption groove 71. Since the opening of the desorption groove 71 is rectangular, the shielding part 2 shown in FIG.

  As shown in FIGS. 2 and 3, the support portions 3 </ b> R and 3 </ b> L are formed on both sides of the surface of the shielding portion 2 so as to intersect the surface of the shielding portion 2 at a predetermined angle. Specifically, the support portions 3R and 3L are substantially perpendicular to the shield portion from both sides of the end portion in the short direction of the shield portion to the same plane as the shield portion (the angle p1 shown in FIG. 3 is approximately 90 degrees). It extends in the direction of bending. The direction in which the support portions 3R and 3L are bent is the same surface side (the lower side in FIG. 3A) with respect to the surface of the shield portion 2, and the shield portion 2 and the support portions 3R and 3L have a U-shaped cross section. There is no. Since the attachment / detachment groove 71 shown in FIG. 1 has substantially parallel walls on both sides on the inner side, the support groove 3R is disposed when the lamp attachment / detachment prevention device 1 is attached to the socket 60 by being arranged at such an angle. , 3L easily adheres to the desorption groove 71.

  As described above, the support portions 3R and 3L are set to have the same angle with respect to the surface of the shielding portion 2 as the angle of the attachment / detachment groove 71 with respect to the side surface of the main body 63 of the socket 60. It is possible to make it adhere to.

  The support portions 3R and 3L are formed in a rectangular plate shape like the shielding portion 2. The length B1 of the support portion 3R is formed longer than the length of the desorption groove 71. Thus, when the lamp attachment / detachment prevention tool 1 is mounted on the socket 60, the support portions 3R, 3L reach the end of the attachment / detachment groove 71 (that is, the portion where the attachment / detachment groove 71 communicates with the insertion groove 70), and the tip thereof Is sandwiched between the rotor 62 and the inner wall of the opening 64 together with the insertion portions 4R and 4L.

  The width D1 of the support portions 3R and 3L is the same as the width D1 of the shielding portion 2. With such a width, the portion of the attachment / detachment groove 71 that comes into contact with the groove increases, so that it is possible to make it difficult for the lamp attachment / detachment prevention tool 1 to be detached from the socket 60 by the frictional force.

  The insertion portions 4R and 4L are formed so as to intersect the surfaces of the support portions 3R and 3L at predetermined angles from the ends of the support portions 3R and 3L, respectively. Specifically, the insertion portions 4R and 4L extend from the ends of the support portions 3R and 3L in a direction that bends in a substantially vertical direction (the angle q1 shown in FIG. 3 is approximately 90 degrees). The directions in which the insertion portions 4R and 4L bend are opposite to each other with respect to the shielding portion 2 (the right or left direction in FIG. 3A).

  The insertion groove 70 shown in FIG. 1 intersects with a groove formed at the end of the gap formed between the rotor 62 and the main body 63, but the insertion parts 4R and 4L are formed to be bent at such an angle. As a result, the distal ends of the insertion portions 4R and 4L are easily caught in the gap. For this reason, when the lamp attachment / detachment prevention tool 1 is attached to the socket 60, the insertion portions 4R and 4L can be easily inserted into the gap.

  The insertion portions 4R and 4L are formed in a rectangular plate shape, like the shielding portion 2 and the support portions 3R and 3L. The lengths C1 of the insertion portions 4R and 4L are formed to be, for example, half the length of the shielding portion 2. One side of the rectangular shape of the insertion portions 4R and 4L is formed to have a length such that a sufficient frictional force is obtained when the insertion portions 4R and 4L are inserted into the gap between the rotor 62 and the main body 63.

  The width D1 of the insertion portions 4R and 4L is the same as that of the shielding portion 2 and the support portions 3R and 3L. If it is such a width | variety, it is the same as support part 3R, 3L that it is possible to make it difficult to remove | deviate.

  The thickness of the lamp attaching / detaching preventing tool 1, that is, the thickness of the shielding portion 2, the supporting portions 3R and 3L, and the inserting portions 4R and 4L is, for example, 0.4 to 0.5 mm. With such a thickness, the cap pin of the LED lamp cannot pass through the attaching / detaching groove 71, and the LED lamp cannot be easily removed from the socket 60 by attaching the lamp attaching / detaching preventing tool 1. Further, with such a thickness, the insertion portions 4R, 4L and the like of the lamp attachment / detachment prevention tool 1 can be inserted between the rotor 62 and the main body 63.

  Specifically, for example, the thickness of the base pin of the LED lamp is the same as the standard of the G13 base (2.29 to 2.67 mm), and the groove width of the attachment / detachment groove 71 (or the insertion groove 70) is 3.0 mm. If the thickness of the lamp attachment / detachment prevention tool 1 is 0.17 to 0.36 mm or more, the two support portions 3R and 3L inserted in the attachment / detachment groove 71 block the attachment / detachment groove 71, and the cap pin is attached to the attachment / detachment groove. It is possible to prevent passage through 71. Since the groove width of the attachment / detachment groove 71 is reduced by the total thickness of the two support portions by mounting the lamp attachment / detachment prevention tool 1, the sum of the diameter of the base pin and the thickness of the two support portions is the groove width of the attachment / detachment groove 71. It needs to be larger.

  The shielding part 2, the support parts 3R and 3L, and the insertion parts 4R and 4L are formed of the same resin material. Since the material is a resin material, for example, even when the opening of the desorption groove 71 and the groove cross-sectional shape at the back thereof are different, the shielding part 2 can be deformed according to the shape. The support portions 3R and 3L can also be deformed according to the shape of the detachment groove 71.

  The deformable material includes a metal material in addition to a resin material. Since the lamp attachment / detachment prevention device 1 is disposed in the vicinity of the base pin or the electrode, when the shielding portion 2 or the like is formed using a metal material, it is formed by taking an insulation measure such as coating the surface thereof with an insulating film. .

  The shielding part 2, the support parts 3R and 3L, and the insertion parts 4R and 4L are preferably formed of an elastic material. For example, when the lamp attachment / detachment prevention device 1 is mounted on the socket 60 and formed in a resin material as in the present embodiment, the support portions 3R and 3L try to return to the original shape in the attachment / detachment groove 71, The portions 3R and 3L can be brought into close contact with the attachment / detachment groove 71.

  The lamp attaching / detaching preventing tool 1 according to the present embodiment is manufactured such that the plate-like member is bent. Specifically, the central part of the rectangular plastic plate is used as the shielding part 2, and the support parts 3R and 3L are formed by folding both sides thereof. The end portions of the formed support portions 3R and 3L are set as insertion portions 4R and 4L, and the boundaries thereof are valley-folded to form the insertion portions 4R and 4L.

  Thus, the structure of the lamp attaching / detaching preventing tool 1 according to the present embodiment is simple. For this reason, the lamp attaching / detaching preventing tool 1 according to the present embodiment can be easily and inexpensively manufactured.

  FIG. 4 is a diagram for explaining a method of using the lamp removal prevention tool according to the first embodiment.

  FIG. 4A shows the socket in a state where the base of the LED lamp is mounted and the LED lamp is rotated and mounted. The lamp attachment / detachment prevention tool 1 is attached to the socket 60 in this state. As shown in FIG. 4A, the lamp removal prevention tool 1 is mounted from the side surface of the socket 60.

  First, as shown in FIG. 4B, the lamp attachment / detachment prevention tool 1 is deformed with the support portion 3 and the insertion portion 4 of the lamp attachment / detachment prevention device 1 interposed therebetween. The interval between one tip of the insertion portion 4 and the other tip is made smaller than the detachment groove 71.

  Next, as shown in FIG. 4C, the insertion portion 4 of the lamp attachment / detachment prevention tool 1 is inserted into the attachment / detachment groove 71 of the socket 60. When the lamp attachment / detachment prevention tool 1 is pushed into the attachment / detachment groove 71, the distal end of the insertion portion 4 reaches a portion where the attachment / detachment groove 71 communicates with the insertion groove 70. Since the distal end of the insertion portion 4 is disposed so as to open outward with respect to the support portion 3, the insertion portion 4 is caught in the gap between the rotor 62 and the main body 63, and the insertion portion 4 is shown in FIG. As described above, the rotor 62 is inserted into the gap between the rotating side surface of the rotor 62 and the opening side surface of the main body 63.

  Finally, as shown in FIG. 4 (E), the lamp attachment / detachment prevention tool 1 is pushed to a position where the shielding part 2 of the lamp attachment / detachment prevention tool 1 covers the opening of the attachment / detachment groove 71. Part of the support portions 3R and 3L and the insertion portions 4R and 4L are inserted into the gap between the rotor 62 and the main body 63.

  When the shield part 2 of the lamp attachment / detachment prevention tool 1 is pushed in until the shield part 2 is disposed inside the opening of the attachment / detachment groove 71, that is, inside the attachment / detachment groove 71 rather than the side surface of the socket 60, It becomes difficult to remove the lamp attachment / detachment prevention tool 1 by hooking.

  Once the lamp removal prevention tool 1 is inserted, the lamp side (socket front side) of the socket 60 is blocked by the lamp cap, and is difficult to remove. In a state in which the lamp attachment / detachment prevention tool 1 is mounted, the base can be rotated in the socket 60, but the attachment / detachment groove 71 is blocked by the lamp attachment / detachment prevention tool 1, so that the base pin is attached to the socket 60. Cannot be removed to the side. If the total thickness of the two support portions 3R, 3L is larger than the gap between the attachment / detachment groove 71 and the attachment pin, the attachment pin cannot be removed from the attachment / detachment groove 71 unless the lamp attachment / detachment prevention tool 1 is removed.

  As described above, the lamp attachment / detachment prevention device 1 according to the present embodiment has a simple structure and is easy to attach. When the lamp attachment / detachment prevention tool 1 according to the present embodiment is mounted on the socket 60, the attachment / detachment of the lamp cannot be easily performed.

  When the lamp attachment / detachment prevention tool 1 is attached to the socket 60, the attachment / detachment of the lamp is performed by removing the socket 60 from the lighting device. Specifically, the lighting device is disassembled with a tool or the like to expose a socket base disposed inside the lighting device. Thereafter, by pressing a release button 65 provided on the socket base, the socket 60 is removed from the lighting device, and the LED lamp is pulled out from the socket 60.

  FIG. 5 is a view for explaining a modification of the lamp attachment / detachment prevention device according to the first embodiment. As shown in FIG. 5, the lamp attaching / detaching preventing device according to Embodiment 1 can be variously modified.

  For example, as shown in FIG. 5A, the shielding part 2 may have a curved surface shape as well as a plate-like planar shape. The shield 2 may be formed in a shape having an arcuate curved surface that matches the outer diameter of the socket 60.

  Further, as shown in FIG. 5B, the shielding portion 2 may be formed in a cubic shape or a rectangular parallelepiped shape, and the support portions 3R and 3L and the insertion portions 4R and 4L may be formed of plate members. At least the insertion portions 4R and 4L are plate-like members among the shielding portion 2, the support portions 3R and 3L, and the insertion portions 4R and 4L so that the insertion portions 4R and 4L can be inserted between the rotor 62 and the main body 63. May be formed.

  As shown in FIG. 5C, the shielding part 2 may be formed to have a different thickness from the support parts 3R, 3L and the insertion parts 4R, 4L. For example, in order for the shielding part 2 to block the desorption groove 71 more completely, the shielding part 2 is formed to be the thickest, and the thickness of the shielding part 2, the support parts 3R and 3L, and the insertion parts 4R and 4L in that order. You may form so that it may become thin.

  As shown in FIG. 5D, the support portions 3 </ b> R and 3 </ b> L may be arranged such that the surfaces thereof form an acute angle with respect to the surface of the shielding portion 2. The angle formed by the surfaces of the support portions 3R and 3L with respect to the surface of the shielding portion 2 (p12 shown in FIG. 5D) is not limited to 90 degrees, and depends on the shape of the attachment / detachment groove 71 of the socket 60 to be attached. Can be changed.

  As shown in FIG. 5 (E), the size of the shielding portion 2 when viewed from the side (D12 shown in FIG. 5 (E)) is the size of the support portions 3R, 3L or the insertion portions 4R, 4L (FIG. 5). The size may be different from D13) shown in (E). When the size of the shielding part 2 when viewed from the side is larger than the size of the support parts 3R, 3L or the insertion parts 4R, 4L (when D12 shown in FIG. 5 (E) is larger than D13), the shielding part 2 side It is possible for the shielding part 2 to block the desorption groove 71 more completely.

(Embodiment 2)
In the lamp attachment / detachment prevention tool 1 according to Embodiment 2, the support portion is formed by two plate-like members.

  FIG. 6 is a diagram for explaining a configuration of a lamp removal prevention tool according to the second embodiment. 6A is a front view, and FIG. 6B is a side view. As shown in FIG. 6, the lamp attachment / detachment prevention tool 1 according to the present embodiment includes a shielding part 2, first support parts 31R and 31L, second support parts 32R and 32L, and insertion parts 41R and 41L. ing. The lamp attachment / detachment prevention tool 1 is connected from the end in the order of the insertion portion 41R, the second support portion 32R, the first support portion 31R, the shielding portion 2, the first support portion 31L, the second support portion 32L, and the insertion portion 41L. , It is formed into a single plate bent at the connection point. The shielding part 2 and the insertion parts 41R and 41L are the same as in the first embodiment, and each part of the lamp attaching / detaching prevention tool 1 is formed to have a uniform width (width D2) as in the first embodiment. Therefore, the first support portions 31R and 31L and the second support portions 32R and 32L will be described.

  The first support portions 31R and 31L extend on both sides of the shielding portion 2 in a direction in which the first supporting portions 31R and 31L are bent at approximately 90 degrees (the angle p2 shown in FIG. 6 is approximately 90 degrees) with respect to the surface of the shielding portion 2. As in the first embodiment, the first support portions 31R and 31L are easily brought into close contact with the attachment / detachment groove 71 by being formed at such an angle.

  The first support portions 31R and 31L are formed in a rectangular plate shape, like the support portions 3R and 3L of the first embodiment.

  The length B20 of the first support portions 31R and 31L is formed to be approximately the same length as the length of the desorption groove 71. The length B20 is preferably equal to or shorter than the length of the desorption groove 71, and more preferably shorter than the length of the desorption groove 71. As a result, when the lamp attachment / detachment prevention device 1 is attached to the socket 60, the tips of the first support portions 31R and 31L reach the end portion of the attachment / detachment groove 71, and the shielding portion 2 is attached / detached more than the socket 60 surface or the socket surface. Arranged inside the groove 71. For this reason, it becomes difficult to remove the lamp attachment / detachment prevention tool 1 by hooking the shielding portion 2 with, for example, a nail, and the attachment / detachment of the lamp cannot be easily performed.

  The width D2 of the first support portions 31R and 31L is the same length as in the first embodiment. In order to make it difficult for the lamp attachment / detachment prevention tool 1 to be detached from the socket 60 due to the frictional force, such a width is formed.

  The second support portions 32R and 32L are bent from the ends of the first support portions 31R and 31L so as to form an obtuse angle (angle q20 shown in FIG. 6) with respect to the surfaces of the first support portions 31R and 31L. Are arranged. Further, at the end portions of the second support portions 32R and 32L, the insertion portions 41R and 41L have a larger obtuse angle with respect to the surfaces of the second support portions 32R and 32L (angles q21 and q21> q20 shown in FIG. 6). Are arranged so as to be bent.

  As described above, the lamp attachment / detachment prevention device 1 includes two plate-shaped members, that is, a plate-shaped member including the first support portion 31R, the second support portion 32R, and the insertion portion 41R, the first support portion 31L, and the first support portion 31L. 2 A plate-like member constituted by the support portion 32L and the insertion portion 41L is formed so as to gradually open outward from the center of the shielding portion 2 toward the end portion. For this reason, when the lamp attachment / detachment prevention tool 1 is mounted on the socket 60, the insertion portions 41R and 41L can be inserted into the gap between the rotor 62 and the main body 63 as compared with the case of the first embodiment. It is easier.

  The length B21 of the second support portions 32R and 32L is such a length that sufficient frictional force is obtained when the first support portions 31R and 31L are inserted into the gap between the rotor 62 and the main body 63. It is formed. For example, it is formed in a length of 3 to 5 mm.

  The width D2 of the second support portions 32R and 32L is the same as that of the first support portions 31R and 31L.

  As in the first embodiment, the thickness of the lamp removal prevention tool 1, that is, the thickness of the shielding portion 2, the first support portions 31R and 31L, the second support portions 32R and 32L, and the insertion portions 41R and 41L is, for example, 0. 4 to 0.5 mm. With such a thickness, the LED lamp cannot be easily removed from the socket 60, and a part of the lamp removal prevention tool 1 can be inserted between the rotor 62 and the main body 63. Same as 1.

  The lamp removal prevention tool 1 is made of an elastic resin material (plastic). For this reason, the first support portions 31 </ b> R and 31 </ b> L are elastically deformed according to the shape of the desorption groove 71 and are in close contact with the desorption groove 71.

  The lamp attaching / detaching preventing tool 1 according to the present embodiment is manufactured so that the plate-like member is bent as in the first embodiment. For this reason, also in this embodiment, the structure is simple, and it can be manufactured easily and inexpensively.

  FIG. 7 is a diagram for explaining a method of using the lamp removal prevention tool according to the second embodiment.

  As shown in FIG. 7A, the lamp attachment / detachment prevention tool 1 is mounted from the side of the socket 60 as in the first embodiment. When the LED lamp cap is attached to the socket 60 and the LED lamp is rotated and attached, the attachment / detachment prevention tool 1 is attached as in the first embodiment.

  First, as shown in FIG. 7B, the lamp attachment / detachment prevention tool 1 is deformed with the first support portion 31, the second support portion 32, and the insertion portion 41 of the lamp attachment / detachment prevention device 1 interposed therebetween. It is the same as in the first embodiment that the insertion portion 41 is deformed so that the distance between one tip and the other tip is smaller than the detachment groove 71.

  Next, as shown in FIG. 7C, the insertion portion 41 of the lamp attachment / detachment prevention tool 1 is inserted into the attachment / detachment groove 71 of the socket 60. When the lamp attachment / detachment prevention tool 1 is pushed into the attachment / detachment groove 71, the distal end of the insertion portion 41 reaches a portion where the attachment / detachment groove 71 communicates with the insertion groove 70, and is caught in a gap between the rotor 62 and the main body 63. The insertion portion 41 is inserted into the gap between the rotor 62 and the main body 63 as shown in FIG.

  Finally, as shown in FIG. 7 (E), the lamp attachment / detachment preventive tool up to a position where the end of the first support portion 31 of the lamp attachment / detachment preventive tool 1 is disposed at a portion of the attachment / detachment groove 71 that communicates with the insertion groove 70. Push 1 in. Accordingly, the second support portion 32 and the insertion portion 41 are inserted into the gap between the rotating side surface of the rotor 62 and the opening side surface of the main body 63.

  In this state, since the length of the first support portion 31 is the same as or shorter than the length of the detachable groove 71, the shielding portion 2 is disposed in the vicinity of the opening of the detachable groove 71 or inside thereof. If it arrange | positions in this way, it will become difficult to remove the lamp | ramp attachment / detachment prevention tool 1, for example by hooking with a nail | claw.

  As in the first embodiment, once the lamp removal prevention tool 1 is inserted, the lamp side (socket front side) of the socket 60 is blocked by the lamp cap, so that it is difficult to remove. Also in this embodiment, if the total thickness of the two first support portions 31R and 31L is larger than the gap between the attachment / detachment groove 71 and the attachment pin, the attachment / detachment groove 71 is attached to the attachment / detachment groove 71 unless the lamp attachment / detachment prevention device 1 is removed. Can not be removed from.

  Note that the lamp is attached and detached by removing the socket 60 from the lighting device, as in the first embodiment.

  As in the first embodiment, the lamp attachment / detachment preventing tool 1 according to the present embodiment has a simple structure and is easy to mount. In addition, by using the lamp attachment / detachment prevention tool 1 according to the present embodiment, it is possible to prevent the lamp from being easily attached / detached.

  FIG. 8 is a diagram for explaining a modification of the lamp attachment / detachment preventer according to the second embodiment. As shown in FIG. 8, the lamp attachment / detachment preventing tool according to Embodiment 2 can be variously modified.

  For example, similarly to the first embodiment, the shielding portion 2 may be formed in a cubic shape or a rectangular parallelepiped shape, and the first support portion 31, the second support portion 32, and the insertion portion 41 may be formed of a plate-like member (see FIG. 8 (A)).

  Moreover, the shielding part 2 may be formed in the thickness from which the 1st support part 31, the 2nd support part 32, and the insertion part 41 differ similarly to Embodiment 1 (refer FIG.8 (B)). The length of the side where the second support part 32 is in contact with the insertion part 41 may be different from that of the insertion part 41 (see FIG. 8C).

  FIG. 9 is a diagram for explaining another method of using the lamp removal prevention tool according to the embodiment. In the first and second embodiments, the insertion portion and the support portion of the lamp attachment / detachment prevention tool are inserted between the side surface of the main body opening and the rotation side surface of the rotor. On the other hand, as shown in FIG. 9, the insertion part and the support part of the lamp attachment / detachment prevention device according to the present embodiment are an LED lamp provided with a base pin between the front bottom surface of the main body opening and the rotor, and a base pin. A configuration in which a lamp attachment / detachment prevention tool is inserted between the face of the base and the rotor may be employed.

  In this case, the length of the shielding portion 2 (A1 shown in FIG. 3) is set to fit into the depth of the desorption groove 71, and the width of the shielding portion 2 (D1 shown in FIG. 3) is the width of the removal groove 71. The size fits exactly. When the lamp attachment / detachment prevention tool 1 is inserted after the LED lamp is attached to the socket 60, it is difficult to take out the lamp attachment / detachment prevention device 1 as in the first embodiment. If the thickness of the shielding portion 2 is set so as not to enter between the rotating side surface of the rotor 62 and the side surface of the main body opening, the shielding portion 2 remains in the attachment / detachment groove 71 even when the rotor 62 is rotated. It remains. Therefore, since at least the insertion part 32 on the base side is between the attachment / detachment groove 71 and the insertion groove 71, the base pin and the insertion part interfere with each other, and the base pin cannot be aligned with the position of the attachment / detachment groove 71. As a result, the LED lamp cannot be removed from the socket 60. Even in this configuration, the attachment / detachment groove 71 is blocked by the lamp attachment / detachment prevention tool 1, so that it is difficult to remove the cap pin to the side of the socket 60. If the lamp attachment / detachment prevention device 1 is formed of an elastic body in the shape as shown in FIG. 6 or FIG. 8, the bottom surface of the main body opening and the base are pressed with elasticity, so that even if the attachment / detachment groove 71 faces downward, The lamp attachment / detachment prevention tool 1 does not fall off.

(Embodiment 3)
The lamp attaching / detaching preventing tool 1 according to the third embodiment is formed such that the insertion portion 4 can be hooked on the side surface of the opening of the main body 63 and the handle 2 is provided with the handle 5.

  10 and 11 are diagrams for explaining the configuration of the lamp attachment / detachment preventing tool according to the third embodiment. 10 is a perspective view, FIG. 11A is a plan view, FIG. 11B is a left side view, FIG. 11C is a front view, FIG. 11D is a right side view, and FIG. As shown in FIGS. 10 and 11, the lamp attachment / detachment prevention device 1 according to Embodiment 3 includes a handle 5, a shielding part 2, first support parts 31 </ b> R and 31 </ b> L, and second support parts 32 </ b> R and 32 </ b> L. Insertion parts 41R and 41L are provided. The lamp attachment / detachment prevention tool 1 is connected from the end in the order of the insertion portion 41R, the second support portion 32R, the first support portion 31R, the shielding portion 2, the first support portion 31L, the second support portion 32L, and the insertion portion 41L. The handle 5 is branched at the shielding part 2 on the way. Since the shape of the shielding part 2 is substantially the same as in the first and second embodiments, other configurations will be described below.

  The handle 5 extends from the shielding part 2 in a substantially vertical direction (opposite to the X arrow shown in FIG. 10) from a surface opposite to the direction in which the first support parts 31R and 31L are bent and extended. The handle 5 is a portion for holding the lamp attachment / detachment prevention tool 1 by an operator when inserting the insertion portions 41 </ b> R and 41 </ b> L into the attachment / detachment groove 71 of the socket 60. The handle 5 is formed in a plate shape and a rectangular shape so that an operator can easily pick it up.

  The first support portions 31R and 31L are bent and extended at an acute angle (angle p3 shown in FIG. 11C) with respect to the surface of the shielding portion 2 so as to be in close contact with the desorption groove 71. Its shape is an inverted L shape, and is composed of base portions 312R and 312L and protruding portions 311R and 311L.

  The base portions 312R and 312L and the protruding portions 311R and 311L are connected in this order from the shielding portion 2 side in the order of the base portion 312R and the protruding portion 311R (or the base portion 312L and the protruding portion 311L). The base portions 312R and 312L are formed in a rectangular shape having the same width as the shielding portion 2, and the protruding portions 311R and 311L are formed in a rectangular shape having a width less than half the width of the shielding portion 2 (D3a shown in FIG. 11). Yes. The protruding portions 311R and 311L are formed so as to protrude from the ends of the base portions 312R and 312L.

  As shown in FIGS. 11B and 11D, the protruding portions 311R and 311L are alternately arranged when viewed from the side. That is, the protruding portions 311R and 311L are arranged with a width D3b apart in the positional relationship in the side surface direction, and the protruding portions 311R and 311L do not overlap each other. For this reason, when the lamp attachment / detachment prevention tool 1 is inserted into the attachment / detachment groove 71 of the socket 60, a force is applied in a direction substantially perpendicular to the surfaces of the first support portions 31R and 31L (that is, inward from both sides). Even so, the protruding portions 311R and 311L do not interfere with each other at their tips. Thereby, the lamp attachment / detachment prevention tool 1 can be deformed more greatly, and can be easily inserted into the attachment / detachment groove 71.

  The second support portions 32R and 32L and the insertion portions 41R and 41L are arranged in the order of the second support portion 32R and the insertion portion 41R (or the second support portion 32L and the insertion portion 41L) from the end of the protruding portion 311R (or 311L). The width is the same as that of the protruding portion 311R (or 311L). For this reason, the second support portions 32R and 32L and the insertion portions 41R and 41L are similar to the protruding portions 311R and 311L, the structures on both sides of the shielding portion 2 do not interfere with each other, and the attachment / detachment of the lamp attachment / detachment prevention device 1 is performed. Insertion into the groove 71 is easy.

  The second support portions 32R and 32L and the insertion portions 41R and 41L are respectively at a predetermined angle (angle q30 shown in FIG. 11C) with respect to the surfaces of the protruding portions 311R and 311L, and the surfaces of the second support portions 32R and 32L. Are bent so as to form a predetermined angle (angle q31 shown in FIG. 11).

  Since the lamp attachment / detachment prevention tool 1 is formed in the above-described shape, the lamp attachment / detachment prevention tool 1 can close the attachment / detachment groove 71 and be hooked on the side surface of the opening of the main body 63 when attached to the socket 60. is there. Hereinafter, the relationship between the shape of the lamp attaching / detaching preventing tool 1 and the shape of the socket 60 will be described in detail.

  FIG. 12 is a cross-sectional view of the lamp attaching / detaching preventing tool and the socket in a state where the lamp attaching / detaching preventing tool according to Embodiment 3 is mounted on the socket. As shown in FIG. 12, the main body 63 of the socket 60 is composed of first wall portions 631R and 631L and second wall portions 711R and 711L. The first wall portions 631R and 631L form the outer shape of the main body 63. The second wall portions 711 </ b> R and 711 </ b> L are portions where the first wall portions 631 </ b> R and 631 </ b> L are bent toward the inner side of the main body 63, and the inner wall forms a desorption groove 71.

  On the other hand, the width of the shielding part 2 of the lamp attaching / detaching preventing tool 1 (A3 shown in FIG. 12) is substantially the same as the distance between the inner walls of the second wall parts 711R and 711L (that is, the groove width of the attaching / detaching groove 71). Furthermore, the depth of the shielding part 2 (D3 shown in FIG. 11) is formed to be approximately the same as the height of the second wall parts 711R and 711L (that is, the groove depth of the detaching groove 71). Further, the length of the first support portions 31R and 31L (B30 shown in FIG. 12) is formed to be approximately the same as the length of the second wall portions 711R and 711L (the length of the detaching groove 71).

  For this reason, when the lamp attachment / detachment prevention tool 1 is attached to the socket 60, the first support portions 31R, 31L are disposed so as to contact the inner walls of the second wall portions 711R, 711L, and the attachment / detachment groove of the socket 60 is covered by the shielding portion 2. 71 can be shielded.

  In the socket 60, the end surfaces of the second wall portions 711 </ b> R and 711 </ b> L are configured as surfaces that intersect the inner wall substantially perpendicularly, and this surface forms the opening side surface of the main body 63. The opening side surface of the main body 63 faces the rotation side surface of the rotor 62 with a predetermined distance.

  On the other hand, in the lamp attachment / detachment prevention tool 1, the angle formed by the first support portions 31R, 31L and the second support portions 32R, 32L (angle q30 shown in FIG. 11C) is the second wall portion 711R, It is formed at substantially the same angle (a slightly larger angle) as the angle formed by the end surface of 711L and the inner wall. And the thickness (B35, B36 shown in FIG. 12) of 2nd support part 32R, 32L and insertion part 41R, 41L is the distance between the end surface of 2nd wall part 711R, 711L and the rotation side surface of the rotor 62. And are approximately the same size.

  For this reason, when the lamp attachment / detachment prevention tool 1 is mounted on the socket 60, the second support portions 32R, 32L and the insertion portions 41R, 41L are connected to the end surfaces of the second wall portions 711R, 711L and the rotation side surfaces of the rotor 62. It is possible to insert the second support portions 32R and 32L so as to contact the end surfaces of the second wall portions 711R and 711L.

  In the socket 60, the end surfaces of the second wall portions 711R and 711L intersect the outer wall substantially perpendicularly. The width of the end surface (that is, the thickness of the second wall surface) is formed to a width T.

  On the other hand, the length of the second support portions 32R and 32L (B31 shown in FIG. 12) is formed to be approximately the same as the width (width T) of the end surfaces of the second wall portions 711R and 711L, and at the tip thereof. The insertion portions 41R and 41L are bent at a predetermined angle (angle q31 shown in FIG. 11C). This predetermined angle is substantially the same angle (a slightly larger angle) as the angle formed between the outer wall and the end face of the second wall portions 711R and 711L.

  Since the second support portions 32R and 32L and the insertion portions 41R and 41L are made of an elastically deformable material, even if they are deformed when mounted on the lamp attachment / detachment prevention tool 1, they are then bent at this predetermined angle. Return to state. For this reason, the insertion parts 41R and 41L face the outer walls of the second wall parts 711R and 711L and are hooked on the outer walls of the second wall parts 711R and 711L in a state where the lamp attachment / detachment prevention tool 1 is mounted on the socket 60. Is possible.

  In the case of the lamp attaching / detaching preventing tool 1 according to Embodiments 1 and 2, when the rotor 62 rotates, the insertion portions 4R and 4L (or 41R and 41L) may move together with the rotor 62 and shift their positions. On the other hand, in the lamp attaching / detaching preventing tool 1 according to the third embodiment, even when the rotor 62 rotates, the insertion portions 41R and 41L are hooked on the outer walls of the second wall portions 711R and 711L, and the first support portion 31R. , 31L and the insertion portions 41R, 41L sandwich the second wall portions 711R, 711L from both sides. For this reason, the position shift of the lamp removal prevention tool 1 is prevented.

  The lamp removal prevention tool 1 according to the present embodiment is manufactured by, for example, injection molding. The material is, for example, nylon resin. Since the structure of the lamp removal prevention tool 1 is relatively simple, it can be manufactured relatively easily and inexpensively.

  FIG. 13 is a diagram for explaining a method of using the lamp removal prevention tool according to the third embodiment.

  As shown in FIG. 13 (A), the lamp attaching / detaching preventing tool 1 is mounted from the side of the socket 60 as in the first and second embodiments. When the base of the LED lamp is mounted on the socket 60 and the LED lamp is rotated and mounted, the lamp removal prevention tool 1 is mounted.

  First, as shown in FIG. 13 (B), either one of the insertion portions 41 of the lamp attachment / detachment prevention tool 1 is inserted into the attachment / detachment groove 71 and pressed against the inner wall of the attachment / detachment groove 71 using the handle 5 to thereby prevent the lamp attachment / detachment prevention tool 1. Deform. The lamp attachment / detachment prevention tool 1 is deformed until the tips of the two insertion portions 41 enter the attachment / detachment groove 71. At this time, since the portions on the front end side with respect to the protruding portion are alternately arranged, it is possible to deform the lamp attaching / detaching preventing tool 1 to a smaller size.

  Next, as shown in FIG. 13C, the insertion portion 41 of the lamp attachment / detachment prevention tool 1 is inserted into the attachment / detachment groove 71 of the socket 60. When the lamp attachment / detachment prevention tool 1 is pushed into the attachment / detachment groove 71 using the handle 5, the distal end of the insertion portion 41 has a gap between the rotor 62 and the main body 63 (that is, the second wall portion 711R, 711L and the rotation side surface of the rotor 62). In this state, as illustrated in FIG. 13D, the insertion portion 41 is inserted into the gap between the rotor 62 and the main body 63 using the handle 5.

  Finally, as shown in FIG. 13 (E), the lamp attachment / detachment prevention tool 1 until the end portion of the first support portion 31 of the lamp attachment / detachment prevention device 1 is disposed at a portion of the attachment / detachment groove 71 that communicates with the insertion groove 70. Push in. Accordingly, as shown in FIG. 12, the second support portions 32R and 32L come to face the end surfaces of the second wall portions 711R and 711L, and the insertion portions 41R and 41L at the end portions thereof are the second wall portion 711R. , Opposite to the outer wall of 711L.

  Thus, since the lamp attachment / detachment preventing tool 1 according to the present embodiment includes the handle 5, it can be easily mounted.

  As in the first and second embodiments, once the lamp removal prevention tool 1 is inserted into the socket 60, it is difficult to remove the lamp 60 because the lamp side of the socket 60 is blocked by the lamp cap. If the total thickness of the two first support portions 31R and 31L is larger than the gap between the attachment / detachment groove 71 and the attachment pin, the attachment pin cannot be removed from the attachment / detachment groove 71 unless the lamp attachment / detachment prevention tool 1 is removed.

  As described above, it is possible to prevent the lamp from being easily attached / detached by using the lamp attaching / detaching preventing tool 1. Further, as described above, even if the rotor 62 rotates, a part of the lamp removal prevention tool 1 does not move together with the rotor 62. For this reason, the rotation of the rotor 62 prevents the lamp removal prevention tool 1 from being easily removed.

  In addition, the attachment / detachment of the lamp is performed by removing the socket 60 from the lighting device as in the first and second embodiments. The attachment / detachment of the lamp removal prevention tool 1 is performed by sliding the socket 60 to the lamp side after the attachment / detachment of the lamp.

  FIG. 14 is a diagram for explaining a modification of the lamp attachment / detachment preventer according to the third embodiment. As shown in FIG. 14, the lamp attaching / detaching preventing tool according to Embodiment 3 can be variously modified.

  For example, as in Embodiments 1 and 2, the pattern 5 may not be provided (see FIG. 14A). Even in such a configuration, it is possible to prevent the lamp from being attached / detached, and it is possible to prevent the lamp attaching / detaching preventing tool 1 from moving due to the rotation of the rotor 62. The handle 5 is provided for the convenience of the work of mounting the lamp attachment / detachment prevention tool 1 and is an optional component. The shape, size, etc. are not particularly limited.

  For example, the handle 5 may have a cut portion 51. The cut portion 51 may be formed at a connection portion with the shielding portion 2 so that the handle 5 can be cut by the cut portion 51 (see FIG. 14B). For example, the cut portion 51 is formed to a depth that allows the operator to tear off. After the lamp attachment / detachment prevention tool 1 is mounted on the socket 60, the handle 5 is cut by the notch 51, so that the handle 5 does not protrude from the socket 60 and the appearance can be improved.

  The handle 5 is applicable to the first and second embodiments in addition to the third embodiment. Also in these forms, by providing the handle 5, when the lamp attaching / detaching preventing tool 1 is inserted into the attaching / detaching groove 71 of the socket 60, workability is improved.

  In the third embodiment, similarly to the first and second embodiments, the protruding portions 311R and 311L of the first support portions 31R and 31L may not be alternately arranged. For example, the first support portions 31R and 31L, the second support portions 32R and 32L, and the insertion portions 41R and 41L are formed with the same width as the shielding portion 2, and are formed so as to overlap each other when viewed from the side. It is also possible (see FIG. 14C). Even in such a configuration, it is possible to prevent the lamp from being attached / detached and to prevent the lamp attaching / detaching preventing tool 1 from being moved by the rotation of the rotor 62. The protruding portions 311R and 311L are provided so as to be easily inserted into the attachment / detachment groove 71, and are optional components. It is sufficient if the operator can pinch the lamp attachment / detachment prevention tool 1 by pinching, and the shape and size thereof are not particularly limited.

  For example, the first support portions 31R and 31L themselves may be alternately arranged in the lateral direction, and the width of the first support portions 31R and 31L is not more than half the width of the shielding portion 2. The width may be formed (see FIG. 14D).

  Such a form is also applicable to the first and second embodiments. For example, in the first embodiment, the left and right support portions 3R and 3L and the insertion portions 4R and 4L may be alternately arranged with the shielding portion 2 interposed therebetween. In this case, the support portions 3R and 3L and the insertion portions 4R and 4L may be formed to have a width equal to or less than half the width of the shielding portion 2.

  In Embodiment 3, although the length (B30 shown in FIG. 11) of 1st support part 31R, 31L demonstrated the form which is substantially the same magnitude | size as the removal groove | channel 71 groove length, 1st support part 31R, 31L It is not limited to this. For example, the length of the first support portions 31R and 31L may be shorter than the length of the desorption groove 71. Since the third embodiment includes the handle 5, it can be inserted to the depth of the detaching groove 71, and the first support portions 31R and 31L can be mounted on the socket 60.

  The lengths (B31 shown in FIG. 11) of the second support portions 32R and 32L are not limited to the same size as the end surfaces of the second wall portions 711R and 711L. For example, the length of the second support portions 32R and 32L may be larger than the width of the end surfaces of the second wall portions 711R and 711L. Even in such a length, the insertion portions 41R and 41L and the first support portions 31R and 31L sandwich the second wall portions 711R and 711L at both ends of the second support portions 32R and 32L, and the rotor 62 has a predetermined amount or more. It is possible to prevent rotation.

  Further, the angle formed by the first support portions 31R, 31L and the second support portions 32R, 32L (the angle q30 shown in FIG. 11C) is formed by the inner walls and end surfaces of the second wall portions 711R, 711L. The angle is not limited to substantially the same angle. For example, when the lengths of the second support portions 32R and 32L are larger than the widths of the end surfaces of the second wall portions 711R and 711L, they may be smaller than the angle formed by the inner walls and the end surfaces of the second wall portions 711R and 711L. Good.

  The same applies to the angle formed by the second support portions 32R, 32L and the insertion portions 41R, 41L (the angle q31 shown in FIG. 11C). For example, when the length of the second support portions 32R and 32L is larger than the width of the end surfaces of the second wall portions 711R and 711L, the angle formed by the second support portions 32R and 32L and the insertion portions 41R and 41L is the second The angle may be smaller than the angle formed by the outer wall and the end face of the walls 711R, 711L.

  In Embodiment 3, although the 1st support part 31R, 31L demonstrated the form bent at the acute angle (angle p3 shown in FIG.11 (C)) with respect to the surface of the shielding part 2, 1st support part 31R, The angle formed by 31L and the surface of the shielding part 2 is not limited to this angle. If the angle formed by the surfaces of the first support portions 31R and 31L and the shielding portion 2 is an acute angle, the gap between the rotor 62 and the main body 63 is reduced when the attachment / detachment groove 71 becomes narrower toward the back. 2 Even if the thickness is larger than the thickness of the support portions 32R, 32L, the lamp attachment / detachment prevention tool 1 does not fall into the interior of the attachment / detachment groove 71. For example, workability is good when the rotor 62 has an elliptical cross section. However, this is an optional element in the present invention because it is for convenience of work. The angle formed by the surfaces of the first support portions 31R and 31L and the shielding portion 2 may be, for example, a substantially right angle or an obtuse angle.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, in the above embodiment, a socket corresponding to an LED lamp having a base pin of the same standard as the G13 base has been described as an example, but it is apparent that the socket can be applied to other rotary sockets. For example, the present invention can be applied to an LED lamp having the same base pin as G5, R17d, Rx17d, etc., which are fluorescent lamp standards.

  Moreover, although the LED lamp was demonstrated to the example in the above form, it is applicable not only to an LED lamp but to the lamp | ramp and socket with which the removal | desorption prevention of a lamp is desired.

  Moreover, although the example where each part of the shielding part 2, support part 3R, 3L, and insertion part 4R, 4L was formed integrally was demonstrated, these may be formed separately and joined.

  Moreover, although the shielding part 2 demonstrated the example which is planar shape and curved surface shape, each part of support part 3R, 3L and insertion part 4R, 4L can be inserted in the attachment / detachment groove | channel 71 of a lamp | ramp, and the rotor 62 and the main body 63 As long as it can be inserted into the gap between the two, it is not limited to a planar shape. Each part of the support parts 3R and 3L and the insertion parts 4R and 4L may have a curved surface shape like the shielding part 2.
