  Examples of the present invention will be described below. The relationship between the embodiments and the claims is as follows. The first embodiment mainly relates to claims 1, 2, 3, 4, 7, etc., and the second embodiment mainly relates to claims 5, 6, etc. In addition, this invention is not limited to this Example at all, and can be implemented in various modes without departing from the gist thereof.

  <Overview>

  The holder for a straight tube type LED lamp of this embodiment is a holder for a straight tube type LED lamp configured not to receive power supply from a support pin that can be attached to a socket of a straight tube type fluorescent lamp. A straight tube type LED lamp end portion is held, a holding portion that does not have a power supply function with respect to the power interface, and a fixing portion for fixing the holding portion to the outside. Further, the present embodiment includes an illumination device including the above-described straight tube type LED lamp holder and the straight tube type LED lamp to which the holder is attached.

  <Configuration>

    (Lighting devices, general holders for straight tube LED lamps)

  FIG. 1 is a diagram illustrating an example of the shape of a straight tube type LED lamp holder according to the present embodiment. FIG. 1A shows a straight tube type LED lamp holder 0100 in a perspective view together with a part of the straight tube type LED lamp 0130 attached to the holder. The apparatus is attached to the ceiling 0140 (hereinafter, the straight tube type LED lamp holder may be simply referred to as “holder” and the straight tube type LED lamp may be simply referred to as “LED lamp”). FIG. 1B shows the holder and the LED lamp separated (the LED lamp is mounted in the direction of arrow a).

    (Straight tube type LED lamp)

  As shown in FIG. 1 (b), the straight tube type LED lamp constituting the illumination device of the present embodiment, that is, the straight tube type LED lamp to which the holder of the present embodiment is attached is a straight tube type fluorescent lamp. A support pin 0131 that can be attached to the socket, an end cap 0132 that hangs the support pin, and a power interface 0133 are provided. The feature of this LED lamp is that it is supplied with electric power through a power interface rather than being supplied with electric power through a support pin. A specific example of the power interface is a connector provided on the end cap. The power interface shown in this figure is also such an example, and the LED lamp is configured to obtain power supply via a connector connected to an external power line 0141. Alternatively, although different from the example in the figure, the power interface may be composed of a power line connected to the end cap and a connector connected to the end of the power interface. For example, it is configured to obtain power supply by connecting the connector of the power interface to an external connector connected to the tip of an external power line.

  The straight tube type LED lamp has the same shape as the conventional straight tube fluorescent lamp (except that it has a power interface), and can be directly attached to an existing straight tube type fluorescent lamp. included. Here, the conventional straight tube fluorescent lamp is a straight tube fluorescent lamp specified in 2.3.1 “List of data sheets” of JISC7617-2 “Straight tube fluorescent lamp-Part 2: Performance specification”. Say. However, as described above, power is not supplied via the support pin, and the support pin only serves as a support for the lamp to be held by the lamp. Or the straight tube | pipe type LED lamp used as the attachment object of the holder of a present Example may have an original specification different from the conventional straight tube | pipe fluorescent lamp.

  Next, a straight tube type LED lamp holder will be described. The straight tube type LED lamp holder 0100 has a holding part 0110 and a fixing part 0120. Although various types of LED lamps can be used, the example shown in FIG. 1 is used by attaching to one surface of an indoor such as a ceiling, wall, or floor or one surface of an article (such as a storage case) placed indoors. (Hereinafter referred to as “ceiling installation type”). Below, the basic structure of a holder and the attachment procedure of the LED lamp to a holder are demonstrated using the example of a ceiling installation type first. Thereafter, other usage forms will be described.

    (Holding part)

  The “holding portion” is for holding the end portion of the straight tube type LED lamp. In FIG. 1B, the hatched portion is the holding portion 0110 (note that the portion indicated by dots is the fixed portion 0120 as will be described later). “Holding” widely includes an operation of keeping the LED lamp in a certain state. 1 shows that the cylindrical holding portion having an insertion opening (not shown in the figure) for inserting the end portion of the LED lamp on the LED lamp side (right side of the drawing) has the same shape, not shown. The other holding part of the LED lamp is held in a state where the LED lamp is sandwiched from both sides. A form that is suspended and held is also included in the “holding” in the present invention.

  The LED lamp end portion held by the holding portion includes a support pin and an end cap. As a specific mode of holding in the present embodiment, for example, as shown in FIG. 1A, an end cap and a support pin provided at an end portion of the LED lamp are inserted into a cylindrical portion of the holding portion. The case where it hold | maintains directly with a holding | maintenance part in the state which exists is mentioned. In addition, as will be described later, only the support pin is inserted into the cylindrical portion of the holding portion, and the end face of the end cap is held in a state of being in direct contact with the end face of the end cap contact portion that is a component of the holding portion. This is also included in “holding” in this embodiment. Furthermore, in addition to the support pin and the end cap, a part of the LED lamp tube that is directly held in a state where it is inserted into the cylindrical portion of the holding part is also referred to as “holding” in this embodiment. included.

  As a specific configuration of the holding portion for keeping the LED lamp in a certain state, for example, a coil spring is provided in a cylinder of the holding portion of the holder arranged at both ends of the LED lamp, and the LED lamp is directed from both sides toward the LED lamp. It is conceivable to hold the LED lamp so as to be sandwiched by the urging force. Details will be described later.

  In addition, although the holding part demonstrated in the above the example which has a substantially cylindrical shape, there is no limitation in particular in the shape of a holder. For example, the holder may have a substantially elliptical column shape, a substantially prismatic shape, or the like. In short, any holder having a space in which the end of the LED lamp can be inserted and held (the same applies to the following). Is).

    (Fixed part)

  The “fixing part” is for fixing the holding part to the outside. As the “outside” to be fixed, a ceiling, a wall, a floor and the like can be considered. “Fixing” includes not only screwing or bonding with an adhesive, but also those that are simply placed on the floor or the like and hooked onto a chain or the like suspended from the ceiling or the like. In the example of FIG. 1, a substantially elliptical plate-like portion to be attached to the ceiling and a columnar portion connecting the plate-like portion and the holding portion constitute a fixing portion, and the fixing portion screws the plate-like portion with screws. It is fixed to the ceiling.

    (Structure of holder for holding LED lamp)

  FIG. 2 is a diagram showing an example of the structure of a straight tube type LED lamp holder according to the present embodiment. The holder corresponding to the ceiling-mounted type similar to that shown in FIG. It is the perspective view seen from the side which attaches an LED lamp. As shown in FIG. 2 (a), the holding part 0210 of the holder 0200 in this figure has a cylindrical shape having an insertion port 0211 for inserting an LED lamp, and a coil spring (appears in the figure). End cap abutting portion 0212 attached to the end cap. That is, the holding part has an abutting part holding part for holding the end cap abutting part, and a cylindrical part having an insertion opening corresponds to this in the example of this figure. In the example of this figure, an opening 0213 is provided near the insertion opening. This opening is for exposing the power interface to the outside as will be described later.

        (End cap contact part, contact part holding part)

  The “end cap abutting portion” is urged in a direction against an external force that abuts the end cap and moves toward the distal end side of the support pin. The “contact portion holding portion” is for holding the end cap contact portion. In the example of FIG. 2, this corresponds to the cylindrical portion of the holder that houses the end cap abutting portion 0212 therein.

  FIG. 2B shows an example of the shape of the end cap contact portion. The end cap abutting portion 0212 includes an annular member 0214 having an outer diameter substantially equal to the inner diameter of the cylindrical portion of the holding portion and an inner diameter substantially equal to the interval between the support pins, and a coil spring 0215 attached to the annular portion. The reason why the inner diameter of the annular portion is made substantially equal to the interval between the support pins is that when the support pins are inserted into the ring of the annular member, the support pins are inscribed in the ring so that the LED lamp does not wobble with respect to the holder ( This is to prevent the LED lamp from moving in the short direction. On the other hand, in the longitudinal direction of the LED lamp, the LED lamp is held by the urging force from the end cap contact portion of the holder.

  At this time, the tip of the coil spring may be fixed to the inner bottom of the cylindrical portion of the holding portion with an adhesive or the like, or may not be fixed. However, when one of the holding parts is mounted with the insertion port facing downward, as in the case where the LED lamp is mounted vertically on a wall or the like, the end cap abutting section abuts when the LED lamp is installed. Desirably, the tip of the coil spring is fixed to the inner bottom of the cylindrical portion of the holding portion. In addition, the structure and shape of the end cap abutting portion of this figure are merely examples, and for example, the end cap abutting portion is urged by a cylindrical rubber housed in the abutting portion holding portion instead of the coil spring. There may be.

  FIG. 3A is a diagram illustrating an example of a mounting structure of a straight tube type LED lamp with respect to a straight tube type LED lamp holder. 3A (a) is an example of a holder having the same structure and shape as that shown in FIG. 1 and the like, and this is shown in a vertical sectional view along the center line in the longitudinal direction of the LED lamp. . The cross section of the holder holding part is shown by a diagonal line rising to the right. In this figure, a straight tube type LED lamp 0330 is held by straight tube type LED lamp holders 0300 at both ends. Each holder holding portion has an abutting portion holding portion (cylindrical portion), and an end cap abutting portion 0312 in which a coil spring 0315 is attached to an annular member is housed in the abutting portion holding portion. (The cross-section of the annular member of the end cap abutting portion is indicated by a left-upward oblique line). The tip 0315a of the coil spring is fixed to the inner surface of the bottom 0316a of the contact holding part. In a state where the LED lamp is attached to the holder, the end cap contact portion is pressed by the LED lamp toward the bottom surface of the contact portion holding portion (arrow B direction). That is, an external force from the LED lamp toward the tip side of the support pin acts. Therefore, an urging force in the direction of arrow A acts from the left and right end cap abutting portions in a manner against this, and the LED lamp is held without falling.

  FIG. 3A (b) is a plan view showing the left holder shown in FIG. 3A and the vicinity thereof (however, the fixing part of the holder shows only the columnar part). As shown in the figure, an opening is provided near the insertion opening of the holder 0300. In addition, the end cap 0332 and the support pin 0331 of the LED lamp are held in a state of being inserted into the contact portion holding portion. In particular, the support pin is inserted so as to be inscribed in the annular member of the end cap contact portion 0312. Further, the end cap is provided with a power interface 0333, and an external power line 0341 is connected to the power interface. Thus, when the power interface is provided in the portion inserted into the abutting portion holding portion (near the end cap or the end of the tube), it is desirable to provide an opening for exposing the power interface to the outside. . This figure also shows an example in which an opening 0313 is provided for exposing the power interface provided in the end cap to the outside.

  FIG. 3B is a diagram illustrating an example of a mounting structure of a straight tube type LED lamp with respect to a straight tube type LED lamp holder, and an example of a holder having an end cap contact portion having a structure different from that illustrated in FIG. 3A Indicates. Among them, the one shown in FIG. 3B (a) is an annular portion 0300a having an inner diameter shorter than the outer diameter of the end portion of the end cap contact portion in the contact portion holding portion instead of fixing the tip end of the coil spring. The end cap abutting part is prevented from dropping from the holder by preventing the end cap abutting part from being hooked on the annular part and going further to the insertion port side. In addition, it may replace with an annular part and may provide some protrusions, and what kind of thing may be sufficient as long as it is a structure where an end cap contact part is hooked on this and it does not drop | omit.

  FIG. 3B (b) is the same as the example of (a) in FIG. 3B (b), but unlike (a), only a support pin (not shown in the figure) is inserted into the abutment holding part, and the end An example is shown in which the cap is not inserted. In this figure, the end cap is held in contact with the surface formed by the annular portion of the end cap contact portion located at the insertion port of the contact portion holding portion. In the case of such a configuration, unlike the case of (a), the end cap is not inserted into the closed space in the holding portion, and thus heat dissipation from the end cap can be performed more suitably. Become.

        (Installation procedure for LED lamps on holders with end cap contact parts)

  By providing the end cap contact portion, the LED lamp can be attached to the holder while the holder is still attached to the ceiling. That is, the one support pin of the LED lamp is pressed into the cylinder applied to the end cap contact portion of the one holder. At this time, in order to prevent the support pin or the like at the other end of the LED lamp from being attached to the other holder, the LED lamp is applied slightly obliquely to the contact surface of the end cap contact portion. Such an operation is possible by making the diameter of the tube slightly shorter than the inner diameter of the cylindrical portion of the holding portion. Then, push the end cap abutting portion into the cylinder until the tip of the other supporting pin does not replace the holder, and then straighten the LED lamp and place the other supporting pin in the end cap abutting portion of the other holder. Insert it into Moreover, you may provide the clearance gap for passing a support pin in the upper surface of the annular member of an end cap contact part in that case. In this way, in the above operation, it is not necessary to push the end cap abutting portion into the cylinder until the tip of the other support pin is in a position where it does not fit the holder.

        (End cap contact part: support pin insertion hole)

  On the other hand, the end cap contact portion may have the same shape as the socket of the straight tube fluorescent lamp instead of the annular member, that is, a support pin insertion hole. In this case, the support pin supports It will be held in a state of being inserted into the pin insertion hole. Also in this case, by combining with the configuration having the end cap contact portion, the LED lamp can be mounted while the holder is attached to the ceiling.

  A plurality of support pin insertion holes may be provided so that the angle can be selected and inserted. FIG. 4 is a diagram showing an example of the shape of the end cap abutting portion 0412 in the present embodiment, and when the LED lamp has two support pins on one side, the end cap abutting portion for inserting this is shown. An example in which six support pin insertion holes a, b, c are provided in total (three sets) is shown. By doing so, it is possible to select one of insertion holes a, b, and c and insert the support pin, thereby changing the irradiation direction of the LED lamp by changing the mounting angle of the LED lamp. Can do.

        (Opening to expose the power interface to the outside)

  Furthermore, the holding part may have an opening for exposing the power interface to the outside. Such a configuration is necessary to bring out the power line from the power interface when the power interface is housed inside the holding unit. For example, when the power interface is provided in the end cap and the length between the holders on both sides is less than the length of the tube of the LED lamp, the power interface is retained when the LED lamp is attached to the holder Such an opening is necessary because it is in a state of being housed inside the portion. An example of the shape of the holder having an opening is as shown in FIG. In FIG. 2, an opening 0213 is provided in the vicinity of the insertion port 0211 of the cylindrical holding portion (contact portion holding portion).

        (Holder (1) according to the form in which a plurality of LED lamps are connected and used)

  In the above description, the case where the LED lamp is used in a ceiling-mounted manner and the LED lamp is used as a single tube (single tube type) has been described. On the other hand, even if it is a ceiling installation type, the form (connection type) which connects and uses two or more LED lamps is also considered.

  FIG. 5 is a diagram showing an example of the shape of the straight tube type LED lamp holder according to the present embodiment, and is an example of the shape of the holder according to the use form in which a plurality of such holders are connected. The straight tube type LED lamp holder 0500 shown in this figure (a) is generally the same as the holder shown in FIG. 1, but unlike the one shown in FIG. 1, an insertion port 0511 for inserting the LED lamp is held. It is provided at both ends of the part.

  The specific configuration of the holding portion for holding the LED lamp is the same as that of the single tube. For example, two end cap abutting portions 0512 having a coil spring or the like in the cylinder of the holder holding portion. It can be considered that the LED lamp is held by an urging force in each direction with respect to the LED lamp inserted from both sides. In the case of the example of this figure, the holding part is penetrated in a form having insertion openings on both sides, and a member (for example, as shown in FIG. 3A (a)) for pushing back the end cap contact part against the external force from the LED lamp side. There is no such thing as the bottom face 0316 of the contact holding part. However, since the two end cap contact portions in the holding portion are pressed against each other by the external force from the LED lamp, a biasing force is generated in both directions, and the LED lamp can be suitably held. Alternatively, in order to prevent falling off when the LED lamp is mounted, the holding part does not penetrate and is partitioned by a wall near the center and a coil is fixed to each inner bottom. The inner wall may be provided with an annular portion or a protrusion. Note that the end cap contact portion may have a support pin insertion hole as in the case of a single tube.

  Even when a plurality of LED lamps are connected and installed, the holders arranged at both ends of the connected LED lamps only hold one LED lamp. In order to improve the appearance, a cap may be put on the side of the opening at both ends of the holding portion where the LED lamp is not inserted. Or you may use the holder for the above-mentioned single pipe only for this part. On the contrary, as a holder common to both the single tube type and the connection type, a connection holder as shown in FIG. 5 is used. You may make it use a cap on the side which does not insert an LED lamp among opening of both ends. By doing so, it becomes possible to further share parts, and further cost effects can be expected.

        (Holder (2) according to the form in which a plurality of LED lamps are connected and used)

  FIG. 6 is a diagram showing an example of the shape of the holder for the straight tube type LED lamp according to the present embodiment, and shows another example of the shape of the holder according to the use form in which a plurality of the holders are connected in a vertical sectional view. (However, the end cap contact portion shows the overall shape). In the example of this figure, an end cap abutting portion 0612 is provided in the holding portion of the straight tube type LED lamp holder 0600, and the end cap abutting portion has two approximately provided with support pin insertion holes 0612a. It consists of a cylindrical member 0614 and a coil spring 0615 connecting them. With such a configuration, the LED lamp can be easily attached as compared to the case where two separate end cap contact portions are provided in the holding portion.

  In addition, although the example of this figure also showed what the support pin insertion hole 0612a was provided with two or more sets (three sets), the objective is as having stated already.

        (Holder that prevents the power line from being exposed)

  In the above example, the power line from the outside such as the ceiling to the power interface is described as being exposed to the outside. On the other hand, the structure which accommodated the electric power line inside the holder and did not expose an electric power line outside is also considered.

  FIG. 11 is a diagram showing an example of the configuration of a straight tube type LED lamp holder according to the present embodiment, and shows a configuration in which a power line can be accommodated therein. In addition, since this figure is a conceptual diagram to the last, a specific shape is not necessarily restricted to this. (A) of this figure shows the holder attached to the LED lamp in a vertical sectional view along the center line in the longitudinal direction of the LED lamp. Cross sections of the holding part 1110 and the fixing part 1120 of the holder 1100 are indicated by oblique lines rising to the right. In this figure, unlike the example of FIG. 3A described above, the fixed portion covers the upper portion of the power interface 1133 and has a space for accommodating the power line 1141 connected to the power interface. Further, the fixed portion has a power line passage hole 1121 for taking in the power line drawn from the ceiling into the space. An example of the shape of the power line passage hole 0221 shown in a perspective view in FIG. 2 (c) is shown (note that FIG. 2 (c) shows only an example of the shape of the power line passage hole, and the shape of the holder itself is not necessarily It does not show the shape of the holder that prevents the power line from being exposed).

  When the fixing portion is attached to the ceiling, the power line passage hole is attached to the position of a hole (hereinafter referred to as “ceiling hole” for convenience) drilled in the ceiling in order to draw the power line from the ceiling. With such a configuration, the power line drawn from the ceiling hole is directly taken into the space of the holder (fixed part) through the power line passing hole and connected to the power interface covered with the fixed part. Therefore, the power line is not exposed to the outside at all, and the appearance can be made clear. FIG. 11B is a perspective view showing the state of FIG. This figure shows that all the power lines are housed in the holder and cannot be seen from the outside.

  As a method of attaching the LED lamp using such a holder, for example, first, for convenience of work, the power line is drawn out a little longer from the ceiling hole and the power line passage hole, and the power line is taken into the holder space. And a power line is connected to the power interface of the LED lamp with which the holder was mounted | worn. Alternatively, the LED lamp may be attached to the holder after connecting a power line drawn out through the insertion port of the holder to the power interface of the LED lamp before being attached to the holder. And what is necessary is just to adjust the length of the electric power line accommodated in holder space by returning a part of electric power line pulled out long through a power line passage hole and a ceiling hole to the ceiling back. In order to perform such work easily, an opening 1101 is provided on the LED lamp side (that is, the power interface side) of the fixed portion, and the power line is connected to the power interface through the opening or a part of the power line is connected. The work of returning to the back of the ceiling may be performed.

  In addition, although this figure demonstrated in the example of the single tube | pipe type holder among ceiling installation types, it is the same also in the case of a connection type. FIG. 5B shows an example of the shape of the power line passage hole 0521 shown in a perspective view (FIG. 5B also shows an example of the shape of the power line passage hole, and the shape of the holder itself is not necessarily It does not show the shape of the holder that prevents the power line from being exposed). In this case, when the power interfaces of two adjacent LED lamps are arranged at positions facing each other, two power lines connected to the respective power interfaces are drawn out through one power line passage hole of the fixed portion. Become.

    (Holder according to other usage)

  Next, usage forms other than the ceiling-mounted type will be described.

        (Floor type)

  As a usage form of the LED lamp, a form in which the LED lamp is used standing on a floor or a table (hereinafter referred to as “floor-placement type”) is also conceivable.

  FIG. 7 is a diagram showing an example of the shape of the straight tube type LED lamp holder according to the present embodiment, and shows an example of the shape of the holder corresponding to the floor-standing type.

That is, in any of the above various usage forms, the LED lamp can be used as an instrument simply by attaching the holder of this embodiment to the LED lamp. For example, it can be used as a ceiling lighting device simply by attaching a holder to the ceiling and then attaching an LED lamp. The same applies to other floor-standing types and hanging types.

  Also, for example, a single holder such as a ceiling-mounted single tube holder and a connection end holder can be used in common for different usage forms, and parts can be shared. Will also be possible and will contribute to the cost.

  <Effect>

  According to the invention of this embodiment, a compact for easily attaching to a straight tube type LED lamp configured not to receive power supply from a support pin and enabling the use of the LED lamp according to various usage forms. It is possible to provide a simple holder and a lighting device having the holder.

  <Overview>

  The straight tube type LED lamp holder of the present embodiment is basically the same as the holder of the first embodiment, but is characterized in that the fixing portion is configured to be detachable from the holding portion.

  <Configuration>

  FIG. 9 is a diagram illustrating an example of the shape of a straight tube type LED lamp holder according to the present embodiment. This figure is an example of a holder corresponding to a single tube type LED lamp installed on a ceiling or the like. FIG. 9A shows the holder in a state where the fixing portion is attached to the holding portion. As shown in this figure, the straight tube type LED lamp holder 0900 of the present embodiment has a holding part 0910 and a fixing part 0920. The feature of the holder of the present embodiment is that the fixing portion is configured to be detachable from the holding portion. For this reason, the fixing portion and the holding portion each have an attachment / detachment interface that is a mechanism for attachment / detachment.

  FIG. 9B shows a state where the fixing part is separated from the holding part. In this example, as the attachment / detachment interface on the holding unit side, a convex portion 0911 having a substantially prismatic shape with a substantially trapezoidal bottom surface is provided on the surface in contact with the fixing unit of the holding unit. On the other hand, as shown in FIG. 9C, a concave portion 0921 having a shape corresponding to the convex portion is provided on a surface (hereinafter, referred to as “fixed surface” for convenience) 0920a that is in contact with the holding portion of the fixed portion 0920 as an interface on the fixed portion side. It is done. Then, the fixing part and the holding part can be attached / detached with the convex part provided on the holding part on the end face of the concave part provided on the fixing part (the bottom end surface of the concave part indicated by the broken line circle 0921a in FIG. 9B). The top surface 0911a is applied, and the convex portion is slid in a direction perpendicular to the bottom surface of the convex portion (in the direction of arrow C in the figure). That is, in this example, the detachable interface is a slide mechanism. At this time, as shown in FIG. 9C, it is desirable that the concave portion is not provided so as to penetrate through the fixed surface, but is provided in such a form that one end portion is dead end in the middle of the fixed surface. At this time, the dimension of the concave part is designed in accordance with the dimension of the convex part. By doing so, it is possible to easily realize a state in which the fixing portion and the holding portion fit snugly by sliding the convex portion to a position where it hits the end portion of the concave portion and becomes a dead end. In addition, the shape of the concave part and the convex part shown in the figure is merely an example, and the shape is suitable for both, and the shape (the convex part is not naturally separated when the concave part and the convex part are attached). Any shape is acceptable as long as the shape spreads toward the fixed portion.

  The specific shapes of the convex part and the concave part are appropriately designed according to the mounting direction of the fixing part. For example, when the fixing part is attached to the ceiling surface, for example, the concave part of the fixing part is on the ceiling side (side closer to a substantially elliptical plate-like part) so that the holding part does not slide down and fall off. It is conceivable that the floor side which is the opposite side has a closed state, having an opening only on the side. 9 (a) to 9 (c) are shapes suitable for mounting the fixed portion on a wall or floor, and the mounting of the fixed portion and the holding portion when installed on the ceiling is an example of the same figure. Unlike, for example, the recessed part of the fixed part has an opening only on the ceiling side (side close to the substantially elliptical plate-like part), and the opposite floor side is closed. Conceivable. In this case, the fixing part and the holding part may be mounted by attaching the convex part of the holding part to the opening part on the ceiling side of the concave part of the fixing part and sliding the convex part downward.

  Or when attaching a fixing | fixed part to a ceiling surface or a floor surface, you may make it provide the sliding mechanism of the direction which slides in a horizontal direction instead of a perpendicular direction.

  Or you may make it attach the attachment / detachment interface of a fixing | fixed part rotatably with respect to a fixing | fixed part main body. In the example of FIG. 9C, a substantially cylindrical diameter portion (a portion indicated by oblique lines) including the concave portion may be rotatably attached to the rear fixed portion main body in the direction of arrow D. . In this case, after attaching the LED lamp to the holder, if the holding part is rotated so that the opening of the recess does not face downward, the holding part slides downward and falls off. It can be eliminated or the opening can be made inconspicuous.

  Furthermore, the holder of the present embodiment may be provided with a slide mechanism that can be slid in any direction among the vertical direction and the horizontal direction. FIG. 9D shows an example of a holder having such a slide mechanism. In the example of this figure, the fixed portion 0920 is provided with two concave portions 0921a and 0921b in the vertical direction and the horizontal direction so as to intersect the cross. The shape of each recess is the same as the recess shown in FIGS. On the other hand, the holding portion is provided with a convex portion having the same shape as that shown in FIGS. Therefore, when the convex portion of the holding portion is slid and attached to the concave portion of the fixed portion, an arbitrary concave portion can be selected and attached according to the mounting direction of the fixed portion. For example, when the fixed part is attached to the ceiling or floor, it is only necessary to select and install a horizontal recess. When the fixed part is attached to a vertical wall, select and install the vertical recess. do it. In this way, the holder can be made into a single shape regardless of the mounting direction of the fixing portion, that is, regardless of the usage form, and the manufacturing cost can be saved.

  Further, the attachment / detachment interface is not limited to a slide mechanism, and any mechanism may be used as long as it has a shape / structure that can be easily attached / detached. For example, a mechanism that performs adhesion / removal using a magnet or the like, or a mechanism that uses a male screw / female screw to attach / detach can be used.

  In addition, as a configuration for the holding portion to hold the LED lamp, in the example of this figure, the cylindrical holding portion is divided into a plurality of blade-like portions, like the hanging type of the previous embodiment, A claw is provided at the tip of the wing-like portion to hook onto the protruding portion near the end of the LED lamp.

  FIG. 10 is a diagram showing another example of the shape of the straight tube type LED lamp holder of the present embodiment, and corresponds to a use form other than the type shown in FIG. 9 (single tube type ceiling-mounted type). The shape of a holder is shown. FIG. 10A shows an example in which the shape of the holder corresponding to the connection type ceiling installation type is removed. The holder 1000 shown in this figure has two holding portions 1010 and one fixing portion 1020. In the example of this figure, the same attaching / detaching mechanism as that of the holder shown in FIG. 9 is used. That is, concave portions similar to those shown in FIG. 9 are provided on both sides of the fixed portion, and each holding portion is provided with convex portions similar to those shown in FIG. The fixing part and the holding part are attached and detached by sliding the convex part into the concave part. In addition, the attaching / detaching interface of the fixing portion shown in the figure is also an example in consideration of what is rotatably attached to the fixing portion main body.

  FIG. 10B shows an example of the shape of the holder corresponding to the floor-standing type, and FIG. 10C shows an example of the shape of the holder corresponding to the hanging type. These examples also use an attachment / detachment mechanism similar to that shown in FIGS. 9 and 10A.

  Thus, in the holder of the present embodiment, by unifying the attaching and detaching mechanism of the fixing part and the holding part, the holding part has a single shape and structure regardless of the usage form, and the fixing part is Although the overall shape depends on each usage pattern, the shape and structure for attaching to and detaching from the holding part are common regardless of the usage pattern. Therefore, according to the present embodiment, the holding unit can be shared, and the same holding unit can be used for various usage modes. For this reason, manufacturing cost can be saved, and when only the holding part is damaged, only the holding part can be replaced with common parts, which is convenient.

  <Effect>

  According to the invention of the present embodiment, it is possible to provide a variation of a compact holder that can be easily attached by using a part of a common part while minimizing the number of parts.
