Description

  The present invention relates to a reflector-equipped lamp mainly used for general illumination and a manufacturing method thereof.

  PAR-type lamps are known as reflector-equipped lamps used for general lighting applications, particularly store lighting. In this case, a compact tube-shaped light source is housed in a reflecting mirror, and the light center of the light source and the focal position of the reflecting mirror are matched and fixed integrally. The reflector-equipped lamp is required to have the same light distribution characteristics if it is a product of the same product type due to its characteristics. This is a very important factor in lighting design. An incandescent lamp, a halogen lamp, a high-pressure steam discharge lamp, or the like is used as the light source.

On the other hand, a PAR lamp in which a ceramic metal halide lamp is housed in a reflecting mirror has been developed in recent years. When the light source as described above is housed in the reflecting mirror, a configuration for fixing the light source to the reflecting mirror is required. As an example, for example, in Patent Document 1, a disk-shaped plate and a seal portion are positioned using a protrusion provided on the seal portion, and the plate and the reflection plate are disposed after they are arranged inside the reflector. The three parts are fixed to each other by filling a space formed by the inner wall of the mirror and the seal portion with a large amount of adhesive.
In Patent Document 2, an eyelet is provided at the end of the reflecting mirror, and an electrode extending from the seal portion is inserted into and fixed to the eyelet. And in patent document 3, it fixes so that a light source may be inserted | pinched inside a reflective mirror by interposing an attachment member between a reflective mirror inner wall and a seal | sticker part.

  By the way, conventionally, halogen lamps with reflectors, etc. are actually turned on before inserting and fixing the lamp in the reflector to obtain the same light distribution characteristics. After confirming the measurement using the lamp, the lamp and the reflector are fixed, and the same type has been manufactured with the same light distribution and illuminance.

  However, it takes a relatively long time to adjust the position of the reflector and the lamp after waiting until the light emission state of the lamp is stabilized. In particular, when a high-intensity discharge lamp is used as a light source in combination with a reflecting mirror, there is a drawback in that sufficient lamp performance cannot be achieved unless the discharge lamp is lit for 10 minutes or more from the lamp lighting to the stability. In addition, after the lamp has been steadily lit, the light source is in a high temperature state. If an adhesive is injected between the light source and the reflector, bumping may occur instantaneously, which may cause unstable conditions in the adhesion state. give.

  If it is not necessary to turn on the light source during lamp assembly, the manufacturing process can be simplified. That is, a reference location is provided outside the light source with respect to the light center of the light source, and the light source is manufactured with an accuracy that the positional relationship between the light center position and the reference position is within an allowable dimension. In other words, a configuration in which a position is determined and combined may be adopted.

Here, when the configuration of the prior art is examined, in the case of Patent Document 1, since there is no portion or member for positioning between the plate and the reflector, the light source position is fixed by focusing by lighting the lamp. This is premised on (because the positional relationship between the light source and the plate depends on the processing accuracy of the seal part (glass), their positioning accuracy cannot be expected).
In addition, as a problem different from assembly, in this bonding method, the adhesive absorbs moisture during the lamp life, the insulation resistance decreases, and the probability that discharge through the adhesive occurs between the power supply lines of the light source becomes high. There is also a problem of end.

  In the thing of patent document 2, processing, such as attaching an eyelet to the rear part of a reflective mirror, is needed. Further, since the position of the light source is fixed by fixing the lead wire protruding from the light source to the eyelet, there is a concern that the lead wire sealing portion is broken or the lead wire is broken due to vibration shock during the lamp transfer. In particular, when a high-pressure steam discharge lamp such as a ceramic metal halide lamp is used as the light source, the mass of the light source tends to increase, so that the risk of damage to the lead wire sealing portion increases. Moreover, in the thing of patent document 3, in order to fix a light source, a more complicated component than patent document 2 is needed.

Therefore, the configuration of the above-mentioned patent document cannot achieve the positioning of the light source or requires a complicated configuration even if it can. On the other hand, if a compact lamp standard product such as G8.5 can be used as the light source, the manufacturing process can be made common, and further advantageous in terms of inventory management and manufacturing cost reduction.
The present invention provides a reflector-equipped lamp having a simple component configuration, which can mechanically align the light center of the light source and the focal position of the reflector and integrally fix them without turning on the light source, and a method for manufacturing the same. The purpose is to provide.

  According to a first aspect of the present invention, there is provided a light source comprising an airtight container having a seal portion at one end and projecting two power supply lines, an irradiation opening and a bulge at opposite ends on the optical axis. A lamp with a reflecting mirror having a reflecting mirror having a protruding portion and a disk for fixing the sealing portion to the bulging portion, the disk having a disk hole for penetrating the sealing portion, and on the disk The four discs partitioned by an axis (x axis) extending in the width direction of the disk hole portion through the center of the disk hole portion and an axis (y axis) extending in the longitudinal direction of the disk hole portion through the center of the disk hole portion. This is a lamp with a reflecting mirror in which a seal portion and a disk are bonded in four independent bonding regions distributed in the region.

In the first side surface, the cross section cut in the xy-axis plane of the seal portion is positioned to face the first region including the two power supply lines and the y-axis direction end of the first region. And the second and third regions projecting in the x-axis positive and negative directions with respect to the first region, and the four adhesion regions are defined by two corners defined by the first region and the second region And two corners defined by the first region and the third region.
Moreover, the cross section cut | disconnected by the xy-axis plane of a seal | sticker part has a rectangular shape, and let the said 4 adhesion | attachment area | region be the area | region which contact | connects the rectangular four corners.
Further, when the optical axis is the z-axis, when the disc and the seal portion are bonded, the direction in which the feed line protrudes is the z-axis positive direction, and the direction in which the irradiation opening is located is the z-axis negative direction. Each of the two bonding areas is defined by a side surface facing the disk hole of the disk and a side surface of the seal part attached to the disk, and is open in the positive z-axis direction and has a concave space having a bottom surface in the negative z-axis direction. The configuration is as follows.

According to a second aspect of the present invention, there is provided a light source including an airtight container having a seal portion at one end and protruding a power supply line, and an irradiation opening and a bulging portion at opposite ends on the optical axis. And a reflector-equipped lamp provided with a disk for fixing the seal part to the bulging part, wherein the disk can be inserted into the bulging part, a collar part on the outer periphery of the disk, and It has a disk hole that penetrates the seal part in the optical axis (z-axis) direction, and is provided at two or more locations on the outer periphery of the cylindrical part, and has an outer recess that opens in the cylindrical part buttock direction. It was set as the structure with which the adhesive agent was filled in the space defined by the recessed part and the bulging part inner surface.
Furthermore, the z-axis direction cross section of the space defined by the outer concave portion and the inner surface of the bulging portion has a tapered shape that narrows toward the bulging portion end.

  According to a third aspect of the present invention, there is provided a method of manufacturing a lamp with a reflecting mirror, which is a combination of a light source that defines a distance from the optical center to the end of a feeder line, and a reflecting mirror. 6. The disk according to claim 1, wherein a step of supporting a reference plane perpendicular to the optical axis (z-axis) provided in the irradiation side opening of the light source by a reflecting mirror reference receiver, and a seal portion of the light source. And determining the positional relationship between the disc hole portion and the seal portion in the direction perpendicular to the optical axis (xy plane), inserting the light source and the disc through the bulge portion side opening of the reflector, and the reflector reference The step of inserting the light source into the tilt regulating tube supported perpendicularly to the receiver, the light source is z-axis with respect to the reflector so that the difference between the z-coordinate of the reference plane and the z-coordinate of the feeder line end becomes a specified value. Positioning step for adjusting the direction, sealing part and disk, and The disk and the bulge portion is a manufacturing method comprising a bonding step of bonding by an adhesive.

  According to a fourth aspect of the present invention, there is provided a reflecting mirror having a light source seal portion composed of an airtight container with two power supply lines projecting at one end, and an irradiation opening and a bulging portion at opposite ends on the optical axis. A disk for fixing to a bulging part, the disk having a disk hole part for penetrating the seal part, and further passing through the center of the disk hole part on one surface of the disk and the width of the disk hole part Of four concave portions distributed in four regions of the disk partitioned by an axis extending in the direction (x axis) and an axis extending through the center of the disk hole portion and extending in the longitudinal direction of the disk hole portion (y axis) The disk has a region, and each of the four recessed adhesive regions faces the disk hole.

  According to a fifth aspect of the present invention, there is provided a reflecting mirror having a light source seal portion composed of an airtight container with two power supply lines protruding at one end, and an irradiation opening and a bulging portion at opposite ends on the optical axis. A disk to be fixed to the bulging part, and a cylindrical part that can be inserted into the bulging part, a collar part provided at two or more places on the same plane on the outer periphery of the disk, and a seal part in the optical axis direction A swelled end portion at the outer peripheral part of the cylindrical part for forming a bonding space between the swelled part and the cylindrical part when the cylindrical part is inserted into the swelled part. This is a disc provided with two or more outer recesses opened in the direction.

  According to the present invention, since there are four points for fixing the light source to the disk, the resistance against the external force that tilts the light source with respect to the disk is increased, the defects during the assembly of the lamp with the reflector are reduced, and the vibration during the transfer is -Durability against impact can be improved. Moreover, there is an advantage that the amount of adhesive consumption can be reduced when the light source is fixed to the disk.

  Further, since there is no adhesive between the power supply lines, discharge between the power supply lines is less likely to occur due to a decrease in the insulation resistance of the adhesive during the lamp life.

  In addition, each recess provided in the disc has a narrow gap on the reflecting surface side when combined with a seal or a reflecting mirror. Therefore, when the gap is filled with an adhesive, the adhesive is on the optical center side. Leakage can be suppressed. With this configuration, workability is improved when the disk and the reflecting mirror bulge are bonded, and the adhesive is prevented from flowing out to an unnecessary portion.

  After the adhesive filled in the outer concave portion is cured, the disc does not come off from the reflecting mirror due to the wedge effect even if the adhesive is peeled off from the reflecting mirror. Since the step of fixing the disc to the seal portion of the light source and the step of fixing the disc to the reflecting mirror can be performed simultaneously, the number of manufacturing steps can be reduced.

  With the above configuration, each member can be positioned, so that the optical center of the light source and the focal point of the reflecting mirror can be aligned and fixed without turning on the light source. As a result, the light source stabilization wait time and the light source cooling time after alignment are not required, and the assembly work time is greatly reduced. Furthermore, if the adhesive is filled before the light source and the reflector are sufficiently cooled, an adhesive bumping phenomenon may occur. However, if the light source is not turned on, the temperature of the light source and the reflector will not rise. It can't happen.

  From the above, the elements constituting the lamp with a reflecting mirror can be equal to or less than the conventional one. That is, it is not necessary to add a special shape to a part of the reflecting mirror and the light source, they can be easily molded, and the processing yield can be improved.

  FIG. 1 is a longitudinal sectional view showing an embodiment of a lamp with a reflector according to the present invention. In the figure, reference numeral 10 denotes the same light source as that shown in FIG. 3, and the position indicated by a black circle at the center is the optical center 2 of the light source. In FIG. 1, reference numeral 11 denotes the same reflector as shown in FIG. 4, and the position indicated by the multiplication symbol at the center of FIG. 4 is the reflector focus 12. A front glass 13 for controlling the light distribution is provided on the side where the reflecting mirror 11 is irradiated with light, and a base 14 for supplying power is provided on the opposite side. The light source 10 and the reflecting mirror 11 are bonded and fixed, and are fixed at a position where the optical center 2 indicated by a black circle in the light source and the reflecting mirror focal point 12 coincide.

In FIG. 1, reference numeral 100 denotes a positioning disk (hereinafter referred to as “positioning disk” or “disk”), and details are shown in FIGS.
As shown in FIG. 6, the disc 100 is provided with disc hole portions 101, and inner concave portions 102 are provided at four locations inside thereof. As shown in the BB cross section of FIG. 6, the inner recess 102 has a left-side interval narrower than a right-side interval in the BB cross-section. This disc 100 is designed so that the left side of the BB cross section is inserted into the reflecting mirror 11. Further, the outer periphery of the disk 100 has a shape that is chamfered on only two surfaces in parallel. Each chamfered portion is provided with an outer recess 103. As shown in the CC cross section of FIG. 6, the outer recess 103 is smaller on the left side of the CC cross section. The disk 100 is bonded and fixed to the light source 10 inserted into the disk hole 101 and is also fixed to the reflecting mirror 11 at the same time.

As shown in FIGS. 7 and 9, the seal portion 1 is inserted into the disc hole portion 101 of the disc 100. After the insertion, the disc and the light source are bonded and fixed by injecting the light source adhesive 105 into the four positions indicated by triangular marks in FIG. The bottom of the inner recess 102 prevents the light source adhesive 105 from flowing out to an unnecessary portion.
On the other hand, as shown in FIGS. 8 and 9, the disk 100 is inserted into the reflecting mirror bulging portion 18, and the adhesive for the reflecting mirror 106 is injected into two positions indicated by the pentagonal mark in the drawing, thereby The reflector is bonded and fixed.
The above two bonding operations can be performed simultaneously.

  Here, with respect to the cross section of the seal portion 1 in the direction perpendicular to the optical axis (xy plane), in this embodiment, a symmetrical shape (symmetrical H shape) is used with respect to the x axis and the y axis. Even when the shape is used, the shape of the disk hole 101 may be changed in accordance with the shape. As the cross section of the H-shaped seal portion that is not symmetrical, for example, a trapezoidal shape as shown in FIG. 10A or a parallelogram shape as shown in FIG.

Next, a specific example of the alignment method will be described below with reference to the drawings.
FIGS. 2 to 5 show an example of a method for manufacturing a lamp with a reflector according to claim 4 of the present invention, using a partial cross-sectional view, for explaining a part of the process of creating the light source 10. FIG. The arc tube 3 and the supporting / feeding member are inserted into the tare 4 and the lower part of the tare is heated and sealed to produce the light source 10 shown in FIG. In this embodiment, it is sealed with a pinch seal. In the figure, the position indicated by a black circle at the center of the arc tube 3 is the optical center 2 of the light source 10.

  The manufacturing method of the light source in this embodiment is the same as the lamp manufacturing method of the G8.5 specification. In the lamp of G8.5 specification, the light source is processed so that the dimension LA to the optical center is within the tolerance with reference to the tips of the pair of feeder lines 6, that is, the position 9 in FIG. Therefore, the light source 10 used in this embodiment can use the lamp material and manufacturing equipment of G8.5 specification as it is. Alternatively, a G8.5 specification lamp may be used as it is. In the present embodiment, the tip of the feeder 6 is the light source position reference 9.

4 and 5 are explanatory views of a process of combining the light source and the reflecting mirror so that the optical center position and the reflecting mirror focal position are matched and bonded and fixed.
The jig D41 is provided with a reflecting mirror reference receiver 49, and supports the reflecting mirror 11 with its central axis kept vertical. At the same time, it comes into contact with a reflecting mirror reference surface provided in the reflecting mirror and becomes a reference for defining the position of the reflecting mirror reference surface on the jig D. Further, a relief hole is provided so that a part of the light source 10 protruding from the reflecting mirror 11 does not hit the reflecting mirror reference receiver 49.

On the other hand, the light source 10 is set on the jig D41. The light source 10 is held perpendicular to the plane of the reflector reference receiver 49 by an inclination regulating tube 42 and a spring 43.
A light source reference receiver 48 is provided on the jig D41. The light source reference receiver 48 can be slid to change its height. The height of the light source reference receiver 48 is defined by the stopper 45. This height LJ is set to coincide with the sum of the distance LA from the light source position reference 9 to the optical center and the distance LE from the reflector position reference 15 to the reflector focus 12.

  Here, a vent hole for ejecting air, hot air or inert gas from the reflector reference receiver 49 is provided. Depending on the type of adhesive, an oxidizing or reducing gas may be flowed.

The manufacturing method in the present embodiment using these members and jigs is as follows.
(A) As shown in FIG. 2, the distance LA from the end of the feeder 6 to the optical center 2 is made constant, and the light source 10 is manufactured in the same manner as a normal G8.5 specification lamp. After completion of the light source, the end of the feeder 6 becomes the light source position reference 9 as shown in FIG.
(B) As shown in FIG. 4, the light source 10 is inserted into the inclination regulating tube 42. The light source 10 is not lowered by its own weight by a method such as cutting out a part of the inclination regulating tube 42 and applying a spring. If the optical center 2 is set so that the position of the optical center 2 is slightly above the specified position, the subsequent work can be easily performed.
(C) Place the reflecting mirror 11 on the jig D41 from above the light source 10. At this time, the reflector position reference 15 is set so as to contact the reflector reference receiver 49. Since the convex portion of the reflector reference receiver 49 is circular and the cross section of the reflector perpendicular to the central axis is also circular, the reflector focal point 12 extends from the center point of the reflector reference receiver 49 convex portion to the convex surface of the reflector reference receiver 49. On the orthogonal alignment axis 50.
(D) Insert the disc 100 into the seal portion of the light source 10. The disc 100 is pushed in until the flange portion 104 contacts the end face of the reflecting mirror 11.

(E) As shown in FIG. 5, the slide plate 46 is lowered to a height corresponding to the stopper 45 while the light source reference receiver 48 contacts the light source position reference 9. At this time, the distance LJ between the light source reference receiver 48 and the reflector reference receiver 49 coincides with the sum of the distance LA from the light source position reference 9 to the optical center and the distance LE from the reflector position reference 15 to the reflector focus 12. The positions of the optical center 2 and the reflector focus 12 coincide.
(F) In the state of the previous item, as shown in FIGS. 8 and 9, the adhesives 105 and 106 are filled and temporarily dried. At this time, if hot air or the like is blown from the lower part of the jig D41, the time required for temporary drying can be shortened.
(G) Several to hundreds of light sources with reflecting mirrors after temporary drying are put together in a drying furnace (not shown), and the adhesive is completely dried.

  Thereafter, the front glass is bonded by a normal method, and the base is attached, so that a reflector-equipped lamp in which the optical center 2 and the reflector focal point 12 coincide can be easily manufactured.

In the said Example, although the example which attaches a light source whose seal | sticker part cross section is H shape to a reflective mirror was shown, the case where a seal | sticker part cross section is a rectangle is shown as another example.
FIG. 11 is a view of the disk 100 and the light source 10 in this embodiment as viewed from the feeder line side. The seal portion 1 is rectangular, and the four inner concave portions 102 are provided at positions where the four inner concave portions 102 are in contact with the four corner portions of the rectangle. The inner recess 102 in FIG. 11 differs from the inner recess 102 in FIG. 6 in the xy plane, but the configuration in the z-axis direction of both is similar. That is, the side surface and the bottom surface constituting the inner recess 102 are defined by the side surface facing the disk hole portion 101 of the disk 100 and the side surface of the seal portion 1, and the bottom surface is located at a certain depth on the disk 100. is doing.

Although the above embodiment shows the most preferable one, the following modifications can be made, for example, within a range not departing from the gist of the present invention.
(1) In the embodiment, the present invention has been described with respect to a built-in discharge lamp arc tube as a light source. However, even when an incandescent lamp such as a single-ended halogen lamp having a similar shape is used as a light source, the same applies. An effect can be obtained.
(2) Although the G8.5 type light source is used as a general light source in the embodiments, the present invention can be applied to other shapes and rated power.
(3) In the embodiment, ceramics are used for the disk 100, but other materials such as metal can be used.
(4) In the embodiment, as a most preferable example, the light source and the disk are bonded at the minimum necessary four points. However, if the bonded areas are distributed in four independent areas, five or more points are bonded. The same effect as in the embodiment can be expected with respect to the adhesive state after drying.
(5) Similarly, in the embodiment, as the most preferable example, the reflecting mirror and the disk are bonded at the minimum two points, but three or more outer concave portions having the same configuration may be provided. With respect to the adhesive state after drying, the same effects as in the examples can be expected.
(6) In the embodiment, as shown in FIG. 8, the side surface of the disk is chamfered in the vicinity of the outer recess 103, and as a result, the flange portion 104 of the disk 100 is divided into two parts. You may make it provide in the whole.
(7) Regarding the wedge effect by the outer concave portion 103 in FIG. 9, the inclination of the reflecting mirror bulging portion 18 is used in the embodiment, but even if the wedge shape is formed by giving an inclination to the side wall of the outer concave portion of the disk. Good. In any case, it is only necessary to form a taper in which the space defined by the outer recessed portion 103 and the reflecting mirror bulging portion 18 becomes narrower upward (in FIG. 9).
