Description

  The present invention relates to a lamp with a reflector mainly used for general illumination.

  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, in recent years, a PAR lamp in which a ceramic metal halide lamp is housed in a reflecting mirror has been developed. 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 in the inside of a reflecting mirror by interposing an attachment member between a reflecting mirror inner wall and a light source seal 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, the above method has a disadvantage 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. It is assumed that this is done.
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 or the like during 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 manufacturing method of a lamp with a reflecting mirror that can be fixed integrally with a simple component configuration without mechanically turning on the light source by mechanically matching the optical center of the light source with the focal position of the reflecting mirror. The purpose is to provide.

  A first aspect of the present invention is a method for manufacturing a reflector-equipped lamp in which a light source and a reflector are combined. The light source seals one of a substantially cylindrical tare, an arc tube held inside the tare, and a tare. A light source reference position having a predetermined positional relationship from the light center inside the arc tube, the reflecting mirror has a bulging portion to which the seal portion is fixed, An optical axis is formed with an opening for light irradiation, a reflector reference position having a predetermined positional relationship from a focal point formed on the optical axis is provided, and the manufacturing method is in a state where the light source is turned off. A positioning step of determining a relative position of the light source with respect to the reflecting mirror based on the reflecting mirror reference position or the reflecting mirror secondary reference position determined based thereon and the light source reference position or the light source secondary reference position determined based thereon; Bonding to bond mirror and light source Is a manufacturing method comprising the degree.

In the first aspect, the positioning step applies the reflecting mirror reference position or the reflecting mirror secondary reference position determined based thereon and the light source reference position or the light source secondary reference position determined based thereon via the attachment member. It was set as the structure which consists of a process to contact | connect.
Here, the attachment member is a positioning plate attached in advance to the light source, and the distance between the end of the power supply line and the surface on the power supply line side of the positioning plate is attached with a predetermined distance in the optical axis direction. The positioning step is performed with the light source 2 at the reflector reference position, with the reflector reference position as the internal end face inside the bulge, the light source reference position as the feed line end, and the light source secondary reference position as the feed line side face of the positioning plate. The step consists of a step of bringing the next reference position into contact.
Further, the attachment member is a positioning plate attached in advance to the light source, and the distance between the end of the feeder line and the surface on the optical center side of the positioning plate is attached at a predetermined distance in the optical axis direction, Reflector reference position is a plane perpendicular to the optical axis provided on the inner end face or opening of the bulging part, Reflective secondary mirror reference position is an external end face cut at a predetermined distance from the reflector reference position, and light source reference position The positioning step includes the step of bringing the light source secondary reference position into contact with the reflection secondary mirror reference position, with the end of the feeder line and the light source secondary reference position as the surface on the optical center side of the positioning plate.

Further, in the first aspect, the positioning step may include a reflecting mirror reference position or a reflecting mirror secondary reference position determined based on the reflecting mirror reference position and a light source reference position or a light source secondary reference position determined based on the reflecting mirror reference position. And a step of contacting a fixed jig that defines a relative position between the light source and the light source reference position.
Here, the light source has a shoulder portion that forms the other end surface of the tare, the reflector reference position is a plane perpendicular to the optical axis provided in the opening, and the light source reference position is the shoulder portion, and the positioning step includes: The reflection mirror reference position and the light source reference position are configured to simultaneously contact the fixed jig.
In addition, the positioning plate is attached to the light source in advance, and the distance between the end of the feeder line and the surface on the optical center side of the positioning plate is attached at a predetermined distance in the optical axis direction, and the reflector reference position is opened. The positioning step is performed by using the surface perpendicular to the optical axis provided in the section, the light source reference position as the end of the feeder line, and the light source secondary reference position as the surface on the optical center side of the positioning plate. The reference position and the fixed jig are simultaneously brought into contact with each other.

  Further, the light source has a head protruding on the optical axis at the other end of the tare, the reflecting mirror reference position is a plane perpendicular to the optical axis provided in the opening, and the light source reference position is the head, and the positioning step However, the configuration includes a step of simultaneously bringing the reference position of the reflector and the reference position of the light source into contact with the fixed jig.

In the first aspect, the positioning step includes a temporary positioning step and a main positioning step. The temporary positioning step sets the reflecting mirror reference position on the fixed jig, and the light center of the light source is attached to the optical axis by the mounting member. And positioning the light source on a semi-fixed jig that can be slid and stopped, and this positioning step includes the z coordinate of the reflector reference position and the z of the light source reference position with the optical axis direction as the z axis. The relative position between the light source and the reflecting mirror is adjusted by a movable jig so that the difference from the coordinates becomes a specified value.
Here, the positioning step is performed from the step of adjusting the position of the feeder line end by a movable jig, with the reflector reference position as a plane perpendicular to the optical axis provided in the opening and the light source reference position as the feeder line end. It became the composition which becomes.
In addition, the reflector reference position is a support region inside the bulging portion, the light source reference position is the feed line end, and the positioning step includes a step of adjusting the position of the feed line end by a movable jig. .

  Furthermore, in the above, a drying step of ventilating from the opening direction of the reflecting mirror toward the bulging portion with the reflecting mirror and the light source mounted on the fixed jig may be included.

  The second aspect of the present invention is a lamp with a reflecting mirror manufactured by any one of the above manufacturing methods.

According to the present invention, it is possible to fix the position by matching the optical center of the light source and the focal point of the reflecting mirror 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.
Here, 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. Can't happen.

Furthermore, the number of elements constituting the lamp with a reflector is the same as or less than that of the conventional one, and the shape of the lamp component with a reflector can be simplified.
At the same time, since the central axis of the light source and the optical axis of the reflecting mirror are made coincident, the cement filling amount is not uniform due to the deviation of the light source, and the durability against vibration impact is further increased.

  In particular, in the configuration shown in the fifteenth paragraph, the portion holding the reflecting mirror is the reflecting mirror bulging portion and is close to the bonding portion, so that the amount of gas used is small when blowing out the adhesive drying gas. In addition, since the process of fixing the disk to the seal portion of the light source and the process of fixing the disk to the reflecting mirror can be performed simultaneously, the number of manufacturing steps can be reduced.

In particular, in the configuration shown in the thirteenth paragraph, in order to create the light source position reference by melting the glass of the light source top part, the top part is reheated after the light source is sealed and exhausted to correct the position of the light source position reference. be able to.
After the light source is completed, it is easier to measure the actual optical center position by optical means and correct the light source position reference than other methods. And since the structure of the jig | tool used for an assembly is the simplest, cost is cheap, and it is advantageous when omitting the temporary drying process in a manufacturing process and arranging it to this drying furnace with the jig. Furthermore, since the structure of the jig used for assembly is the simplest, there is an advantage that even if heating and cooling are repeated, such as putting it in the main drying furnace, the jig is distorted, and there is no problem in use.

  Hereinafter, preferred embodiments of the present invention will be described. In focusing the light source and the reflecting mirror, the main focus of the present invention is to accurately align the center of the light source and the focal position of the reflecting mirror (particularly the relative position in the optical axis direction) without turning on the light source. . In the description of each embodiment, the optical axis direction is defined as the z-axis as necessary.

A manufacturing method including the process may be used.
(A) Setting of First Reference for Light Source Position A light source position reference serving as a reference for the optical center position 2 is provided somewhere on the outer surface of the light source 10.
(B) Setting of the first reference position of the reflecting mirror The reflecting mirror position reference serving as the reference for the position of the reflecting mirror focal point 12 is set on a plane perpendicular to the optical axis provided in the reflecting mirror bulging portion 18 or the opening of the reflecting mirror 11.

At the same time, the maximum outer diameter portion of the positioning member 7 is held in the side wall formed between the end face of the light source holding member 32 and the spot facing surface 36, and the central axis of the light source 10 and the central axis of the positioning member 7 coincide with each other. Can be made. By holding the light source perpendicular to the spot facing surface 36 by a light source chuck (not shown), the positional accuracy can be further improved.

  In the drawing, the dimension LC from the light source position reference 9 to the spot facing surface is determined in consideration of workability in the subsequent process, and the reflector cutting position for determining the dimension LH shown in FIG. You may design to arbitrary dimensions within the range settled in a position.

  Since the thickness t of the LC and the positioning member 7 is constant, the dimension LB from the optical center side end surface of the positioning member 7 to the optical center 2 is constant, and the feeder line side end surface of the positioning member 7 is the light source position second reference 35. It becomes.

The outer peripheral shape of the positioning member 7 is the same as the hole shape of the reflecting mirror 11 inserted when attached to the reflecting mirror 11 as shown in FIG. Further, the inner shape is the same as the shape after the tare 4 is sealed, and has a dimension that allows a slight gap when inserted into the seal portion 1.
When the positioning member 7 is manufactured from a metal plate, an adhesive is not used by providing the positioning member 7 with a nail shape that holds the seal portion 1 when the light source 10 is inserted into the positioning member 7. In both cases, the position of the positioning member can be temporarily fixed.
As disclosed in Patent Document 2, a protrusion may be provided on the seal portion 1 of the light source 10 so that the positioning member 7 stops at a fixed position.

FIG. 9 is a partial cross-sectional view showing an example of a method for cutting a reflecting mirror combined with a light source.
The position of the reflecting mirror 11 is fixed by bringing the reflecting mirror position reference 15 into contact with the tip surface of the reflecting mirror positioning member 142 fixed to one side of the jig B40.
A slide base 145 is provided on the other side of the jig B40, and the thin blade grindstone 148 attached to the motor 147 installed on the slide plate 146 moves downward in FIG. The end can be cut in a direction perpendicular to the central axis of the reflector.
In the figure, the LE dimension is the distance from the reflector position reference 15 to the reflector focus 12, and the dimension is determined at the time of designing the reflector. The LF dimension can be arbitrarily set within a practical range in consideration of workability.
The dimension of the LH portion needs to be the same value as the LB dimension in FIG. In order to satisfy the condition, the LG dimension for determining the cutting point from the positional relationship shown in FIG. 4 is set to LG = LF + LH−LE = LF + LB−LE.
Set to.

FIG. 10 is an explanatory diagram of a process of bonding and fixing a light source and a reflecting mirror in combination.
The jig C60 is for supporting the reflecting mirror 11 with its central axis kept vertical, and may be a flat plate that does not tilt the reflecting mirror. Further, it is necessary to provide a relief hole so that a part of the light source 10 protruding from the reflecting mirror 11 does not hit the jig C60.
The method of supporting the reflecting mirror 11 vertically is not limited to the method of the jig C60, and any part of the outer surface of the reflecting mirror may be used.

(E) In the state of the previous item, as shown in FIG. 10, the reflector adhesive 106 is filled and 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.

  The inclination regulating tube 37 is attached perpendicularly to the reflecting mirror position second reference 34. In this embodiment, since more than half of the total length of the light source 10 is accommodated in the inclination regulating tube 37, the light source 10 is held perpendicular to the second reference position 34 of the reflector position, and the optical axis of the reflector 11 is reflected. Since it is perpendicular to the plane of the mirror position reference 15, the central axis of the light source coincides with the optical axis of the reflecting mirror.

In the drawing, the position indicated by the multiplication symbol at the center of the reflecting mirror 11 is the reflecting mirror focal point 12. A front glass 13 for controlling light distribution is provided on the light irradiation side of the reflecting mirror 11, and a base 14 for supplying power is provided on the opposite side.
In order for such a lamp with a reflector to perform as designed, the light center 2 and the reflector focal point 12 must be in a position where the light source 10 and the reflector 11 are bonded and fixed. Don't be.

In order to make the optical center 2 and the reflector focus 12 coincide with each other without turning on the light source 10, manufacturing including the following two position reference settings and fixing and bonding steps using the position reference: A method may be used.

While maintaining the positional relationship, the two are bonded and fixed using a jig that can be filled with an adhesive in the bonding portion between them.
An example of a specific alignment method will be described below with reference to the drawings.

Example 3 FIG.
FIG. 12 illustrates the manufacturing method of the third embodiment of the present invention using a partial cross-sectional view.
FIG. 12A is a diagram for explaining a part of the process of creating the light source 10. The light emitting tube 3 and the support / feeding member 5 are inserted into the tare 4, and the tare lower opening is heated and sealed to create the light source 10. One end of the tare 4 is sealed with a pinch seal to form a seal portion 1. In the figure, the position indicated by the black circle symbol at the center of the arc tube 3 is the optical center 2 of the light source 10.

  In the heat sealing step, light source processing is performed so that the dimension LD from the shoulder portion of the tare 4 to the optical center 2 falls within the tolerance. In order to implement this, for example, as shown in FIG. 12A, the lamp member including the arc tube 3 is placed in the tare 4 by abutting the tip of the arc tube support member 5 against the inner wall of the arc tube shoulder. Try to be inserted at a certain position. The shoulder portion of the tare 4 becomes the light source position reference 9 of the light source 10 by the above method. The shoulder portion is an outer surface portion near the tip of the tare 4 and does not include the side surface of the tare 4 and is a portion away from the optical axis by a predetermined distance. That is, when the outer diameter of the tare is R and the distance from the z-axis is d, the outer surface portion near the tip of the tare 4 and the portion where 0 <d <R is the shoulder portion.

FIG. 12B is an explanatory view showing a state in which the leakage preventing member 70 is attached to the light source 10. The outer peripheral shape of the adhesive leakage preventing member 70 is the same as the hole shape of the reflecting mirror 11 inserted when attached to the reflecting mirror 11 as shown in FIG. To do. Further, the inner shape is the same as the shape after the tare 4 is sealed, and has a size that allows a slight gap when inserted into the seal portion 1 of the light source.
When the leakage prevention member 70 is made of a metal plate, by providing the leakage prevention member 70 with a claw shape that holds the seal portion 1 of the light source 10 when the light source 10 is inserted into the leakage prevention member 70, The position of the leak-proof member can be temporarily fixed without using an adhesive. As disclosed in Patent Document 2, a protrusion may be provided on the seal portion 1 of the light source 4 so that the leakage preventing member 70 stops at a certain position. Note that the position at which the leakage preventing member 70 should be fixed may not be a strictly determined position as long as it is constant.

FIG. 12C is a diagram for explaining a state when the light source 10 and the reflecting mirror 11 are set on the jig A21. The jig A 21 has a light source reference receiver 28 and a reflector reference receiver 29. When the dimension from the optical center 2 to the light source position reference 9 is LA, and the dimension from the reflector focus 12 to the reflector position reference 15 is LE, the height of the light source reference receiver 28 is higher than the height of the reflector reference receiver 29. Thus, there is a difference between LA and LE, and a difference corresponding to the value of LA-LE. When the dimension of LA is larger than LE, the height of the light source reference receiver 28 is lower than the height 29 of the reflector reference receiver.
In addition, under the above positional relationship, the jig A21 has a recess that allows the tip portion (head) of the tare to escape while the shoulder portion of the tare 4 is supported by the light source bearing 28 (through the through hole). May be). The reflecting mirror reference receiver 29 has a convex shape with respect to its periphery so as to support the reflecting mirror position reference 15 and not to contact other portions. That is, the jig A21 only needs to have a shape that supports only the light source position reference 9 (shoulder portion) and the reflector position reference 15, and does not contact the other portions of the light source and the reflector.

When the light source 10 and the reflecting mirror 11 are set on the jig A21, the optical center 2 and the reflecting mirror focus 12 overlap at the same position. Specifically, the inclination regulating tube 22 is attached perpendicularly to the surface formed by the reflector reference receiver 29 of the jig A21. When the jig A 21 and the tilt regulating tube 22 are viewed from above the z axis, the center of the tilt regulating tube 22 coincides with the center of the reflector reference receiver 29, and the inner diameter of the tilt regulating tube 22 is the outer diameter of the tare 4. It is almost the same. It should be noted that neither the tilt restricting tube 22 nor the anti-mirror reference receiver 29 needs to be completely circular (annular) when viewed from above the z axis, but they are installed concentrically with each other. And about the height of the inclination control tube 22 in the z-axis direction, it is sufficient that more than half of the total length of the light source 10 is within the inclination control tube 22. As a result, the light source 10 is held perpendicular to the reflector reference receiver 29 and the optical axis of the reflector 11 is perpendicular to the plane of the reflector position reference 15. The axes match.
FIG. 12D shows a state where the focusing operation is finished.

The manufacturing method in this example is as follows.
(A) The light source 10 is created so that the lamp shoulder is the light source position reference 9.
(B) The leakage preventing member 70 is inserted into the seal portion 1 of the light source 10 and attached.
(C) The light source 10 is mounted so that the light source position reference 9 is in contact with the light source reference receiver 28 of the jig A 21, and the reflector 11 is mounted so that the reflector position reference 15 is in contact with the reflector reference receiver 29.
(D) In this state, as shown in FIG. 12D, the reflecting mirror adhesive 106 is filled and 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.

  Although this embodiment is mainly applicable to a reflector having a simple circular center hole, if the reflector 11 having a bulged portion center hole 19 as shown in FIG.

As shown in the item (b), the reflector-equipped lamp can be manufactured without attaching the leakage preventing member 70. In addition, since the shape of the center hole 19 of the bulging portion is rectangular and is close to the shape of the seal portion 1 inserted therein, and no large gap is generated between them, the adhesive leaks even if the leakage preventing member 70 is not attached. There is no.

Example 4
FIG. 13 illustrates the manufacturing method of the fourth embodiment of the present invention using a partial cross-sectional view.
FIG. 13A is a diagram for explaining a part of the process of creating 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 G8.5 specification lamp, the dimension to the optical center is determined with reference to the tips of the pair of feeders 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.

FIG. 13B is an explanatory view showing a state in which the leakage preventing member 70 is attached to the seal portion 1 of the light source 10. The jig B31 has a light source reference receiver 33 and a cylinder 32.
When the light source position reference 9 of the light source 10 is brought into contact with the light source reference receiver 33, the leakage preventing member 70 is stabilized in a state of being in contact with the end face of the cylinder 32. In the figure, the height LC of the cylinder 32 is a range in which the leakage preventing member 70 is in an appropriate position for joining the light source 10 and the reflecting mirror 11 when the light source 10 is combined with the reflecting mirror 11 as shown in FIG. Inside, you may design to arbitrary dimensions. That is, the leakage preventing member 70 may be attached to the light source 10 perpendicularly to the optical axis with a constant LC.

  Since the thickness t of the LC and the leakage prevention member 70 is constant, the dimension LB from the optical center side end surface of the leakage prevention member 70 to the optical center 2 is constant, and the optical center side end surface of the leakage prevention member 70 is located at the light source position. 2 standard 35.

  FIG. 13C is a diagram for explaining a state when the light source 10 and the reflecting mirror 11 are set on the jig C36. The jig C36 has a light source reference receiver 38 and a reflector reference receiver 39. The dimension LF from the light source reference receiver 38 to the reflector reference receiver 39 is designed as follows.

If the dimension from the light source position reference 9 to the optical center 2 is LA and the thickness of the leakage preventing member 70 is t, the LB dimension in FIG.
LB = LA-LC-t
It becomes.
When the light source 10 and the reflecting mirror 11 are set on the jig C36 and the optical center 2 and the reflecting mirror focal point 12 coincide,
LF = LE + LB
That is,
LF = LE + LA-LC-t
Since the LE, LC, and t dimensions are determined by the product specifications, the LF dimension of the jig C is determined when the LA dimension of the jig B30 is set.

The manufacturing method in this embodiment using these jigs is as follows.
(A) The light source 10 is manufactured in the same manner as a normal G8.5 specification lamp.
(B) A leakage preventing member is passed through the seal portion 1 of the light source 10 and attached to the jig B31. The light leakage position reference 9 is temporarily fixed in a state where the light source position reference 9 is in contact with the light source reference receiver 33 of the jig B31 and the lower end surface of the leakage prevention member 70 is in contact with the upper end surface of the cylinder 32.
(C) The light source 10 and the reflecting mirror 11 are attached to the jig C36. The light source reference receiver 38 of the jig C36 and the light source position second reference 35 of the light source 10 are in contact, and at the same time, the reflector reference receiver 39 and the reflector position reference 15 are in contact. The shoulder portion of the light source 10 and the jig C are not in contact.
(D) In the state of the previous item, as shown in FIG. 13D, the reflector adhesive 106 is filled and dried.

Embodiment 5 FIG.
FIG. 14 shows a fifth embodiment of the present invention.
FIGS. 14A and 14B are diagrams for explaining a part of the process of creating the light source 10, and this part is the same as that of the fourth embodiment.

FIG. 14C is a diagram for explaining a state when the light source 10 and the reflecting mirror 11 are set on the jig D41. The reflecting mirror 11 has a shape as shown in FIG. 15, and has a square hole in a part of the bulging portion center hole 19 inside the reflecting mirror bulging portion 18.
The jig D41 has a light source reference receiver 48 and a reflector reference receiver 49. The reflector reference receiver 49 has a convex shape with respect to the periphery thereof so as to support the reflector position reference 15 and not to contact other portions. The stopper 45 is fixed to the jig D in the z-axis direction by the support 44. The slide plate 46 is slidable in the height direction and can also be rotated about the support column 44 as a central axis. Further, the slide plate 46 may be movable forward or backward in the drawing with respect to the support 44, or may be moved or stretched in the horizontal direction of the drawing. That is, when the light source 10 is set on the tilt regulating tube 42 from above the reflecting mirror 11 with the reflecting mirror 11 placed on the jig D41, the light source bearing 48, which is a part of the slide plate 46, is seen from the upper part of the reflecting mirror. It only needs to be able to escape. After the light source 10 is set, the height of the light source reference receiver 48 can be set to a constant value by lowering the slide plate 46 and bringing it into contact with the stopper 45.

The dimension LJ from the reflector reference receiver 49 to the top surface of the stopper 45 is LJ = LE + LA
And If the design is made in this way and the slide plate shape has no step between the light source reference receiver 48 and the stopper contact portion, the dimension from the reflector reference receiver 49 to the light source reference receiver 48 is also LJ, and the optical center 2 and the reflection The position of the mirror focus 12 can be matched.

  In the slide plate 46, a step may be provided between the light source reference receiver 48 and the stopper contact portion. However, the dimension from the reflector reference receiver 49 to the upper surface of the stopper 45 is a value obtained by adding or subtracting the step to LJ. It is necessary to adjust the stopper position.

  In the jig D41, a notch is provided in a part of the inclination regulating tube 42 to expose the inner surface of the inclination regulating tube, and a ring-shaped spring 43 is applied to the notch. The light source 10 inserted into the tilt regulating tube 42 is pressed against the inner surface of the tilt regulating tube opposite to the notch by the spring 43 and fixed in position. However, when an external force exceeding the gravity is applied, the center axis method can be moved.

The manufacturing method in this example is as follows.
(A) As shown in FIGS. 14A and 14B, the light source 10 is manufactured in the same manner as a normal G8.5 specification lamp.
(B) As shown in FIG. 14C, the light source 10 and the reflecting mirror 11 are attached to the jig D41. The reflector reference receiver 49 of the jig D41 and the reflector position reference 15 are in contact with each other. At this time, the slide plate 46 is retracted so as not to obstruct the light source 10 and the reflector 11 attachment. 48 and the light source position reference 9 of the light source 10 are not in contact with each other.
(C) As shown in FIG. 14D, the slide plate 46 is brought into contact with the stopper 45, and the light source reference receiver 48 is brought into contact with the light source position reference 9. The dimension from the reflector reference receiver 49 to the light source reference receiver 48 is LJ, and the positions of the optical center 2 and the reflector focus 12 coincide.
(D) Fill the reflector adhesive 106 in the state of the previous paragraph and dry.

  In the case where the viscosity of the reflective mirror adhesive 106 is low and the reflective mirror adhesive 106 flows to the optical center 2 side of the light source 10, as shown in FIG. 14 (d), gas is applied to the substrate of the jig D41. Open the hole to be circulated, and pass from the jig through the reflecting surface side of the reflector and the bonding part at least from the time immediately before filling the adhesive to the time when the adhesive is dried and the reflector and the light source are temporarily fixed. It is good to distribute gas. The adhesive can be prevented from flowing out and the drying time can be shortened.

  Alternatively, the leakage preventing member 70 used in the third embodiment can also be used. In this case, the center hole of the reflecting mirror may be a simple circle.

  Also in this embodiment, since more than half of the total length of the light source 10 is accommodated in the inclination regulating tube 42, the light source 10 is held perpendicular to the reflector reference receiver 49, and the optical axis of the reflector 11 is the reflector position. Since it is perpendicular to the surface of the reference 15, the central axis of the light source and the optical axis of the reflecting mirror coincide.

  The tilt regulating tube does not need to have a cylindrical shape, and a V-shaped holding member may be used to hold the tilt regulating tube perpendicular to the reflector reference receiver. The method of holding the light source is not limited to the ring-shaped spring, and there are many methods such as rubber, a leaf spring, and a ball plunger for obtaining the same effect.

  In the above embodiments, the present invention has been described with respect to a built-in discharge lamp arc tube as a light source. However, the same effect can be obtained even when an incandescent lamp such as a single-ended halogen lamp having a similar shape is used as a light source. Can be obtained.

Example 6
FIG. 16 is a view showing a sixth embodiment of the present invention, and FIG. 17 is a partial sectional view showing an example of a disk shape according to the present invention. In FIG. 17, the φDD dimension is about 0.1 to 2 mm smaller than the diameter of the reflector center hole, and the φDF dimension is conversely about 0.1 to 2 mm larger than the diameter of the reflector center hole. A dimension smaller than the outer diameter of the end face is desirable.

The manufacturing method in the present embodiment using these members and jigs is as follows.
As shown in FIG. 16A, 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. Also in the G8.5 lamp, it is necessary to make the distance LA from the end of the feeder 6 to the optical center 2 constant because of the specification, and the G8.5 lamp can be used as it is as the light source for the lamp with a reflector of the present invention. Is possible. After completion of the light source, the end of the feeder 6 becomes the light source position reference 9 as shown in FIG.

  As shown in FIG. 16 (c), 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.

  The reflecting mirror 11 is placed 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 end face of the reflecting mirror reference receiver 49 is circular and the cross-section orthogonal to the central axis of the reflecting mirror is also circular, the reflecting mirror focal point 12 is on the alignment axis 51 that substantially coincides with the central axis of the reflecting mirror reference receiver 49.

  A disc 100 having a shape as shown in FIG. 17 is inserted into the seal portion 1 of the light source 10. The disk 100 is pushed in until the flange portion of the disk 100 hits the end face of the reflecting mirror 11.

  As shown in FIG. 16 (d), 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 to the optical center and the distance LE from the reflector position reference 15 to the reflector focal point 12, The positions of the center 2 and the reflector focus 12 coincide.

  In the state of the previous paragraph, the reflecting mirror adhesive 106 is filled between the disk 100 and the light source 10 and between the disk 100 and the reflecting mirror 11 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.

The light source with a reflecting mirror after temporary drying is removed from the jig, and several to several hundreds are put together in a drying furnace (not shown) to completely dry the adhesive.
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.

Example 7
FIG. 18 is a partial cross-sectional view showing an example of manufacturing a lamp with a reflector according to the present invention. In FIG. 18, reference numeral 23 denotes a jig A used for focusing a lamp with a reflector, and a light source reference receiver 28 provided in the center portion is LA-LE relative to a reflector reference receiver 29 provided in the periphery thereof. Only the dimension corresponding to the value is lowered.

  In this embodiment, a disk having the same shape as in FIG. 17 is used. Conversely, the φDF dimension is preferably about 0.1 to 2 mm larger than the diameter of the reflector center hole and smaller than the outer diameter of the end face of the reflector bulge.

The manufacturing method in the present embodiment using these members and jigs is as follows.
As shown in FIG. 18 (a), a mount in which a light source constituting member such as the arc tube 3 support member 5 is joined in advance is inserted into the tare 4, and one end of the tare 4 is sealed with a pinch seal. It is stopped and the seal part 1 is formed.

  At the end of the exhaust process performed after sealing the light source, the exhaust pipe of the light source top part is formed so that the distance LA from the light source top part end surface to the light center 2 is constant and the light source central axis and the light source top part end surface are perpendicular. The light source 10 is manufactured. After completion of the light source, the end surface of the light source top portion becomes the light source position reference 9 as shown in FIG. Note that the shape of the light source position reference is not limited to the shape shown in the figure. For example, even if the light source top end portion is formed in a hemispherical shape, it may be used as long as the LA dimension can be formed to a constant value.

  As shown in FIG. 18 (c), the light source 10 is inserted into the tilt regulating tube 22. The light source 10 slides down in the inclination regulating tube 22 by its own weight, and stops when the light source position reference 9 contacts the light source reference receiver 28 of the jig A23.

  The reflecting mirror 11 is placed on the jig A 23 from above the light source 10. At this time, the reflector position reference 15 is set so as to contact the reflector reference receiver 29. At this time, the height of the light source reference receiver 28 is different from the height of the reflector reference receiver 29 by a difference between LA and LE, and a difference corresponding to the value of LA-LE. The position with the mirror focus 12 coincides.

  The disk 100 described above is inserted into the seal portion 1 of the light source 10. The disk 100 is pushed in until the flange portion of the disk 100 hits the end face of the reflecting mirror 11.

  In the state of the previous paragraph, the light source adhesive 105 and the reflective mirror adhesive 106 are filled between the disk 100 and the light source 10 and between the disk 100 and the reflective mirror 11 and temporarily dried.

  The light source with a reflecting mirror after temporary drying is removed from the jig, and several to several hundreds are put together in a main drying furnace (not shown) to completely dry the adhesive. At this time, temporary drying may be omitted or rounded up in a short time, and the jig may be put into the main drying furnace.

  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 above embodiment, some of the most suitable ones are shown. For example, the reflector position reference, the light source position reference, each attachment member, a combination of jigs, the attachment plate, the leakage prevention member, the presence or absence of the disk, etc. It can be selected as appropriate.
