FIG. 7 is an external view showing the lid portion 90 and the outer edge projecting portion 91 in the first embodiment.
FIG. 8 is an assembly external view showing the lid 90 and the substrate 61 in the first embodiment.

The lid portion 90 is a flat plate that covers the cylinder end portion 86 of the substrate 61.
The area of the lid portion 90 is larger than the cross-sectional area of the cross-sectional shape orthogonal to the cylindrical axis Z of the tubular portion 63, and the lid portion 90 is a polygonal aluminum flat plate having a shape similar to the cross-sectional shape of the tubular portion 63. .. Here, since the cross-sectional shape of the tubular portion 63 is a regular dodecagon, the lid portion 90 is also a regular dodecagonal aluminum flat plate. The lid portion 90 may be a circular flat plate covering a cross-sectional shape orthogonal to the cylindrical axis Z of the tubular portion 63.
The lid portion 90 is fixed to the substrate so as to cover the entire cylinder end portion 86 of the substrate 61 and away from the cylinder end portion 86 of the substrate in the cylinder axis Z direction.
The lid portion 90 completely covers the cross-sectional shape of the tubular portion 63 in the Z direction of the cylindrical shaft, and has an outer edge projecting portion 91 protruding outward from the cylindrical end portion 86 of the tubular portion 63. ..

The diagonal length of the outer edge projecting portion 91 (or the diameter in the case of the circular lid portion 90) is the same as the inner diameter of the cover 71. Alternatively, the manufacturing variation B (0.5 mm) in the radial direction of the cover 71 is smaller in the radial direction from the central axis C of the cover 71.
The outer edge projecting portion 91 projects outward from the outer surface 84 of the tubular portion 63.
The outer edge projecting portion 91 is an example of the projecting portion 80 that guides the insertion of the light source unit 60 into the cover 71.

As shown in FIG. 8, the protruding height W2 of the outer edge projecting portion 91 is preferably set higher than the height W1 of the light source 65 and the electronic component of the cylindrical portion 63. For example, in a state where the central axis C of the cover 71 and the central axis Z of the light source unit 60 are aligned with each other, the protruding height W2 of the outer edge projecting portion 91 is the height W3 (the outer surface 84 and the outer surface 84) to the inner wall of the cover 71. It is smaller than the distance from the inner wall) and 0.5 mm higher than the maximum height W1 of the electronic component.

The relationship between the heights of the cover 71 as seen in the radial direction from the cylinder axis Z is as follows.
Radius R of the inner wall of the cover 71> Protruding height of the outer edge projecting portion 91> Maximum height of the electronic component> Outer surface 84 of the tubular portion 63
W3 = W2 + manufacturing variation B
W2 = W1 + 0.5mm
In addition, W1 = W2 may be set.

By providing the outer edge projecting portion 91, it is possible to avoid direct contact between the lens tip portion of the LED and the inner wall surface of the cover 71. Further, the light source unit 60 can be stably inserted into the cover 71 by the outer edge projecting portion 91 (protruding portion 80) without depending on the height dimension of the LED package, and can be stored without tilting. can do.
The outer edge projecting portion 91 has a function of positioning the light source unit 60 at the center of the cover 71 from the middle of inserting the light source unit 60 into the cover 71. If the manufacturing variation B is zero, theoretically, W3 = W2 can be set, and in the outer edge projecting portion 91 of the lid portion 90, the central axis C of the cover 71 and the central axis Z of the light source unit 60 are aligned. Exact match.

As described above, the outer edge projecting portion 91 has a function of aligning the central axis C of the cover 71 with the central axis Z of the light source unit 60 when the lid portion 90 is inserted into the cover 71. Therefore, when the light source unit 60 is inserted into the cover 71, the light source unit 60 can be inserted in the cover 71 without being greatly tilted, and can be stored without being further tilted.

The assembly dimensions of the board 61 are the distance between the tip of the light source or electronic component and the inner wall surface of the cover 71 in a state where the board 61 is stored (inserted) without tilting to the cover 71 in an environment at room temperature. Secure about 0.5 mm for K1 (W3-W1). That is, with the central axis C of the cover 71 and the central axis Z of the light source unit 60 aligned, the interval K1 is secured to be about 0.5 mm (K1 = W3-W1 = 0.5 mm).
Further, the distance K2 (W3-W2) between the maximum outer diameter end of the lid 90 and the inner wall surface of the cover 71 is such that the manufacturing variation B (about 0.5 mm) or more is close to the manufacturing variation B. do. That is, with the central axis C of the cover 71 and the central axis Z of the light source unit 60 aligned, the interval K2 is set to about 0.5 mm (K2 = W3-W2 = 0.5 mm).

There is no problem if the tip of the light source or electronic component comes into contact with the inner wall surface of the cover 71, but it is desirable not to apply mechanical pressure or stress to the light source or electronic component. Therefore, in order to prevent the tip of the light source or the electronic component from coming into contact with the inner wall surface of the cover 71, it is preferable to set the interval K1> the interval K2.
When the interval K1 = interval K2, the tip of the light source or the electronic component may come into contact with the inner wall surface of the cover 71.
When the interval K1 <interval K2, the tip of the light source or electronic component comes into contact with the inner wall surface of the cover 71 before the maximum outer diameter end of the lid 90, causing mechanical pressure or stress on the light source or electronic component. Will be given.

The lamp mark 54 is printed on the surface (surface) of the lid 90 on the base side.
On the surface (surface) of the lid 90 on the base side, there is a lid support steel wire 98. The lid support steel wire 98 has a U shape, and both ends are welded to the lid portion 90. A support pillar 58 fixed to the stem 76 is welded to the center of the lid support steel wire 98, and the stem 76 and the lid portion 90 are fixed.

There is a fastener 95 on the surface (back surface) of the lid 90 on the light source unit 60 side.
The fastening metal fitting 95 is a C metal fitting obtained by bending a rectangular sheet metal having a short side length D into a C shape (U shape), and has a flat back plate and two fastening side portions 85 on both sides of the back plate. The back plate in the center of the fastener 95 is spot welded to the lid 90. The two fastening side portions 85 on both sides of the back plate have metal fitting screw holes 97, and the fastening side portions 85 are fixed to the substrate 61 by screws 96. Fastening members other than the screw 96, such as an adhesive or a fitting mechanism, may be used. By fixing the fastener 95 and the substrate 61, the lid 90 is fixed to the substrate 61.

As described above, since the lid support steel wire 98 and the support pillar 58 are welded together, the stem 76, the lid 90, and the substrate 61 are integrally formed, and the stem 76, the lid 90, and the substrate 61 form the light source unit 60. Will be done.

Around the lid 90, there is a pair of wide recesses 93 (an example of the recesses) in the 180-degree direction. The wide recess 93 is a rectangular cutout portion. The length of the long side of the wide recess 93 is the same as the length D of the short side (one side of the regular dodecagon) on the inner side surface of the tubular portion 63. The length of the short side of the wide recess 93 is a length that does not expose the internal space of the tubular portion 63 (projection height W or less in FIG. 8). That is, the wide recess 93 exists outside the outer surface 84 of the substrate. The wide recess 93 does not expose the internal space of the tubular portion 63 in the tubular axis Z direction.

Around the lid 90, there is a pair of arcuate recesses 94 (an example of the recesses). The arc-shaped recess 94 has a semicircular or U-shaped shape. The width and depth of the arc-shaped recess 94 may be large enough to allow the polyimide tube 79 to pass through. The depth of the arc-shaped recess 94 is set to a length that does not expose the internal space of the cylindrical portion 63 (projection height W or less in FIG. 8). That is, the arc-shaped recess 94 exists outside the outer surface 84 of the substrate. The arcuate recess 94 does not expose the internal space of the tubular portion 63 in the tubular axis Z direction.

The relationship between the lengths in the radial direction in which the electronic components are present when viewed from the center of the lid portion 90 (cylindrical axis Z of the tubular portion 63) is as follows.
Radius to the inner wall of the cover 71> Radial length of the outer edge projecting portion 91> Radial height of the electronic component> Outer surface 84 of the tubular portion 63
For example, as shown in FIG. 8, the outer edge projecting portion 91 projects outward from the outer surface 84 of the tubular portion 63 by a protrusion height W. The protrusion height W is the distance between one side of the outer edge projecting portion 91 and the outer surface 84 of the tubular portion 63 in a cross section orthogonal to the cylinder axis Z direction.
Except for the locations of the wide recess 93 and the arcuate recess 94, the lid 90 has an outer edge projecting portion 91 having a width of a protruding height W around it.

The lid 90 is assembled so that the distance between the base side end portion (cylinder end portion 86) of the substrate 61 is 1.5 mm or more.
The two wide recesses 93 have a function of a filling hole for filling silicone after the light source unit 60 is housed in the cover 71, and also function as a ventilation path between the substrate side and the base side of the lid 90. Have both.

The two arc-shaped recesses 94 are gaps through which the NIP iron wire 78 covered by the polyimide tube 79 is inserted. The NIP iron wire 78 electrically connects the stainless sleeve 77 of the stem 76 and the wiring pad 83 of the substrate 61.
Preferably, the two arcuate recesses 94 are provided at positions where the path of the NIP iron wire 78 is the shortest.

The two arcuate recesses 94 may be provided on the peripheral edge of the lid 90 in rotational symmetry.
The two wide recesses 93 and the two arcuate recesses 94 are structurally required by increasing the maximum outer diameter of the lid 90 so that the light source unit 60 does not tilt. That is, the arc-shaped recess 94 and the wide recess 93 secure a passage path for electric wires and silicone by narrowing the distance between the maximum outer diameter end of the lid 90 and the inner wall surface of the cover 71 to about 0.5 mm. It is a thing.

One end of the NIP iron wire 78 is spot welded to the stainless sleeve 77, and the other end is covered with the polyimide tube 79, passes through the arcuate recess 94 of the lid 90, and is soldered to the wiring pad 83.

The fastening metal fitting 95 is fixed to the tubular portion 63 by a screw 96. Since H1> = H2 + 1.5 mm, a lid gap 99 of 1.5 mm or more is formed between the end surface of the cylinder end portion 86 of the substrate 61 and the back surface of the lid portion 90. Since there is a lid gap 99, the inside of the cylinder of the substrate 61 is not sealed and the air permeability is maintained.

The short side length (short side length of the fastening metal fitting 95) of the fastening side portion 85 that stands up from the lid portion 90 when the fastening metal fitting 95 is bent has the same dimensions as the bending interval D (polygonal side length D) of the substrate 61. Is. Further, the short side length of the fastening side portion 85 (the short side length of the fastening metal fitting 95) is the same as the width of the wide recess 93. Therefore, the entire outer surface of the fastening side portion 85 abuts over the entire surface of the cylindrical end portion of the inner surface of the tubular portion 63 of the substrate 61. That is, both sides of the fastening side portion 85 are inserted linearly along the bent portion 62. Therefore, when the lid portion 90 is screwed to the substrate 61, the rotation of the lid portion 90 with the center of the metal fitting screw hole 97 of the fastener fitting 95 spot-welded to the lid portion 90 as a fulcrum can be restricted. The surface of the lid portion 90 is fixed to be exactly orthogonal to the tubular axis Z of the tubular portion 63 of the substrate 61.

It is assembled so that the distance between the lid 90 and the end on the base side of the substrate 61 is 1.5 mm or more. This interval is determined by the relative relationship between the position of the metal fitting screw hole 97 of the fastening metal fitting 95 and the position of the board screw hole 82 of the substrate 61, and can be arbitrarily set according to the design specifications.

FIG. 9 is a diagram showing a substrate projecting portion 81 according to the first embodiment.
The board projecting portion 81 is made by embossing an aluminum board (board 61) so as to project in a chevron shape from the surroundings. The zenith portion of the board projecting portion 81 has a curved surface so as not to damage the inner wall of the cover 71.
The board projecting portion 81 is located at the end of the outer surface 84 of the tubular portion 63 of the substrate 61 (the end on the conical portion 64 side), and projects toward the inner wall surface of the cover 71 (radial direction). There is.
The board projecting portion 81 is an example of a projecting portion that guides the insertion of the light source unit 60 into the cover 71.
The board projecting portion 81 is formed by partially projecting the board 61 while avoiding the LED mounting portion and the wiring pattern attachment portion.
The board projecting portion 81 is provided at three locations (for example, every 120 degrees) on the circumference at equal intervals in consideration of variations in the cover 71, the substrate 61, and the substrate projecting portion 81. As a result, the central axis C of the cover 71 and the central axis Z of the light source unit 60 can be aligned with each other. The board projecting portion 81 may be provided at four or more locations on the circumference at equal intervals in consideration of the inclination at the time of assembly or the displacement of the light source (LED) 65 due to vibration.

As shown in FIG. 10, the height T2 of the board projecting portion 81 is preferably set higher than the height T1 of the light source 65 of the tubular portion 63 and the electronic components. For example, with the central axis C of the cover 71 and the central axis Z of the light source unit 60 aligned, the height T2 of the board projecting portion 81 is the height T3 (outer surface 84 and inner wall) to the inner wall of the cover 71. It is smaller than (distance from) and 0.5 mm higher than the maximum height T1 of the electronic component.

The relationship between the heights of the cover 71 as seen in the radial direction from the cylinder axis Z is as follows.
Radius R of the inner wall of the cover 71> Height of the board projecting portion 81> Maximum height of the electronic component> Outer surface 84 of the tubular portion 63
T3 = T2 + manufacturing variation B
T2 = T1 + 0.5mm
In addition, T1 = T2 may be set.

By providing the board projecting portion 81, it is possible to avoid direct contact between the lens tip portion of the LED and the inner wall surface of the cover 71. Further, the light source unit 60 can be stably inserted into the cover 71 by the board projecting portion 81 (protruding portion 80) without depending on the height dimension of the LED package, and can be stored without tilting. can do.
When the light source unit 60 is inserted into the cover 71, it is possible to avoid mechanical stress on the LED such as disconnection in the LED package.
The board projecting portion 81 has a function of positioning the light source unit 60 at the center of the cover 71 from the initial insertion of the light source unit 60 into the cover 71. If the manufacturing variation B is zero, theoretically, T3 = T2 can be set, and the central axis C of the cover 71 and the central axis Z of the light source unit 60 are completely in the portion where the board projecting portion 81 is located. Matches.
The light source 65 may use an LED package having no lens.

After all, due to the presence of the outer edge projecting portion 91 of the lid portion 90 and the board projecting portion 81 of the substrate 61, the cover 71 is provided at two locations, the position where the outer edge projecting portion 91 is located and the position where the board projecting portion 81 is located. The central axis C of the light source unit 60 and the central axis Z of the light source unit 60 are completely aligned with each other. As a result, the central axis C of the cover 71 and the central axis Z of the light source unit 60 coincide with each other at all positions, and the light source unit 60 can be inserted into the cover 71 without tilting and can be stored without tilting. can. Even if a deviation occurs between the central axis C of the cover 71 and the central axis Z of the light source unit 60, the maximum deviation is within the range of the manufacturing variation B.

The board projecting portion 81 can be formed by partially projecting the board 61 by cutting and bending instead of embossing, avoiding the LED mounting portion and the wiring pattern attachment portion.
Alternatively, the board projecting portion 81 is formed by fixing a bell-shaped part or a dome-shaped part, which is a separate part from the board 61, to the tubular part 63 of the board 61 by a method such as adhesion or welding. You may.

FIG. 11 is a diagram showing the shape of the ventilation holes 66 formed in the substrate 61 in the first embodiment.
The shape of the ventilation hole 66 may be circular. It may be a quadrangle. It may be a long hole or a slit. The ventilation holes 66 may exist alone or may be present in a plurality of arrangements.
The ventilation hole 66 may be arranged on the outer surface 84 as long as it is a place other than the LED or the wiring pattern other than the bent portion 62.

FIG. 12 is a diagram showing an air path according to the first embodiment.
The lighting lamp 50 repeats expansion and contraction of the cover 71 and the air inside the cover 71 as the lighting state is repeated and the installation environment temperature rises and falls repeatedly.

As a result, the air is mounted on the external space of the lighting lamp 50 and the LED through the two recesses 74 near the base, the lid gap 99 between the lid 90 and the substrate 61, and the ventilation hole 66 of the substrate 61. It moves in the intake / exhaust direction with and from the internal space of the lighting lamp 50. The arrow in FIG. 12 indicates the intake direction, and the exhaust direction is vice versa.

Silicone 53 has good heat dissipation characteristics, but also has good gas permeability. For example, the gas permeability of silicone has the following values when natural rubber is 100.
Hydrogen: 1070
Oxygen: 2200
Nitrogen: 3300
Carbon dioxide: 1600
Air: 2700

Therefore, even if the light source 65 is covered with the silicone 53, air can propagate in the silicone and reach the light source 65. Here, it is desirable that the ventilation hole 66 is provided in the vicinity of the light source 65 because the air permeability is improved by shortening the distance in the silicone through which the air propagates.
If the size of the ventilation hole 66 is increased, when the silicone 53 is filled between the substrate 61 and the cover 71, the silicone 53 leaks into the internal space of the substrate 61 via the ventilation hole 66, so that the ventilation hole 66 The size of the hole is such that the silicone 53 does not pass through, for example, a hole having a diameter of about 1 mm at most. Alternatively, it is preferable to seal (caulk) the ventilation holes 66 with the silicone 53 before filling the silicone 53 to prevent the silicone 53 from leaking into the internal space of the substrate 61 from the ventilation holes 66.
It is preferable that the internal space of the substrate 61 is filled with air without the presence of the silicone 53, and the air is taken into the light source 65 from the ventilation holes 66 via the silicone 53.

Therefore, the internal space of the substrate 61 on which the LED is mounted is always filled with fresh air, and in addition to the effect of lowering the operating temperature of the LED, the effect of suppressing deterioration of the resin encapsulating material constituting the LED package with time is achieved. Play.

The air propagation path is summarized below.
Outside air-recess 74-cap gap 73-internal space of cap 72-tube port 57-chip tube 75-stem port 56-internal space of cover 71-cover gap 99-internal space of substrate 61-vent hole 66 of substrate 61- Silicone 53-light source 65

As described above, since a path through which air can flow is provided between the vicinity of the surface of the light emitting diode and the outside of the lighting lamp 50, deterioration of the optical properties of the encapsulating material constituting the LED package with time is suppressed. It is possible to maintain stable optical characteristics for a long period of time.

Hereinafter, a characteristic portion of the method for manufacturing the lighting lamp 50, particularly the method for filling silicone, will be described.

<<< Manufacturing method of substrate 61 >>>
The aluminum substrate on which the light source and circuit are mounted is bent with a special jig. After bending, it is fixed with a molding so that the substrate gap 55 is minimized. Then, the four soldering portions 67 on the mating surface of the board are soldered. The substrate gap 55 of the conical portion 64 is closed by applying masking tape from the surface.

Next, the gap of the substrate 61 is closed (sealed) so that the silicone 53 does not enter the internal space of the substrate 61. Specifically, after the substrate 61 is assembled and molded, the ventilation holes 66 and the substrate gap 55 are caulked (sealed) from the inside of the substrate 61 with a sealing silicone (for example, KE-1885) among Shinetsu silicone silicone rubbers. )do. Caulking is performed from the inside to the outside of the substrate 61 and along the bent portion 62 or the substrate gap 55. The substrate gap 55 of the cone 64 is also caulked. After caulking, the substrate 61 is dried in a constant temperature bath.

As a sealing material, the same silicone as the silicone 53 filled in the cover 71 or a breathable adhesive silicone may be applied to seal the cover 71, or a breathable sheet such as a porous film may be attached. May be good. The reason for sealing is to prevent the silicone 53 from being injected into the internal space of the substrate 61. When the silicone 53 is injected into the internal space of the substrate 61, the air propagation path of the silicone 53 becomes long, and it becomes difficult for the air to be supplied to the light source 65.

<<< Manufacturing method of lid 90 >>>
The lamp mark 54 is laser-printed on the lid 90.
The lid support steel wire 98 is fixed to the side surface (surface) of the base of the lid 90 with a special jig and spot welded.
The fastener 95 is fixed to the side surface (back surface) of the substrate of the lid 90 with a special jig and spot welded.
The lamp mark 54 may be engraved on the lid portion 90, or the displayed sheet or plate may be adhered to the lid portion 90.

<<< Manufacturing method of light source unit 60 >>>
The fastening side portion 85 of the fastener portion 95 is inserted into the inner surface of the substrate 61, the screw 96 is passed through the bracket screw hole 97 and the substrate screw hole 82, and the distance between the back surface of the lid portion 90 and the end surface portion of the end surface portion of the substrate 61 is 1. Fix it so that it is 5.5 mm or more.
The NIP iron wire 78 is passed through the polyimide tube 79 so that the NIP iron wire 78 and the lid 90 do not come into electrical contact with each other.
The NIP iron wire 78 is fitted into the position of the arcuate recess 94.
One end of the NIP iron wire 78 is soldered to the wiring pad 83 of the substrate 61.
The lid support steel wire 98 and the support column 58 are spot welded.
The other end of the NIP iron wire 78 is spot welded to the stainless sleeve 77.
The lead wire 59 is spot welded to the stainless sleeve 77.
At this point, the light source unit 60 is completed.

<<< Silicone 53 injection method >>>
The light source unit 60 is inserted into the cover 71 whose one end is open, and the open portion of the cover 71 and the end portion of the stem 76 are melted and coupled.
As shown in FIG. 13, the injection needle (nozzle for adjusting) of the silicone dispenser is inserted into the pipe opening 57 of the tip tube 75, and the silicone 53 extruded from the silicone dispenser is injected into the cover 71. At this time, the injection needle of the dispenser is inserted with the opening of the tip tube 75 facing upward. That is, the side to which the base 72 is attached is arranged upward, and the silicone 53 is hung from the tip of the injection needle by gravity and injected. The cover 71 has a pipe axis C with respect to the vertical direction so that one wide recess 93 is diagonally downward (lower left in FIG. 13) and the other wide recess 93 is diagonally upward (upper right in FIG. 13). Is tilted by θ degrees (eg, 20 to 30 degrees).

As the silicone 53, for example, a mixture of KE-109E-A and KE-109E-B, which are silicone rubbers made of Shin-Etsu Silicone, at a predetermined mixing ratio (for example, a mixing ratio of 2: 1) is suitable. The silicone 53 is not limited to the two-component type, but may be a one-component type.
When the silicone 53 is injected, the silicone 53 drops on the surface of the lid 90. Since the lid 90 is tilted by θ degree, the 53 flows to the lower left and falls from the wide recess 93 on the lower left between the outer surface of the substrate 61 and the inner wall surface of the cover 71. Since the lid 90 covers the substrate 61, the silicone 53 does not enter the inside of the substrate 61.
At the same time as the injection of the silicone 53, only the volume of the injected silicone 53 causes the air in the cover 71 to pass through the wide recess 93 on the upper right and to the outside through the gap between the injection needle 230 and the inner surface of the tip tube 75. leak.

Since the silicone 53 is for heat dissipation of the light source, it may be filled up to the height where the portion where the light source is arranged exists. When the silicone 53 is injected up to the cylinder end portion 86 of the substrate 61, the lid gap 99 is closed and the air permeability is lost. Therefore, the silicone 53 has a height higher than the height covering all the light sources 65 and less than the cylinder end portion 86. Inject until now. For example, the silicone 53 is injected to a position of about 10 mm from the end face of the cylinder end portion 86.

<<< With a clasp >>>
After filling the silicone 53, the tip tube 75 is chip-cut.
After that, the base 72 is attached, and the two lead wires 59 are soldered to the base 72.
The lead wire on the − side of the board 61 is wired in the base gap 73 and soldered to the base side by the recess 74 of the cover 71.
The lead wire on the + side of the board 61 is soldered to the eyelet side.

It can be stored while maintaining a state orthogonal to the relative.
In order to reduce the friction between the contact surface and the inner wall surface when the light source unit 60 is inserted into the cover 71, a member that promotes slippage may be attached to the contact surface.

The tongue-shaped protruding portion 92 of FIG. 17 is not located at a position corresponding to the bent portion 62, but is located at a position corresponding to the center of the outer surface 84 of the substrate 61.

After all, the central axis C of the cover 71 and the central axis Z of the light source unit 60 coincide with each other at all positions. Therefore, the light source unit 60 can be inserted into the cover 71 without tilting, and can be stored without tilting. If the board projecting portion 81 is provided at two locations in the cylinder axis Z direction, the outer edge projecting portion 91 may not be provided.

The mounting hole 611 is formed in a place where the light source 65 and the electronic component are not mounted. Further, the mounting hole 611 is formed in a place where the circuit pattern is not laid.
FIG. 24 shows an example in which a mounting hole 611 is formed in a portion of the upper part of the aluminum substrate where the light source 65 does not exist.
The mounting hole 611 can be formed at the same time as the formation of the ventilation hole 66 and the substrate screw hole 82 by the same processing as the ventilation hole 66 and the substrate screw hole 82 shown in FIG. 24.

Next, the light source and the circuit are mounted on the aluminum substrate.
On the contrary, the mounting hole 611 may be formed after the light source and the circuit are mounted on the aluminum substrate.

Next, the mounting hole 611 is formed, and the aluminum substrate (board 61) on which the light source and the circuit are mounted is bent by a special jig.
After that, it is the same as the manufacturing method of the substrate 61 described in the first embodiment.

<Step S12: Manufacturing method of lid 90>
It is the same as the manufacturing method of the lid portion 90 described in the first embodiment.

<Step S13: Manufacturing method of the light source unit 60>
It is the same as the manufacturing method of the light source unit 60 described in the first embodiment.
The elastic member (peripheral spacer) 810 is a separate component from the light source unit 60, and after the light source unit 60 is completed, the elastic member (peripheral spacer) 810 is fitted into the mounting hole 611.
At that time, the elastic spacer mounting portion 814 is manually deformed to pass through the mounting hole 611.
Then, the mounting holes 611 are arranged all around the neck portion 8192 of the connecting portion 819.
By engaging the elastic member (peripheral spacer) 810 with the mounting hole 611 in this way, the elastic member (peripheral spacer) 810 is mounted so as not to come off the substrate 61.

<Step S14: Insertion of the light source unit 60>
The light source unit 60 is inserted into the cover 71 whose one end is open.
Specifically, while holding the outer wall surface 710 of the cover 71, the light source unit 60 is inserted into the center of the inner wall surface 711 of the cover 71 with the conical portion 64 at the head.
The elastic member (peripheral spacer) 810 slides while contacting the inner wall surface 711 of the cover 71.
When the slide is moved, the head T of the elastic member (peripheral spacer) 810 moves without being deformed or slightly deformed and dented.
When the light source unit 60 is arranged on the cover 71, the head T of the elastic member (peripheral spacer) 810 hits the inner wall surface 711 of the cover 71, so that the light source 65 does not hit the inner wall surface 711 of the cover 71.
That is, the elastic member (peripheral spacer) 810 can prevent the LED lens tip from coming into direct contact with the inner wall surface 711 of the cover 71.
Further, the elastic member (peripheral spacer) 810 allows the light source unit 60 to be stably inserted into the cover 71 without tilting, and can be stored without tilting.
As described above, the elastic member (peripheral spacer) 810 can reliably maintain the posture of the light source unit 60 arranged in the cover 71 while the illumination lamp 50 is in the process of being assembled.
After inserting the light source unit 60 into the cover 71, the open portion of the cover 71 and the end portion of the stem 76 are melted and coupled.

<Step S15: Attaching a base>
It is the same as the clasp attachment described in the first embodiment.
This completes the lighting lamp 50 in which the cover 71 is not filled with the silicone resin.
In the completed lighting lamp 50, the elastic member (peripheral spacer) 810 is arranged between the tubular portion 63 and the inner wall surface 711 of the cover 71 in a state of being elastically deformable.
Since the elastic member (peripheral spacer) 810 is arranged between the tubular portion 63 and the inner wall surface 711 of the cover 71, the elastic member (peripheral spacer) 810 is in a completed state in which the cover 71 is not filled with the silicone resin. The peripheral spacer) 810 can reliably maintain the posture of the light source unit 60 arranged in the cover 71.

The features of the manufacturing method of the lighting lamp 50 of this embodiment are as follows.
A mounting hole 611 or a mounting recess 103 for mounting the elastic member (peripheral spacer) 810 is formed on the substrate 61.
A light source unit 60 in which a light source 65 is mounted on an outer surface 84 of a tubular substrate 61 is manufactured.
An elastic member (peripheral spacer) 810 protruding toward the inner wall surface 711 of the cover 71 is attached to the light source unit 60.
The light source unit 60 to which the elastic member (peripheral spacer) 810 is attached is inserted into the translucent cover 71.
The cover 71 and the stem 76 are coupled, and the light source unit 60 is enclosed in the cover 71.

The silicone 53 may be injected between steps S14 and S15. That is, after the open portion of the cover 71 and the end portion of the stem 76 are melt-bonded, the silicone 53 extruded from the silicone dispenser is injected into the inside of the cover 71 as in the method of injecting the silicone 53 described in the first embodiment. You may.
Since the mounting hole 611 is completely closed by the spacer mounting portion 814, even if the inside of the cover 71 is filled with silicone resin, the mounting hole 611 does not leak to the inner side surface 89 side of the substrate 61.
In the lighting lamp 50 using the silicone resin, the silicone resin is arranged between the tubular portion 63 and the inner wall surface 711 of the cover 71, so that the cover 71 is filled with the silicone resin in a completed state. , The posture of the light source unit 60 arranged in the cover 71 can be reliably maintained by the silicone resin.
In the lighting lamp 50 using the silicone resin, the elastic member (peripheral spacer) 810 can reliably maintain the posture of the light source unit 60 arranged in the cover 71 while the lighting lamp 50 is being assembled. ..

*** Effect of Embodiment 5 ***
According to the present embodiment, the elastic member (peripheral spacer) 810, which is a separate part from the light source unit 60 and has elasticity, engages with the mounting hole 611 provided in the cylindrical portion 63 of the light source unit 60 and comes off. It is installed so that it does not exist.
Further, the elastic member (peripheral spacer) 810 is arranged between the tubular portion 63 and the inner wall surface 711 of the cover 71 in a state of being elastically deformable.
Therefore, the posture of the light source unit 60 arranged in the cover 71 can be reliably maintained in a state where the cover 71 is not filled with the silicone resin.
Here, "a state in which the cover 71 is not filled with silicone resin" is defined as "a state in which the cover 71 is not filled".

(B) The state of the lighting lamp 50 in the process of assembling without using silicone resin, and
(C) Includes three states, that is, the completed state of the lighting lamp 50 that does not use the silicone resin.
By setting the protruding height of the spacer main portion 811 higher than the height of the light source 65 of the tubular portion 63 and the height of the electronic component, it is possible to avoid direct contact between the lens tip portion of the LED and the inner wall surface 711 of the cover 71. .. Further, the light source unit 60 can be stably inserted into the cover 71 without tilting, and can be stored without tilting.
Further, it is possible to suppress the displacement of the light source unit 60 due to the impact or vibration applied to the lighting lamp 50 during the assembly of the lighting lamp 50 and in the completed state.

The spacer main portion 811Q in the present embodiment is formed in a substantially hemispherical shape.
As shown in FIG. 36, the maximum radial dimension of the spacer main portion 811Q is larger than the maximum dimension of the mounting hole 611Q, and when the light source unit 60 is housed in the cover 71, the spacer main portion 811Q is the substrate 61. It is arranged between the outer side surface 84 and the inner wall surface 711 of the cover 71.
The outer surface 84 of the substrate 61 is the surface of the substrate 61, and is the mounting surface of the light source 65 and other electronic components.
The spacer main portion 811Q comes into contact with the inner wall surface 711 of the cover 71.
The spacer main portion 811Q has a first contact portion (curved surface portion) 812 having a curved surface, a second contact portion (flat surface portion) 813 having a flat surface, and a second contact portion (flat surface portion) 813.

The elastic member (peripheral spacer) 810R in the present embodiment has a long connecting portion 819R, and an inclined surface portion 816 is formed at the tip of the connecting portion 819R. Further, the spacer mounting portion 814 (for example, the spacer mounting portion 814 described in the fifth embodiment (FIGS. 20 to 22)) protruding outward in the radial direction from the connecting portion 819R is not formed.
As shown in FIG. 39, when the light source unit 60 to which the elastic member (peripheral spacer) 810R is attached is housed in the cover 71, the first contact portion (curved surface portion) 812 is in contact with the inner wall surface 711. The second contact portion (flat surface portion) 813 is in contact with the outer surface 84 of the substrate 61.

*** Effect of Embodiment 11 ***
The elastic member (peripheral spacer) 810R in the present embodiment has a long connecting portion 819R. Therefore, the elastic member (peripheral spacer) 810R is not likely to come off from the mounting hole 611R even when elastically deformed.
The elastic member (peripheral spacer) 810R in the present embodiment does not have a spacer mounting portion 814 that projects radially outward from the connecting portion 819R. Therefore, the elastic member (peripheral spacer) 810R can be easily inserted into the mounting hole 611R. That is, the work of attaching the elastic member (peripheral spacer) 810R is improved, and the assembling property of the lighting lamp 50 is improved.
Further, the elastic member (peripheral spacer) 810R in the present embodiment does not have a spacer mounting portion 814 protruding outward in the radial direction from the connecting portion 819R.

FIG. 41 is a diagram showing an elastic member (peripheral spacer) 810S according to the twelfth embodiment.
As shown in FIGS. 40 and 41, the elastic member (peripheral spacer) 810S in the present embodiment is attached to the substrate 61 by using the screw 8133.

The elastic member (peripheral spacer) 810S in the present embodiment has a substantially circular bottom wall portion 8134 and a peripheral wall portion 8135 formed on the peripheral edge of one surface of the bottom wall portion 8134, and has a bottomed cylinder as a whole. It has a shape like a shape. The bottom wall portion 8134 may have a non-circular shape such as an ellipse, a polygon, or a star, and the elastic member (peripheral spacer) 810S may have a non-cylindrical shape such as a square cylinder.

The bottom wall portion 8134 is provided with a spacer screw hole 8132. The spacer screw hole 8132 is a through hole that penetrates the bottom wall portion 8134, and is a hole through which the screw 8133 is inserted.
The tip of the peripheral wall portion 8135 is the first contact portion 812 and abuts on the inner wall surface 711 of the cover 71. The other surface of the peripheral wall portion 8134 on which the peripheral wall portion 8135 is not formed is the second contact portion 813, which abuts on the outer surface 84 of the substrate 61.

The elastic member (peripheral spacer) 810S is attached to the substrate 61 with the recess 8131 surrounded by the bottom wall portion 8134 and the peripheral wall portion 8135 facing outward. Specifically, the elastic member (peripheral spacer) 810S is attached to the substrate 61 by screwing the screw 8133 inserted through the spacer screw hole 8132 into the attachment hole 611S provided in the substrate 61.

*** Effect of Embodiment 12 ***
Since the elastic member (peripheral spacer) 810S in the present embodiment is firmly attached to the substrate 61 by using the screw 8133, there is no possibility that the elastic member (peripheral spacer) 810S will come off from the substrate 61 even if it is elastically deformed.

In this embodiment, points different from the above-described embodiment will be described.
In particular, in this embodiment, the differences from the above-described embodiments 10 and 11 will be described.
FIG. 42 is a perspective view showing the elastic member (peripheral spacer) 810T in the thirteenth embodiment.
FIG. 43 is a three-view view showing the elastic member (peripheral spacer) 810T in the thirteenth embodiment.
FIG. 44 is a cross-sectional view illustrating the operation of the elastic member (peripheral spacer) 810T in the thirteenth embodiment.
As shown in FIGS. 42 and 43, the elastic member (peripheral spacer) 810T in the present embodiment has a different aspect of the spacer main portion 811T.

The elastic member (peripheral spacer) 810T in the present embodiment is composed of a connecting portion 819T which is a shaft portion to be inserted into the opening of the substrate 61 and a spacer main portion 811T formed at the tip of the shaft, and is a resin material having elasticity. Is formed by.
The connecting portion 819T has a cylindrical protruding portion 8191 and a neck portion 8192 arranged in the mounting hole 611, as in the eleventh embodiment described above.
The spacer main portion 811T of the elastic member (peripheral spacer) 810T in the present embodiment is formed in a substantially hemispherical shape.
As shown in FIG. 44, the maximum radial dimension of the spacer main portion 811T is larger than the maximum dimension of the mounting hole 611T, and when the light source unit 60 is housed in the cover 71, the spacer main portion 811T is the substrate 61. It is arranged between the outer side surface 84 and the inner wall surface 711 of the cover 71.
The outer surface 84 of the substrate 61 is the surface of the substrate 61, and is the mounting surface of the light source 65 and other electronic components.
The spacer main portion 811T contacts the inner wall surface 711 of the cover 71.
The spacer main portion 811T is connected at a first contact portion (curved surface portion) 812 having a curved surface, a second contact portion (flat surface portion) 813 having a flat surface, and a second contact portion (flat surface portion) 813. It is composed of a recess 8131 in which a portion on the side of the portion 819R is recessed, and a penetration portion 8136 that partially penetrates the first contact portion (curved surface portion) 812 and the second contact portion (flat surface portion) 813.
As shown in FIG. 44, when the light source unit 60 in which the elastic member (peripheral spacer) 810T is attached to the substrate 61 is housed in the cover 71, the first contact portion (curved surface portion) 812 is the inner wall surface 711. The second contact portion (flat surface portion) 813 is in contact with the outer surface 84 of the substrate 61.
The spacer main portion 811T is arranged in contact with the substrate 61 and the outer cover 71 in a state of being elastically deformed or in a state of being elastically deformable.
As shown in FIGS. 42 and 43, the penetrating portion 8136 has a slit shape cut linearly with substantially the same width dimension in the central axis direction from the peripheral edge portion of the spacer main portion 811T.
The penetrating portion 8136 penetrates the first contact portion (curved surface portion) 812 and the second contact portion (flat surface portion) 813 except for the portion of the spacer main portion 811T that is connected to the connecting portion 819R. Is formed in.

In the present embodiment, the penetration portions 8136 are formed in rotational symmetry (axisymmetric) at four locations of the spacer main portion 811T.
The penetrating portions 8136 are evenly arranged at a plurality of radial positions.
The number of penetrating portions 8136 is preferably 2 or more and 6 or less, and 4 is preferable.
In the present embodiment, the penetration portion 8136 is formed along a radial direction passing through the central axis X of the elastic member (peripheral spacer) 810T.
The penetrating portion 8136 can disperse the residual stress in a well-balanced manner in a state where the spacer main portion 811T is elastically deformed.
When stress is applied so as to crush the spacer main portion 811T along the direction of the central axis X of the elastic member (peripheral spacer) 810T, the spacer main portion 811T is elastically deformed so as to expand radially. At this time, since the elastic deformation is performed so that the width of the penetrating portion 8136 is widened, the spacer main portion 811T does not exceed the elastic limit and is not torn.

*** Effect of Embodiment 13 ***
The elastic member (peripheral spacer) is a cushioning bush for supporting the substrate 61 while suppressing an impact inside the cover 71 such as a glass tube, but the internal shape of the cover 71 or the cover 71 having a different tube diameter size may be used. There is a possibility that the substrate 61 cannot be supported due to a gap remaining because it cannot cope with the variation in dimensions. Further, if each component is manufactured with accurate dimensions that reliably support the substrate 61, there may be no gap between the components and it may be difficult to assemble.
A plurality of slits serving as a penetrating portion 8136 are formed on the side surface of the spacer main portion 811T of the elastic member (peripheral spacer) 810T. When stress is applied in the axial direction due to this slit, the spacer main portion 811T is deformed so as to spread laterally. Since the elastic member (peripheral spacer) 810T can be smoothly inserted even when the distance between the tip of the spacer main portion 811T and the cover 71 is narrowed, the distance dimension between the outer surface 84 of the substrate 61 and the inner wall surface 711 of the cover 71. Even if T3 has an arbitrary interval, it can be handled.
Since the elastic member (peripheral spacer) 810 of the above-described embodiment does not have a slit, the elastic member (peripheral spacer) 810 does not shrink and is difficult to insert when the distance dimension T3 between the substrate 61 and the cover 71 becomes narrow. Although there is a possibility, by making a slit in the spacer main portion 811T, it becomes easy to insert the substrate 61 into the cover 71 even if the distance dimension T3 is narrow. Further, even if the size of the cover 71 is different or the cover 71 is uneven, the substrate 61 can be supported.

The penetration portion 8136 of the elastic member (peripheral spacer) 810T in the present embodiment is formed in rotational symmetry (axial symmetry) with the spacer main portion 811T, and residual stress is obtained in a state where the spacer main portion 811T is elastically deformed. Is dispersed in a well-balanced manner, so that it is possible to prevent the spacer main portion 811T from tearing beyond the elastic limit.
As shown in FIG. 44, the spacer main portion 811T provided with the penetrating portion 8136 is stressed so as to be crushed along the direction of the central axis X of the elastic member (peripheral spacer) 810T. Elastically deforms in the direction of arrow E in (b) so as to spread radially without tearing. Therefore, as shown in FIG. 44 (b), even when the distance dimension T3 between the outer surface 84 of the substrate 61 and the inner wall surface 711 of the cover 71 is small, the spacer main portion 811T is the outer surface of the substrate 61. It can be arranged between the 84 and the inner wall surface 711 of the cover 71.
Further, when the light source unit 60 is inserted into the cover 71, the peripheral edge side of the spacer main portion 811T is elastically deformed so as to spread radially, so that the first contact portion (curved surface portion) 812 and the inner wall surface of the cover 71 are elastically deformed. Friction with the 711 is reduced, and the assemblability of the lighting lamp 50 is maintained.
The elastic member (peripheral spacer) 810T has a through portion 8136 formed in the spacer main portion 811T in a rotationally symmetric manner (axially symmetric), and the spacer main portion 811T is elastically deformed so as to expand radially without tearing. Therefore, the displacement of the light source unit 60 due to the impact or vibration applied to the lighting lamp 50 can be further suppressed during the assembly of the lighting lamp 50 and in the completed state.

*** Modification example ***
Not only four penetrating portions 8136 are present on the peripheral edge portion side of the spacer main portion 811T, but two or more penetrating portions 8136 may be present on the peripheral edge portion side of the spacer main portion 811T. That is, the number of penetrating portions 8136 may be an even number of 2 or more, or an odd number of 3 or more.
The penetrating portion 8136 may be formed along a spiral direction toward the central axis X of the elastic member (peripheral spacer) 810T.
The penetrating portion 8136 may be formed along a direction that does not pass through the central axis X of the elastic member (peripheral spacer) 810T.
The penetrating portion 8136 is not limited to a slit shape cut in a straight line with substantially the same width dimension, but may have a fan shape or a wavy shape.
The penetration portion 8136 may be a simple notch having a width dimension of substantially zero.
