<Effects of Embodiment 1>
As described above, the lamp 3 according to Embodiment 1 includes the light source section 30 in which the light emitting element 300 is arranged on the mounting surface section 302, which is one surface side of the substrate 301, and the support section 31 in which the light source section 30 is supported. The support portion 31 includes a placement surface portion 311 formed so that at least a portion of the mounting surface portion 302 of the substrate 301 abuts thereon, a non-placement surface portion 312 formed on the opposite side of the placement surface portion 311 and on which the light source portion 30 is not arranged, and a first region S1 which is a device side region facing at least a portion of the placement surface portion 311 and a second region S2 which is an irradiation side region facing at least a portion of the non-placement surface portion 312 so as to connect. , a communicating portion 313 is formed between the arrangement surface portion 311 and the non-arrangement surface portion 312 . As the light source unit 30 moves in the first region S1 along the direction intersecting the placement surface portion 311, the mounting surface portion 302 of the substrate 301 is supported by the support portion 31 so as to abut against the placement surface portion 311. Therefore, the light source portion 30 is stably placed on the placement surface portion 311 of the support portion 31 on the side of the first region S1 and does not deviate to the second region S2 side.

Since the lamp 3 according to Embodiment 1 is attached to the support portion 31 so that the area of the mounting surface portion 302, which is one surface of the substrate 301, where the light emitting element 300 is not mounted is in contact with the placement surface portion 311, the operating heat of the light emitting element 300 is transmitted from the mounting surface portion 302 to the support portion 31 through the shortest path, leading to improvements in the operational reliability and long-term reliability of the light source portion 30, the lamp 3, and the lighting device 1.

Further, in the lamp 3 according to Embodiment 1, with the light source unit 30 supported by the support portion 31, the portion of the mounting surface portion 302, which is one surface side of the substrate 301, that does not contact the placement surface portion 311 is exposed to the second region S2, which is the irradiation side region, through the communicating portion 313 formed in the support portion 31. The light emitting element 300 is mounted on the mounting surface portion 302 of the substrate 301 so that the light source portion 30 is supported by the supporting portion 31 so as to be arranged on a portion of the mounting surface portion 302 that is one surface side of the substrate 301 that does not come into contact with the mounting surface portion 311. Therefore, the light emitted from the light emitting element 300 is not blocked by the supporting portion 31, and the second region S2, which is the region on the irradiation side, can be irradiated without waste.

In the lighting device 3 according to Embodiment 1, when the communicating portion 313 is provided in the central portion of the support surface portion 310 in the lateral direction Y, the optical axis of the light emitting element 300 can be aligned with the center of the cover 33 in the lateral direction Y by supporting the light source portion 30 on the supporting portion 31 so that the optical axis of the light emitting element 300 passes through the communicating portion 313.

Furthermore, in the lighting fixture 3 according to Embodiment 1, the light emitting portion from which the light of the light emitting element 300 is emitted is arranged on the side of the second region S2, which is the region on the irradiation side, with respect to the non-arranged surface portion 312 in a state where the light source portion 30 is supported by the supporting portion 31, whereby the irradiation range (light distribution) in the lateral direction Y can be widened.

Further, in the lamp 3 according to Embodiment 1, at least one of the spring receiver 37, the control device 38, and the wire holder 40, which are lamp side connectors, is attached to the support portion 31 so as to straddle the slit-shaped communication portion 313 formed in the support surface portion 310, thereby reinforcing the support portion 31. That is, by attaching at least one of the spring receiver 37, the control device 38, and the wire holder 40, which are the connecting devices on the lamp side, to the support portion 31, it is possible to compensate for the decrease in rigidity of the support portion 31 due to the formation of the communication portion 313, and to suppress the deformation of the support portion 31.

The spring receiver 37 , the control device 38 , and the wire holder 40 , which are lamp-side connectors, are attached to the support portion 31 so as to straddle the slit-shaped communication portion 313 while being separated from the substrate 301 . That is, the spring receiver 37, the control device 38, and the wire holder 40 are attached to the supporting portion 31 so as to straddle the substrates 301 facing each other, and the substrates 301 are restricted from moving toward the fixture, so that they do not come off the lamp 3.

Furthermore, in the lighting fixture 3 according to Embodiment 1, the light source section 30, the spring receiving device 37, the control device 38, and the wire holder 40, excluding the cover 33, can be attached to the support section 31 from the placement surface section 311 side, so that the assembly work can be simplified and the assembly time can be shortened.

Embodiment 2.
With reference to FIGS. 9 and 10, the illumination device 1 according to the second embodiment will be mainly described with respect to parts different from those of the first embodiment. Parts having the same configurations as those of the lighting device 1 according to Embodiment 1 are denoted by the same reference numerals, and descriptions thereof are omitted.

9A and 9B are enlarged exploded perspective views showing the essential parts of the lamp 3 according to Embodiment 2. FIG. 9A is a perspective view from the second region S2 side, and FIG. 9B is a perspective view from the first region S1 side. FIG. 10 is a cross-sectional view of the lamp 3 according to Embodiment 2, and corresponds to the cross-sectional view taken along the line AA in FIG.

The lighting fixture 3 according to the second embodiment differs from the first embodiment in that a support portion 31a different from the support portion 31 is used.

The support portion 31a has a stepped portion 317 formed in the center region of the support surface portion 310a in the lateral direction Y and protruding toward the second region S2, which is the region on the irradiation side. The stepped portion 317 extends along the longitudinal direction X and includes a pair of stepped side portions 318 standing from the inner side of the end portion of the support surface portion 310a in the lateral direction Y along a direction intersecting the support surface portion 310a, and a stepped surface portion 319 connecting the tips of the pair of stepped side portions 318. A slit-shaped communicating portion 313 is formed along the longitudinal direction X in the central portion of the step surface portion 319 in the lateral direction Y. As shown in FIG.

In the second embodiment, substrate 301 is installed on stepped portion 319 . Specifically, the substrate 301 is placed on the stepped surface portion 319 so that the mounting surface portion 302 is brought into contact with the placement surface portion 311 a of the stepped surface portion 319 . At this time, the substrate 301 is placed on the stepped surface portion 319 so that the light emitting element 300 mounted on the mounting surface portion 302 is arranged in the region of the stepped surface portion 319 where the communicating portion 313 is formed.

The length dimension of the placement surface portion 311a in the lateral direction Y (the width dimension of the placement surface portion 311a) corresponds to the length dimension of the substrate 301 in the lateral direction Y (the width dimension of the substrate 301). The length dimension of the stepped side portion 318 along the vertical direction Z (the height dimension of the stepped side portion 318) is determined in consideration of the graininess of the light emitting element 300 through the cover main portion 331, the light distribution balance to the side of the lamp 3, and the like.

<Action and effect of the second embodiment>
In the lamp 3 according to Embodiment 2, by increasing the length dimension of the stepped side portion 318 (the height dimension of the stepped side portion 318), the light distribution performance of the lamp 3 to the side is improved.

Further, in the lighting device 3 according to Embodiment 2, if the length dimension of the stepped side portion 318 (the height dimension of the stepped side portion 318) is made larger than the thickness dimension of the substrate 301, the spring receiver 37 attached to the placement surface portion 311, the control device 38 (control unit housing 381), and the wire holder 40 and the substrate 301 do not come into contact with each other.

In the lamp 3 according to Embodiment 2, a stepped portion 317 is formed in the central region of the support surface portion 310a in the lateral direction Y, thereby reinforcing the support portion 31a. That is, the stepped portion 317 compensates for the decrease in rigidity of the support portion 31a due to the formation of the communication portion 313, and suppresses deformation of the support portion 31a.

Furthermore, in the lighting device 3 according to Embodiment 2, when the light source section 30 (substrate 301) is attached to the support section 31 from the placement surface section 311 side, alignment can be performed by the stepped section 317. Therefore, it is possible to perform accurate assembly work while shortening the assembly time.

The lamp 3 according to Embodiment 3 includes a substrate holder 36 that holds the substrate 301b. The substrate holder 36 is provided with a substrate holding portion 360 that extends along the longitudinal direction X and is composed of a holding surface portion 361 that is a rectangular flat plate, a pair of holding side portions 365 standing from the end of the holding surface portion 361 in the transverse direction Y along a direction that intersects the holding surface portion 360, and a collar portion 366 that protrudes outward in the transverse direction Y from the tips of the pair of holding side portions 365. A plurality of holder communicating portions 364 arranged along the longitudinal direction X are formed in the central portion of the holding surface portion 360 in the lateral direction Y. As shown in FIG.

The substrate holder 36 is formed using an electrically insulating resin material, ceramic material, or the like. The substrate holding part 360 has a substantially U-shaped cross-sectional shape that intersects the longitudinal direction X, and extends along the longitudinal direction X. As shown in FIG.

When the lamp 3 is attached to the lamp mounting portion 21 of the fixture 2, the holder arrangement surface portion 362 of the holding surface portion 361 faces the first region S1, which is the fixture side region, and faces the fixture bottom surface portion 210 of the fixture 2. A holder non-arrangement surface portion 363 on the opposite side of the holder arrangement surface portion 362 faces the second region S1, which is the irradiation side region, and faces the cover main portion 331 of the cover 33 .

The length dimension of the holder arrangement surface portion 362 in the lateral direction Y (the width dimension of the holder arrangement surface portion 362) corresponds to the length dimension of the substrate 301b in the lateral direction Y (the width dimension of the substrate 301b). The length dimension of the holding side portion 365 (the height dimension of the holding side portion 365) along the vertical direction Z is determined in consideration of the graininess of the light emitting element 300 through the cover main portion 331, the light distribution performance to the side of the lamp 3, and the like.

<Action and effect of the third embodiment>
In the lamp 3 according to Embodiment 3, the lateral light distribution performance of the lamp 3 is improved by increasing the length dimension of the holding side portion 365 (the height dimension of the holding side portion 365).

Since the lamp 3 according to the third embodiment is installed on the supporting portion 31 with the substrate 301b held by the substrate holder 36 formed using a resin material having electrical insulation, the electrical insulation (dielectric strength performance) of the substrate 301b is improved.

The lighting fixture 3 according to Embodiment 3 is installed on the support portion 31 with the substrate 301b held by the substrate holder 36 formed using a resin material having electrical insulation, so that the substrate 301b can be miniaturized and the material cost can be reduced.

In the lighting device 3 according to Embodiment 3, the substrate 301b is held by the substrate holder 36 formed using an electrically insulating resin material. Therefore, the holder communicating portion 364 can be made small or can be formed separately corresponding to the plurality of light emitting elements 300. This compensates for the decrease in rigidity of the substrate holder 36 or the support portion 31, and suppresses deformation of the support portion 31.
