  In recent years, in the field of integrated LED base lights, a lighting device has been proposed in which a plurality of light emitting units are arranged in series in the same direction to make it appear as if it were a single long light emitting unit. However, in such a lighting device, it is necessary to fix the light emitting element substrate to the support member provided in the light emitting unit. When the light emitting element substrate is not fixed to the support member, the light emitting element substrate floats from the support member.

It has a shape that spreads out. In practice, at least one of the first side edge 111 b and the second side edge 111 c has a shape that spreads in the light irradiation direction of the light emitting unit 20 (that is, in the −Z direction in FIG. 3). Just do it.
Thus, the bottom plate portion 111 a, the first side edge portion 111 b, and the second side edge portion 111 c form a recess that is open in the light irradiation direction of the light emitting unit 20.

  The first side plate 121a and the second side plate 121b are closing members attached to the opening portions at both ends in the longitudinal direction of the attaching member 111 in the direct attachment trough type illumination device, and are formed of, for example, a resin material.

The light emitting element 21 is, for example, an LED chip. A plurality of light emitting elements 21 are mounted on the light emitting element substrate 22. The power supply unit 23 is electrically connected to the light emitting element substrate 22 on which the light emitting element 21 is mounted. The support member 24 supports the power supply unit 23 on the back side and the light emitting element substrate 22 and the reflection member 26 on the front side. The substrate fixing member 25 fixes the light emitting element substrate 22 on the surface side of the support member 24. The front surface side of the support member 24 is entirely covered by a translucent cover 27. The translucent cover 27 is attached to the instrument body 10 together with the support member 24 in a state of covering the front surface side of the support member 24. Further, although illustration is omitted, a hole is opened between the light emitting element substrate 22 and the substrate fixing member 25 so that the light emitting element 21 is exposed on the light emitting element substrate 22 and the outer dimension is light emission A reflector substantially identical to the element substrate 22 is provided. There is almost no gap between the reflection plate and the substrate fixing member 25.
Here, the light emitting element substrate 22, the support member 24, the reflecting member 26, the light transmitting cover 27, and the reflecting plate (not shown) are all elongated with their longitudinal directions aligned with the instrument body 10.

(Power supply part)
As shown in FIG. 3, the power supply unit 23 is disposed at the center in the width direction of the lighting device 1 in the internal space of the lighting device 1 (inside the recess of the tool main body 10). The power supply unit 23 is fixed to the back surface side of the support member 24 by, for example, a fastening member such as a screw.
The power supply unit 23 is electrically connected to the light emitting element substrate 22 through the wiring 23 d (see FIG. 12 described later). The wiring 23 d is connected from the power supply unit 23 fixed on the back surface side of the support member 24 to the light emitting element substrate 22 fixed on the front surface side of the support member 24 through a through hole provided in the support member 24. . The power supply unit 23 is connected, for example, to a power supply cable (not shown) led out to the internal space of the lighting apparatus 1 from the mounting surface of the construction material B to which the tool body 10 is attached, and supplied from the power supply cable AC power is converted to DC, and the output (that is, DC power) is supplied to the light emitting element 21 through the wiring 23 d. The power supply cable is wired in a power supply cable housing space secured between the upper surface of the power supply unit 23 and the tool body 10.

(Supporting member)
As shown in FIG. 3, the support member 24 supports the light emitting element substrate 22 on which the light emitting element 21 is mounted. The support member 24 also has a function of a heat sink for radiating the heat of the light emitting element 21.
The support member 24 has an elongated main surface portion 24 a, a first side surface portion 24 b, a bottom surface portion 24 c, and a second side surface portion 24 d.

The light emitting element substrate 22 is attached to the front surface side facing downward, and the power supply unit 23 is attached to the back surface side facing upward. The main surface portion 24 a is formed wider than the width of the light emitting element substrate 22.
The first side surface portion 24b is bent in the light irradiation direction (that is, the -Z direction in FIG. 3) from the end in the width direction of the main surface portion 24a, and extends along the light irradiation direction.

The bottom surface portion 24c is a direction which intersects the light irradiation direction from the end portion of the first side surface portion 24b opposite to the end portion in contact with the main surface portion 24a (that is, in the Y direction or -Y direction in FIG. 3). It is bent and extends outward in the width direction of the main surface 24a.
The second side surface portion 24d is bent in the direction crossing the bottom surface portion 24c (that is, the Z direction in FIG. 3) from the end portion of the bottom surface portion 24c opposite to the end portion in contact with the first side surface portion 24b. , It extends to the opposite side of the light irradiation direction. The second side surface portion 24d abuts against an inner wall surface in the width direction of the translucent cover 27 described later.

The first side surface portion 24b, the bottom surface portion 24c and the second side surface portion 24d form convex portions protruding in the light irradiation direction on both ends of the main surface portion 24a. It is preferable that the top of the convex portion be formed to be inclined so as to project more greatly toward the outside in the width direction of the support member 24. Further, it is preferable that the top of the convex portion be shaped so as not to enter the half beam angle region of the light emitting element 21. The main surface portion 24a supporting the light emitting element substrate 22 is formed to be recessed relative to the convex portion in the direction of the tool body 10 (that is, the Z direction in FIG. 3).
Further, the support member 24 fixes the light emitting element substrate 22 by the substrate fixing member 25 mounted on the main surface portion 24 a.

(Board fixing member)
FIG. 4 is an exploded perspective view for explaining the mounting relationship between the support member 24, the power supply unit 23 and the substrate fixing member 25.
FIG. 5 is a perspective view for explaining the mounted state of the power supply unit 23 and the substrate fixing member 25 in the support member 24. As shown in FIG.
As shown in FIGS. 4 and 5, the power supply unit 23 and seven substrate fixing members 25 (substrate fixing members 251 a to 251 f, and a central substrate fixing member 252) are mounted on the support member 24. However, in practice, the number of substrate fixing members 25 is not limited to seven. The number of substrate fixing members 25 is arbitrary, and is generally determined according to the design and dimensions of the lighting device 1.

The substrate fixing members 25 (substrate fixing members 251 a to 251 f and the central substrate fixing member 252) are provided on the main surface portion 24 a of the support member 24 and fix the light emitting element substrate 22 to the support member 24.
As shown in FIG. 3, the substrate fixing member 25 supports both sides in the width direction of the light emitting element substrate 22, and has a shape projecting on the light emitting element mounting surface of the light emitting element substrate 22. Therefore, the light emitting element substrate 22 is fixed by the substrate fixing member 25 so as not to float on the support member 24.

  Furthermore, as shown in FIGS. 4 and 5, on the back surface side of the main surface portion 24a of the support member 24, the power supply unit 23 is attached from above the substrate fixing member 251c. That is, the substrate fixing member 251 c is covered by the power supply unit 23. However, in practice, it is not limited to this example.

FIG. 6 is a view for explaining the shapes of the substrate fixing members 251a to 251f.
FIG. 7 is a view for explaining the shape of the center substrate fixing member 252. As shown in FIG.
As shown in FIGS. 6 and 7, the substrate fixing member 25 (substrate fixing members 251a to 251f and the central substrate fixing member 252) comprises a first claw 25a and a second claw 25b, and a flat portion 25c. Prepare.

  The first claw 25a and the second claw 25b are a pair of claws formed on the flat surface 25c, and are inserted through the insertion holes of the main surface 24a of the support member 24 and the back surface of the main surface 24a of the support 24 Project from the side to the surface side. The first claw portion 25 a and the second claw portion 25 b support both sides of the light emitting element substrate 22 so as to sandwich the light emitting element substrate 22 from both sides in the width direction, and on the light emitting element mounting surface of the light emitting element substrate 22. It has a shape that protrudes to For example, the first claw 25a and the second claw 25b have a shape in which the tip is bent at a right angle like a hook.

As shown in FIG. 6 and FIG. 7, the tips of the first claw 25 a and the second claw 25 b are central portions in which both end portions in the longitudinal direction of the support member 24 are most separated from the flat portion 25 c Is the shape (for example, an arc shape) closest to the flat portion 25c.
Specifically, the first claw portion 25a and the second claw portion 25b have a length of a portion protruding from the flat portion 25c (a portion through which the insertion hole of the main surface portion 24a of the support member 24 is inserted) Both end portions in the longitudinal direction of the first claw 25a and the second claw 25b are longer than the central portion in the longitudinal direction of the second claw 25b.
When the light emitting element substrate 22 is mounted, the light emitting element substrate 22 is fixed at the central portion described above. The both end portions described above sandwich the central portion and are farther from the light emitting element substrate 22 than the central portion. The portion protruding from the flat portion 25c approaches the light emitting element substrate 22 as it gets closer to the central portion from both end portions.

  The flat portion 25c is disposed on the back surface side of the main surface portion 24a of the support member 24, and the first claw portion 25a and the second claw portion 25b are provided on the surface facing the back surface side of the main surface portion 24a of the support member 24. . At this time, the first claw 25a and the second claw 25b pass through the insertion hole of the main surface 24a of the support member 24 from the flat surface 25c of the substrate fixing member 25 on the back surface side of the main surface 24a of the support member 24. Thus, the substrate fixing member 25 is temporarily fixed. Further, the light emitting element substrate 22 is attached between the pair of claws on the front surface side of the main surface 24 a of the support member 24, thereby completing the fixation of the substrate fixing member 25.

  The flat surface portion 25c may be fixed to the back surface side of the main surface portion 24a of the support member 24 by, for example, a fastening member such as a screw. At this time, since the light emitting element substrate 22 is disposed in the region between the first claw 25a and the second claw 25b on the surface side of the main surface 24a of the support member 24, fastening of a screw or the like is performed in the flat portion 25c. The member and the insertion hole thereof are disposed in a portion other than the region between the first claw 25a and the second claw 25b. For example, a fastening member such as a screw and its insertion hole are provided at the peripheral edge of the flat portion 25c. Thereby, the substrate fixing member 25 can be fixed by a fastening member such as a screw without affecting the light emitting element substrate 22.

As shown in FIG. 7, the center substrate fixing member 252 further includes a wiring protection portion 25d in addition to the first claw portion 25a, the second claw portion 25b, and the flat portion 25c.
The wire protection portion 25d is disposed on the back surface side of the main surface portion 24a of the support member 24 like the flat surface portion 25c, and is connected to the light emitting element substrate 22 from the power supply portion 23 on the back surface side of the main surface portion 24a of the support member 24. And protect the through hole. The wire protection portion 25 d is shaped (for example, a half cylinder) capable of storing the wire 23 d disposed on the back surface side of the main surface portion 24 a of the support member 24. The wire protection portion 25d may be formed by deforming a part of the flat portion 25c.
The wiring 23 d led out from the power supply unit 23 is covered with the wiring protection unit 25 d so that the light emitting element substrate 22 on the front surface side of the main surface 24 a is not exposed on the back surface side of the main surface 24 a of the support member 24. Can be connected with For this reason, it is not necessary to lead the wiring 23 d in a wide area on the support member 24, the wiring 23 d can be shortened, and the assemblability of the light emitting unit 20 is improved. In addition, since the wiring 23 d is not exposed on the back surface side of the main surface portion 24 a of the support member 24, the safety is improved and the double coating of the wiring becomes unnecessary.

It is fixed with an adhesive or the like (for example, double-sided tape) at an arbitrary position on the top of the convex portion. That is, when the reflection member 26 (the first reflection member 261, the second reflection member 262) is attached to the support member 24, the surface side (the first side surface portion 24b, the bottom surface portion 24c) of the bottom surface portion 24c of the support member 24. And the top of the convex portion formed by the second side surface portion 24d).

A hole is opened on the light emitting element substrate 22 so as to expose the light emitting element 21, and a reflecting plate (not shown) whose outer dimension is substantially the same as that of the light emitting element substrate 22 is provided. However, in practice, the number of light emitting element substrates 22 is not limited to two. For example, one sheet or three or more sheets may be used. That is, the number of light emitting element substrates 22 is arbitrary, and is usually determined in accordance with the design and dimensions of the lighting device 1.

  As shown in FIGS. 10 and 11, the light emitting element substrate 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) is a long plate-like member elongated in one direction. The plurality of elongated light emitting element substrates 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) are in the longitudinal direction of the light emitting element substrate with the short sides (ends in the longitudinal direction) facing each other. Arranged in a row.

  As shown in FIG. 10, the light emitting element substrate 22 (the first light emitting element substrate 221, the second light emitting element substrate 222) is a substrate fixing member at the main surface 24a of the support member 24 from the end in the longitudinal direction of the support member 24. It inserts between the 1st nail | claw part 25a and the 2nd nail | claw part 25b of 25 (substrate fixing member 251a-251f, the board | substrate fixing member 252 for center).

It is placed in the covering position.

Such a wiring suppression unit 28 (a power connection wiring suppression unit 28 a, a substrate connection wiring suppression unit 28 b) is formed, for example, by injection molding of a resin material.
The wiring suppression portion 28 (the power connection wiring suppression portion 28a and the substrate connection wiring suppression portion 28b) may be formed of, for example, a highly reflective material. The wiring suppressing portion 28 (the power connection wiring suppressing portion 28 a and the substrate connection wiring suppressing portion 28 b) is made of the highly reflective material, and the reflection member 26 (the first reflection member 261, the second reflection member 262) Similarly, the light of the light emitting element 21 can be efficiently reflected.
Alternatively, the wiring suppression unit 28 (the power connection wiring suppression unit 28a and the substrate connection wiring suppression unit 28b) may be formed of, for example, a transparent material. By forming the transparent material, the wiring state of the wiring 22c and the wiring 23d can be confirmed through the wiring suppression unit 28 (the power connection wiring suppression unit 28a and the substrate connection wiring suppression unit 28b).

(Translucent cover)
The translucent cover 27 covers the surface side (surface side on which the light emitting element substrate 22 and the reflecting member 26 are mounted) of the main surface portion 24 a of the support member 24, and the light emitting unit 20 is attached to the instrument body 10. It has a shape in which a part is inserted inside the recess of the main body 10. At this time, at least a part of the outer wall surfaces at both ends in the width direction of the translucent cover 27 abuts at least a part of the inner wall surfaces of the first side edge 111 b and the second side edge 111 c of the instrument body 10. The translucent cover 27 is white, for example, and has a function (a light diffusing property) to diffuse the light emitted from the light emitting element 21.

  As shown in FIG. 2, the translucent cover 27 includes a main cover 271, a first end cover 272 a and a second end cover 272 b. The main cover 271 covers the light emitting element substrate 22 on which the light emitting element 21 is mounted. The first end cover 272 a is attached to cover one end of the main cover 271. Similarly, the second end cover 272b is attached to cover the other end of the main cover 271.

Further, as shown in FIG. 3, on the inner wall surfaces on both sides in the width direction of the main cover 271, a first protrusion 271 a and a second protrusion 271 b are formed. The first projecting portion 271a and the second projecting portion 271b are separated in the vertical direction (that is, ± Z direction in FIG. 3) and extend in the longitudinal direction of the main cover 271 in parallel with each other. The shapes of the first protrusion 271a and the second protrusion 271b may not be the same.

  The first protrusion 271 a and the second protrusion 271 b fix the second side surface 24 d of the support member 24. At this time, the first projecting portion 271 a and the second projecting portion 271 b abut on the second side surface portion 24 d of the support member 24 on both sides in the width direction of the main cover 271. For example, the second side surface portion 24d of the support member 24 is fitted between the first protrusion 271a and the second protrusion 271b. Alternatively, the first protrusion 271 a and the second protrusion 271 b may sandwich the second side surface 24 d of the support member 24. With this configuration, the support member 24 can be fixed to the translucent cover 27 by the first projection 271 a and the second projection 271 b, and the support member 24 falls off from the translucent cover 27. Can be prevented more reliably.

  Furthermore, the second protrusion 271 b and the bottom surface 24 c of the support member 24 may sandwich the peripheral edge of the reflective member 26 in the width direction. With this configuration, the peripheral edge of the reflection member 26 in the width direction can be fixed to the bottom surface 24 c of the support member 24 by the second projection 271 b and the bottom surface 24 c of the support member 24. It is possible to prevent the reflecting member 26 from falling off from the bottom surface portion 24c of the second embodiment. When the peripheral edge of the reflection member 26 in the width direction is separately fixed to the bottom surface 24c of the support member 24 with an adhesive or the like (for example, a double-sided tape), the second projection 271b and the bottom surface of the support member 24 The portion 24 c may not hold the peripheral edge in the width direction of the reflecting member 26.

The light emitting unit 20 is attached in such a manner that a part of both side surfaces of the light transmitting cover 27 enters the opening of the instrument body 10. At this time, the light emitting unit 20 is a device in a state where a part of both side surfaces of the translucent cover 27 is in contact with the inner wall surface (the first side edge 111 b and the second side edge 111 c) of the recess of the device body 10 It is attached to the main body 10.
As a result, even when the light emitting unit 20 is bent, the appearance defect of the lighting device hardly occurs. This is because only a part of the translucent cover 27 that has entered the recess when the light emitting unit 20 is bent is exposed, and a gap does not occur between the device body 10 and the light emitting unit 20.

The light emitting element substrate, the reflecting member, the support member, the light transmitting cover, and the device body are all elongated in the longitudinal direction. The substrate fixing member has a pair of claws hooked to the end of the light emitting element substrate from the outside of the light emitting element substrate in the lateral direction, and a plurality of claws are provided along the longitudinal direction of the light emitting element substrate There is.
As a result, since the light emitting element substrate is fixed by the pair of claws on the surface side of the support member to which the light emitting element substrate is attached, it is possible to minimize the influence on light distribution characteristics and visibility. It becomes possible to prevent the substrate from floating from the support member.

(2) The pair of claws are disposed on both sides in the short direction of the light emitting element substrate, are opposed to each other, extend along the main emission direction of the light emitted by the light emitting element, and the extended portion is the light emitting element It is bent toward the inside in the short direction of the substrate.

The support member and the reflection member each have an insertion hole through which the pair of claws is inserted. The pair of claws pass through the respective insertion holes from the flat surface portion and project to the surface side of the support member. Then, at least a part of the pair of claws abuts and fixes the light emitting element substrate.
As a result, the substrate fixing member can be fixed to the support member without using a fastening member such as a screw.

(4) As for the pair of claws, the length of the portion protruding from the flat portion is longer at both end portions in the longitudinal direction of the pair of claws than at the central portion in the longitudinal direction of the pair of claws.
As a result, with respect to the height of a portion (a portion through which the insertion hole of the support member is inserted) protruding from the flat portion, both end portions are higher than the central portion, and the light emitting element substrate is interposed between the pair of claw portions from both end portions. When sliding in, it is possible to realize a structure in which the light emitting element substrate can be easily inserted from both end portions.

(5) The central portion of the above fixes the light emitting element substrate. The both end portions described above sandwich the central portion and are farther from the light emitting element substrate than the central portion. The portion protruding from the above flat portion approaches the light emitting element substrate as it gets closer to the central portion from both end portions.
As a result, both end portions are widely opened, and a guide surface is formed when pushing the light emitting element substrate from the both end portions to the center portion, and the light emitting element substrate can be easily inserted between the pair of claws from both end portions. It is possible to realize the structure.

(6) The power supply wiring is drawn out from the power supply section that supplies power to the light emitting element and is connected to the light emitting element substrate. The substrate fixing member adjacent to the power supply wire has a wire protection portion covering the power supply wire, in addition to the flat portion and the pair of claws.
As a result, it is possible to protect the power supply wiring by using a part of the substrate fixing member and to prevent the exposure of the power supply wiring.
