Further, as shown in FIG. 2, when the light source unit 100 is attached to the lighting fixture 200, at least a part of the power supply device 140 included in the light source unit 100 is inserted into the recess 211 through the opening 211c.

Although not shown, the terminal block 240 is connected to a power supply wire 500a connected to an external power supply. Further, although not shown, the terminal block 240 is connected with a feed wire 500b that sends power or a signal to an adjacent lighting fixture when the lighting fixture 200 is connected in the longitudinal direction. Therefore, the power supply wire 500a, the feed wire 500b, and the like are arranged in the recess 211.
Although not shown in FIG. 3, the bottom surface portion 211a has a power wire insertion hole 250 through which the power wire 500a passes, and a bolt insertion hole into which a hanging bolt 400 hung from a mounting portion 300 such as a ceiling is inserted. Various holes 2501 such as 251 are formed.

<State in which the light source unit 100 is attached to the lighting fixture 200>
As shown in FIG. 2, the light source unit 100 is mounted in the recess 211 with the device mounting surface 111d, which is the back surface of the substrate mounting surface 111a, facing the bottom surface 211a of the recess 211. Further, the light source unit 100 is attached to the recess 211 with the cover side portion 131 facing the opening edge portion 211ba.
At this time, a gap portion 190 is formed between the cover side portion 131 and the opening edge portion 211ba.

The cover 130 includes a cover body 132 facing the light emitting element 120a. The cover main body 132 is formed continuously from the lower end portions of the cover side portions 131 on both sides in the lateral direction.

The cover extending portion 1312 is formed between the cover engaging portion 1311 and the cover side surface portion 1313, and projects in a direction away from the central portion of the recess 211.
The gap portion 190 is formed between the cover extension portion 1312 and the opening edge portion 211ba.

The cover engagement portion 1311 is formed inside the upper portion of the cover side surface portion 1313 along the rising portion 112.
The cover side surface portion 1313 has an upper end portion joined to the outer side portion of the cover engagement portion 1311, and a lower end portion joined to the lateral direction end portion of the cover body 132.
The cover extending portion 1312 projects toward the opening edge portion 211ba from the portion where the cover side surface portion 1313 is joined to the outer side portion of the cover engaging portion 1311 when the light source unit 100 is attached to the lighting fixture 200.

  The gap 190 is preferably about several millimeters, and is preferably about 1 mm to 5 mm. Especially preferred is 2 mm to 4 mm. The gap 190 may have a value other than the above values.

Holes 2501 such as a power supply line insertion hole 250 and a bolt insertion hole 251 are formed in the bottom surface portion 211a of the recess 211.
The air that has flowed into the recess 211 from the gap 190 flows out from the hole 2501 formed in the bottom surface 211a. An air flow path is formed inside the recess 211.
Note that the bottom surface portion 211a of the recess 211 is formed with holes 2501 such as the power supply line insertion hole 250 and the bolt insertion hole 251, but other than the power supply line insertion hole 250 and the bolt insertion hole 251, an air flow path is provided. You may form a hole for the purpose of forming.

The opening edge portion 211ba has a curved portion 211bb that is smoothly curved in a direction away from the central portion of the concave portion 211. The curved portion 211bb is formed by bending the side surface portion 211b of the recess 211 outward.
Further, the cover extending portion 1312 forms a curved surface protruding toward the curved portion 211bb.
As described above, since the gap 190 has curved surfaces on both sides in the lateral direction, it has a shape in which air easily flows.

<Installation process of the light source unit 100 to the lighting fixture 200>
Next, a mounting process for mounting the light source unit 100 on the lighting fixture 200 will be described. The lighting fixture 200 can be attached to the attachment part 300 such as the ceiling by fixing it to the hanging bolt 400 suspended from the ceiling or by fixing it directly to the ceiling with a fixture such as a screw.

When the lighting fixture 200 is attached to the mounting portion 300, the power supply wire 500a drawn from the ceiling, that is, the F cable is drawn into the recess 211 of the lighting fixture 200 through the power supply wire insertion hole 250 and connected to the terminal block 240.
Next, the spring 230 is engaged with the fixture 150 of the light source unit 100, and the connector 502 of the harness 500d of the terminal block 240 and the power supply device in a state where a working space exists between the light source unit 100 and the lighting fixture 200. Operations such as connecting the first electric wire 500c of the connector 140 to the connector 501 are performed. Then, the light source unit 100 is pushed up toward the lighting fixture 200, and the light source unit 100 is attached to the lighting fixture 200.

<Explanation of Notch 195>
In the LED module 120, the light emitting element 120a and the wiring pattern 120c are arranged on the mounting surface (front surface) of the substrate 120b, and the non-mounting surface (back surface) is in contact with the board mounting surface portion 111a. It is attached to the surface portion 111a. That is, the frame part 110 attaches the substrate 120b in a state of being in contact with the substrate 120b. The operating heat of the light emitting element 120a is transferred to the frame part 110 from the non-mounting surface (back surface).

As shown in FIGS. 7 and 8, the frame portion 110 is formed with a notch 195 in which a frame edge portion 1105 which is an outer peripheral edge portion is cut out, and at least the substrate peripheral edge portion 1205 which is a peripheral edge portion of the substrate 120b. The substrate 120b is attached so that a part thereof overlaps the notch 195.
The frame portion 110 is formed with a cutout 195 in which the frame edge portion 1105 at the end in the longitudinal direction of the frame edge portion 1105 which is the outer peripheral edge portion is cut out. Further, the substrate 120b is attached in a state where the substrate peripheral portion 1205 at the longitudinal end of the substrate peripheral portion 1205 overlaps the edge portion of the notch 195.

  The frame portion 110 is formed with a notch 195 in which both ends in the longitudinal direction of the plane portion 111 are notched. In FIG. 4 to FIG. 6, the notch 195 is shown only at the right end portion of the frame portion 110 toward the drawings, but the notch 195 is also formed at the left end portion. However, in FIGS. 4 to 6, the notch 195 at the left end is covered with the second wire clamp 170 that is a harness clamp, and is not visible. The notch 195 is formed near the center of the flat portion 111 in the lateral direction. The notch 195 in the present embodiment is formed in a substantially U-shape with both ends in the longitudinal direction open.

The cutouts 195 are formed by cutting out from the both ends in the longitudinal direction of the substrate 120b attached to the substrate attachment surface portion 111a to the center side in the longitudinal direction. That is, the end portion in the longitudinal direction of the substrate peripheral portion 1205 overlaps the notch 195. The notch 195 is formed by an electronic component such as the light emitting element 120a mounted on both ends of the substrate 120b in the longitudinal direction, or a wiring pattern 120c laid at the end in the longitudinal direction of the substrate 120b for electrically connecting the electronic component. Is also cut out to the center side in the longitudinal direction.
That is, as shown in FIGS. 9 and 10, the cutout 195 is formed by cutting out to the center side in the longitudinal direction from the conductive portion from the most end in the longitudinal direction of the substrate 120b attached to the substrate attachment surface portion 111a. ing. For this reason, the board 120b is attached to the frame section 110 in a state where a part of the regions on both end sides in the longitudinal direction of the non-mounting surface do not contact the board attachment surface section 111a.

FIG. 11 is a diagram for explaining the effect of the light source unit 100 according to the present embodiment, (a) is a configuration of the present embodiment, and (b) is a diagram showing a configuration for comparison used for comparison. is there.
In the frame portion 110, the substrate 120b is attached in such a manner that a portion of the substrate peripheral portion 1205 whose distance from the conductive portion including the light emitting element 120a is smaller than the reference dimension Lth overlaps the notch 195. More specifically, in the frame portion 110, a portion where the value obtained by adding the distance T to the conductive portion including the light emitting element 120a and the thickness T of the substrate in the peripheral portion 1205 of the frame becomes smaller than the reference dimension Lth is the notch 195. The substrate 120b is attached in an overlapping state. The reference dimension Lth is also referred to as a reference creepage distance. Note that the reference dimension Lth is larger than the thickness dimension T of the substrate 120b.

As shown in FIG. 11A, the creepage distance Ln between light emitting element 120a and frame portion 110 in the present embodiment is Ln = Ls + T + Lb. Ls is the distance between the substrate peripheral portion 1205 and the conductive portion such as the light emitting element 120a. That is, it is the distance (mounting surface side creepage distance) between the end portion in the longitudinal direction of the substrate 120b and the conductive portion such as the light emitting element 120a mounted on the outermost end side of the mounting surface closest to the end portion. T is the thickness dimension of the substrate 120b. Lb is the shortest distance (the creepage distance on the non-mounting surface side) between the end portion of the substrate 120b in the longitudinal direction and the frame portion 110 contacting the non-mounting surface. The non-mounting surface side creepage distance Lb is a creepage distance obtained by forming the notch 195.
Therefore, according to the light source unit 100 of FIG. 11A, the creepage distance Ln not less than the reference dimension Lth is obtained by adjusting the creepage distance Lb on the non-mounting surface side, that is, Lth ≦ Ln = Ls + T + Lb. Therefore, the light emitting element 120a can be arranged close to the edge of the substrate 120b in the longitudinal direction, and the brightness on the edge side in the longitudinal direction can be improved. Further, in the light source unit 100 of the present embodiment, when a plurality of light source units 100 are connected in the longitudinal direction, the brightness in the entire longitudinal direction including the connecting portion can be made uniform.

  On the other hand, as shown in FIG. 11B, the creepage distance Lo between the light emitting element 120a and the frame portion 110 in the comparative configuration is the mounting surface side creepage distance Ls and the thickness dimension of the substrate 120b. And is the distance added. That is, Lo = Ls + T. Therefore, it is necessary to dispose the substrate 120b so that the creepage distance Lo is equal to or larger than the reference dimension Lth, and the disposition of the substrate 120b is limited.

*** Explanation of the effect of this embodiment ***
As described above, the light source unit of the present embodiment includes the substrate on one surface of which the conductive portion including the electrode portion on which the light source is mounted and the wiring pattern connected to the electrode portion is formed. In addition, the frame portion is provided with a substrate mounting surface portion to be mounted in a state where the other surface of the substrate facing the one surface is in contact with the other surface. Further, in the light source unit, when the distance from the conductive portion of the substrate to the outer peripheral end portion on one surface is the first dimension that is smaller than the predetermined reference dimension Lth, the substrate arranging portion of the frame portion is on the other surface of the substrate. A non-contact portion where the other surface of the substrate does not contact is provided in a region defined by the second dimension that is the difference between the reference dimension Lth and the first dimension with respect to the outer peripheral edge. Further, on the board, electrode portions are formed on one surface of the board so that the light sources are mounted in rows, and the reference dimension Lth is smaller than the distance between adjacent light sources mounted in rows on one surface of the board. Is.

  Since the light source unit 100 of the present embodiment has the notch 195 formed in the frame portion 110 and thus has the non-mounting surface side creepage distance Lb on the non-mounting surface side of the substrate 120b, it may be a lightning surge that enters from the outside. It is possible to improve resistance to electrical insulation against external noise. For this reason, the possibility that the light emitting element 120a is damaged by external noise or the performance is deteriorated is reduced.

  Further, since the light source unit 100 of the present embodiment can obtain the creepage distance Ln equal to or larger than the reference dimension Lth by adjusting the creepage distance Lb on the non-mounting surface side, that is, Lth ≦ Ln = Ls + T + Lb, The light emitting element 120a can be disposed close to the edge of the substrate 120b in the longitudinal direction, and the brightness on the edge side in the longitudinal direction can be improved. Further, in the light source unit 100 of the present embodiment, when a plurality of light source units 100 are connected in the longitudinal direction, the brightness in the entire longitudinal direction including the connecting portion can be made uniform.

Further, in the light source unit 100 of the present embodiment, the notch 195 can reduce the amount of the frame portion 110 used, which leads to weight reduction and material cost reduction.
Further, the light source unit 100 of the present embodiment can obtain the creepage distance Ln equal to or larger than the reference dimension Lth by adjusting the creepage distance Lb on the non-mounting surface side, that is, Lth ≦ Ln = Ls + T + Lb. It is not necessary to provide an insulating member such as an insulating sheet, which leads to weight reduction and material cost reduction.

*** Other configurations ***
In the present embodiment, the notch is formed at the end portion in the longitudinal direction of the frame portion, but it may be formed at the side portion of the frame portion without being limited to the end portion in the longitudinal direction.
Further, although the long lighting device is described in this embodiment, the present embodiment can be applied to a long lighting device. Specifically, even when a substrate having a circular shape, a substantially square shape, or a substantially regular polygonal shape is attached to the frame portion, the frame edge portion of the frame portion is set so that the creepage distance from the conductive portion at the peripheral portion of the substrate satisfies the reference dimension Lth. You may form a notch in it. That is, in the frame portion, a portion of the peripheral portion of the substrate where the value obtained by adding the distance Ls to the conductive portion such as the light emitting element and the thickness dimension T of the substrate is smaller than the reference dimension Lth overlaps the notch of the frame portion. The substrate may be attached in this state.

FIG. 35 is a diagram illustrating a modified example of the present embodiment.

As shown in FIGS. 2 and 3 and FIGS. 30 to 33, the light source unit 100 includes a cover 130 that covers the elongated substrate 120b on which the light emitting element 120a is mounted.
The cover 130 includes a cover body 132 that covers the irradiation side of the substrate 120b, and a cover end portion 135 that covers the longitudinal end portion of the cover body 132.
The lighting fixture 200 also includes an elongated recess 211 to which the light source unit 100 is attached.
The cover end portion 135 includes an end facing portion 1351 that faces a recess end portion 2111 that is an end portion in the longitudinal direction of the recess 211 with the light source unit 100 attached to the recess 211. The end facing portion 1351 has a cover inclined portion 1352 that is inclined in a direction away from the recess 211. The recessed portion 211 is an example of the light source attachment portion 201 to which the light source unit 100 is attached. Further, the recessed end portion 2111 is an example of an end portion in the longitudinal direction of the light source mounting portion 201 to which the end facing portion 1351 is directed. That is, the cover end portion 135 includes the end facing portion 1351 that faces the recess end portion 2111 that is the end portion in the longitudinal direction of the light source mounting portion 201 with the light source mounting portion 201 mounted on the light source mounting portion 201. The end facing portion 1351 has a cover inclined portion 1352 that is inclined in a direction away from the light source mounting portion 201.

  The cover end portion 135 includes an end surface portion 1354 that is a portion that closes the end portion of the cover 130, and an end facing portion 1351 that faces the recess end portion 2111. In the vicinity of the boundary between the end surface portion 1354 and the end facing portion 1351, there is a cover inclined portion 1352 formed so that the end facing portion 1351 gradually separates from the recess end portion 2111 toward the end portion in the longitudinal direction. It is formed. That is, the cover inclined portion 1352 is a portion in which the end facing portion 1351 is gradually inclined toward the irradiation side toward the end portion side in the longitudinal direction. The cover inclined portion 1352 is inclined toward the irradiation side while forming a gentle curved surface.

*** Explanation of the effect of this embodiment ***
Although the present embodiment has been described using the illumination device 10 and the end portion of the light source unit 100 according to the first embodiment, the amount of expansion and contraction of the cover 130 increases in the case of the light source unit 100x having a longer longitudinal dimension. . 34 and 35, description will be given using the lighting device 10x and the lighting fixture 200x according to the second embodiment. This embodiment can be applied to either the configuration of the first embodiment or the configuration of the second embodiment.

As shown in FIG. 34, in the lighting device 10x, the cover 130 can be extended by a clearance Lc in the longitudinal direction between the lighting fixture 200x and the light source unit 100x.

When the cover 130 is contracted by Ll or more, the corner portion of the end facing portion 1351 of the cover 130 may be caught on the peripheral edge of the recess end portion 2111 or the like. When the cover 130 extends again, the cover 130 may be damaged. Particularly, when the cover 130 is exposed to a cold environment, the amount of shrinkage increases.
According to the cover 130 of the present embodiment, since the cover inclined portion 1352 is formed on the end facing portion 1351 of the cover end portion 135, the cover is inclined in the process of deforming from the state of being greatly contracted to the direction of extending again. The end 135 is less likely to get caught in the lighting fixture 200.
As shown in FIG. 34, since the cover inclined portion 1352 is inclined toward the irradiation side by the angle θ with respect to the concave end portion 2111, the corner portion of the end facing portion 1351 of the cover 130 is the peripheral edge of the concave end portion 2111. Hard to get caught in.
