First, the light source unit 100 will be described.

As shown in FIGS. 1 and 2, the light source unit 100 includes, for example, a tubular housing 101, a first end 102 that is one end of the housing 101, and a second end that is the other end of the housing 101. and end 103 . Further, the light source unit 100 accommodates a light source substrate 221 in which a light emitting element 222 such as an LED is provided as a light source. The light source unit 100 is held by, for example, three fixtures 150 and fixed to the mounting object W by the fixtures 150 . This attachment target W is, for example, a ceiling, a signboard, a lighting used for a showcase, or the like. The details of the first end portion 102 and the second end portion 103 will be described later in the description of the connection of the two light source units 100 .

The housing 101 has, for example, a flat portion 201, a first protrusion 202, and second protrusions 203a and 203b. Flat portion 201 , first protrusion 202 , and second protrusions 203 a and 203 b each extend in the longitudinal direction of housing 101 . The outer shape of the housing 101 can also be regarded as the outer shape of the light source unit 100 .

The flat portion 201 has, for example, a flat surface on the outer peripheral surface side of the housing 101 . Furthermore, the flat surface of the flat portion 201 is provided with, for example, a groove 208 extending in the longitudinal direction.

For example, as shown in FIG. 2, the first projecting portion 202 has a cross section projecting in a direction that intersects the direction along the flat portion 201 . Also, the first projecting portion 202 gradually widens from its top portion downward in FIG. Furthermore, inside the first projecting portion 202 , for example, a light source board 221 is provided so as to extend in the longitudinal direction of the housing 101 . For example, a plurality of light emitting elements 222 are provided on the light source substrate 221 so as to be aligned in the longitudinal direction of the light source substrate 221 . The light emitting element 222 is provided so as to face the first projecting portion 202 . Furthermore, substrate supporting portions 221a and 221b for supporting the light source substrate 221, for example, are provided on the inner peripheral surface of the first protruding portion 202 so as to extend in the longitudinal direction. These 221 a and 221 b are recesses, for example, into which the edges of the light source substrate 221 are detachably inserted, and fix the light source substrate 221 inside the first projecting portion 202 . The first projecting portion 202 transmits light from the light emitting element 222 to the outside. Thereby, the light source unit 100 functions as illumination.

The second projecting portions 203a and 203b project from the first projecting portion 202 to both sides in the direction along the flat portion 201 (horizontal direction in FIG. 2). More specifically, the second projecting portions 203a and 203b include inclined surfaces 231a and 231b that extend further from the lower portion of the first projecting portion 202 in a direction along the flat portion 201 (horizontal direction in FIG. 2), and flat surfaces. and side portions 232 a and 232 b that stand up from both ends of the portion 201 .

Next, the fixture 150 will be described with reference to FIGS. 1, 2 and 3. FIG.

The fixture 150 is a member for attaching the light source unit 100 to the attachment target W, for example. For example, as shown in FIG. 1, the fixtures 150 are attached to the light source unit 100 at the first end portion 102 side, the second end portion 103 side, and the central portion. It should be noted that the mounting position and number of the mounting fixtures 150 are not limited to this. The fixture 150 is formed, for example, by punching, bending, or the like from a plate-like metal.

The fixture 150 has a flat plate portion 251, standing portions 252a and 252b, bent portions 253a and 253b, holding portions 254a and 254b, and connecting portions 356a and 356b.

For example, when the light source unit 100 is attached, the flat plate portion 251 contacts the flat portion 201 of the light source unit 100 to support the light source unit 100 . Then, the flat plate portion 251 comes into contact with the object W to be attached when it is attached to the object W to be attached.

In addition, the flat plate portion 251 has a projecting portion 258 that projects toward the surface on which the light source unit 100 is mounted. The projecting portion 258 is provided so as to extend in the longitudinal direction of the flat plate portion 251 . The longitudinal direction of the light source unit 100 and the longitudinal direction of the fixture 150 (flat plate portion 251) are substantially parallel when the light source unit 100 is attached to the fixture 150. described as a direction.

When the light source unit 100 is attached to the fixture 150 , the protrusion 258 is fitted into the groove 208 of the flat portion 201 of the light source unit 100 to support the light source unit 100 . It should be noted that in the case where the projecting portion 258 is not provided, the light source unit 100 is supported by the flat plate portion 251 coming into contact with the flat portion 201 .

The standing portions 252a and 252b, for example, face each other and stand from both ends of the flat plate portion 251. As shown in FIG. More specifically, the standing portions 252a and 252b are raised from both ends of the flat plate portion 251 in a direction perpendicular to the longitudinal direction. The standing portions 252a and 252b are, for example, plate-shaped.

When the light source unit 100 is attached to the fixture 150 , the standing portions 252 a and 252 b abut on the second projecting portions 203 a and 203 b of the light source unit 100 to support the light source unit 100 . More specifically, the standing portions 252a and 252b abut on the side portions 232a and 232b of the second projecting portions 203a and 203b to support the light source unit 100. As shown in FIG. That is, the distance between the standing portions 252a and 252b is approximately equal to the distance between the side portions 232a and 232b of the light source unit 100 (the width in the direction perpendicular to the longitudinal direction of the flat portion 201).

The bending portions 253a and 253b are bent from the tips of the standing portions 252a and 252b standing from the flat plate portion 251 toward the space sandwiched between the standing portions 252a and 252b. Also, the bent portions 253a and 253b are elastically deformable. Openings 355a and 355b are provided in the bent portions 253a and 253b. By providing the openings 355a and 355b, the elastic force of the bent portions 253a and 253b can be adjusted and, for example, the bent portions 253a and 253b can be elastically deformed. Alternatively, the openings 355a and 355b are not provided, and the bent portions 253a and 253b are made thinner than the flat plate portion 251 and the standing portions 252a and 252b, or a plurality of slits are provided in the bent portions 253a and 253b. By doing so, it is possible to adjust the elastic force of the bent portions 253a and 253b in the same manner as the openings 355a and 355b.

In particular, when the fixture 150 is manufactured from a plate-shaped member such as a metal plate by punching and bending, the bent portions 253a and 253b are formed with the same thickness as the other portions. It may be difficult to elastically deform because the rigidity is too high when it is attached. On the other hand, by providing openings or the like in the bent portions 253a and 253b as described above, the elastic force is adjusted, and the light source unit 100 can be easily attached to the fixture 150. FIG.

The holding portions 254a and 254b extend downward from the bent portions 253a and 253b in the space sandwiched between the rising portions 252a and 252b. More specifically, the holding portions 254a and 254b are flat plates extending from the bent portions 253a and 253b, and are inclined with respect to the standing portions 252a and 252b.

The holding portions 254a and 254b abut on the second projecting portions 203a and 203b of the light source unit 100 to support the light source unit 100 when the light source unit 100 is attached to the fixture 150 . More specifically, the tip portions of the holding portions 254a and 254b contact the inclined surfaces 231a and 231b of the second projecting portions 203a and 203b of the light source unit 100, thereby supporting the light source unit 100. FIG. Furthermore, when the light source unit 100 is to be removed from the light source unit 100 attached to the fixture 150, the holding portions 254a and 254b are, for example, removed upward in FIG. In this case, it is possible to prevent the tips of the holding portions 254a and 254b from being caught by the second projecting portions 203a and 203b and the light source unit 100 from being easily removed.

The connecting portions 356a and 356b extend, for example, in a direction orthogonal to the longitudinal direction of the flat plate portion 251. As shown in FIG. Also, the connecting portions 356 a and 356 b are provided on a diagonal line with respect to the flat plate portion 251 . Connection holes 357a and 357b are provided in the connection portions 356a and 356b. The fixture 150 is attached to the object W to be attached via the connection holes 357a and 357b, for example, by screws or the like. Note that the configuration for attaching the fixture 150 to the attachment target W is not limited to this.

Here, the state in which the light source unit 100 is attached to the fixture 150 will be further described.

When the light source unit 100 is attached to the fixture 150, as shown in FIG. 2, at least the flat portion 201 of the light source unit 100 is in contact with the flat plate portion 251 of the fixture 150, and the second protrusions 203a and 203b are in contact with each other. It is held by the fixture 150 by contacting the holding parts 254 a and 254 b of the fixture 150 . More specifically, in the light source unit 100, the protrusions 258 of the flat plate portion 251 are fitted into the grooves 208 of the flat portion 201 and come into contact with each other, and the holding portions 254a are attached to the inclined surfaces 231a and 231b of the second protrusions 203a and 203b. · It is held by the fixture 150 by abutting the tip of 254b.

Further, the light source unit 100 is more stably held by the fixture 150 by the contact of the second protrusions 203a and 203b with the standing parts 252a and 252b. More specifically, the light source unit 100 is more stably held by the fixture 150 by abutting the side surfaces 232a and 232b of the second projections 203a and 203b against the facing surfaces of the upright portions 252a and 252b. . In particular, by making the side surface portions 232a and 232b flat, the light source unit 100 is held by the fixture 150 more stably than the flat plate-like standing portions 252a and 252b.

Furthermore, the distance from the flat plate portion 251 to the bent portions 253a and 253b and the distance from the flat plate portion 251 to the light source substrate 221 when the light source unit 100 is attached to the fixture 150 are made substantially the same, or It is preferable to make the distance from 251 to the light source substrate 221 longer than the distance from the flat plate portion 251 to the bent portions 253a and 253b. Accordingly, it is possible to prevent the light from the light emitting element 222 in the light source unit 100 held by the fixture 150 from being blocked by the fixture 150 .

Next, an example of attaching the light source unit 100 to the fixture 150 and an example of removing the light source unit 100 from the fixture 150 will be described.

First, as shown in FIG. 4(a), one of the second projecting portions 203b of the light source unit 100 is inserted between the holding portions 254a and 254b of the fixture 150. Then, as shown in FIG.

Next, as shown in FIG. 4B, the other second projecting portion 203a of the light source unit 100 is pushed downward into the space between the standing portions 252a and 252b. As a result, the bending portions 253a and 253b are pushed by the light source unit 100 and elastically deformed, and the holding portions 254a and 254b are pushed toward the standing portions 252a and 252b.

Then, the light source unit 100 is further pushed into the space between the standing portions 252a and 252b. As a result, as shown in FIG. 4C, the holding portions 254a and 254b pushed by the light source unit 100 return to their original shapes due to the elastic force of the bending portions 253a and 253b, and the light source unit 100 is attached to the fixture 150. be worn. At this time, when the bent portions 253a and 253b return to their original shapes due to the elastic force, the tips of the holding portions 254a and 254b move along the inclined surfaces 231a and 231b of the second projecting portions 203a and 203b. Therefore, the contact between the holding portions 254a and 254b and the second projecting portions 203a and 203b can be maintained.

When removing the light source unit 100 from the fixture 150, for example, a flat-blade screwdriver is inserted between the first projecting portion 202 and the holding portion 254b shown in FIG. push downwards. As a result, the protrusion 258 serves as a fulcrum, and the second protrusion 203b is lowered into the gap 401 between the flat portion 201 and the flat plate portion 251, and the holding of the light source unit 100 by the holding portion 254b is released. At this time, the second projecting portion 203a rises upward with the projecting portion 258 serving as a fulcrum.

Next, a flat-blade screwdriver is further pushed into the gap 401 along, for example, the upright portion 252b, and the tip of the flat-blade screwdriver is hooked on the lower portion of the second protruding portion 203b and pushed upward. As a result, the protrusion 258 serves as a fulcrum, causing the second protrusion 203a to descend downward, and at the same time, the second protrusion 203b to rise. Then, the second protruding portion 203b is pushed upward from the holding portion 254b, and the light source unit 100 can be removed from the fixture 150. As shown in FIG.

In this way, especially by providing the protrusion 258 , the light source unit 100 can be easily removed from the fixture 150 . In addition, since the openings 355a and 355b are provided as described above and the elastic force of the bent portions 253a and 253b is adjusted, the holding portions 254a and 254b can be elastically deformed more easily, and the light source unit by the holding portions 254a and 254b can be easily adjusted. 100 can be released. Note that even if the protrusion 258 is not provided, the light source unit 100 can be removed by similarly inserting, for example, a flat-blade screwdriver or the like into the lower portion of the second protrusion 203b.

Next, a case of connecting the light source units 100A and 100B will be described. FIG. 5 is a diagram showing an example of a state in which two light source units 100A and 100B are connected. 6 is a sectional view taken along the line VI-VI in FIG. 5. FIG. Note that, in the present embodiment, the light source unit 100A and the light source unit 100B have the same configuration, and they may be collectively referred to as the light source unit 100 as well. Also, wiring is omitted in FIG.

The light source unit 100 has, for example, a first end 102 and a second end 103, as shown in FIGS.

The first end portion 102 has, for example, a first connecting portion 501 and a wiring 520 .

The second end 103 has, for example, a second connecting portion 510 .

The first connecting portion 501 is, for example, a convex portion that protrudes in the longitudinal direction of the housing 101 from the end portion of the housing 101 . The second connecting portion 510 is, for example, a concave portion that fits with the first connecting portion 501 so as to extend in the longitudinal direction of the housing 101 from the end portion of the housing 101 . By fitting the first connecting portion 501 and the second connecting portion 510, the two light source units 100A and 100B are connected. Note that the first connecting portion 501 and the second connecting portion 510 are not limited to the above configuration, and may have any configuration as long as they can be connected.

Further, inside the first connecting portion 501, for example, as shown in FIG. The light source board 221 provided with the light emitting element 222 is, for example, a part of the light source board 221 provided with the light emitting element 222 provided inside the housing 101 . On the other hand, at the second end portion 103 , the light source substrate 221 extends to the vicinity of the end portion of the housing 101 . Accordingly, when the first connecting portion 501 and the second connecting portion 510 are connected, the light source substrate 221 arranged on the first connecting portion 501 and the light source substrate 221 extending to the vicinity of the second end portion 103 are separated. are placed in close proximity to each other. Therefore, the two light source units 100A and 100B that are connected can be made to emit light seamlessly. The first connecting portion 501 and the second connecting portion 502 are made of a material that transmits light from the light emitting element 222, for example.

Further, when the light source units 100A and 100B are connected, the distance between the light emitting element 222 closest to the light source unit 100B in the light source unit 100A and the light emitting element 222 closest to the light source unit 100A in the light source unit 100B is a predetermined value. The following are preferable. This predetermined value is, for example, a distance that does not darken the seam between the first connecting portion 501 and the second connecting portion 502 when the light source units 100A and 100B are connected to emit light.

Furthermore, in the light source substrate 221, for example, it is preferable to arrange the plurality of light emitting elements 222 along the longitudinal direction of the light source substrate 221 and arrange the distances between adjacent light emitting elements 222 at approximately the same distance. This allows the light source unit 100A to emit light with uniform brightness over the longitudinal direction. Then, for example, by setting the predetermined value substantially equal to the distance between the adjacent light emitting elements 222, the seam between the first connecting portion 501 and the second connecting portion 502 can be set to the other portion of the light source unit. Brightness can be approached. This makes it possible to make the joint between the first connecting portion 502 and the second connecting portion 510 inconspicuous. In particular, the distance between the light emitting element 222 closest to the light source unit 100B in the light source unit 100A and the light emitting element 222 closest to the light source unit 100A in the light source unit 100B is By making the distance substantially the same, when the light emitting units 100A and 100B are connected, the brightness between the light emitting units 100A and 100B can be made the same brightness as the other parts, so that there is no seam. It can emit light.

Furthermore, when the light source units 100A and 100B are connected, the light emitting elements 222 provided in each of the light source units 100A and 100B are preferably arranged in a line. This allows the light source units 100A and 100B to emit light more integrally.

The wiring 520 is for, for example, supplying power to the light emitting elements 222 provided on the light source substrate 221 . For example, a connector connected to a power supply is provided at the tip of the wiring 520 . For example, as shown in FIG. 5, the wiring 520 is a portion where the first connecting portion 501 and the second connecting portion 510 are connected at the first end portion 102 of the connected light source units 100A and 100B, that is, the first It is pulled out from a portion of the connecting portion 501 other than the portion that contacts the second connecting portion 510, or is pulled out from the end face of the housing 101 where the first connecting portion 501 protrudes. In other words, the wiring 520 is pulled out from the housing 101 side, for example, from the portion of the first connecting portion 501 that contacts the second connecting portion 510 . More specifically, the wiring 520 is drawn out via the lead-out portion 530, for example. The drawer portion 530 is provided, for example, at a portion of the first connecting portion 501 other than the portion connected to the second connecting portion 510 or at an end portion of the housing 101 . Accordingly, when the light source units 100A and 100B are connected, the wiring 520 does not interfere with light emission, and the light source units 100A and 100B can be caused to emit light seamlessly. In addition, it is preferable that the lead-out portion 530 is provided on the opposite side of the surface of the light source substrate 221 on which the light emitting elements 222 are provided, for example. As a result, the wiring 520 is pulled out in the direction opposite to the direction in which the light from the light emitting element 222 is emitted, and the wiring 520 can be prevented from blocking the light from the light emitting element 222 .
