DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] <Summary> In one embodiment, an illumination device has a mounting member attached to a base member having a light source on its front side, and the base member has an insertion groove portion into which an attachment portion of the mounting member is inserted, and a crimp portion formed in a portion of the insertion groove portion corresponding to the attachment portion that is inserted. In a lighting device according to another aspect, the mounting portion has a recess in a portion corresponding to the crimped portion, whereby the mounting member can be firmly attached to the base member. In the lighting device according to another aspect, the recess has a portion that is shaped like an arc when viewed from the crimping direction of the insertion groove portion, thereby improving adhesion between the recess and the crimping portion. In a lighting device according to another embodiment, the base member has a flat portion on which the light source is disposed, the mounting member is a member for mounting a power supply circuit for the light source to the base member, the power supply circuit includes a power supply board on which electronic components for forming a circuit are mounted parallel to the flat portion, the mounting member has a standing plate portion standing on the flat portion, the standing plate portion has a first support portion extending along a front surface of the power supply board to support the front surface, and a second support portion extending toward the rear surface of the power supply board to support the rear surface, the second support portion being configured with an elastic inclined piece that extends in the front-rear direction of the power supply board so as to move away from the standing plate portion as it approaches the rear surface. This allows the power supply board to be mounted by placing it and pushing it into the base member, simplifying the installation work of the power supply board.

[0009] In another aspect, the lighting device includes a box-shaped insulating rear case that covers the power supply board from the back side, and a box-shaped power supply cover that is attached to the mounting member and covers the back side of the insulating rear case, the power supply cover has an extension piece on the side plate portion that extends away from the side plate portion as it moves away from the power supply board, and the insulating rear case has a notch that opens to the power supply board side at a position on the side plate portion that corresponds to the extension piece of the power supply cover. This makes it easy to assemble the power supply cover and the insulating rear case. In a lighting device according to another embodiment, the power supply cover has a protruding portion on the side plate portion that protrudes inward, and the mounting member has a recess on the upright plate portion into which the protruding portion engages. This makes it possible to easily mount the power supply cover to the base member. The power supply cover can be mounted to the base without using a dedicated member.

[0010] In the lighting device according to another aspect, an end portion of the side plate portion of the power supply cover facing the mounting member on the flat portion side spreads outward from the power supply cover, thereby making it possible to easily attach the power supply cover to the mounting member without the end portion of the power supply cover getting caught on the mounting member. In a lighting device according to another embodiment, the light source unit is configured by mounting a plurality of LED elements on an LED board having one or more through holes, and the base member has a light source support portion supporting the LED board slidably in a first direction, a first through hole formed in the flat portion at a position corresponding to the one or more through holes of the LED board, and one or more second through holes formed in the flat portion outside the area where the LED board is disposed, and a positioning member disposed on the back side of the base member integrally having one or more first convex portions protruding from the first through hole to the front side of the flat portion and one or more second convex portions protruding from the second through hole to the front side of the flat portion so as to be movable forward and backward, thereby restricting the movement of the LED board in the first direction.

[0011] <Embodiment> 1. Lighting system The lighting system 1 is an elongated LED base light that is attached to a mounting surface such as a ceiling. The lighting system 1 includes a fixture 3 that is attached to the mounting surface, and a lighting device 5 that is detachably attached to the fixture 3, as shown in Figs. 1 and 2. In the lighting system 1, the side from which light is emitted is referred to as the front side, and may be simply referred to as the "front side." In the lighting system 1, the side on which the installation surface is located is referred to as the back side, and in the lighting device 5, the side on which the installation surface and the fixtures 3 are located is referred to as the back side, and may be simply referred to as the "back side." The long side of the long lighting system 1 is sometimes simply referred to as the "longitudinal direction" or the "longitudinal direction of the device," and the short side of the lighting system 1 is sometimes simply referred to as the "short side direction" or the "short side direction of the device." Each part will be explained below.

[0012] 2. Equipment The following description will be mainly made with reference to FIG. 1 and FIG. The fixture 3 is fixed to the mounting surface by means of, for example, a hanging bolt 21 or the like. The fixture 3 includes a terminal block 31 for supplying commercial power to the lighting device 5, and a pair of fixture-side mounting fixtures 33 for detachably mounting the lighting device 5, in a fixture body 35. The fixture body 35 is provided with a through hole for the hanging bolt 21, a through hole for the power supply cable 23, and through holes for fixing the terminal block 31 and the fixture-side mounting fixtures 33, etc.

[0013] 3. Lighting equipment 5 (1) Overall This will be explained with reference to FIG. 2 and FIG. The lighting device 5 includes at least a long base member 50, a light source unit 51 provided on the front side of the base member 50, a front cover 52 covering the light source unit 51 from the front side, an end cover 53 attached to the longitudinal ends of the base member 50 and the front cover 52, a power supply unit 54 supplying lighting power to the light source unit 51, and a mounting fixture 57 for detachably mounting the lighting device 5 to the fixture 3. The lighting device 5 here has a wireless communication unit 58 on the base member 50 for wirelessly communicating with a lighting control device (controller) not shown. Here, the power supply mounting member (540) for mounting the power supply unit 54 to the base member 50 corresponds to an example of a mounting member of the present invention, and the mounting fixture 57 and the end cover 53 correspond to an example of a mounting member of the present invention. Each part will be explained below.

[0014] (2) Base material The explanation will be mainly given with reference to FIG. The base member 50 has a flat portion 501 on which the light source unit 51 is disposed, a light source support portion 502 that supports the light source unit 51 so as to be slidable in the longitudinal direction, a front cover support portion 503 for supporting the front cover 52, an end cover attachment portion 504 (not shown) for attaching the end cover 53, a power supply attachment portion 505 for attaching the power supply unit 54, and a attachment attachment portion 506 for attaching the attachment 57. The cross-sectional shape of the base member 50 is constant in the longitudinal direction, and an aluminum extrusion molding or the like can be used.

[0015] (2-1) Flat area The flat portion 501 has a rectangular plate shape, and its longitudinal direction coincides with the longitudinal direction of the device. A virtual line passing through the approximate center in the short side direction and extending in the longitudinal direction is set as a central axis, which is referred to as the central axis of the base member 50 or simply the central axis. The base member 50 has an "L"-shaped rear L-shaped portion 507 that extends toward the central axis from both ends of the short side of the flat portion 501 to the rear side over the entire length in the longitudinal direction. The portion of the rear L-shaped portion 507 that extends toward the central axis with a gap between it and the flat portion 501 is referred to as a rear extending portion 507a. The flat portion 501 and the rear L-shaped portion 507 form an insertion groove 508 into which a power supply mounting member 540 for mounting the power supply unit 54, a mounting fixture 57, and a mounting portion of the end cover 53 are inserted. The power supply mounting member 540, the mounting fixture 57, and the end cover 53 are fixed using this insertion groove 508.

[0016] (2-2) Light source support part The light source support part 502 has a pair of front-side L-shaped parts 502a that extend from the surface of the flat part 501 to the front side and then extend toward the central axis. The pair of front-side L-shaped parts 502a are provided at two positions that correspond to the short-side dimension of the light source unit 51 and are provided over the entire length in the longitudinal direction. The pair of front-side L-shaped parts 502a and the flat part 501 form a light source insertion groove part into which the light source unit 51 is inserted from the longitudinal direction. This makes it possible to support the light source unit 51 without using screws or the like.

[0017] (2-3) Front cover support The front cover support part 503 has a pair of J-shaped parts 503a that extend from the surface of the flat part 501 to the front side, then extend toward the opposite side of the central axis, and then further extend to the back side. The pair of J-shaped parts 503a are provided in two locations that correspond to the short-side dimension of the front cover 52, and are provided over the entire length in the longitudinal direction. The pair of J-shaped parts 503a and the flat part 501 form a front cover insertion groove into which the opening side end part 523 of the front cover 52 is inserted from the longitudinal direction. This makes it possible to support the front cover 52 without using screws or the like.

[0018] (2-4) End cover attachment part The end cover 53 has a rear fitting portion 532 (enlarged view in FIG. 3) that can be inserted into the insertion groove portion 508 of the base member 50. The end cover mounting portion 504 mounts (fixes) the end cover 53 by recessing the portions of the rear extension portion 507a of the rear L-shaped portion 507 that face the end ends 532b of the rear fitting portion 532 (see the enlarged view of FIG. 3) into the end portion 532b side (front side) with both end portions 532b of the rear fitting portion 532 inserted and positioned in the insertion groove portion 508. In other words, the end cover mounting portion is composed of a crimping (clamping) portion formed by crimping the rear extension portion 507a of the rear L-shaped portion 507. In addition, the end cover 53 is attached to the base member 50, thereby restricting the movement of the front cover 52 in the longitudinal direction. That is, the front cover 52 is attached to the base member 50 side.

[0019] (2-5) Power supply attachment section As shown in Fig. 4(a), the power supply unit 54 is attached to the base member 50 via a power supply mounting member 540. That is, an end 540c (see Fig. 8) of an opposing plate portion 540a of the power supply mounting member 540 is inserted into an insertion groove portion 508 between the rear L-shaped portion 507 and the flat portion 501 from the longitudinal end, whereby the power supply mounting member 540 is supported by the flat portion 501 so as to be slidable only in the longitudinal direction. The power supply mounting portion 505 mounts the power supply mounting member 540 by recessing a portion of the rear extension portion 507a of the rear L-shaped portion 507 facing the end portion 540c of the power supply mounting member 540 into the end portion 540c side (front side) with the power supply mounting member 540 positioned in the longitudinal direction relative to the base member 50. In other words, the deformed rear L-shaped portion 507 recesses into a recess (notched portion) 540d of the power supply mounting member 540, thereby fixing the longitudinal position of the power supply mounting member 540. The power supply mounting portion 505 is composed of a crimping (clamping) portion formed by crimping the rear extension portion 507a of the rear L-shaped portion 507.

[0020] (2-6) Mounting part for attachment The mounting fixture 57 is attached to the base member 50 as shown in Fig. 4(b). That is, an end 572a (see Fig. 13) of an opposing plate portion 572 of the mounting fixture 57 is inserted into an insertion groove portion 508 between the rear L-shaped portion 507 and the flat portion 501 from the longitudinal end, whereby the mounting fixture 57 is supported by the flat portion 501 so as to be slidable only in the longitudinal direction. The mounting fixture attachment portion 506 attaches the mounting fixture 57 by recessing a portion of the rear extension portion 507a of the rear L-shaped portion 507 that faces the end portion 572a of the mounting fixture 57 into the end portion 572a (front side) with the mounting fixture 57 positioned in the longitudinal direction relative to the base member 50. In other words, the deformed rear L-shaped portion 507 recesses into the through hole 572b of the mounting fixture 57, thereby fixing the longitudinal position of the mounting fixture 57. The mounting fixture attachment portion 506 is composed of a crimping (clamping) portion formed by crimping the rear extension portion 507a of the rear L-shaped portion 507.

[0021] (3) Light source unit The explanation will be mainly given with reference to FIG. The light source unit 51 includes an LED board 511 and a plurality of LED elements 513. The base member 50 includes the LED elements 513, which are light sources, mounted on the LED board 511. The LED board 511 has a rectangular shape that is elongated in the longitudinal direction of the base member 50. The light source unit 51 is supported at both ends in the lateral direction of the LED board 511 by a pair of front L-shaped portions 502a of the base member 50. The positioning of the light source unit 51 and the connection to the power supply unit 54 will be described later.

[0022] (4) Front cover The explanation will be mainly given with reference to FIG. The front cover 52 is made of a light-transmitting resin material. The cross-sectional shape of the front cover 52 is constant in the longitudinal direction. The cross-sectional shape is a wide "U" shape with an opening on the back side. The front cover 52 has an opening side end 523 in the lateral direction supported by the front cover support part 503 so as to be slidable in the longitudinal direction. More specifically, the opening side end 523 of the front cover 52 is inserted from the longitudinal direction into a front cover insertion groove part formed by a flat part 501 and a J-shaped part 503a and supported. The opening side end 523 of the front cover 52 has a bent part 523a that bends to the front side, and the dimension of the bent part 523a in the front-back direction is larger than the distance of the gap between the J-shaped part 503a and the flat part 501. This makes it possible to prevent the front cover 52 from coming off the front cover support part 503 in the lateral direction. The longitudinal ends of the front cover 52 come into contact with end covers 53 attached to the base member 50, so that longitudinal movement is restricted.

[0023] (5) End cover The following description will be given mainly with reference to the enlarged view of FIG. The end cover 53 has an end cover main body 530 that covers the end opening of a cylindrical body formed by the base member 50 and the front cover 52, a front fitting portion 531 that extends from the front peripheral edge of the end cover main body 530 and fits into the inner surface of the front cover 52, and a back fitting portion 532 that extends from the rear peripheral edge of the end cover main body 530 along the back surface of the base member 50, and both short end portions 532b of the back fitting portion 532 are fitted (inserted) into the insertion groove portion 508. The end cover 53 is attached to the base member 50 by inserting the end 532b of the rear fitting portion 532 into the insertion groove portion 508 and by a crimped portion (not shown) of the rear extension portion 507a of the rear L-shaped portion 507. The end of the rear fitting portion 532 has a recess, a through hole, and a cut portion 532a at a position corresponding to the crimped portion, so that the end cover 53 can be prevented from easily coming off the base member 50 in the longitudinal direction. The end 532 c of the rear fitting portion 532 of the end cover 53 is inserted into the insertion groove portion 508 of the base member 50 and serves as an attachment portion that is attached to the base member 50 .

[0024] (6) Power supply unit The power supply unit 54 generates lighting power and adjusts the lighting power according to instructions from the wireless communication unit 58. As shown in Figures 6 and 7, the power supply unit 54 comprises a power supply mounting member 540 attached to the base member 50, a power supply circuit 543 having a plurality of electronic components 541 mounted on a power supply board 542, and a power supply cover 544 that is detachably attached to the power supply mounting member 540 and covers the power supply circuit 543. The power supply unit 54 here includes an insulating case 545 for ensuring insulation of the power supply circuit 543. The insulating case 545 is made up of an insulating front case 546 on the base member 50 side and an insulating back case 547 on the power supply cover 544 side. Each part will be explained.

[0025] (6-1) Power supply mounting parts The following description will mainly use FIG. The power supply mounting member 540 is made by pressing a metal plate. There are a plurality of power supply mounting members 540 (for example, two) spaced apart in the longitudinal direction of the device. This allows the power supply circuit 543 to be supported in a stable state. The power supply mounting member 540 has an opposing plate portion 540a that faces the flat portion 501 of the base member 50, and an erect plate portion 540b that erects from the opposing plate portion 540a. Here, the erect plate portions 540b are provided in a pair at an interval in the short side direction of the device. The opposing plate portion 540a has a rectangular shape as a whole, and the dimension of the device in the short side direction corresponds to the distance between the pair of rear L-shaped portions 507 of the base member 50, as shown in Fig. 4(a). An end portion 540c in the short side direction of the opposing plate portion 540a is an attachment portion that is inserted into an insertion groove portion 508 of the base member 50 and attached to the base member 50. The power supply mounting member 540 has a recess (here, a cutout) 540d at a position corresponding to the position of the crimped portion of the rear extension portion 507a of the rear L-shaped portion 507 when the power supply mounting member 540 is mounted to the base member 50. This positions the power supply mounting member 540 in the longitudinal direction of the device. That is, the power supply mounting member 540 is mounted to the base member 50. In this manner, the power supply mounting member 540 is mounted to the base member 50 by crimping the rear extension portion 507a that constitutes the insertion groove portion 508, without using screws. Note that here, the recess (cutout) 540d is provided at approximately the center of the longitudinal direction of the device at the end portion 540c of the facing plate portion 540a.

[0026] 5B, the distance between the pair of standing plate portions 540b corresponds to the dimension in the short direction of the power supply board 542. That is, the power supply board 542 is disposed between the pair of standing plate portions 540b. The power supply mounting member 540 has a pair of first support parts 540e that extend along the surface of the power supply board 542 and support the surface of the power supply board 542, and a pair of second support parts 540f that extend to the back side of the power supply board 542 and support the back side of the power supply board 542. The first support parts 540e and the second support parts 540f are formed by bending a part of the standing plate part 540b. The second support portion 540f is configured by an inclined piece 540f that inclines so as to move away from the standing plate portion 540b as it approaches the back side of the power supply board 542 in the front-back direction. The inclined piece is also designated by the symbol "540f". The distance between the pair of inclined pieces 540f is configured to be expandable and contractible by the elastic deformation of the inclined piece 540f itself and the elastic deformation of the standing plate portion 540b. As a result, when attaching the power supply board 542 to the power supply mounting member 540, the power supply board 542 is disposed between the pair of standing plate portions 540b, and the power supply board 542 is pressed from the back side to the front side. After the power supply board 542 exceeds the inclined piece 540f, the inclined piece 540f returns to its original inclined state by the elastic force, and the power supply circuit 543 is fixed to the power supply mounting member 540.

[0027] (6-2) Power supply circuit 6 and 7, the power supply circuit 543 has an electronic component 541 and a power supply board 542. The power supply board 542 is supported by the power supply mounting member 540 in a state parallel to the flat portion 501 of the base member 50. The power supply circuit 543 has a connector 551 on the power supply board 542 for connecting to the terminal block 31 of the appliance 3. The terminal block 31 and the connector 551 are connected via a cable (not shown). The connector 551 is provided at an end of the power supply board 542 in the longitudinal direction as shown in FIG. 7, and is located outside the power supply cover 544 as shown in FIG. 2. This allows easy electrical wiring to the appliance 3 side. As shown in Fig. 9, the power supply board 542 is electrically connected to the LED board 511 via a conductive pin 552. As shown in Fig. 9 and Fig. 10, the conductive pin 552 is fixed by being inserted from the front side into a pin fixture 553 held by a holding member 554 that is detachably attached to the power supply board 542.

[0028] (6-2-1) Conductive pin The conductive pin 552 is formed by bending one end of a linear body (rod-shaped body) made of a single conductive material. One end is connected to the LED board 511, and the other end is connected to the power board 542. The conductive pin 552 has one end folded back into a "U" shape, and then the tip (one end) extends outward. That is, the conductive pin 552 has a folded back portion 552b folded back at one end, a horizontally extending portion 552a extending outward from one end of the folded back portion 552b, and a vertically extending portion 552c extending in the front-rear direction from the other end of the folded back portion 552b. The folded back portion 552b refers to the "U" shaped portion. Since the conductive pin 552 has the folded portion 552b, an assembly robot can grip the folded portion 552b when inserting the conductive pin 552 into the power supply board 542 from the LED board 511 side. At this time, since the horizontal extending portion 552a exists on one end side of the folded portion 552b, the portion where the assembly robot grips the folded portion 552b is on the front side of the LED element 513, and it is possible to prevent the assembly robot from coming into contact with the LED element 513. In addition, the horizontal extending portion 552a extending outward functions as a stopper when the conductive pin 552 is inserted.

[0029] The horizontal extension portion 552a of the conductive pin 552 is fixed to the LED substrate 511 by, for example, solder. At this time, since the vertical extension portion 552c of the conductive pin 552 is configured to be thinner than the through hole 511c of the LED substrate 511, the vertical extension portion 552c and the LED substrate 511 rarely come into contact with each other due to thermal expansion, and an excessive load is not applied to the connection portion between the LED substrate 511 and the conductive pin 552.

[0030] Furthermore, the temperatures of the base member 50 and the LED substrate 511 change by several tens of degrees due to changes in the environmental temperature of the place where the lighting device 5 is installed and heat generated by the LED substrate 511 and the like when the lighting device 5 is turned on. At this time, the base member 50 is made of a metal such as aluminum, whereas the LED substrate 511 is made of epoxy resin reinforced with glass fiber, and therefore has a different thermal expansion coefficient. The conductive pin 552 indirectly connects the base member 50 and the LED substrate 511, which have different thermal expansion coefficients, and is therefore subjected to stress due to a change in the longitudinal dimensions of the two members caused by the difference in thermal expansion coefficients. This stress is absorbed by the deformation of the folded portion 552b.

[0031] Here, the laterally extending portion 552a extends in a direction away from the vertically extending portion 552c of the conductive pin 552. Here, the laterally extending portion 552a extends in the longitudinal direction of the LED substrate 511. This ensures the length of the laterally extending portion 552a fixed to the LED substrate 511. Note that the conductive pin 552 is inserted from the front side through the through hole 511a (see FIG. 10) of the LED substrate 511 from the other end side, the through hole 501a (see FIGS. 6 and 7) of the flat portion 501 of the base member 50, and the pin insertion portion 554d of the holding member 554. A vertical extension portion 552 c of the conductive pin 552 is fixed to a conductive pin fixture 553 , and the pin fixture 553 is held by a holding member 554 so as to come into contact with a connection terminal of the power supply board 542 .

[0032] (6-2-2) Pin Fixture As shown in the enlarged views of FIG. 9 and FIG. 10, the pin fixing tool 553 has a fixing part for fixing the inserted conductive pin 552 and a connecting part for contacting the connecting terminal of the power supply board 542, which are integral with each other. The fixing part for the conductive pin 552 has a pair of pin fixing pieces 553a that can move closer and farther by elastic deformation. The space between the pair of pin fixing pieces 553a expands when the conductive pin 552 is inserted, and the inserted conductive pin 552 is fixed by the restoring force of the expanded pin fixing pieces 553a. Since the conductive pin is fixed by the pair of pin fixing pieces 553a in this way, the positional deviation of the through hole 542a of the power supply board 542 and the through hole 511a of the LED board 511 can be absorbed. The pair of pin fixing pieces 553a are adjacent to each other in the extension direction of the horizontal extension part 552a of the conductive pin 552. As a result, the influence caused by the difference in the thermal expansion coefficient between the base member 50 and the LED board 511 can be effectively absorbed, similar to the folded part 552b of the conductive pin 552. The pair of pin fixing pieces 553a are inclined so that the distance between the pin fixing pieces 553a becomes smaller along the insertion direction of the conductive pin 552 from the base portion 553b. In other words, the pair of fixing pieces 553a are configured in a V-shape. This allows the conductive pin 552 to be smoothly received between the pair of pin fixing pieces 553a.

[0033] There are two base parts 553b corresponding to the pair of pin fixing pieces 553a, and they extend from the base of the pin fixing pieces 553a in the extension direction of the horizontal extension part 552a of the conductive pin 552 (the longitudinal direction of the LED substrate 511). The two base parts 553b are connected by a connecting part 553c on both sides in a direction perpendicular to the direction in which the pair of pin fixing pieces 553a adjoin and the insertion direction of the conductive pin 552 (here, the short direction of the device). The connecting part 553c has a curved part 553d that curves so as to enter the through hole 542a of the power substrate 542 in the middle of the direction in which the pin fixing pieces 553a adjoin. Thereby, the interval between the pair of pin fixing pieces 553a can be expanded not only by the elastic deformation of the pin fixing pieces 553a but also by the elastic deformation of the curved part 553d, and various thicknesses of conductive pins 552 can be accommodated. 9(c), the curved portion 553d comes close to or abuts against the end face that constitutes the through hole 542a of the power supply board 542. This positions the pin fixing device 553 in the short side direction of the device. The connecting portion 553f extends in the longitudinal direction from the end of the base portion 553b or the coupling portion 553c in the longitudinal direction of the device. Here, the connecting portion 553f extends from the coupling portion 553c, and a step portion 553g formed between the connecting portion 553f and the coupling portion 553c fits into the through hole 542a of the power supply board 542. As a result, the pin fixing device 553 is positioned in the longitudinal direction of the device with the pin fixing piece 553a, the base portion 553b, and the coupling portion 553c disposed in the through hole 542a.

[0034] (6-2-3) Retaining member The holding member 554 is made of an insulating resin material. The holding member 554 is detachably attached to the power supply board 542. The holding member 554 includes a base portion 554a extending in the short-side direction of the power supply board 542 and facing the front surface of the power supply board 542, an extension portion 554b extending from an end portion of the base portion 554a in the short-side direction of the power supply board 542 to the rear side, and a protrusion portion 554c protruding from the tip of the extension portion 554b toward the other extension portion 554b. When the extension portion 554b is fitted into the cut portion 542c of the power supply board 542, the protrusion portion 554c engages with the rear surface of the power supply board 542. The holding member 554 has a pair of pin insertion portions 554d for inserting the conductive pin 552. The pin insertion portions 554d are provided on both sides of the base portion 554a in the longitudinal direction of the LED substrate 511. The pin insertion portions 554d are frustum-shaped with a narrow back side. The frustum shape here is a quadrangular pyramid shape, and a through hole for the conductive pin 552 is provided in the top wall at a position corresponding to between the pair of pin fixing pieces 553a of the pin fixing device 553. This allows the other end of the conductive pin 552 to be smoothly guided to the pin fixing pieces 553a. The holding member 554 has a base portion 554a and ribs 554f that reinforce the pair of pin insertion portions 554d. The ribs 554f are provided in pair, and are provided so as to be continuous with the base portion 554a and the pin insertion portions 554d on both sides thereof in the longitudinal direction of the LED board 511. The ribs 554f are provided so as to protrude from the rear side, and have convex portions 554g on the rear side that fit into the through holes 542b of the power supply board 542. This positions the holding member 554 with respect to the power supply board 542.

[0035] The holding member 554 has a function of holding the pin fixing device 553, and also a function of positioning the LED board 511, which is supported slidably relative to the base member 50, in the longitudinal direction. That is, the holding member 554 corresponds to an example of the positioning member of the present invention. The positioning member here has a function of holding the pin fixing device 553, but may have only the positioning function. The holding member 554 has a first convex portion 554h that is inserted through a first through hole 501b (see FIGS. 6 and 7) of the flat portion 501 of the base member 50 and fits into a recess or through hole 511b of the LED substrate 511, and a convex support portion 554j that supports the first convex portion 554h and is elastically deformable in the thickness direction of the flat portion 501 and the LED substrate 511. As a result, when the LED substrate 511 is slid in the longitudinal direction, the convex support portion 554j elastically deforms to the rear side, so that the first convex portion 554h abuts against the rear surface of the LED substrate 511, and when the LED substrate 511 slides and the through hole 511b of the LED substrate 511 is located at a position corresponding to the first convex portion 554h, the convex support portion 554j is restored to the front side, and the first convex portion 554h fits into the through hole 511b. As a result, the LED substrate 511 can be positioned without using screws or the like. Here, the through-holes 511b, the first convex portions 554h and the convex support portions 554j of the LED substrate 511 are multiple (two) in the short side direction of the LED substrate 511, and the convex support portions 554j extend along the long side direction of the LED substrate 511 from the base portions 554a.

[0036] The holding member 554 has a second protrusion 554k that protrudes from the second through hole 501c of the flat portion 501 of the base member 50 to the front side of the flat portion 501, and is integral with the first protrusion 554h and the protruding support portion 554j. The second protrusion 554k here is provided on both sides in the short side direction outside the LED substrate 511 with respect to the first protrusion 554h. That is, the holding member 554 has two first protrusions 554h spaced apart in the short side direction, and two second protrusions 554k on the outside side in the short side direction with respect to the two first protrusions 554h. The first protrusion 554h and the second protrusion 554k are connected by a protrusion forming portion 554n, and both ends in the short side direction of the LED substrate 511 in the protrusion forming portion 554n are connected to the protruding support portion 554j. As a result, during assembly, the LED substrate 511 is slid from the longitudinal end of the base member 50, and when the end face of the LED substrate 511 comes into contact with the first convex portion 554h, the second convex portion 554k protruding from the second through hole 501c of the base member 50 is pushed to the back side, thereby moving the first convex portion 554h to the back side, and the LED substrate 511 can be slid to a predetermined position. In addition, the first through hole 501b for the first convex portion 554h is provided within the area where the LED substrate 511 of the flat portion 501 of the base member 50 is arranged, and the second through hole 501c of the second convex portion 554k is provided outside the area where the LED substrate 511 of the flat portion 501 of the base member 50 is arranged.

[0037] (6-3) Insulation case The following description will be given mainly with reference to FIG. 6 and FIG. The insulating case 545 is for ensuring insulation between the metallic base member 50 and the power supply circuit 543, and is made of an insulating material such as a resin material. The insulating front case 546 has a bottom plate portion 546a facing the power supply board 542, and a long side plate portion 546b extending from a short side edge of the bottom plate portion 546a (an edge parallel to the longitudinal direction of the long power supply board 542) to the rear side. The insulating front case 546 is disposed between the power supply board 542 and the base member 50 or between the power supply board 542 and the power supply mounting member 540, as shown in FIG. 5(c). The bottom plate portion 546a is provided with a through hole 546c for the conductive pin 552, a through hole 546d for a first protrusion 554h of the holding member 554, a through hole 546e for a second protrusion 554k of the holding member 554, and the like. A through hole 546f is provided at the connecting portion between the bottom plate portion 546a and the long side plate portion 546b for a first support portion 540e that supports the power supply board 542 from the front side. A through hole 546g is provided in the long side plate portion 546b for a second support portion 540f that holds the power supply board 542 from the back side.

[0038] The insulating rear case 547 is box-shaped with an open front side. The insulating rear case 547 has a top plate portion 547a facing the power supply board 542, a long side plate portion 547b extending from a short-side edge (an edge parallel to the long side of the long power supply board 542) of the top plate portion 547a to the front side, and a short side plate portion 547c extending from a long-side edge (an edge parallel to the short side of the long power supply board 542) of the top plate portion 547a to the front side. The insulating rear case 547 is disposed between the power supply board 542 and the power supply cover 544 as shown in FIG. 5(a). The long side plate portion 547b is provided with a notch 547d or the like to avoid interference with the standing plate portion 540b of the power supply mounting member 540 (see FIG. 5(a)). The insulating rear case 547 is integrated with the power supply cover 544 during assembly to cover the power supply circuit 543. For this reason, the long side plate portion 547b has a notch 547f for engaging with the holding portion (extension piece) 544g of the long side plate portion 544b of the power supply cover 544. The connector 551 of the power supply board 542 is located outside the short side plate portion 547c of the insulating rear case 547.

[0039] (6-4) Power supply cover The following description will be given mainly with reference to FIG. 6 and FIG. The power supply cover 544 is box-shaped with an opening on the front side, and covers the power supply circuit 543 from the back side together with an insulating rear case 547 that covers the power supply circuit 543 from the back side. The power supply cover 544 has a top plate portion 544a facing the power supply board 542, etc., a long side plate portion 544b extending from the short-side edge (the edge parallel to the long-side direction of the long-shaped power supply board 542) of the top plate portion 544a to the front side, and short side plate portions 544c and 544d extending from the long-side edge (the edge parallel to the short-side direction of the long-shaped power supply board 542) of the top plate portion 544a to the front side. The long side plate portion 544b and the short side plate portion 544c extend to the vicinity of the flat portion 501 of the base member 50. The short side plate portion 544d is a short side plate portion on the side closer to the connector 551, and extends to the vicinity of the power supply board 542.

[0040] The long side plate portion 544b has an attachment portion 544f for detachably attaching to the power supply attachment member 540, which corresponds to the position of the power supply attachment member 540. The attachment portion 544f is configured by a protruding portion 544f protruding into the power supply cover 544. The protruding portion is also designated by the reference symbol "544f". As shown in FIG. 11(b), the protruding portion 544f engages with a recess in the standing plate portion 540b of the power supply attachment member 540. The recess here is an opening (through hole) 540g. The opening 540g is a through hole formed when the first support portion 540e is formed. This eliminates the need to provide a dedicated opening for attaching the power supply cover 544 to the power supply attachment member 540. As shown in FIG. 11B, the long side plate portion 544b has a holding portion 544g for holding the insulating rear case 547, which corresponds to the position of the cutout portion 547f of the insulating rear case 547. The holding portion 544g is formed by an extension piece 544g that extends from the long side plate portion 544b at an angle toward the rear side within the power supply cover 544. This allows the insulating rear case 547 to be supported (held) from the front side. The extension piece is also designated by the symbol "544g".

[0041] 11, a portion 544h of the long side plate portion 544b that is the front end and corresponds to the power supply mounting member 540 is a curved portion 544h that curves outward in the short side direction. The long side plate portion 544b is located outside the standing plate portion 540b of the power supply mounting member 540. This allows the power supply cover 544 to be easily attached to the base member 50 without the curved portion 544h of the long side plate portion 544b of the power supply cover 544 getting caught on the standing plate portion 540b of the power supply mounting member 540. The curved portion is also designated by the symbol "544h". 11, the long side plate portion 544b has a protruding piece 544j that protrudes at an angle toward the rear side within the power supply cover 544 at the front end portion corresponding to the power supply mounting member 540. The protruding piece 544j is located on the front side of the long side plate portion 547b of the insulating rear case 547. The base member 50 is connected to earth as shown in FIG. 12, and by attaching the power supply cover 544 to the power supply mounting member 540, the protruding piece 544j of the power supply cover 544 comes into contact with the power supply mounting member 540 attached to the base member 50, and is connected to earth.

[0042] As shown in Fig. 12, an end 544k of the long side plate 544b on the short side plate 544d side is a protruding portion 544k that protrudes in the longitudinal direction from the short side plate 544d. The reference symbol for this protruding portion is also "544k." The long side plate 544b is provided with a protruding portion 544f that engages with the power supply mounting member 540, and by expanding the protruding portion 544k in the short direction perpendicular to the long side plate 544b, the protruding portion 554f of the power supply cover 544 and the opening 540g of the power supply mounting member 540 are disengaged, and the power supply cover 544 can be removed from the power supply mounting member 540 without using tools or the like. 6 and 7, the long side plate portion 544b has an opening 544n through which a screwdriver or the like can be inserted at a portion thereof that does not face the power supply mounting member 540 and is close to the power supply mounting member 540. This makes it possible to insert a screwdriver from the opening 544n to expand the long side plate portion 544b of the power supply cover 544 in the short side direction of the device, and to remove the power supply cover 544 from the power supply mounting member 540.

[0043] 12, the short side plate portion 544d has an extension piece 544e that extends outward (outward in the longitudinal direction here) from the front end along the power supply board 542. The extension piece 544e is fixed by a screw 558 in contact with the power supply board 542 and is connected to earth. The extension piece 544e is connected to the base member 50 via a conductive plate 509. The conductive plate 509 is fixed to the base member 50 and the extension piece 544e by using the screws 558 and 559. As a result, the base member 50 is also connected to earth.

[0044] (7) Wearing equipment The following description will mainly use FIG. The mounting fixture 57 is formed by pressing a metal plate. As shown in Fig. 2, the mounting fixture 57 is provided at a position corresponding to the fixture-side mounting fixture 33 of the fixture 3, and there are two mounting fixtures 57 spaced apart in the longitudinal direction. This allows the lighting device 5 to be mounted to the fixture 3 in a stable state. As shown in FIG. 13, the mounting fixture 57 has a U-shaped portion 571 whose cross-sectional shape perpendicular to the longitudinal direction of the device is U-shaped with the front side open, and an opposing plate portion 572 which extends outward in the short direction of the device from the open side end of the U-shaped portion 571 and faces the flat portion 501 of the base member 50. The U-shaped portion 571 has an adjacent standing plate portion 573 from the inner ends of the pair of opposing plate portions 572 in the short side direction of the device, and a connecting plate portion 574 connecting the rear ends of the standing plate portions 573, and a "U"-shaped locking spring 331 which is the appliance-side mounting device 33 of the appliance 3 is engaged with the connecting plate portion 574. Note that the connecting plate portion 574 is provided with a bent piece 574a with which the locking spring 331 locks when the lighting device 5 is mounted on the appliance 3 (when the locking spring 331 is locked to the connecting plate portion 574), a groove 574b for positioning the locking spring 331, and the like.

[0045] 4B, the distance between the ends 572a of the opposing plate portion 572 in the short side direction of the device, i.e., the dimension of the mounting fixture 57 in the short side direction corresponds to the distance between the pair of rear L-shaped portions 507 of the base member 50. The ends 572a of the opposing plate portion 572 are inserted into the insertion groove portions 508 of the base member 50. The mounting fixture 57 has a recess (here, a through hole) 572b at a position corresponding to the position of the crimped portion of the rear extension portion 507a of the rear L-shaped portion 507 when the mounting fixture 57 is attached to the base member 50. This positions the mounting fixture 57 in the longitudinal direction of the device. In other words, the mounting fixture 57 is attached to the base member 50. In this manner, the mounting fixture 57 is attached to the base member 50 by crimping the insertion groove portion 508 (rear extension portion 507a) of the base member 50, without using screws. The through hole 572b has a rectangular shape when viewed from the back side, and has an arc-shaped portion 572c at the corner portion at the back side (outer side in the short direction) of the insertion groove portion 508. Even if a square punch is used to crimp the insertion groove portion 508 of the base member 50, the corner portion of the crimped portion is rounded because the back extension portion 507a has a certain thickness. By having the arc-shaped portion 572c, it becomes easier to fit with the rounded crimped portion, and the adhesion with the crimped portion can be improved. In addition, by increasing the adhesion, it is possible to prevent rattling and the like. In addition, the end portion 572a in the short direction of the facing plate portion 572 is an attachment portion that is inserted into the insertion groove portion 508 of the base member 50 and attached to the base member 50.

[0046] (8) Wireless communication unit As shown in FIG. 2, the wireless communication unit 58 is attached to the rear surface of the flat portion 501 of the base member 50 in the vicinity of the power supply unit 54. The wireless communication unit 58 houses a wireless module in a communication case 581 that receives a lighting signal from a controller not shown in the figure and outputs lighting conditions to the power supply circuit 543, and determines whether a received signal relates to the device itself when multiple lighting systems 1 are controlled by one controller.

[0047] Although the embodiment has been described above, the present invention is not limited to this embodiment, and may be modified as follows, for example. In addition, the embodiment and the modified examples may be combined, or the modified examples may be combined. Furthermore, examples not described in the embodiments and modifications, and design changes within the scope of the present invention are also included in the present invention.

[0048] <Modification> 1. Mounting recess The recesses in the embodiment are notches (portions) 540d and 532a when the mounting members are power supply mounting member 540 and end cover 53, and are through-holes 572b when the mounting member is attachment fixture 57. However, the recesses only need to be capable of receiving the crimped portion, and may be, for example, holes that do not pass through, or may be notches with a bottom such that the side opposite the crimped portion is blocked. The shape of the recess when viewed from the crimping direction may be square, rectangular, circular or elliptical. However, if it is desired to improve adhesion with the crimped portion, it is preferable to match the shape of the crimped portion.

[0049] 2. Mounting materials Although the mounting members 53, 57, and 540 integrally have a pair of mounting portions 532b, 572a, and 540c that are inserted into a pair of insertion grooves 508, the mounting members may have a structure having one mounting portion. However, when the mounting portions are integrally formed, rattling in the direction in which the insertion grooves 508 face each other (the short side direction of the device) can be reduced.

[0050] 3. Power supply mounting parts The power supply mounting member 540 has a pair of standing plate portions 540b to support the long edge side of the rectangular power supply board 542, but for example, at least two power supply mounting members may be arranged at both ends in the longitudinal direction of the power supply board 542, standing plate portions may be provided that stand along the short edge side of the power supply board, and a first support portion and a second support portion may be provided on the standing plate portions. In this case, two or more sets of the first support portion and the second support portion may be provided at an interval in the short direction. Although two power supply mounting members 540 are provided at a distance in the longitudinal direction, three may be provided in the longitudinal direction, or just one may be provided. In the case of one piece, for example, the power supply board may have a rectangular opposing plate portion that faces the base member and is long in the longitudinal direction of the power supply board, and at least two standing plate portions that stand upright from two edges corresponding to the long sides of the opposing plate portion, and each standing plate portion may be provided with a first support portion and a second support portion. Alternatively, the power supply board may have a rectangular opposing plate portion that faces the base member and is long in the longitudinal direction of the power supply board, and two standing plate portions that stand upright from both edges corresponding to the long sides of the opposing plate portion, and each standing plate portion may be provided with multiple sets of the first support portion and the second support portion. Alternatively, the power supply board may have a rectangular opposing plate portion that faces the base member and is long in the longitudinal direction of the power supply board, and two standing plate portions that stand upright from both edges corresponding to the short sides of the opposing plate portion, and each standing plate portion may be provided with one or multiple sets of the first support portion and the second support portion.

[0051] The recess of the power supply mounting member to which the mounting portion (projection portion) 544f of the power supply cover 544 is attached may be an opening 540g formed by a through hole as in the embodiment, or may be a recess formed by recessing a plate portion. The opening 540g, which is one example of a recess, utilizes a through hole for the first support portion 540e, but may be a recess formed separately from the first support portion. When the recess is provided in the end portion of the upright plate portion, for example, it may be formed by a notch portion that opens on the edge side.

[0052] 4. Power supply cover (1) Relationship with power supply mounting parts In the power supply cover 544 of the embodiment, the protruding portion (mounting portion) 544f that engages with the opening 540g, which is an example of a recess of the power supply mounting member 540, is provided on the long side plate portion 544b, but as explained in "3. Power Supply Mounting Member" above, for example, when the standing plate portion of the power supply mounting member is present on the side corresponding to the short side of the power supply board 542, the protruding portion (mounting portion) may be provided on the short side plate portion. In other words, in the present invention, the side plate portion on which the protruding portion (mounting portion) is provided may be the long side plate portion, the short side plate portion, or both side plate portions in relation to the standing plate portion of the power supply mounting member, and when the shape of the power supply cover when viewed from the back side is a circle, an ellipse, an oval, or further a polygon such as a pentagon, the side plate portion corresponds to the peripheral plate portion. In the power supply cover 544 of the embodiment, the curved portion 544h at the end on the flat portion side of the portion facing the power supply mounting member 540 is provided on the long side plate portion 544b, but as explained above in "3. Power supply mounting member", for example, when the standing plate portion of the power supply mounting member is present on the side corresponding to the short side of the power supply board 542, the curved portion may be provided on the end of the short side plate portion. In other words, in the present invention, the side plate portion on which the curved portion is provided may be the long side plate portion, the short side plate portion, or both side plate portions in relation to the standing plate portion of the power supply mounting member, and when the shape of the power supply cover when viewed from the back side is a circle, an ellipse, an oval, or even a polygon such as a pentagon, the side plate portion corresponds to the peripheral plate portion.

[0053] (2) Relationship with the insulating rear case In the embodiment, the long side plate portion 544b of the power supply cover 544 has a holding portion (extension piece) 544g for the insulating rear case 547, but the short side plate portions 544c and 544d may be provided with holding portions (extension pieces) and the short side plate portion 547c of the insulating rear case 547 may be provided with notches, or the long side plate portion 544b and the short side plate portions 544c and 544d may be provided with holding portions (extension pieces) and the short side plate portions 547b and 547c of the insulating rear case 547 may be provided with notches. In other words, the side plate portions of the power supply cover of the present invention may be a long side plate portion, a short side plate portion, or both side plate portions, and the side plate portions of the insulating rear cover of the present invention may be a long side plate portion, a short side plate portion, or both side plate portions. Furthermore, when the power supply cover and the insulating rear case have a circular, elliptical or oval shape when viewed from the rear, or a polygonal shape such as a pentagon, the side plate portion corresponds to the peripheral plate portion.

[0054] 5. Positioning member (holding member) (1) Positioning member In the embodiment, the positioning member also has a function of holding the conductive pin 552, but it does not have to have a holding function. In this case, the positioning member may be attached to the power supply board, the base member, or the insulating front case. Considering the number of parts, the installation work of the positioning parts, etc., it is preferable that the positioning member has a function of holding the conductive pin 552. In addition, a positioning member (holding member) having both a positioning function and a holding function, and one or more positioning members having only a positioning function may be provided. When a plurality of positioning members are provided, they are preferably provided at intervals in the longitudinal direction of the LED substrate.

[0055] (2) Convex part The first protrusions may position the LED substrate 511 slidable in the first direction (longitudinal direction), and the number of the first protrusions is not particularly limited, and may be, for example, one or three or more. The multiple first protrusions 554h may be provided in a line in the short-side direction of the LED substrate 511, or in multiple lines. In order to support the multiple first protrusions 554h so that they can be inserted into the through-holes 511a of the LED substrate 511, when using a protruding support portion 544j extending in the longitudinal direction of the LED substrate 511, a line in which the distance between the rotation center and the protrusions is constant is preferable. The second convex portion 554k may be omitted. However, considering the work of sinking the first convex portion 554h when the first convex portion 554h and the LED substrate 511 are close to each other, it is preferable to have the second convex portion 554k. There may be only one second convex portion 554k, but it is preferable that there are two second convex portions 554k on both sides of the first convex portion 554h (the first convex portion group when there are multiple second convex portions) in the direction in which the first convex portion 554h is arranged. This increases the efficiency of the work of sinking the first convex portion 554h when the first convex portion 554h and the LED substrate 511 are close to each other. [Explanation of symbols]
