[0010] Hereinafter, lighting devices and lighting fixtures according to embodiments of the present disclosure will be described in detail with reference to the drawings. However, the drawings described in the following embodiments are schematic diagrams, and the ratios of the sizes and thicknesses of the components do not necessarily reflect the actual dimensional ratios. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0011] (1) Overview An illumination device A1 (light source unit A1) according to this embodiment includes a light source module 1, a support member 3, and a power supply unit 2 (see FIGS. 1 to 3). The support member 3 supports the light source module 1. The power supply unit 2 supplies power to the light source module 1.

[0012] The light source module 1 includes a light source 10 and a conductive member 13 (see FIGS. 18 to 20). The conductive member 13 is electrically connected to the light source 10.

[0013] The support member 3 includes a support portion 30, an attachment portion 313, and a through-hole 316 (first through-hole 316). The support portion 30 has a first surface 30A and a second surface 30B opposite to the first surface 30A (see FIG. 20). The attachment portion 313 is used to attach the light source module 1 by sliding it in a predetermined direction (see FIG. 19). The first through-hole 316 penetrates the support portion 30 in the direction in which the first surface 30A and the second surface 30B are aligned (see FIG. 18).

[0014] The power supply unit 2 includes a receiving portion 26. The conductive member 13 that passes through the through hole 316 is inserted into the receiving portion 26 (see FIGS. 18 and 20).

[0015] The light source module 1 is attached to a first surface 30A of the support part 30. On the other hand, the power supply unit 2 is attached to a second surface 30B of the support part 30 (see FIG. 20).

[0016] By sliding the light source module 1 in a predetermined direction relative to the support member 3, the conductive member 13 and the receiving portion 26 are electrically connected (see FIGS. 18 and 19).

[0017] According to the lighting device A1 of this embodiment, when the light source module 1 is attached to the support member 3, the light source module 1 and the power supply unit 2 are electrically connected almost simultaneously. In this way, there is no need to separate the work of attaching the light source module 1 to the support member 3 from the work of electrically connecting the light source module 1 and the power supply unit 2.

[0018] Therefore, the ease of assembly can be improved.

[0019] (2) Details (2-1) Lighting equipment First, a lighting fixture B1 according to an embodiment (hereinafter abbreviated as lighting fixture B1) will be described.

[0020] As shown in FIGS. 1 to 3, the lighting fixture B1 includes a lighting device according to an embodiment, namely, a light source unit A1 (hereinafter abbreviated as light source unit A1), and a fixture body 6 that holds the light source unit A1. The light source unit A1 is detachably attached to the fixture body 6, which is directly attached to the ceiling. However, the fixture body 6 may also be embedded in the ceiling. Alternatively, the fixture body 6 may be directly attached to a wall or embedded in the wall.

[0021] The fixture main body 6 includes a long, box-shaped storage section 60 with an open bottom, a pair of reflecting plates 61 protruding obliquely upward from both longitudinal opening edges of the storage section 60, and a pair of end plates 62 provided on both longitudinal ends of the storage section 60 and the pair of reflecting plates 61 (see FIGS. 2 and 3). The storage section 60 and the pair of reflecting plates 61 are integrally formed by punching and bending a metal plate. However, the fixture main body 6 may not include the pair of reflecting plates 61 and may be configured only with the storage section 60 whose longitudinal ends are closed by the pair of end plates 62.

[0022] The fixture body 6 is installed on the ceiling S1 by inserting hanger bolts 90 into at least two of the multiple mounting holes 63 provided on the bottom surface (top surface) of the housing portion 60 and tightening nuts 91 onto the hanger bolts 90 (see FIG. 2). A power cable 92 is also inserted into one of the multiple power supply holes 64 provided on the bottom surface of the housing portion 60. However, when multiple lighting fixtures B1 are installed, another power cable for feeding wiring may be inserted into another power supply hole 64. Furthermore, another power cable for feeding wiring may be inserted into a hole formed by cutting out a knockout portion 620 (see FIG. 2) provided in the end plate 62.

[0023] A terminal block 65 is attached to the bottom surface of the housing portion 60. The terminal block 65 is electrically connected to a power line 93. A power connector 94 is provided at the tip of the power line 93.

[0024] Thus, the power cable 92 inserted into the power hole 64 of the fixture body 6 is electrically connected to the terminal block 65, and is electrically connected to the power supply unit 2 of the light source unit A1 via the terminal block 65, the power line 93 and the power connector 94.

[0025] The storage section 60 has a pair of hooking holes 600 (first hooked portions) and a pair of hooking fittings 601 (second hooked portions) at positions near both ends in the longitudinal direction (see FIGS. 2 and 5). The pair of hooking holes 600 are provided in a side wall at one end in the short direction of the storage section 60. The pair of hooking fittings 601 are located at the top of the other end in the short direction of the storage section 60 (see FIGS. 2 and 5). However, in the device body 6, instead of providing the pair of hooking holes 600 in a side wall at one end in the short direction of the storage section 60, fittings having hooking holes may be provided at one end in the short direction of the storage section 60.

[0026] (2-2) Light source unit 2 and 3, the light source unit A1 includes a light source module 1, a support member 3, a cover 5, a first hook member 37, and a second hook member 38. The light source unit A1 also includes a power supply unit 2 and a communication unit 4.

[0027] (2-2-1) Light source module The light source module 1 has two substrates 11 and a number of light sources 10 mounted on the surface (underside) of each substrate 11. The light sources 10 include, for example, LEDs (Light Emitting Diodes). The LEDs, which are light-emitting elements, are, for example, packaged white LEDs for lighting. However, the light-emitting elements are not limited to LEDs and may be organic electroluminescence elements, semiconductor laser elements, or the like.

[0028] Each substrate 11 is formed in a long rectangular shape. The multiple light sources 10 are mounted on the surface (lower surface) of each substrate 11 at the center of the short side direction, and are arranged in a row at equal intervals along the longitudinal direction of each substrate 11 (see FIG. 2). The multiple light sources 10 are electrically connected in series or series-parallel by printed wiring formed on the surface of each substrate 11. Furthermore, two sets of connectors 12 are mounted on one end of the surface of each substrate 11 in the longitudinal direction (see FIG. 2). The printed wiring formed on the surface of each substrate 11 is electrically connected via the two sets of connectors 12.

[0029] (2-2-2) Support member The support member 3 is made of a metal plate and is formed in the shape of a long rectangular trough (see Figs. 2 and 8). The support member 3 has a support portion 30, which is a long rectangular bottom plate, and a pair of side plates 31 that rise upward from both ends along the longitudinal direction of the support portion 30. The width of the support portion 30 in the short side direction is greater than the width of the substrate 11 in the short side direction (see Fig. 2).

[0030] The support part 30 also has protrusions 34 on both ends in the short side direction (see FIG. 8). Each protrusion 34 is U-shaped when viewed in the long side direction of the support part 30, and protrudes downward from the first surface 30A of the support part 30. The pair of side plates 31 protrude upward from the outer ends of the protrusions 34.

[0031] The support member 3 is provided with a pair of first hook members 37 protruding from one end in the short direction toward both ends in the longitudinal direction to the outside of the support member 3 (see FIGS. 2 and 3). Furthermore, the support member 3 is provided with a pair of second hook members 38 at the other end in the short direction toward both ends in the longitudinal direction (see FIG. 3). The pair of first hook members 37 and the pair of second hook members 38 play a role in holding the light source unit A1 to the fixture body 6.

[0032] The support member 3 supports the light source module 1, which will be described in detail in the section "(2-3) Mounting the light source module on the support member."

[0033] (2-2-3) First hook member The first hooking member 37 has a main piece 370 formed in the shape of a rectangular flat plate, a rising piece 371 bent upward from one longitudinal edge of the main piece 370, and a hooking piece 372 protruding from the tip (upper end) of the rising piece 371 in the opposite direction to the main piece 370 (see FIGS. 8 and 9). The tip of the hooking piece 372 is bent in a V-shape. The main piece 370, the rising piece 371, and the hooking piece 372 are integrally formed by bending a single metal plate.

[0034] The first hooking member 37 is attached to the support member 3 via a mounting bracket 39. The mounting bracket 39 has a first mounting portion 391, a second mounting portion 392, and a temporary holding portion 393 (see FIGS. 8 and 9).

[0035] The first mounting portion 391 has a rectangular first mounting plate 3910, a protruding plate 3911 rising from one short edge of the first mounting plate 3910, and four support pieces 3912 protruding upward from the other short edge of the first mounting plate 3910 (see FIGS. 8 and 9). An L-shaped support protrusion 3913 protrudes from each end of the tip of the protruding plate 3911 in the width direction.

[0036] Each of the four support pieces 3912 is formed in an L-shape. The four support pieces 3912 are arranged in two rows at intervals along the short-side and long-side directions of the first mounting plate 3910. However, two support pieces 3912 arranged along the long-side direction of the first mounting plate 3910 are arranged in a direction such that their tips approach each other.

[0037] The first hooking member 37 has the main piece 370 inserted into the space formed between the four support pieces 3912 and the first mounting plate 3910, and the hooking piece 372 inserted into the space formed between the tip of the projecting plate 3911 and the pair of support protrusions 3913. In other words, the first hooking member 37 is attached to the first mounting part 391 by the four support pieces 3912 and the pair of hooking pieces 372 so as to be slidable along the short-side direction of the first mounting plate 3910 (the short-side direction of the support part 30).

[0038] The second mounting portion 392 has a flat second mounting plate 3920 connected to one edge of the first mounting plate 3910 in the short direction, and a holding piece 3921 protruding upward from the second mounting plate 3920 (see FIG. 9). The holding piece 3921 is formed in an inverted U shape.

[0039] The temporary holding portion 393 is formed in a plate shape and protrudes upward from one end in the longitudinal direction (longitudinal direction of the support portion 30) of the second attachment plate 3920. The temporary holding portion 393 is formed integrally with the second attachment portion 392.

[0040] A recess 3930 is formed in the upper end portion of temporary holding portion 393. Recess 3930 is formed so that one wall extends in the vertical direction and the opposite wall slopes upward and away from the one wall (see FIG. 8). In addition, an L-shaped cutout is formed next to recess 3930 in the upper end portion of temporary holding portion 393.

[0041] The mounting bracket 39 is screwed to the second surface 30B (the surface (upper surface) opposite to the first surface 30A) of the support part 30 of the support member 3. However, the mounting bracket 39 may be fixed to the support part 30 by a method other than screwing, such as caulking, welding, or adhesive.

[0042] (2-2-4) Second hook member The second hooking member 38 has a coil portion 380 that corresponds to the fixed portion, and an arm portion 381 that protrudes from the coil portion 380 and hooks onto the appliance main body 6 (hooking metal fitting 601) (see FIG. 9). The arm portion 381 is formed by extending one of the two winding ends of the coil portion 380. In the following description, the other winding end of the coil portion 380 will be referred to as the winding end portion 382. The winding end portion 382 is formed to be sufficiently shorter than the arm portion 381 (see FIG. 9).

[0043] The arm 381 has a bent portion 383 that bends in the height direction (downward) toward the support member 3 (see FIG. 10). The bending angle of the bent portion 383 is an obtuse angle. The tip of the arm 381 is bent in an L-shape (see FIG. 9).

[0044] The second hooking member 38 is attached to the support member 3 via a mounting bracket 39. That is, the second hooking member 38 is attached to the second mounting portion 392 by hooking the coil portion 380 onto a holding piece 3921 of the second mounting portion 392 (see FIG. 9). When attached to the second mounting portion 392, the arm portion 381 is positioned so as to climb over the temporary holding portion 393.

[0045] The tip of winding end portion 382 is bent at a substantially right angle. Then, the tip of winding end portion 382 is inserted through groove 3922 provided in second mounting plate 3920 and into a groove provided in support portion 30. This restricts axial rotation of coil portion 380.

[0046] (2-2-5) Power supply unit The power supply unit 2 has a power supply device 20 and a power supply case 21 that houses the power supply device 20 (see FIG. 6).

[0047] Power supply device 20 has a printed circuit board 22 in which wiring conductors are printed on a rectangular insulating substrate, and a plurality of circuit components (not shown) mounted on both the front and back surfaces of printed circuit board 22. In other words, power supply device 20 is composed of a printed circuit.

[0048] 12 shows the circuit configuration of the power supply device 20. The power supply device 20 includes a power conversion circuit 200, a constant current circuit 201, a control circuit 202, and the like.

[0049] The power conversion circuit 200 includes, for example, a rectifier circuit such as a diode bridge, a boost chopper circuit (power factor correction circuit), etc. The power conversion circuit 200 converts AC power supplied from an external power source P1 through a power connector 23 into DC power. The external power source P1 is, for example, a commercial power system, and supplies AC voltage and current with an effective value of 100 V or 200 V. However, the power conversion circuit 200 may include a switching power supply circuit with a power factor correction function, such as a step-down chopper circuit, a step-up / step-down chopper circuit, or a flyback converter, instead of the step-up chopper circuit.

[0050] The constant current circuit 201 has, for example, a step-down chopper circuit (buck converter). The constant current circuit 201 steps down the DC voltage output from the power conversion circuit 200 and applies it to the light source module 1, and also adjusts the DC current flowing through the light source module 1. However, the constant current circuit 201 may include various chopper circuits, series regulators, etc. instead of the step-down chopper circuit.

[0051] The control circuit 202 includes, for example, a microcontroller. The control circuit 202 controls the power conversion circuit 200 so as to maintain the output voltage of the power conversion circuit 200 at a constant DC voltage. Furthermore, the control circuit 202 controls the step-down chopper circuit of the constant current circuit 201 so as to make the DC current supplied from the constant current circuit 201 to the light source module 1 coincide with a target value. The control circuit 202 changes the target value of the DC current supplied to the light source module 1 in response to a dimming signal received from the communication unit 4.

[0052] Here, the power connector 23 is mounted on one longitudinal end of the printed circuit board 22 (see FIG. 6). Note that the power connector 23 in the embodiment is a connector to which the power connector 94 is removably connected, but a terminal block to which the conductor of an electric wire is electrically connected may be used instead of the power connector 23. Alternatively, instead of the power connector 23, an output wire may be drawn out from the power supply device 20 and soldered to the conductor of the power line 93. Note that the configuration of the power connector 23 includes configurations other than those described above. However, in FIG. 6, illustration of circuit components mounted on the front surface (lower surface) and back surface (upper surface) of the printed circuit board 22 is omitted.

[0053] The power supply case 21 has a rectangular bottom wall 210 and a pair of first side walls 211 that protrude downward from both ends of the bottom wall 210 in the longitudinal direction along the short side of the bottom wall 210. The power supply case 21 also has a pair of second side walls 212 that protrude downward from both ends of the bottom wall 210 in the short side direction along the long side of the bottom wall 210 (see FIGS. 6 and 8). That is, the power supply case 21 is formed in the shape of a long box with an opening in the front (below) of the bottom wall 210. The socket for the power connector 23 protrudes to the outside of the power supply case 21 through a window hole provided in one of the first side walls 211 (see FIG. 8).

[0054] The power supply unit 2 is attached to the support part 30 of the support member 3 so that the opening of the power supply case 21 faces the second surface 30B of the support part 30 (see FIGS. 6 and 8). The power supply case 21 is attached to the support part 30 by an appropriate method such as screwing, crimping, or adhesive.

[0055] (2-2-6) Communication unit The communication unit 4 has a communication circuit section 40 and a communication connector 47 (see FIG. 12 ). The communication circuit section 40 receives control signals transmitted via a signal line (not shown). The control signals are signals that transmit control information such as a turn-on instruction, a turn-off instruction, and a dimming level. The communication circuit section 40 is communicably connected to the control circuit 202 of the power supply device 20 via the communication connector 47. The communication circuit section 40 transmits the control information contained in the received control signal to the control circuit 202 via the communication connector 47. The control circuit 202 turns the light source module 1 on and off, changes the dimming level, etc., in accordance with the control information received from the communication circuit section 40. However, the communication circuit section 40 may be configured to perform wireless communication using infrared or radio waves as a communication medium instead of wired communication.

[0056] The communication unit 4 also has a case 43 that houses the communication circuit section 40 and the communication connector 47 (see FIG. 6). The case 43 is formed in a box shape from electrically insulating synthetic resin. The case 43 is attached to the first side wall 211 of the power supply case 21 (the first side wall 211 opposite the power connector 23) (see FIG. 6). However, the communication unit 4 may be attached to a location other than the power supply case 21, for example, to the support member 3.

[0057] (2-2-7) Cover The cover 5 has a cover body 50 formed in the shape of a long semi-cylindrical cylinder, a pair of cover ends 54 attached to both ends of the cover body 50 in the longitudinal direction, a pair of protruding walls 51, and a pair of extending portions 53 (see FIGS. 2, 3, and 8). However, the shape of the cover body 50 is not limited to a long semi-cylindrical shape, and may be any shape such as a rectangular tube shape.

[0058] The pair of extending portions 53 extend inward from both ends of the cover body 50 in the shorter direction along the longitudinal direction of the cover body 50. The pair of projecting walls 51 extend upward along the longitudinal direction of the cover body 50 from connecting pieces 531 of the pair of extending portions 53 (see FIG. 8). Hook-shaped hook portions 52 are integrally formed on the upper ends of the pair of projecting walls 51 along the longitudinal direction of each projecting wall 51. The cover body 50, the pair of projecting walls 51, and the pair of hook portions 52 are integrally formed from a translucent synthetic resin such as acrylic resin or polycarbonate resin. However, the cover body 50, the pair of projecting walls 51, and the pair of extending portions 53 may be formed from a translucent material other than synthetic resin, for example, inorganic glass such as quartz glass.

[0059] The pair of cover ends 54 are formed in a semicircular shape in a plan view from the same translucent material as the cover body 50. The pair of cover ends 54 are attached, one to each end in the longitudinal direction of the cover body 50. In other words, both ends in the longitudinal direction of the cover body 50 are closed by the cover ends 54.

[0060] The cover 5 accommodates the support member 3 between a pair of protruding walls 51, and is attached to the support member 3 by hooking the hook portions 52 provided at the upper ends of the pair of protruding walls 51 onto the tips (upper ends) of the pair of side plates 31 of the support member 3 (see Figure 8).

[0061] The pair of extensions 53 are configured to cover at least a part of the portion of the first surface 30A of the support portion 30 of the support member 3 that is exposed to the outside of the light source module 1 (see FIG. 8).

[0062] Each extension portion 53 has a main piece 530, a connecting piece 531, and a side piece 532 (see FIG. 8). The connecting piece 531 is formed in a rectangular flat plate shape and protrudes inward from both ends of the cover body 50 in the short direction along the longitudinal direction of the cover body 50. The main piece 530 is formed in a V-shape when viewed in the longitudinal direction and protrudes inward from the tip of the connecting piece 531 along the longitudinal direction of the cover body 50. The side piece 532 is formed in a rectangular flat plate shape and protrudes upward from the tip of the main piece 530 along the longitudinal direction of the cover body 50. Note that the upper end of the side piece 532 comes into contact with the first surface 30A of the support portion 30 of the support member 3 when the cover 5 is attached to the support member 3 (see FIG. 8).

[0063] Here, the cover main body 50 and the cover end 54 are configured to diffuse light (illumination light) emitted from the light source module 1. Specifically, the cover main body 50 and the cover end 54 (or the entire cover 5) are formed of a synthetic resin with a light-diffusing filler, thereby imparting light diffusion properties to the cover main body 50 and the cover end 54. Most of the light emitted from the light source module 1 (light source 10) enters the cover main body 50 and the cover end 54 from their inner surfaces, is diffused by the filler, and then exits the cover 5 from at least a portion of the outer surfaces of the cover main body 50 and the cover end 54. However, some of the light emitted from the light source module 1 is reflected by the inner surfaces of the cover main body 50 and the cover end 54 and returns toward the support member 3. Some of the light reflected by the inner surfaces of the cover main body 50 and the cover end 54 is reflected by the surfaces (lower surfaces) of the extension portions 53 of the cover 5 and then passes through the cover main body 50 and the cover end 54. However, a part of the light emitted from the light source module 1 may be directly reflected by the surface (lower surface) of each extension portion 53.

[0064] Here, the extension portion 53 is preferably formed so that the reflectivity of its surface (lower surface) to visible light is higher than the reflectivity of the inner surface of the cover body 50 to visible light. For example, when the extension portion 53 and the cover body 50 are integrally formed by two-color molding, it is preferable that the type or amount of filler filled in the synthetic resin forming the extension portion 53 is different from the type or amount of filler filled in the synthetic resin forming the cover body 50. Alternatively, the surface (lower surface) of the extension portion 53 may be formed by two-layer two-color molding so that it has a higher reflectivity to visible light than the back surface (upper surface) of the extension portion 53. In other words, a first layer including the back surface (upper surface) of the extension portion 53 may be formed of a synthetic resin filled with the same type and amount of filler as the cover body 50, and a second layer including the surface (lower surface) of the extension portion 53 may be formed of a synthetic resin filled with a different type of filler than the cover body 50, or the same type but in a different amount. Alternatively, the reflectance for visible light may be increased by applying paint to the surface of the extension 53, which is made of the same synthetic resin as the cover body 50. Thus, by covering the protrusion 34 of the support member 3 with the extension 53 of the cover 5, the light source unit A1 can improve the efficiency (extraction efficiency) of extracting light emitted from the light source module 1 to the outside of the cover 5.

[0065] (2-3) Mounting the light source module to the support member The following describes the attachment of the light source module 1 to the support member 3. Hereinafter, the direction in which each of the light source module 1 and the support member 3 extends will be referred to as the "first direction D1 (front-rear direction)," the direction perpendicular to the first direction D1 and along the support member 30 will be referred to as the "second direction D2 (left-right direction)," and the direction perpendicular to both the first direction D1 and the second direction D2 will be referred to as the "third direction D3 (up-down direction)." The first direction D1, the second direction D2, and the third direction D3 do not need to be strictly perpendicular to each other, as long as this does not impair the effects of the present disclosure. The arrows indicating "D1," "D2," and "D3" in the drawings are not intended to define the directions of the light source unit A1 and the lighting fixture B1 during use, but are merely used to facilitate understanding of the description and are not substantial. In particular, the arrow indicating "D1" in the drawings has a "+" at one end and a "-" at the other end. "+" means "front" and "-" means "rear."

[0066] When the light source module 1 is attached to the support member 3, the light source module 1 and the power supply unit 2 are electrically connected almost simultaneously (see FIGS. 18 to 20). The respective configurations of the light source module 1, support member 3, and power supply unit 2 that achieve this will first be described, and then a specific attachment method will be described.

[0067] (2-3-1) Light source module As described above, the light source module 1 is elongated along the first direction D1 and includes the light source 10 and the substrate 11. In this manner, the first direction D1 is the longitudinal direction of the light source module 1. Note that the light source module 1 does not have to be elongated.

[0068] The substrate 11 has a mounting surface 11A, a non-mounting surface 11B, and through holes 18 (second through holes 18) (see FIGS. 18 and 20). The mounting surface 11A is the surface (bottom surface) on which the light source 10 is mounted. The non-mounting surface 11B is the surface (top surface) opposite the mounting surface 11A and is a substantially flat surface. The second through holes 18 penetrate the substrate 11 in the direction in which the mounting surface 11A and the non-mounting surface 11B are aligned. The second through holes 18 are elongated holes that are long in the first direction D1.

[0069] The light source module 1 further includes a conductive member 13. The conductive member 13 is electrically connected to the light source 10. Specifically, the conductive member 13 includes a blade terminal 16, a board-side terminal 131, and an exterior body 130 (see FIG. 22).

[0070] The blade terminals 16 protrude from the mounting surface 11A toward the non-mounting surface 11B in the third direction D3. The cutting edges of the blade terminals 16 face forward in the first direction D1. In the following description, the forward direction in the first direction D1 is referred to as the "predetermined direction," and the rearward direction in the first direction D1 is referred to as the "opposite direction to the predetermined direction." In this manner, the predetermined direction and the opposite direction to the predetermined direction are both directions included in the first direction D1.

[0071] The board-side terminals 131 are mechanically and electrically connected to the board 11 while almost completely blocking the second through-holes 18 from the mounting surface 11A side. In Fig. 18, the conductive members 13 are shown separated from the board 11, but in reality, the conductive members 13 are integrated with the board 11 as shown in Fig. 22. Furthermore, the board-side terminals 131 are electrically connected to the light source 10.

[0072] The exterior body 130 (insulator) is an insulating resin component. Inside the exterior body 130, the blade terminals 16 and the board-side terminals 131 are electrically connected.

[0073] Furthermore, the light source module 1 has a recess 14. Specifically, the substrate 11 has the recess 14. In the substrate 11, the recess 14 is open on both sides in the second direction D2. A plurality of recesses 14 are provided on each side of the substrate 11 in the second direction D2, but this is not limiting.

[0074] (2-3-2) Support member As described above, the support member 3 supports the light source module 1 and is elongated along the first direction D1. In this manner, the first direction D1 is also the longitudinal direction of the support member 3. Note that the support member 3 does not have to be elongated.

[0075] The support member 3 includes a support portion 30, an attachment portion 313, and a through hole 316 (first through hole 316).

[0076] The support portion 30 has a first surface 30A and a second surface 30B. The first surface 30A is a substantially flat surface that faces the non-mounting surface 11B of the substrate 11. The second surface 30B is the surface opposite to the first surface 30A.

[0077] The mounting portion 313 is used to mount the light source module 1 by sliding it in a predetermined direction (forward in the first direction D1). The mounting portion 313 corresponds to the recess 14 of the substrate 11.

[0078] The mounting portion 313 is substantially L-shaped. Specifically, the mounting portion 313 has a base 314 and a protruding portion 315. The base 314 protrudes from the first surface 30A in a normal direction (third direction D3) of the first surface 30A. In other words, the base 314 protrudes downward from the first surface 30A. The protruding portion 315 protrudes from the tip of the base 314 in a direction opposite to the predetermined direction (rearward in the first direction D1). The length of the protruding portion 315 in the first direction D1 is equal to or less than the length of the recess 14 in the first direction D1. This makes it less likely that the mounting portion 313 will interfere with the substrate 11 when the non-mounting surface 11B of the substrate 11 is placed on the first surface 30A of the support 30.

[0079] It is desirable that the attachment portion 313 be located near the connection structure (secondary-side wireless structure) between the conductive member 13 and the receiving portion 26. In this way, by having the attachment portion 313 located near the secondary-side wireless structure, deformation of the secondary-side wireless structure can be suppressed even if the light source unit A1 vibrates or if the light source unit A1 is dropped in its packaged state and receives an impact. Furthermore, by having the attachment portion 313 located near the secondary-side wireless structure, it is possible to accurately position the secondary-side wireless structure.

[0080] The first through hole 316 penetrates the support part 30 in the direction in which the first surface 30A and the second surface 30B are aligned. Like the second through hole 18 of the substrate 11, the first through hole 316 is also an elongated hole that is long in the first direction D1. From the start to the end of attachment of the light source module 1 to the support member 3, the positions of the first through hole 316 and the second through hole 18 are shifted along the first direction D1, but the first through hole 316 and the second through hole 18 continue to communicate with each other.

[0081] The support member 3 further includes a restricting portion 33 (see FIG. 21 ). The restricting portion 33 restricts movement of the light source module 1. More specifically, the restricting portion 33 restricts movement of the light source module 1 after the light source module 1 is attached to the support member 3. Specifically, after the light source module 1 is attached to the support member 3, the restricting portion 33 is cut and raised from the support portion 30 and hooked onto the inner surface of the recess 14 of the substrate 11.

[0082] (2-3-3) Power supply unit As described above, the power supply unit 2 supplies power to the light source module 1. The power supply unit 2 includes a receiving portion .

[0083] The receiving portion 26 is provided on the surface (lower surface) of the printed circuit board 22. The conductive member 13 is inserted into the receiving portion 26. More specifically, the conductive member 13 passes through the first through-hole 316 of the support member 3 and is inserted into the receiving portion 26.

[0084] Specifically, the receiving portion 26 has a recess 261. The recess 261 is recessed in the third direction D3 (upward) and in a predetermined direction (forward in the first direction D1). The blade terminal 16 is inserted into the recess 261.

[0085] (2-3-4) Installation method The light source module 1 is attached to the support member 3 as follows.

[0086] First, the light source module 1 is placed on the support member 3. Specifically, the non-mounting surface 11B of the substrate 11 is placed on the first surface 30A of the support portion 30. At this time, the attachment portion 313 passes through the recess 14 along the third direction D3 and does not interfere with the substrate 11.

[0087] Meanwhile, the power supply unit 2 is attached to the second surface 30B of the support part 30. The receiving part 26 is arranged at a position overlapping with the first through-hole 316 in the third direction D3. At this time, the conductive member 13 is located at a position away from the receiving part 26 in a direction opposite to the predetermined direction (rearward in the first direction D1). Note that the distance between the conductive member 13 and the receiving part 26 in the first direction D1 at this time is approximately equal to the moving distance when the light source module 1 is slid in the predetermined direction (forward in the first direction D1), as described below.

[0088] Next, the light source module 1 is slid in a predetermined direction (forward in the first direction D1) relative to the support member 3. As a result, a portion 15 of the light source module 1 (specifically, a corner 15a continuing into the recess 14) is inserted between the first surface 30A of the support part 30 and the protrusion 315. As a result, the light source module 1 is attached to the first surface 30A of the support part 30. In this manner, with the light source module 1 attached to the support member 3, the portion 15 of the light source module 1 is sandwiched between the first surface 30A and the protrusion 315 (see FIG. 19 ). Note that when the portion (corner 15a) of the light source module 1 hits the base 314 of the attachment part 313, the light source module 1 cannot be slid any further, and this serves as an indication that the attachment work is complete.

[0089] Meanwhile, by sliding the light source module 1 in a predetermined direction (forward in the first direction D1) relative to the support member 3, the conductive member 13 and the receiving portion 26 are electrically connected. That is, the blade terminals 16 protruding in the third direction D3 are inserted into the recesses 261 of the receiving portion 26 in the predetermined direction (forward in the first direction D1). Thereafter, by forming the restricting portions 33 by cutting and raising them from the support member 30, it is possible to prevent the substrate 11 from shifting in the direction opposite to the predetermined direction (rearward in the first direction D1).

[0090] (2-4) Installation of lighting fixtures The lighting fixture B1 is installed on the ceiling of the room in the following procedure.

[0091] First, the installation worker pulls the power cable 92, which has been pulled out from the ceiling S1, into the housing 60 through the power supply hole 64 at the center of the fixture body 6 (see FIG. 2). The worker also pulls the signal line 96, which has been pulled out from the ceiling S1, into the housing 60 through the power supply hole 64 at the longitudinal end of the fixture body 6 (see FIG. 2). After that, the worker inserts two suspension bolts 90 provided in the ceiling S1 into a pair of mounting holes 63 in the fixture body 6, and attaches the fixture body 6 to the ceiling S1 by tightening nuts 91 via washers (not shown) onto the suspension bolts 90 inserted into each mounting hole 63. Then, the worker electrically connects the power cable 92, which has been pulled out from the central power supply hole 64, to the terminal block 65.

[0092] Next, as a preparatory step for attaching the light source unit A1 to the fixture body 6, the worker fits the arm portions 381 of each of the two second hooking members 38 into the recesses 3930 of the temporary holding portion 393 of the mounting bracket 39 (see FIG. 13 ). At this time, the inner wall of the recess 3930 in the temporary holding portion 393 is inclined toward the recess 3930, so the arm portions 381 can be guided toward the recess 3930. Therefore, the light source unit A1 can improve the workability of the work of holding the arm portions 381 in the temporary holding portion 393. However, the arm portions 381 of each of the two second hooking members 38 may be fitted into the recesses 3930 of the temporary holding portion 393 of the mounting bracket 39 at the time of shipment. In this case, the above preparatory step by the worker can be omitted, thereby reducing the worker's workload and improving workability.

[0093] By holding the arm portion 381 in the temporary holding portion 393, the space in the height direction between the upper end of the wall portion (the side plate 31 of the support member 3 and the protruding wall 51 of the cover 5) of the light source unit A1 and the arm portion 381 increases (see height H1 in FIG. 10 and height H2 in FIG. 11). Furthermore, the worker slides the hook piece 372 of the first hook member 37 to a position where the rising piece 371 abuts against the protruding plate 3911 of the mounting bracket 39 (see FIG. 13).

[0094] Then, the worker inserts the hooking pieces 372 of the pair of first hooking members 37 of the light source unit A1 into the pair of hooking holes 600 of the fixture body 6 and hooks the tip portion of each hooking piece 372 onto the edge of each hooking hole 600 in the side wall of the accommodating section 60, thereby temporarily hanging the light source unit A1 on the fixture body 6 (see FIG. 14 ). In this temporarily hanging state, the worker electrically connects the power connector 94 at the tip of the power line 93 connected to the terminal block 65 to the power connector 23 of the power supply unit 2, and electrically connects the signal line 96 to the communication unit 4.

[0095] Next, the worker inserts his or her fingers into the space between the arm portion 381 of the second hooking member 38 and the protruding wall 51, pushes up the arm portion 381 with the fingers, and hooks the tips of the arm portion 381 onto the two hooking fittings 601 of the fixture main body 6, one by one (see FIG. 15 ). Then, the worker lifts the light source unit A1 while rotating it in the short direction, using the hook piece 372 that is abutting on the edge of the hooking hole 600 as a fulcrum. Then, the deformed second hooking member 38 returns to its original state, and the light source unit A1 is held in the fixture main body 6 with the power supply unit 2 and the communication unit 4 accommodated in the accommodation section 60 by the first hooking member 37 hooked onto the edge of the hooking hole 600 and the second hooking member 38 hooked onto the hooking fitting 601 (see FIGS. 1 and 8 ).

[0096] The lighting fixture B1 is installed on the ceiling using the above procedure.

[0097] Here, when lighting fixture B1 is installed on the ceiling, the two hanging bolts 90, nuts 91, and washers (not shown) are all located between the power supply unit 2 and the communication unit 4 of light source unit A1 in the longitudinal direction of fixture body 6 (see FIGS. 6 and 7). In other words, lighting fixture B1 has the advantage that the height dimension can be shortened (thinner thickness) because the two hanging bolts 90, nuts 91, and washers (not shown) do not overlap with the power supply unit 2 and the communication unit 4 in the vertical direction.

[0098] Furthermore, in the fixture body 6, the two hooking fittings 601 are disposed near the mounting hole 63. This shortens the distance between the position where the tightening force of the nut 91 is applied to the fixture body 6 (around the mounting hole 63 of the accommodation section 60) and the position where the spring force of the second hooking member 38 is applied to the fixture body 6 (the position of the hooking fittings 601). As a result, the lighting fixture B1 can suppress bending of the fixture body 6 along the longitudinal direction, and can reduce the gap between the fixture body 6 and (the cover 5 of) the light source unit A1.

[0099] Furthermore, multiple lighting fixtures B1 may be installed on the ceiling S1 in a row with the end plates 62 of their respective fixture bodies 6 butted against each other. In this case, power cables 95 are routed between adjacent lighting fixtures B1 through holes formed by cutting out the knockout portions 620 of the end plates 62. That is, two power cables 95 are electrically connected to the terminal block 65 of one lighting fixture B1 (see FIG. 16). In this case, each power cable 95 is held by a cable holding portion 602 cut and raised from the bottom surface (lower surface) of the housing portion 60 (see FIG. 16). However, the housing portion 60 does not necessarily have to have the cable holding portion 602. Here, the light source unit A1 has the power supply unit 2 disposed near one end of the support member 3 in the short direction (see FIG. 8). As a result, the light source unit A1 and the lighting fixture B1 have sufficient space to accommodate the power line 93 connecting the terminal block 65 and the power supply unit 2, and the power cable 95 for the feed wiring, thereby improving the workability of the wiring work.

[0100] (2-5) Advantages of the embodiment According to the lighting device A1 of the embodiment, as shown in FIGS. 18 to 20, when the light source module 1 is attached to the support member 3, the light source module 1 and the power supply unit 2 are electrically connected almost simultaneously. In the lighting device of Patent Document 1, the process of attaching the LED board to the base member and the process of connecting the conductive pins to the LED board and the power supply board are separate. However, in the lighting device A1 of the embodiment, there is no need to separate the process of attaching the light source module 1 to the support member 3 from the process of electrically connecting the light source module 1 and the power supply unit 2. This improves ease of assembly.

[0101] In the lighting device A1 according to this embodiment, the light source module 1 and the support member 3 are each elongated along a direction including a predetermined direction (forward in the first direction D1). This allows the number of attachment portions 313 to be increased along the longitudinal direction. As a result, the support member 3 can easily hold the light source module 1.

[0102] 18 (corner 15a continuing to recess 14) is sandwiched between first surface 30A and protrusion 315 (see FIG. 19) when light source module 1 is attached to support member 3. This makes it even easier for support member 3 to hold light source module 1.

[0103] Furthermore, in the lighting device A1 according to the embodiment, the support member 3 includes the restricting portion 33, which can prevent the light source module 1 from coming off. That is, even if a force acts on the light source module 1 in the opposite direction to that applied when the light source module 1 is attached to the support member 3 after the light source module 1 is attached to the support member 3, the restricting portion 33 can prevent the light source module 1 from sliding due to the force.

[0104] Furthermore, in the lighting device A1 according to this embodiment, the conductive member 13 includes blade terminals 16. Therefore, even if the light source module 1 thermally expands in the longitudinal direction, the thermal expansion displacement can be absorbed as long as the displacement is equal to or less than the longitudinal length of the blade terminals 16. In this respect alone, the blade terminals 16 are more effective than the pin terminals 17.

[0105] Furthermore, in the lighting device A1 according to the embodiment, the conductive member 13 includes a pin terminal 17. While blade terminals 16 require the blades to be aligned in the first direction D1, pin terminals 17 do not require this and only require the blades to be aligned in the third direction D3. In this respect alone, the pin terminals 17 are more effective than the blade terminals 16.

[0106] Furthermore, in the lighting device A1 according to the embodiment, it is desirable that the through-hole 316 (first through-hole 316) of the support member 3 is blocked when the light source module 1 is attached to the support member 3. This can prevent insects or foreign objects from entering the inside of the cover 5 through the through-hole 316.

[0107] Furthermore, according to the lighting fixture B1 of this embodiment, the first hooking member 37 is hooked onto the first hooked portion, thereby improving the workability of attaching the lighting device A1 to the fixture body 6.

[0108] (3) Modifications of the embodiment Next, several modified examples of the light source unit A1 and lighting fixture B1 according to the embodiment will be described. However, the basic configuration of the light source unit A1 and lighting fixture B1 of each modified example described below is the same as the basic configuration of the light source unit A1 and lighting fixture B1 according to the embodiment. Therefore, the same reference numerals will be used to designate components that are common or substantially common to the basic configuration of the light source unit A1 and lighting fixture B1 according to the embodiment, and illustrations and descriptions thereof will be omitted as appropriate. Note that "substantially common configuration" means a configuration that is slightly different in shape, size, etc., but has the same function. Furthermore, each modified example described below can be appropriately combined with the embodiment and other modified examples.

[0109] (3-1) Variation 1 As shown in FIG. 23, the conductive member 13 of the first modification is a connector type (plug). In the conductive member 13 of the first modification, the contacts 132 are held by an exterior body 130 (insulator). The contacts 132 extend upward from the board-side terminals 131, then change direction and extend forward. One end of the contacts 132 is exposed to the outside in a predetermined direction (forward in the first direction D1). The other end of the contacts 132 is electrically connected to the light source 10. The conductive member 13 of the first modification is connectable to a receiving portion 26 along the first direction D1. The conductive member 13 of the first modification is connectable to, for example, a receiving portion 26 shown in FIG. 37, which will be described later. The connector shape is not particularly limited.

[0110] (3-2) Variation 2 24, the conductive member 13 of the second modification does not include an exterior body 130. The blade terminals 16 and the board-side terminals 131 are integrated together. The board-side terminals 131 are connected to the board 11 by soldering.

[0111] (3-3) Variation 3 As shown in FIG. 25, in the conductive member 13 of the third modification, the cutting edge portion of the blade terminal 16 is formed in a thick plate shape.

[0112] (3-4) Variation 4 26, the conductive member 13 of the fourth modification is a conductor plate 133 that is generally S-shaped in side view. One end of the conductor plate 133 protrudes in a predetermined direction (forward in the first direction D1). The other end of the conductor plate 133 protrudes in a direction opposite to the predetermined direction (rearward in the first direction D1) and is mechanically and electrically connected to the substrate 11. The conductor plate 133 is electrically connected to the light source 10.

[0113] (3-5) Variation 5 27 , the conductive member 13 of the fifth modification includes a pin terminal 17. The pin terminal 17 extends in the third direction D3 and is disposed so as to pass through the second through-hole 18 of the substrate 11. One end of the pin terminal 17 is inserted into the receiving portion 26. The other end of the pin terminal 17 is connected to the substrate 11 by soldering.

[0114] (3-6) Variation 6 28, the conductive member 13 of the sixth modification is placed on the non-mounting surface 11B of the substrate 11. That is, the substrate 11 does not have the second through-hole 18.

[0115] Here, printed wiring is formed on the mounting surface 11A and the non-mounting surface 11B of the substrate 11. In other words, the substrate 11 is a double-sided substrate. Therefore, it is necessary to ensure insulation between the substrate 11 and the support member 3. For example, insulation between the substrate 11 and the support member 3 can be ensured by ensuring an insulating distance between the substrate 11 and the support member 3 or by interposing insulating tape or the like.

[0116] If printed wiring is formed only on mounting surface 11A on which light source 10 is mounted, i.e., if printed wiring is not formed on non-mounting surface 11B, substrate 11 is a single-sided substrate. In this case, there is no need to ensure insulation between substrate 11 and support member 3, which is advantageous in terms of cost.

[0117] (3-7) Variation 7 29, the conductive member 13 of the seventh modification is fixed to the substrate 11 by snap fitting. Claws 134 are provided on the outer periphery of the exterior body 130. The claws 134 are caught on the inner periphery of the second through-holes 18, thereby fixing the conductive member 13 to the substrate 11. In this way, with snap fitting, the conductive member 13 can be attached to the substrate 11 with a single touch.

[0118] (3-8) Variation 8 30 and 31, the receiving portion 26 of the eighth modification has a recess 261 that is substantially U-shaped when viewed from the front. A part of the socket contact 263 is exposed from the inner surface of the recess 261.

[0119] The distance in the second direction D2 of the recess 261 may be the same between the entrance and the exit. The entrance is located on one end side (negative side) of the recess 261 in the first direction D1. The exit is located on the other end side (positive side) of the recess 261 in the first direction D1.

[0120] Alternatively, the entrance may be wide and the exit may be narrow, which makes it easier to insert the blade terminals 16 or pin terminals 17 by sliding them from the entrance side to the exit side of the recess 261 along the first direction D1. Furthermore, when the blade terminals 16 or pin terminals 17 are inserted all the way in (near the exit side), it becomes easier to ensure a reliable electrical connection between the conductive member 13 and the receiving portion 26.

[0121] (3-9) Variation 9 The receiving portion 26 of Modification 9 differs from the receiving portion 26 of Modification 8 in the orientation of the recess 261. That is, as shown in Figures 32 and 33, the receiving portion 26 of Modification 9 has a recess 261 that is approximately U-shaped in plan view. A portion of the socket contact 263 is exposed from the inner surface of the recess 261.

[0122] (3-10) Variation 10 As shown in FIGS. 34 and 35 , the receiving portion 26 of the tenth modification is configured with a pair of conductive plates 221. The printed circuit board 22 has a through hole 220. The through hole 220 penetrates the printed circuit board 22 in the direction in which the front surface (lower surface) and the back surface (upper surface) of the printed circuit board 22 are aligned. The pair of conductive plates 221 face each other on the back surface (upper surface) of the printed circuit board 22, sandwiching the through hole 220 therebetween. The pair of conductive plates 221 are mountain-shaped in a front view. That is, the tips of the pair of conductive plates 221 become closer as they move away from the through hole 220. The tips of the pair of conductive plates 221 can elastically contact the conductive member 13.

[0123] As in the case of Modification 8, the distance in the second direction D2 of the recess 261 may be the same between the entrance and the exit. The entrance is located on one end side (negative side) of the recess 261 in the first direction D1. The exit is located on the other end side (positive side) of the recess 261 in the first direction D1.

[0124] Alternatively, the entrance may be wide and the exit may be narrow, which makes it easier to insert the blade terminals 16 or pin terminals 17 by sliding them from the entrance side to the exit side of the recess 261 along the first direction D1. Furthermore, when the blade terminals 16 or pin terminals 17 are inserted all the way in (near the exit side), it becomes easier to ensure a reliable electrical connection between the conductive member 13 and the receiving portion 26.

[0125] (3-11) Variation 11 As shown in FIG. 36, the receiving portion 26 of the 11th modification does not include an exterior body 262 (see FIG. 37). The socket contacts 263 are exposed and solder-connected to the substrate 11. The socket contacts 263 have a pair of conductor pieces 264 extending downward. The tips of the pair of conductor pieces 264 are bent in a substantially V-shape so as to face each other. The space between the tips of the pair of conductor pieces 264 forms a recess 261.

[0126] As in the case of Modification 8, the distance in the second direction D2 of the recess 261 may be the same between the entrance and the exit. The entrance is located on one end side (negative side) of the recess 261 in the first direction D1. The exit is located on the other end side (positive side) of the recess 261 in the first direction D1.

[0127] Alternatively, the entrance may be wide and the exit may be narrow, which makes it easier to insert the blade terminals 16 or pin terminals 17 by sliding them from the entrance side to the exit side of the recess 261 along the first direction D1. Furthermore, when the blade terminals 16 or pin terminals 17 are inserted all the way in (near the exit side), it becomes easier to ensure a reliable electrical connection between the conductive member 13 and the receiving portion 26.

[0128] (3-12) Variation 12 As shown in FIG. 37, the receiving portion 26 of the 12th modification is a connector type (receptacle). In the receiving portion 26 of the 12th modification, a socket contact 263 is held by an exterior body 262 (insulator). The socket contact 263 has a pair of conductor pieces 264. The pair of conductor pieces 264 extend in a direction opposite to the predetermined direction (rearward in the first direction D1). The tips of the pair of conductor pieces 264 are bent in a substantially V-shape so as to face each other. A recess 261 is formed between the tips of the pair of conductor pieces 264. The receiving portion 26 of the 12th modification can be connected to the conductive member 13 of the 1st modification shown in FIG. 23 along the first direction D1, for example. The shape of the connector is not particularly limited.

[0129] (3-13) Variation 13 The support unit 30 of Modification 13 differs from the support unit 30 of the embodiment of the present disclosure in the structure of the mounting portion 313. That is, in the support unit 30 of Modification 13, as shown in FIG. 38 , mounting portions 313 are provided on both sides of the support unit 30 in the second direction D2. The base portions 314 of the mounting portions 313 provided on one side (left side) in the second direction D2 protrude downward from both sides of the support unit 30 in the second direction D2, and the protrusions 315 protrude to the other side (right side) in the second direction D2. On the other hand, the base portions 314 of the mounting portions 313 provided on the other side (right side) in the second direction D2 protrude downward from both sides of the support unit 30 in the second direction D2, and the protrusions 315 protrude to one side (left side) in the second direction D2. In this way, the support unit 30 can hold the light source module 1 by holding the substrate 11 of the light source module 1 from both sides with the pair of left and right mounting portions 313.

[0130] (3-14) Variation 14 39 , the support part 30 of the modification 14 differs from the support part 30 of the modification 13 in that one of the pair of attachment parts 313 does not have the protrusion 315. When attaching the board 11 of the light source module 1 to the support part 30 of the modification 14, first, the left end part of the board 11 is hooked onto the attachment part 313 on the left side of the support part 30, and then the right end part of the board 11 is pushed up. In this manner, the board 11 can be attached to the support part 30.

[0131] (3-15) Variation 15 40, the support part 30 of the modification 15 differs from the support part 30 of the modification 13 in that the attachment parts 313 are provided intermittently along the first direction D1. In this way, when the attachment parts 313 are provided intermittently, the substrate 11 can be inserted and slid not only from one end of the support part 30 in the first direction D1, but also from the middle of the support part 30 in the first direction D1.

[0132] (3-16) Variation 16 Modification 16 is an example of how the power supply case 21 is attached to the support part 30. In the power supply case 21 of modification 16, as shown in FIG. 41 , a plurality of L-shaped claws 222 are provided at the bottom end of the second side wall 212. The support part 30 has through holes (not shown) at positions corresponding to the claws 222 of the power supply case 21. The power supply case 21 can be attached to the support part 30 by inserting and sliding the claws 222 into these through holes. Note that the claws 222 may also be provided on the first side wall 211.

[0133] In the embodiment of the present disclosure, the conductive member 13 and the receiving portion 26 are electrically connected by sliding the light source module 1 in a predetermined direction relative to the support member 3, but it is also possible to fix the light source module 1 to the support member 3 and slide the power supply case 21 relative to the support member 3 to electrically connect the conductive member 13 and the receiving portion 26.

[0134] (3-17) Variation 17 The power supply case 21 of Modification 17 differs from the power supply case 21 of Modification 16 in the shape and position of the claws 223. That is, in the power supply case 21 of Modification 17, as shown in Fig. 42, a plurality of claws 223 bent into an L-shaped plate are provided on the lower end of the first side wall 211. Note that the claws 223 may also be provided on the second side wall 212.

[0135] In variant 17, as in variant 16, the light source module 1 may be fixed to the support member 3, and the power supply case 21 may be slid relative to the support member 3 to electrically connect the conductive member 13 and the receiving portion 26.

[0136] (3-18) Variation 18 Variation 18 is yet another example of how the power supply case 21 is attached to the support part 30. In the power supply case 21 of variation 18, as shown in FIG. 43 , a flange part 224 is provided at the lower end of the second side wall 212. A through hole 225 is provided in the flange part 224. Meanwhile, an L-shaped claw 302 is provided on the second surface 30B of the support part 30. The power supply case 21 can be attached to the support part 30 by inserting and sliding this claw 302 into the through hole 225.

[0137] In variant 18, as in variant 16, the light source module 1 may be fixed to the support member 3, and the power supply case 21 may be slid relative to the support member 3 to electrically connect the conductive member 13 and the receiving portion 26.

[0138] (3-19) Variation 19 44, in the light source module 1 of Modification 19, a large number of light sources 10 are mounted on a substrate 11 in two rows along a first direction D1. The second through holes 18 are provided between the two rows of light sources 10 in the second direction D2.

[0139] The light sources 10 do not have to be arranged in two rows. The light sources 10 may be arranged in one row, or three or more rows. Furthermore, the substrate 11 does not have to be long.

[0140] (3-20) Variation 20 In the light source module 1 of the modified example 20, as shown in FIG. 45, the second through-hole 18 is provided at a position close to the end of the substrate 11 in the first direction D1.

[0141] (3-21) Variation 21 46, in the light source module 1 of the modification 21, the second through hole 18 is open not only in the third direction D3 but also on one side in the second direction D2. That is, the second through hole 18 is formed by cutting out one end of the substrate 11 in the second direction D2 in a rectangular shape.

[0142] (3-22) Variation 22 In the light source module 1 of the modified example 22, as shown in FIG. 47, the second through-holes 18 are provided at positions (for example, at the center) away from both ends of the substrate 11 in the first direction D1.

[0143] (3-23) Variation 23 In the light source module 1 of the twenty-third modification, as shown in FIG. 48, the second through-hole 18 is provided at a position closer to the end of the substrate 11 in the first direction D1 than in the light source module 1 of the twenty-third modification.

[0144] (3-24) Variation 24 49, on the surface (lower surface) of the printed circuit board 22, the receiving portion 26 is disposed on the secondary side, but may be disposed on the primary side or between the primary and secondary sides. Note that the primary side refers to the side to which AC power is supplied from an external power source, and the secondary side refers to the side to which DC power is supplied to the light source module 1.

[0145] (3-25) Variation 25 50, in the twenty-fifth modification, the power connector 23 is provided on the outside of the power supply case 21. Specifically, the power connector 23 is provided on the first side wall 211 of the power supply case 21.

[0146] The power supply case 21 houses multiple circuit components (not shown). Depending on the size of the circuit components, there is a risk that the circuit components inside the power supply case 21 may interfere with the conductive member 13 when the light source module 1 is slid to electrically connect the conductive member 13 to the receiving portion 26. Therefore, in Modification 25, the power connector 23 is provided on the outside of the power supply case 21. This makes it possible to suppress interference between the conductive member 13 and the circuit components inside the power supply case 21. Furthermore, the layout of the multiple circuit components inside the power supply case 21 is relatively free.

[0147] (3-26) Other variations In the embodiment of the present disclosure, the number of poles of the conductive member 13 and the receiving portion 26 is two, but is not limited to this number. For example, the number of poles of the conductive member 13 and the receiving portion 26 may be three. The three poles are, for example, the positive (+), negative (-), and ground of the power supply.

[0148] In the embodiment of the present disclosure, the support member 3 has only one through hole 316 (first through hole 316), but the support member 3 may have multiple through holes 316. That is, the support member 3 may have one or multiple through holes 316 depending on the number of poles of the conductive member 13 and the receiving portion 26.

[0149] In the embodiment of the present disclosure, the substrate 11 has the recess 14, but may have a through-hole instead of the recess 14.

[0150] In the embodiment of the present disclosure, the restricting portion 33 is provided near the center of the support member 3 in the longitudinal direction, but may be provided near an end portion of the support member 3 in the longitudinal direction.

[0151] When the light source module 1 has a plurality of substrates 11 as in the embodiment of the present disclosure, it is desirable that at least one restricting portion 33 be provided on each substrate 11. This makes it possible to reduce stress on each substrate 11 when the plurality of substrates 11 are misaligned in the longitudinal direction.

[0152] In the embodiment of the present disclosure, the restricting portions 33 are arranged at two locations along the second direction D2 (left-right direction) of the support member 3 (see FIG. 21), but may be arranged at only one location. However, arranging the restricting portions 33 at two locations along the second direction D2 (left-right direction) of the support member 3 makes it more difficult for the substrate 11 to come off when a force is applied to the substrate 11 in the left-right direction.

[0153] In the embodiment of the present disclosure, the regulating portion 33 is formed by cutting and raising from the support portion 30, but it may also be an elastic piece from the support portion 30, or a separate member from the support portion 30 (for example, attached by a screw).

[0154] In the embodiment of the present disclosure, the shape of the support member 3 is as shown in Figures 2 and 8, but is not limited to such shapes. The shape of the support member 3 may be, for example, a U-shape, a V-shape with both ends closed from the U-shape, an inverted V-shape, an L-shape, an M-shape, an I-shape, or the like when viewed in the longitudinal direction. Note that the first surface 30A of the support portion 30 of the support member 3, to which the substrate 11 is attached, may be a substantially flat surface.

[0155] (4) Aspects As is clear from the above-described embodiments and modifications, the present disclosure includes the following aspects. In the following, reference numerals are given in parentheses only to clarify the correspondence with the embodiments.

[0156] The first aspect is a lighting device (A1) comprising a light source module (1), a support member (3) that supports the light source module (1), and a power supply unit (2) that supplies power to the light source module (1). The light source module (1) includes a light source (10) and a conductive member (13) electrically connected to the light source (10). The support member (3) includes a support portion (30) having a first surface (30A) and a second surface (30B) opposite the first surface (30A), an attachment portion (313) for attaching the light source module (1) by sliding it in a predetermined direction, and a through-hole (316) that penetrates the support portion (30) in the direction in which the first surface (30A) and the second surface (30B) are aligned. The power supply unit (2) includes a receiving portion (26) into which the conductive member (13) that penetrates the through-hole (316) is inserted. The light source module (1) is attached to a first surface (30A) of the support portion (30). The power supply unit (2) is attached to a second surface (30B) of the support portion (30). By sliding the light source module (1) in a predetermined direction relative to the support member (3), the conductive member (13) and the receiving portion (26) are electrically connected.

[0157] According to this aspect, when the light source module (1) is attached to the support member (3), the light source module (1) and the power supply unit (2) are electrically connected almost simultaneously. In this way, it is not necessary to separate the work of attaching the light source module (1) to the support member (3) from the work of electrically connecting the light source module (1) and the power supply unit (2). Therefore, it is possible to improve the ease of assembly.

[0158] The second aspect is an illumination device (A1) based on the first aspect. In the second aspect, each of the light source module (1) and the support member (3) is elongated along a direction including a predetermined orientation.

[0159] According to this embodiment, the number of attachment portions (313) can be increased along the longitudinal direction, making it easier for the support member (3) to hold the light source module (1).

[0160] A third aspect is an illumination device (A1) based on the second aspect. In the third aspect, the light source module (1) has a recess (14) that is orthogonal to a first direction (D1) that is the longitudinal direction of the light source module (1) and that opens on both sides in a second direction (D2) that is a direction along the support portion (30). The mounting portion (313) has a base (314) that protrudes from the first surface (30A) in a normal direction to the first surface (30A) and a protrusion (315) that protrudes from the tip of the base (314) in a direction opposite to a predetermined direction. A portion (15) of the light source module (1) is sandwiched between the first surface (30A) and the protrusion (315) when the light source module (1) is attached to the support member (3).

[0161] According to this embodiment, the support member (3) can more easily hold the light source module (1).

[0162] A fourth aspect is an illumination device (A1) based on any one of the first to third aspects. In the fourth aspect, the support member (3) further includes a restricting portion (33) that restricts movement of the light source module (1).

[0163] According to this embodiment, it is possible to prevent the light source module (1) from coming off. That is, even if a force acts on the light source module (1) in the direction opposite to that when the light source module (1) is attached to the support member (3) after the light source module (1) is attached to the support member (3), the restricting portion (33) can prevent the light source module (1) from sliding due to the force.

[0164] A fifth aspect is an illumination device (A1) based on any one of the first to fourth aspects. In the fifth aspect, the conductive member (13) includes a blade terminal (16).

[0165] According to this embodiment, even if the light source module 1 thermally expands in the longitudinal direction, the thermal expansion displacement can be absorbed as long as the displacement is equal to or less than the longitudinal length of the blade terminals 16. In this respect alone, the blade terminals 16 are more effective than the pin terminals 17.

[0166] A sixth aspect is an illumination device (A1) based on any one of the first to fourth aspects. In the sixth aspect, the conductive member (13) includes a pin terminal (17).

[0167] According to this embodiment, it is only necessary to orient the pin terminal 17 in the third direction D3. In other words, while the blade terminal 16 requires the blade to be aligned in the first direction D1, the pin terminal 17 does not. In this respect alone, the pin terminal 17 is more effective than the blade terminal 16.

[0168] The seventh aspect is a lighting fixture (B1) that includes a lighting device (A1) based on any one of the first to sixth aspects and a fixture body (6) that holds the lighting device (A1).

[0169] According to this aspect, by hooking the first hooking member (37) onto the first hooked portion, the workability of attaching the lighting device (A1) to the fixture body (6) can be improved. [Explanation of symbols]
