[0012] The main unit 11 includes an appliance main body 20 which is an attachment portion, and a terminal block 21, a power supply portion 22, a communication device 23, and a pair of spring receiving members 24 which are arranged on the appliance main body 20.
[0013] The fixture body 20 has a so-called inverted Fuji shape with a reflector, and is attached to an installation location such as a ceiling surface. The fixture body 20 is made of metal, for example, sheet metal, and is provided long.
[0014] The fixture body 20 comprises a long and narrow rectangular top plate portion 26, side plate portions 27 bent from both sides in the width direction, which is the short side direction intersecting with the longitudinal direction of the top plate portion 26, reflecting plate portions 28 on both sides protruding obliquely upward from the side plate portions 27, and end plate portions 29 closing both ends in the longitudinal direction. The top plate portion 26, the side plate portions 27 on both sides, and the reflecting plate portions 28 on both sides are integrally formed by bending a single sheet of metal. A concave storage portion 30 that opens downward is formed between the top plate portion 26, the side plate portions 27 on both sides, and the end plate portions 29 on both ends.
[0015] The top plate portion 26 is provided with a plurality of mounting holes 31 for mounting to an installation portion, and wiring holes 32 for drawing in power lines from the installation portion.
[0016] One side plate portion 27 is provided with a hole-like or groove-like opening 33 for passing wireless signals in correspondence with the arrangement position of communication device 23. Note that opening 33 for passing wireless signals does not need to be provided when a predetermined wireless communication performance can be ensured.
[0017] The terminal block 21 is attached to the lower surface of the top plate portion 26 of the device body 20, and is connected to a power line drawn in from the wiring hole 32. The terminal block 21 is electrically connected to the power supply portion 22 by internal wiring.
[0018] Furthermore, the power supply unit 22 converts the external power supplied through the terminal block 21 into lighting power for the light source and supplies it to the light source unit 12. Furthermore, the power supply unit 22 converts the external power supplied through the terminal block 21 into operating power for the communication device and supplies it to the communication device 23. The power supply unit 22 inputs, for example, a dimming signal transmitted from the communication device 23, and controls the lighting power supplied to the light source unit 12 so as to perform dimming control according to the input dimming signal. Note that the power supply unit 22 may include a power supply unit for the light source and a power supply unit for the communication device.
[0019] The communication device 23 is a wireless communication device that transmits and receives wireless signals using radio waves as a medium between, for example, a communication terminal such as a remote control, a smartphone, or a tablet, and the communication device 23 of another lighting device 10. The communication device 23 is electrically connected to the power supply unit 22, and sends a received signal to the power supply unit 22 and transmits a signal from the power supply unit 22. The provision of the communication device 23 enables, for example, group control or scene control, such as adjusting the light according to the scene for each group made up of a plurality of lighting devices 10.
[0020] The communication device 23 is accommodated in the accommodation section 30 of the device body 20 and attached to the underside of the top plate section 26. The communication device 23 is disposed in a position facing the wireless signal passage opening 33 provided in the side plate section 27 between the power supply section 22 of the device body 20 and the spring receiving member 24 on one end side.
[0021] The spring receiving members 24 are attached to the underside of the top plate portion 26 of the device body 20 at positions near both ends in the longitudinal direction.
[0022] Next, the light source unit 12 comprises a chassis 40 which is the main body of the light source unit, a light source 41 arranged on the underside of the chassis 40, a cover 42 which houses the light source 41 between the chassis 40 and the cover 42, and a pair of mounting springs 43 arranged on the upper side of the chassis 40.
[0023] The chassis 40 is made of metal and is provided long in correspondence with the device main body 20.
[0024] The light source 41 is configured by a light source module including a long light source substrate and a plurality of light emitting elements (semiconductor light emitting elements) mounted on the underside of the substrate. For example, a surface mount type LED is used as the light emitting element, and a plurality of light emitting elements are mounted in one row or multiple rows along the longitudinal direction of the light source substrate. The light emitting elements are not limited to LEDs, and may be other elements such as organic EL. When the illumination device 10 is assembled, the light source 41 is electrically connected to the power source unit 22 by a connector connection between the wiring from the power source unit 22 and the wiring from the light source 41.
[0025] The cover 42 includes a long translucent cover 44 and end covers 45 attached to both ends of the translucent cover 44. The translucent cover 44 is made of resin through which radio waves pass, and has translucency and light diffusion properties. The lower surface side of the translucent cover 44 has a cross section in the width direction perpendicular to the longitudinal direction formed in a convex curved shape. The translucent cover 44 becomes a light-emitting area that emits light in a line along the longitudinal direction. The end covers 45 are made of resin through which radio waves pass, but may be non-translucent or translucent. The end covers 45 are attached to the ends of the translucent cover 44 held by the chassis 40, and hold the translucent cover 44 to the chassis 40.
[0026] The pair of mounting springs 43 are attached to positions near both ends in the longitudinal direction on the upper surface side of the chassis 40. The pair of mounting springs 43 are raised from the chassis 40 against the spring force and hooked onto the pair of spring receiving members 24 of the fixture body 20, whereby the light source unit 12 is temporarily suspended from the fixture body 20, and by pushing up the light source unit 12 from this state, the spring force of the pair of mounting springs 43 pulls the light source unit 12 up to the fixture body 20, and the light source unit 12 is attached to the fixture body 20. In addition, the light source unit 12 can be removed from the fixture body 20 by pulling down the light source unit 12 against the biasing force of the pair of mounting springs 43 and removing the pair of mounting springs 43 from the pair of spring receiving members 24.
[0027] Next, the communication device 23 is shown in FIG. 2 to FIG.

The fitting portion 59, the first pressing portion 60, and the locking lever portion 61 protrude from the base portion 58 in the direction in which the second case 52 is assembled.
[0036] The fitting portion 59 stands from a position inside the periphery of the base portion 58 , and defines a fitting edge portion 62 having a substantially rectangular ring shape between the fitting portion 59 and the periphery of the base portion 58 .
[0037] The first pressing portion 60 presses the other surface 54b opposite to the surface 54a on which the wireless communication unit 55, the connector 56, etc. are mounted of the substrate 54 of the communication module 50. The first pressing portions 60 protrude from two locations on both sides in the width direction of each side of the fitting portion 59 located on both sides in the longitudinal direction, and there are, for example, four first pressing portions 60. The first pressing portions 60 are substantially triangular, and the tip surface that comes into contact with the substrate 54 is provided in a flat shape.
[0038] The locking lever portion 61 is erected on the side of the fitting portion 59 so as to protrude in the assembly direction beyond the tip surface of the fitting portion 59. A locking hole 63 is formed on the tip side of the locking lever portion 61.
[0039] The outer surface of the base portion 58 opposite to the protruding direction of the fitting portion 59 and the like is configured as a mounting surface 51 a of the first case 51 that abuts against the top plate portion 26 of the device body 20 .
[0040] The second case 52 is integrally formed from a resin through which radio waves pass. The second case 52 has a rectangular surface 64, and a cubic case body 67 having side surfaces 65 provided on both longitudinal sides of the surface 64 and side surfaces 66 provided on both lateral sides of the surface 64. The second case 52 has a storage section 68 formed therein, and an opening 69 communicating with the storage section 68 is formed on the surface opposite the surface 64.
[0041] A fitting surface portion 70 into which the fitting portion 59 of the first case 51 is fitted and inserted is formed on the inside of the side surface portions 65, 66. A fitting groove portion 71 into which the fitting edge portion 62 of the periphery of the base portion 58 of the first case 51 is fitted is provided on the inside of the opening 69 of the side surface portions 65, 66. A holding portion 72 is provided in the fitting groove portion 71, which abuts against the fitting edge portion 62 and holds the communication device 23 by sandwiching it between the fitting edge portion 62 and the top plate portion 26 of the instrument body 20 to which the communication device 23 is attached.
[0042] The depth dimension of the fitting groove 71 and the thickness dimension of the fitting edge 62 are approximately the same dimension. In this case, when the cases 51, 52 are combined, the mounting surface 52a of the second case 52, which is composed of the tip surfaces of the side portions 65, 66 and the mounting surface of the mounting portion 74 described later, and the mounting surface 51a of the first case 51 are approximately flush with each other. Note that it is preferable that the depth dimension of the fitting groove 71 and the thickness dimension of the fitting edge 62 are the same dimension, but the thickness dimension of the fitting edge 62 may be slightly larger than the depth dimension of the fitting groove 71, or the thickness dimension of the fitting edge 62 may be slightly smaller than the depth dimension of the fitting groove 71.
[0043] A connection window 73 is formed in one side surface portion 65 in the longitudinal direction of the second case 52, and the connector 56 of the communication module 50 is disposed opposite the connection window 73.
[0044] An attachment portion 74 for attachment to the top plate portion 26 of the appliance body 20 is protruded from one side surface portion in the longitudinal direction of the second case 52. The attachment portion 74 protrudes from the same plane position as the tip surface of the side surface portion 65 toward the outside of the side surface portion 65. The attachment portion 74 is provided with a plurality of circular attachment holes 75 aligned in the width direction and an attachment hole 76 which is an elongated hole elongated in the width direction, aligned in the width direction. The attachment portion 74 is attached to the top plate portion 26 of the appliance body 20 by attachment fixtures such as resin rivets or screws that are inserted into the attachment holes 75, 76.
[0045] The tip surfaces of the side surface portions 65 , 66 and the mounting surface of the mounting portion 74 are configured as a mounting surface 52 a of the second case 52 that is attached to the top plate portion 26 of the device body 20 .
[0046] The side portion 66 is different from the side portion 65 on which the mounting portion 74 of the second case 52 is provided, and one of the side portions 66 in the short direction of the second case 52 is provided with a cutout portion 77 through which the locking lever portion 61 is inserted when the cases 51, 52 are combined, and a locking claw 78 is provided with which the locking hole 63 of the locking lever portion 61 engages.
[0047] A locking structure 79 is formed by the locking lever portion 61 of the first case 51 and the locking claw 78 of the second case 52. Therefore, the locking structure 79 including the locking claw 78 for locking the first case 51 housed and arranged in the opening 69 is provided on a side surface 66 different from the side surface 65 on which the mounting portion 74 of the second case 52 is provided.
[0048] Between the surface portion 64 of the second case 52 and one side surface portion 66 in the short side direction, a step portion 80 is provided which is recessed towards the inside of the second case 52. A tip side of the locking lever portion 61 which is locked to a locking claw 78 provided on one side surface portion 66 is disposed to protrude to the side of the step portion 80. The presence of the step portion 80 makes it easier to operate the tip side of the locking lever portion 61, improving workability when assembling or disassembling the cases 51, 52.
[0049] A plurality of second pressing portions 81 and a plurality of side pressing portions 82 are provided on the inner surface of second case 52.
[0050] A plurality of second pressing portions 81 are provided in a rib-like manner protruding from a plurality of locations on the inner surface of the side surface portion 66 on both sides in the short side direction of the second case 52. The second pressing portion 81 of one of the side surface portions 66 on which the step portion 80 is provided is provided protruding between the step portion 80. The second pressing portion presses the one surface 54a of the substrate 54 of the communication module 50 on which the wireless communication portion 55, the connector 56, and the like are mounted.
[0051] The first pressing portion 60 and the second pressing portion 81 press different positions on one surface 54a and the other surface 54b of the substrate 54 that do not face each other. The first pressing portion 60 presses both sides of the substrate 54 in the longitudinal direction, and the second pressing portion 81 presses both sides of the substrate 54 in the lateral direction. The first pressing portion 60 and the second pressing portion 81 press the substrate 54 so as to sandwich and hold it. Note that the substrate 54 may be pressed so as to restrict movement when there is a gap between the first pressing portion 60 and the second pressing portion 81 and the substrate 54.
[0052] The communication module 50 held between the first pressing portion 60 and the second pressing portion 81 is positioned at a position farther from the mounting surface 52a than half the height direction from the mounting surface 52a of the second case 52.
[0053] The side pressing portions 82 are provided in a plurality of rib-like protrusions from a plurality of locations on the inner surface of the side surface portion 65 on the opposite side to the side surface portion 65 on which the attachment portion 74 in the longitudinal direction of the second case 52 is provided. The side surface pressing portions 82 enter the recessed portions 54c of the substrate 54 to press the side surfaces of the substrate 54, and determine the position of the substrate 54 in the direction parallel to the faces 54a and 54b.
[0054] The shape of the substrate 54 and the cases 51, 52 of the communication module 50 in the direction intersecting the assembly direction is not limited to a rectangle but may be a square, in which case the longitudinal direction is the first direction and the lateral direction is the second direction.
[0055] As shown in FIG. 1, the communication device 23 is attached so that the longitudinal side surface portion 65 on which the attachment portion 74 is provided faces the longitudinal direction of the device body 20 and the stepped portion 80 faces the lateral direction of the device body 20.
[0056] To assemble the communication device 23, the communication module 50 is placed on the multiple first pressing portions 60 of the first case 51, the second case 52 is placed over the first case 51, and the first case 51 and the second case 52 are combined. Alternatively, with the opening 69 of the second case 52 facing upward, the communication module 50 is inserted into the second case 52 through the opening 69 and placed on the multiple second pressing portions 81, the first case 51 is fitted into the opening 69 of the second case 52, and the first case 51 and the second case 52 are combined.
[0057] When the first case 51 and the second case 52 are combined, the locking lever portion 61 of the first case 51 is engaged with the locking claw 78 of the second case 52, and the first case 51 and the second case 52 are temporarily secured in the combined state.
[0058] By combining the first case 51 and the second case 52, the mating edge portion 62 of the first case 51 is fitted into the mating groove portion 71 of the second case 52, the base portion 58 of the first case 51 is positioned in the opening 69 of the second case 52, and the substrate 54 of the communication module 50 is sandwiched and held between the multiple first pressing portions 60 of the first case 51 and the multiple second pressing portions 81 of the second case 52.
[0059] In addition, when attaching the communication device 23 to the top plate portion 26 of the main body 20, the mounting surfaces 51a, 52a of the cases 51, 52 are placed on the top plate portion 26 of the main body 20, and the mounting portion 74 of the second case 52 is attached to the top plate portion 26 of the main body 20 using mounting fixtures such as plastic rivets or screws that pass through the mounting holes 75, 76 of the mounting portion 74 of the second case 52.
[0060] By attaching the mounting portion 74 of the second case 52 to the top plate portion 26 of the appliance body 20, the first case 51 is sandwiched and held between the second case 52 and the top plate portion 26 of the appliance body 20. In this case, the fitting edge portion 62 of the first case 51 is sandwiched and held between the holding portion 72 of the fitting groove portion 71 of the second case 52 and the top plate portion 26 of the appliance body 20, or the first case 51 together with the communications module 50 is sandwiched and held between the second pressing portion 81 of the second case 52 and the top plate portion 26 of the appliance body 20.
[0061] By attaching the mounting portion 74 of the second case 52 to the top plate portion 26 of the main body 20 of the fixture, the first case 51 and the second case 52 are changed from a temporary fastening state to a fixed state, and the communication module 50 housed between the first case 51 and the second case 52 can be securely held.
[0062] In this way, when the communication device 23 is attached to the top plate portion 26 of the fixture body 20, the first case 51 and the second case 52 are fixed in place, so there is no need to provide multiple fixing structures for fixing the first case 51 and the second case 52 when assembling the communication device 23, which simplifies the structure and simplifies assembly.
[0063] In addition, the communication module 50 housed between the first case 51 and the second case 52 is held between the first holding portion 60 of the first case 51 and the second holding portion 81 of the second case 52, so that the communication module 50 can be held.
[0064] Since the first pressing portion 60 and the second pressing portion 81 press different positions of the communications module 50, a wide range of the communications module 50 can be pressed and the dimensional variations of each component can be accommodated.
[0065] In addition, the first pressing portion 60 of the first case 51 positions the communication module 50 at a position farther away from the mounting surface 52a than half the height direction from the mounting surface 52a of the second case 52, thereby separating the communication module 50 from the top plate portion 26 of the metal device body 20 and improving wireless communication performance.
[0066] Furthermore, since the wireless communication unit 55 is mounted on one surface 54a of the substrate 54 opposite the second case 52, the wireless communication unit 55 can be separated from the top plate portion 26 of the metal device body 20, improving wireless communication performance.
[0067] In addition, a locking structure 79 for locking the first case 51 housed and placed in the opening 69 is provided on a side surface 66 different from the side surface 65 on which the mounting portion 74 of the second case 52 is provided. This allows the first case 51 and the second case 52 to be temporarily fixed in place in their combined state by the locking structure 79, and prevents the locking structure 79 from getting in the way when the mounting portion 74 is being attached.
[0068] In the lighting device 10, the power supply section 22 and the communication device 23 may be disposed in the light source unit 12.
[0069] Furthermore, the lighting device 10 is not limited to an elongated shape, but may be a square or circular shape. Furthermore, the lighting device 10 is not limited to a surface-mounted lighting device, but may be a recessed lighting device or a hanging lighting device.
