Mode for Carrying Out the Invention

[0011] Hereinafter, the lighting device and the lighting fixture according to the embodiment of the present disclosure will be described in detail with reference to the drawings. However, each of the drawings described in the following embodiments is a schematic diagram, and the respective ratios of the sizes and thicknesses of each component 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 can be made according to the design and the like as long as the effects of the present disclosure can be achieved.

[0012] (1) Outline The lighting device (light source unit A1) according to the embodiment includes a light source (LED module 1), a power supply device 2 that supplies lighting power to the light source (LED module 1), a wireless communication unit 3, and a mounting member 4 (see FIGS. 1 and 2).

[0013] The wireless communication unit 3 has an antenna unit 31 that emits electromagnetic waves into space or receives electromagnetic waves from space, and a wireless circuit unit 30 that performs at least one of transmission or reception of a wireless signal using electromagnetic waves as a medium via the antenna unit 31 (see FIG. 3). In the present embodiment, the electromagnetic waves used by the wireless communication unit 3 as a medium may be radio waves or electromagnetic waves other than radio waves such as infrared light and visible light.

[0014] The mounting member 4 has the LED module 1 mounted on the first surface 40A and the power supply unit 2 mounted on the second surface 40B opposite to the first surface 40A (see Figure 4). The power supply unit 2 has a lighting circuit 21 that controls the lighting power and a case 20 that houses the lighting circuit 21 and the wireless circuit unit 30 (see Figures 3 and 4). At least a part of the antenna unit 31 is outside the case 20.

[0015] In conventional designs, the wireless communication unit case housing the wireless communication unit and the case housing the lighting circuit were completely separate structures. Therefore, the lighting circuit and wireless communication unit had to be attached separately to the sheet metal of the lighting fixture, making the assembly process of the lighting fixture (lighting device) time-consuming.

[0016] In contrast, in the lighting device (light source unit A1) according to this embodiment, the lighting circuit 21 and the wireless circuit unit 30 are housed in the case 20 of the power supply unit 2, so the installation of the lighting circuit 21 and the wireless circuit unit 30 to the mounting member 4 is completed by attaching the case 20 to the mounting member 4. As a result, the lighting device (light source unit A1) according to this embodiment can improve the workability of the assembly work compared to the conventional example. Moreover, in the lighting device (light source unit A1) according to this embodiment, at least a part of the antenna unit 31 is outside the case 20, so the attenuation of electromagnetic waves emitted by the antenna unit 31 into space or electromagnetic waves received by the antenna unit 31 from space can be suppressed compared to the case where the entire antenna unit 31 is inside the case 20.

[0017] Furthermore, the lighting fixture B1 according to this embodiment comprises a lighting device (light source unit A1) and a fixture body 9 that supports the lighting device (light source unit A1) (see Figures 1 and 2).

[0018] However, the lighting fixture B1 according to this embodiment can improve the workability of the assembly process compared to the conventional example.

[0019] (2) Details (2-1) Lighting fixtures First, the lighting fixture B1 according to the embodiment (hereinafter referred to as lighting fixture B1) will be described.

[0020] As shown in Figures 1 and 2, the lighting fixture B1 comprises a lighting device according to the embodiment, namely a light source unit A1 (hereinafter abbreviated as light source unit A1) and a fixture body 9 that supports the light source unit A1. The light source unit A1 is detachably attached to the fixture body 9 which is directly attached to the ceiling. However, the fixture body 9 may be embedded in the ceiling. Alternatively, the fixture body 9 may be directly attached to the wall or embedded in the wall.

[0021] The main body of the device 9 comprises a long, box-shaped housing section 90 with an open bottom, a pair of reflectors 91 projecting diagonally upward from the open edges on both sides along the longitudinal direction of the housing section 90, and a pair of end plates 92 provided at both ends of the housing section 90 and the pair of reflectors 91 in the longitudinal direction (see Figure 2). The housing section 90 and the pair of reflectors 91 are integrally formed by punching and bending metal plates.

[0022] The fixture body 9 is installed on the ceiling by inserting suspension bolts (not shown) through at least two of the multiple mounting holes 900 provided on the bottom surface of the housing 90, and tightening nuts (not shown) onto these suspension bolts. In addition, a power line is inserted through one of the multiple power supply holes 901 provided on the bottom surface of the housing 90. However, if multiple lighting fixtures B1 are installed, another power line for daisy-chaining may be inserted through a different power supply hole 901.

[0023] A terminal block 902 is mounted on the bottom surface of the housing 90. The terminal block 902 is electrically connected to the power cable 903. A power connector 904 is provided at the end of the power cable 903.

[0024] However, the power line inserted through the power hole 901 of the fixture body 9 is electrically connected to the terminal block 902, and via the terminal block 902, power cable 903, and power connector 904, is electrically connected to the power supply unit 2 of the light source unit A1 (specifically, the power terminal section 22 described later).

[0025] (2-2) Light source unit The light source unit A1 comprises an LED module 1, a power supply unit 2, a wireless communication unit 3, a mounting member 4, and a cover 7 (see Figure 2).

[0026] (2-2-1) LED module LED module 1 comprises a number of LEDs 10 and a substrate 11. The substrate 11 is formed in the shape of a long rectangular plate. The number of LEDs 10 are mounted in a single row at equal intervals along the longitudinal direction of the substrate 11, in the center of the short side on the surface (bottom surface) of the substrate 11 (see Figure 2).

[0027] (2-2-2) Mounting components The mounting member 4 is formed into a long, rectangular trough shape by processing a metal plate (for example, a steel plate). The mounting member 4 has a long, rectangular base plate 40 and a pair of side plates 41 that rise upward from both ends along the longitudinal direction of the base plate 40. The LED module 1 is attached to the lower surface (first surface 40A) of the base plate 40 by a plurality of claws 42 cut out from the base plate 40 (see Figures 4 and 5). However, the mounting member 4 may be formed from a material other than a metal plate, for example, a synthetic resin.

[0028] (2-2-3) Cover The cover 7 is formed in a semi-cylindrical shape from a translucent synthetic resin such as acrylic resin or polycarbonate resin (see Figure 2). The cover 7 also has a pair of protruding walls 70 that project upward along its longitudinal direction. The cover 7 houses the mounting member 4 between the pair of protruding walls 70, and is attached to the mounting member 4 by hooking the tips (upper ends) of the pair of side plates 41 of the mounting member 4 with the hooks formed on the tips (upper ends) of the pair of protruding walls 70. The cover 7 may also be made of inorganic glass such as quartz glass.

[0029] (2-2-4) Power supply device The power supply unit 2 includes a lighting circuit 21 and a case 20 that houses the lighting circuit 21 (see Figure 2).

[0030] The lighting circuit 21 includes a printed circuit board 25 on which wiring conductors are printed on a rectangular insulating substrate, and a plurality of circuit components 26 mounted on both the front and back surfaces of the printed circuit board 25 (see Figure 2). In other words, the lighting circuit 21 is composed of printed circuits.

[0031] Figure 3 shows the circuit configuration of the lighting circuit 21. The lighting circuit 21 includes a power conversion circuit 210, a constant current circuit 211, a control circuit 212, and the like.

[0032] The power conversion circuit 210 includes, for example, a rectifier circuit such as a diode bridge, a boost chopper circuit (power factor correction circuit), and the like. The power conversion circuit 210 converts AC power supplied from an external power supply P1 through the power supply terminal section 22 into DC power. The external power supply P1 is, for example, a commercial power grid that supplies AC voltage and AC current with an effective value of 100V or 200V. However, the power conversion circuit 210 may be equipped with a switching power supply circuit having a power factor correction function, such as a buck chopper circuit, a buck-boost chopper circuit, or a flyback converter, instead of a boost chopper circuit.

[0033] The constant current circuit 211 includes, for example, a buck converter. The constant current circuit 211 steps down the DC voltage output from the power conversion circuit 210 and applies it to the LED module 1, and also adjusts the DC current flowing through the LED module 1. However, the constant current circuit 211 may be equipped with various chopper circuits, series regulators, etc., instead of a buck converter.

[0034] The control circuit 212 includes, for example, a microcontroller. The control circuit 212 controls the power conversion circuit 210 to maintain its output voltage at a constant DC voltage. Furthermore, the control circuit 212 controls the step-down chopper circuit of the constant current circuit 211 to match the DC current supplied from the constant current circuit 211 to the LED module 1 to a target value. The control circuit 212 also changes the target value of the DC current supplied to the LED module 1 in response to a dimming signal received from the wireless communication unit 3 via the signal connector 5.

[0035] Here, the power terminal section 22 is mounted on one end of the printed circuit board 25 in the longitudinal direction (see Figures 2 and 5). In this embodiment, the power terminal section 22 is a connector to which the power connector 904 is detachably connected, but instead of the power connector 904, it may be a terminal block to which the conductors of an electric wire are electrically connected. Alternatively, the power terminal section may be a lead wire drawn out from the lighting circuit 21 and may be soldered to the conductor of the power cable 903. Note that the configuration of the power terminal section 22 also includes configurations other than those described above. Furthermore, the socket 50 of the signal connector 5 is mounted on the other end of the printed circuit board 25 in the longitudinal direction (see Figure 5). However, in Figures 4 and 5, the circuit components mounted on the front (bottom) and back (top) surfaces of the printed circuit board 25 are not shown.

[0036] Case 20 has a rectangular bottom wall 200 and a pair of first side walls 201 that project downward along the short direction of the bottom wall 200 from both ends in the longitudinal direction of the bottom wall 200. Case 20 also has a pair of second side walls 202 that project downward along the longitudinal direction of the bottom wall 200 from both ends in the short direction of the bottom wall 200 (see Figures 4 and 5). In other words, case 20 is formed in the shape of a long box with an opening 204 in front (below) the bottom wall 200. Case 20 also has a fixing piece 203 that projects outward from the tip of one of the second side walls 202 (see Figure 4). The fixing piece 203 is formed in the shape of a trough.

[0037] The case 20 houses the printed circuit board 25 of the lighting circuit 21 and the printed circuit board 32 of the wireless circuit section 30, which will be described later, side by side in the longitudinal direction (see Figure 5). The case 20 has a plurality of claws 205 cut out from a pair of second side walls 202 (see Figure 5). The case 20 supports the two printed circuit boards 25 and 32 by sandwiching them between these claws 205. The power terminal section 22 protrudes out of the case 20 through a window hole provided in one of the first side walls 201 (see Figure 5).

[0038] The power supply unit 2 is mounted on the upper surface (second surface 40B) of the mounting member 4 of the light source unit A1, with the opening 204 of the case 20 facing the mounting member 4 (see Figures 2 and 5). Specifically, the case 20 is fixed to the mounting member 4 by screwing one of the second side walls 202 and the fixing piece 203 to each side plate 41 of the mounting member 4. In addition, when mounted on the mounting member 4, the opening 204 of the case 20 is closed by the bottom plate 40 of the mounting member 4 (see Figures 4 and 5).

[0039] (2-2-5) Wireless Communication Department The wireless communication unit 3 comprises a wireless circuit unit 30 and an antenna unit 31 (see Figure 3). The wireless circuit unit 30 comprises a printed circuit board 32 on which wiring conductors are printed on a rectangular insulating substrate, and circuit components 33 mounted on the printed circuit board 32 (see Figure 2). In other words, the wireless circuit unit 30 is composed of a printed circuit. A plug 51 of the signal connector 5 is mounted on the end of the printed circuit board 32 (see Figures 4 and 5). The plug 51 is mechanically and electrically connected to a socket 50 mounted on the printed circuit board 25 of the lighting circuit 21. The shape of the printed circuit board 25 is not limited to a rectangle, but includes various shapes such as polygons other than rectangles, circles, etc.

[0040] The antenna section 31 is configured to emit electromagnetic waves (for example, radio waves in the 920 MHz band or 2.4 GHz band) into space and to receive electromagnetic waves from space. The antenna section 31 is a so-called pattern antenna formed of conductors printed on a substrate separate from the printed circuit board 32 (hereinafter referred to as the antenna substrate 310). The antenna substrate 310 is preferably housed in a housing which is a box made of synthetic resin, but it may also be left exposed without being housed in a housing. The antenna section 31 is electrically connected to the wireless circuit section 30 via wires not shown. However, the antenna section 31 may also be formed on the substrate 11 of the LED module 1. The antenna section 31 is not limited to a pattern antenna, and may also be a patch antenna (microstrip antenna), chip antenna, rod antenna, film antenna, etc.

[0041] The antenna unit 31 (and its housing) is attached to the outer surface of the second side wall 202 of the case 20. The second side wall 202 is provided with a pair of claws 205 that protrude outward. The antenna unit 31 is attached to the second side wall 202 of the case 20 by the antenna substrate 310 being sandwiched between the pair of claws 205 (see Figure 4). However, the antenna unit 31 may also be attached to a part other than the case 20, for example, the bottom plate 40 or side plate 41 of the mounting member 4.

[0042] The wireless circuit unit 30 extracts a wireless signal from electromagnetic waves received by the antenna unit 31, for example, radio waves in the 920 MHz band or the 2.4 GHz band, and acquires control information from the wireless signal. Furthermore, the wireless circuit unit 30 converts the control information into a dimming signal and transmits the converted dimming signal to the lighting circuit 21 (control circuit 212) via the signal connector 5.

[0043] The lighting circuit 21 controls the LED module 1 by changing the target value of the DC current supplied to the LED module 1 by the control circuit 212 in response to a dimming signal received from the wireless communication unit 3, thereby causing the LED module 1 to blink (switch between on and off) and dim.

[0044] As described above, the wireless circuit section 30 of the wireless communication unit 3 is housed together with the lighting circuit 21 in the case 20 of the power supply unit 2. On the other hand, the antenna section 31 of the wireless communication unit 3 is located outside the case 20. Therefore, the light source unit A1 can suppress attenuation of the wireless signal reaching the antenna section 31 even when the case 20 is made of metal.

[0045] (2-3) Installation of lighting fixtures Lighting fixture B1 is installed on the ceiling of the room using the following procedure.

[0046] First, the power wires drawn from the ceiling are routed through the power hole 901 of the fixture body 9 into the housing 90, and then the fixture body 9 is attached to the suspension bolts provided in the ceiling. Then, the power wires routed from the power hole 901 are electrically connected to the terminal block 902.

[0047] Next, after the power connector 904 of the power cable 903 is plugged into the power terminal section 22 of the power supply unit 2, the light source unit A1 is attached to the fixture body 9 so that the power supply unit 2 is housed in the housing section 90. Note that the mounting structure of the light source unit A1 to the fixture body 9 is conventionally known, so a detailed explanation and illustration are omitted.

[0048] The lighting fixture B1 is installed on the ceiling using the above procedure.

[0049] Here, the case 20 of the power supply unit 2 houses the power terminal section 22, the lighting circuit 21, and the wireless circuit section 30 in that order. Therefore, when the light source unit A1 is attached to the fixture body 9, the power terminal section 22 can be positioned near the terminal block 902 attached to the housing section 90 of the fixture body 9 (see Figure 6). As a result, the power cable 903 of the light source unit A1 can be shortened. Also, the case 20 is positioned between the multiple mounting holes 900 provided in the housing section 90 (see Figure 6). Therefore, the distance between the suspension bolts inserted into the mounting holes 900 of the fixture body 9 and the case 20 of the light source unit A1 can be sufficiently large (see Figure 6). As a result, the light source unit A1 can have a sufficient insulation distance between the suspension bolts and the case 20.

[0050] (2-4) Operation of lighting fixtures The power lines connected to the terminal block 902 of the fixture body 9 are switched on and off by a switch installed on the wall of the room (hereinafter referred to as the wall switch). In other words, the lighting fixture B1 (light source unit A1) is switched alternately between the on state and the off state by operating the wall switch.

[0051] Furthermore, when the lighting fixture B1 (light source unit A1) is powered via a wall switch, it can be remotely controlled for flashing and dimming by a wireless signal transmitted from a remote controller (hereinafter referred to as "remote control"), which is not shown in the diagram.

[0052] The remote control, for example, accepts user input and generates control information corresponding to the received input. Furthermore, the remote control transmits a wireless signal containing the generated control information. The control information generated by the remote control includes instructions for switching the lighting fixture B1 (light source unit A1) on and off, and instructions for the dimming level.

[0053] The wireless signal transmitted from the remote control is received by the wireless communication unit 3 of the light source unit A1. The wireless communication unit 3 converts the control information contained in the wireless signal into a dimming signal and transmits the converted dimming signal to the lighting circuit 21 (control circuit 212) via the signal connector 5. The dimming signal corresponds to any value from 0% to 100%, with the rated light output of the light source unit A1 being 100%. However, when the control information is an instruction to switch from off to on, the dimming signal is set to 100%, and when the control information is an instruction to switch from on to off, the dimming signal is set to 0%.

[0054] The lighting circuit 21 controls the LED module 1 by changing the target value of the DC current supplied to the LED module 1 by the control circuit 212 in accordance with the dimming signal received from the wireless communication unit 3, thereby causing the LED module 1 to blink (switch between on and off) and dim. When the dimming signal is set to 0%, the control circuit 212 turns off the LED module 1 by stopping the power conversion circuit 210 and the constant current circuit 211.

[0055] Here, since the mounting member 4 of the light source unit A1 is made of a metal material, the wireless signal (radio wave) that passes electromagnetically through the mounting member 4 and reaches the antenna unit 31 is attenuated. In particular, it is known that the attenuation of the wireless signal (radio wave) increases when the distance from the pattern-forming surface of the antenna unit 31 (the lower surface of the antenna substrate 310) to the mounting member 4 (bottom plate 40) is short. Therefore, it is desirable that the above distance be, for example, 4 mm or more. However, the lower limit of the above distance varies depending on the magnitude of the radio wave output of the antenna unit 31, the frequency band of the radio wave, the type of material of the mounting member 4, the thickness of the mounting member 4, etc.

[0056] Furthermore, it is preferable to form a recess 43 in a part of the mounting member 4 (bottom plate 40) that is located in a position where electromagnetic waves (radio waves) emitted from the antenna section 31 can reach (see Figure 7). In other words, the amount of attenuation when a wireless signal (radio wave) electromagnetically passes through the recess 43 of the mounting member 4 is less than the amount of attenuation when it electromagnetically passes through a part of the bottom plate 40 of the mounting member 4 where no recess 43 is formed. Therefore, by forming a recess 43 in a part of the mounting member 4 (bottom plate 40), the light source unit A1 can suppress the attenuation of wireless signals electromagnetically passing through the mounting member 4.

[0057] Alternatively, instead of the recess 43, an opening 44 may be formed in a part of the mounting member 4 (bottom plate 40) (see Figure 8). The opening 44 penetrates the bottom plate 40 in the thickness direction (vertical direction). Furthermore, it is preferable that the opening 44 is formed in the bottom plate 40 of the mounting member 4 at a position where electromagnetic waves (radio waves) emitted from the antenna part 31 can reach. Therefore, by forming an opening 44 in a part of the mounting member 4 (bottom plate 40), the light source unit A1 can further suppress the attenuation of wireless signals passing electromagnetically through the mounting member 4. Note that if a recess 43 or an opening 44 is formed in the mounting member 4 (bottom plate 40), the limitation of radio waves may be suppressed even if the lower limit of the above distance is shorter than when no recess 43 or opening 44 is formed. However, there is a risk that foreign matter (dust, insects, etc.) may enter the space surrounded by the cover 7 and the mounting member 4 through the opening 44 in the bottom plate 40. Therefore, it is preferable to cover the opening 44 with a lid 45 made of a material that does not easily attenuate radio waves (for example, synthetic resin) (see Figure 8). However, by covering the opening 44 with the lid 45, the light source unit A1 can prevent foreign matter from entering while suppressing the attenuation of radio waves. The opening 44 may also be covered with a material other than the lid 45, for example, an electrically insulating adhesive sheet.

[0058] Furthermore, an opening 410 may be formed in the side plate 41 of the mounting member 4 (see Figure 9). Preferably, the opening 410 is located at a position where electromagnetic waves (radio waves) emitted from the antenna part 31 can reach it. Moreover, it is preferable that the opening 410 is covered with a lid 411 made of a material that does not easily attenuate radio waves, such as synthetic resin, or with an electrically insulating adhesive sheet.

[0059] (3) Variant Next, several modifications of the light source unit A1 according to the embodiment will be described. However, each modification described below is characterized by the configuration of the power supply unit 2 and the wireless communication unit 3, while other configurations are common to the light source unit A1 according to the embodiment. Therefore, in the description of each modification, the components common to the light source unit A1 according to the embodiment will not be shown or described.

[0060] (3-1) Variation 1 The light source unit A1 of the modified example 1 is characterized in that the printed circuit board 25 of the lighting circuit 21 and the printed circuit board 32 of the wireless circuit section 30 are housed in the case 20 with their orientations intersecting, and the antenna section 31 is provided on the printed circuit board 32 of the wireless circuit section 30 (see Figures 10A and 10B). Note that the orientation of the printed circuit boards 25 and 32 refers to the direction normal to the mounting surface of the printed circuit boards 25 and 32, respectively.

[0061] The printed circuit board 32 is formed in a rectangular, flat shape, with the wireless circuit section 30 and the antenna section 31 arranged in the longitudinal direction. The printed circuit board 32 houses the wireless circuit section 30 in the case 20, and the antenna section 31 is held by the claws 205 of the case 20 with the antenna section 31 protruding out of the case 20 through the opening 204. The antenna section 31 is inserted through a through hole 400 that penetrates the bottom plate 40 of the mounting member 4 from the second surface 40B to the first surface 40A, and protrudes below the first surface 40A of the bottom plate 40.

[0062] On the other hand, the printed circuit board 25 of the lighting circuit 21 is positioned almost parallel to the bottom wall 200 and is housed in the case 20 adjacent to the printed circuit board 32 of the wireless communication unit 3 along the longitudinal direction of the case 20. The printed circuit board 25 of the lighting circuit 21 is held in place by a claw 205 provided on the first side wall 201 of the case 20. The electrical connection between the lighting circuit 21 and the wireless circuit unit 30 is made by lead wires 52 (see Figure 10A).

[0063] However, in the light source unit A1 of the modified example 1, the antenna portion 31 is located below the first surface 40A of the bottom plate 40, so that the attenuation of radio waves emitted into space by the antenna portion 31 or radio waves received from space is suppressed, thereby improving the sensitivity of wireless signal transmission or reception. It is preferable that at least the end of the printed circuit board 25 on which the antenna portion 31 is formed is configured to allow light (illumination light) emitted from the LED 10 to pass through.

[0064] Furthermore, in the light source unit A1 of the modified example 1, compared to the case in which the two printed circuit boards 25 and 32 are housed in the case 20 without their orientations intersecting, as in the embodiment, the workability of housing the printed circuit boards 25 and 32 in the case 20 can be improved.

[0065] The wireless communication unit 3 may be housed in the case 20 such that the first side wall 201 and the printed circuit board 32 are approximately parallel (see Figure 10B). The printed circuit board 32 is held in place by claws 205 provided on the bottom wall 200.

[0066] (3-2) Modification example 2 The light source unit A1 of Modified Example 2 is characterized in that the printed circuit board 25 of the lighting circuit 21 and the printed circuit board 32 of the wireless circuit unit 30 are arranged in the case 20 in the height direction (up and down direction) and housed in the case 20 (see Figures 11A and 11B). In other words, the light source unit A1 of Modified Example 2 is characterized in that the lighting circuit 21 and the wireless communication unit 3 are housed in the case 20 such that, when viewed from the direction opposite to the second surface 40B of the bottom plate 40 (up and down direction), the lighting circuit 21 overlaps with at least a part of the wireless communication unit 3. In this embodiment, "overlapping" means that, when viewed from the up and down direction, a part or all of the printed circuit board 32 of the wireless circuit unit 30 is within the projection range of the printed circuit board 25 of the lighting circuit 21.

[0067] The printed circuit board 25 of the lighting circuit 21 is held in place by claws 205 provided on the first side wall 201 of the case 20. On the other hand, the printed circuit board 32 of the wireless circuit section 30 (wireless communication section 3) is held in place by the case 20 via the printed circuit board 25 by being electrically and mechanically connected to the printed circuit board 25 by a signal connector 5. However, the method of fixing the printed circuit board 25 to the case 20 is not limited to being held by the claws 205. For example, the printed circuit board 25 may be screwed to a boss (bridge) protruding from the bottom wall 200 of the case 20. Alternatively, the printed circuit board 32 of the wireless circuit section 30 may be held in place by the case 20, and the printed circuit board 25 of the lighting circuit 21 may be held in place by the case 20 via the printed circuit board 32. Alternatively, the two printed circuit boards 25 and 32 may each be held in place independently by the case 20. The antenna section 31 is provided on the printed circuit board 32 of the wireless circuit section 30, as in the first modified example, but it may also be provided on a separate printed circuit board from the printed circuit board 32 of the wireless circuit section 30, as in the embodiment. When the antenna section 31 is provided on a separate printed circuit board from the printed circuit board 32 of the wireless circuit section 30, it is preferable to attach it to the lower surface (first surface 40A) of the bottom plate 40 of the mounting member 4 so that the surface on which the pattern antenna is formed faces downwards.

[0068] However, the light source unit A1 of the modified example 2, like the modified example 1, can also improve the workability of housing the printed circuit boards 25 and 32 in the case 20.

[0069] (3-3) Modification example 3 The light source unit A1 of Modified Example 3 differs from the light source unit A1 of Modified Example 2 in that the printed circuit board 32 of the wireless circuit section 30 is housed in the case 20 so as to face the first side wall 201 of the case 20 (see Figure 12). The antenna section 31 is provided on the printed circuit board 32 of the wireless circuit section 30, as in Modified Example 1, but it may also be provided on a separate printed circuit board from the printed circuit board 32 of the wireless circuit section 30, as in the embodiment. When the antenna section 31 is provided on a separate printed circuit board from the printed circuit board 32 of the wireless circuit section 30, it is preferable to attach it to the lower surface (first surface 40A) of the bottom plate 40 of the mounting member 4 so that the surface on which the pattern antenna is formed faces downwards.

[0070] However, the light source unit A1 of the modified example 3, like the modified examples 1 and 2, can also improve the workability of housing the printed circuit boards 25 and 32 into the case 20.

[0071] (3-4) Modification 4 The light source unit A1 of the modified example 4 is characterized in that the case 20 has a support portion 208 that supports the lighting circuit 21 and the wireless circuit portion 30 (see Figures 13A and 13B).

[0072] The support portion 208 has a horizontal piece 2080 formed in a flat shape and projecting into the case 20 from the second side wall 202 of the case 20, and a vertical piece 2081 formed in a flat shape and projecting upward from the tip of the horizontal piece 2080 (see Figure 13A). The support portion 208 may be formed integrally with the case 20 by cutting and bending from the second side wall 202, for example. Alternatively, the support portion 208 may be formed from a molded body of synthetic resin.

[0073] The horizontal piece 2080 of the support section 208 is positioned beneath the printed circuit board 32 of the wireless circuit section 30 and supports the printed circuit board 32 from below (see Figure 13A). The vertical piece 2081 faces the printed circuit board 32 along the thickness direction of the printed circuit board 32 and restricts the tilt of the printed circuit board 32.

[0074] Furthermore, if the support portion 208 is formed from a molded synthetic resin, the support portion 208 may have a fixing piece 2082 that protrudes upward from the rear end of the lateral piece 2080, and the fixing piece 2082 may be fixed to the second side wall 202 (see Figure 13B). If the support portion 208 is formed from a molded synthetic resin having electrical insulating properties, the support portion 208 can electrically insulate the wireless circuit portion 30 from the second side wall 202 of the case 20. Note that the antenna portion 31 may be formed separately from the wireless circuit portion 30, or, as in the first modified example, the antenna portion 31 may be provided on the printed circuit board 32 of the wireless circuit portion 30.

[0075] However, in the modified example 4, the light source unit A1 prevents the connection between the plug 51 and the socket 50 from coming loose by supporting the printed circuit board 32 (wireless circuit section 30) on the support section 208. Furthermore, excessive stress may be applied to the solder joints between the printed circuit board 25 and the socket 50 and between the printed circuit board 32 and the plug 51 due to vibrations during transport, which may accelerate the deterioration of these solder joints. However, by having the case 20 have a support section 208 that supports the lighting circuit 21 and the wireless circuit section 30, it is possible to prevent accelerated deterioration of the solder joints of the lighting circuit 21 and the wireless circuit section 30 due to vibrations.

[0076] (3-5) Modification 5 The modified light source unit A1 of the 5th example is characterized in that the power supply unit 2 has an insulator 24 made of an electrical insulating material, and the insulator 24 is placed between the lighting circuit 21 and the wireless circuit section 30 within the case 20 (see Figure 14).

[0077] The insulator 24 is formed in a flat plate shape from, for example, a synthetic resin material. The insulator 24 is positioned between the printed circuit board 25 of the lighting circuit 21 and the printed circuit board 32 of the wireless circuit section 30 so as to be parallel to the pair of first side walls 201.

[0078] However, in the modified light source unit A1 of Modification 5, the insulating distance between the lighting circuit 21 and the wireless circuit section 30 can be increased by the insulator 24. As a result, the light source unit A1 of Modification 5 can suppress short-circuit failures between the lighting circuit 21 and the wireless circuit section 30, and malfunctions caused by noise in the lighting circuit 21 and the wireless circuit section 30.

[0079] Furthermore, grooves or holes may be provided in a part of the insulator 24. Alternatively, the insulator 24 may be formed in a box shape and configured to house the wireless communication unit 3 inside.

[0080] (3-6) Modification 6 The light source unit A1 of Modified Example 6 is characterized in that the wireless communication unit 3 has multiple antenna units 31 (see Figure 15). The wireless communication unit 3 in Modified Example 6 has a first antenna unit 31A and a second antenna unit 31B. The first antenna unit 31A is a patch antenna formed on a substrate separate from the printed circuit board 32 of the wireless circuit unit 30 (hereinafter referred to as the first antenna substrate 310A). The second antenna unit 31B is a patch antenna formed on a substrate separate from the first antenna substrate 310A (hereinafter referred to as the second antenna substrate 310B).

[0081] Here, it is preferable that the direction in which the reception sensitivity of the first antenna section 31A peaks and the direction in which the reception sensitivity of the second antenna section 31B peaks are offset by approximately 90 degrees from each other. This allows the light source unit A1 of the modified example 6 to expand the range in which electromagnetic waves (radio waves) can be received in the wireless communication section 3.

[0082] Furthermore, the first antenna section 31A and the second antenna section 31B may be configured to emit radio waves of different frequency bands into space or to receive radio waves from space.

[0083] The second antenna unit 31B may be configured to emit or receive electromagnetic waves other than radio waves, such as infrared light or visible light, into or from space. In this case, the second antenna unit 31B has a photoelectric conversion element that converts infrared light or visible light into an electrical signal, or a light-emitting element that converts an electrical signal into infrared light or visible light. Therefore, the light source unit A1 of the modified example 6 can communicate using different types of electromagnetic waves (for example, radio waves and infrared light or visible light) as a medium.

[0084] (3-7) Modification 7 The light source unit A1 of Modified Example 7 is characterized by the arrangement of the lighting circuit 21 and the wireless communication unit 3 within the case 20. In the light source unit A1 of Modified Example 7, a rectangular void 250 is formed in the center of the printed circuit board 25 of the lighting circuit 21, and the printed circuit board 32 of the wireless circuit unit 30 is arranged within this void 250 (see Figure 16).

[0085] The light source unit A1 in modification 7 can make effective use of the space inside the case 20, thereby reducing the size of the case 20.

[0086] (3-8) Other variations The printed circuit board 25 of the lighting circuit 21 and the printed circuit board 32 of the wireless communication unit 3 may be housed in the case 20 at a distance from each other in the height direction (up and down direction) of the case 20 (see Figure 17A). In this case, it is preferable that the printed circuit board 32 of the wireless communication unit 3 be positioned closer to the opening 204 of the case 20 than the printed circuit board 25 of the lighting circuit 21 in the height direction of the case 20. By positioning the wireless communication unit 3 (especially the antenna unit 31) near the opening 204 of the case 20, attenuation of the wireless signal can be reduced. However, the printed circuit board 25 of the lighting circuit 21 may also be positioned near the opening 204 of the case 20 (see Figure 17B). In this case, the length of the conductor (e.g., electric wire) electrically connecting the lighting circuit 21 and the wireless communication unit 3 can be shortened, improving noise immunity.

[0087] Furthermore, the printed circuit board 25 of the lighting circuit 21 may be housed in the case 20 such that it completely overlaps with the printed circuit board 32 of the wireless communication unit 3 when viewed from the height direction of the case 20 (the direction opposite to the second surface 40B of the bottom plate 40 of the mounting member 4) (see Figure 17C). By housing the printed circuit board 25 of the lighting circuit 21 in the case 20 in such a way that the entire printed circuit board 32 of the wireless communication unit 3 overlaps with the printed circuit board 25 of the lighting circuit 21, the lengthwise dimension of the case 20 can be shortened. However, the printed circuit board 25 of the lighting circuit 21 may be housed in the case 20 such that it overlaps with a part of the printed circuit board 32 of the wireless communication unit 3 (see Figure 17D). The antenna unit 31 may be formed separately from the wireless circuit unit 30, or, as in the modified example 1, the antenna unit 31 may be provided on the printed circuit board 32 of the wireless circuit unit 30.

[0088] The connecting member that connects the lighting circuit 21 and the wireless circuit section 30 is not limited to the signal connector 5, but may be a harness cable with multiple wires bundled together, etc. Also, the signal connector 5 is not limited to a structure that can be inserted and removed from both sides of the surface of the printed circuit boards 25 and 32, but may be a structure that can be inserted and removed from the thickness direction of the printed circuit boards 25 and 32.

[0089] Furthermore, each printed circuit board 25, 32 may be fixed to the case 20 by being screwed to, for example, multiple bosses protruding from the bottom wall 200 of the case 20.

[0090] Furthermore, the wireless communication unit 3 may receive and transmit wireless signals containing not only information related to the lighting control of the LED module 1, but also other information.

[0091] For example, the wireless communication unit 3 may transmit a wireless signal containing information regarding the usage status of the light source unit A1. This information regarding the usage status of the light source unit A1 may include, for example, the time (date) when use began, the cumulative lighting time, the occurrence of an abnormality in the power supply unit 2 or LED module 1, the diagnosis result of the lifespan of the power supply unit 2 or LED module 1, the time period during which it was lit, and the power consumption. Alternatively, the wireless communication unit 3 may transmit a wireless signal containing detection information from sensors provided on the light source unit A1 or the fixture body 9. This sensor detection information may include, for example, detection information of the presence or absence of a person by a motion sensor, or detection information of brightness (illuminance) by a brightness sensor. Alternatively, the wireless communication unit 3 may transmit a wireless signal containing identification information for the light source unit A1. This identification information may include the manufacturing lot number of the light source unit A1, the model number corresponding to the type of light source unit A1, and so on.

[0092] The various types of information mentioned above (information other than information related to lighting control) may be used to link lighting fixture B1 with other devices. Other devices linked with lighting fixture B1 include, for example, television receivers, audio equipment such as wireless speakers or smart speakers, air conditioning and air quality equipment such as air conditioners and air purifiers, security equipment, and disaster prevention equipment.

The wireless communication unit (3) has an antenna unit (31) that emits electromagnetic waves into space or receives electromagnetic waves from space, and a wireless circuit unit (30) that transmits or receives at least one of wireless signals using electromagnetic waves as a medium via the antenna unit (31). The mounting member (4) has a light source mounted on a first surface (40A) and a power supply device (2) mounted on a second surface (40B) opposite to the first surface (40A). The power supply device (2) has a lighting circuit (21) that controls lighting power, and a case (20) that houses the lighting circuit (21) and the wireless circuit unit (30). At least a part of the antenna unit (31) is outside the case (20).

[0094] In the first embodiment of the lighting device, the lighting circuit (21) and the wireless circuit section (30) are housed in the case (20) of the power supply unit (2). Therefore, the installation of the lighting circuit (21) and the wireless circuit section (30) to the mounting member (4) is completed by attaching the case (20) to the mounting member (4). As a result, the lighting device according to the first embodiment can improve the workability of the assembly work compared to the conventional example. Moreover, in the lighting device according to the first embodiment, at least a part of the antenna section (31) is outside the case (20), so the attenuation of electromagnetic waves emitted by the antenna section (31) into space or electromagnetic waves received by the antenna section (31) from space can be suppressed compared to the case where the entire antenna section (31) is inside the case (20).

[0095] A lighting device according to a second aspect of this disclosure can be realized by combining it with the first aspect. In the lighting device according to the second aspect, it is preferable that the entire antenna portion (31) is outside the case (20).

In the lighting device according to the third aspect, it is preferable that a part of the antenna portion (31) that is outside the case (20) protrudes from inside the case (20) to outside the case (20).

[0098] In the third embodiment of the lighting device, a part of the antenna section (31) protrudes from inside the case (20) to outside the case (20), making it easier to secure installation space for the antenna section (31).

[0100] In the fourth embodiment of the lighting device, since the antenna portion (31) is located in front of the first surface (40A) of the mounting member (4), attenuation of radio waves emitted by the antenna portion (31) into space or received from space can be suppressed, thereby improving the sensitivity of transmitting or receiving wireless signals.

The antenna portion (31) preferably includes a conductor formed on the surface or back surface of the mounting substrate.

[0102] In the fifth embodiment of the lighting device, the antenna portion (31) is formed integrally with the light source, thereby enabling miniaturization of the antenna portion (31).

[0104] In the sixth embodiment, the lighting device, when attached to the fixture body (9), can have the power terminal section (22) positioned near the terminal block (902) attached to the fixture body (9). Therefore, the lighting device in the sixth embodiment can shorten the wiring (power cable 903) connecting the power terminal section (22) and the lighting circuit (21).

[0105] A lighting device according to the seventh aspect of this disclosure can be realized in combination with any of the first to fifth aspects.
