[0011] The power supply and lighting devices according to Embodiments 1 and 2 will be described below with reference to the drawings. The figures described in each embodiment below are schematic diagrams, and the ratios of the size and thickness of each component do not necessarily reflect the actual dimensional ratios. Furthermore, the configurations described in each embodiment below are merely examples of this disclosure. This disclosure is not limited to the embodiments below, and various modifications are possible depending on the design, etc., as long as the effects of this disclosure can be achieved.

[0012] Furthermore, in the following explanation, unless otherwise specified, the first direction D1, second direction D2, and third direction D3 indicated by arrows in the drawings are defined as the front-to-back, up-and-down, and left-to-right directions of the power supply units A1 and A2 and the lighting device B1. However, the front-to-back, up-and-down, and left-to-right directions are used for convenience to aid in understanding the explanation of each embodiment and do not define the direction in which the power supply units A1 and A2 and the lighting device B1 are used. Also, the arrows indicating "D1," "D2," and "D3" in the drawings are for illustrative purposes only and do not represent any actual physical object.

[0013] (Embodiment 1) The power supply unit A1 and lighting device B1 according to Embodiment 1 will be described below with reference to Figures 1 to 10.

[0014] (1)Power supply device The power supply device A1 shown in FIG. 1 is a power supply device for lighting. Further, the power supply device A1 is a power supply device having a wireless communication function.

[0015] The power supply device A1 includes, for example, a power supply board 1, a wireless communication device 2, and a housing 4 (see FIGS. 2 and 6). In FIG. 1, the illustration of the housing 4 is omitted for the sake of understanding the description of the embodiment. Further, in FIGS. 2 to 4, the illustration of the housing 4 is schematically represented by a two-dot chain line for the sake of understanding the description of the embodiment.

[0016] (1.1) Power supply board As shown in FIG. 1 for example, the power supply board 1 includes a power supply circuit 10 and a board 100.

[0017] The power supply circuit 10 supplies power to a load. The load is, for example, a light source (in the example of FIG. 7, an LED module 50). The LED module 50 includes, for example, a plurality of LEDs. The plurality of LEDs are, for example, electrically connected in series. The details of the LED module 50 will be described later. Also, the number of LED modules 50 may be one or more.

[0018] As shown in FIG. 1 for example, the power supply circuit 10 includes a plurality of electronic components 11, a power supply connector 12, and an output connector 16. The plurality of electronic components 11 include, for example, resistors, capacitors, transformers, IC (Integrated Circuit) chips, and the like. The power supply connector 12 is electrically connected to an external power supply P1 (see FIG. 7) via, for example, a power cable. The external power supply P1 is, for example, a commercial power system. The output connector 16 is electrically connected to the LED module 50 via, for example, a connection cable. Note that the number of electronic components 11 in FIG. 1 does not illustrate the actual number of electronic components 11.

[0019] The board 100 arranges the power supply circuit 10. For example, the board 100 arranges a plurality of electronic components 11, a power supply connector 12, and an output connector 16. The board 100 is, for example, a printed wiring board. The board 100 is, for example, plate-shaped (for example, rectangular plate-shaped).

[0020] In this embodiment, multiple electronic components 11, a power connector 12, and an output connector 16 are arranged on one surface (top surface) of the substrate 100. The power connector 12 is located on one surface 1a of the power supply substrate 1 at the first end (front end) in the front-to-back direction (first direction D1) of the power supply substrate 1. The output connector 16 is located on one surface 1a of the power supply substrate 1 at the second end (rear end) in the front-to-back direction of the power supply substrate 1.

[0021] Furthermore, in this embodiment, other electronic components besides the multiple electronic components 11 are arranged on the side (bottom surface) of the power supply board 1 opposite to one side 1a. These other electronic components include, for example, resistors, capacitors, IC chips, and the like.

[0022] The power supply board 1, for example, uses the power supply circuit 10 and the conductors (copper foil) of the board 100 to realize the functions of the power conversion circuit 13, constant current circuit 14, and control circuit 15 shown in Figure 7.

[0023] The power conversion circuit 13 is electrically connected to the power connector 12. The power conversion circuit 13 is also electrically connected to the constant current circuit 14 and the control circuit 15. The power conversion circuit 13 converts AC power input from the external power supply P1 via the power connector 12 into DC power, for example, according to control from the control circuit 15. The power conversion circuit 13 also outputs the DC power to the constant current circuit 14. The power conversion circuit 13 includes, for example, a rectifier circuit (e.g., a diode bridge) and a boost chopper circuit (power factor correction circuit).

[0024] The power conversion circuit 13 may convert the DC power to a smaller power and output the smaller power to the control circuit 15. In this case, the power conversion circuit 13 may further include, for example, a step-down circuit. The power conversion circuit 13 may also output the smaller power to the wireless communication device 2.

[0025] The constant current circuit 14 is electrically connected to the LED module 50. The constant current circuit 14 includes, for example, a step-down chopper circuit (buck converter). The constant current circuit 14 converts the DC power from the power conversion circuit 13 to a predetermined DC power, for example, according to control from the control circuit 15. The constant current circuit 14 also outputs the predetermined DC power to the LED module 50 according to control from the control circuit 15. More specifically, the constant current circuit 14 outputs the predetermined DC power to the LED module 50 according to control from the control circuit 15 so that the current value of the DC current output to the LED module 50 becomes a target value.

[0026] Therefore, the constant current circuit 14 lights up the LED module 50 according to the control from the control circuit 15 (for example, lighting control). The constant current circuit 14 also dims the LED module 50 according to the control from the control circuit 15 (for example, dimming control).

[0027] The control circuit 15 is implemented, for example, by a computer system having one or more processors and one or more memories. In other words, the functions of the control circuit 15 are realized by one or more processors executing a program stored in memory. The program may be pre-stored in memory, provided via a telecommunication line such as the Internet, or provided on a non-temporary recording medium such as a memory card.

[0028] The control circuit 15 controls the power conversion circuit 13 and the constant current circuit 14. For example, the control circuit 15 controls the power conversion circuit 13 so that it converts the AC power to the DC power. The control circuit 15 also controls the constant current circuit 14 so that it converts the DC power to a predetermined DC power. Furthermore, the control circuit 15 controls the constant current circuit 14 so that the current value of the DC current output from the constant current circuit 14 to the LED module 50 becomes the target value.

[0029] The control circuit 15 is electrically connected to the wireless communication device 2 via the connection part 3 on the power supply board 1, which will be described later. The control circuit 15 controls the constant current circuit 14 in accordance with the signal received by the wireless communication device 2, for example. Specifically, the control circuit 15 changes the target value of the DC current output from the constant current circuit 14 to the LED module 50 in accordance with the signal received by the wireless communication device 2. The control circuit 15 also controls the wireless communication device 2 to transmit a signal containing control information (e.g., dimming information) to another lighting device using the wireless communication device 2. In other words, the wireless communication device 2 transmits a signal containing control information from the control circuit 15 to another lighting device.

[0030] As shown in Figure 1, the power supply board 1 has a connection part 3. The connection part 3 is connected to a connection part 27 (see Figure 5) of the wireless communication device 2, which will be described later. More specifically, the connection part 3 is electrically connected to the connection part 27 of the wireless communication device 2 when a part of the wireless communication device 2 is inserted into the insertion hole 300 (see Figure 5) of the connection part 3, which will be described later.

[0031] The connection portion 3 is located on one surface 1a of the power supply board 1, for example, as shown in Figure 4. The connection portion 3 is located on one surface 1a of the power supply board 1, for example, at one end (front end) in the front-to-back direction (first direction D1) of the power supply board 1, and at one end (right end) in the left-to-right direction (third direction D3) of the power supply board 1.

[0032] The connection part 3, as shown in Figure 5 for example, has a main body 30, a plurality of contacts 31 (four in the example of Figure 5), a plurality of terminal pieces 32 (four in the example of Figure 5), and a plurality of leg pieces 33.

[0033] The main body 30 is, for example, box-shaped (for example, rectangular box-shaped). The material of the main body 30 is, for example, an electrically insulating material (for example, resin). The main body 30 has an insertion hole 300 into which the above part of the wireless communication device 2 is inserted, and a support (not shown) that supports a plurality of contacts 31.

[0034] The insertion hole 300 is configured so that a portion of the wireless communication device 2 can be inserted from a direction perpendicular to one surface 1a (see Figure 1) of the power supply board 1 (second direction D2). The insertion hole 300 is provided, for example, across the upper wall 30a of the main body 30 and one of the four side walls 30b. In other words, the insertion hole 300 is provided in the main body 30 such that a portion of the upper wall 30a and the side wall 30b of the main body 30 is open.

[0035] The support is located within the main body 30. The support is, for example, rectangular in shape. The material of the support is an electrically insulating material. The support may be, for example, continuously integrated with the main body 30, or it may be configured as a part of the main body 30 (for example, the bottom wall 30c of the main body 30).

[0036] Each of the multiple contacts 31 is, for example, rectangular (e.g., elongated rectangle). The material of each of the multiple contacts 31 is, for example, metal (e.g., copper). The multiple contacts 31 are arranged in a line with spacing between them along one direction (first direction D1) parallel to one surface 1a of the power supply board 1.

[0037] The multiple contacts 31 are arranged within the main body 30, for example, with the central portion of each of the multiple contacts 31 supported by a support. Alternatively, the multiple contacts 31 are arranged within the main body 30, for example, with the first end (lower end) of each of the multiple contacts 31 electrically connected one-to-one with each of the multiple terminal pieces 32. Alternatively, the multiple contacts 31 are arranged within the main body 30, for example, with the second end (upper end) of each of the multiple contacts 31 exposed to the insertion hole 300 of the main body 30.

[0038] In other words, the multiple contacts 31 are arranged within the main body 30 such that the upper end of each of the multiple contacts 31 contacts a connection portion 27 (in this embodiment, a plurality of conductors 22 described later) provided on the above part of the wireless communication device 2 inserted into the insertion hole 300 of the main body 30, thereby making an electrical connection. Here, the upper end of each of the multiple contacts 31 may be bent in a U-shape or V-shape in a side view, for example. This allows the power supply A1 to improve the contact pressure of the multiple contacts 31 with respect to the connection portion 27, thereby improving the reliability of the electrical connection between the multiple contacts 31 and the connection portion 27.

[0039] Each of the multiple terminal pieces 32 is, for example, rectangular (e.g., elongated rectangle). The material of each of the multiple terminal pieces 32 is, for example, metal (e.g., copper). The multiple terminal pieces 32 are arranged in a line with spacing between them along one direction (first direction D1) parallel to one surface 1a of the power supply board 1. The multiple terminal pieces 32 also penetrate the bottom wall 30c of the main body 30 and protrude along the vertical direction (second direction D2) of the main body 30.

[0040] Multiple terminal pieces 32 are connected one-to-one with multiple contacts 31. In short, multiple terminal pieces 32 are electrically connected one-to-one with multiple contacts 31. Furthermore, multiple terminal pieces 32 are electrically connected to the conductor (copper foil) of the substrate 100 (see Figure 1) on the power supply board 1. Specifically, multiple terminal pieces 32 are electrically connected to the conductor (copper foil) of the substrate 100 through multiple through-holes that are pre-provided in the substrate 100.

[0041] Multiple leg pieces 33 protrude from the bottom wall 30c of the main body 30 along the vertical direction of the main body 30. The material of each of the multiple leg pieces 33 is, for example, an electrically insulating material. Furthermore, the multiple leg pieces 33 are integrally formed with, for example, the bottom wall 30c of the main body 30. The multiple leg pieces 33 are inserted one-to-one into multiple holes (fixing holes) pre-provided in the substrate 100. That is, the connection part 3 is fixed to the substrate 100 via the multiple leg pieces 33.

[0042] Here, it is preferable that the outer surface of the main body 30 of the connection part 3 and the outer surface of each of the multiple leg pieces 33 are covered with a metal film. In this case, the metal film is electrically connected to the ground of the substrate 100 on the power supply board 1. As a result, the power supply A1 can reduce the degradation of the communication performance (wireless communication performance) of the wireless communication device 2 due to external noise, for example.

[0043] (1.2) Wireless communication devices Wireless communication device 2 performs wireless communication using electromagnetic waves as a medium. Furthermore, wireless communication device 2 performs wireless communication in accordance with wireless communication standards. For example, wireless communication device 2 performs wireless communication in accordance with the Bluetooth® standard. More specifically, wireless communication device 2 performs wireless communication in accordance with the BLE (Bluetooth® Low Energy) standard. The medium for wireless communication is preferably electromagnetic waves such as radio waves, infrared rays, or visible light, with radio waves being particularly desirable.

[0044] The wireless communication device 2 receives wireless signals transmitted from, for example, a communication device such as a remote controller or a smartphone. The power supply board 1 shown in Figure 7 lights up the LED module 50 according to the information (for example, control information) contained in the wireless signal received by the wireless communication device 2. The power supply board 1 also dims the LED module 50 according to the control information contained in the wireless signal received by the wireless communication device 2.

[0045] The wireless communication device 2 is plate-shaped, as shown in Figure 5, for example. The wireless communication device 2 includes, for example, a first module 20 and a second module 21.

[0046] The first module 20 includes, for example, a plurality of first electronic components 23, a plurality of second electronic components 25 (see Figure 3), a first substrate 200, and an antenna 24. The first module 20 is the part of the wireless communication device 2 that performs wireless communication using electromagnetic waves as a medium.

[0047] The multiple first electronic components 23 include, for example, resistors, capacitors, IC chips, etc. The multiple second electronic components 25 include, for example, resistors, capacitors, IC chips, etc.

[0048] The first substrate 200 arranges, for example, a plurality of first electronic components 23, a plurality of second electronic components 25, and an antenna 24. The first substrate 200 is, for example, a printed circuit board. The first substrate 200 is, for example, a plate (for example, a rectangular plate). The plurality of first electronic components 23 are arranged on the first surface (hereinafter referred to as the "front surface") 200a of the first substrate 200. The plurality of second electronic components 25 are arranged on the second surface (hereinafter referred to as the "back surface") 200b (see Figure 3) of the first substrate 200. The back surface 200b of the first substrate 200 is a surface parallel to the front surface 200a of the first substrate 200.

[0049] The wireless communication device 2 shown in Figure 5 realizes the function of the wireless communication circuit 26 using, for example, a plurality of first electronic components 23, a plurality of second electronic components 25 (see Figure 3), and a conductor (copper foil) of the first substrate 200. The wireless communication circuit 26 is configured to perform wireless communication compliant with the BLE standard, for example. The wireless communication circuit 26 is also configured to send and receive wireless signals via the antenna 24. The wireless communication device 2 operates with less power than the DC power supplied from the power conversion circuit 13 (see Figure 7) of the power supply board 1 via the connection part 3.

[0050] Antenna 24 is a so-called pattern antenna, for example, made of a conductor (copper foil) formed on the surface 200a of the first substrate 200. Here, since antenna 24 is formed on the surface 200a of the first substrate 200 of the wireless communication device 2, it can transmit electromagnetic waves more strongly in the thickness direction (third direction D3) of the first substrate 200 and receive electromagnetic waves arriving from the thickness direction of the first substrate 200 more strongly. Therefore, the wireless communication device 2 can improve the transmission and reception performance of electromagnetic waves in the thickness direction of the first substrate 200. In other words, the power supply A1 can improve the communication performance of the wireless communication device 2. Note that antenna 24 is not limited to a pattern antenna.

[0051] The second module section 21 includes, for example, a second circuit board 210 and a connection section 27. In the wireless communication device 2, the second module section 21 is the part that is inserted into the insertion hole 300 of the main body section 30 of the connection section 3 of the power supply board 1. In short, the second module section 21 is the above-mentioned part of the wireless communication device 2.

[0052] The second substrate 210 has a connection portion 27. The second substrate 210 is, for example, a printed circuit board. The second substrate 210 is, for example, a plate (for example, a rectangular plate). The area of ​​the second substrate 210 is smaller than the area of ​​the first substrate 200. The second substrate 210 is connected to the first substrate 200. For example, the second substrate 210 is connected to the first substrate 200 such that one surface 210a of the second substrate 210 and the surface 200a of the first substrate 200 are flush. In this embodiment, the second substrate 210 is located at the left end of the first substrate 200, for example, as shown in Figure 5. In other words, the second module portion 21 is located at the left end of the first module portion 20.

[0053] The connection part 27 is a connection part for electrically connecting to the power supply board 1. More specifically, the connection part 27 is a connection part for electrically connecting to the connection part 3 of the power supply board 1. In the following, to aid in understanding the description of the embodiment, the connection part 27 of the wireless communication device 2 will be referred to as the "first connection part 27," and the connection part 3 of the power supply board 1 will be referred to as the "second connection part 3."

[0054] The first connection section 27 includes, for example, a plurality of conductors 22 (four in the example shown in Figure 5). The plurality of conductors 22 are configured to be electrically connectable to the second connection section 3 of the power supply board 1. More specifically, the plurality of conductors 22 are configured to be electrically connectable one-to-one to a plurality of contacts 31 in the second connection section 3 of the power supply board 1. Each of the plurality of conductors 22 is, for example, rectangular (e.g., elongated rectangle). The material of each of the plurality of conductors 22 is, for example, metal (e.g., copper).

[0055] Multiple conductors 22 are arranged on one surface 210a of the second substrate 210. The multiple conductors 22 are arranged in a line with spacing between them along a direction perpendicular to the surface 210a of the second substrate 210 (third direction D3) and a direction orthogonal to it (first direction D1). In other words, the multiple conductors 22 are arranged in a line with spacing between them along a direction parallel to the surface 1a of the power supply board 1 (first direction D1). The multiple conductors 22 are electrically connected to the conductors (copper foil) of the second substrate 210 of the wireless communication device 2. Furthermore, the multiple conductors 22 are electrically connected to the conductors (copper foil) of the first substrate 200 of the wireless communication device 2 via the conductors of the second substrate 210. That is, the multiple conductors 22 are electrically connected to the wireless communication circuit 26. Note that the conductors of the second substrate 210 refer to the conductors (copper foil) of the inner layer of the second substrate 210.

[0056] The wireless communication device 2 is electrically connected to the power supply board 1 when the second module 21 of the wireless communication device 2 is inserted into the insertion hole 300 of the main body 30 of the second connection part 3 of the power supply board 1 from one direction (up) in the vertical direction (second direction D2) (upwards) downwards, and then the first connection part 27 (multiple conductors 22) of the second module 21 makes contact with the second connection part 3 (multiple contacts 31) of the power supply board 1. In addition, the wireless communication device 2 is mechanically connected to the power supply board 1 when the second module 21 of the wireless communication device 2 is sandwiched between the multiple contacts 31 and the main body 30 of the second connection part 3.

[0057] Therefore, the second module 21 of the wireless communication device 2 is directly connected to the second connection 3 of the power supply board 1 without using wiring such as a harness. In other words, the first connection 27 of the wireless communication module 2 is directly connected to the second connection 3 of the power supply board 1 without using wiring such as a harness.

[0058] In the power supply unit A1 of this embodiment, as shown in Figure 4, the second connection part 3 of the power supply board 1 and the wireless communication device 2 are arranged on one surface 1a of the power supply board 1.

[0059] (1.3) Enclosure The housing 4 shown in Figure 6 houses the power supply board 1 and the wireless communication device 2. The housing 4 is box-shaped (for example, rectangular box-shaped). The material of the housing 4 is, for example, metal (for example, aluminum alloy). One end (front end) of the housing 4 in the front-to-back direction (first direction D1) is provided with a hole (window hole) that exposes the power connector 12 of the power supply board 1. Note that the power supply board 1 is not shown in Figure 6.

[0060] The power supply board 1 shown in Figure 1 is housed within the housing 4 (see Figure 6) such that, for example, one side 1a of the power supply board 1 faces the first direction (upwards) in the vertical direction (second direction D2) of the housing 4. In short, the power supply board 1 is positioned within the housing 4 such that one side 1a of the power supply board 1 faces upwards towards the housing 4.

[0061] In addition, the power supply board 1 is housed in the housing 4 such that one side 1a of the power supply board 1 faces upwards to the housing 4, but it may also be housed in the housing 4 such that one side 1a of the power supply board 1 faces a second direction (downwards) in the vertical direction of the housing 4. However, in this case, it is preferable that the power supply A1 includes a member (fixing member) for maintaining the connection between the first connection part 27 of the wireless communication device 2 and the second connection part 3 of the power supply board 1, in order to prevent the connection between the first connection part 27 and the second connection part 3 from being released due to the weight of the wireless communication device 2.

[0062] The housing 4 has, for example, a plurality (e.g., two) of openings 40. The plurality of openings 40 include a first opening 40a and a second opening. Note that in Figure 6, only one of the two openings 40 (e.g., the first opening 40a) is visible, and the remaining opening 40 (e.g., the second opening) is not visible.

[0063] Each of the multiple openings 40 allows electromagnetic waves of wireless communication from the wireless communication device 2 to pass through. Each of the multiple openings 40 is, for example, a hole (opening) that allows electromagnetic waves of wireless communication from the wireless communication device 2 to pass through.

[0064] The first opening 40a is located in the housing 4 in the thickness direction (third direction D3) of the wireless communication device 2. For example, the first opening 40a is located in the housing 4 on the first side wall (left side wall) 42 in the left-right direction (third direction D3) of the housing 4. Also, the first opening 40a is located on the left side wall 42 of the housing 4, facing the surface 200a of the first substrate 200 of the wireless communication device 2.

[0065] Furthermore, the first opening 40a is positioned parallel to the surface 200a of the first substrate 200 on the left side wall 42 of the housing 4. In other words, the first opening 40a is positioned along one direction (first direction D1) parallel to one surface 1a of the power supply board 1 on the left side wall 42 of the housing 4. In short, the first opening 40a is positioned along the front-to-back direction (first direction D1) of the housing 4 on the left side wall 42 of the housing 4.

[0066] The first opening 40a is, for example, rectangular (e.g., elongated rectangle). The first opening 40a is provided on the left side wall 42 of the housing 4, extending from the front end 42a to the rear end 42b in the front-to-rear direction (first direction D1) of the housing 4, along the front-to-rear direction of the housing 4. The first opening 40a is a slot antenna corresponding to the frequency band (e.g., 2.4 GHz band) of the wireless communication by the wireless communication device 2. The frequency band of the wireless communication by the wireless communication device 2 corresponds to the wireless communication standard adopted by the wireless communication device 2. It is preferable that the first opening 40a is a slot antenna.

[0067] The front-to-back dimension (first opening dimension) W1 of the housing 4 at the first opening 40a is preferably at least one-quarter of the wavelength of the electromagnetic wave of the wireless communication by the wireless communication device 2, and preferably at least two-thirds of the wavelength of the electromagnetic wave, and most preferably at least half the wavelength of the electromagnetic wave. For example, when the wireless communication device 2 uses electromagnetic waves in the 2.4 GHz band as a medium, the wavelength of this electromagnetic wave is approximately 120 mm, so the first opening dimension W1 of the first opening 40a is preferably in the range of 30 mm to 60 mm. Furthermore, the vertical dimension (second opening dimension) W2 of the housing 4 at the first opening 40a is preferably in the range of 1 mm to 5 mm.

[0068] The second opening is located in the housing 4 in the thickness direction of the wireless communication device 2. For example, the second opening is located in the housing 4 on the second side wall (right side wall) in the left-right direction of the housing 4. Also, the second opening is located on the right side wall of the housing 4, opposite the back surface 200b (see Figure 3) of the first substrate 200 of the wireless communication device 2.

[0069] Furthermore, the second opening is located on the right side wall of the housing 4, parallel to the back surface 200b of the first circuit board 200. In other words, the second opening is located on the right side wall of the housing 4, along the aforementioned one direction parallel to one surface 1a of the power supply board 1. In short, the second opening is located on the right side wall of the housing 4, along the front-to-back direction of the housing 4. Note that the second opening has the same configuration as the first opening 40a, so a detailed explanation is omitted.

[0070] In this embodiment, it is preferable that one of the multiple openings 40 (the first opening 40a) is positioned in the housing 4 opposite the antenna 24 of the wireless communication device 2. This allows the power supply A1 to improve, for example, the transmission and reception characteristics of wireless signals, thereby improving the communication performance of the wireless communication device 2.

[0071] As shown in Figure 1, the power supply board 1 and the wireless communication device 2 are housed in the housing 4 with the first connection portion 27 of the wireless communication device 2 (see Figure 5) electrically connected to the second connection portion 3 of the power supply board 1 from a direction perpendicular to one surface 1a of the power supply board 1 (second direction D2). More specifically, the power supply board 1 and the wireless communication device 2 are housed in the housing 4 with the first connection portion 27 of the wireless communication device 2 in contact with the second connection portion 3 of the power supply board 1 from a direction perpendicular to one surface 1a of the power supply board 1.

[0072] Furthermore, the wireless communication device 2 is housed within the housing 4 with the second module section 21 electrically connected to the second connection section 3 of the power supply board 1 from a direction perpendicular to one surface 1a of the power supply board 1. In other words, the wireless communication device 2 is housed within the housing 4 with the thickness direction (third direction D3) of the second module section 21 and the thickness direction (second direction D2) of the board 100 on the power supply board 1 intersecting. That is, the wireless communication module 2 is positioned perpendicular to one surface 1a of the power supply board 1.

[0073] Power supply unit A1 has a function to dim the LED module 50 (see Figure 7). Here, power supply unit A1 may be configured to dim the LED module 50 when the wireless communication device 2 is electrically connected to the power supply board 1. Alternatively, power supply unit A1 may be configured not to dim the LED module 50 when the wireless communication device 2 is not electrically connected to the power supply board 1. In other words, power supply unit A1 may be configured to dim the LED module 50 based on the connection status (whether or not a connection is made) between the wireless communication device 2 and the power supply board 1. This allows power supply unit A1 to switch between dimming and not dimming the LED module 50 depending on whether or not the wireless communication device 2 is connected to the power supply board 1.

[0074] (2) Lighting devices The lighting device B1 comprises a light source unit 5 and a fixture body 6, as shown in Figures 7 and 8, for example. The light source unit 5 includes a power supply A1 and an LED module 50 (light source). The LED module 50 is configured to light up with power supplied from the power supply A1 (the DC power mentioned above). The light source unit 5 is configured to be detachably attached to the fixture body 6. The fixture body 6 supports the light source unit 5. The fixture body 6 is also mounted directly to the ceiling, for example.

[0075] (2.1) Main body of the device The main body of the device 6, as shown in Figures 9 and 10, for example, comprises a long, box-shaped housing section 60 with an open bottom, a pair of reflectors 61 projecting diagonally upward from the open edges on both sides of the housing section 60 along the left-right direction (third direction D3), and a pair of end plates 62 provided at both ends of the housing section 60 and the pair of reflectors 61 in the front-rear direction (first direction D1). The housing section 60 and the pair of reflectors 61 are integrally formed, for example, by punching and bending a metal plate.

[0076] The fixture body 6 is directly attached to the ceiling by, for example, inserting suspension bolts (not shown) through at least two of the multiple mounting holes 63 provided on the bottom (top) surface of the housing 60, and tightening nuts (not shown) onto these suspension bolts. In addition, a power cable is inserted through one of the multiple power supply holes 64 provided on the bottom surface of the housing 60.

[0077] A terminal block 65 is mounted on the bottom of the housing section 60 (see Figure 9). The terminal block 65 is electrically connected to the power cable (first power cable). The terminal block 65 is also electrically connected to the second power cable. The end of the second power cable is provided with a connector (not shown) that can be electrically connected to the power connector 12 of the power supply unit A1.

[0078] Therefore, the first power cable inserted through one of the power holes 64 of the fixture body 6 is electrically connected to the terminal block 65, and is electrically connected to the power supply unit A1 via the terminal block 65, the second power cable, the connector and the power connector 12 (see Figure 6).

[0079] The housing section 60 is provided with a pair of hooking holes (not shown) and a pair of hooking parts 601 at both ends in the front-rear direction (first direction D1) of the housing section 60 (see Figure 9). The pair of hooking holes are located on the first side wall (left side wall) in the left-right direction of the housing section 60. The pair of hooking parts 601 are located on the second side wall (right side wall) in the left-right direction of the housing section 60 (see Figure 9).

[0080] (2.2) Light source unit The light source unit 5 includes, for example, an LED module 50, a mounting member 51, a cover 52, and a power supply A1, as shown in Figure 9.

[0081] The LED module 50 includes, for example, a plurality of substrates 500 (two in the example shown in Figure 9) and a plurality of LEDs arranged on one side (bottom surface) of each of the plurality of substrates 500. Each of the plurality of LEDs is, for example, a packaged white LED for illumination. The light-emitting element arranged on the bottom surface of each of the plurality of substrates 500 is not limited to LEDs, but may be, for example, an organic electroluminescent element, a semiconductor laser element, etc. Also, the number of plurality of substrates 500 is not limited to two, but may be three or more, or even just one.

[0082] Each of the multiple circuit boards 500 is, for example, a long rectangle. The multiple LEDs are arranged on the underside of the circuit boards 500, in the center in the left-right direction (third direction D3) of the circuit board 500. The multiple LEDs are also arranged in a row on the underside of the circuit boards 500, spaced apart along the front-to-back direction (first direction D1) of the circuit board 500. The multiple LEDs are electrically connected in series by conductors (printed wiring) formed on the underside of the circuit boards 500. The multiple circuit boards 500 are electrically connected via two sets of connectors 502.

[0083] The mounting member 51 is constructed in the shape of a long rectangular trough using a metal plate, as shown in Figures 9 and 10, for example. The mounting member 51 has a long rectangular base plate 510 and a pair of side plates 511 that rise upward from both ends of the base plate 510 along the left-right direction (third direction D3).

[0084] The LED module 50 is attached to the underside of the base plate 510 by a plurality of claws 512 cut out from the base plate 510, as shown in Figure 9, for example.

[0085] As shown in Figures 9 and 10, the mounting member 51 is provided with hook fittings 513 at each end of the mounting member 51 in the front-to-back direction (first direction D1), and protruding from the first end (left end) in the left-to-right direction (third direction D3). Also, as shown in Figure 10, the mounting member 51 is provided with hook springs 514 at each of the second ends (right end) in the left-to-right direction at both ends of the mounting member 51 in the front-to-back direction. The pair of hook fittings 513 and the pair of hook springs 514 play a role in holding the light source unit 5 to the fixture body 6.

[0086] As shown in Figure 10, the power supply unit A1 is attached to the bottom plate 510 of the mounting member 51. The power supply unit A1 is attached to the bottom plate 510 of the mounting member 51 by screwing the mounting plate 44 (see Figure 6) provided on the housing 4 to the bottom plate 510.

[0087] The cover 52, as shown in Figures 9 and 10, for example, has a cover body 520, a pair of cover ends 521, a pair of protruding walls 522, and a pair of extensions 523.

[0088] The cover body 520 is, for example, a long semi-cylindrical shape. A pair of cover ends 521 are attached to both ends of the cover body 520 in the front-rear direction (first direction D1). In other words, both ends of the cover body 520 in the front-rear direction are closed by the cover ends 521. A pair of extensions 523 project inward from both ends of the cover body 520 in the left-right direction (third direction D3) along the front-rear direction (first direction D1). A pair of protruding walls 522 project upward from the pair of extensions 523 along the front-rear direction of the cover body 520, as shown in Figure 10. Note that the shape of the cover body 520 is not limited to a long semi-cylindrical shape, but may be any shape, such as a rectangular tube shape.

[0089] The cover body 520, the pair of protruding walls 522, and the pair of extensions 523 are integrally constructed from a translucent material (e.g., acrylic resin, polycarbonate resin, etc.). The pair of cover ends 521 are constructed in a semi-circular disc shape from a translucent material. Preferably, the material of the cover body 520, the pair of protruding walls 522, and the pair of extensions 523 is the same as the material of the pair of cover ends 521.

[0090] The cover 52 is attached to the mounting member 51 by housing the mounting member 51 between a pair of protruding walls 522, and the upper ends of the pair of protruding walls 522 being hooked onto the tips (upper ends) of the pair of side plates 511 of the mounting member 51 (see Figure 10).

[0091] The light source unit 5 is temporarily suspended from the fixture body 6 by hooking the ends of a pair of hook fittings 513 into a pair of hook holes in the housing section 60. With the light source unit 5 temporarily suspended, wiring work is performed, such as connecting the connector of the second power cable to the power connector 12 of the power supply unit A1. After the wiring work is completed, the light source unit 5 is held in place by the spring force of the pair of hook springs 514 by pressing the light source unit 5 against the fixture body 6 from below upward so as to house the power supply unit A1 in the housing section 60 (see Figure 8).

[0092] Lighting device B1 is installed, for example, on the ceiling of an office. Multiple lighting devices B1 are installed on the office ceiling, for example, arranged vertically and horizontally with spacing between them. These multiple lighting devices B1 installed on the office ceiling can communicate wirelessly with each other. That is, when the wireless communication device 2 of any one lighting device B1 receives a wireless signal from a communication device such as a remote controller, the wireless communication device 2 of that lighting device B1 transmits a wireless signal containing the information (control information) included in the received wireless signal to another lighting device B1. Then, the wireless communication device 2 of the other lighting device B1 receives the wireless signal and transmits it to yet another lighting device B1. Therefore, by having each wireless communication device 2 of the multiple lighting devices B1 send and receive wireless signals in a bucket-brigade fashion, control information can be transmitted to lighting devices B1 that are beyond the reach of the wireless signal from the communication device, enabling remote control such as dimming.

[0093] (3) Effects The power supply board 1 and wireless communication device 2 shown in Figure 1 are housed in a housing 4, with the first connection portion 27 of the wireless communication device 2 (specifically, a plurality of conductors 22) electrically connected to the second connection portion 3 of the power supply board 1 (specifically, a plurality of contacts 31) from a direction perpendicular to one surface 1a of the power supply board 1 (second direction D2). In other words, in power supply device A1, the power supply board 1 and the wireless communication device 2 are electrically connected without the need for wiring such as harnesses.

[0094] If the wireless communication device is connected to the power supply board via wiring such as a harness, it is effective for accommodating various lighting fixtures with different shapes. However, because the wireless communication device is positioned at a distance from the power supply board, it is difficult to miniaturize the power supply unit.

[0095] On the other hand, in power supply unit A1, the power supply board 1 and the wireless communication device 2 are electrically connected without the need for wiring harnesses or other connections, and the wireless communication device 2 is positioned close to the power supply board 1, thus enabling miniaturization. In other words, power supply unit A1 can be made smaller than, for example, when the wireless communication device is connected to the power supply board via wiring harnesses or other connections. Furthermore, because power supply unit A1 can be made smaller, it can be used with a variety of lighting fixtures with different body shapes.

[0096] Furthermore, in power supply unit A1, the power supply board 1 and the wireless communication device 2 are housed within the housing 4 while being electrically connected to each other, so, for example, it is possible to avoid a person directly touching the charging part of the power supply board 1.

[0097] The wireless communication device 2 is positioned perpendicular to one surface 1a of the power supply board 1. This allows the power supply A1 to connect the wireless communication device 2 to the second connection part 3 without being obstructed by, for example, electronic components 11 surrounding the second connection part 3 of the power supply board 1. Therefore, the power supply A1 can improve the ease of connecting the power supply board 1 and the wireless communication device 2.

[0098] The first connection part 27 of the wireless communication device 2 is directly connected to the second connection part 3 located on one side 1a of the power supply board 1. In other words, in the power supply A1, the second module part 21 of the wireless communication device 2 functions as a connector connecting to the second connection part 3 of the power supply board 1. Therefore, the power supply A1 can be made smaller than, for example, a separate connector located in the second module part. In other words, the power supply A1 can be made even smaller.

[0099] Furthermore, the second connection portion 3 of the power supply board 1 and the wireless communication device 2 are arranged within one surface 1a of the power supply board 1 (see Figure 4). As a result, in the power supply device A1, the second connection portion 3 and the wireless communication device 2 do not protrude from one surface 1a of the power supply board 1, thus enabling further miniaturization. In this embodiment, the second connection portion 3 of the power supply board 1 and the wireless communication device 2 are arranged within one surface 1a of the power supply board 1, but it is not essential that they be arranged within one surface 1a of the power supply board 1; for example, a part of the wireless communication device 2 may protrude from one surface 1a of the power supply board 1.

[0100] The first connection part 27 of the wireless communication device 2 includes a conductor 22 that can be electrically connected to the second connection part 3 (see Figure 5). This allows the power supply device A1 to reduce the manufacturing cost of the wireless communication device 2 compared to, for example, a case where the first connection part is a connector.

[0101] The first connection section 27 includes a plurality of conductors 22, which are arranged in a line along one direction (first direction D1) parallel to one surface 1a of the power supply board 1. This makes it easier to connect the first connection section 27 (a plurality of conductors 22) and the second connection section 3 (a plurality of contacts 31) of the power supply unit A1 when the second module section 21 of the wireless communication device 2 is connected to the second connection section 3 of the power supply board 1 from a direction perpendicular to one surface 1a of the power supply board 1 (second direction D2).

[0102] The power supply board 1 includes a power supply circuit 10 that supplies power to a load (in this embodiment, an LED module 50) and a board 100 on which the power supply circuit 10 is arranged. As a result, the power supply device A1 can light up a light source.

[0103] The housing 4 shown in Figure 6 has a plurality of openings 40 (a first opening 40a and a second opening), and each of the plurality of openings 40 allows electromagnetic waves of wireless communication from the wireless communication device 2 to pass through. As a result, in the power supply unit A1, electromagnetic waves radiated from the antenna 24 of the wireless communication device 2 and electromagnetic waves arriving at the antenna 24 can travel back and forth within the housing 4 through at least one of the plurality of openings 40. Therefore, in the power supply unit A1, it is not necessary to expose a part of the wireless communication device 2 (for example, the antenna 24) from the housing 4, and the wireless communication device 2 can be housed inside the housing 4, thus preventing any deterioration in the aesthetic design of the exterior.

[0104] Each of the multiple openings 40 is arranged along one direction (first direction D1) parallel to one surface 1a of the power supply board 1. As a result, the power supply A1 can improve the transmission and reception characteristics of wireless signals compared to, for example, the case where each of the multiple openings is arranged along a direction perpendicular to one surface of the power supply board. Therefore, the power supply A1 can improve the communication performance of the wireless communication device 2.

[0105] Furthermore, each of the multiple openings 40 is positioned in the housing 4 in the thickness direction (third direction D3) of the wireless communication device 2. This allows the power supply A1 to improve, for example, the directivity of electromagnetic waves radiated from the antenna 24 of the wireless communication device 2.

[0106] Each of the multiple apertures 40 is a slot antenna corresponding to the frequency band of the wireless communication by the wireless communication device 2. This allows the power supply A1 to improve the communication performance of the wireless communication device 2.

[0107] The lighting device B1 comprises a power supply A1 and an LED module 50. Since the lighting device B1 includes the aforementioned power supply A1, it can be made smaller.

[0108] (4) Variations Multiple LEDs in the LED module 50 are electrically connected in series, but they may also be electrically connected in series-parallel or in parallel.

[0109] The power conversion circuit 13 may include a switching power supply circuit with power factor correction capabilities, such as a buck chopper circuit, a buck-boost chopper circuit, or a flyback converter, instead of a boost chopper circuit.

[0110] The constant current circuit 14 may include various chopper circuits, series regulators, etc., instead of the step-down chopper circuit.

[0111] The wireless communication device 2 adopts the BLE standard as its wireless communication standard, but it is not limited to the BLE standard and may adopt other standards such as Wi-Fi®, ZigBee®, or low-power radio (for example, low-power radio using a frequency of 920 MHz). In other words, the wireless communication device 2 may adopt any one wireless communication standard such as Bluetooth®, Wi-Fi®, ZigBee®, and low-power radio.

[0112] The second module 21 of the wireless communication device 2 is located at the left end of the first module 20 (see Figure 5), but may be located at the lower end of the first module 20, for example. More specifically, the second substrate 210 may be located at the lower end of the first substrate 200, for example. In this case, the insertion hole 300 of the second connection part 3 is provided, for example, across the upper wall 30a of the main body 30 and two of the four side walls (both side walls in the first direction D1 of the main body 30). That is, the insertion hole 300 is provided in the main body 30 such that it opens up in the upper wall 30a and a part of the above side walls.

[0113] The housing 4 may have, for example, a plurality of transparent sections that each close off a plurality of openings 40. Each of the plurality of transparent sections is, for example, a rectangular plate shape. More specifically, each of the plurality of transparent sections is, for example, an elongated rectangle in plan view. The material of each of the plurality of transparent sections is, for example, a resin that transmits electromagnetic waves of wireless communication from the wireless communication device 2. The size of each of the plurality of transparent sections is, for example, the same as the size of each of the plurality of openings 40. This makes it possible to prevent insects and the like from entering the power supply A1 through the plurality of openings 40 of the housing 4.

[0114] Power supply unit A1 has a function to dim the LED module 50, but may also have a function to adjust the color of the LED module 50. In this case, the LED module 50 includes multiple types of LEDs with different light colors (for example, two types of LEDs, such as incandescent LEDs and daylight LEDs), and the control circuit 15 adjusts the color of the LED module 50 by individually adjusting the first target value of the DC current supplied to the incandescent LEDs and the second target value of the DC current supplied to the daylight LEDs. Also, for example, if the LED module 50 includes three or more LEDs with different light colors such as red, blue, green, and white, the control circuit 15 adjusts the color of the LED module 50 by individually adjusting the target value of the DC current supplied to each color LED.

[0115] In other words, the power supply A1 is configured to adjust at least one of the light intensity and light color emitted from the LED module 50 in accordance with commands (control information) acquired by wireless communication from the wireless communication device 2. This allows the power supply A1 to remotely control the LED module 50 while, for example, achieving miniaturization and reduced wiring.

[0116] The fixture body 6 of the lighting device B1 is directly attached to the ceiling, but for example, it may be embedded in the ceiling, directly attached to the wall, or embedded in the wall.

[0117] The lighting device B1 equipped with power supply A1 is not limited to the lighting devices shown in Figures 8 to 10. For example, as shown in Figure 11, the lighting device B2 equipped with power supply A1 may be a downlight or the like. The lighting device B2 is installed on the ceiling, for example, by being embedded in a recessed hole provided in the ceiling.

[0118] The lighting device B2 comprises, for example, a lamp body 8 and a power supply device A1. The lamp body 8 has a truncated cone-shaped frame 80, a cover 81 that closes the bottom surface of the frame 80, three mounting springs 82, and an LED module (not shown). The LED module is positioned on the bottom surface of the frame 80 and covered by the cover 81. The three mounting springs 82 are fixed to the frame 80 so as to protrude from the edge of the frame 80 along the radial direction of the frame 80. The housing 4 of the power supply device A1 is mounted on the top of the frame 80. In the lighting device B2, it is preferable that multiple openings (slot antennas) are provided in the housing 4 of the power supply device A1. This allows the communication performance of the wireless communication device 2 to be improved in the lighting device B2.

[0119] The lighting device B2 is installed on the ceiling by inserting the power supply device A1 into the ceiling space through the aforementioned mounting hole, and sandwiching the ceiling panel around the mounting hole between the periphery of the frame 80 and the three mounting springs 82.

[0120] Therefore, since the lighting device B2, like the lighting device B1 in this embodiment, is equipped with a power supply A1, it can be miniaturized. In short, the lighting device B2 can also be miniaturized.

[0121] (Embodiment 2) The power supply A2 according to Embodiment 2 differs from the power supply A1 according to Embodiment 1 (Figures 1-4 and 6-7) in that, for example, as shown in Figure 12, the wireless communication device 2 has a connector 17 instead of multiple conductors 22. Regarding the power supply A2 according to Embodiment 2, components similar to those in the power supply A1 according to Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted.

[0122] The power supply unit A2 according to Embodiment 2 will be described below with reference to Figure 12. Note that in Figure 12, the housing 4 is omitted from the illustration to aid in understanding the description of the embodiment.

[0123] The power supply board 1 has, for example, a connection portion 18. In other words, the power supply board 1 has a connection portion 18 instead of the second connection portion 3 of Embodiment 1. The connection portion 18 is configured to be electrically and mechanically connectable to the first connection portion 27 of the wireless communication device 2. The connection portion 18 is, for example, a male connector.

[0124] The connection portion 18 is located on one surface 1a of the power supply board 1. For example, the connection portion 18 is located on one surface 1a of the power supply board 1 at one end (front end) in the front-to-back direction (first direction D1) of the power supply board 1, and at one end (right end) in the left-to-right direction (third direction D3) of the power supply board 1. The connection portion 18 is also electrically connected to the conductor (copper foil) of the board 100.

[0125] The first connection portion 27 of the wireless communication device 2 includes a connector 17. In other words, the wireless communication device 2 includes a connector 17 instead of the multiple conductors 22 of Embodiment 1. The connector 17 is configured to be electrically and mechanically connectable to the connection portion 18 of the power supply board 1. The connector 17 is, for example, a female connector.

[0126] The connector 17 is located on one side 210a of the second circuit board 210 of the wireless communication device 2. In short, the connector 17 is located on the second module section 21. The connector 17 is electrically connected to the wireless communication circuit 26.

[0127] The power supply board 1 and the wireless communication device 2 are housed in the housing 4, with the connector 17 of the wireless communication device 2 electrically connected to the connection portion 18 of the power supply board 1 from a direction perpendicular to one surface 1a of the power supply board 1 (second direction D2). In other words, in power supply unit A2, the power supply board 1 and the wireless communication device 2 are electrically connected without the need for wiring such as harnesses. Therefore, even in power supply unit A2, it is possible to achieve a smaller size than, for example, when the wireless communication device is connected to the power supply board via wiring such as harnesses.

[0128] Furthermore, the wireless communication device 2 has a connector 17 that can be electrically and mechanically connected to the connection portion 18 of the power supply board 1, instead of the multiple conductors 22 of Embodiment 1. This allows the power supply device A2 to maintain a strong connection between the connection portion 18 of the power supply board 1 and the connector 17 of the wireless communication device 2.

[0129] Power supply A2 may be used in place of power supply A1 in Embodiment 1 for lighting devices B1 (Figures 7-10) and B2 (Figure 11). That is, each of lighting devices B1 and B2 may include, for example, power supply A2 and an LED module 50.

[0130] In power supply unit A2, the connection portion 18 of the power supply board 1 is a male connector and the connector 17 of the wireless communication device 2 is a female connector. However, the connection portion 18 of the power supply board 1 may be a female connector and the connector 17 of the wireless communication device 2 may be a male connector.

[0131] The embodiments 1 and 2 and their variations described above are only a part of the various embodiments and variations of this disclosure.

[0132] This disclosure is not limited to the embodiments described above, and it is possible to combine and apply at least some of the configurations of each embodiment and modification as appropriate.

[0133] (Aspect) This specification discloses the following aspects:

[0134] The power supply device (A1; A2) according to the first embodiment comprises a power supply board (1), a wireless communication device (2), and a housing (4). The wireless communication device (2) performs wireless communication using electromagnetic waves as a medium. The housing (4) houses the power supply board (1) and the wireless communication device (2). The wireless communication device (2) has a first connection part (27) for electrically connecting to the power supply board (1). The power supply board (1) has a second connection part (3; 18) which is electrically connected to the first connection part (27) of the wireless communication device (2).
