MODE FOR CARRYING OUT THE INVENTION

[0011] Hereinafter, a power supply device and a lighting device according to embodiments of the present disclosure will be described in detail with reference to the drawings. However, each drawing 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) Overview The power supply device A1 according to the embodiment includes a power supply block 1 that supplies power to a load, a wireless communication device 2 that performs wireless communication, and a regulating member (see FIG. 1). Note that the load to which power is supplied from the power supply block 1 is preferably a light-emitting element (light source) such as a light-emitting diode (LED), an organic electroluminescence element, or a laser diode.

[0013] The wireless communication device 2 controls the power supply block 1 so as to adjust the power according to a command acquired by wireless communication. The wireless communication device 2 preferably receives a wireless signal transmitted from a communication device such as a remote controller or a smartphone, and controls the power supply block 1 according to the command included in the wireless signal. Note that the communication medium for wireless communication is preferably an electromagnetic wave such as radio waves, infrared rays, or visible light, and radio waves are particularly desirable.

[0014] The power supply block 1 has a plate-shaped power supply substrate 10 on which circuit components 11 are mounted on a surface 100, and a connection portion 3 provided on the power supply substrate 10 and electrically connected to the wireless communication device 2.

[0015] The power supply board 10 is, for example, made up of a rectangular printed circuit board. The circuit components 11 include two types of circuit components: through-hole components and surface-mount components. The through-hole components 11 are mounted on the component side (surface 100) of the power supply board 10. The surface-mount components are mainly mounted on the solder side (backside) of the power supply board 10. However, some surface-mount components may also be mounted on the component side (surface 100).

[0016] The connection part 3 is configured to electrically connect to the wireless communication device 2 in a removable manner. Preferably, the connection part 3 has, for example, a receptacle connector (female connector). If the connection part 3 has a receptacle connector, it is preferable that the wireless communication device 2 has a plug connector (male connector) that can be electrically and mechanically connected to the receptacle connector. However, it is also acceptable for the connection part 3 to have a plug connector and the wireless communication device 2 to have a receptacle connector.

[0017] The restricting member restricts the movement of the wireless communication device 2, which is electrically connected to the connection part 3, in the direction of disengaging from the connection part 3 (first direction D1) (see Figure 5). The restricting member has, for example, a recess 101 provided on the power supply board 10 and a protrusion 25 provided on the wireless communication device 2 that can mate with the recess 101. That is, when the connection part 3 and the wireless communication device 2 are electrically connected, the protrusion 25 of the wireless communication device 2 mates with the recess 101 of the power supply board 10, so the movement of the wireless communication device 2 in the direction of disengaging from the connection part 3 (first direction D1) is restricted (see Figure 5).

[0018] However, since the power supply A1 according to this embodiment restricts the movement of the wireless communication device 2 with a restricting member (recess 101 and protrusion 25), the electrical connection between the power supply block 1 and the wireless communication device 2 via the connection part 3 is less likely to be released. As a result, the power supply A1 according to this embodiment can improve the reliability of the electrical connection between the power supply block 1 and the wireless communication device 2.

[0019] Furthermore, the lighting device B1 according to the embodiment includes a power supply device A1 according to the embodiment and one or more light sources (LED modules 50) that are lit by the power supplied from the power supply device A1 according to the embodiment (see Figure 18).

[0020] Since the lighting device B1 according to this embodiment includes the power supply device A1 according to this embodiment, the reliability of the electrical connection between the power supply block 1 and the wireless communication device 2 can be improved.

[0021] (2) Details (2-1) Details of the power supply The power supply device A1 according to this embodiment (hereinafter referred to as power supply device A1) comprises a power supply block 1, a wireless communication device 2, and a regulating member (see Figures 1 and 5).

[0022] (2-1-1) Circuit configuration of the power supply unit Figure 4 shows the circuit configuration of power supply unit A1. Power supply unit A1 comprises a power supply block 1 and a wireless communication device 2.

[0023] The power supply block 1 includes a power connector 12, a power conversion circuit 13, a constant current circuit 14, a control circuit 15, a connection part 3, and the like.

[0024] The power conversion circuit 13 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 13 converts AC power supplied from an external power supply P1 through a power connector 12 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 13 may include a switching power supply circuit with 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.

[0025] The constant current circuit 14 includes, for example, a buck converter. The constant current circuit 14 steps down the DC voltage output from the power conversion circuit 13 and applies it to the LED module 50, and also adjusts the DC current flowing through the LED module 50. However, the constant current circuit 14 may be equipped with various chopper circuits, series regulators, etc., instead of a buck converter.

[0026] The control circuit 15 includes, for example, a microcontroller. The control circuit 15 controls the power conversion circuit 13 to maintain its output voltage at a constant DC voltage. Furthermore, the control circuit 15 controls the step-down chopper circuit of the constant current circuit 14 to match the DC current supplied from the constant current circuit 14 to the LED module 50 to a target value. The control circuit 15 is electrically connected to the wireless communication device 2 via the connection part 3. As will be described later, the control circuit 15 changes the target value of the DC current supplied to the LED module 50 in response to a control signal received from the wireless communication device 2.

[0027] The wireless communication device 2 includes a wireless communication circuit 23, an antenna 24, etc. (see Figure 2). The wireless communication circuit 23 is an integrated circuit configured to perform wireless communication compliant with a wireless communication standard, such as BLE (Bluetooth® low energy). However, the wireless communication circuit 23 only needs to be configured to perform wireless communication compliant with any one standard, such as BLE, Wi-Fi®, ZigBee®, and 920MHz band low-power radio stations (for telecontrol). The wireless communication circuit 23 can send and receive wireless signals through the external antenna 24. The wireless communication device 2 operates by receiving a control power supply voltage from the power supply block 1 through the connection part 3.

[0028] The connection section 3 has, for example, four contacts 31 (see Figure 2). The four contacts 31 include a ground contact, a control power supply voltage contact, and two control signal contacts.

[0029] However, the wireless communication circuit 23 of the wireless communication device 2 acquires a control signal from the wireless signal received via the antenna 24 and outputs the acquired control signal to the control circuit 15 of the power supply block 1 via the connection unit 3. The control circuit 15 dims the LED module 50 by changing the target value of the DC current supplied to the LED module 50 according to the control signal received from the wireless communication circuit 23. If 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, the control circuit 15 can also adjust the color of the LED module 50 by individually adjusting the target value of the DC current supplied to the incandescent LEDs and the target value of the DC current supplied to the daylight LEDs.

[0030] (2-1-2) Structure of the power supply unit The power supply block 1 has a board-shaped power supply board 10 on which multiple circuit components 11 are mounted on its surface 100 (see Figure 1). The power supply board 10 is, for example, made of a rectangular printed circuit board. A power connector 12 is mounted on one end of the power supply board 10 in the longitudinal direction (the left end in Figure 1). The multiple circuit components 11 include two types of circuit components: through-hole components and surface-mount components. Through-hole components 11 are mounted on the surface 100, which is the component side of the power supply board 10 (see Figure 1). Surface-mount components are mainly mounted on the back side, which is the solder side of the power supply board 10. However, some surface-mount components may also be mounted on the component side (surface 100). The power conversion circuit 13, constant current circuit 14, and control circuit 15 of the power supply block 1 are made of printed circuits consisting of the power supply board 10 and the multiple circuit components 11.

[0031] The wireless communication device 2 has a plate-shaped wireless communication substrate 20 (see Figure 2). A wireless communication circuit 23 is mounted on the surface 200 of the wireless communication substrate 20. An antenna 24 is also provided on the surface 200 of the wireless communication substrate 20. The antenna 24 is made of a conductor (copper foil) formed on the surface 200 of the wireless communication substrate 20.

[0032] A projection 21 is provided at one end (the left end in Figure 2) of the wireless communication board 20 in the longitudinal direction (first direction D1) (see Figure 2). The projection 21 is rectangular in shape, shorter than the width dimension in the short direction (second direction D2) of the wireless communication board 20, and is integrally formed with the wireless communication board 20. Four conductors 22 are provided on the surface 210 of the projection 21 (see Figure 2). Each of the four conductors 22 is formed in a rectangular shape with the first direction D1 as its longitudinal direction. The four conductors 22 are also arranged parallel to each other with a gap in between along the second direction D2. These four conductors 22 are electrically connected to the wireless communication circuit 23. For example, the two conductors 22 at both ends in the second direction D2 are configured to make one-to-one contact and conduct electricity with the ground contact 31 and the control power supply voltage contact 31 of the connection part 3. The remaining two conductors 22 are configured to make one-to-one contact and conduct electricity with the two control signal contacts 31 of the connection part 3.

[0033] The connection part 3 has a box body 30 having an opening 300 into which the protruding piece 21 is inserted, four contacts 31 provided inside the box body 30, four terminals 32 electrically connected one-to-one with each contact 31, and four leg pieces 33 (see Figure 2). In this embodiment, the connection part 3 is made up of a general-purpose receptacle connector (Type A) compliant with the USB (Universal Serial Bus) standard, but it is not intended to limit the design to this.

[0034] The box body 30 is formed into a bottomed rectangular tube shape by processing a metal plate. The four leg pieces 33 protrude from the side of the box body 30 along the second direction D2. However, the four leg pieces 33 are integrally formed with the box body 30 by the metal plate.

[0035] The four contacts 31 are supported by a rectangular support (not shown) made of an electrically insulating material (e.g., synthetic resin) and housed inside the box 30. The tips of the four contacts 31 are bent into a V-shape (see Figure 3). However, the tips of the contacts 31 may be bent into a U-shape. The four terminals 32 protrude from the side of the box 30 along the second direction D2. The four terminals 32 are also arranged in a row with spacing between them along the first direction D1.

[0036] The connector 3 is mounted on the surface 100 of the power supply board 10, located near one end (the left end in Figure 1) from the center in the longitudinal direction of the power supply board 10, and at one end (the rear side in Figure 1) in the short direction of the power supply board 10. However, the connector 3 is mounted on the power supply board 10 such that the opening 300 of the casing 30 faces the other end (the right end in Figure 1) in the longitudinal direction (first direction D1) of the power supply board 10. The four terminals 32 of the connector 3 are inserted one by one into the four through-holes provided on the power supply board 10 and soldered to the printed circuit board on the back side (solder side) of the power supply board 10.

[0037] The wireless communication device 2 is mechanically and electrically connected to the connection part 3 by inserting the projection 21 into the opening 300 of the box body 30 in the opposite direction to the first direction D1 (see Figures 1 and 2). The projection 21 inserted into the box body 30 from the opening 300 is positioned in the space between the inner surface of the box body 30 and the support. The four conductors 22 provided on the surface 210 of the projection 21 then make one-to-one contact and conduction with the four contacts 31 supported by the support. At this time, the V-shaped bent tip deforms, generating contact pressure on each contact 31 against the conductor 22, ensuring reliable contact and conduction between each contact 31 and each conductor 22.

[0038] The regulating member has a protrusion 25 provided on the wireless communication board 20 and a recess 101 provided on the power supply board 10 (see Figures 2 and 5-7).

[0039] The recess 101 includes a first recess 101A and a second recess 101B (see Figure 5). The first recess 101A and the second recess 101B are each rectangular through-holes that penetrate the power supply board 10 in the thickness direction, with the first direction D1 as the longitudinal direction. However, the length of the second recess 101B in the longitudinal direction (first direction D1) is shorter than the length of the first recess 101A in the longitudinal direction. Furthermore, the first recess 101A and the second recess 101B are aligned in a straight line along the first direction D1, with the second recess 101B sandwiched between the connection portion 3 and the first recess 101A (see Figure 5).

[0040] The protrusion 25 is formed in a pyramidal truncated shape and protrudes in a second direction D2 from the lower surface (the surface facing the surface 100 of the power supply board 10) of the other end (the right end in Figure 2) in the longitudinal direction of the wireless communication board 20 (see Figure 2). Here, the protrusion 25 has a facing surface 250 that faces the second recess 101B in the direction in which the wireless communication device 2 is inserted into the connection part 3 (opposite direction to the first direction D1) (see Figures 2 and 5). The facing surface 250 is inclined to move away from the second recess 101B in the direction in which the wireless communication device 2 is removed from the connection part 3 (first direction D1) (see Figures 2 and 5).

[0041] The wireless communication device 2 is mechanically and electrically connected to the connection part 3 by inserting the projection 21 into the opening 300 of the box body 30 in the opposite direction to the first direction D1 (see Figures 1 and 2). The procedure for connecting the wireless communication device 2 to the connection part 3 will now be described in detail.

[0042] First, the worker performing the connection inserts the protrusion 25 of the wireless communication board 20 into the first recess 101A (see Figure 6). Then, the worker moves the wireless communication device 2 in the opposite direction to the first direction D1 (to the left in Figure 6) and inserts the projection 21 into the opening 300 of the box body 30 of the connection part 3. At this point, the protrusion 25 inserted into the first recess 101A moves towards the second recess 101B within the first recess 101A as the wireless communication device 2 moves. When the protrusion 25 reaches the longitudinal end of the first recess 101A, the boundary portion 102 of the power supply board 10 between the first recess 101A and the second recess 101B is pressed by the protrusion 25 and bends (see Figure 7). Once the worker has finished inserting the projection 21 into the box body 30 through the opening 300, the protrusion 25 moves over the boundary portion 102 of the power supply board 10 and engages with the second recess 101B (see Figure 5).

[0043] The projection 21 inserted into the box body 30 through the opening 300 is positioned in the space between the inner surface of the box body 30 and the support. The four conductors 22 provided on the surface 210 of the projection 21 then make one-to-one contact with the four contacts 31 supported by the support. At this time, the V-shaped bent tip deforms, generating contact pressure on each contact 31 against the conductor 22, ensuring reliable contact and electrical connection between each contact 31 and each conductor 22 (see Figure 3).

[0044] As described above, the wireless communication device 2 connected to the connection part 3 is restricted by the restricting member from moving in the direction of detachment from the connection part 3 (first direction D1). Therefore, the power supply device A1 can prevent the protruding piece 21 of the wireless communication device 2 from unintentionally coming out of the opening 300 of the connection part 3.

[0045] However, since the power supply unit A1 restricts the movement of the wireless communication device 2 with a restricting member, the electrical connection between the power supply block 1 and the wireless communication device 2 via the connection part 3 is less likely to be released. As a result, the power supply unit A1 can improve the reliability of the electrical connection between the power supply block 1 and the wireless communication device 2.

[0046] Furthermore, since the restricting member in power supply unit A1 restricts the movement of the wireless communication device 2 through the interlocking of the recessed portion 101 and the convex portion 25, the restricting member can be realized with a relatively simple structure. As a result, power supply unit A1 can reduce the manufacturing cost of the restricting member.

[0047] Furthermore, the power supply unit A1 may have a protrusion on the power supply board 10 and a recess (a first recess and a second recess) on the wireless communication board 20. However, if the power supply board 10 is provided with a recess 101 (a first recess 101A and a second recess 101B) and the wireless communication board 20 is provided with a protrusion 25 as described above, there is an advantage in that the manufacturing cost of the regulating member can be reduced compared to the case where the power supply board 10 is provided with a protrusion.

[0048] Furthermore, the power supply unit A1 includes a first recess 101A and a second recess 101B in the recess 101, which are aligned along the insertion and removal direction of the wireless communication device 2. The protrusion 25 is configured to move from the first recess 101A to the second recess 101B when the wireless communication device 2 is moved in the direction in which it is inserted into the connection unit 3 (opposite direction to the first direction D1). Therefore, as described in the connection procedure above, the operator can electrically connect the connection unit 3 and the wireless communication device 2 by moving the wireless communication device 2 in the direction opposite to the first direction D1.

[0049] However, compared to the case where only the second recess 101B is provided and the first recess 101A is not provided, the power supply A1 can improve the workability when connecting the wireless communication device 2 to the connection part 3.

[0050] Furthermore, as described above, the opposing surface 250 of the protrusion 25 is inclined to move away from the second recess 101B in the direction in which the wireless communication device 2 is removed from the connection part 3 (first direction D1) (see Figures 2 and 5). In other words, when the opposing surface 250 of the protrusion 25 hits the boundary portion 102 between the first recess 101A and the second recess 101B during the process of inserting the wireless communication device 2 into the connection part 3, the boundary portion 102 is subjected to a downward force along the inclination of the opposing surface 250 and bends. Therefore, by making the opposing surface 250 of the protrusion 25 of the power supply device A1 an inclined surface, the protrusion 25 of the wireless communication device 2 can smoothly overcome the boundary portion 102. As a result, the power supply device A1 can improve the workability of the connection work between the connection part 3 and the wireless communication device 2.

[0051] (2-1-3) Modified Power Supply Device Next, several modifications of the power supply unit A1 according to the embodiment will be described with reference to the drawings. However, the basic configuration of each modification of power supply unit A1 described below is the same as the basic configuration of power supply unit A1 according to the embodiment. Therefore, components that are common to or substantially common with the basic configuration of power supply unit A1 according to the embodiment will be denoted by the same reference numerals, and their illustration and description will be omitted as appropriate. In the following description, "substantially common components" means components that differ slightly in shape, size, etc., but have the same function.

[0052] (2-1-3-1) Variation 1 The power supply A1 of the modified example 1 is characterized in that the wireless communication substrate 20 has a flexible portion 26 that can bend in the opposite direction to the protruding direction (second direction D2) of the protrusion portion 25 (see Figures 8 and 9).

[0053] The flexible portion 26 is formed integrally with the wireless communication board 20 in a cantilever shape. A protrusion 25 is provided at the tip of the flexible portion 26 (the end opposite to the fixed end fixed to the wireless communication board 20). The protrusion 25 projects from the tip of the flexible portion 26 in a second direction D2 (see Figures 8 and 9). Note that in Figures 8 and 9, various circuit components mounted on the wireless communication board 20, including the wireless communication circuit 23 and antenna 24, are not shown.

[0054] Next, the procedure for connecting the wireless communication device 2 to the connection part 3 will be explained.

[0055] First, the worker performing the connection work moves the wireless communication device 2 in the opposite direction to the first direction D1 (to the left in Figure 9) and inserts the projection 21 into the opening 300 of the housing 30 of the connection part 3. At this time, the convex portion 25 comes into contact with the surface 100 of the power supply board 10, causing the flexible portion 26 to bend in the opposite direction to the second direction D2. Then, when the worker has finished inserting the projection 21 into the housing 30 through the opening 300, the flexible portion 26 returns to its original state and the convex portion 25 engages with the recess 101 of the power supply board 10 (see Figure 8).

[0056] In the above procedure, the wireless communication device 2 connected to the connection part 3 is restricted from moving in the direction of detachment from the connection part 3 (first direction D1) by the restricting members (protrusion 25, flexible part 26, and recess 101). Therefore, the power supply device A1 of the modified example 1 can prevent the protrusion 21 of the wireless communication device 2 from unintentionally detaching from the opening 300 of the connection part 3, similar to the embodiment.

[0057] In this modified example, the power supply A1 in Modified Example 1 can reduce the size of the recess 101 provided on the power supply board 10 compared to the power supply A1 in the embodiment, thereby expanding the mounting area for circuit components 11 and the conductor formation area on the power supply board 10.

[0058] (2-1-3-2) Modification example 2 Modified example A1 is characterized in that the recess 101 provided on the power supply board 10 is elongated, and a projection 103 protruding from the inner surface along the longitudinal direction of the elongated recess 101 serves as a regulating member (see Figures 10 and 11).

[0059] The projection 103 is formed in a triangular prism shape. The projection 103 protrudes from each of a pair of inner surfaces facing each other in the short direction at one end of the recess 101 in the longitudinal direction (the end opposite to the first direction D1) (see Figures 10 and 11). In other words, the recess 101 is configured to partially narrow its width dimension (the distance between the pair of inner surfaces facing each other in the short direction) by the pair of projections 103.

[0060] Next, the procedure for connecting the wireless communication device 2 to the connection part 3 will be explained.

[0061] First, the worker performing the connection inserts the protrusion 25 of the wireless communication board 20 into the recess 101 of the power supply board 10. At this time, the worker inserts the protrusion 25 into the recess 101 at a position furthest from the connection part 3 relative to the pair of protrusions 103 (see Figure 11).

[0062] Then, the worker moves the wireless communication device 2 in the opposite direction to the first direction D1 (to the left in Figure 11) and inserts the projection 21 into the opening 300 of the box body 30 of the connection part 3. At this time, the convex part 25 comes into contact with the pair of protrusions 103, causing the power supply board 10 to deform and the distance between the pair of protrusions 103 to widen, and eventually the convex part 25 moves over the pair of protrusions 103 (see Figure 10). When the worker has finished inserting the projection 21 into the box body 30 through the opening 300, the convex part 25 fits between one end of the recess 101 in the longitudinal direction and the pair of protrusions 103 (see Figure 10).

[0063] In the above-described procedure, the wireless communication device 2 connected to the connection part 3 is restricted from moving in the direction of detachment from the connection part 3 (first direction D1) by the restricting members (protrusion 25, recess 101, and pair of projections 103). Therefore, the power supply device A1 of the modified example 2 can prevent the protruding piece 21 of the wireless communication device 2 from unintentionally detaching from the opening 300 of the connection part 3, similar to the embodiment.

[0064] In this modified example, the power supply A1 in Modified Example 2 can reduce the number of recesses 101 provided on the power supply board 10 to one, compared to the power supply A1 in the embodiment, thereby expanding the mounting area for circuit components 11 and the conductor formation area on the power supply board 10.

[0065] (2-1-3-3) Modification 3 The power supply A1 of Modified Example 3 is characterized by the structure of the recess 101 of the restricting member. In Modified Example 3, the recess 101 is formed such that the width W2 of the tip portion 104 in the insertion direction (opposite direction to the first direction D1) is narrower than the width W1 of the portion excluding the tip portion 104 (see Figures 12-14). In Modified Example 3, the protrusion 25 of the wireless communication board 20 has a width greater than or equal to the width W2 of the tip portion 104 (see Figure 14).

[0066] In other words, in the modified example 3, the recess 101, when viewed from the thickness direction of the power supply board 10, is formed with a tapered trapezoidal tip portion 104 and a rectangular shape for the portion other than the tip portion 104.

[0067] On the other hand, the protrusion 25 in modified example 3 is longer in length along the longitudinal direction of the wireless communication substrate 20 compared to the protrusion 25 in the embodiment and modified examples 1-2, and is formed to be slightly shorter than the length of the wireless communication substrate 20 excluding the protrusion 21.

[0068] Next, the procedure for connecting the wireless communication device 2 to the connection part 3 will be explained.

[0069] First, the worker performing the connection work inserts the protruding portion 25 of the wireless communication board 20 into the portion of the recessed portion 101 other than the tip portion 104 (see Figure 13).

[0070] Then, the worker moves the wireless communication device 2 in the opposite direction to the first direction D1 (to the left in Figure 13) and inserts the projection 21 into the opening 300 of the box body 30 of the connection part 3. At this time, the convex part 25 moves within the recess 101 in the opposite direction to the first direction D1. When the worker has finished inserting the projection 21 into the box body 30 through the opening 300, the tip of the convex part 25 is pressed into the tip portion 104 of the recess 101 (see Figures 12 and 14).

[0071] In the procedure described above, the wireless communication device 2 connected to the connection part 3 is restricted from moving in the direction of detachment from the connection part 3 (first direction D1) by the restricting members (protrusion 25 and recess 101). Therefore, the power supply device A1 of the modified example 3, like the embodiment, can prevent the protrusion 21 of the wireless communication device 2 from unintentionally detaching from the opening 300 of the connection part 3.

[0072] In this modified example 3, the power supply A1 does not require bending a part of the power supply board 10 (boundary portion 102) compared to the power supply A1 according to the embodiment, thus reducing the mechanical stress applied to the power supply board 10.

[0073] (2-1-3-4) Modification 4 The power supply unit A1 of the modified example 4 is characterized by electrically connecting the wireless communication device 2 and the connection part 3 from a direction (second direction D2) opposite to the surface 100 of the power supply board 10.

[0074] In Modification 4, the connection section 3 has rectangular openings 301 and 302 on each of two adjacent sides of the box body 30 (see Figures 15 and 16). These two openings 301 and 302 are connected at one end in the longitudinal direction of each. In Modification 4, the connection section 3 has four contacts 31 housed inside the box body 30, arranged at intervals along the surface 100 of the power supply board 10 (see Figure 16).

[0075] In the modified example 4, the wireless communication device 2 has four conductors 22 that make one-to-one contact and conduction with the four contacts 31 of the connection part 3, and these conductors are formed on the surface of the projection 21 so as to be spaced apart along the longitudinal direction (first direction D1) of the wireless communication substrate 20 (see Figure 16). In addition, the wireless communication device 2 in the modified example 4 has a convex portion 25 and a flexible portion 26 at the rear end of the wireless communication substrate 20 (the end opposite to the front end from which the projection 21 protrudes).

[0076] The flexible portion 26 is formed in a cantilever shape at the rear end of the wireless communication substrate 20. The flexible portion 26 is capable of bending toward the rear end of the wireless communication substrate 20. The protrusion 25 is provided at the tip of the flexible portion 26.

[0077] Next, the procedure for connecting the wireless communication device 2 to the connection part 3 will be explained.

[0078] First, the worker performing the connection inserts the projection 21 of the wireless communication device 2 into the openings 301 and 302 of the housing 30 from the second direction D2. At this time, the convex portion 25 contacts the surface 100 of the power supply board 10, causing the flexible portion 26 to bend toward the wireless communication board 20. Then, once the worker has finished inserting the projection 21 into the housing 30 through the openings 301 and 302, the flexible portion 26 returns to its original state and the convex portion 25 engages with the recess 101 of the power supply board 10 (see Figure 15).

[0079] In the procedure described above, the wireless communication device 2 connected to the connection part 3 is restricted from moving in the direction opposite to the second direction D2 by the restricting members (protrusion 25, flexible part 26, and recess 101). Therefore, the power supply device A1 of the modified example 4 can prevent the protruding piece 21 of the wireless communication device 2 from unintentionally coming out of the opening 300 of the connection part 3, similar to the embodiment.

[0080] Furthermore, in Modified Example 4, the power supply A1 electrically connects the wireless communication device 2 and the connection part 3 from a direction (second direction D2) opposite to the surface 100 of the power supply board 10, so that the wireless communication device 2 can be connected to the connection part 3 without being obstructed by the circuit components 11 surrounding the connection part 3. As a result, Modified Example 4's power supply A1 can improve the workability of connecting the wireless communication device 2 and the connection part 3. Moreover, compared to the power supply A1 according to the embodiment, Modified Example 4's power supply A1 can reduce the size of the recess 101 provided on the power supply board 10, thus expanding the mounting area for circuit components 11 and the conductor formation area on the power supply board 10.

[0081] (2-2) Details of the lighting equipment The lighting device B1 according to this embodiment (hereinafter abbreviated as lighting device B1) comprises a light source unit 5 and a fixture body 6 that supports the light source unit 5 (see Figures 17-19). The light source unit 5 is detachably attached to the fixture body 6 which is directly attached to the ceiling. However, the fixture body 6 may be embedded in the ceiling. Alternatively, the fixture body 6 may be directly attached to the wall or embedded in the wall.

[0082] (2-2-1) Main body of the device The main body of the device 6 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 along the longitudinal direction of the housing section 60, and a pair of end plates 62 provided at both ends of the housing section 60 and the pair of reflectors 61 in the longitudinal direction (see Figures 18 and 19). The housing section 60 and the pair of reflectors 61 are integrally formed by punching and bending metal plates.

[0083] The fixture body 6 is installed on the ceiling by inserting suspension bolts through at least two of the multiple mounting holes 63 provided on the bottom (top) surface of the housing 60, and tightening nuts 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.

[0084] A terminal block 65 is attached to the bottom of the housing section 60 (see Figure 18). The terminal block 65 is electrically connected to the power lines. The ends of the power lines are provided with power connectors (not shown) that are electrically connected to the power connector 12 of the power supply unit A1.

[0085] However, the power cable inserted through the power hole 64 of the fixture body 6 is electrically connected to the terminal block 65, and via the terminal block 65, power line, and power connector, is electrically connected to the power supply A1 of the light source unit 5.

[0086] The housing section 60 has a pair of hooking holes and a pair of hooking parts 601 located near both ends in its longitudinal direction (see Figure 18). The pair of hooking holes are provided on the side wall of one end of the housing section 60 in the short direction. The pair of hooking parts 601 are positioned on the upper part of the other end of the housing section 60 in the short direction (see Figure 18).

[0087] (2-2-2) Light source unit As shown in Figures 18 and 19, the light source unit 5 comprises an LED module 50, a mounting member 51, a cover 52, and a power supply A1.

[0088] The LED module 50 has two substrates 500 and a number of LEDs (Light Emitting Diodes) mounted on the surface (bottom surface) of each substrate 500 (see Figure 18). The light-emitting element, an LED (not shown), is, for example, a packaged white LED for illumination. However, the light-emitting element is not limited to an LED, and may be an organic electroluminescent element or a semiconductor laser element, etc. The number of substrates 500 in the LED module 50 is not limited to two, and may be three or more, or even just one.

[0089] Each circuit board 500 is formed in a long rectangular shape. Numerous LEDs are mounted in a single row at equal intervals along the longitudinal direction of each circuit board 500, in the center of the short side of the surface (bottom surface) of each circuit board 500. The numerous LEDs are electrically connected in series or series-parallel by printed wiring formed on the surface of each circuit board 500. In addition, two sets of connectors 502 are mounted on one end of the longitudinal side of the surface of each circuit board 500 (see Figure 18). The printed wiring formed on the surface of each circuit board 500 is electrically connected via the two sets of connectors 502.

[0090] The mounting member 51 is formed from a metal plate into a long, rectangular trough shape (see Figures 18 and 19). The mounting member 51 has a long, rectangular base plate 510 and a pair of side plates 511 that rise upward from both ends along the longitudinal direction of the base plate 510. The LED module 50 is attached to the underside of the base plate 510 by a plurality of claws 512 that are cut out from the base plate 510 (see Figure 18).

[0091] The mounting member 51 is provided with a pair of hook fittings 513 that protrude outwards from one end in the short direction near both ends in the longitudinal direction (see Figures 18 and 19). Furthermore, the mounting member 51 is provided with a pair of hook springs 514 at the other end in the short direction near both ends in the longitudinal direction (see Figure 19). 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, as will be described later.

[0092] Power supply unit A1 is constructed by adding a housing 4 to power supply unit A1 according to the embodiment. The housing 4 is formed in the shape of a long box with one side open, using a metal plate. Power supply unit A1 is attached to the bottom plate 510 of the mounting member 51 so that the opening of the housing 4 faces the upper surface of the bottom plate 510 (see Figure 19).

[0093] The cover 52 has a long, semi-cylindrical cover body 520, a pair of cover ends 521 attached to each of the longitudinal ends of the cover body 520, a pair of protruding walls 522, and a pair of extensions 523 (see Figures 18 and 19). However, the shape of the cover body 520 is not limited to a long, semi-cylindrical shape, but can be any shape such as a rectangular tube.

[0094] The pair of extensions 523 project inward from both ends of the cover body 520 in the short direction along the longitudinal direction of the cover body 520. The pair of protruding walls 522 project upward from the pair of extensions 523 along the longitudinal direction of the cover body 520 (see Figure 19). The cover body 520, the pair of protruding walls 522, and the pair of extensions 523 are integrally formed from a translucent synthetic resin such as acrylic resin or polycarbonate resin.

[0095] The pair of cover ends 521 are formed in a semi-circular shape in plan view from a material having the same light-transmitting properties as the cover body 520. The pair of cover ends 521 are attached one to each of the longitudinal ends of the cover body 520. In other words, both longitudinal ends of the cover body 520 are closed by the cover ends 521.

[0096] The cover 52 houses the mounting member 51 between a pair of protruding walls 522, and is attached to the mounting member 51 by 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 19).

[0097] 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. While the light source unit 5 is temporarily suspended, wiring work such as connecting the power connector of the power cable to the power connector 12 of the power supply unit A1 is performed. After the wiring work is completed, the light source unit 5 is hooked onto a pair of hook springs 514 one by one into a pair of hook sections 601, and then pressed against the fixture body 6 from below so that the power supply unit A1 is housed in the housing section 60, and is held in place by the spring force of the pair of hook springs 514 (see Figure 17).

[0098] (2-2-3) Operation of the lighting device Lighting devices B1 are installed, for example, on the ceiling of an office. Often, multiple lighting devices B1 are installed on the office ceiling in a row, spaced apart both vertically and horizontally. 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 of the lighting devices B1 receives a wireless signal from a remote controller or the like, the wireless communication device 2 of the lighting device B1 that received the wireless signal transmits a wireless signal containing the control information included in the received wireless signal. Then, the wireless communication devices 2 of one or more other lighting devices B1 receive the wireless signal and transmit the received wireless signal further. In this way, the wireless communication devices 2 of multiple lighting devices B1 send and receive wireless signals in a bucket brigade-like fashion, enabling remote control of dimming, color adjustment, etc., by transmitting control information to lighting devices B1 that are beyond the reach of the remote controller's wireless signal.

[0099] (2-3) Modified lighting devices Next, several modifications of the lighting device B1 according to the embodiment will be described with reference to the drawings. However, the basic configurations of the lighting devices B1, B2, and B3 of each modification described below are the same as the basic configuration of the lighting device B1 according to the embodiment. Therefore, components that are common to or substantially common with the basic configuration of the lighting device B1 according to the embodiment will be denoted by the same reference numerals, and their illustration and description will be omitted as appropriate. In the following description, "substantially common components" means components that differ slightly in shape, size, etc., but have the same function.

[0100] (2-3-1) Variation 1 The lighting device B2 in Modified Example 1 is a so-called spotlight and is detachably attached to a lighting wiring duct (also called a lighting duct) (see Figure 20). In the following description, the front-to-back, left-to-right, and up-and-down directions of the lighting device B2 in Modified Example 1 are defined as follows, assuming that the axial direction (longitudinal direction) of the main body 70 and the longitudinal direction of the arm 75 are perpendicular to each other, as shown in Figure 20. That is, the longitudinal direction of the arm 75 is defined as the up-and-down direction, the axial direction of the main body 70 (the direction perpendicular to the longitudinal direction of the arm 75) is defined as the front-to-back direction, and the direction perpendicular to the up-and-down direction and the front-to-back direction is defined as the left-to-right direction (see arrows in Figure 20).

[0101] The lighting device B2 of the modified example 1 comprises a luminaire B21, an arm 75, and a plug unit B22 (see Figure 20). The plug unit B22 is mechanically and electrically detachably attached to a lighting wiring duct installed on the ceiling or the like. The arm 75 is rotatably attached to the lower part of the plug unit B22. The axis of rotation of the arm 75 is parallel to the vertical direction. The luminaire B21 is supported by the arm 75 so as to be rotatable in a plane including the vertical and front-back directions. However, the rotatable range of the luminaire B21 is approximately 90 degrees, from a position where the axial direction of the main body 70 is perpendicular to the longitudinal direction (vertical direction) of the arm 75 (see Figure 20) to a position where the axial direction of the main body 70 is parallel.

[0102] The lighting fixture B21 comprises a main body 70, a light source unit 72, a lens unit 73, a power supply A2, an end cover 76, and the like (see Figures 20 and 21).

[0103] The main body 70 has a first main body portion 701 and a second main body portion 702. The first main body portion 701 and the second main body portion 702 are each formed by die-casting an aluminum alloy into a cylindrical shape with open ends. The first main body portion 701 and the second main body portion 702 have the same diameter but different axial lengths. The second main body portion 702 is formed to be longer in the axial length than the first main body portion 701.

[0104] The second main body 702 has a rectangular slit 703 formed from its rear end to the axial center. The width (distance in the left-right direction) of the slit 703 is wider than the width of the arm 75.

[0105] The light source unit 72 includes an LED 720 which is the light source, a holder 721, a pair of connectors 722, a thermal conductive sheet, and a unit body 724 (see Figure 21). The LED 720 is a COB (Chip on Board) type white LED for lighting. The unit body 724 is formed in a disc shape by die-casting an aluminum alloy.

[0106] A rectangular recess is provided in the center of the front of the unit body 724. A rectangular heat conductive sheet is housed in this recess. In addition, one screw insertion hole 725 and one screw hole 726 are provided on both the left and right ends of the unit body 724 (see Figure 21).

[0107] A holder 721 for holding the LED 720 is attached to the front of the unit body 724. The holder 721 is made of synthetic resin and is formed in a frame shape with a square window opening in the center. The holder 721 holds the LED 720 by fitting it into the window. The LED 720, held by the holder 721 and attached to the unit body 724, is in close contact with the thermal conductive sheet and is thermally connected to the unit body 724 via the thermal conductive sheet.

[0108] The lens unit 73 includes a lens, a lens holder, a cover 732, a rotor 733, etc. (see Figure 21). The lens is a Fresnel lens formed from a light-transmitting synthetic resin such as silicone resin, acrylic resin, or polycarbonate resin. The lens holder is formed in an annular shape from synthetic resin. The lens holder holds the lens by surrounding its periphery.

[0109] The cover 732 is formed in a disc shape from a translucent synthetic resin such as acrylic resin. The cover 732 is attached to the rotor 733 as described later. The cover 732 prevents insects from entering the rotor 733 by covering the front surface of the rotor 733 (see Figure 20). The rotor 733 has a cylindrical portion and an annular operating portion 734 provided at the front end of the cylindrical portion (see Figure 20). The lens and lens holder are housed inside the cylindrical portion.

[0110] The lens unit 73 is housed within the first main body portion 701 of the main body 70, as will be described later (see Figures 20 and 21). Here, the lens unit 73 moves in the front-rear direction within the cylindrical portion by operating the operating portion 734 to rotate the rotor 733. In other words, the lens unit 73 can adjust the illumination range of the light emitted from the LED 720 and focused by the lens by changing the relative distance between the LED 720 and the lens by operating the operating portion 734.

[0111] In the modified example 1, the power supply A2 has an AC / DC conversion block 74A and a DC conversion block 74B (see Figure 21).

[0112] The AC / DC conversion block 74A has an AC / DC conversion circuit that converts AC voltage (AC power) supplied from the power system via the lighting wiring duct and plug unit B22 to DC voltage (DC power). The AC / DC conversion circuit consists of a first printed circuit board 741 on which multiple circuit components are mounted on a double-sided printed circuit board. The AC / DC conversion block 74A further includes a first heat sink 743 to which the first printed circuit board 741 is attached, and a first heat conductive member 745 interposed between the first printed circuit board 741 and the first heat sink 743 (see Figure 21).

[0113] The DC conversion block 74B comprises a DC conversion circuit, a connection part 3, and a wireless communication device 2. The DC conversion circuit has a DC conversion circuit that converts (steps down) the DC voltage output from the AC / DC conversion block 74A to a DC voltage suitable for the LED 720. The DC conversion circuit is composed of a second printed circuit board 742 on which multiple circuit components are mounted on a double-sided printed circuit board. The connection part 3 is mounted on the second printed circuit board 742. Furthermore, the DC conversion block 74B also comprises a second heat sink 744 to which the second printed circuit board 742 is attached, and a second heat conductive member 746 interposed between the second printed circuit board 742 and the second heat sink 744 (see Figure 21).

[0114] The end cover 76 has a cover plate 760, a mounting portion 761, a first boss 764, and a second boss 765 (see Figure 21). The cover plate 760, the mounting portion 761, the first boss 764, and the second boss 765 are integrally formed from aluminum alloy die casting.

[0115] The mounting portion 761 is configured to rotatably attach the arm 75 to the end cover 76. Two screw holes 7610 are provided on the front surface of the mounting portion 761, spaced apart in the left-right direction (see Figure 21). That is, the AC / DC conversion block 74A is attached to the end cover 76 by screwing the first heat sink 743 into these two screw holes 7610. Furthermore, recesses 7611 are provided at both ends of the mounting portion 7611 in the left-right direction. One screw hole 7612 is provided on the bottom surface of each recess 7611 (see Figure 21).

[0116] The first boss 764 is formed in a roughly pyramidal truncated shape. The first boss 764 is integrally formed with the cover plate 760 so as to protrude forward from the lower end of the front surface of the cover plate 760. A screw hole 7640 is formed on the tip surface (front surface) of the first boss 764. The second boss 765 is formed in a roughly prismatic shape. The second boss 765 is integrally formed with the cover plate 760 so as to protrude forward from both sides of the first boss 764 at the lower end of the front surface of the cover plate 760. Two screw holes 7650 are provided on the tip surface (front surface) of the second boss 765. These two screw holes 7650 are located on the left and right sides of the first boss 764 when viewed from the front.

[0117] A DC conversion block 74B is attached to the second boss 765. In other words, two screws, one inserted into each of the screw insertion holes provided in the second heat sink 744, are then screwed into each of the two screw holes 7650, thereby fixing the second heat sink 744 to the end cover 76.

[0118] The end cover 76 is attached to the second main body 702 by being screwed into the screw hole 7640 of the first boss 764 and the two screw holes 7612 of the mounting portion 761.

[0119] However, in Modification 1, the power supply A2 is housed within the second main body 702, making it unlikely to be directly touched by a person. Therefore, the lighting device B2 in Modification 1 does not require the power supply A2 to be housed in a casing.

[0120] (2-3-2) Modification example 2 The lighting device B3 in the modified example 2 is a so-called downlight, which is installed on the ceiling, for example, by being embedded in a recessed hole provided in the ceiling.

[0121] The lighting device B3 of the modified example 2 comprises a lamp body 8 and a power supply device A3 (see Figure 22). 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 (not shown). The LED is positioned above 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.

[0122] In modified example 2, the power supply unit A3 comprises a power supply block 1, a wireless communication device 2, a connection part 3, and a metal housing 4. The housing 4 is formed in the shape of a rectangular parallelepiped. The power supply block 1, the wireless communication device 2, and the connection part 3 are housed within the housing 4. The housing 4 of the power supply unit A3 in modified example 2 is mounted on the upper part of the frame 80.

[0123] In the modified example 2, the lighting device B3 is installed on the ceiling by inserting the power supply A3 into the ceiling space through the recessed hole, and sandwiching the ceiling panel around the recessed hole between the periphery of the frame 80 and the three mounting springs 82.

[0124] However, the lighting device B3 of the modified example, like the lighting device B1 according to the embodiment, can improve the reliability of the electrical connection between the power supply block 1 and the wireless communication device 2.

[0125] (3) Summary A power supply device (A1; A2; A3) according to a first aspect of the present disclosure comprises a power supply block (1) that supplies power to a load, a wireless communication device (2) that performs wireless communication, and a restricting member (recess 101, protrusion 25). The power supply block (1) has a plate-shaped power supply board (10) on which circuit components (11) are mounted on its surface, and a connection part (3) provided on the power supply board (10) that is electrically connected to the wireless communication device (2). The connection part (3) is configured so that the wireless communication device (2) can be inserted into and removed electrically. The restricting member restricts the wireless communication device (2), which is electrically connected to the connection part (3), from moving in the direction (first direction D1) that will cause it to detach from the connection part (3).
