Hereinafter, lighting devices and lighting fixtures according to embodiments of the present disclosure will be described in detail with reference to the drawings. However, each figure 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 size ratios. Note that the configuration described in the embodiments below is only an example of the present disclosure. The present disclosure is not limited to the following embodiments, and various changes can be made depending on the design etc. as long as the effects of the present disclosure can be achieved.

The mounting member 4 has a signal passage section X1 through which electromagnetic waves can pass electromagnetically. In this embodiment, "electromagnetic waves can pass through electromagnetically" includes not only a state in which electromagnetic waves are not reflected or absorbed, but also a state in which a part of electromagnetic waves is reflected or absorbed.

In the conventional example, a wireless communication unit case that accommodates a wireless communication unit and a case that accommodates a lighting circuit have completely independent structures. Therefore, it is necessary to separately attach the lighting circuit and the wireless communication unit to the sheet metal of the lighting fixture, which takes time and effort to assemble the lighting fixture (lighting device).

As a result, the lighting device (light source unit A1) according to the embodiment can improve the workability of assembly work compared to the conventional example. Moreover, in the lighting device (light source unit A1) according to the embodiment, since the mounting member 4 has the signal passage section X1 through which electromagnetic waves can pass electromagnetically, the radio signal received or transmitted by the radio communication section 3 is attenuated. can be suppressed.

Furthermore, the lighting fixture B1 according to the embodiment includes a lighting device (light source unit A1) and a fixture body 9 that supports the lighting device (light source unit A1) (see FIGS. 1 and 2).

Therefore, the lighting fixture B1 according to the embodiment can improve the workability of the assembly work compared to the conventional example.

(2) Details (2-1) Lighting fixture First, lighting fixture B1 (hereinafter abbreviated as lighting fixture B1) according to the embodiment will be described.

As shown in FIGS. 1 and 2, the lighting fixture B1 includes a lighting device according to the embodiment, that is, a light source unit A1 (hereinafter abbreviated as light source unit A1) and a fixture body 9 that supports the light source unit A1. Be prepared. The light source unit A1 is removably attached to a fixture body 9 that is directly attached to the ceiling. However, the appliance main body 9 may be embedded in the ceiling. Alternatively, the instrument body 9 may be directly attached to the wall or embedded in the wall.

The device main body 9 includes a long box-shaped accommodating section 90 with an open bottom surface, a pair of reflective plates 91 that protrude obliquely upward from the opening edges on both sides along the longitudinal direction of the accommodating section 90, and and a pair of end plates 92 provided at both longitudinal ends of the pair of reflection plates 91 (see FIG. 2). Note that the housing portion 90 and the pair of reflective plates 91 are integrally formed by punching and bending a metal plate.

In the instrument body 9, hanging bolts (not shown) are inserted into at least any two of the plurality of attachment holes 900 provided on the bottom surface of the housing part 90, and nuts (not shown) are inserted into the hanging bolts. (not shown) is tightened to install it on the ceiling. Further, a power supply wire is inserted into any one of the plurality of power supply holes 901 provided on the bottom surface of the accommodating portion 90 . However, when a plurality of lighting fixtures B1 are installed, another power supply line for feed wiring may be inserted into another power supply hole 901.

A terminal block 902 is attached to the bottom surface of the housing section 90. Terminal block 902 is electrically connected to power cable 903. A power connector 904 is provided at the tip of the power cable 903.

Thus, the power wire inserted into the power hole 901 of the main body 9 is electrically connected to the terminal block 902, and is connected to the power supply device 2 of the light source unit A1 via the terminal block 902, the power cable 903, and the power connector 904. (Specifically, it is electrically connected to a power terminal section 22 described later).

(2-2) Light Source Unit The light source unit A1 includes an LED module 1, a power supply device 2, a wireless communication section 3, a mounting member 4, and a cover 7 (see FIG. 2).

(2-2-1) LED Module The LED module 1 includes a large number of LEDs 10 and a substrate 11. The substrate 11 is formed into a long rectangular plate shape. A large number of LEDs 10 are mounted in the center of the front surface (lower surface) of the board 11 in the lateral direction, and arranged in a row at regular intervals along the longitudinal direction of the board 11 (see FIG. 2).

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

(2-2-3) Cover The cover 7 is formed into a semi-cylindrical shape using a transparent synthetic resin such as acrylic resin or polycarbonate resin (see FIG. 2). Moreover, the cover 7 has a pair of projecting walls 70 that protrude upward along the longitudinal direction. The cover 7 accommodates the mounting member 4 between a pair of projecting walls 70, and has hooks formed at the tips (upper ends) of the pair of side plates 41 of the mounting member 4 at the tips (upper ends) of the pair of projecting walls 70. It is attached to the attachment member 4 by being hooked on. Note that the cover 7 may be formed of inorganic glass such as quartz glass.

(2-2-4) Power Supply Device The power supply device 2 includes a lighting circuit 21 and a case 20 that accommodates the lighting circuit 21 (see FIG. 2).

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

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

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

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

Control circuit 212 includes, for example, a microcontroller. The control circuit 212 controls the power conversion circuit 210 to maintain the output voltage of the power conversion circuit 210 at a constant DC voltage. Further, the control circuit 212 controls the step-down chopper circuit of the constant current circuit 211 so that the DC current supplied from the constant current circuit 211 to the LED module 1 matches the target value. Note that the control circuit 212 changes the target value of the DC current supplied to the LED module 1 according to the dimming signal received from the wireless communication unit 3 via the signal connector 5.

Here, the power terminal section 22 is mounted on one end of the printed wiring board 25 in the longitudinal direction (see FIGS. 2 and 5). Note that the power terminal section 22 in the embodiment is a connector to which the power connector 904 is removably connected, but a terminal block to which a conductor of an electric wire is electrically connected may be used instead of the power connector 904. Alternatively, the power terminal portion may be a lead wire drawn out from the lighting circuit 21 and may be connected to the conductor of the power cable 903 by soldering. Note that the configuration of the power terminal section 22 includes configurations other than those described above. Further, a socket 50 of the signal connector 5 is mounted on the other longitudinal end of the printed wiring board 25 (see FIG. 5). However, in FIGS. 4 and 5, circuit components mounted on the front surface (lower surface) and the back surface (upper surface) of the printed wiring board 25 are omitted.

The case 20 has a rectangular bottom wall 200 and a pair of first side walls 201 that protrude downward from both longitudinal ends of the bottom wall 200 along the lateral direction of the bottom wall 200 . Furthermore, the case 20 has a pair of second side walls 202 that protrude downward from both ends of the bottom wall 200 in the longitudinal direction along the longitudinal direction of the bottom wall 200 (see FIGS. 4 and 5). That is, the case 20 is formed into an elongated box shape with an opening 204 in the front (downward) of the bottom wall 200. Furthermore, the case 20 has a fixing piece 203 that projects outward from the tip of one of the second side walls 202 (see FIG. 4). The fixing piece 203 is formed into a square gutter shape.

The case 20 accommodates a printed wiring board 25 of the lighting circuit 21 and a printed wiring board 32 of a wireless circuit section 30, which will be described later, arranged in the longitudinal direction (see FIG. 5). The case 20 has a plurality of claws 205 cut and raised from a pair of second side walls 202 (see FIG. 5). Case 20 supports two printed wiring boards 25 and 32 sandwiched between these plurality of claws 205 . Note that the insertion port of the power terminal portion 22 projects out of the case 20 through a window hole provided in one first side wall 201 (see FIG. 5).

The power supply device 2 is attached to the upper surface (second surface 40B) of the attachment member 4 of the light source unit A1 so that the opening 204 of the case 20 faces the attachment member 4 (see FIGS. 2 and 5). Specifically, the case 20 is fixed to the mounting member 4 by screwing one of the second side walls 202 and the fixing piece 203 to each side plate 41 of the mounting member 4 . Moreover, in the state attached to the attachment member 4, the opening 204 of the case 20 is closed by the bottom plate 40 of the attachment member 4 (see FIGS. 4 and 5).

(2-2-5) Wireless Communication Unit The wireless communication unit 3 includes a wireless circuit unit 30 and an antenna unit 31 (see FIG. 3). The wireless circuit section 30 includes a printed wiring board 32 in which a wiring conductor is printed on a rectangular insulating substrate, and circuit components 33 mounted on the printed wiring board 32 (see FIG. 2). In other words, the wireless circuit section 30 is composed of a printed circuit. Note that a plug 51 of the signal connector 5 is mounted on the end of the printed wiring board 32 (see FIGS. 4 and 5). The plug 51 is mechanically and electrically connected to a socket 50 mounted on the printed wiring board 25 of the lighting circuit 21 . Note that the shape of the printed wiring board 25 is not limited to a quadrilateral, and includes various shapes such as a polygon other than a quadrangle, a circle, and the like.

The antenna section 31 is configured to emit electromagnetic waves (for example, radio waves in the 920 MHz band or 2.4 GHz band) into space, and to receive electromagnetic waves from space. The antenna section 31 is, for example, a so-called pattern antenna formed of a conductor printed on a printed wiring board 32. However, the antenna section 31 may be formed on a printed wiring board independent from the printed wiring board 32 of the wireless circuit section 30. Further, the antenna section 31 is not limited to a pattern antenna, and may be a patch antenna (microstrip antenna), a chip antenna, a rod antenna, a film antenna, or the like.

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

The lighting circuit 21 causes the LED module 1 to blink (switch between on and off) by changing the target value of the DC current that the control circuit 212 supplies to the LED module 1 in accordance with the dimming signal received from the wireless communication unit 3. ) and dimming.

As described above, the wireless communication unit 3 is housed in the case 20 of the power supply device 2 together with the lighting circuit 21. Here, the wireless signal transmitted from the remote control can reach the antenna section 31 through the opening 204 of the case 20 that opens downward. Therefore, the light source unit A1 can suppress attenuation of the radio signal reaching the antenna section 31 even when the case 20 is made of metal.

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

First, a power line drawn out from the ceiling is drawn into the accommodating portion 90 through the power hole 901 of the appliance body 9, and then the appliance body 9 is attached to a hanging bolt provided on the ceiling. Then, the power line drawn through the power hole 901 is electrically connected to the terminal block 902.

Next, after the power connector 904 of the power cable 903 is plugged and connected to the power terminal section 22 of the power supply device 2, the light source unit A1 is attached to the fixture main body 9 so that the power supply device 2 is housed in the housing section 90. . Note that the mounting structure of the light source unit A1 to the instrument body 9 is conventionally well known, so detailed explanation and illustration thereof will be omitted.

The lighting fixture B1 is installed on the ceiling by the above procedure.

Here, the case 20 of the power supply device 2 houses a power terminal section 22, a lighting circuit 21, and a wireless circuit section 30 arranged in this order. Therefore, when the light source unit A1 is attached to the instrument body 9, the power terminal section 22 can be placed near the terminal block 902 attached to the housing section 90 of the instrument body 9 (see FIG. 6). . Therefore, the light source unit A1 can shorten the power cable 903. Further, the case 20 is arranged between the plurality of attachment holes 900 provided in the housing part 90 (see FIG. 6). Therefore, in the light source unit A1, the distance between the hanging bolt inserted into the mounting hole 900 of the instrument main body 9 and the case 20 can be sufficiently spaced (see FIG. 6). As a result, the light source unit A1 can provide a sufficient insulation distance between the hanging bolt and the case 20.

(2-4) Operation of the lighting fixture The power supply line connected to the terminal block 902 of the fixture body 9 is turned on and off by, for example, a switch installed on the wall of the room (hereinafter referred to as a wall switch). . In other words, the lighting fixture B1 (light source unit A1) is alternately switched between a lit state and an unlit state by operating the wall switch.

In addition, when the lighting fixture B1 (light source unit A1) is energized via a wall switch, blinking and dimming are remotely controlled by a wireless signal transmitted from a remote controller (hereinafter referred to as a remote controller) not shown. is possible.

For example, the remote control receives an operation input from a person and generates control information corresponding to the received operation input. Furthermore, the remote control transmits a wireless signal containing the generated control information. The control information generated by the remote controller includes an instruction to turn on and off the lighting fixture B1 (light source unit A1), an instruction to change the dimming level, and the like.

A wireless signal transmitted from the remote control is received by the wireless communication section 3 of the light source unit A1. The wireless communication unit 3 converts the control information included in the wireless signal into a dimming signal, and transmits the converted dimming signal to the lighting circuit 21 (control circuit 212) via the signal connector 5. Note that the dimming signal corresponds to an arbitrary value from 0% to 100%, for example, assuming that the light amount at the time of rated lighting of the light source unit A1 is 100%. However, when the control information is an instruction to switch from off to on, the dimming signal is set to 100%, and when the control information is an instruction to switch from on to off, the dimming signal is set to 0%.

The lighting circuit 21 causes the LED module 1 to blink (switch between on and off) by changing the target value of the DC current that the control circuit 212 supplies to the LED module 1 in accordance with the dimming signal received from the wireless communication unit 3. ) and dimming. Note that when the dimming signal is set to 0%, the control circuit 212 turns off the LED module 1 by stopping the power conversion circuit 210 and the constant current circuit 211.

Here, a part of the wireless signal (radio wave) transmitted from the remote control, for example, electromagnetically passes through the gap between the first side wall 201 of the case 20 and the bottom plate 40 of the mounting member 4 (see FIG. 4) and transmits the wireless signal. The antenna section 31 of the communication section 3 is reached. Note that since the mounting member 4 of the light source unit A1 is formed of a metal material, the wireless signal (radio wave) that electromagnetically passes through the mounting member 4 and reaches the antenna section 31 is attenuated.

In particular, as shown in FIG. 4, when the distance D1 from the pattern forming surface of the antenna section 31 (lower surface of the printed wiring board 32) to the mounting member 4 (bottom plate 40) is short, the attenuation of the wireless signal (radio wave) increases. It has been known. Therefore, it is desirable that the distance D1 is, for example, 4 mm or more. However, the lower limit value of the distance D1 changes depending on the magnitude of the radio wave output of the antenna section 31, the frequency band of the radio waves, the type of material of the mounting member 4, the thickness of the mounting member 4, and the like.

Furthermore, the light source unit A1 has a signal passing section X1 on the mounting member 4 that can electromagnetically pass a wireless signal. The signal passing section X1 is, for example, a recess 43 formed in a part of the mounting member 4 (bottom plate 40), which exists in a position where electromagnetic waves (radio waves) emitted from the antenna section 31 can reach (see FIG. 7). ). In other words, the amount of attenuation when a radio signal (radio wave) electromagnetically passes through the recess 43 (signal passage section It is less than the amount of attenuation when passing electromagnetically. Therefore, the light source unit A1 aims to suppress the attenuation of the wireless signal electromagnetically passing through the mounting member 4 by forming the signal passage portion X1 (recess 43) in a part of the mounting member 4 (bottom plate 40). be able to.

Alternatively, the signal passage section X1 may be an opening 44 formed in a part (bottom plate 40) of the mounting member 4 (see FIG. 8). The opening 44 penetrates the bottom plate 40 in the thickness direction (vertical direction). Further, the opening 44 is preferably formed in the bottom plate 40 of the mounting member 4 at a position where electromagnetic waves (radio waves) emitted from the antenna section 31 can reach. Therefore, the light source unit A1 further suppresses the attenuation of the wireless signal electromagnetically passing through the mounting member 4 by forming the opening 44 (signal passage section X1) in a part of the mounting member 4 (bottom plate 40). can be achieved. Note that if the recess 43 or the opening 44 is formed in the mounting member 4 (bottom plate 40), the radio waves will not be limited even if the lower limit of the distance D1 is shorter than when the recess 43 and the opening 44 are not formed. It may be possible to suppress it. However, there is a risk that foreign matter (dust, insects, etc.) may enter the space surrounded by the cover 7 and the mounting member 4 through the opening 44 of the bottom plate 40. Therefore, it is preferable to cover the opening 44 with a lid 45 made of a material that does not easily attenuate radio waves (eg, synthetic resin) (see FIG. 8). By closing the opening 44 with the lid 45, the light source unit A1 can suppress the attenuation of radio waves and prevent foreign matter from entering. Note that the opening 44 may be closed with a member other than the lid 45, such as an electrically insulating adhesive sheet.

Further, the signal passage portion X1 may be an opening 410 formed in the side plate 41 of the mounting member 4 (see FIG. 9). The opening 410 (signal passage section X1) is preferably provided at a position where electromagnetic waves (radio waves) emitted from the antenna section 31 can reach. Further, the opening 410 is preferably closed with a lid 411 made of a material that does not easily attenuate radio waves, such as synthetic resin, an adhesive sheet having electrical insulation properties, or the like (see FIG. 9). Note that an opening 206 may be formed in the second side wall 202 of the case 20 located between the wireless communication section 3 (particularly the antenna section 31) and the signal passage section X1 (see FIG. 9).

(3) Modifications Next, some modifications of the light source unit A1 according to the embodiment will be described. However, each modification described below is characterized by the configuration of the power supply device 2 and the wireless communication unit 3 (especially the structure of the case 20, the arrangement of the wireless communication unit 3 in the case 20, etc.), and other configurations are not implemented. This is common to the light source unit A1 according to the embodiment. Therefore, in the description of each modification, illustration and description of the configuration common to the light source unit A1 according to the embodiment will be omitted.

(3-1) Modification example 1
The light source unit A1 of Modification 1 is characterized in that the printed wiring board 25 of the lighting circuit 21 and the printed wiring board 32 of the wireless circuit section 30 are housed in the case 20 with their orientations crossed (as shown in FIG. 10A and FIG. 10B). Note that the directions of the printed wiring board 25 and the printed wiring board 32 refer to the normal direction of the mounting surfaces of the printed wiring boards 25 and 32, respectively. Specifically, the lighting circuit 21 is housed in the case 20 so that the bottom wall 200 and the printed wiring board 25 are almost parallel, and the wireless circuit section 30 is housed so that the second side wall 202 and the printed wiring board 32 are almost parallel. (Wireless communication unit 3) is housed in case 20. Further, the printed wiring board 25 and the printed wiring board 32 are housed in the case 20 side by side along the longitudinal direction of the case 20. Note that the printed wiring board 25 of the lighting circuit 21 and the printed wiring board 32 of the wireless circuit section 30 are each held by claws 205 provided on the first side wall 201 of the case 20. Note that the lighting circuit 21 and the wireless circuit section 30 are electrically connected by a lead wire 52 (see FIG. 10A).

Therefore, in the light source unit A1 of Modification 1, the printed wiring boards 25 and 32 are housed in the case 20, compared to the case where the two printed wiring boards 25 and 32 are housed in the case 20 with their orientations not intersecting as in the embodiment. It is possible to improve the work efficiency of the work carried out in the 20. Further, when the antenna section 31 is a pattern antenna or a patch antenna, the antenna section 31 has directivity in the thickness direction of the printed wiring board 32. Therefore, by housing the light source unit A1 of Modification 1 in the case 20 with the printed wiring board 32 in an upright position, it is possible to improve the reception sensitivity in the horizontal direction for wireless signals. Although not shown, the signal passing portion X1 is provided on at least one of the bottom plate 40 and the side plate 41 of the mounting member 4.

Here, if the distance D2 (see FIG. 10A) from the printed wiring board 32 to the mounting member 4 (bottom plate 40) is short, the attenuation of radio waves when electromagnetically passing through the mounting member 4 will increase. Therefore, it is desirable that the distance D2 is, for example, 1 mm or more. However, the lower limit value of the distance D2 changes depending on the magnitude of the radio wave output of the antenna section 31, the frequency band of the radio waves, the type of material of the mounting member 4, the thickness of the mounting member 4, and the like.

Note that the wireless communication unit 3 may be housed in the case 20 so that the first side wall 201 and the printed wiring board 32 are substantially parallel (see FIG. 10B). Printed wiring board 32 is held by claws 205 provided on bottom wall 200.

(3-2) Modification example 2
The light source unit A1 of the second modification is different from the first modification in that the printed wiring board 25 of the lighting circuit 21 and the printed wiring board 32 of the wireless circuit section 30 are arranged in the height direction (up and down direction) of the case 20 and housed in the case 20. The light source unit A1 is different from the light source unit A1 (see FIGS. 11A and 11B). In other words, the light source unit A1 of the second modification has the lighting circuit 21 and A feature is that the wireless communication section 3 is housed in a case 20. In the embodiment, "overlapping" means that a part or all of the printed wiring board 32 of the wireless circuit section 30 exists within the projection range of the printed wiring board 25 of the lighting circuit 21 when viewed from above and below. It means that.

The printed wiring board 25 of the lighting circuit 21 is held by claws 205 provided on the first side wall 201 of the case 20 . On the other hand, the printed wiring board 32 of the wireless circuit section 30 (wireless communication section 3) is electrically and mechanically connected to the printed wiring board 25 by the signal connector 5, so that the printed wiring board 32 is connected to the case 20 via the printed wiring board 25. is maintained. However, the method of fixing printed wiring board 25 to case 20 is not limited to holding with claws 205. For example, the printed wiring board 25 may be screwed to a boss (bridge) protruding from the bottom wall 200 of the case 20. Alternatively, the printed wiring board 32 of the wireless circuit section 30 may be held in the case 20 and the printed wiring board 25 of the lighting circuit 21 may be held in the case 20 via the printed wiring board 32. Alternatively, the two printed wiring boards 25 and 32 may be held independently in the case 20.

Therefore, similarly to the first modification, the light source unit A1 of the second modification also aims to improve the workability of accommodating the printed wiring boards 25 and 32 in the case 20, and to improve the reception sensitivity in the horizontal direction for wireless signals. be able to. Although not shown, the signal passing portion X1 is provided on at least one of the bottom plate 40 and the side plate 41 of the mounting member 4.

Note that, as shown in FIG. 11B, the distance D2 from the printed wiring board 32 of the antenna section 31 to the mounting member 4 (bottom plate 40) is preferably 1 mm or more in order to suppress attenuation of wireless signals (radio waves). However, as long as the signal passing portion is provided on the bottom plate 40, it may be less than 1 mm. Similarly, it is desirable that the distance D3 from the printed wiring board 32 to the bottom wall 200 of the case 20 is also 1 mm or more. Furthermore, it is desirable that the distance D4 from the printed wiring board 32 to the first side wall 201 of the case 20 and the distance D5 from the printed wiring board 32 to the second side wall 202 of the case 20 be 4 mm or more. However, if the first side wall 201 or the second side wall 202 is provided with a signal passage section, the distances D4 and D5 may be 4 mm or less. Furthermore, the lower limit value of the distances D2 to D5 changes depending on the magnitude of the radio wave output of the antenna section 31, the frequency band of the radio waves, the type of material of the mounting member 4, the thickness of the mounting member 4, and the like.

(3-3) Modification example 3
The light source unit A1 of Modification 3 differs from the light source unit A1 of Modification 2 in that the printed wiring board 32 of the wireless circuit section 30 is housed in the case 20 so as to face the first side wall 201 of the case 20 (FIG. 12). reference).

As in the case of modifications 1 and 2, the light source unit A1 of modification 3 also improves the workability of accommodating printed wiring boards 25 and 32 in case 20, and improves the reception sensitivity in the horizontal direction for wireless signals. can be achieved. Although not shown, the signal passing portion X1 is provided on at least one of the bottom plate 40 and the side plate 41 of the mounting member 4.

(3-4) Modification example 4
The light source unit A1 of Modification 4 is characterized in that the case 20 includes a support section 208 that supports the lighting circuit 21 and the wireless circuit section 30 (see FIGS. 13A and 13B).

The support portion 208 includes a horizontal piece 2080 formed in a flat plate shape and protruding into the case 20 from the second side wall 202 of the case 20, and a vertical piece 2081 formed in a flat plate shape and protruding upward from the tip of the horizontal piece 2080. , (see FIG. 13A). The support portion 208 may be cut and raised from the second side wall 202 and formed integrally with the case 20, for example. Alternatively, the support portion 208 may be formed of a synthetic resin molded body.

The horizontal piece 2080 of the support section 208 is arranged under the printed wiring board 32 of the wireless circuit section 30 and supports the printed wiring board 32 from below (see FIG. 13A). Further, the vertical piece 2081 faces the printed wiring board 32 along the thickness direction of the printed wiring board 32, and regulates the inclination of the printed wiring board 32.

Furthermore, when the support part 208 is formed of a synthetic resin molded body, the support part 208 has a fixing piece 2082 that projects upward from the rear end of the horizontal piece 2080, and the fixing piece 2082 is fixed to the second side wall 202. I don't care if it happens. If the support part 208 is formed of a synthetic resin molded body having electrical insulation properties, the support part 208 can electrically insulate between the wireless circuit part 30 and the second side wall 202 of the case 20 . However, if the distance between the lower end of the printed wiring board 32 and the second surface 40B of the bottom plate 40 of the mounting member 4 is short (for example, about 1 mm), the bottom plate 40 can be used instead of the support part 208 to prevent the wireless communication part 3 from falling. But it doesn't matter.

Thus, in the light source unit A1 of the fourth modification, by supporting the printed wiring board 32 (wireless circuit section 30) on the support section 208, it is possible to prevent the plug 51 and the socket 50 from becoming disconnected. In addition, excessive stress is applied to the solder joints between the printed wiring board 25 and the socket 50 and the solder joints between the printed wiring board 32 and the plug 51 due to vibrations during transportation, which accelerates the deterioration of these solder joints. There is a risk. However, since the case 20 includes the support section 208 that supports the lighting circuit 21 and the wireless circuit section 30, it is possible to prevent the solder joint from deteriorating due to vibrations of the lighting circuit 21 and the wireless circuit section 30. Note that the signal passing portion X1 is provided, for example, on the bottom plate 40 of the mounting member 4.

(3-5) Modification example 5
In the light source unit A1 of modification 5, the power supply device 2 has an insulator 24 made of an electrically insulating material, and the insulator 24 is arranged between the lighting circuit 21 and the wireless circuit section 30 in the case 20. It is characterized by the fact that (see Figure 14).

The insulator 24 is made of, for example, a synthetic resin material and has a flat plate shape. The insulator 24 is arranged between the printed wiring board 25 of the lighting circuit 21 and the printed wiring board 32 of the wireless circuit section 30 so as to be parallel to the pair of first side walls 201 .

Therefore, in the light source unit A1 of the fifth modification, the insulation distance between the lighting circuit 21 and the wireless circuit section 30 can be increased by the insulator 24. As a result, the light source unit A1 of the fifth modification can suppress short-circuit failures between the lighting circuit 21 and the wireless circuit section 30 and malfunctions due to noise in the lighting circuit 21 and the wireless circuit section 30.

Note that a groove or a hole may be provided in a part of the insulator 24. Alternatively, the insulator 24 may be formed into a box shape, and the wireless communication section 3 may be housed inside.

(3-6) Modification example 6
The light source unit A1 of modification 6 is characterized in that the wireless communication section 3 has a plurality of antenna sections 31 (see FIG. 15). The wireless communication unit 3 in the sixth modification includes an antenna unit (hereinafter referred to as a first antenna unit 31A) formed on the printed wiring board 32 of the wireless circuit unit 30, and a board ( (hereinafter referred to as the antenna substrate 34) (hereinafter referred to as the second antenna part 31B).

Here, it is preferable that the direction in which the reception sensitivity of the first antenna section 31A peaks and the direction in which the reception sensitivity of the second antenna section 31B peaks are shifted by about 90 degrees from each other. Thereby, the light source unit A1 of the sixth modification can expand the range in which the wireless communication section 3 can receive electromagnetic waves (radio waves). Note that the mounting member 4 may be provided with two signal passing sections X1 corresponding one-to-one to the two antenna sections 31A and 31B, or one signal passing section X1 corresponding to the two antenna sections 31A and 31B. X1 may be provided.

Further, the first antenna section 31A and the second antenna section 31B may be configured to emit radio waves in different frequency bands into space or to receive radio waves from space.

Furthermore, the wireless circuit section 30 and the first and second antenna sections 31A and 31B may be formed on the printed wiring board 25 of the lighting circuit 21. That is, the lighting circuit 21 and the wireless communication section 3 may be formed on the same substrate (one printed wiring board 25). In the light source unit A1, the lighting circuit 21 and the wireless communication section 3 are formed on the same substrate, so that the power supply device 2 can be downsized.

Note that the second antenna section 31B may be configured to emit or receive electromagnetic waves other than radio waves, such as infrared light or visible light, into space. In this case, the second antenna section 31B includes a photoelectric conversion element that converts infrared light or visible light into an electrical signal, or a light emitting element that converts an electrical signal into infrared light or visible light. Therefore, the light source unit A1 of the sixth modification can perform communication using different types of electromagnetic waves (for example, radio waves and infrared light or visible light) as a medium.

(3-7) Modification example 7
The light source unit A1 of modification 7 is characterized by the arrangement of the lighting circuit 21 and the wireless communication section 3 within the case 20. In the light source unit A1 of modification 7, a rectangular space 250 is formed in the center of the printed wiring board 25 of the lighting circuit 21, and the printed wiring board 32 of the wireless circuit section 30 is arranged within the space 250. (See Figure 16).

The light source unit A1 of Modification 7 can effectively utilize the space within the case 20 to reduce the size of the case 20.

(3-8) Other Modifications The printed wiring board 25 of the lighting circuit 21 and the printed wiring board 32 of the wireless communication section 3 are housed in the case 20 while being separated from each other in the height direction (vertical direction) of the case 20. I don't mind. (See Figure 17A). At this time, it is preferable that the printed wiring board 32 of the wireless communication unit 3 be arranged at a position closer to the opening 204 of the case 20 than the printed wiring board 25 of the lighting circuit 21 in the height direction of the case 20. By arranging the wireless communication unit 3 (particularly the antenna unit 31) near the opening 204 of the case 20, it is possible to reduce attenuation of wireless signals. However, the printed wiring board 25 of the lighting circuit 21 may be placed near the opening 204 of the case 20 (see FIG. 17B). In this case, the length of a conductor (for example, an electric wire) that electrically connects the lighting circuit 21 and the wireless communication unit 3 can be shortened, and noise resistance can be improved.

Further, the printed wiring board 25 of the lighting circuit 21 is completely connected to the printed wiring board 32 of the wireless communication unit 3 when viewed from the height direction of the case 20 (the direction facing the second surface 40B of the bottom plate 40 of the mounting member 4). They may be accommodated in the case 20 so that they overlap (see FIG. 17C). If the printed wiring board 32 of the wireless communication unit 3 is housed in the case 20 so as to overlap the printed wiring board 25 of the lighting circuit 21 in this manner, the longitudinal dimension of the case 20 can be shortened. However, the printed wiring board 25 of the lighting circuit 21 may be housed in the case 20 so as to partially overlap the printed wiring board 32 of the wireless communication section 3 (see FIG. 17D).

The connection member that connects the lighting circuit 21 and the wireless circuit section 30 is not limited to the signal connector 5, but may be a harness cable in which a plurality of electric wires are bundled together. Further, the signal connector 5 is not limited to a structure in which it is inserted into and removed from the surfaces of the printed wiring boards 25 and 32 from both directions, but may be inserted into and removed from the printed wiring boards 25 and 32 from the thickness direction.

Furthermore, each of the printed wiring boards 25 and 32 may be fixed to the case 20 by being screwed to a plurality of bosses protruding from the bottom wall 200 of the case 20, for example.

Note that the wireless communication unit 3 may not only receive a wireless signal containing information related to lighting control of the LED module 1, but may also receive and transmit a wireless signal containing other information.

For example, the wireless communication section 3 may transmit a wireless signal including information regarding the usage status of the light source unit A1. Information regarding the usage status of the light source unit A1 includes, for example, the time (date) when usage started, cumulative lighting time, occurrence of an abnormality in the power supply device 2 or the LED module 1, and diagnosis of the lifespan of the power supply device 2 or the LED module 1. The results include the time period the lights were on, power consumption, etc. Alternatively, the wireless communication section 3 may transmit a wireless signal including detection information of a sensor provided in the light source unit A1 or the appliance main body 9. The sensor detection information includes, for example, detection information about the presence or absence of a person by a human sensor, detection information about brightness (illuminance) by a brightness sensor, and the like. Alternatively, the wireless communication section 3 may transmit a wireless signal including identification information of the light source unit A1. The identification information of the light source unit A1 includes a manufacturing lot number of the light source unit A1, a model number corresponding to the type of the light source unit A1, and the like.

The various types of information described above (information other than information related to lighting control) may be used for interlocking the lighting fixture B1 with other devices. Other devices that are linked with the lighting fixture B1 include, for example, television receivers, audio devices such as wireless speakers or smart speakers, air conditioning and air quality devices such as air conditioners and air purifiers, security devices, disaster prevention devices, etc. be.
