Moreover, in the lighting device (light source unit A1) according to the embodiment, at least a portion of the antenna section 31 is outside the case 20, so compared to a case where the entire antenna section 31 is inside the case 20, the antenna section 31 is It is possible to suppress the attenuation of electromagnetic waves emitted into space by the antenna section 31 or electromagnetic waves received from space by the antenna section 31.

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 a so-called pattern antenna formed of a conductor printed on a substrate different from the printed wiring board 32 (hereinafter referred to as an antenna substrate 310). Although it is preferable that the antenna board 310 is housed in a housing that is a box made of synthetic resin, the antenna board 310 may be left exposed without being housed in the housing. Further, the antenna section 31 is electrically connected to the wireless circuit section 30 via an electric wire (not shown). However, the antenna section 31 may be formed on the substrate 11 of the LED module 1. Note that 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 antenna section 31 (its housing) is attached to the outer surface of the second side wall 202 of the case 20. The second side wall 202 is provided with a pair of claws 205 that protrude outward. The antenna section 31 is attached to the second side wall 202 of the case 20 by sandwiching the antenna board 310 between the pair of claws 205 (see FIG. 4). However, the antenna section 31 may be attached to a portion other than the case 20, for example, the bottom plate 40 or the side plate 41 of the mounting member 4.

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 circuit unit 30 of the wireless communication unit 3 is housed in the case 20 of the power supply device 2 together with the lighting circuit 21. On the other hand, the antenna section 31 of the wireless communication section 3 is located outside the case 20. 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, 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, it is known that when the distance from the pattern forming surface of the antenna section 31 (lower surface of the antenna substrate 310) to the mounting member 4 (bottom plate 40) is short, attenuation of radio signals (radio waves) increases. Therefore, it is desirable that the distance is, for example, 4 mm or more. However, the lower limit of the above distance 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, it is preferable to form a recess 43 in a part (bottom plate 40) of the mounting member 4 that exists in a position where the electromagnetic waves (radio waves) emitted from the antenna part 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 of the mounting member 4 is the same as when it electromagnetically passes through a portion of the bottom plate 40 of the mounting member 4 where the recess 43 is not formed. less than the amount of attenuation. Therefore, in the light source unit A1, by forming the recess 43 in a part of the mounting member 4 (bottom plate 40), it is possible to suppress attenuation of the wireless signal that electromagnetically passes through the mounting member 4.

Alternatively, instead of the recess 43, an opening 44 may be formed in a part of the mounting member 4 (bottom plate 40) (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, in the light source unit A1, by forming the opening 44 in a part of the mounting member 4 (bottom plate 40), it is possible to further suppress attenuation of the wireless signal that electromagnetically passes through the mounting member 4. Note that if the recess 43 or opening 44 is formed in the mounting member 4 (bottom plate 40), the limitation of radio waves can be suppressed even if the lower limit of the distance is shorter than when the recess 43 and opening 44 are not formed. There are cases where it is possible. 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, an opening 410 may be formed in the side plate 41 of the mounting member 4 (see FIG. 9). The opening 410 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 covered 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.

(3) Modifications Next, some modifications of the light source unit A1 according to the embodiment will be described. However, each modified example described below is characterized by the configurations of the power supply device 2 and the wireless communication section 3, and the other configurations are 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 the first modification is housed in the case 20 with the printed wiring board 25 of the lighting circuit 21 and the printed wiring board 32 of the wireless circuit section 30 crossing each other, and the antenna section 31 is arranged in the wireless circuit section. It is characterized in that it is provided on the printed wiring board 32 of No. 30 (see FIGS. 10A and 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.

The printed wiring board 32 is formed into a rectangular flat plate shape, and the wireless circuit section 30 and the antenna section 31 are provided so as to be lined up in the longitudinal direction. The printed wiring board 32 is held by the claws 205 of the case 20 with the wireless circuit section 30 housed in the case 20 and the antenna section 31 protruding from the opening 204 to the outside of the case 20 .

(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).

Note that the antenna section 31 may be formed separately from the radio circuit section 30, or, similarly to the first modification, the antenna section 31 may be provided on the printed wiring board 32 of the radio circuit section 30.

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.

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.

The first antenna section 31A is a patch antenna formed on a substrate different from the printed wiring board 32 of the wireless circuit section 30 (hereinafter referred to as a first antenna substrate 310A). Further, the second antenna section 31B is a patch antenna formed on a substrate different from the first antenna substrate 310A (hereinafter referred to as a second antenna substrate 310B).

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.
