  The first signal wiring 5 connects the control circuit 42 and the first lighting circuit 31. The control circuit 42 transmits a first control signal to the first lighting circuit 31 via the first signal wiring 5.

  As described above with reference to FIG. 1, the lighting device 20 includes the first lighting unit 30 and the control unit 40. The lighting device 20 is outside the distribution board 4. Accordingly, the first lighting unit 30 and the control unit 40 are treated as one unit excluding the distribution board 4 and the installation location of the control unit 40 is determined without being affected by the installation location of the distribution board 4. It is possible. As a result, the first signal wiring 5 can be shortened.

[Second Embodiment]
With reference to FIG. 2, 2nd Embodiment of the illumination system 1 is described. FIG. 2 is a schematic configuration diagram of the second embodiment of the illumination system 1.

Accordingly, the first control signal is transmitted from the control circuit 42 to the first lighting circuit 31 on the third circuit board 50. As a result, the first signal wiring 5 becomes unnecessary, and the number of signal wirings used in the apparatus can be reduced.

  In addition, by mounting the first lighting power supply circuit 32 and the control power supply circuit 43 on a single third circuit board 50, power wiring for supplying power to the first lighting power supply circuit 32 and the control power supply circuit 43 is provided. The number can be reduced from two to one. In the second embodiment, for example, the first power wiring 6 is used and the second power wiring 7 is not used.

[Third Embodiment]
A third embodiment of the illumination system 1 will be described with reference to FIG. FIG. 3 is a schematic configuration diagram of a third embodiment of the illumination system 1. The third embodiment differs from the second embodiment in that the first lighting unit 30 and the control unit 40 share a power circuit. In the third embodiment, changes from the second embodiment will be mainly described.

  As shown in FIG. 3, in the lighting device 20, a power supply circuit that drives the first lighting unit 30 (first lighting power supply circuit 32) and a power supply circuit that drives the control unit 40 (control power supply circuit 43 shown in FIG. 2). ) Is also used as the other power circuit. That is, in the lighting device 20, a single power supply circuit supplies power to the first lighting circuit 31 and also supplies power to the control circuit 42. In the third embodiment, the first lighting power supply circuit 32 also serves as a power supply circuit (control power supply circuit 43 shown in FIG. 2) that drives the control unit 40. Therefore, the first lighting power supply circuit 32 supplies power to the first lighting circuit 31 and also supplies power to the control circuit 42.

  As described above with reference to FIG. 3, the single power supply circuit (first lighting power supply circuit 32) supplies power to the first lighting circuit 31 and also supplies power to the control circuit 42. Therefore, it is not necessary to provide a power circuit in each of the first lighting unit 30 and the control unit 40. As a result, the apparatus configuration can be simplified.

  Further, similarly to the second embodiment, the number of signal wirings and the number of power wirings used in the apparatus can be reduced. Further, by mounting the first lighting circuit 31, the control circuit 42, and the first lighting power supply circuit 32 on the single third circuit board 50, the entire circuit can be reduced in size and the apparatus can be reduced in size. Is possible.

[Fourth Embodiment]
A fourth embodiment of the illumination system 1 will be described with reference to FIG. FIG. 4 is a schematic configuration diagram of the fourth embodiment of the illumination system 1. The fourth embodiment is different from the first embodiment in that the first light source 11 is configured to be controlled by the control unit 40. In the fourth embodiment, changes from the first embodiment will be mainly described.

  As shown in FIG. 4, the illumination system 1 further includes a first switching unit (switching unit) 51 and a second switching unit 52. The first switching unit 51 is included in the lighting device 20. Each of the first switching unit 51 and the second switching unit 52 is manually operated. Each of the first switching unit 51 and the second switching unit 52 is, for example, a lever switch, a button switch, a slide switch, or a seesaw switch.

  The first switching unit 51 operates the control unit 40 to switch the control unit 40 between the operating state and the stopped state. Specifically, the first switching unit 51 operates the control power supply circuit 43 so that the control power supply circuit 43 supplies power to the control circuit 42 and the power supply stops. Switch to one of them. The 1st switching part 51 is provided in the lamp body of the lighting fixture 3, or the power supply unit of the lighting fixture 3, for example.

  The operation state of the control unit 40 indicates a state in which the control power supply circuit 43 supplies power to the control circuit 42. When the control unit 40 is in an operating state, the control unit 40 transmits a first control signal to the first lighting unit 30 to control the first lighting unit 30.

  The stop state of the control unit 40 indicates a state in which the supply of power from the control power supply circuit 43 to the control circuit 42 is stopped. When the control unit 40 is in a stopped state, the first control signal is not transmitted from the control unit 40. As a result, the control of the first lighting unit 30 by the control unit 40 is not performed.

  The 2nd switching part 52 operates the 1st lighting part 30, and switches the 1st light source 11 to either a lighting state and a light extinction state. Specifically, the second switching unit 52 operates the first lighting power supply circuit 32 so that the first lighting power supply circuit 32 supplies power to the first lighting circuit 31 and supplies power. Switch to one of the stopped states. The 2nd switching part 52 is provided in the wall of the building in which the lighting fixture 3 is installed, for example.

  The lighting state of the first light source 11 indicates a state where the first lighting power supply circuit 32 supplies power to the first lighting circuit 31. As a result, the first lighting circuit 31 supplies power to the first light source 11, and the first light source 11 is turned on.

  The extinguishing state of the first light source 11 indicates a state where the supply of power from the first lighting power supply circuit 32 to the first lighting circuit 31 is stopped. As a result, the first lighting circuit 31 does not supply power to the first light source 11, and the first light source 11 is turned off.

When the first switching unit 51 is operated so that the control unit 40 is in the operating state, the operation of the second switching unit 52 is enabled and the operation of the input unit 21 is enabled. Therefore, when the control unit 40 is in the operating state, the power supply from the first lighting unit 30 to the first light source 11 is cut off when the second switching unit 52 is switched from on to off. As a result, the first light source 11 is turned off while the control unit 40 remains in the operating state.
On the other hand, when the 1st switch part 51 is operated so that the control part 40 may be in a stop state, operation of the 2nd switch part 52 becomes effective. Accordingly, the first light source 11 is activated by the operation of the second switching unit 52. Specifically, the operation of the second switching unit 52 switches the first light source 11 between the lighting state and the extinguishing state. In this case, even if the input unit 21 is operated, the first light source 11 does not operate.

  As described above with reference to FIG. 4, the lighting device 20 includes the first switching unit 51 and the second switching unit 52. Therefore, according to the user's needs, it is possible to select whether the first light source 11 is operated by the input unit 21 or the first light source 11 is operated by the second switching unit 52. That is, a mode in which fine control of the first light source 11 such as dimming control and / or toning control is performed by the input unit 21 and simple control of the first light source 11 that is only turned off and on are performed by the second switching unit. It is possible to select one of the forms performed in 52.

[Fifth Embodiment]
With reference to FIG. 5, 5th Embodiment of the illumination system 1 is described. FIG. 5 is a schematic configuration diagram of the fifth embodiment of the illumination system 1. The fifth embodiment is different from the first embodiment in that the state of the control circuit 42 is notified. In the fifth embodiment, changes from the first embodiment will be mainly described.

  As shown in FIG. 5, the lighting device 20 includes a notification device 60. The notification device 60 includes a first detection unit 61, a second detection unit 62, and a notification unit 63. The first detection unit 61 detects the energization state of the control circuit 42. The energization state of the control circuit 42 indicates a state in which power is supplied from the control power supply circuit 43 to the control circuit 42. The second detection unit 62 detects the operating state of the control circuit 42. The operating state of the control circuit 42 indicates a state in which the control circuit 42 is transmitting the first control signal. The notification unit 63 receives an energization signal indicating the energization state of the control circuit 42 from the first detection unit 61. The notification unit 63 determines whether or not the control circuit 42 is in an energized state based on the energization signal. And the alerting | reporting part 63 alert | reports whether the control circuit 42 is an energization state. Further, the notification unit 63 receives an operation signal indicating the operation state of the control circuit 42 from the second detection unit 62. The notification unit 63 determines whether or not the control circuit 42 is in an operating state based on the operation signal. And the alerting | reporting part 63 alert | reports whether the control circuit 42 is an operation state.

  The notification unit 63 includes a display unit such as an LED indicator. Specifically, the notification unit 63 includes a first display unit for reporting the energization state of the control circuit 42 and a second display unit for reporting the operating state of the control circuit 42. When the control circuit 42 is energized, the first display unit is lit. When the control circuit 42 is not energized, the first display unit is turned off. Further, when the control circuit 42 is in an operating state, the second display unit is lit. When the control circuit 42 is not in the operating state, the second display unit is turned off. As a result, the user can recognize the energized state of the control circuit 42 and the operating state of the control circuit 42 by visually recognizing the notification unit 63. In addition, the alerting | reporting part 63 may have a single display part. In this case, the single display unit represents the state of the control circuit 42 by changing the mode of the lighting operation. For example, when the control circuit 42 is in an energized state and in an operating state, the display unit blinks. Further, when the control circuit 42 is in the energized state but not in the operating state, the display unit is continuously lit. Further, when the control circuit 42 is not in an energized state and not in an operating state, the display unit is turned off.

The installation place of the alerting | reporting part 63 is demonstrated.
The first light source 11 is provided, for example, on the ceiling of the irradiation chamber and irradiates light into the irradiation chamber. In this case, the alerting | reporting part 63 is installed in the place where the person who is in an irradiation room can visually recognize. For example, the notification unit 63 is attached to a support member of the first light source 11.

  Note that the notification unit 63 may be configured to notify either the energized state of the control circuit 42 or the operating state of the control circuit 42. However, it is advantageous that the notification unit 63 notifies both the energized state of the control circuit 42 and the operating state of the control circuit 42 in that the user can recognize the state of the control circuit 42 in more detail.

[Sixth Embodiment]
A sixth embodiment of the illumination system 1 will be described with reference to FIG. FIG. 6 is a schematic configuration diagram of a sixth embodiment of the illumination system 1.

The second lighting power supply circuit 72 converts AC power supplied from the distribution board 4 into DC power, and supplies the converted DC power to the second lighting circuit 71. The second lighting circuit 71 lights the second light source 12 with the power supplied from the second lighting power supply circuit 72.

The second signal wiring 8 connects the first lighting circuit 31 and the second lighting circuit 71.
The input unit 21 receives second information indicating the control content of the second light source 12. The second information is, for example, information indicating an instruction to turn on the second light source 12, information indicating brightness, information indicating color temperature, and information indicating an instruction to turn off.
The transmission unit 22 transmits the second information. The receiving unit 41 receives the second information. The control circuit 42 acquires the second information from the receiving unit 41.

The second control signal is transmitted to the second lighting circuit 71 via the second signal wiring 8.
The second lighting circuit 71 operates the second light source 12 based on the second control signal. As a result, the second light source 12 performs operations such as turning on / off, changing the brightness, and / or changing the color temperature in accordance with the contents defined in the second information.
Each of the 1st lighting part 30 and the 2nd lighting part 70 is provided with a terminal block. One end of the second signal wiring 8 is connected to the terminal block of the first lighting unit 30. The other end of the second signal wiring 8 is connected to the terminal block of the second lighting unit 70.

  As described above with reference to FIG. 6, a single control unit 40 can control a plurality of light sources. Therefore, it becomes possible to control a plurality of light sources efficiently. In addition, it is possible to simply configure the illumination system 1 that controls a plurality of light sources.

[Seventh Embodiment]
With reference to FIG.6 and FIG.7, 7th Embodiment of the illumination system 1 is described. FIG. 7 is a schematic diagram illustrating a usage state of the illumination system 1 according to the sixth embodiment.

  As shown in FIGS. 6 and 7, the lighting system 1 is installed in a building 100. The lighting fixture 3 and the slave lighting fixture 3a are installed on the ceiling of the building 100, for example. The distribution board 4 is installed on the wall of the building 100, for example. The control unit 40 is not provided along with the distribution board 4 but is separated from the distribution board 4. The control unit 40 is installed on the ceiling.

  The lighting device 20 includes a first housing part (housing part) 81. The first accommodating part 81 accommodates the first lighting part 30 and the control part 40. Specifically, the first accommodating portion 81 accommodates the first lighting circuit 31, the first lighting power supply circuit 32, the receiving portion 41, the control circuit 42, and the third circuit board 50. The first accommodating portion 81 is installed in the vicinity of the first light source 11. The slave lighting fixture 3a has a second accommodating portion 82. The second housing part 82 houses the second lighting part 70. Specifically, the second housing part 82 houses the second lighting circuit 71, the second lighting power supply circuit 72, and the fourth circuit board 73. The second accommodating portion 82 is installed in the vicinity of the second light source 12. Each of the 1st accommodating part 81 and the 2nd accommodating part 82 is a power supply case, for example. Each of the 1st light source 11 and the 2nd light source 12 is installed in a ceiling, and irradiates light toward a room | chamber interior from a ceiling.

  As described above, as described with reference to FIGS. 6 and 7, the lighting fixture 3 is installed on the ceiling. Therefore, the control unit 40 is installed on the ceiling without being installed on the wall. As a result, when installing the control unit 40, it is not necessary to perform a complicated operation such as an operation of making a hole in the wall and fixing the control unit 40 to the wall. Moreover, when installing the control part 40 in a wall, in order to pull out the connection part (end part) of the electrical wiring in the back side of a wall to the front side of a wall, it is necessary to provide a through hole in a wall. That is, a through hole for the control unit 40 must be provided separately from the through hole for wiring of the lighting fixture 3. In the present embodiment, the control unit 40 is installed at the same time as the lighting fixture 3 is installed. Therefore, there is no need to provide a through hole only for the control unit 40. As a result, the complexity of the installation work of the control unit 40 can be reduced.

  Further, the first lighting circuit 31, the first lighting power supply circuit 32, the receiving unit 41, the control circuit 42, and the third circuit board 50 are accommodated in a single first accommodating unit 81. Therefore, the apparatus can be made compact.

  Next, with reference to FIG. 6 and FIG. 7, an apparatus configuration for receiving the information transmitted by the transmission unit 22 wirelessly by the reception unit 41 of the control unit 40 will be described. In the seventh embodiment, the information wirelessly transmitted by the transmission unit 22 indicates first information and second information. Hereinafter, information wirelessly transmitted by the transmission unit 22 is referred to as wireless information.

  As shown in FIG.6 and FIG.7, the 1st accommodating part 81 is formed with a metal material from a viewpoint of ensuring heat dissipation, for example. The first accommodating part 81 accommodates the receiving part 41. The first housing part 81 has a hole that communicates the inside and the outside of the first housing part 81. A part of the receiving part 41 is exposed to the outside of the first housing part 81 through a hole.

  Therefore, the receiving unit 41 can receive wireless information at a portion exposed from the first accommodating unit 81.
