The control unit 220 is connected to the interface unit 210 and executes dimming processing based on information received by the interface unit 210 from the hub 30. In addition, the control unit 220 performs dimming processing based on information received from the operation panel 90 via an external input terminal 250 (described later). Details of the control unit 220 will be described later.

  The storage unit 230 stores information received from the interface unit 210 and information received from the operation panel 90 via the external input terminal 250. For example, the storage unit 230 stores information on the intensity of illumination light generated by the illumination unit 100, information on a lighting state, a light-off state, and timing of lighting / light-off. Note that the storage unit 230 may not be provided, and the content of control in the control unit 220 may be sequentially transmitted to the hub 30 via the interface unit 210, and the hub 30 may be transmitted to the server 10 and stored in the server 10. The lighting device 200 may perform control based on information input from the interface unit 210 and the operation panel 90 without managing information.

  The insulated power supply 240 is supplied with power from the power supply 80 and supplies power in a state where it is insulated with respect to predetermined components in the lighting device 200. There is no particular limitation on which part in the lighting device 200 is insulated. At least a part or all of the interface unit 210 and the control unit 220 may be insulated from the lighting unit 100.

  An example of realizing the insulated power supply 240 will be described with reference to FIGS. 3A and 3B. FIG. 3A is a diagram illustrating an example of a configuration for realizing the isolated power source 240 according to the first embodiment. FIG. 3B is a diagram illustrating another example of a configuration for realizing the isolated power source 240 according to the first embodiment.

  FIG. 3A shows an example in which an insulated power source 240 is realized using a transformer. As shown in FIG. 3A, it is conceivable that a transformer is arranged on the input side of the interface unit 210 to insulate the power supply from the power source 80 and supply power to the lighting device 200. In this case, since the insulation is realized in the front stage of the interface unit 210, the potential on the network 60 side and the potential on the illumination unit 100 side are insulated.

  FIG. 3B shows an example in which an isolated power source 240 is realized using a photocoupler. As shown in FIG. 3B, a photocoupler is inserted after the control unit 220, and a signal is transmitted to the control unit 101 via the photocoupler. In this case, insulation is realized in the subsequent stage of the control unit 220, so that the potential on the network 60 side and the potential on the illumination unit 100 side are insulated.

  The signal generation unit 221 receives input of information from the interface unit 210 and generates a control signal (dimming signal) for controlling the illumination unit 100 based on the received information. In addition, the signal generation unit 221 sends the generated control signal to the control unit 101 of the illumination unit 100.

  The control signal generated by the signal generation unit 221 is, for example, a dimming signal that indicates the illuminance of the illumination light of the illumination unit 100, a signal that instructs the illumination unit 100 to be turned on or off, or a voltage input to the illumination unit 100. The signal to be adjusted. Depending on the mode of dimming, the control signal may be a pulse width modulation (PWM) signal, a digital serial signal, or the like. Further, the control signal may be a signal for controlling the phase of the electric power input to the lighting unit 102, or may be a signal for controlling a DC voltage input to the lighting unit 102.

  The information generation unit 222 generates information regarding the operation of the lighting fixture 40 </ b> A and transmits the information to the server 10 via the interface unit 210 and the hub 30. In addition, when it is set as the structure which does not manage information in 40 A of lighting fixtures, the information generation part 222 does not need to be provided.

  The input unit 223 receives an input from the operation panel 90 via the external input terminal 250 and transmits it to the signal generation unit 221.

  The signal generator 221 can generate a control signal based on both information received from the interface unit 210 and information received by the input unit 223. When the information (control instruction) from the interface unit 210 and the information (control instruction) received by the input unit 223 conflict, in order to determine which is prioritized, the interface unit is placed before the signal generation unit 221. An arbitration unit that receives information from 210 and the input unit 223 and performs priority determination may be provided. Further, the signal generation unit 221 may be configured to always give priority to any input.

  Further, the information generation unit 222 may be configured to receive an input from the arbitration unit in the same manner as the signal generation unit 221. Further, the information generation unit 222 may be configured to receive the input from the signal generation unit 221 and execute the process, and may be configured not to receive the input from the interface unit 210 or the input unit 223 directly. Conversely, the information generation unit 222 may receive the input from the arbitration unit first, and the signal generation unit 221 may receive the input from the information generation unit 222 and generate a signal.
