The light source unit 20 uses, for example, a light emitting diode (LED) as a light source. However, the light source unit 20 may use a solid light emitting element (organic electroluminescent element) other than an LED, a fluorescent lamp, or the like as a light source.

  The power supply unit 21 is configured to convert an AC voltage / AC current supplied from the AC power supply 5 through the power supply line 6 into a DC voltage / DC current and to supply power to the light source unit 20. That is, the light source unit 20 is configured to be lit with a DC voltage / DC current supplied from the power source unit 21. However, the power supply unit 21 is configured to make the output (DC voltage / DC current) variable.

  The control unit 4 includes a wireless communication unit 40, a load control unit 41, a power supply unit 42, and the like. The radio communication unit 40 receives a radio signal transmitted from the radio communication unit 32 of the operation unit 3, digitally demodulates a transmission frame from the received signal (reception signal), and passes the digital signal to the load control unit 41.

  The load control unit 41 is preferably composed of a microcontroller. The load control unit 41 acquires operation data from a transmission frame received from the wireless communication unit 40, and generates a control signal corresponding to the operation data. The control signal is, for example, a pulse width modulation (PWM) signal, and is configured to represent the dimming level by an on-duty ratio. The control unit 22 of the illumination device 2 controls the power supply unit 21 so as to increase or decrease the DC voltage / DC current supplied to the light source unit 20 in accordance with the dimming level indicated by the control signal (PWM signal). That is, the lighting device 2 is dimmed and controlled by the lighting control device 1. However, the dimming level is expressed as a ratio where the light output at the rated lighting is 100%, and 0% when the light is turned off.

  That is, the lighting control device 1 of the present embodiment can collectively change the dimming levels of the plurality of lighting devices 2. For example, each time the operation member 31 of the operation unit 3 is pulled, the light is turned off (light control level: 0%) → rated light (light control level: 100%) → light control light (light control level: 50%) → It is only necessary that the light can be changed cyclically in the order of light control lighting (light control level: 25%) → light-off. That is, every time operation data is received from the wireless communication unit 40, the load control unit 41 of the control unit 4 switches the dimming level from 0% → 100% → 50% → 25% → 0% and transmits a control signal. .

In this case, the load control unit 41 of the control unit 4 may store a plurality of scenes individually corresponding to a plurality of types of operation data in a memory (a memory built in a microcontroller; the same applies hereinafter). preferable. The “scene” stored in the memory indicates a combination of operating states of the individual lighting devices 2.

  For example, a combination in which all the plurality of lighting devices 2 are in the rated lighting state may be referred to as scene 1, and a combination in which all the lighting devices 2 are in the off state may be referred to as scene 0. In addition, some (for example, five of the ten) lighting devices 2 are in a lighting state with a dimming level of 50%, and the remaining (for example, the remaining five of the ten) lighting devices 2 are in the lighting state. A combination that is in a lighting state with a dimming level of 25% may be set as the scene 2.

  For example, the operation signal unit 30 of the operation unit 3 starts a time limit for a predetermined time (for example, 3 seconds) by a timer from the time when the operation member 31 is pulled, and the number of operations within the predetermined time (time limit for the predetermined time). Including 1 time just before the start). Then, the operation signal unit 30 determines a scene corresponding to the number of operations within a predetermined time, such as scene 0 if once, scene 1 if twice, scene 2 if 3 times, and the number of the determined scene It is preferable to pass (0, 1, 2,...) To the wireless communication unit 32 as operation data. The wireless communication unit 32 transmits a transmission frame including the operation data received from the operation signal unit 30 to the control unit 4 using a wireless signal.

  When receiving the operation data received from the operation unit 3 by the wireless communication unit 40, the load control unit 41 of the control unit 4 reads a scene corresponding to the operation data (scene number) from the memory. For example, when the scene 2 is read from the memory, the load control unit 41 transmits a control signal instructing the lighting devices 2 having the identification codes 1 to 5 to be lit at a dimming level of 50%. Further, the load control unit 41 transmits a control signal instructing the lighting devices having the identification codes of Nos. 6 to 10 to be lit at a dimming level of 25%.

  The control part 22 of each illuminating device 2 receives only the control signal which corresponds to an own identification code. The control unit 22 controls the power source unit 21 so that the light source unit 20 is turned on at a dimming level (50% or 25%) indicated by the received control signal. As a result, the scene selected by operating the operation unit 3 is reproduced by the illumination control device 1. However, each scene is not limited to the content described above.
