All that is required is to open and close the provided opening / closing member.

Conventionally, since the luminaire has been operated with a keyboard, a joystick, etc., the driving direction of the driven part of the luminaire has nothing to do with the operating direction on the remote control device, and therefore the luminaire. It was necessary to become familiar with the remote control operation in order to operate quickly.

Therefore, it is not necessary to be proficient in operating the lighting equipment, and anyone can easily operate the lighting equipment.

Therefore, it is possible to greatly reduce the time for lighting preparation, that is, preparation, on the stage or in the studio.

In the above-described embodiment, the address input section is provided on the reference member of the remote control device, but it may be provided on another part, for example, on the back surface of the remote control body, or may be configured differently. This may be omitted if it is not necessary to specify the luminaire.

Further, in the above-mentioned embodiment, the remote control device is configured as a fixture-type remote control similar to the structure of the lighting fixture in order to facilitate understanding of the invention, but the present invention is limited to such a configuration. Rather, a movable part corresponding to the degree of freedom of movement of the driven part of the lighting fixture is provided, and a sensor capable of detecting the amount of change in these movable parts is provided, and the driving part of the lighting fixture is controlled according to these amounts of change. Can be configured as. Therefore, the remote controller of the embodiment may have a simpler configuration.

Further, in the above-mentioned embodiment, the description has been made on the premise that one remote controller is used, but it goes without saying that a plurality of remote controllers may be used to perform a plurality of controls. With such a configuration, the charging time can be further shortened.
