PURPOSE:To perform the remote control operation from the area of a wide range including corners of a room by arranging multiple infrared remote control receivers at fitting angles and positions with different sensing areas respectively. CONSTITUTION:When infrared rays containing the command to light a fluorescent lamp is sent from a remote controller 2 directly to a receiver 11 or to a receiver 12 after being reflected by a ceiling 3 or to both receivers 11 and 12, a CPU 14 reads it and outputs the lighting command signal to an AC switch circuit 17. A lighting fixture is operated by remote control when any of multiple receivers receives infrared rays, the operation area is expanded, and the remote control operation can be performed from nearly the whole area of the room having the lighting fixture. |
