PURPOSE:To have appropriate illuminance at all times and save the energy by furnishing a switch for making lightup/extinction about each lighting load system previously allocated, and by allocating the switch previously with a certain luminance. CONSTITUTION:A wall switch 5 is allocated with a lighting load or loads 4 previously. This allocation is made using a card 8, and further the wall switch 5 is allocated with illuminance at the time of lightup of a lighting fixture 4. These data are stored in a memory of a main operation board 1. When the wall switch 5 is turned on, a lightup signal is delivered to the main control board 1 via a transmission line 3. The main operation board 1 specifies the wall switch 5 turned on upon receiving the signal and reads the data of the lighting load system allocated to the wall switch 5 and its illuminance from the data stored in the memory. The main operation board 1 prepares transmission signal so as to lightup the lighting load system with specific illuminance and delivers to the transmission line 3. A terminal unit 2 lights up the load 4 specified through reception of this transmission signal at a certain luminance. |
