LIGHTING SYSTEM

摘要

PURPOSE: To produce a comfortable space by controlling the light output of a first lighting load according to the change of light output of a second lighting load so that the difference in light output between the first lighting load and the second lighting load is minimized. CONSTITUTION: This system is formed of at least an illuminance detecting part for detecting the illuminance of a flat surface lighted by a first lighting load La1 and a first control part 21 for outputting a dimming signal to the first lighting load La1 It is also formed of at least a first lighting part for lighting a relatively wide space and a second control part 22 for outputting a dimming signal to a second lighting load La2 . This system also has a second lighting part for lighting a relatively narrow space. It further has a transmission device for transmitting the lighting information of the second lighting load from the control part 22 to the control part 21, and the light output of the load La1 is controlled according to the change of light output of the second lighting load so that the difference in light output between the load La1 and the load La2 is minimized.
