PURPOSE:To optimumize luminance to be matched with the lightness of a room, in which a loading state display device is set, by switching the emissive luminance of a display means to display the state of load. CONSTITUTION:When the light of a living room, etc., is turned on, a monitoring means 13 transmits a monitored result to a control means 14. According to the set contents of a luminance setting switch 17 in a luminance setting means 12, the means 14 changes the luminance of a pilot lamp 16 through a display means 11. Thus, the luminance can be made optimum to be matched with the lightness of the room. |
