PROGRAMMABLE LIGHTING CONTROL SYSTEM WITH NORMALIZED DIMMING FOR DIFFERENT LIGHT SOURCES |
摘要 |
A lighting control system is adapted to dim a plurality of groups of light sources in a room to any one of a number of different preset levels to achieve a like number of different lighting scenes. Each group of light sources defines a lighting zone of the same type of light source, for example, incandescent lamps, fluorescent lamps, neon lights, etc. The system includes a plurality of dimmers for adjusting the respective light levels of the different lighting zones, and a display panel for displaying the instantaneous light level of each zone. According to the invention, a suitably programmed microprocessor or the like operates to normalize the system's dimming performance for a plurality of different types of light sources so that a given change in dimmer setting produces the same change in perceived light level from each of the different types of light sources. Preferably, a system user inputs the type of light source used in each zone by a software scheme that operates the light level indicators of the display panel in an alternative mode to indicate the various types of light sources. |
