Dimmer switch

A wall mountable control panel for controlling power levels delivered to electrical loads, such as lighting loads defining zones, has a zone select switch for scrolling through multiple zones, so as to permit a single control unit (having a power level adjustment switch and a power level display for one zone) in the control panel to be used to separately adjust the power level for, and separately display the power level of, more than one zone. The control panel is capable of controlling M times N zones, where N is the number of control units in the control panel, and where M represents the number of selections that can be made by the zone select switch.

Wall-mountable lighting control panel

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.
