LIGHTING CONTROL SYSTEM FOR DIFFERENT LOAD TYPES

摘要

An improved signal generator that is capable of providing a multitude of control schemes to connected ballasts or transformers to adjust the luminous output of an attached lamp or light source. The control scheme is preferably at least one of the type 0 to 10V sink, 0 to 10V source, pulse width modulated (PWM), and digital serial interface (DSI). A lighting control system for selectively controlling the respective light levels of a plurality of lighting loads of different load types, comprising a lighting control unit for generating zone-intensity information representing a desired light level for lighting loads including light sources on a communications link, each lighting load being one of a plurality of voltage controlled load types, duty cycle controlled load types, and digital signal controlled load types; a controller operatively connected to the lighting control unit via the communications link and responsive to the zone-intensity information on the communications link for adjusting the light level of the lighting loads; and a plurality of modules connected between the controller and the lighting loads, each module capable of controlling at least one of the lighting loads.
