ABSTRACT:
A control circuit for a lighting system allows analog control over a first range of illumination intensities in which the intensity of the illumination source varies in proportion to the voltage level of the control signal. The circuit provides for improved dimming and color mixing capability by allowing pulse width or frequency modulation control in addition to analog control over a second range of illumination intensities.
