Abstract
A universal lighting source controller including integral power metering for use with substantially all light source types including fluorescent, incandescent, magnetic low voltage, electronic low voltage, light emitting diode (“LED”), high density discharge (“HID”), neon, and cold cathode. The lighting source controller includes a line voltage dimming circuit that can control the intensity of light sources in a lighting circuit and measures the actual amount of power consumed by the light sources. The line voltage dimming circuit includes a triac circuit for controlling this intensity and current and voltage detection circuits for measuring the power consumption. The lighting source controller can also include low voltage dimming circuits to provide a control signal to light sources having electronic or magnetic dimming ballasts to set the intensity of these light sources.
