METHOD AND SYSTEM FOR CONTROLING A LUMINAIRE

WIPO Patent Application WO2007003037

B1

Methods and corresponding systems for controlling a light fixture include a memory for storing data and software. A multi-tap capacitor has a plurality of tap capacitors integrated into a capacitor housing. A plurality of switches are each coupled to one of the plurality of tap capacitors for selectively coupling the tap capacitors together to produce a variable multi-tap capacitance. A processor is coupled to the memory and the switches to facilitate: detecting a trigger for changing a lumen level output by the light fixture; determining a new lumen level in response to the trigger; determining a capacitance value that corresponds to the new lumen level; and configuring the plurality of switches to produce the multi-tap capacitance that corresponds to the new lumen level. The processor can record data in the memory that represents times of lumen changes and switch settings, which data correlates to power consumption.
