Abstract:

An LED luminaires power supply that isolates dangerous line power from the LED luminaires. The power supply's footprint may enable retrofitting in existing lighting fixtures (e. g. , replace ballast in florescent tube troffer). The power supply may individually power a plurality of LED luminaires based on power requirements of the individual LED luminaires. The power supply may receive and interpret TRIAC dimmer signals and/or other lighting protocol commands and provide dimming and/or other lighting scenarios to the LED luminaires. The power supply may include identification readers to read identification and/or power requirements for the LED luminaires being powered thereby (stored in luminaires or in adapters connected to luminaires). The LED luminaires driven by the power supply may include individual lighting fixtures (e. g. , LED tubes, LED bulbs), a plurality of LED light arrays in a single light fixture (e. g.
