Abstract
A lighting fixture, and methods for powering and operating same. The fixture comprises a housing having multiple portions. One or more power and control circuit boards are disposed in a first portion of the housing, comprising one or more switching power supplies for receiving an A.C. line voltage and providing a D.C. output voltage, and a communication protocol converter for receiving first lighting instructions formatted according to a first communication protocol and converting at least some of the first lighting instructions to second lighting instructions formatted according to a second communication protocol. A plurality of modular circuit boards are disposed in the second portion of the housing and coupled to the power and control circuit board(s). Each modular circuit board comprises a plurality of LED-based lighting units coupled to the D.C. output voltage and responsive to the second lighting instructions formatted according to the second communication protocol.
