Configurable LED driver/dimmer for solid state lighting applications

摘要

A configurable light emitting diode (LED) driver for powering a set of light fixture loads including a power circuit and a primary controller for controlling the power circuit. The driver further includes a set of output current drivers, each of the set of output current drivers connected to one of the set of light fixture loads for controlling the associated light fixture load and a secondary controller for controlling the set of output current drivers. The driver also includes an apparatus for mapping the set of output current drivers to various dimming zones and for mapping output channels into groups.
