LIGHT EMITTING DIODE (LED) DIMMER CIRCUIT AND DIMMING METHOD FOR LEDS

摘要

A dimmer circuit(100) and a dimming method for an event based integrated driver system for a light emitting diode lighting application is disclosed. Dimmer circuit(100) includes a front end module for receiving an external dimming input in an analog domain, a digital domain or software domain and for operating a dimming output; an event generator for generating a plurality of events in a prioritized manner to trigger a respective response through front end module; and a firmware module configured for storing instructions for processing the plurality of events in the prioritized manner and for processing each response to implement a functionality in dimming output, where front end module, event generator and firmware module communicate with each other to generate dimming output of the one or more LEDs, and the dimming output has at least one of a linear profile, a non linear profile, a custom profile or combinations thereof.
