Abstract
This disclosure describes systems, methods, and apparatus for an LED driver circuit capable of responding to dimmer signals from three different types of dimmers: a phase cut dimmer, a dedicated dimmer (e.g., 0-10V dimmer), and a button dimmer. The processor can include inputs for each of these dimmer types, and can be configured to determine which of the three types of dimmers is controlling the LED driver circuit, and determine which dimming signals to respond to when more than one dimmer type is trying to control the LED.
