ABSTRACT:
A LED dimming circuit is provided. The LED dimming circuit has an LED driver, an LED dimmer, and at least one LED light source. A resistor is connected between a dimming control output of the LED dimmer and dimming control input of the LED dimmer. The LED dimming circuit may optionally include a fluorescent slide dimmer. The fluorescent slide dimmer may have a first connection to the dimming control input of the LED dimmer and a second connection to a circuit common of the LED dimmer. A method of providing an LED dimming circuit for dimming at least one LED light source using a fluorescent dimmer is also provided.
