Abstract :
This paper discusses the difficulties in dimming Edison socket LED lamps directly from residential phase modulated dimmer switches. In order to explain these difficulties PSpice models for the dimmers are proposed that necessarily include diac characteristics to improve accuracy. A method to dim the LEDs from the residential dimmers is discussed.
