Abstract

See full text

A circuit for a dimmer system is disclosed, in which a phase-cut dimmer output signal is converted to a dimming control level signal. The phase-cut dimmer output signal is used to generated a pulse modulated signal indicative of the duty cycle of the phase cut dimmer output signal, and the pulse modulated signal is directly converted to a piece-wise linear dimming control level signal. By directly converting the pulse modulated signal to a piece-wise linear dimming control level signal, no further processing is necessary to produce a dimming signal which closely resembles the ideal logarithmic response of the human eye.
