Title:
CONTROLLING THE LIGHT OUTPUT OF ONE OR MORE LEDS IN RESPONSE TO THE OUTPUT OF A DIMMER
Document Type and Number:
WIPO Patent Application WO/2012/162510
Kind Code:
A3
Abstract:
An apparatus for controlling the brightness of one or more light emitting diodes includes a sensing circuit to sense a dimming level of a dimmer. A microprocessor receives from the sensing circuit a signal indicative of the dimming level, and a drive circuit drives the one or more light emitting diodes. The microprocessor is arranged to generate a PWM waveform or current level corresponding to the dimming level and to provide the PWM waveform or current level to the drive circuit.
