Abstract
According to one embodiment of the invention, a method comprises receiving a time-varying power waveform. The power waveform may be periodic and/or phase-controlled. Compressed within a power range associated with the time-varying power waveform, a pulse width modulated (PWM) signal is produced, which is supplied to a light source in order to produce a lighting effect emulating lighting from a candle flame.
