Title:

LOW-COST LOW-POWER LIGHTING SYSTEM AND LAMP ASSEMBLY

Document Type and Number:

WIPO Patent Application WO/2015/116489

Kind Code:

A3

Abstract:

In accordance with embodiments of the present disclosure, a method and apparatus may include receiving an input waveform from a dimmer, wherein the input waveform is periodic at a first frequency. The method and apparatus may also include generating an output waveform independent of a load coupled to the output waveform, wherein the output waveform is periodic at a second frequency substantially greater than the first frequency, wherein at least one of the second frequency and an amplitude of the output waveform is based on a phase-cut angle of the input waveform indicative of a control setting of the dimmer.
