Low-Cost, Low-Power Lighting Systems and Lamp Assemblies

Abstract

According to embodiments of the present disclosure, methods and apparatus may include receiving an input waveform from a dimmer, wherein the input waveform is periodic at a first frequency. The methods 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 the second frequency of the output waveform and At least one of the amplitudes is based on a tangent angle of the input waveform indicative of a control setting for the dimmer.

Description

technical field [0001] The present disclosure relates generally to the field of electronics, and in particular, to low power lighting systems and methods related thereto, as compared to methods for ensuring compatibility between one or more low power lamps and the electrical infrastructure to which they are coupled. conventional method, which can provide a lower cost solution. Background technique [0002] Many electronic systems include circuitry such as switching power converters or transformers that interface with dimmers. The interface circuit delivers power to the load according to the dimming level set by the dimmer. For example, in a lighting system, a dimmer provides an input signal to the lighting system. The input signal represents a dimming level that causes the lighting system to adjust the power delivered to the lamps and thereby increase or decrease the brightness of the lamps according to the dimming level. There are many different types of dimmers. Genera...
