Dithering and dimming techniques for light emitting diode (LED) lighting systems
Various embodiments are described herein that relate to systems and methods for selectively providing current to power LEDs. The techniques introduced here can enable smooth dimming of the LEDs from maximum brightness down to “actual extinction” or “pseudo-extinction.” More specifically, the LEDs can be dimmed to extinction without any significant gaps in the levels of brightness (i.e., a noticeable drop rather than a smooth transition between brightness levels).
