In general terms, dimmers are devices that vary light level (intensity) of lamps by controlling the amount of power that is delivered to the lamp. Dimming can be controlled by either manual or ...

The LM3445 from National Semiconductor enables a full 100:1 range of offline, uniform, flicker-free dimming for high-brightness LEDs with a conventional TRIAC forward or reverse phase-control wall ...

To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...

LED driver designs can deliver flicker-free and fast startup dimming performance while still providing high power factor and efficiency, writes Rich Miron Dimming performance of LED lamps in legacy ...

Using LEDs for lighting is an ever-more-popular application because of its high efficacy and long life. Dimmable lighting applications in residential and commercial installations will account for over ...

Trailing-edge dimmers offer smoother, quieter control for modern lighting systems—but their inner workings often remain overlooked. This post sheds light on the circuitry behind the silence. Sometimes ...
