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 ...

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 ...

The basic schematic of an electronic transformer (ET) includes a traditional full-bridge rectifier, a self-oscillating chopping circuit, and an output-power transformer. The self-oscillating circuit ...

Improving triac dimming capability for LED lighting up to 20W, Power Integrations has introduced LYTSwitch-3. Compatibility with leading-edge and trailing-edge dimmers is claimed, plus support for a ...

A light dimmer is quite unusual in a caravan or on a boat. Here we describe how you can make one. So if you would like to be able to adjust the mood when you’re entertaining friends and acquaintances, ...

Maxim Integrated Products (introduces the MAX16841, an offline LED driver that provides flicker-free dimming from maximum light intensity down to zero intensity with both leading-edge (triac) and ...

Dialog Semiconductor has improved its LED light dimming intellectual property. “The first LED driver from this new platform, the iW3688, delivers smooth, flicker and shimmer-free dimming supporting ...
