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 ...

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 ...

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 ...

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 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 ...

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 ...

GlacialPower of Taiwan has announced a 300W constant voltage led driver series that supports triac dimming. GlacialPower of Taiwan has announced a 300W constant voltage led driver series that supports ...
