We are all familiar with the snap-on phenomenon of inexpensive TRIAC dimmers that are often used to control incandescent lamps –turn the pot until the light comes (snaps) on and then reduce the ...

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 ...

(with input from: Henry Nguyen, Senior Applications Engineer, Diodes Inc., Peter Chan, Application Manager, SP Technology and Fred Ebeling, Application Manager, Blue Ridge Lighting Solutions) It is ...

National Semiconductor’s constant-current controller enables off-line, uniform, flicker-free dimming of high-brightness light-emitting diodes (LEDs) with a conventional TRIode for Alternating Current ...

Power Integrations has introduced a one-chip non-isolated LED driver for loads up to 22W. Capable of working from inputs from 90 to 305Vac, it is triac (and trailing-edge) dimmable on nominal 110V ...

Why wouldn't that one work for CFL bulbs? Its just a switch. Sure, you can't use dimmer switches on them but a sensor switch should be okay. edit: the only issue I can think of is that CFLs do not ...
