One of the biggest challenges for new, energy-efficient CFL and LED-based lights that will replace incandescents is working with existing triac-based dimmer switches. Triac dimmers vary widely in both ...

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 ubiquitous triac dimmer can still work with LED lamps, thanks to new ICs. Energy-efficient lighting is in the headlines as we approach the date at which federally mandated efficiency levels for ...

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 ...

IR's Peter Green describes the circuitry that allows CFLs and LEDs to be dimmed by legacy triac wall dimmers. The compact fluorescent lamp (CFL) has not been the success it ought to have been. It is ...
