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 ...

Fairchild Semiconductor introduced the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC) for use with triac and analog dimming compatibility. Fairchild ...

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 ...

We see a lot of traffic on the tips line with projects that cover old ground but do so in an instructive way, giving us insight into the basics of electronics. Sure, commercial versions of this ...

When operating a standard light switch, your choices are limited to turning the lights on or off. However, a light dimmer provides more versatility. Depending on the type of dimmer you choose, you can ...
