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 ...

This light dimmer control has active timing capacitor reset or AC line zero-crossing synchronization. The 13 additional components are garden variety and cost less than $2. Performance at the low end ...

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 ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...
