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 ...

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 ...

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 ...

Triacs are at the heart of dimming controls for LED lighting. Triacs used in dimmers have normally been characterised and specified for incandescent lamp loads, which have high current ratings 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 ...

Dialog Semiconductor has improved its LED light dimming intellectual property. “The first LED driver from this new platform, the iW3688, delivers smooth, flicker and shimmer-free dimming supporting ...

To make LED fixtures even more energy efficient, learn how to properly dim the LED lamps. The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting ...
