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 ...

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 ...

The compact fluorescent lamp (CFL) has not been the success it ought to have been. It is so unlike conventional incandescent lamps that consumers have trouble accepting it, despite the significant ...

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 ...
