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 ...

When the lights in your home start to flutter, your first instinct is usually to blame the bulb. Sometimes that is all you are dealing with, but persistent or widespread flicker often points to deeper ...

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 ...
