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 ...

The lighting industry has relied on the incandescentbulb for more than a century, and,over the last 50 years, the phase dimmer hasbecome the main dimming control. Standardforward-phase, or TRIAC ...

In general terms, dimmers are devices that vary light level (intensity) of lamps by controlling the amount of power that is delivered to the lamp. Dimming can be controlled by either manual or ...

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 ...

Users can easily reduce energy usage with dimmers. Dimming technology has evolved considerably over the last decade, especially in the arc discharge lamp category. What began as a device for simply ...

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 ...

Promising to extend LED life via a patent-pending control architecture, the LM3445 TRIode for alternating current (TRIAC) dimmable LED driver enables off-line, uniform flicker-free dimming of ...
