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 ...

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, ...

TRIAC-dimmers were originally designed to dim incandescent filament lamps. The elimination of these lamp types increases the need for alternative dimming methods. The use of TRIAC-dimmers in ...

Solid-state lighting (SSL) differs from conventional lighting in that it uses light-emitting diodes (LEDs) instead of filaments, plasma, or gases. Although still relatively early in its development, ...

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 ...

True to the history of other types of semiconductor products, LEDs offer better performance at a lower cost with every passing year. So much so, in fact, that the other elements of a conventional LED ...
