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, ...

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 ...

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, ...

Lights are an integral part of any home. With lighting being some of the important components in any home, users might be tempted to spice things up a little bit. Smart home systems are only now ...

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 ...

For several years manufacturers have been introducing LED bulbs onto the market with the eventual goal of replacing incandescent and CFL lamps. The design of these lamps has evolved from very simple ...

Trailing-edge dimmers offer smoother, quieter control for modern lighting systems—but their inner workings often remain overlooked. This post sheds light on the circuitry behind the silence. Sometimes ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...
