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, ...

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 ...

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 ...

They’re consistently popular with the readers, which is admittedly part of my (and EDN’s) motivation to continue doing them. But I personally also find them fascinating; inevitably I come across at ...

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 ...

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 ...

The $150 Lutron Smart Bridge turns Lutron's un-smart dimmer products into Wi-Fi-enabled home automation pros. While the Smart Bridge and corresponding app work incredibly well, $150 feels excessive ...
