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 ...

This is a circuit in which LED glows slowly in the beginning, then grows brighter and once again slowly it becomes dim. The basis of the whole circuit is an operational amplifier IC named LM358. This ...

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 ...

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, ...
