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 ...

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, ...

A recent discussion with Scott Brown of iWatt revealed some interesting facts about the design of IC drivers for consumer LED lighting. Although LED lifetime can reach about 20 years and the power ...

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 ...
