This is a very simple LED dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. Typical segment displays LEDs consume around 25 mA for each segment and should be limited to this ...

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 ...

To make LED fixtures even more energy efficient, learn how to properly dim the LED lamps. The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting ...

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, ...

Dialog Semiconductor has improved its LED light dimming intellectual property. “The first LED driver from this new platform, the iW3688, delivers smooth, flicker and shimmer-free dimming supporting ...

LED driver designs can deliver flicker-free and fast startup dimming performance while still providing high power factor and efficiency, writes Rich Miron Dimming performance of LED lamps in legacy ...

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 ...

Fig. 1: The dimmer circuit schematic showing the filtering capacitors. Rob Atkinson, K5UJ, is an engineer out of Saint Charles, Ill., and one of the many readers who enjoy the DIY projects we feature ...

I installed compact-fluorescent and LED bulbs throughout my house. They work well everywhere but not with dimmer switches. The bulbs either dim insufficiently, flicker, or they don't light at all.

Leviton's excellent 2nd-gen motion-sensing Wi-Fi smart dimmer (model D2MSD) can be combined with a wireless, battery-powered ...
