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 ...

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 ...

LEDs are rapidly becoming the preferred choice for lighting in many situations due to their efficiency, versatility, flexibility, long life, and cost-competitiveness. But unlike the traditional ...

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 ...

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 ...

Energy-efficient lighting is in the headlines as we approach the date at which federally mandated efficiency levels for lights will make ordinary incandescent lighting obsolete. Incandescent lights ...
