The graph also nicely displays why incandescents have been booted off the market for a failure to achieve sufficient efficiency, as they have flatlined at around 15 lumens per Watt. John Timmer ...

This is a design idea of high efficiency constant current buck converter for LED lighting using LinkSwitch-TN. It operates in an input voltage ranging from 108 VAC to132 VAC and delivers an output of ...

Researchers at the US Rensselaer Polytechnic have proven a link between LED efficiency drop at high current and carrier mobility. Better lighting LEDs could result. “Efficiency droop, first reported ...

Whenever the LED is off, R2’s current increases to well over 100 µA, constantly wasting power. If R2 is returned to the collector of Q2 instead of ground, the dropout voltage jumps to 1.5 V or ...

Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light. The devices are ...

When Facebook unveiled its new Graph Search function earlier today, it also unveiled the two people who spearheaded the new "third pillar" of Facebook: Lars Rasmussen and Tom Stocky, two heavy ...

A modified boost converter topology is proposed to achieve better than 89% efficiency as an LED driver for applications in which low supply voltage and low average current are desired such as in a ...
