A few years ago, the highest power LEDs you could buy capped out around three watts. Now, LED manufacturers are taking things to ridiculous power ratings with 30, 40, and even 90 watt LEDs. Getting ...

MSI motherboards use light-emitting diodes to report the status of the computer. Most computers have an LED for the power and an LED for the hard drive. If the PC is turned on, the power LED glows ...

Driver circuits are available in a variety of topologies. These include series (switch-mode) drivers, and parallel (non-inductor) drivers. How LEDs are driven depends on the level of efficiency ...

Long used in instruments and computers as visual indicators for signal integrity and operations status, LEDs are ideal choices due to their high reliability, low power use, and ...

Recent breakthroughs in LED technology have enabled LEDs with a broad spectrum of light output to be produced and not just the traditional red and green derivatives. Hence the sheer numbers of LEDs ...

But there’s a problem with this idea. First, the resistor will possibly dissipate a large amount of power. For instance, a resistor used to drop 12 V (a common voltage used for halogen task lighting) ...

LifeSafety Power’s ProWire now includes magnetic, LED light strips for the E6, E8 and E12 products, a free, value-add component that brings instant illumination to enclosures to assist with installing ...

Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...

Researchers at Ben-Gurion University of the Negev have demonstrated a novel way to spy on electronic conversations. A new paper released today outlines a novel passive form of the TEMPEST attack ...
