LED Chips, on the Cheap LED bulbs have long been lauded as an energy-efficient alternative to incandescent bulbs. But LED, or light-emitting diode, bulbs are expensive to produce, which has kept ...

Need a low-power light that’s five times brighter than a typical LED? SANSI’s got you covered. Due to the physical placement of LEDs within the bulb and the design of their electronics and heat sink, ...

They’re consistently popular with the readers, which is admittedly part of my (and EDN’s) motivation to continue doing them. But I personally also find them fascinating; inevitably I come across at ...

LED bulbs are a far more cost-efficient, environmentally-friendly option than traditional incandescent bulbs. With a life expectancy of 20 years or more (25x longer than incandescent), the energy ...

The incandescent light bulb will soon no longer be the go-to choice for lighting. It has been a long time coming, but the cost structures normally associated with LED equivalents have dropped ...

To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.

Tokyo — Nichia Corp. has developed a white-LED chip with 100-lumen/watt efficiency, with volume production expected this year. The move comes amid an intensifying race to boost the efficiency of white ...

Early adopters of LED lighting will remember 50,000 hour or even 100,000 hour lifetime ratings printed on the box. But during a recent trip to the hardware store the longest advertised lifetime I ...

Apparently, it's time to ban Edison's venerable, now vilified, light bulb. European leaders, green pundits and the widely reported light bulb provisions of the U.S. Energy Independence and Security ...
