It's no secret that LED bulbs are far more efficient than traditional incandescent lights. One drawback, though, is a different look than the bulbs that people are accustomed to. Philips has just launched a new clear LED bulb that features the traditional light bulb shape and look, but with the efficiency benefits of modern offerings. Read More

In regular microchips, work is performed via the movement of electrons within the chip. Thanks to the recent creation of the thinnest-ever LEDs, however, such chips may one day be able to use light instead of electrons, saving power and reducing heat. Of course, those LEDs could also just be used as a really flat form of lighting, in any number of applications. Read More

Although known for long life and low energy consumption, the LED uses a DC power supply, or driver, to overcome its sensitivity to current fluctuations, and it’s the high-frequency, high-speed switching transistors in this driver that’s made the LED so costly for use in large-scale commercial applications dominated by fluorescent and incandescent lighting. But that’s about to change. Fraunhofer researchers are developing a new, more economical means of making the high-performance gallium nitride transistors needed for the LED’s high-efficiency driver.
