Gallium nitride transistors promise brighter future for LEDs

By - March 16, 2014 1 Picture
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.

LED-equipped cork turns wine bottles into lamps

There's an old camping trick, for people who don't want to bother getting a lantern: just stick a flashlight up against the bottom of a plastic pop bottle, turn the flashlight on, then bask in the bottle's glow. Now you can do the same sort of thing with wine bottles, using suckUK's bottlelight. Read More
