A high-output blue-light-emitting diode (LED) developed by Cree Research (Durham, NC) is 20 times brighter than Cree`s existing blue LED and has a typical radiant output of 500 µW, measured at 20 mA, with a peak wavelength of 430 nm and bandwidth of about 65 nm. The structure includes gallium nitride grown on silicon carbide. According to the company, the brightness of this device will make possible high-performance full-color LED displays; the blue LED has been combined with available high-brightness red and green LEDs to create clusters capable of producing all colors of the spectrum, including white. The company intends to use these clusters as building blocks for several LED-based display products.
