High-brightness A1GaInN light-emitting diodes

Currently, commercial LEDs based on A1GaJnN emit light efficiently from the uliraviolet-bhie to the green portion of the visible wavelength spectrum. Data are presented on AIGaJnN LEDs grown by organometallic vapor phase epitaxy (OMVPE). Designs for high-power A1GaInN LEDs are presented along with their performance in terms of output power and efficiency. Finally, present and potential applications for high-power AlGaTnN LED5, induding traffic signals and contour lighting, are discussed.
