Cotco’s TBL blue LEDs maximize extraction efficiency

Feb. 17, 2005
Date Announced: 17 Feb 2005 The Cotco TBL Blue Series LEDs utilize the most recent advances in InGaN/SiC technology. The die process combines highly efficient InGaN materials with a Silicon Carbide (SiC) substrate in a geometrically enhanced Epi-down chip structure design to maximize light extraction efficiency. The material also incorporates a current distribution layer that requires only a single wire bond for increased LED reliability. The vertically structured LED chips are approximately 115 microns in height and require a low forward voltage. This die improvement to Cotco’s High Brightness LED family greatly enhances the performance of a broad range of applications such as decorative lighting, full color video screens, mobile appliance lighting, and automotive illumination.With luminous intensities of up to 12,000mcd, the TBL Blue LEDs from Cotco provide a luminous intensity that is significantly brighter than products currently available on the market today. TBL Blue LEDs are available in 5mm round and elliptical package styles with a variety of viewing angles to choose from. The TBL Blue series of LEDs represents Cotco’s next generation of solid-state LED products that succeed in delivering superior price and performance for high intensity LEDs.
