abstract

A wings type imbedded electrode was introduced into the lateral light emitting diodes (WTIE-LEDs) to improve the light shading effect from the metal electrode of LED. The wing type imbedded contact structure was expected to eliminate the light shading of electrode and bonding wire, and further increased the light extraction and light output power. At 100 mA injection current, the WTIE-LED structure enhanced the output power of 41.6% as compared with that of conventional sapphire-based LEDs (CSB-LEDs) Moreover, the output power of the packaged WTIR-LED and CSB-LED is 70 and 88.94 mW, respectively, at the same injection condition. A 27% enhancement of light output power was achieved. Therefore, using the imbedded contact to reduce light shading would be a promising prospective for vertical LEDs to achieve high output power. © (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
