发明名称 LED reflector for improved light extraction
摘要 Light emitting diodes are provided with electrode and pad structures which redirect light which otherwise would be blocked by the pad. The LED may be formed as a die with first and second contact surfaces. A pad is in contact with the first contact surface. A reflector is disposed beneath the first pad, and the reflector includes walls that are oblique with respect to the first contact surface.
