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.
