Patent abstract
This invention discloses a light emitting semiconductor device including a light-emitting structure and an external optical element. The optical element couples to the light-emitting structure circumferentially. In addition, the refractive index of the external optical element is greater than or about the same as that of a transparent substrate of the light-emitting structure, or in-between that of the transparent substrate and the encapsulant material.
