Abstract

A semiconductor light emitting package is discussed, which includes a base having a top surface with a flat portion; a semiconductor light emitting device on the base; an electrical circuit layer electrically connected to the semiconductor light emitting device; a screen member having an opening and disposed on the base around the semiconductor light emitting device, the screen member shaped into a substantially circle; and an optical member formed of a light transmissive material such that light emitted from the semiconductor light emitting device passes therethrough, wherein a bottom surface of the screen member is positioned higher than the semiconductor light emitting device, an edge portion of the optical member is in contact with the screen member, a top surface of the optical member is substantially parallel to the flat portion of the base.

Claims (29)

1. A semiconductor light emitting package, comprising:
