Abstract:
A light emitting device includes a board, a semiconductor light emitting element formed on the board optionally via a submount, a cap sealing the semiconductor light emitting element and a reflector provided surrounding the cap. The cap has top and bottom surfaces that are parallel to the top surface of the semiconductor light emitting element, and the spacing between the top and bottom surfaces is 1-3 times the longest diagonal or the diameter of the semiconductor light emitting element. Also disclosed is a process for producing the device.
