Light emitting semiconductor device e.g. an LED component

摘要

A light emitting semiconductor device (21) has a light emitting element (6) which is completely sealed with an opaque sealing resin (8) except for a light emitting region at the opposite side from its mounting substrate (1) or circuit board. Preferred Features: The light emitting element (6) comprises a sapphire substrate (6b) supporting a light emitting layer of GaN based compound semiconductor. The sealing resin (8) is reinforced with a filler such as aluminum oxide, carbon or silicon oxide.
