ABSTRACT:
A semiconductor light emitting apparatus can be configured to reduce color variations and intensity variations with a simple configuration. The semiconductor light emitting apparatus can include a substrate having conductive members including chip mounting areas and electrode areas, a plurality of semiconductor light emitting device chips mounted in the chip mounting areas on the substrate, a reflector formed on this substrate so as to surround the semiconductor light emitting device chips, and a fluorescent material and a light diffusing material arranged distributedly inside this reflector. The semiconductor light emitting apparatus can be configured so that the semiconductor light emitting device chips emit light only from their top surfaces, and a first light transmitting resin containing the fluorescent material is applied only to the top surfaces of the semiconductor light emitting device chips.
