Semiconductor light emitting device including circular ring-shaped metal ring body and regulation holes define bottom of lens, and method for manufacturing same

Abstract

A semiconductor light emitting device includes a plane substrate having a flat substrate surface, a semiconductor light emitting element mounted on the substrate surface, and a lens formed of a resin which embeds the semiconductor light emitting element and condenses light emitted from the semiconductor light emitting element. A circular ring-shaped metal ring body surrounding the semiconductor light emitting element, and a plurality of regulation holes arranged inside the metal ring body at positions rotationally symmetric with respect to the center of the metal ring body are provided on the substrate surface. A bottom of the lens is defined by the metal ring body and the regulation holes. A body part of the lens has a plurality of valley portions extending toward the top of the lens from the positions of the regulation holes. The top of the lens has a surface as a spheroid surface with an axis vertical to the substrate surface and passing through the center of the metal ring body as a major axis.
