Method for manufacturing light emitting apparatus, light emitting apparatus, and mounting base thereof

Abstract

The present invention provides a method for manufacturing a light emitting apparatus which can be separated by splitting, even though a mounting plate made of metal is employed. A metal plate is prepared, on which at least one joint slit made up of a joint and an opening is formed in a predetermined direction for integrating multiple mounting plates of the light emitting apparatuses. Multiple light emitting elements set in array are mounted on the metal plate. An aperture is provided at a position corresponding to a position for mounting the light emitting element on the metal plate, and a plate-like reflector made of resin, on which a first reflector splitting groove is formed at a position coinciding with the joint slit of the metal plate, is mounted and fixed on the metal plate in such a manner as superimposed thereon. The metal plate and the plate-like reflector being superimposed and fixed one on another are broken along the joint slit of the metal plate and the first reflector splitting groove of the plate-like reflector. The metal plate and the resinous reflector are superimposed one on another and broken together, whereby the metal plate can be split successfully.
