Abstract:
1. A semiconductor light source apparatus, comprising: a substrate having a mounting surface; at least one phosphor layer disposed on the mounting surface of the substrate via an adhesive material, and the at least one phosphor layer composed of at least one of a glass phosphor and a phosphor ceramic which includes substantially no resin component; and a semiconductor light source having an optical axis and a light-emitting area, the semiconductor light source located adjacent to the at least one phosphor layer so that the optical axis of the semiconductor light source intersects with the mounting surface of the substrate at an angle between 0 degrees and 90 degrees while the light-emitting area of the semiconductor light source is located on the at least one phosphor layer to wavelength-convert light emitted from the semiconductor light source by the at least one phosphor layer, and wherein the light source is configured such that light emitted from the semiconductor light source travelling along the optical axis changes direction toward the at least one phosphor layer after being reflected from at least one of the substrate and the adhesive material.
