Abstract
A semiconductor light-emitting apparatus is constructed by a substrate; a semiconductor light-emitting element mounted on the substrate; a wavelength-converting structure, provided on the semiconductor light-emitting element, at least an outer edge portion of the wavelength-converting structure having an uneven top surface; and a white-light reflective layer provided on the substrate to surround sidewalls of the semiconductor light-emitting element and the wavelength-converting structure. The white-light reflective layer further includes an additional transparent resin layer excluding the reflective fillers on at least the outer edge portion of the wavelength-converting structure. The additional transparent resin layer is coupled to the transparent resin layer.
