Abstract: A light-emitting module includes: a base body including electrical conductor wirings; a light-emitting element disposed on the base body and electrically connected to the electrical conductor wirings; a light reflection film disposed on an upper surface of the light-emitting element; and a half mirror disposed on a light extraction surface side of the light-emitting element and spaced apart from the light-emitting element. A spectral reflectance of the half mirror under perpendicular incidence at a wavelength longer than a peak emission wavelength of a light emitted from the light-emitting element is greater than a spectral reflectance of the half mirror under perpendicular incidence at the peak emission wavelength.

Abstract: A semiconductor light emitting device including a substrate, an electrode and a light emitting region is provided. The substrate may have protruding portions formed in a repeating pattern on substantially an entire surface of the substrate while the rest of the surface may be substantially flat. The cross sections of the protruding portions taken along planes orthogonal to the surface of the substrate may be semi-circular in shape. The cross sections of the protruding portions may in alternative be convex in shape. A buffer layer and a GaN layer may be formed on the substrate.
