Patent ID: 7960747

Claim:
A light emitting device comprising: a light emitting element configured to emit light along a light emitting axis; an optically transparent sealing resin having a shape including a pair of faces opposed to each other with the light emitting axis of the light emitting device interposed between the pair of faces, the sealing resin located adjacent the light emitting element and including a wavelength converting material; and a reflective film located adjacent at least one of the pair of opposed faces of the sealing resin, wherein the reflective film is at least one of, a white coating containing a transparent resin and a white pigment in a concentration of 23 wt % to 54 wt % and having a thickness from substantially 14 μm to substantially 50 μm, the white coating having a roughness of 5 μm or less by reducing the agglomeration of the white pigment, and at least one metallic film having a thickness of from 250 angstroms to 900 angstroms and having a maximum height Rz from 0.6 μm to 15 μm, the metallic film having a total reflection coefficient of 76% or more and made of a metal having a total reflection coefficient of 80% or more, the metallic film directly covering an adjacent surface of the sealing resin, the sealing resin being roughened so that the metallic film has a regular reflection coefficient of 0.5% to 25%.
