Abstract:
1. A light emitting module for generating an output light, comprising: a semiconductor light emitting unit that generates a source light; a plurality of nanophosphor particles that have diameters smaller than a half-wavelength of the output light and emit a fluorescent light corresponding to the light generated from the semiconductor light emitting unit; and a binder that holds the nanophosphor particles as a layer that covers a light emitting surface of the semiconductor light emitting unit; wherein the semiconductor light emitting unit generates an ultraviolet light, wherein the nanophosphor particles generate a visible light corresponding to the ultraviolet light generated from the semiconductor light emitting unit, and wherein the binder comprises at least one of a fluorine resin and a dimethyl silicone resin so as to cover the light emitting surface of the semiconductor emitting unit with the nanophosphor particles.
