Abstract

A light emitting device including a housing, a plurality of heat-sinks adjoined to the housing and insulated from each other, a bottom surface of the heat-sinks being exposed to the outside, a light emitting diode mounted on at least one of the heat-sinks via a conductive adhesive, and a molding member encapsulating the light emitting diode and including thermosetting resin, in which a fluoride luminophore including I and IV group elements with fluorine and other luminophore are dispersed in the molding member, and the luminophores are configured to absorb at least a portion of light emitted from the light emitting diode and emit light having a wavelength different from that of the absorbed light.
