PURPOSE: A lighting device is provided to reduce the diffuser beads contents in the resin; to reduce the CIE(Identical Color Coordinate), CRI, and the content of fluorescent substance to the flux; and to reduce the color coordinate failure rate depending on the thickness deviation. CONSTITUTION: A light excimer is formed with the light-transmissive material, and comprises a hemispheric parent(110) and a plurality of diffusate(111). The hemispheric parent forms an opening part in the lower part to cover the light emitting device, and includes at least one fluorescent substance. The hemispheric parent comprises the light-transmissive material Polymer which is able to transmit the light emitted from the light emitting device, and forms a mixing space in the internal space. The diffusate is formed in the hemispheric shape in the inner side of the parent, and is comprised of one among the UV resin, and the resin of the acryl, silicon, and urethane. |
