Abstract:
A light emitting apparatus and a production method of the apparatus are provided that can emit light with less color unevenness at high luminance. The apparatus includes a light emitting device, a transparent member receiving incident light emitted from the device, and a covering member. The transparent member is formed of an inorganic material light conversion member including an externally exposed emission surface, and a side surface contiguous to the emission surface. The covering member contains a reflective material, and covers at least the side surfaces of the transparent member. Substantially only the emission surface serves as the emission area of the apparatus. It is possible to provide emitted light having excellent directivity and luminance. Emitted light can be easily optically controlled. In the case where each light emitting apparatus is used as a unit light source, the apparatus has high secondary usability.
