Abstract:
A light-emitting apparatus package of the present invention includes (i) an electrically insulated ceramic substrate, (ii) a first concave section formed in the direction of thickness of the ceramic substrate so as to form a light exit aperture in a surface of the ceramic substrate, (iii) a second concave section formed within the first concave section in the further direction of thickness of the ceramic substrate so that one or more light-emitting devices are provided therein, (iv) a wiring pattern for supplying electricity, which is provided in the first concave section, and (v) a metalized layer having light-reflectivity, which is (a) provided between the light-emitting device and the surface of the second concave section of the substrate, and (b) electrically insulated from the wiring pattern. On the account of this, the light-emitting apparatus package in which heat is excellently discharged and light is efficiently utilized and a light-emitting apparatus in which the light-emitting apparatus package is used can be obtained.
