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.

Claims (9)

1. An electric apparatus comprising:

a radiator apparatus;

a light-emitting apparatus package including (i) a ceramic substrate located on said radiator, (ii) a plurality of light-emitting elements mounted on a central region of a top surface side of the ceramic substrate, (iii) first and second wiring patterns formed on the top surface side of the ceramic substrate and electrically connected to the light-emitting elements, the first wiring pattern extending, in a first direction, to a peripheral region of the ceramic substrate and the second wiring pattern extending, in a second direction opposed to the first direction, to the peripheral region;

a first wiring substrate section located right above the peripheral region of the ceramic substrate, for electrically contacting with the first wiring pattern; and

a second wiring substrate section located right above the peripheral region of the ceramic substrate, for electrically contacting with the second wiring pattern.

2. The electric apparatus of claim 1 , further comprising:

a first terminal electrically connected to the first wiring pattern and contacting with the first wiring substrate section; and

a second terminal electrically connected to the second wiring pattern and contacting with the second wiring substrate section.

3. The electric apparatus of claim 2 , wherein the first and second terminals contact with the first and second wiring substrate sections via a conductive adhesive agent, respectively.
