Claim Text:
1. A light emitting device comprising: a ceramic substrate having a primary surface; a plurality of LED chips positioned around a center of the primary surface of said substrate; a plurality of wires for connecting the plurality of LED chips with each other, each of said plurality of wires being directly connected between two of the plurality of LED chips; a resin frame formed on the primary surface of said substrate and provided annularly so as to surround a mounting area in which the plurality of LED chips are provided, said resin frame having light reflectivity, and wherein the resin frame has a circular shape in a top view and a dome shape in a cross-sectional view; a sealing resin provided on the mounting area and inside said resin frame, and wherein the top of said sealing resin is higher than the top of said resin frame; an anode-side electrode land and a cathode-side electrode land which are electrodes to be connected to an external voltage supply, and are electrically connected to the plurality of LED chips, said anode-side electrode land and said cathode-side electrode land being provided on the primary surface of said substrate and outside said resin frame; and an electrode wiring pattern on the primary surface of the substrate including (i) an anode pattern extending from the anode-side electrode land to a portion under said resin frame, and (ii) a cathode pattern extending from the cathode-side electrode land to the other portion under the resin frame, so as to electrically connect the plurality of LED chips to the anode-side electrode land and the cathode-side electrode land.
