<P>PROBLEM TO BE SOLVED: To provide a light-emitting module capable of increasing an optical output and maintaining the optical output for a prolonged term while suppressing the generation of migration. <P>SOLUTION: A polygonal-shaped metallic reflecting layer 41 is laminated on a module substrate 32 including an insulating layer 34, and positive and negative feed conductors 43 and 45 are laminated parallel to reflecting-layer edges 41a and 41b across the reflecting layer. Separations E longer than in-edge distances D among the intermediate edges 43b and 45b of the feed conductors and the reflecting-layer edges 41a and 41b adjacent to these edges are formed among the ends 43a and 45a of these feed conductors and the corners of the reflecting layer 41. A plurality of light-emitting elements 51 are mounted on the reflecting layer 41, and the adjacent mutual light-emitting elements and the light-emitting elements 51 adjacent to the feed conductors and the feed conductors 43 and 45 are connected by bonding wires 53 and 54 respectively. A frame member 56 is mounted on the substrate 32, the reflecting layer and the feed conductors are housed in the inside surrounded by an inner peripheral surface 56a having the same shape as the reflecting layer and a light-transmitting sealing member 58 is fitted in the frame member. <P>COPYRIGHT: (C)2011,JPO&INPIT |
