<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of miniaturizing a substrate and a reflecting plate, and to provide an assembly of the light-emitting device. <P>SOLUTION: The light-emitting device 1 has: a light-emitting element 2; the substrate 3 where the light-emitting element 2 is packaged; the reflecting plate 4 arranged on the substrate 3; and a screw member 5 fixing the reflecting plate 4 and the substrate 3. The substrate 3 has: a first surface 7; a second surface 8 at a side opposite to the first surface 7; and a fitting section where the light-emitting element 2 is packaged. The reflecting plate 4 has: a third surface 9 in contact with the first surface 7; a fourth surface 10 at a side opposite to the third surface 9; and an opening 6 that penetrates the reflecting plate 4 and is open to the third surface 9 and the fourth surface 10. In the opening 6, an open area at the side of the fourth surface 10 of the reflecting plate 4 is larger than that at the side of the third surface 9 of the reflecting plate 4. The screw member 5 penetrates the first surface 7 of the substrate 3 and the third surface 9 of the reflecting plate 4 toward a region near the opening 6 where the opening 6 of the reflecting plate 4 is not formed from the second surface 8 of the substrate 3, and fixes the substrate 3 and the reflecting plate 4. <P>COPYRIGHT: (C)2009,JPO&INPIT |
