Abstract
A semiconductor light emitting device includes a substrate having a wiring pattern formed thereon, and a semiconductor light emitting element mounted on one main surface of the substrate and electrically connected to the wiring pattern. The substrate has, on the one main surface, a serrated structure reflecting at least part of light emitted from said semiconductor light emitting element to the substrate, to a direction perpendicular to the one main surface.
Claims15
A semiconductor light emitting device, comprising:
- a substrate provided with a wiring pattern;
- and
- a semiconductor light emitting element mounted on a top surface of said substrate and electrically connected to said wiring pattern;
- wherein
- said substrate has, on said top surface, a serrated structure for reflecting at least part of light, emitted from said semiconductor light emitting element to said substrate, in a direction perpendicular to said top surface so that said at least part of the light is reflected toward a side of the substrate on which the semiconductor light emitting element is mounted.
