Abstract: The outer peripheral portion of a substrate is provided with a first peripheral edge and a second peripheral edge. The first peripheral edge is provided on the edge portion of a first upper surface of the substrate on which a light-emitting diode element is mounted. The second peripheral edge is formed either on an extension of an imaginary line connecting an edge of the light-emitting facet of the light-emitting diode element and the first peripheral edge or inwardly of the extension. The second peripheral edge is located at a position where the first peripheral edge blocks direct light from the light-emitting diode element. This configuration prevents the second upper surface of the substrate provided between the first peripheral edge and the second peripheral edge from becoming deteriorated due to the direct light.

Abstract: An LED which includes a substrate, at least one light-emitting element mounted on, and electrically connected to, the substrate, and a sealing member mounted to the substrate so as to seal the light-emitting element. The sealing member contains an inorganic material having a high contrast ratio and a high reflectivity in an amount which accords with the luminance of the light-emitting element.

Abstract: A light emitting diode has a base made of heat conductive material, a wire plate made of an insulation material and secured to an upper surface of the base. Conductive patterns are secured to the wire plate, and a light emitting diode element is secured to the base at an exposed mounting area. The light emitting diode element is electrically connected to the conductive patterns.
