Patent ID: 7339201

Claim:
A light emitting diode comprising a casing having a concave cavity defined therein, a reflecting surface formed by depositing a metallic layer on a surface defining the concave cavity, and a lead having a light emitting element fitted thereto so as to confront the reflecting surface, wherein a cationic polymerization type transparent epoxy resin is filled within the concave cavity of the casing, wherein the lead is engaged in a groove formed on an upper end face of the casing, a light curable epoxy resin is filled in the groove, where the lead is engaged, to a level flush with the upper end face of the casing, and the light curable epoxy resin is cured by irradiation of ultraviolet rays of light to fix the lead in the groove in the casing, and further, the cationic polymerization transparent epoxy resin is filled to a level flush with the upper end face of the casing, and wherein the cationic polymerization type transparent resin is cured while a sandwich structure is formed by the cationic polymerization transparent epoxy resin, the reflecting surface and the casing.
