<P>PROBLEM TO BE SOLVED: To provide a light emitting diode which has such a structure that a light emitting element and a reflection surface are arranged opposite to each other, and which does not suffer from a decline in reflectivity due to the occurrence of wrinkles on the reflection surface, separation of a reflection film, etc., at the time of hardening a resin which fills up a space between the light emitting element and the reflection surface in manufacturing the light emitting diode and which has a long life and a high durability and has a high light use efficiency. <P>SOLUTION: A lead frame consists of a concave surface reflector formed of a heat-resistant resin such as a liquid-crystal polymer resin with the light emitting element mounted in a concave space of the concave surface reflector. The lead frame is so arranged that the light emitting element and the reflection surface may face each other. A space between the light emitting element and the concave surface reflector is filled up with a transparent epoxy resin, specifically, a cationic polymerization type transparent epoxy resin, so as not to deteriorate the reflection characteristics of a metal reflection layer formed on the surface of the concave surface reflector. Due to this structure, the reflection surface is completely protected against external mechanical shock and thermal shock by the heat resistant resin. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
