IPC: H01L25/075
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To improve the heat radiating property of a light emitting element so as to prevent the deterioration of the light emitting output of the element by forming a translucent material so that the thickness of the material becomes thinner on at least one side of a radiating surface side which is the upper surface side of leads and a reflecting surface side which is the lower surface side of the leads. SOLUTION: The thin section 13a of a translucent material 13 is formed by shaving off a radiating surface 15 on the side from which lead 12a are led out. When a heat radiating plate 16 is fitted to the thin section 13a, the plate 16 can be brought closer to a light emitting element 11 which generates heat and the leads 12a to which the heat generated from the element 11 is transmitted. Therefore, the heat generated from the element 11 can be radiated sufficiently and the deterioration of the light emitting output of the element 11 can be prevented. The other leads 12b can also prevent the deterioration of the light emitting output of the element 11, because the leads 12a also sufficiently radiate the heat in the same way as the leads 12a do.
