Patent abstract
A light emitting diode comprising: a base substrate having a pair of electrodes; a reflection cup installed on the base substrate; a light emitting element arranged at a bottom of the reflection cup; and a resin sealant enclosing the light emitting element; wherein the light emitting element is electrically connected to the electrodes through an opening formed in the bottom of the reflection cup; wherein the reflection cup comprises a film body held in a cup shape and a metal film formed on a surface of the film body. This construction makes the control of light directivity easy and can produce light with a narrow directivity.
