Light emitting diode with reflection cup |
摘要 |
A light emitting diode of this invention comprises: a base substrate having a pair of electrode portions; a light emitting element mounted on the base substrate and electrically connected to the electrode portions; a reflection cup placed on the base substrate to surround the light emitting element; and a resin sealant sealing the light emitting element; wherein the base substrate is formed with a raised portion on an upper surface thereof and the light emitting element is placed on a top surface of the raised portion so that side surfaces of the light emitting element are situated higher than a lower end of the reflection cup. With this construction, light emitted from the side surfaces of the light emitting element can be extracted efficiently in an upward direction.
