Abstract:
A LED lamp has a non-optically transmissive base connected to an optically transmissive enclosure. A LED assembly emits light when energized through an electrical path from the base. A portion of the heat sink and lamp electronics extend from the base and into the enclosure such that at least an upper portion of the heat sink extends into the interior volume defined by the enclosure. The LED assembly is supported on top of the heat sink such that the LEDs are disposed in the volume of the enclosure. An optic element extends over the LEDs and at least the portion of the heat sink. The size of the non-optically transmissive base of the lamp is reduced relative to the optically transmissive enclosure such that a greater ratio of optically transmissive view space to non-optically transmissive base is provided.
