Abstract
A lamp comprises an enclosure having a reflective surface and an exit surface through which light is emitted from the enclosure and a base. A plurality of LEDs are located in the enclosure and are operable to emit light when energized through an electrical path from the base. The reflective surface comprises a first reflective layer applied to the enclosure and a second reflective layer over the first reflective layer. The first reflective layer is a metalized surface. The second layer comprises a transparent carrier such as silicone mixed with a reflective media such as TiO2, Barium Sulfate and/or ZnO or silver.
