Abstract

A lighting device comprises a solid state light emitter, first and second electrodes connected to the emitter, an encapsulant region comprising a silicone compound and a supporting region. The encapsulant region extends to an external surface of the lighting device. At least a portion of the first electrode is surrounded by the supporting region. The encapsulant region and the supporting region together define an outer surface which substantially encompasses the emitter. A method of making a lighting device, comprises electrically connecting first and second electrodes to an emitter; inserting the emitter into mold cavity; inserting an encapsulant composition comprising a one silicone compound; and then inserting a second composition to substantially surround at least a portion of the first electrode.
