Abstract:
1. A solid state lamp, comprising: a heat sink with a plurality of heat fins; a solid state light source mounted on a top surface of said heat sink; a phosphor carrier on said heat sink, over and spaced apart from said light source, such that an optical cavity is formed by the space between said phosphor carrier and said heat sink top surface; and a diffuser on said heat sink, over and spaced apart from said phosphor carrier, wherein said phosphor carrier and said diffuser are substantially frusto-spherical such that said phosphor carrier and diffuser provide a double-dome structure, wherein said lamp fits within a standard size profile, and emits a substantially uniform emission pattern, wherein said solid state light source is configured such that there are no surfaces within said optical cavity to block sideways emission from said solid state light source, wherein said diffuser extends below said top surface of said heat sink such that at least some light is emitted in a downward direction when said solid state lamp is in operation.
