Claim:
1. A solid state light source, comprising: a light emitting diode (LED); a heat sink with said LED in thermal contact with said heat sink; an integral fan configured to reduce the convective thermal resistance of at least some lamp elements; at least one electrical contact configured to pass through said integral fan so that an electrical signal applied to said at least one electrical contact is supplied to said LED; a diffuser dome on said heat sink and over said LED; and a phosphor carrier on said heat sink and over said LED, said phosphor carrier separate from and at least partially within said diffuser dome; said heat sink shaped to define at least two inlets, at least one of which opens adjacent to said LED and inside said phosphor carrier, such that said fan flows cool air from outside said light source into said phosphor carrier via said at least one inlet adjacent to said LED.
