Abstract:
1. An illumination device comprising: a housing having first and second discrete portions; disposed within the housing, a sub-assembly comprising (i) at least one solid-state light emitter and (ii) a driving circuit for providing suitable current to the at least one solid-state light emitter; and disposed within the housing and at least partially surrounding and extending above the at least one solid-state light emitter, a reflective element for directing light emitted by the at least one solid-state light emitter out of the housing along an emission axis, at least the reflective element being rotatable around the at least one solid-state light emitter, wherein (i) the first portion of the housing is configured for movement relative to the second portion of the housing, the relative movement selectively connecting and disconnecting the at least one solid-state light emitter with a power source and (ii) the driving circuit comprises a high-frequency DC-to-DC converter.
