Abstract:
1. An apparatus for selectively emitting one or more of a plurality of wavelength distributions of radiation, comprising: a primary UV radiation source, disposed in a housing, wherein said primary UV radiation source produces a primary wavelength distribution; at least one wavelength-transforming material, deposed external to the envelope of said primary UV radiation source, that in response to irradiation by said primary UV radiation source, emits a transformed radiation; a selection mechanism deposed internal to the housing, wherein said selection mechanism is substantially non-removably coupled to the housing; wherein said selection mechanism places at least one selected portion of said at least one wavelength-transforming materials relative to said primary UV radiation source; a reflector unit disposed proximate to said primary UV radiation source wherein said reflector unit directs the primary wavelength distribution radiation from said primary UV radiation source onto said at least one wavelength-transforming material; and wherein said reflector unit is also deposed relative to said primary UV radiation source such that non-selected portions of said at least one wavelength-transforming materials are shaded from irradiation by said primary UV radiation source.
