Claim Text:
1. A lighting device comprising: a base end; electrical contacts associated with the base end; a light-transmissive end; at least one solid state light emitting source; a reflector comprising a cup-shaped body including (i) a reflective surface, (ii) at least one aperture arranged to enable transmission of light emissions of the at least one solid state light emitting source through the at least one aperture, and (iii) a light-transmissive opening arranged to permit transmission of light reflected by the reflector toward the light-transmissive end; at least one lumiphoric material that is spatially segregated from the at least one solid state light emitting source, that is arranged to receive at least a portion of the light emissions of the at least one solid state light emitting source, and that is arranged to emit lumiphor-converted light emissions toward the reflector; and a lens proximate to the light-transmissive opening of the reflector; wherein the reflector is arranged to reflect lumiphor-converted light emissions toward the light-transmissive end; and wherein the lighting device comprises at least one of the following features (a) or (b): (a) the lighting device includes a support structure that is distinct from the lens and is arranged to support the at least one lumiphoric material between the lens and the at least one aperture, wherein the support structure and the at least one lumiphoric material are spatially separated from and devoid of contact with the lens; and (b) the lighting device includes a heat sink arranged external to the lens, arranged in conductive thermal communication with the at least one lumiphoric material, and arranged to dissipate heat from the at least one lumiphoric material to an ambient air environment, wherein the heat sink includes a screw or movable element extending from a lumiphoric material support structure through the lens, and movement of the heat sink is arranged to cause movement of the at least one lumiphoric material.
