Abstract:
1. A lighting system, comprising an inner reflector extending from a proximal end to a distal end along an axis and adapted to receive light from a light source at its proximal end; an outer reflector extending from a proximal end to a distal end through which light can exit the outer reflector, said inner and outer reflectors being coupled for axial movement relative to one another over a range of relative positions between a retracted position and an extended position, wherein the reflectors are sized and the light source is positioned relative to the proximal end of the inner reflector such that in said retracted position more than about 90% of the light emitted by the light source that enters the inner reflector exits the distal end of the outer reflector without undergoing any reflection by the outer reflector or the inner reflector, and wherein the light exiting said outer reflector exhibits a progressively decreasing flood spread as the relative position of the reflectors is transitioned from said retracted position to said extended position.
