1. A lighting system, comprising:
a lens assembly including a lens having a light output surface being spaced apart along a central axis from a light input surface, the lens further having a lateral surface being spaced apart around the central axis and having a frusto-conical shape extending between the light input and output surfaces of the lens, the lens being configured for causing some light passing into the lens through the light input surface to be diverted toward the lateral surface;
a light source being located adjacent to the light input surface of the lens, the light source including a semiconductor light-emitting device and being configured for generating light being directed through the light input surface into the lens;
a reflector having another frusto-conical shape, the reflector being spaced apart around the central axis and extending between the light input and output surfaces of the lens, the reflector having a reflective surface that faces toward the lateral surface of the lens, the reflector also having an opposite surface that faces away from the lateral surface of the lens; and
a potting material facing toward the opposite surface of the reflector, the potting material being spaced apart from the opposite surface of the reflector so as to form a gap.
