Abstract
According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, an LED mounted to the circuit board that is configured to emit light with an angular CCT deviation, a lens assembly mounted to the circuit board over the LED and configured to receive the light emitted from the LED and reduce the angular CCT deviation of the light received from the LED to make a color temperature of the light received from the LED more uniform, and an elastomer encapsulating at least part of the circuit board that is separate and distinct from the lens assembly.

1-20. (canceled)
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 emissions 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 the light emissions 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;
- and
- a potting material being interposed between the reflective surface of the reflector and the lateral surface of the lens, the potting material having a different refractive index than a refractive index of the lens.
A lighting process, comprising:
- providing a lighting system having 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 lighting system also having a light source for generating light emissions and being located adjacent to the light input surface of the lens, the light source including a semiconductor light-emitting device, the lighting system further including 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, and the lighting system having a potting material being interposed between the reflective surface of the reflector and the lateral surface of the lens, the potting material having a different refractive index than a refractive index of the lens;
- causing the light source to generate the light emissions being directed through the light input surface into the lens;
- and
- causing the lens to divert, toward the lateral surface, some light emissions after passing into the lens through the light input surface.
