Abstract
According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, a light emitting diode (LED) mounted to the circuit board and configured to emit light, a lens disposed over the LED having a bottom surface facing the circuit board, a top surface opposite the bottom surface, and a lateral surface between the top and bottom surfaces, and an elastomer encapsulating at least part of the circuit board. The elastomer may not be in contact with at least part of the lateral surface of the lens so as to form a gap between the elastomer and the lateral surface of the lens.
Claims18
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, a portion of the potting material being spaced apart from a portion of the opposite surface of the reflector so as to form a gap, and another portion of the potting material being in contact with another portion of the opposite surface of the reflector.

- wherein a portion of the reflective surface of the reflector is spaced apart from a portion of the lateral surface of the lens forming a gap, and
- wherein a portion of the gap is filled by a potting material.
