US Patent 9512969 Modular LED lamp fixtures and associated accessories

A lamp fixture includes a light emitting diode supported on a front surface of a printed circuit board. A reflector and heat sink includes a rear surface disposed adjacent the front surface of the printed circuit board and an opposing reflective surface defining a reflector dish. An aperture through the reflector and heat sink allows the light emitting diode to extend from the printed circuit board into the reflector dish. An epoxy lens is disposed over and seals the reflector surface and the light emitting diode. A assembly including a base and an inner casing extending from the base supports the printed circuit board and the reflector and heat sink. An outer casing encloses the inner casing and includes an aperture for outputting light transmitted through the epoxy lens from the light emitting diode and the reflective surface.
