Abstract
The present disclosure relates generally to a “clocking” mechanism that give customers the flexibility to adjust light output distribution of luminaires to a desired level. The “clocking” mechanism gives the flexibility to adjust a position of a retainer ring of a LED system with respect to a mounting module that includes a heat sink adapter housing.
Claims19
A light system comprising:
- a driver compartment assembly;
- a heat sink adapter housing fixed to the driver compartment assembly, the heat sink adapter housing defining a plurality of openings that are each internally threaded;
- a light engine adapted to be removably attached to the heat sink adapter housing, the light engine including:
- a baseplate;
- optics coupled to the baseplate;
- a retainer ring removably mounted to the baseplate, the retainer ring including a plurality of mounting regions circumferentially positioned thereabout, wherein the plurality of mounting regions each include a plurality of discrete openings spaced apart equally in an arcuate array, each of the plurality of mounting regions corresponding to a circumferential flange segment of the retainer ring, the circumferential flange segments of the retainer ring being separated by projections, the plurality of discrete openings being defined through the circumferential flange segments, respectively;
- and
- a lens having an outer flange disposed between the baseplate and the retainer ring, the lens at least partially surrounding the optics to enclose the optics on the baseplate;
- wherein the retainer ring is rotatable relative to the heat sink adapter in discrete increments via the plurality of discrete openings, the plurality of discrete openings of the plurality of mounting regions each respectively corresponding to one of the plurality of openings of the heat sink adapter, wherein the optics rotate with the retainer ring to change the light distribution illumination direction emitted by the optics.

A light engine comprising:
- a baseplate;
- optics coupled to the baseplate;
- a retainer ring attached to the baseplate;
- a heat sink adapter housing removably mounted to the retainer ring;
- and
- a lens having an outer flange disposed between the baseplate and the retainer ring, the lens at least partially surrounding the optics to enclose the optics on the baseplate;
- wherein:
- the retainer ring includes four separate mounting regions circumferentially positioned thereabout, each of the four separate mounting regions corresponding to a circumferential flange segment of the retainer ring, the circumferential flange segments of the retainer ring being separated by projections, and
- the retainer ring and the optics are configured to rotate together relative to the heat sink adapter housing to change the light distribution illumination direction emitted by the optics.

A light system defining a central axis, the light system comprising:
- a driver compartment assembly;
- a heat sink adapter housing fixed to the driver compartment;
- a light engine adapted to be removably attached to the heat sink adapter housing, the light engine including:
- a baseplate;
- optics coupled to the baseplate;
- a retainer ring removably mounted to the baseplate;
- a lens having an outer flange disposed between the baseplate and the retainer ring, the lens at least partially surrounding the optics to enclose the optics on the baseplate;
- at least one mounting region having at least eight discrete openings separated by no more than 10 degrees with respect to the central axis, the at least one mounting region being defined by one of the retainer ring and the heat sink adapter housing;
- and
- at least one opening defined by the other one of the retainer ring and the heat sink adapter housing, the at least one opening being internally threaded and corresponding to the at least one mounting region;
- wherein the retainer ring is rotatable relative to the heat sink adapter housing about the central axis, the retainer ring being rotatable in discrete increments via the at least eight discrete openings, the at least eight discrete openings of the at least one mounting region corresponding with the at least one opening, wherein the optics rotate with the retainer ring to change the light distribution illumination direction emitted by the optics.
