Abstract
Optic couplings, including optic retention rings, are described herein that require reduced tooling or no tooling for optic installation on luminaires. Briefly, a retention ring for coupling an optic to a luminaire comprises radial alignment assemblies comprising a base, and a protrusion extending from a surface of the base for engaging a coupling assembly of the optic. At least one radial locking assembly is offset from the radial alignment assemblies, the radial locking assembly comprising a vertical protrusion for engaging an aperture of the optic coupling assembly and locking rotation of the optic relative to the radial alignment assemblies.

A retention ring for coupling an optic to a luminaire comprising:
- radial alignment assemblies extending outward from a base, and a protrusion extending from a surface of the radial alignment assemblies for engaging a coupling assembly of the optic;
- and at least one radial locking assembly offset from the radial alignment assemblies, the radial locking assembly comprising a flange extending radially outward from a circumference of the retention ring and a vertical protrusion extending from the flange for passing into an aperture of the optic coupling assembly and locking rotation of the optic relative to the radial alignment assemblies.
A luminaire comprising:
- a lighting assembly, and an optic coupled to the lighting assembly via a retention ring, the retention ring comprising:
- radial alignment assemblies extending outward from a base, and a protrusion extending from a surface of the radial alignment assemblies and engaging a coupling assembly of the optic;
- and at least one radial locking assembly offset from the radial alignment assemblies, the radial locking assembly comprising a flange extending radially outward from a circumference of the retention ring and a vertical protrusion extending from the flange and passing into an aperture of the optic coupling assembly and locking rotation of the optic relative to the radial alignment assemblies.
A method of coupling an optic to a lighting assembly of a luminaire comprising:
- coupling a retention ring to the lighting assembly, the retention ring comprising radial alignment assemblies extending outward from a base, and a protrusion extending from a surface of the radial alignment assemblies for engaging a coupling assembly of the optic, and at least one radial locking assembly offset from the radial alignment assemblies, the radial locking assembly comprising a flange extending radially outward from a circumference of the retention ring and a vertical protrusion extending from the flange;
- engaging the protrusions of the radial alignment assemblies with slots of the optic coupling assembly;
- and rotating the optic until the vertical protrusion of the locking assembly passes into an aperture of the optic coupling assembly to lock rotation of the optic relative to the radial alignment assemblies.
