An optical assembly includes a retention ring configured to couple an optic and a trim. The optic can receive light from a light source and include an optic coupler. The trim can surround the optic and direct the light away from the light source. The trim can include a trim coupler. The retention ring can tool-lessly couple with the optic and the trim. The retention ring can include an optic retention element configured to tool-lessly couple with the optic coupler to couple the optic to the retention ring; and a trim retention element spaced radially outwardly from the optic retention element. The trim retention element can tool-lessly couple with the trim coupler to couple the trim to the retention ring radially outwardly from the optic.

Optic and trim retention ring

A foldable mounting collar includes first and second collar segments. Each collar segment includes a planar annular segment that substantially subtends a semicircle, a collar flange that, when the planar annular segment is horizontal, extends vertically downward along an inner periphery of the planar annular segment, such that the collar flange forms a cylindrical portion, and two hinge flanges that, when the planar annular segment is horizontal, extend upwardly from each end of the semicircle formed by each planar annular segment. The mounting collar further includes pivot means that hingedly couple pairs of the hinge flanges of the collar segments. The second collar segment can rotate, relative to the first collar segment, through at least a polar angle range sufficient for the mounting collar to fit through an aperture having a diameter defined by the cylindrical portions of the collar flanges when both collar segments are horizontal.

Light fixture installation apparatus and methods

A retention assembly includes a body that is configured to couple with the light fixture housing through a hinge. The body forms an internal axle. The retention assembly also includes a spring. A proximal end of the spring coils about the internal axle. A distal end of the spring extends from the body, and is configured to couple with a coupling feature of the light fixture housing. When the body couples with the hinge and the distal end of the spring couples with the coupling feature of the light fixture housing, a tension within the spring exerts a torque on the body, so as to urge the body to rotate about the hinge, toward the coupling feature.
