Abstract: A retainer ring for a light fixture includes a cylindrical main body section that defines a cylindrical axis, and an inner retaining flange that extends radially inward from a distal end of the main body section. The inner retaining flange extends substantially about a circumference of the distal end. One or more coupling features extend radially inward from the retainer ring. A customization kit for a light engine that defines an optical axis includes a retainer ring configured to couple with the light engine, and two or more primary optics that are mechanically compatible with the light engine, and retainable to the light engine with the retainer ring. When the retainer ring couples with the light engine, a cylindrical axis of the retainer ring coincides with the optical axis.

Abstract: A light fixture includes a housing having sidewalls that define a manifold aperture, extending from upper to lower edges of the manifold aperture. The housing includes first coupling features. The light fixture includes at least one adapter plate with second coupling features that removably couple with the first coupling features. The adapter plate defines an adapter plate aperture. At least one light emitting engine removably couples with the adapter plate such that emitted light passes through the adapter plate aperture. The light fixture further includes a baffle that includes at least one baffle cell. The baffle cell includes an upper baffle edge that defines: an upper baffle aperture through which light emitted by the light engine passes, a lower baffle edge that defines an output aperture for the emitted light, and a baffle cell wall that extends from the upper baffle edge to the lower baffle edge.

Abstract: A baffle for use in a light fixture that includes one or more light emitter positions includes one or more upper edges, each of the upper edges encircling a light emitting aperture and lying within an upper region. The baffle also includes one or more lower edges that correspond in number with the one or more upper edges, each lower edge lying within a lower region, and encircling an output aperture. Plan view shapes of the upper and lower edges form closed shapes that are devoid of angles. The baffle further includes an interior baffle surface that extends downwardly from each of the upper edges to corresponding ones of the lower edges. The interior baffle surface is continuously and downwardly concave from each of the upper edges to each of the lower edges, and is devoid of angles.
