Abstract: A hybrid optic includes a folded optical element with an outer reflective surface, an output surface, and a hollow core comprising a sidewall, a core output surface, and a core input opening through which light emitted by a light source enters the hollow core. A reflector element, coupled to the folded optical element, receives light from the light source, reflects a portion of the light into the hollow core and directly transmits the remaining portion of the light into the hollow core. To reduce the appearance of non-uniformities in the output light, the reflector element is diffuse and white, portions of the folded optical element are diffusely reflective, and/or a glare control diffuser is disposed on the output surface to disperse light transmitted through the core output surface of the hollow core. In this manner, the light coupling efficiency of the hybrid optic is enhanced without producing structured light.

Abstract: A bar hanger assembly is used to couple a housing to a support structure. The bar hanger assembly may include a bar hanger holder to mechanically couple the bar hanger assembly to the housing, such as a junction box, a can housing, or a frame. The bar hanger holder may define a channel to mechanically guide and support a pair of bar hangers. The bar hangers may be mechanically coupled together in a telescoping manner such that the first bar hanger is slidably adjustable with respect to the second bar hanger. The bar hanger holder and each bar hanger may physically contact one another and, in some instances, generate a compressive force to substantially reduce unwanted play. Each bar hanger may include a bar hanger head to couple the bar hanger assembly to various types of support structures, such as a T-bar, a stud, a joist, or a frame.
