Abstract: A single edge lit lighting module is disclosed which produces tailored light distributions valuable in many illumination applications. The light distributions attainable using the invention include, but are not limited to, symmetric and asymmetric batwing distributions, asymmetric distributions for perimeter lighting and symmetric distributions. The invention's unique single edge lit construction provide the means for achieving this without need for conventional two lit edges and within a compact form factor with narrow width, particularly well-suited for linear lighting fixtures. Various embodiments also provide means for adjusting light distributions dynamically to control light output characteristics by controlling the input signals to the LED board included in the assembly.

Abstract: A canopy for use with a ceiling connector mountable at a designated ceiling location to define a mounting end region thereon, includes a body securable to the mounting end region by a rotationally operable connector, wherein the body is configured to form a mounting interface with the mounting end region to block perceptible relative rotation therebetween about a rotation axis defined by the connector by forces associated therewith, wherein the mounting interface is defined by at least one first engagement surface on the canopy configured to be in contact with at least corresponding second engagement surface on the mounting end region.
