Abstract: A linear light fixture can include a housing that includes at least one wall that forms a cavity. The linear light fixture can also a light board having multiple light sources disposed thereon, where the light sources are arranged in a linear fashion with respect to each other on the light board, where the light board is disposed within the cavity of the housing. The linear light fixture can further include a lens slidably disposed within a receiving feature of the housing. The linear light fixture can also include a first auxiliary optical member disposed within cavity of the housing, where the first auxiliary optical member includes a first body having a first end and a second end, where the first body includes a light diffusion film. The first auxiliary optical member can fill a first gap between the lens and a first side wall of the housing.

Abstract: A luminaire can comprise an optic that extends lengthwise within a linear cavity of a frame of the luminaire. The optic can comprise a diffuser, such as a sheet of diffusing acrylic material, for example. The optic can have edges located at opposing ends of the linear cavity. The luminaire can comprise a cover for each of the two ends of the linear cavity. The covers can cover the edges of the optic, so that at each cavity end, there is an overlap between the optic and the cover. The overlap can provide a gap that compensates for thermal expansion and contraction of the optic relative to the frame, which may have a metal composition. One or more magnets can removably attach the cover to the frame of the luminaire.

Abstract: A luminaire can comprise a frame that provides a cavity for emitting illumination towards a space to be illuminated. A light source, such as a row of light emitting diodes, can emit light into the cavity. The cavity can extend lengthwise between two end caps of the frame that are located at opposing ends of the luminaire. The frame can further comprise two bridges that are located adjacent the end caps, one at each end of the frame. Two rails that extend on opposing sides of the cavity can connect the two bridges to one another. A system of grooves and protrusions can interlock the rails to the bridges. A system of standardized interchangeable components that facilitates rapid manufacture of custom luminaires can comprise the bridges, the rails, and the end caps.
