Abstract
A luminaire, such as an indirect linear luminaire, is provided with a floating reflector assembly tied directly to securement points in the luminaire housing. The reflector assembly has a reflector element with tie down openings which overlay the reflector securement points and compliant spring-like retaining clips which overlap the tie down openings and which are secured at their center portion to the underlying securement points by a screw fastener. The width of the retaining clips are narrower than the tie down opening such that the center portion of the retaining clips can be drawn into and contact the housing securement points to provide good electrical grounding. The pressure contact of the retaining clips holds the reflector down yet permits it to float within the housing when the housing is distorted, such as by twisting, thereby avoiding distortion of the reflector.
