ABSTRACT:
A fluorescent indirect lighting fixture of the hidden source offset reflector type incorporates a novel reflector mounting system which provides advantages of extended uniform "wash" illumination with unusual concealment of the light source from direct view, along with extremenly easy reflector installation and replacement. The reflector, formed to the required special curvature from a thin sheet of suitable metal such as high purity aluminum, is sprung into place between two opposite edges of a window opening in the metal fixture housing in a tongue-and-groove type engagement along the two edges where it is retained in place by the resilience of the reflector with no need for adhesives, screws or other fastenings. Illumination coverage and lamp concealment are both maximized by configuring the reflector and its mounting system uncompromisingly such that both of the straight end regions of the curved reflector extend smoothly and fully to a plane flush with the surrounding ceiling or wall surface.
