Patent number: 6422720Abstract: A retrofit luminaire assembly for mounting in an existing canopy fixture housing and methods of installing same. The retrofit luminaire assembly includes a planar panel having electrical control elements mounted to an upper surface of the panel. A lamp is received in a lamp socket mounted to the panel with a light-emitting section of the lamp extending away from a lower surface of the panel. A lens is mounted to the lower surface of the panel for enclosing the light-emitting section of the lamp. The panel preferably has a pair of oppositely directed pivot members which are adapted to engage with inwardly directed flanges of the canopy fixture housing to removably and pivotally support the panel for movement between a vertical, inoperative position and a horizontal, operative position. Flange extension members are provided to engage the inwardly directed flanges of the fixture housing to reduce the size of the opening for larger fixture housings to a desired common size opening.Type: GrantFiled: November 30, 2000Date of Patent: July 23, 2002Assignee: LSI Industries Inc.Inventors: Jerry F. Fischer, Robert E. Kaeser, Mark C. Reed, James P. Sferra, James G. Vanden Eynden
