  • Patent number: 6062704
    Abstract: Direct/indirect lighting fixtures particularly intended for recessed applications of fluorescent lighting as wall sconces or the like, the lighting fixtures of the invention combine the efficient lighting capabilities of parabolic fluorescent lighting with the aesthetic appeal of indirect lighting to produce a visually appealing effect. The luminaires of the invention combine an arcuate reflector with an illumination source mounted near one end of the reflector with an arcuate diffuser disposed over the illumination source. Both direct and indirect light thus emanates from the luminaire. The diffuser is mounted within the luminaire to mechanical light trap elements located at either end of the diffuser, the light trap elements serving the dual purposes of minimizing light leakage and mounting the diffuser. In one embodiment of the invention, the light trap elements are integrally formed with the reflector by injection molding of a polymeric material.

  • Patent number: 5988829
    Abstract: Direct/indirect lighting fixtures particularly intended for recessed applications of fluorescent lighting for small offices and similar use environments where balanced illumination for both vertical and horizontal surfaces is necessary. The lighting fixtures of the invention include general lighting luminaires as well as wall wash luminaires, the present fixtures combining the efficient lighting capabilities of parabolic fluorescent lighting with the aesthetic appeal of indirect lighting to produce a visually appealing effect within an overall environment sufficiently illuminated for productive purposes. The general lighting luminaires of the invention combine two arcuate reflectors with intersecting curvatures, the line of intersection having illumination sources disposed on each side thereof and mounted to the reflectors in proximity to the line of intersection, the luminaires further including an arcuate diffuser centered about the line of intersection of the reflectors.
