Abstract
A bidirectional lighting system includes a housing having a planar base and a stringer connected to end plates by a chassis. The chassis carries a bracket for light sockets and asymmetric reflectors. The edges of the base, the end plates and the stringer define a pair of windows. One light source and an associated asymmetric provide up light illumination through one of the windows and the other light source and its associated reflector provides wall wash illumination of an adjacent wall through the other window.
Claims20
A bidirectional lighting system for use in illuminating a room, the lighting system comprising:
- (a) a fixture housing,
- (b) means for mounting the housing in the room at an elevation beneath a ceiling surface and at a location adjacent to and spaced from a wall surface,
- (c) an up light source,
- (d) means for energizing the up light source operatively connected to the up light source,
- (e) means for mounting the up light source within the housing in an operative position for emitting light radiation upwardly toward the ceiling,
- (f) up light reflector means mounted within the housing for reflecting light radiation only from the up light source toward the ceiling surface,
- (g) a wall wash light source,
- (h) means for energizing the wall wash light source operatively connected to the wall wash light source,
- (i) means for mounting the wall wash light source within the housing in an operative position for emitting light radiation toward the adjacent wall surface, and
- (j) wall wash reflector means mounted within the housing for reflecting light radiation only from the wall wash light source toward the adjacent wall surface and for distributing the reflected light radiation on the adjacent wall surface above, below and at the elevation of the housing, the light radiation emitted from the wall wash light source and the light radiation reflected from the wall wash reflector means providing uninterrupted wall wash illumination, whereby the room is supplied with both up light ceiling illumination and wall wash illumination.
A bidirectional lighting system fixture for a room, the room having a ceiling surface, a floor surface and a wall surface, the fixture including a housing, means for mounting the fixture within the room at a location spaced from the ceiling surface and spaced from the wall surface, the housing having a first window means facing the ceiling surface for defining a light passage for transmission of light upwardly against the ceiling surface, the housing having a second window means facing the wall surface for defining an unobstructed light passage for transmission of light against the wall surface, the wall surface having a height extending substantially from the ceiling surface to the floor surface, an up light source associated with the first window means, a first asymmetric reflector means associated with the up light source and the first window means for directing light only from the up light source through the light passage of the first window means toward the ceiling surface, a wall wash light source associated with the second window means, a second asymmetric reflector means associated with the wall wash light source and the second window means for directing light only from the wall wash light source through the light passage of the second window means toward a wall surface and for distributing light from the wall wash light source the continuously over the entire height of the wall surface.
A lighting system for illuminating a room, the lighting system comprising an elongate housing, the housing including a substantially planar base and a pair of substantially planar end plates lying in planes perpendicular to the plane of the base, the housing further including substantially planar chassis means associated with each end plate for interconnecting the base to the associated end plate, means fixing the chassis means to each end plate, the chassis means including a flange extending perpendicular to the plane of the chassis, the base including an internal channel, the flange including an aperture in registration with the channel, the housing including fastener means projecting from the channel through the aperture, the fastener means securing the flange to the base.
