Abstract
The lighting fixture according to the invention includes a fixture housing having a longitudinal axis and supporting a fluorescent lamp in the housing. Side reflectors are provided which extend parallel to the longitudinal axis of the housing on either side of the lamp. A plurality of cross vanes and two end vanes are positioned below and perpendicular to the longitudinal axis of the lamp. Each cross vane has a top surface of a generally V-shaped configuration and reflector surfaces extending from the top surface. The reflector surfaces are concavely curved with a radius of curvature which varies along the width of the cross vane. The end vanes also include a generally V-shaped top surface and one reflector surface with is concavely curved with a radius of curvature which varies along the width of the end vane. The cross vanes and end vanes according to the invention confine substantially all of the light to within the preferred RP-24 cut-off zone and prevent unnecessary reflections which lower efficiency.
