Abstract
A task lighting assembly having a task lighting fixture secured in overlying relationship with respect to a work station, a building wall member disposed adjacent to the lighting fixture and adjacent to the work station and the lighting fixture having an upper wall, a front wall depending from the upper wall and an inwardly projecting lower wall projecting from the front wall. At least one light source receiving recess is defined between the walls. A light discharging opening is disposed between the lower wall and the building wall member. The lower wall is of sufficient length so that no significant portion of the light emitted by a light source in the recess will travel directly downwardly to illuminate the work station. The fixture preferably has no lens. The work station is illuminated primarily through reflected radiation. The undersurface of the upper wall preferably has a reflectance of at least about 80 percent. A task lighting fixture suitable for use in the above-described assembly.
