Abstract

Linear luminaires that asymmetrically distribute emitted and reflected light are presented. These luminaires have single or twin unit fluorescent lighting and optional uplighting. Each includes an elliptical baffle assembly and at least one independently adjustable reflector enclosed within the housing of the luminaire. The adjustable reflector is adjustable through at least about 15° of rotation and is at least partially hidden from view by the housing and baffle assembly. The luminaires can be surface mounted, suspended, or cantilever mounted, and include wireways to permit wiring to be run discreetly inside and through adjacent asymmetric distribution luminaires.
