摘要：
A lighting fixture suspendable from a ceiling above a working area for illuminating a workplace includes two fixture parts spaced from each other in longitudinal direction and each radiating light generated by at least one fluorescent lamp exclusively toward the top side thereof. Arranged above and at a distance to the first and second fixture parts is a reflector by which a fraction of upwardly radiated incident light rays is downwardly reflected in direction of the workplace.
