    摘要: A screen light comprises a substantially box-shaped housing having a light outlet opening, a fluorescent lamp arranged in the housing centrally in its upper region, and elements for subdividing the light outlet opening into substantially three fields including a central field and two lateral fields, so that a part of a light flux produced by the fluorescent lamp exits primarily directly in the central field, while two parts of the light flux exit from the lateral fields secondarily by reflection.

    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.
