ABSTRACT:
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.
