Abstract

1. An elongate work-light comprising at least one fluorescent lamp for anti-dazzle and high-contrast illumination of a work table, said light being arranged above half of the work table opposite the field of action in such a manner that its longitudinal axis is transverse with respect to the usual direction of view of a person sitting at the work table, and comprising a housing and a grid, in whose downwardly pointing light outlet window provided with transverse lamellae mutually parallel and transverse to the longitudinal axis of the work-light, characterised in that the transverse lamellae (201, 202; 201', 202', 203') are inclined against the horizontal in such manner that the horizontal projection (B) of each transverse lamella is greater by one overlap (y) than the horizontal distance (A) of two adjacent transverse lamellae.
