Abstract

Each fluorescent lamp (1) is assigned a louvre system consisting of a parabolic longitudinal reflector (2) and numerous crossblades (3) consisting in each case of two parabolic limbs. The aim is for the light to be brought from the lamp indirectly in an oblique direction onto a workplace via the crossblades. So that light cannot be emitted directly between the crossblades (3), the gaps are covered, on the one hand by cover plates (4a) parallel to the lamp which adjoin in each case the base of the crossblades, and over the remainder by cover plates (4b) which are likewise parallel to the lamp but are arranged in an upper plane at a slight distance from the lamp. Without appreciably changing the basic design of the lighting fixture, it is possible to determine the extent and direction of the indirect light reflection by a wider or narrower construction of the upper cover plates or by overlapping. For the rest, it is also possible for the lower cover plates (4a) to be used to emit light by radiating (6) upwards via an opening (2a) between the longitudinal reflectors. <IMAGE>
