Abstract (en)
[origin: EP0535416A1] The present invention relates to a work lighting fixture (10) with at least one fluorescent lamp which can be suspended at a distance from the ceiling above the workplace, with which fixture at least a part of the light emerges at the top of the lighting fixture and in which light emerges from two fixture portions which are spaced from one another in the longitudinal direction of the housing. The fixture is, according to the invention, characterised in that the emergence of direct light takes place exclusively towards the top of the fixture and a glass reflector (11) is disposed at a spacing above the housing (12, 13) of the fixture, by means of which reflector a part of the light flux emerging in an upward direction from the fixture is reflected downwards in a direction towards the workplace (28). With the work lighting fixture according to the invention, a glare-free illumination of the workplace or workplaces is achieved, good shading characteristics and good contrast levels being attained at the same time. <IMAGE>
