Abstract

Lamps, in particular lamps having elongated fields for illuminating working spaces, must have minimum requirements for glare limitation which is determined by the screening angle ( alpha ). Because of the prescribed lamp dimensions, it is not possible to achieve the required minimum screening angle in modern lamps of this type. In order to achieve a sufficiently large screening angle ( alpha ) with such lamps, it is proposed to provide the cover plate (A1, A2), which seals the light exit opening and is made from transparent material, with rim regions (1, 5) which have a prismatic profiling of suitable dimensioning, by means of which the screening angle ( alpha ) is appropriately enlarged. In a further development, the cover plate (A2) can additionally have on the inside a central region (3) with prismatic profiling of appropriate dimensioning in order to achieve a deep indentation in the light distribution curve (LVK2) in the angular range about 0 DEG . <IMAGE>
