  • Patent number: 5418694
    Abstract: A gate for a lamp which is particularly suited for illuminating rectangular objects comprises a holding element defining a light-passage opening which can be mounted on the lamp. Four gate wings are mounted on the holding element about the light-passage opening for defining a gate opening having substantially the approximate shape of an even-leg, or isosceles, trapezoid.

  • Patent number: 5313380
    Abstract: A lighting assembly has a grid (5) arranged to be adjustable at a light outlet of a housing (1). In one embodiment, there is a plurality of grids (4, 5, 6), preferably arranged one behind the other in a direction of light rays, which are movable relative to one another. When the position of a grid (5) of such a lamp assembly is adjusted, a light emission angle of the lighting assembly is adjusted. When, in a preferred embodiment, slats of the grids are arranged in true alignment to one another, a light emission angle is relatively small. By adjusting the grids, for example by one half step adjustments relative to one another, the light emissions angle is enlarged accordingly. Thus, a directional effect can be achieved without a focussing effect, even with the use of fluorescent tubes.
