Description

The invention relates to a reflector with a split reflector, in which the reflection of light rays is solved by the reflective surface of the reflector being divided into a plurality of convex lenses assembled in a parabola.

Previously known automotive and other reflectors have a reflective surface of differently profiled, but predominantly parabolic shape, whose surface is not ideally smooth. At microscopic magnification, the individual points of this surface lose their parabolic shape, as a result of which the reflected luminous flux is unevenly dispersed. While the individual sites are backlit and cause glare due to the merging of the beams into the beams, the much larger space between these merging beams remains unlit and causes a rapid yellowing of the cone of light as the distance from the light source increases.

The above-mentioned drawbacks are eliminated by the reflector according to the invention, which is characterized in that the reflective surface of the parabolic shape consists of convex lenses, the connecting lines whose apexes form a parabolic surface, the base of each of these lenses being polygonal and the individual lenses abutting each other. The size, number and rounding of these lenses may vary.

The reflective surface of the reflector according to the invention is achieved by avoiding the formation of beams. Due to convex lenses assembled into a parabola, these are "combed" into individual rays. Each lens reflects a complete beam of light. By overlapping the light beams reflected from the individual convex lenses into an overall light beam, a very dense beam pattern is achieved. The light appears to the oncoming as white, less dazzling. The ideal surface smoothness of the reflective surface, which cannot be achieved by any technology, is thus replaced by multiple overlapping of the scattered luminous flux, thereby achieving uniform light scattering without incurring interface losses. The intensity, scattering and glare of the overall light cone can be determined by the ratio of the size, quantity and rounding of the lenses.

The reflecting surface of the reflector according to the invention is shown in the attached drawing. The plan view of FIG. 1 shows one of the possibilities of dividing the reflective surface 1 by convex lenses 2 whose base is in the shape of a polygon 3. The periphery of the frame 4 and its profiling can always be adapted to the desired purpose. FIG. 2 is a cross-sectional side view of the reflective surface 1, whose raised lenses 2 are intentionally magnified so as to be clear.

The reflective surface of the reflector 1 according to the invention can be molded, the plan view of the lenses 2 being a network of polygons 3 ^; so that no loss points are formed between the individual lenses.

The use of this reflector is possible wherever the original reflector types were used before. In addition, it can also be used for other special purposes with the appropriate treatment described in the fourth paragraph of the description. Here, too, the ideally smooth surface of the reflective surface of the convex lenses is not envisaged. Due to this rounding, the lenses fulfill their purpose even with the existing surface smoothness quality, i.e. to prevent unwanted light beams.
