Definitions
- the invention relates to a rotating beacon, the incandescent lamp with its filament is arranged in the focal point of the parabolic reflector, the parabolic reflector being mounted on the lower part so as to be rotatable about a vertical axis, and having a light hood.
- Warning lights with cylindrical light hood shapes are already known in practice, which have cylindrical lenses running inside in the direction of the axis of rotation. In addition to the resulting horizontal scatter, the light hood does not produce any vertical scatter.
- torus lenses are used instead of the inner cylindrical lenses. While better vertical scattering is achieved here in addition to horizontal scattering, the tooling effort is considerably more expensive. The durability of such a tool is also considerably shorter, since with the internal torus optics the necessary sharp edges in the shape wear out very quickly and the tool shape has to be revised frequently.
- a rotating beacon is known from European patent application EP-A-0 395 351, the incandescent lamp with its filament being arranged in the focal point of a parabolic reflector.
- the parabolic reflector is mounted on the lower part so that it can be rotated about a vertical axis.
- the rotating beacon has a light hood that closes this.
- this version of a rotating beacon proves to be a disadvantage that due to the use of a parabolic reflector only a narrow band of light is generated, whereby only a small warning effect can be achieved.
- a rotating beacon is known from US Pat. No. 4,839,782, which has vertical cylindrical lenses on the inside of the light hood.
- the light hood has ring prisms on its outer surface, which have cross-sections V-shaped recesses that run concentrically to the vertical axis.
- a discharge lamp is provided as the light source, which emits individual light flashes and has an essentially point-shaped unidirectional light radiation, it is necessary to generate the desired light distribution that the ring prisms extend over the entire height of the light hood.
- the ring prisms are light-collecting and not light-scattering.
- the object of the invention is that in addition to the internal cylindrical lenses for horizontal scattering, the light hood should also have optical means for vertical scattering.
- the inner cylindrical lenses should not be directly superimposed with another scattering optics and the outside of the light hood should be provided with only small, not sharp-edged and all-round depressions, so that depressions that are difficult to clean are avoided.
- the V-shaped recesses are formed by a ring prism overlaid with lenses by a concave cross section of the recesses, which run in the ring band, which corresponds in width approximately to the height of the reflective surface of the reflector. Due to the number of rings in the band and its vertically scattering lens shape, it is possible to measure exactly the light value that is required for such a luminaire in accordance with the ECE standard with possible tilting around the zero position. In addition, the structure of this ring band forms good preconditions for preventing dirt from settling or for a self-cleaning effect.
- the light hood has the shape of a semi-ellipse cut off on its long axis in the central vertical section. This shape enables optimal wind slippage even when driving at speeds above 100 km / h.
- the shape in conjunction with an elastic base guarantees low susceptibility to contact with low-hanging branches by sliding them slightly and the lamp resuming its old position.
- Another advantage of this semi-elliptical shape is not insignificant in a successful design, which is well adapted to the shape of today's bodies.
- Another advantageous feature of the embodiment of the invention shows that the concave curve of the flanks of the ring prisms forms circular sections and the two circular sections have a different radius.
- the radii of the upper leg of each V-shape are larger than the lower. Both radii also become continuously larger from bottom to top. This is largely due to the semi-elliptical shape, which requires that separate dimensions be determined for each ring prism and each leg of its V-shape in order to meet the lighting requirements for all required inclinations and observation heights by the viewer.
- the light hood (1) of the warning light according to the invention shown in FIG. 1 has the shape of an ellipse cut off on its long axis, the vertical axis (X).
- the concave flanks (4) are designed as ring prisms (8) overlaid with lenses.
- Tapered cylindrical lenses (5) are arranged in the effective reflection area of the reflector (6). With its open edge, the light hood (1) is inserted in an elastic lower part (7) on which the reflector (6) and the incandescent lamp (3) are rotatably attached.
- FIG. 3 shows the vertically scattering, concave flanks (4) for some ring prisms (8), the radii of curvature (R1, R2) continuously increasing from bottom to top in the mounting position on the light hood (1).
- R1, R2 the radii of curvature
