Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reflector-1 incandescent lamp, a cover plate, and a direction of the light beam reflected by the reflecting surface. starting from a signal light, in particular a direction indicator light for a motor vehicle, with a color filter having a raster of , and a reflective layer arranged in front of this color filter and having perforations for the unhindered passage of the partial luminous flux. do. A signal light of this type is known from West Patent Publication No. 2939329.

In order to obtain the embodiment illustrated in FIG. 5 of this patent publication, it is possible that during the production of the reflective layer, i.e. during the vapor deposition of aluminum on the color filter, the bottom of the perforation, which is configured as a closed-ended hole, is It turns out that aluminum does not necessarily remain absent. As a result, the free passage of the partial beams is obstructed, which impairs the intensity of the signal light.

The problems discussed in this state of the art are generally solved by simple means with the signal light according to the invention. A special advantage is
When depositing aluminum on one side of the plate, it is trivial whether the aluminum coats or does not coat the walls of the perforations, which makes the manufacturing process easy to represent and practically free of waste. It is recognized that

Other preferred embodiments of the invention are described in the dependent claims. The feature of the signal light according to claim 2 makes it possible to match the color of the switched-off signal light and the vehicle body. The features of the signal light according to claim 4 result in a reduced cross-sectional depth of the signal light.

If the signal light is constructed according to claim 5 and in particular claim 6, the color of the reflective layer can still be clearly recognized from different flashing directions by passers-by and cars. Wear. A further configuration of the signal light according to claim 7 allows the plates and color filters to be fully adapted to the properties of the cover plate.

An embodiment of the invention is illustrated in the drawings and will be described in detail below.

Figure 1 shows a partially reflecting surface 11 from an automobile direction indicator light.
An incandescent lamp 12 is shown having a reflector 10 having a reflector 10 and an incandescent coil 13, the center of gravity of which is at the focal point of the reflector 10.

A colorless cover plate 14 with optical means 15 formed on its inner surface for the formation of light emerging from the direction indicator light closes the light exit opening of the reflector 10.

In front of the incandescent lamp 12, that is, in the direction of the light beam reflected by the reflective surface 11, a color filter 16 is arranged, and the surface of this color filter facing the incandescent lamp 12 forms a convergence filter having a hexagonal shape. The lens 17 is integrally formed. This color filter 16 produces a desired signal color by the light flux passing through it.

In front of the color filter 16, a plate 18 with perforations 19 is arranged, all perforations having the shape of a truncated cone with a cross section that decreases in the direction of light passage. Due to the surface of the plate 18 facing the cover plate 14, the spherical lenses 21 likewise protrude in a hexagonal manner in a raster pattern. An aluminum covering is provided on the spherical lens 21, which acts as a reflective layer 11. A spherical lens 21 is mounted on one of the all converging lenses 17 in such a way that the axis 20 coincides with the axes of the converging lens 17, the spherical lens 21 and the borehole 19.

The configuration of the flashing light will be explained for four light rays 23: the light ray 23 emitted from the incandescent coil 13 is reflected by the reflective surface 11 generally parallel to the optical axis 24 of the direction indicator light;
The total light [23] then passes through a color filter 16, in which case the light beam receives a signal color, and a partial beam is formed which is converged by the total converging lens 17, which partial beam is unobstructed. passes through the associated perforation 19 in the plate 18. In this case, the cone of light flux is approximately equal to perforation 1
It corresponds to the conical shape of 9. Thereafter, the partial light beams diverge and are adjusted by means of their optical means 15 during passage through the cover plate 14 in such a way that the above-mentioned flashing light still occurs.

The different light entering the direction indicator light from the outside, symbolized by three rays 25't%, is reflected by the reflective layer 22. As a result, the color of the covering plate 14 having the reflective layer 21 appears to passersby and cars.

FIG. 2 shows a diverging plate 3 with formed optical means 35.
4 is a partial view of a direction indicator light that retracts vertically from bottom to top. Similarly, there are 26 color filters in total.
and plate 28 is retracted. For this purpose, the converging lens 27 with its associated part, the spherical lens 211 with its associated part and the reflective layer 22 are likewise recessed in the vertical direction from bottom to top in the form of a trapezoid.
