Definitions
- the invention relates to a headlight for motor vehicles according to the preamble of claim 1.
- Such a headlight is known from DE-OS 35 19 611.
- This headlight has a reflector in which a gas discharge lamp is used as the light source.
- the light outlet opening of the headlight is covered with a lens.
- the gas discharge lamp also emits light in the UV wavelength range with high intensity.
- this UV light is harmful to health and, on the other hand, can destroy plastics and glass.
- the heat radiation of the gas discharge lamp is substantially lower than that of an incandescent lamp, so that moisture which has penetrated into the headlight or is deposited on the lens does not dry out and moisture which has frozen on the lens does not thaw. Under certain circumstances, the light emitted by the gas discharge lamp also has too high a blue component.
- the headlamp according to the invention with the characterizing features of claim 1 has the advantage over that the filter emits the light emitted by the gas discharge lamp in the UV wavelength range and therefore no UV radiation with harmful intensity can emerge from the headlamp.
- the lens By designing the lens as a UV filter, which is characterized in claim 3, a targeted heating of the lens is achieved, so that when the gas discharge lamp is operated, moisture which has deposited on the lens dries and thaws on the frozen moisture.
- the development according to claim 9 ensures that no UV radiation emerges from the headlight even when the UV filter is damaged. Due to the configuration according to claim 10, the line is interrupted when, for example, as a result of an impact, the lens moves out of the holder and thus the failure of the lens is displayed in a simple manner.
- Claim 13 ensures that the gas discharge lamp cannot be operated even if the UV filter is damaged by short-circuiting the signal lines.
- FIG. 1 shows a first exemplary embodiment of a headlamp in longitudinal section in a greatly simplified illustration
- FIG. 2 shows a second exemplary embodiment of a headlamp in longitudinal section
- FIG. 3 shows a third exemplary embodiment of a headlamp in longitudinal section
- FIG. 4 shows a detail in FIG Presentation. Description of the embodiments
- a low-beam headlight for motor vehicles shown in FIG. 1 this has a reflector 8, into which a gas discharge lamp 11 is inserted from the rear.
- the reflector 8 can, for example, have the shape of a paraboloid of revolution, but can also be divided into several different segments and is arranged in a housing 9 made of plastic.
- the light exit opening of the headlight is closed with a lens 18, which is designed as a lens.
- the gas discharge lamp 11 is supplied with the high voltage required for its operation by an ignition device 20, which is fed by the electrical system of the motor vehicle and is controlled by a control device 19.
- the gas discharge lamp 11 also emits light in the UV wavelength range with high intensity during its operation.
- the lens 18 is provided on its inside facing the reflector with a coating 23 which at least partially absorbs light in the UV wavelength range.
- the coating 23 can be formed by a thin metal layer, for example made of gold or chrome. However, the coating 23 can also be formed by a fluoride layer.
- the coating 23 can, for example, be vapor-deposited or sprayed onto the lens 18. In addition, the coating 23 not only shields the UV radiation, it also represents a coating of the glass optics shown in the lens 18, so that undesired scattering of the light rays passing through is reduced.
- the coating 23 heats up due to the absorbed UV radiation, which leads to a heating of the lens 18. Heating of the lens 18 to accelerate the drying and defrosting of the lens without the use of external energy is thus achieved.
- the lens 18 can also be used even by appropriate selection of the glass material or by appropriate additions to the glass material have the property of absorbing UV light. A brownish coloring of the coating 23 or the lens 18 can give the light emerging from the headlight a coloring so that it has a 'warmer' effect.
- the coating 23 or the lens 18 can be designed so that blue light is partially absorbed so that the light emerging from the headlight appears less blue.
- the coloring of the coating 23 or the lens 18 likewise heats the lens 18 during operation of the gas discharge lamp 11.
- a disk-shaped filter 22 shown in dashed lines in FIG. 1, is arranged between the gas discharge lamp 11 and the lens 18, and has a coating which absorbs UV light as described above for the lens 23 is provided or by appropriate choice of materials or admixtures to a glass material has the property of absorbing UV light.
- this has a reflector 10, into which a gas discharge lamp 11 is inserted from the rear. Ellipses result in the vertical and horizontal meridian section of the reflector 10, the axial arc 12 of the gas discharge lamp 11 being arranged in the region of the inner focal point Fe of the ellipses on the optical axis 13 of the reflector. In the direction of the light beams reflected by the reflector 10, an aperture 14 with an optically effective upper edge 15 is arranged below the optical axis 13 in the area of the outer focus Fe 'of the ellipses.
- the light exit direction there are also a lens 17 and a light exit opening of the headlight covering lens 18 is arranged, which can be designed as a lens.
- the light beams form the upper edge 15 of the diaphragm 14 via the objective 17 as a light-dark boundary of the light distribution of the headlight.
- the objective 17 serves as a UV filter and is provided with a coating 23 which absorbs UV light.
- the coating 23 can be designed as described in the first embodiment.
- the lens 17 can also be given UV-light-absorbing properties by a suitable glass material or by admixtures to the glass material.
- a disk-shaped UV filter 22 can be arranged between the gas discharge lamp 11 and the lens 18, or the lens 18 can serve as a UV filter by means of a coating 23 or a suitable glass material.
- FIGS. 3 and 4 show a third exemplary embodiment of the headlight, in which, as in the second exemplary embodiment, the objective 17 serves as a UV filter and has the property of absorbing UV light through a coating or a suitable glass material or additions to the glass material .
- the gas discharge lamp 11 is inserted into the reflector 10 via a lamp holder 26 and covered on its rear side with a cap 27.
- a support 28 is connected to the front edge of the reflector 10 and extends in the direction of light exit and has a holder 29 at its end facing away from the reflector 10 for receiving the objective 17.
- the carrier 28 is designed as a hollow cylinder closed on its circumference and consists of sheet metal.
- the reflector 10 forms a tight connection with the carrier 28 and the objective 17, so that neither through these parts nor between them UV radiation can escape.
- a frame 31 is arranged toward the lens 18 and has an opening 32 the size of the objective 17 for the passage of light.
- the lens 17 can be inserted into the carrier 28 from its end facing the reflector 10 and comes to rest against a radially inwardly facing edge 33 of the carrier 28 forming part of the holder 29, against which it is held by a spring ring 30 becomes.
- the spring ring 30 is open in its lower area.
- a stop 36 which here is a rivet, between which and the edge 33 the edge of the objective 17 and the spring ring 30 come to lie when the objective is assembled.
- a ceramic plate 34 preferably diametrically opposite, can be fastened to the carrier 28, which projects radially inward through the open area of the spring ring 30 when the lens 17 is mounted and overlaps the edge of the lens 17 to the side of the reflector 10.
- the ceramic plate 34 could also serve to fix the position of the lens 17 at this point if the spring ring 30 is dispensed with.
- An electrical conductor track 37 is vapor-deposited on the ceramic plate 34 and is connected via signal lines 38 to the electrical control device 19 which controls the ignition device 20.
- the ceramic plate 34 has a predetermined breaking point determined by a notch 39, the conductor track 37 on the ceramic plate 34 extending beyond the notch 39.
- the notch 39 is arranged in such a way that when a force of a certain size acts on the lens 17 in the direction of the reflector 10, the ceramic plate 34 is broken by the lens 17 moving as a result of the counter-holder 36 in its lower region from the holder 29, thereby the conductor track 37 is interrupted.
- the ceramic plate 34 can be arranged at a small distance from the lens so that it does not vibrate during operation Exposed to the lens, which could lead to an unwanted break. An interruption of the conductor track 37 is recognized by a safety circuit of the control device 19 and the operation of the gas discharge lamp 11 is prevented. This ensures that if the lens 17 is damaged as a result of an accident, for example, no UV radiation emerges from the headlight and no parts under high voltage can be touched. However, if only the lens 18 is destroyed and the lens 17 is still in its holder 29, the headlight can continue to be operated since the combination of the parts reflector, support and lens is still intact and no harmful UV radiation can escape.
- the frame 28, the ceramic plate 34 and their electrical connections are covered by the frame 31.
- a voltage divider circuit can be applied to the ceramic plate 34, which has two resistors R1 and R2, at which a defined voltage drop occurs.
- One of the lines of the voltage divider is interrupted by the predetermined break, so that the voltage drop in relation to the other branch of the voltage divider circuit changes significantly and the fault is thus indicated. If a voltage drop that deviates from the predetermined voltage drop occurs, this is recognized by the safety circuit of the control device 19 and the operation of the gas discharge lamp 11 is prevented. It is thus excluded that, for example, by short-circuiting the signal lines 38, the gas discharge lamp 11 can also be operated when the lens 17 is damaged.
