Abstract

The mask for a motor vehicle headlight is positioned between the light source with reflector and the lens. The mask is of light impermeable material and, through application of an electrical voltage at a fixed position, allows light passage to alter the passage of the light rays.

Description

Zur Veränderung des Strahlmusters eines Linsenmotorradscheinwerfers, Projektionsmotorradscheinwerfers, Polyellipsoidscheinwerfers oder des Scheinwerfers eines ähnlichen Einspurfahrzeuges eignet sich diese Blende. Aus einem Sensor oder einer Elektronik für die Schräglagenerfassung, eines Rollwinkelsensors, eines Nickwinckelsensors oder anderer Lagesensoren, welche Daten erfassen, die für die Strahlmustersteuerung geeignet sind, und manuelle Schaltungen für Aufblenden, für Ladungsausgleich und andere, werden die Daten in einer Elektronischen Schaltung in ein geeignete Strahlmuster umgerechnet und damit die Öffnungen in der Blende oder in den hintereinander angeordneten Blenden angesteuert. To change the beam pattern of a lens motorcycle headlight, projection motorcycle headlight, This aperture is suitable for polyellipsoid headlights or the headlights of a similar single-track vehicle. From a sensor or electronics for the inclination detection, a roll angle sensor, one Nickwinckelsensors or other position sensors, which collect data for the beam pattern control are suitable, and manual circuits for fading, for charge balancing and others, the data in an electronic circuit converted into a suitable beam pattern and thus the openings in the Aperture or controlled in the panels arranged one behind the other.

Das Prinzip ähnelt der Hintergrundbeleuchtung einer LCD-Anzeige eines Taschenrechners oder eines ähnlichen Instrumentes. Die dunklen Stellen verhindern einen Lichtdurchgang und steuern so das Strahlmuster. The principle is similar to the backlight of an LCD display on a calculator or the like Instrument. The dark areas prevent the passage of light and thus control the beam pattern.

Fig. 1 zeigt die Anordnung der Blende innerhalb des Scheinwerfers, Fig. 1 shows the arrangement of the aperture in the headlight,

Fig. 2 zeigt die Anordnung der Blende innerhalb des Scheinwerfers. Fig. 2 shows the arrangement of the aperture within the headlamp.

Die sich verdunkelnden Stellen werden bei der Herstellung der Blende festgelegt. Dies kann in einer Matrix erfolgen mit kleinen Abdunkelstellen oder sektorhaft oder linienhaft, oder eine Kombination dieser Anordnungen. The places that darken are determined during the manufacture of the panel. This can be done in a matrix take place with small darkening points or sector-like or linear, or a combination of these arrangements.

Es richtet sich je nach der Anforderung der Strahlmustersteuerung. It depends on the requirements of the beam pattern control.

Es können auch mehrere Blenden hintereinander verwendet werden, um verschiedenen Strahlmusteranforderungen zu kombinieren. It is also possible to use several diaphragms in succession to different Combine beam pattern requirements.

Vorteilhaft ist die elektrisch schnelle Veränderung des Strahlmusters, da keine mechanischen Teile bewegt werden müssen. Insbesondere für Leuchtweitenregulierung oder Strahlmusterausgleiche bei Kurvenfahrt oder Auf- und Abblendlichtwechsel. The rapid electrical change of the beam pattern is advantageous because no mechanical parts move Need to become. Especially for headlight range adjustment or beam pattern compensation when cornering or Change of low and high beam.

Stand der TechnikState of the art

Blenden nur aus Blech oder motorisch drehbar, oder manuell mechanisch oder elektromotorisch veränderbar. Apertures made only from sheet metal or rotatable by motor, or manually changeable mechanically or by electric motor.

Zugrundeliegendes ProblemUnderlying problem

Schnelle und massenträgheitsfreie Veränderung des Strahlmusters. Fast and inertia-free change of the beam pattern.

Wege zum Ausführen der ErfindungWays of Carrying Out the Invention

Zur Verwendung bei Motorradscheinwerfern. For use with motorcycle headlights.

Blende aus Glas oder Kunststoff mit einer elektrisch in der Lichtdurchlässigkeit veränderbaren Schicht, welche genügend lichtundurchlässig wird, um die Lichtstrahlen der Lichtquelle abzudunkeln. A cover made of glass or plastic with a layer that can be electrically changed in terms of light transmission becomes sufficiently opaque to darken the light rays from the light source.
