Abstract

Scheinwerfer zur dynamischen Modellierung der Lichtmenge zum gleichzeitigen Ausleuchten verschiedener Bereiche mit verschiedenen Helligkeitsstufen, dadurch gekennzeichnet, dass, der Scheinwerfer mit einer Polarisationsmatrix (3) versehen ist, der die Umgebung des auszleuchtenden Bereiches in Graustufen nachzeichnet.Headlight for dynamic modeling of the amount of light for simultaneous illumination of different areas with different levels of brightness, characterized in that the headlight is provided with a polarization matrix (3) which traces the surroundings of the area to be illuminated in gray levels.

Description

Scheinwerfer sind heutzutage starr in ihrer Lichtausschüttung angeordnet. Das bedeutet, dass in allen Bereichen die gleiche Menge an Licht ausgesendet wird.Headlamps are nowadays rigidly arranged in their light distribution. This means that the same amount of light is emitted in all areas.

Zur Anpassung an verschiedene Lichtverhältnisse werden unterschiedliche Wattleistungen der Lampen benutzt. So unterscheidet man zwischen Stand-, Abblend- und Fernlicht. Zusätzlich werden extra Leuchten für das Nebel- und Kurvenlicht verwendet, die bei Bedarf eingeschaltet werden. Dabei handelt es sich aber immer um statische Lichtmengen die abgestrahlt werden.To adapt to different lighting conditions different wattages of the lamps are used. So you can differentiate between Steady, dipped and high beam. In addition, extra lights for the fog and cornering lights are used, which are switched on when needed. However, these are always static amounts of light that are emitted.

Ein dynamisches Modellieren des Lichtbildes, dass gleichzeitig verschiedene Bereiche mit verschiedenen Helligkeitsstufen ausleuchtet, entsprechend der Umgebungsgestaltung und Sichtverhältnisse, ist aber nicht möglich.A dynamic modeling of the light image that simultaneously illuminates different areas with different brightness levels, according to the environment design and visibility, but is not possible.

Der in Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, mit einer Lampe gleichzeitig verschiedene Bereiche der Landschaft mit unterschiedlicher Helligkeit auszuleuchten.The specified in protection claim 1 invention is based on the problem with a lamp simultaneously illuminate different areas of the landscape with different brightness.

Mit Schutzanspruch 1 wird das oben genannte Problem gelöst.With protection claim 1, the above problem is solved.

Mit der Erfindung wird erreicht, dass gleichzeitig Schilder hell ausgeleuchtet, Umgebung und Straßenverlauf mit ausreichend Licht beleuchtet und Passanten und Gegenverkehr wenig angestrahlt werden um ein Blenden zu verhindern. Die Gesammtlichtmenge kann entsprechend den jeweiligen Gegebenheiten wie Nebel, Regenmenge oder klarer Sicht angepasst werden.With the invention it is achieved that at the same time signs brightly lit, illuminated environment and road with sufficient light and passersby and oncoming traffic are little illuminated to prevent glare. The total amount of light can be adjusted according to the respective conditions such as fog, rainfall or clear view.

Die Umsetzung der Modellierung besteht in einer graphischen Polarisationsfolie, die ähnlich wie die Ziffern auf einem Taschenrechner die Umgebung in Graustufen auf dem Scheinwerfer abbildet. So werden relevante Elemente wie z. B. Schilder oder die unmittelbare Fahrbahn kontrastarm ausgeleuchtet, aber der Gegenverkehr mit mehr Kontrast versehen.The implementation of the modeling consists in a graphic polarizing film, which, like the figures on a calculator, images the environment in grayscale on the spotlight. Thus, relevant elements such. B. signs or the immediate road lit with low contrast, but the oncoming traffic provided with more contrast.

Durch ein umgebungserfassendes Verfahren, wie z b. stereoskopische Kameras zur Bilderfassung oder Radarabtastung oder Ähnliches, wird die Landschaft erfasst. Eine Analyse des Bildes teilt vorhandene Objekte in die verschiedenen Helligkeitsstufen ein Schilder, oder der Fahrbahnverlauf bekommen eine sehr hohe Ausleuchtung, die nahe Umgebung eine Ausreichende und Gegenverkehr eine geringe Ausleuchtung um ein Blenden zu verhindern.By an environment-aware method, such as. stereoscopic cameras for image capture or radar scanning or the like, the landscape is captured. An analysis of the image divides existing objects into the different levels of brightness Signs, or the course of the road get a very high level of illumination, the near surroundings a sufficient and oncoming traffic a low illumination to prevent dazzling.

Auf der Basis dieser Berechnungen wird eine Ausleuchtungsmatrix auf der Polarisationsfolie an der Scheibe des Scheinwerfers gezeichnet. Diese wird durch kontinuierliche Aktualisierung des Umgebungsbildes bei der Fahrt synchron zur Umgebung gehalten.Based on these calculations, an illumination matrix is drawn on the polarizing film on the headlamp lens. This is kept synchronous with the environment by continuously updating the environment image while driving.
