Der Erfindung liegt die Aufgabe zugrunde, die Lichtausbeute bei einem Fahrzeugscheinwerfer bei gleichzeitiger Erzeugung eines scharf umrissenen Lichtbildes zu erhöhen.Of the Invention is based on the object, the luminous efficacy at a Vehicle headlights while generating a sharp outlined To increase the light picture.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Anspruchs 1.The Solution of this problem is inventively with the features of claim 1.
Gemäß der Erfindung ist bei einem Fahrzeugscheinwerfer mit einem Leuchtmittel, einem das Leuchtmittel teilweise umgebenden, eine Hauptabstrahlrichtung aufweisenden Hauptreflektor, einer Zusatzreflektoranordnung und einer Lichtscheibe vorgesehen, dass der Hauptreflektor in einem Zentralbereich eine Lichtdurchtrittsöffnung aufweist, wobei das durch die Lichtdurchtrittsöffnung durchtretende Licht mittels der Zusatzreflektoranordnung im Wesentlichen in die Hauptabstrahlrichtung des Hauptreflektors umgeleitet wird. Gemäß der Erfindung wird also das Licht, das beim Stand der Technik auf den Zentralbereich fällt, von dort auf das Leuchtmittel reflektiert und von diesem abgeschirmt oder zumindest undefiniert gestreut wird, genutzt, um eine definierte Beleuchtung zu erhalten. Auf diese Weise wird die Lichtausbeute bei gleichzeitiger Erzeugung eines scharf umrissenen Lichtbildes erhöht, denn die die Schärfe des Lichtbildes beeinflussenden Elemente eines bekannten, optimierten Scheinwerfers können und werden unverändert beibehalten.According to the Invention is in a vehicle headlamp with a light source, a partially surrounding the lamp, a main emission direction comprising main reflector, an auxiliary reflector arrangement and a lens provided that the main reflector in one Central region has a light passage opening, wherein the passing light through the light passage opening the additional reflector arrangement substantially in the main emission direction the main reflector is redirected. According to the Invention is therefore the light that in the prior art on the central area falls from there to the bulb and reflected by this is shielded or at least undefined scattered, used, to get a defined lighting. This way will the luminous efficacy while generating a sharply outlined Photograph increases, because the sharpness of the photograph influencing elements of a known, optimized headlamp can and will remain unchanged.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass der Hauptreflektor zur Erzeugung des Lichtbildes eines Abblend- oder Nebellichtes ausgebildet ist.According to one preferred embodiment of the invention it is provided that the Main reflector for generating the light image of a Abblend- or Fog light is formed.
Gemäß einer weiter bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Zusatzreflektoranordnung zur Beleuchtung eines Nahbereiches ausgebildet ist, der von einer Hell-Dunkelgrenze des Abblend- bzw. Nebellichtes beabstandet ist. Auf diese Weise ist der technische Aufwand zur Berechnung und Auslegung eines erfindungsgemäßen Scheinwerfers äußerst gering.According to one further preferred embodiment of the invention, it is provided that the additional reflector arrangement for illuminating a Nahbereiches is formed, the of a bright-dark border of the dimming or Fog light is spaced. In this way, the technical Expenditure for calculating and designing a headlamp invention extremely low.
Gemäß einer weiter bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass der Hauptreflektor im Wesentlichen kalottenförmig, insbesondere im Wesentlichen kugelsegmentförmig, rotationsparabolidförmig oder rotationshyperbolidförmig ausgebildet ist. Eine solche Ausgestaltung hat sich zur Lichtbündelung als besonders vorteilhaft erwiesen.According to one further preferred embodiment of the invention, it is provided that the main reflector substantially dome-shaped, in particular in Essentially spherical segment-shaped, rotationsparabolidförmig or Rotationshyperbolidform is formed. Such Design has to light bundling as special proved advantageous.
Gemäß einer weiter bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Zusatzreflektoranordnung zwei im Wesentlichen eben ausgebildete Reflektorflächen aufweist.According to one further preferred embodiment of the invention, it is provided that the additional reflector assembly two substantially planar Reflector surfaces has.
Gemäß einer weiter bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Zusatzreflektoranordnung zwei Reflektorflächen aufweist, die im Wesentlichen kalottenförmig, insbesondere im Wesentlichen kugelsegmentförmig, rotationsparabolidförmig oder rotationshyperbolidförmig ausgebildet sind.According to one further preferred embodiment of the invention, it is provided that the additional reflector arrangement has two reflector surfaces which essentially dome-shaped, in particular substantially spherical segment, rotationsparabolidförmig or Rotationshyperbolidförmig are formed.
Gemäß einer weiter bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass an den Leuchtmitteln eine Blende ausgebildet oder angeordnet ist.According to one further preferred embodiment of the invention, it is provided that on the bulbs a diaphragm is formed or arranged.
Gemäß einer weiter bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass im Bereich des Leuchtmittels ein optisches Element, insbesondere eine Linse angeordnet ist.According to a further preferred Ausgestal tion of the invention it is provided that in the region of the illuminant, an optical element, in particular a lens is arranged.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung im Zusammenhang mit den Zeichnungen.Further yield advantageous embodiments and refinements of the invention from the subclaims as well as from the description in connection with the drawings.
