Abstract

The headlamp has a paraboloid primary reflector (11) with an upwardly-pointing optical axis (12), and a semi-paraboloid secondary reflector (15) situated on top, whose optical centre is identical with the outer focal point (14) of the primary reflector (11). A stop (17) forming the bright/dark boundary of the dipped beam is arranged between the focal point (14) and the apex (18) of the secondary reflector (15). Alternatively, the primary reflector (11) can be constructed in a paraboloid fashion transverse to the vehicle's longitudinal centre plane, and the secondary reflector (15) can have the form of a conical section or different conical sections or mathematically describable points or corresponding zones, so that the disc (24) covering the headlamp need not have optical media. The headlamp has a short horizontal overall depth, and a low exit aperture. <IMAGE>

Description

Die Erfindung geht aus von einem Abblendlicht-Scheinwerfer für Straßenfahrzeuge nach der Gattung des Anspruchs 1. Ein derartiger Scheinwerfer ist beispielsweise in der US-PS 1 981 328 dargestellt und beschrieben, dessen Blende zwischen dem optischen Mittelpunkt und der Lichtaustrittsöffnung des Sekundärreflektors angeordnet ist, wodurch die eine Blendung des Gegenverkehrs verursachenden Lichtstrahlen abgeschirmt werden.The invention is based on a low-beam headlamp for road vehicles according to the preamble of claim 1. Such a headlamp is shown and described, for example, in US Pat the rays of light causing glare to oncoming traffic are shielded.

Das derart erzeugte Lichtbündel erfüllt jedoch nicht die Bedingungen, die heute durch den Gesetzgeber an das Abblendlicht gestellt werden.However, the light beam generated in this way does not meet the conditions that are placed on the low beam by the legislature today.

Vorteile der ErfindungAdvantages of the invention

Mit dem Abblendlicht-Scheinwerfer für Straßenfahrzeuge nach der Erfindung wird das im vorerwähnten Stand der Technik dargelegte Problem mit einfachen technischen Mitteln gelöst. Die erfindungsgewollte Wirkung tritt immer dann ein, wenn die Kante der Blende im oder in der Nähe des optischen Mittelpunktes des Sekundärreflektors/ äußeren Brennpunkts des Primärreflektors angeordnet ist.With the low-beam headlamp for road vehicles according to the invention, the problem set out in the aforementioned prior art is solved with simple technical means. The effect desired by the invention always occurs when the edge of the diaphragm is arranged in or near the optical center of the secondary reflector / outer focus of the primary reflector.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. Mit der Ausgestaltung nach Anspruch 2 wird die Temperaturkonvektion dadurch günstig beeinflußt, daß der thermische Auftrieb die Wärme der Glühlampe in die Außenatmosphäre befördert. Mit der Ausgestaltung des Scheinwerfers nach Anspruch 3 erhält man ein besonders breit gestreutes Lichtbündel. Bei herkömmlichen Scheinwerfern erzeugt der Reflektor das sogenannte Rohlichtbündel, das durch optische Mittel insbesondere an einer Streuscheibe derart beeinflußt wird, daß das vorgeschriebene Lichtbündel entsteht. Mit der Weiterbildung nach Anspruch 4 oder 5 sind derartige optische Mittel nicht mehr erforderlich, so daß die Austrittsöffnung des Scheinwerfers lediglich durch eine optisch unwirksame, nur transparante Scheibe abzudecken ist.Advantageous developments of the invention are described in the subclaims. With the configuration according to claim 2, the temperature convection is influenced favorably in that the thermal buoyancy transports the heat of the incandescent lamp into the outside atmosphere. With the design of the headlamp according to claim 3, a particularly wide beam of light is obtained. In conventional headlights, the reflector produces the so-called raw light beam, which is influenced by optical means, in particular on a lens, in such a way that the prescribed light beam is produced. With the development according to claim 4 or 5, such optical means are no longer required, so that the outlet opening of the headlamp can only be covered by an optically ineffective, only transparent pane.

Mit der Ausgestaltung nach Anspruch 7 wird das erzeugte Lichtvolumen beachtlich vergrößert. Mit der Weiterbildung nach Anspruch 8 wird ein Weg aufgezeigt, um die den Leuchtkörper enthaltende Glühlampe in den Reflektor in günstiger Weise von dessen Rückseite einzusetzen und Lichtabschattungen der Glühlampe vermieden werden.With the embodiment according to claim 7, the light volume generated is increased considerably. With the development according to claim 8, a way is shown to insert the filament containing the filament in the reflector in a favorable manner from the rear and avoid light shading of the filament.

Mit der Weiterbildungen nach Anspruch 9 wird ein Weg gewiesen, um den Reflektoren die optischen Mittel zuzuordnen und die Herstellung des Scheinwerfers zu vereinfachen. Die Kante des Primärreflektors wird dabei soweit in den Bereich des optischen Mittelpunktes des Sekundärreflektors vorgezogen, daß sich eine Entformung der einstückigen Reflektoreinheit aus dem Herstellwerkzeug günstig bewerkstelligen läßt.With the developments according to claim 9, a way is shown to assign the optical means to the reflectors and to simplify the manufacture of the headlamp. The edge of the primary reflector is advanced so far into the area of the optical center of the secondary reflector that demolding of the one-piece reflector unit from the manufacturing tool can be accomplished inexpensively.

Der Vorteil des erfindungsgemäßen Scheinwerfers besteht u.a. in seiner geringen Bautiefe (in Längsrichtung des Fahrzeugs) und seiner niedrigen Höhe der Lichtaustrittsöffnung.The advantage of the headlamp according to the invention includes in its shallow depth (in the longitudinal direction of the vehicle) and its low height of the light exit opening.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der einzigen Figur dargestellt; diese zeigt den Vertikalschnitt durch einen Abblendlicht-Scheinwerfer für Straßenfahrzeuge in unmaßstäblicher, schematischer Darstellung.An embodiment of the invention is shown in the single figure; this shows the vertical section through a low-beam headlamp for road vehicles in a scale, schematic representation.

Beschreibung des AusführungsbeispielesDescription of the embodiment

Der Abblendlicht-Scheinwerfer für Straßenfahrzeuge hat einen ellipsoiden Primärreflektor 11, dessen optische Achse 12 senkrecht zur Fahrbahn steht und parallel zur nichtgezeichneten Längsmittelebene des Fahrzeugs angeordnet ist und den inneren Brennpunkt 13 sowie den äußeren Brennpunkt 14 das Ellipsoides enthält. Ein halbseitiges Paraboloid bildet einen Sekundärreflektor 15, dessen optischer Mittelpunkt identisch ist mit dem äußeren Brennpunkt 14 des Primärreflektors 11 und dessen optische Achse 16 annähernd rechtwinklig auf der optischen Achse 12 des Primärreflektors 11 steht.The low beam headlamp for road vehicles has an ellipsoidal primary reflector 11, the optical axis 12 of which is perpendicular to the roadway and is arranged parallel to the longitudinal longitudinal plane of the vehicle, not shown, and contains the inner focal point 13 and the outer focal point 14 which contains the ellipsoid. A half-sided paraboloid forms a secondary reflector 15, the optical center of which is identical to the outer focal point 14 of the primary reflector 11 and the optical axis 16 of which is approximately at right angles to the optical axis 12 of the primary reflector 11.

Zwischen dem optischen Mittelpunkt 14 und dem Scheitel 18 des Sekundärreflektors 15 ist eine Blende 17 angeordnet, deren optisch wirksame Kante 19 die Helldunkelgrenze des Abblendlichtbündels formt. Der Primärreflektor 11 ist unterhalb dem Sekundärreflektor 15 angeordnet, und beide sind mit der Blende 17 aus einem einzigen Stück hergestellt und bestehen aus einem Kunststoff. Der Rand 20 des Primärreflektors 11 ist weitmöglich in den Bereich des äußeren Brennpunkt 14 herangeführt, und beide Reflektoren 11, 15 sind derart zusammengefügt, daß nur reflektierte Strahlen aus dem Scheinwerfer austreten. Im lichttechnisch unwirksamen Bereich des Primärreflektors 11 und unterhalb der Blende 17 ist eine Öffnung 21 angeordnet für den Zugang zur nicht gezeichneten Glühlampe, deren Leuchtkörper 9 annähernd im inneren Brennpunkt 13 angeordnet ist.Between the optical center 14 and the apex 18 of the secondary reflector 15, an aperture 17 is arranged, the optically effective edge 19 of which forms the light-dark boundary of the low beam. The primary reflector 11 is arranged below the secondary reflector 15, and both are made with the diaphragm 17 from a single piece and consist of a plastic. The edge 20 of the primary reflector 11 is brought as far as possible into the area of the outer focal point 14, and both reflectors 11, 15 are joined together in such a way that only reflected rays emerge from the headlight. In the area of the primary reflector 11, which is ineffective in terms of lighting technology, and below the diaphragm 17, an opening 21 is arranged for access to the incandescent lamp, not shown, the lamp body 9 of which is arranged approximately in the inner focal point 13.

Folgende Alternativen zum Vorbeschriebenen sind möglich: Der Primärreflektor 15 ist in einer Ebene, die quer zur Fahrzeuglängsmittelebene liegt, parabolisch ausgebildet. Der Sekundärreflektor 15 hat die Form eines Kegelschnittes oder setzt sich aus unterschiedlichen Kegelschnitten zusammen.The following alternatives to the above are possible: The primary reflector 15 is parabolic in a plane that lies transversely to the vehicle longitudinal center plane. The secondary reflector 15 has the shape of a conic section or is composed of different conical sections.

Der Sekundärreflektor 15 besteht aus mathematisch beschreibbaren Punkten oder aus entsprechenden Zonen:

  • Ein Gehäuse 22 mit einer Kappe 23 auf der Höhe der Öffnung 21 nimmt die Einheit der Reflektoren 11, 15 und eine Scheibe 24 auf und ist in nicht näher dargestellter Weise in der Karosserie 25 des Fahrzeugs befestigt. Die Scheibe 24 hat bei der erstbeschriebenen Ausführung der Reflektoren optische wirksame Mittel (nicht gezeichnet), jedoch bei den Alternativen der Reflektoren 11, 15 sind keine derartigen Mittel notwendig, so daß die Scheibe nur die Funktion des Verschließens der Austrittsöffnung des Gehäuses 22 erfüllt.
The secondary reflector 15 consists of mathematically describable points or corresponding zones:
  • A housing 22 with a cap 23 at the level of the opening 21 accommodates the unit of the reflectors 11, 15 and a disk 24 and is fastened in the body 25 of the vehicle in a manner not shown. The disc 24 has the first described execution of the Re optically effective means (not shown), but with the alternatives of the reflectors 11, 15 no such means are necessary, so that the pane only fulfills the function of closing the outlet opening of the housing 22.
