Description

Autoscheinwerfdi;-Äutobahnleuchte Es wurde bereits vorgeschlagen, bei Autoscheinwerfern, Autobahnleuehten, Rollfeldleuchten :o. dgl. einen scharf begrenzten Lichtkegel dadurch zu erzeugen, daß in unmittelbarer Nähe der Lichtquelle 3 ein System von Kondensorlinsen q möglichst kurzer Brennweite angeordnet ist, daß durch eine Scheinwerferlinse mit verhältnismäßig großer Brennweite auf der zu beleuchtenden Fläche abgebildet wird. Es hat sich insbesondere als besonders vorteilhaft erwiesen, die erwähnten Kondensorlinseri mit kurzer Brennweite kreisförmig toder halbkreisförmig um die Lichtquelle anzuordnen und die von den einzelnen Kondensorlvisen ausgehenden divergierenden Lichtbündel durch Spiegeloder Prismen a so umzulenken, daß sie auf die Scheinwerferlinse fallen. Durch Überlagerung zweier durch eine derartige Einrichtung erzeugter, aus Hell- und Dunkelzonen bestehender Lichtkegel soll ein-, lückenlose und gleichmäßige Beleuchtung :erzielt werden. Damit dies möglich ist, müssen die Breiten der einzelnen Lichtbündel und der Zwischenräume genau gleich sein. Die Überlagerung zweier Bilder wird dadurch erzeugt, daß die Sch einwerferlixise aus- zwei Teilen besteht, deren Mittelpunkte einen gewissen Abstand haben.Autoscheinwerfdi; - Motorway light It has already been suggested for car headlights, motorway lights, runway lights: o. like. a sharp to generate limited light cone that in the immediate vicinity of the light source 3 a system of condenser lenses q is arranged as short a focal length as possible that through a headlight lens with a relatively large focal length on the one to be illuminated Area is mapped. In particular, it has proven to be particularly advantageous the aforementioned condenser lenses with a short focal length are circular or semicircular to arrange the light source and those emanating from the individual condenser vises to deflect diverging light bundles by mirrors or prisms a so that they on the headlight lens fall. By superimposing two by such a device The cone of light produced, consisting of light and dark zones, should be one, seamless and uniform lighting: to be achieved. For this to be possible, the Widths of the individual light bundles and the spaces between them must be exactly the same. The overlay two images is produced by the fact that the headlamp lixise is made up of two parts exists, the centers of which have a certain distance.

Um ein glattes Aneinanderschließ-,n der Bilder der Kondensorlinsen zu @erzielen, wird gemäß der Erfindung eine Blende 7, deren Öffnungen und Zwischenräume gleiche Breite haben, in der Brennebene der nicht gezeichneten Scheinwerferlinse angeordnet und diese Scheinwerferlinse aüs zwei Segmenten zusamm,engesetzt, deren Mittelpunkte parallel, zur Verbindungslinie der Mitten der Blendenöffnungen um die Breite einer Blendenöffirung bzw. die gleiche Brite der Zwischenräume auseinandergerückt sind.To ensure a smooth interconnection, n the images of the condenser lenses to @ achieve, according to the invention, a diaphragm 7, its openings and spaces have the same width in the focal plane of the headlight lens, not shown arranged and this headlight lens composed of two segments, their Center points parallel to the line connecting the centers of the aperture openings around the Width of a diaphragm opening or the same width of the spaces moved apart are.
