Description

Beleuchtungslinse für Signallaternen und Scheinwerfer In der Patentschrift 52q.705 ist eine Beleuchtungslinse für Signallampen von hohem Wirkungsgrad beschrieben. Die vorliegende Erfindung betrifft eine weitere Ausgestaltung dieser Beleuchtungslinse zur Erhöhung des Wirkungsgrades.Illumination lens for signal lanterns and headlights In the patent 52q.705 describes a lighting lens for signal lamps of high efficiency. The present invention relates to a further embodiment of this lighting lens to increase the efficiency.

In dem Hauptpatent ist eine Ausführungsform erwähnt, die einem seitwärts stehenden Beobachter gestattet, zu erkennen, ob die Lampe hinter der Beleuchtungslinse brennt. Zu diesem Zweck soll die vordere Linsenoberfläche stellenweise so deformiert werden, daß die hindurchgehenden Beleuchtungsstrahlen eine von der achsenparallelen Richtung stark abweichende Richtung erhalten.In the main patent an embodiment is mentioned that one sideways standing observer allowed to see whether the lamp is behind the lighting lens burns. For this purpose, the front lens surface should be deformed in places that the illuminating rays passing through are one of the axially parallel Direction received strongly deviating direction.

Zweckmäßig kann man nun gemäß der vorliegenden Erfindung die Anordnung so treffen, daß man in die gewölbte Linsenoberfläche eine oder mehrere Riefen einschleift, die am besten koaxial angeordnet sind, wie dies in Abb. i und 2 dargestellt ist; Abb. i zeigt die Ausführungsform mit einer einzigen Hohlkehle h, Abb. 2 eine solche mit mehreren Hohlkehlen (Riefen) r. Im allgemeinen wird bei einer derartigen Ausführung ein Teil des sonst für die achsenparallele Beleuchtung verwendeten Lichtes verlorengehen. Will man das vermeiden, dann verlegt man zweckmäßig diese Streuriefen in jene Teile der Linsenoberfläche, wo infolge der eintretenden Totalreflexion achsenparallele Strahlen nicht mehr austreten würden, d. h. also, man verlegt die Riefen in jene äußersten Randteile der Linsenoberfläche, die für die achsenparallele Beleuchtung nicht mehrausgenutzt werden können.Appropriately you can now according to the present invention, the arrangement hit in such a way that one or more grooves are grinded into the curved surface of the lens, which are best placed coaxially, as shown in Figures i and 2; Fig. I shows the embodiment with a single fillet h, Fig. 2 such with several fillets (grooves) r. In general, in such an implementation some of the light that is otherwise used for the axis-parallel lighting is lost. If you want to avoid that, then it is appropriate to relocate these scatter marks to those parts the lens surface, where the axis is parallel to the total internal reflection Rays would no longer emerge, d. H. so, one relocates the grooves in those outermost edge parts of the lens surface, which are for the axially parallel illumination can no longer be used.
