Description

Lampenglas für Kopflampen von Fahrzeugen u. dgl. Gegenstand der Erfindung ist ein Lampenglas für Kopflampen von Fahrzeugen u. dgl. Das Glas hat an der Spitze einen farbigem, vorzugsweise blauen oder grünen Filterbelag und am Boden einen Spiegelbelag. Die beiden Beläge sollen verhindern, daß hlendendes Licht nach vorn austritt. Die Erfahrung zeigt aber, daß sie dazu nicht imstande sind; denn sie können Strahlen, die vom Leuchtkörper nach rückwärts auf den ge$ektol9 fallen, weder abfangen noch- ablenken, so daß die Lampe trotz der getroffenen Vorkehrungen blendet.Lamp glass for head lamps of vehicles and the like. The subject of the invention is a lamp glass for head lamps of vehicles and the like a colored, preferably blue or green filter pad and a mirror pad on the floor. The two coverings are intended to prevent glare from escaping to the front. the But experience shows that they are incapable of doing this; because they can shine which fall backwards from the luminous body onto the ge $ ektol9, neither intercept nor- deflect so that the lamp dazzles in spite of the precautions taken.

Nach der Erfindung werden diese falschen Strahlen durch einen zweiten, farbigen Filterbelag abgefangen, der auf dem unbedeckten Teil des Lampenglases angebracht ist und von rückwärts nach vom in seiner Farbendichte abnimmt.According to the invention, these will be wrong Rays caught by a second, colored filter pad on the uncovered part of the lamp glass is attached and from back to front in its color density decreases.

Auf der Zeichnung ist als Ausführungsbeispiel eine nach der Erfindung belegte Glühlampenbirne dargestellt, und zwar in Abb. i in Stirnansicht, Abb. a in Seiten-ansicht und Abb. 3 im Grundriß.In the drawing, an area occupied by the incandescent bulb invention is as an embodiment shown, namely in Fig. I in end view, fig. In a side view and to the Fig. 3 in plan.

Der Teil der Birne, den die vom Glühfaden 1 nach unten gebenden Strahlen treffen" ist mit einem Spiegel z belegt, der nach außen mit einer undurchsichtigen Schicht abgedeckt ist. Der Spiegel kann innen und außen angebracht sein. Vorzugsweise wird er so bemessen, daß er nicht die ganze untere Hälfte der Birne abdeckt, sondern die in Abb, 3 erkennbare wappenschildartige Form hat.The part of the bulb that the rays emitting from the filament 1 downwards meet "is covered with a mirror z, which is opaque to the outside Layer is covered. The mirror can be attached inside and outside. Preferably it is dimensioned so that it does not cover the entire lower half of the pear, but has the escutcheon-like shape that can be seen in Fig. 3.

Um die blendenden Strahlen abzufangen, wird die Birne vorn mit einem dicken Belag 3 aus Farbstoff versehen, der den Glühfaden nach vorn völlig abdeckt. Der Belag wird blau oder grün gemacht, damit er möglichst viele Rotstrahlen abfängt. Auch hinten erhält die Birne einen Farbstoffbelag ¢, ebenfalls ad besten Blau oder Grün, damit nicht der Hinterteil des Reflektors blendendes Licht nach vorn wirft. Der Belag ¢ kann in verschiedener Schichtdicke über den ganzen Teil der Birne ausgebreitet werden., der nicht von den Belägen z und 3 bedeckt ist. Wenn dies geschieht, ist er hinten am dicksten und geht nach vorn in immer dünnere Schichten über, bis er beim Anschluß an den Belag 3 fast durchsichtig ist.To intercept the dazzling rays, the front of the pear is fitted with a thick coating 3 provided of dye, which completely covers the filament to the front. The topping is made blue or green so that it catches as many red rays as possible. The back of the pear is also given a coating of dye ¢, also ideally blue or Green, so that the rear part of the reflector does not throw blinding light forwards. The covering ¢ can be spread over the whole part of the pear in different thicknesses which is not covered by the coverings z and 3. When this happens is it is thickest at the back and passes into ever thinner layers towards the front until it when connecting to the covering 3 is almost transparent.
