Description

Die Erfindung hat einen Reflektor für Lampen und Scheinwerfer mit Gas- oder elektrischem Licht zum Gegenstand, der bei größter Widerstandsfähigkeit gegen Druck und Stoß die günstigsten Bedingungen für die Reflexion der auffallenden Lichtstrahlen bietet. Von den bisher gebräuchlichen Reflektoren sind in optischer Hinsicht die besten die aus Glas hergestellten und mit einemThe invention has a reflector for lamps and headlights with gas or electric light to the object, which is with the greatest resistance to pressure and shock the most favorable conditions for the reflection of the incident light rays offers. Of the reflectors in use up to now, they are the best from an optical point of view those made of glass and with a

ίο Silberspiegel bedeckten. Diese haben aber den Nachteil großen Gewichts, großer Zerbrechlichkeit und Kostspieligkeit. Reflektoren aus unedlem Metall sind zwar unzerbrechlich, werden aber leicht blind und matt. Die Verwendung von edlen Metallen in größerer Menge scheitert an der Kostenfrage. Reflektoren aus emaillierten Metallplatten, wie sie als Lampenschirme vielfach gebräuchlich sind, verschlucken zu viel Licht.ίο covered silver mirror. But these have the disadvantage of great weight, great fragility and great cost. Reflectors made of base metal are unbreakable, but easily become blind and dull. The usage of precious metals in large quantities fails because of the question of cost. Enamelled metal plate reflectors, such as they are widely used as lampshades, swallow too much light.

Die guten Eigenschaften der bisher bekannten Reflektoren ohne ihre Nachteile vereinigt aber ein Reflektor nach vorliegender Erfindung, der in folgender Weise hergestellt wird. Eine Metallplatte von gewünschter Form wird auf der reflektierenden Seite mit einer isolierenden Deckschicht aus Glasuroder Kopallack versehen. Auf dieser Schicht wird aus reduzierenden Lösungen eine Goldoder Silberschicht fixiert, welche die vollkommenste Zurückwerfung des auffallenden Lichtes gewährleistet. Zum Schutz kann der Gold- oder Silberspiegel noch mit einer Kopal- oder Glasurschicht überzogen werden.The good properties of the previously known reflectors are combined without their disadvantages but a reflector according to the present invention made in the following manner will. A metal plate of desired shape is on the reflective side with provided with an insulating top layer of glaze or copal lacquer. On this layer a gold or silver layer is fixed from reducing solutions, which is the most perfect Reflection of the incident light guaranteed. For protection, the gold or silver mirror can also be covered with a copal or glaze layer are coated.
