Description

Lichtsignal mit parabolischem Reflektor. Im Hauptpatent 424o62 ist ein Lichtsignal mit parabolischem Reflektor beschrieben, welches durch Anordnung von Licht absorbierenden Flächen ein Reflektieren der von außen eintretenden parallelen Lichtstrahlen verhindert.Light signal with parabolic reflector. The main patent 424o62 is described a light signal with a parabolic reflector, which by arrangement of light-absorbing surfaces a reflection of the parallel entering from outside Prevents light rays.

Gemäß der Erfindung kann man an Stelle der Licht absorbierenden Flächen auch Licht zerstreuende Flächen verwenden. Man kann dies gemäß der Erfindung z. B. dadurch erreichen, daß man an Stelle der bisher verwandten nicht mattierten Lampen rnattierte Lampen verwendet.According to the invention, instead of the light-absorbing surfaces also use light-diffusing surfaces. You can do this according to the invention, for. B. can be achieved by replacing the previously used non-frosted lamps Nickel-plated lamps used.

In der Abbildung ist ein derartiges Lichtsignal als Beispiel dargestellt. i ist ein parabolischer Reflektor, 2 ist eine mattierte Lampe; mit 3 sind die von außen eintretenden parallelen Lichtstrahlen bezeichnet. Aus der Zeichnung ist ersichtlich, daß alle Strahlen, die auf den Reflektor von außen auftreffen, ehe sie wieder austreten können, die mattierte Lampe treffen müssen, Durch das mattierte Glas werden sie nun zerstreut, so daß keine wesentliche Lichtwirkung mehr nach außen dringt. je nach Ausbildung des Reflektors kann man eine voll oder nur teilweise mattierte Lampe verwenden.Such a light signal is shown as an example in the figure. i is a parabolic reflector, 2 is a frosted lamp; 3 denotes the parallel light rays entering from the outside. From the drawing it can be seen that all rays that strike the reflector from the outside, before they can exit again, must hit the frosted lamp. They are now scattered by the frosted glass, so that no more significant light effects penetrate to the outside. Depending on the design of the reflector, a fully or partially frosted lamp can be used.

Claims (1)

PATrNT-ANSPRUCH: Lichtsignal mit parabolischem Reflektor nach Patent 424o62, dadurch gekennzeichnet, daß zwecks Verhinderung des Aufleuchtens des Reflektors bei nicht brennender Lampe durch von außen kommende Lichtstrahlen an Stelle der das Licht absorbierenden Flächen das Licht zerstreuende Flächen in Gestalt von ganz oder teilweise mattlerten Lampen verwendet werden, die auf der den Reflektorflächen diametral gegenüberliegenden Seite der Lichtquelle angeordnet sind. PATRNT CLAIM: Light signal with parabolic reflector according to patent 424o62, characterized in that in order to prevent the reflector from lighting up when the lamp is not burning by light rays coming from outside instead of the surfaces absorbing the light, surfaces in the form of completely or partially matted lamps are used, which are arranged on the side of the light source diametrically opposite the reflector surfaces.
