Description

Sicherung für Lichtsignaleinrichtungen gegen falsche Signalangabe durch Fremdlicht Bei farbigen und weißen Lichtsignalen, wie Blinkleuchten und anderen Lampen an Fahrzeugen, Verkehrsampeln und Warnlichtern, besteht die doppelte Aufgabe, das Signalzeichen gegen Fremdlichtüberblen.dung und/oder gegen falsche Signalgabe durch den Fremdlichteinfluß zu schützen, damit das Signal auffällt, aber nicht vorgetäuscht wird. Es ist bekannt, Farbfilter mit großen oder geraubten oder getrübten Hüllen zu umgeben. Die schwächen jedoch das Signallicht, fördern also die Überblendung. Auch wurde vorgeschlagen, vor das Filter eine Schutzschicht in Gegenfarbe zu legen; deren Widerschein im Fremdlicht kann aber das Signal überdecken.Protection for light signal devices against incorrect signal indication by extraneous light With colored and white light signals such as flashing lights and others Lamps on vehicles, traffic lights and warning lights have the dual task of the signal against extraneous light fading and / or against incorrect signaling to protect by the influence of extraneous light so that the signal is noticeable, but not faked will. It is known to use color filters with large or stolen or clouded envelopes to surround. However, they weaken the signal light, thus promoting cross-fading. It was also proposed to put a protective layer in the opposite color in front of the filter; however, their reflection in the external light can mask the signal.

Die Erfindung geht von der Tatsache aus, daß das Signallicht vorwiegend gebündelt und senkrecht das Fremdlicht zerstreut und großenteils schräg durch das Filter geht, andererseits von der Erscheinung, daß wechselnde Lagen dünner Glas- und Luftschichten senkrecht einfallendes Licht durchlassen, schräg einfallendes aber Wegspiegeln. Erfindungsgemäß werden mehrere abwechselnde Lagen dünner Stoffe von hoher und niedriger Brechungszahl, wie Kunststoffband und Luft, im Strahlengang des Lichtes an der Signaleinrichtung vorgesehen.The invention is based on the fact that the signal light predominantly bundled and vertically scattered the extraneous light and largely obliquely through the Filter, on the other hand, is based on the phenomenon that alternating layers of thin glass and layers of air let through perpendicularly incident light, obliquely incident light but mirroring away. According to the invention, several alternating layers of thin fabrics are made of high and low refractive index, such as plastic tape and air, in the beam path of the light provided on the signaling device.

Wird beispielsweise ein dünnes Polystyrolband durch Wickeln, Falten oder Schichten, Verkleben an den Kanten oder Umbinden mit durchsichtigem Werkstoff zu mehreren Lagen mit Luft- oder sonstigen niedriger brechenden Zwischenschichten vereinigt, außen nötigenfalls durch Lack, Glashülle od. dgl. vor Wetter geschützt, und gegebenenfalls auf dem Färliülter befestigt, so- erhält man einen Schutz gegen Fremderregung, der das Signal wenig schwächt.For example, a thin polystyrene tape is made by winding, folding or layering, gluing on the edges or binding with transparent material to several layers with air or other lower refractive index intermediate layers united, if necessary protected from the weather by varnish, glass cover or the like, and if necessary attached to the woolen sleeve, one obtains a protection against external excitation that weakens the signal a little.

Statt dünner Platten oder Bänder kann man auch Lagen von Glasfäden verwenden, so daß eine Breitenstreuung erzielt wird. Auch kann innerhalb der Schutzschicht eine dünne Farbschicht ange= bracht werden, die von der Signalfarbe einschließlich Weiß deutlich abweicht. Die Schutzkörper können auch in Platten, Stangen oder Blöcken gefertigt und nach Bedarf zerlegt werden. Dabei werden die Lagen zweckmäßig gepreßt und die Kanten finit Aceton oder einem anderen Lösungsmittel bestrichen. Zum Befestigen des Schutzkörpers auf dem Filter kann etwa ein quer geklebtes Polystyrolband dienen.Instead of thin plates or strips, you can also use layers of glass threads use so that a latitude spread is achieved. Also can be inside the protective layer a thin layer of paint must be applied, including that of the signal color White differs significantly. The protective bodies can also be in plates, rods or blocks can be manufactured and dismantled as required. The layers are expediently pressed and the edges were painted with finite acetone or another solvent. To attach For example, a polystyrene tape glued across the protective body on the filter can be used.

Erfahrungsgemäß ist es nicht erforderlich, dieganze Fläche des Farbfilters mit der Schutzschicht zu bedecken.Experience has shown that it is not necessary to cover the entire surface of the color filter to cover with the protective layer.
