Description

Fremdlichtsichere Leuchte, insbesondere für Kraftfahrzeuge Bei Signalleuchten an Kraftfahrzeugen findet man häufig Vorkehrungen, durch die das Vortäuschen von Signalen durch Fremdlicht unterbunden werden soll. Zu diesem Zweck rauht man entweder die Oberfläche der Signalleuchte auf, oder man ordnet die Lichtquelle verdeckt an. Bei einer bekannten Ausführungsform ist das Farbfilter im Verhältnis zu der farblosen Abdeckscheibe klein gehalten. Es ist weiterhin bekanntgeworden, die farbigen. Fahrtrichtungsanzeigelampen von Straßenbahnen mit einer zusätzlichen Elfenbeinlackierung zu versehen, so daß sie in nicht eingeschaltetem Zustande farblos erscheinen.Ambient light-proof light, in particular for motor vehicles For signal lights on motor vehicles one often finds precautions by which the pretense of Signals caused by extraneous light are to be suppressed. For this purpose one either roughened the surface of the signal light, or you can arrange the light source in a concealed manner. In a known embodiment, the color filter is in relation to the colorless one Cover plate kept small. It has also become known the colored ones. Direction indicator lamps to provide trams with an additional ivory coating so that they appear colorless when not switched on.

Diese bekanntgewordenen Maßnahmen bedingen jedoch in allen Fällen eine wesentliche Erhöhung der Glühlampen-Wattzahl, ein Umstand, der sich insbesondere bei Kraftfahrzeugen infolge ihres heschränkten Stromhaushalts ungünstig bemerkbar macht.However, these known measures require in all cases a substantial increase in incandescent wattage, a circumstance that is particularly evident in motor vehicles due to their limited electricity budget unfavorably noticeable power.

Unter Vermeidung der genannten Nachteile werden farbige Signalleuchten für Kraftfahrzeuge dadurch fremdlichtsicher gemacht, daß man erfindungsgemäß die farblose durchsichtige Leuchtkuppel auf ihrer Innenseite mit einer halbdurchlässigen, im Aufdampfverfahren hergestellten Spiegelschicht versieht. Die derart angeordnete Spiegelschicht hat den Vorteil, daß sie den größten Teil der von außen auftreffenden Fremdlichtstrahlen reflektiert, während die austretenden Strahlen von dieser »dünnen« Schicht nur wenig absorbiert werden. Eine solche Schicht ist außerdem unempfindlich gegen die Einwirkung des ultravioletten Anteils des Sonnenlichts, d. h. sie verändert sich nicht, wie dies z. B. bei Farbanstrichen der Fall ist.Colored signal lights are used while avoiding the disadvantages mentioned for motor vehicles made safe against external light that according to the invention the colorless transparent luminous dome on its inside with a semi-permeable, Provides mirror layer produced in the vapor deposition process. The so arranged The mirror layer has the advantage that it covers most of the outside impact Extraneous light rays are reflected, while the exiting rays from this "thin" Layer are only slightly absorbed. Such a layer is also insensitive against the action of the ultraviolet part of sunlight, d. H. she changed not like this z. B. is the case with paints.

Die Lichtaustrittsfläche der Leuchte erscheint nach außen metallisch glänzend, so daß das bei Signalgabe austretende farbige Licht besonders auffällig ist.The light emitting surface of the lamp appears metallic to the outside shiny, so that the colored light emitted when the signal is given is particularly noticeable is.

Die Spiegelschicht wird man im Aufdampfverfahren auf die Abdeckscheibe aufbringen, um so@ einen innigen Kontakt zwischen dem durchsichtigen Werkstoff und der Spiegelschicht zu erhalten. Gegebenenfalls kann man das Farbfilter unmittelbar auf die halbdurchlässige Spiegelschicht aufbringen. Die Zeichnung veranschaulicht ein Ausführungsbeispiel der erfindungsgemäßen fremdlichtsicheren Leuchte im Schnitt. Die aus farblosem Werkstoff bestehende Kuppel 1, die die mit einem farbigen Überzug 4 versehene Lichtquelle 3 umschließt, besitzt erfindungsgemäß auf ihrer Innenseite den halbdurchlässigen Spiegel 2.The mirror layer is applied to the cover plate by vapor deposition apply so as to @ an intimate contact between the transparent material and the mirror layer. If necessary, you can use the color filter directly Apply to the semi-permeable mirror layer. The drawing illustrates an embodiment of the light-proof lamp according to the invention in section. The dome 1 made of colorless material, which is covered with a colored coating 4 provided light source 3 encloses, according to the invention has on its inside the semi-transparent mirror 2.
