Description

Die Erfindung betrifft eine Nebelleuchte für Kraftfahrzeuge unter Verwendung einer Flutlichtquelle, z. B. einer Leuchtstoffröhre. Diese Art Lichtquellen sind für die Kraftfahrzeugbeleuchtung allgemein und auch für Nebelleuchten an Kraftfahrzeugen bexemts bekannt. Le=htstöffröhren, deren Längsachse mit der Brennlinie des Reflektors zusammenfallen, sind ebenfalls bekanntgeworden. Die Erfindung schlägt demgegenüber bei der Verwendung von LenchtstoffröhTen als Nebelleuchten zur Erzielung einer besonderen Richtwirkung vor, diese so iin dem perabolischen Längsreflektor anzuordnen, da,ß dessen Brennlinie längs der Oberfläche der Lampe verläuft. Hierdurch werden alle von der Leuchtstofflampe ausgehenden .Strahlen. derart erfaßt, daß sie gerichtet nach vorn austreten. Durch Anordnung von Priismen .in der Reflektoiröffnung kann dann der Strahlenverlauf -weiterhin derart bee'nfl.ußt weirden, .daß er z. B, der Höhe nach begrenzt ist. Das auf diese Weise erzielte ni,ahtblendende Flutlicht läßt die Fahrbahn einerseits gut erkennen, wähnend es andererseits sich bei richtiger Dosierung im Nebel nicht spiegelt.The invention relates to a fog lamp for motor vehicles under Use of a flood light source, e.g. B. a fluorescent tube. That kind of light source are for automotive lighting in general and also for fog lights on motor vehicles bexemts known. Le = htstöffröhren, whose longitudinal axis coincides with the focal line of the reflector coincide have also become known. The invention suggests against this when using fluorescent tubes as fog lights to achieve a special one Directional effect before arranging this so iin the perabolic longitudinal reflector that, ß whose focal line runs along the surface of the lamp. This will all Rays from the fluorescent lamp. detected in such a way that they are directed step forward. By arranging priisms in the reflector opening then the course of the rays -continue to be influenced in such a way that it z. B, the Height is limited according to. The in this way achieved non-dazzling floodlight leaves Recognize the road on the one hand well, while on the other hand it is correct Dosage is not reflected in the mist.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung und isteillt die Nebelleuchte im Schnitt dar. In dem par.abdlischen Längsreflektor i ist die Leuchtstoffröhre 3 derart angeoirdnet, daß ihre Oberfläche mit der Brennlinie zusammenfällt. Die Reflektoröffnung ist durch, eine optische Scheibe verschloisisen., d:ne aus zwei Prismen 4 und der Linse 5 besteht.The drawing illustrates an embodiment of the invention and is part of the fog lamp. In the par.abdlischen longitudinal reflector i the fluorescent tube 3 is arranged in such a way that its surface coincides with the focal line coincides. The reflector opening is closed by an optical disc., d: ne consists of two prisms 4 and the lens 5.
