 der der Glühlampe zusaunnenfällt. 



   Es sind derartige Fahrzengscheinwerfer bekannt. bei welchen der aus einem oder mehreren Stücken bestehende Glühfaden der elektrischen Lampe unsymmetrisch, beispielsweise schräg zur Reflektorachse angeordnet ist. wobei die untere Hälfte der Birne mattiert ist. Es hat sich nun herausgestellt, dass sich ein Effekt, welcher der Diffusionswirkung mattierter

   erfindungsgemäss   angeordneten Glühfaden, die Fig.   zip   zeigen verschiedene Ausführungsformen der   Glühfadenanordnung   nach der Erfindung und schliesslich Fig.

   24 einen Scheinwerfer mit   erfindungsgemäss     angeordneten Glühfäden, bei welchem jedoch   die Achsen der Lampe und des Reflektors nicht in einer Linie liegen. 



   Wie ersichtlich, fällt bei den Anordnungen nach den Fig. 1 und 8 die   Achse-Y-Y

 den übrigen Ausführungsformen mit Ausnahme von Fig. 24. Lampe und Rotationsreflektor können beliebige Form haben, letzterer beispielsweise die parabolische. 



   Wesentlich ist im Sinne der Erfindung, dass der Glühfaden c nicht symmetrisch zur besagten Achse steht, dahingegen kann er   zn   beiden Seiten des Schnittpunktes von Glühfaden und Reflektorachse entweder symmtrisch verlaufen oder unsymmetrisch. Eine der einfachsten Formen ist Die. bei welcher der Faden schräg gestellt ist (Fig. 8. symmetrisch in

   bestehender Glühfaden   in bezug auf die Reflektorachse   unsymmetrisch   angeordnet, beispielsweise schräg gestellt ist, dadurch gekennzeichnet, dass die in Verbindung mit dieser Glühfadenanordnung verwendete Birne vollständig hell, d. h. an keiner Stelle mattiert ist.

  Headlights with electric light bulb.
 EMI1.1
 who falls for the light bulb.



   Such vehicle headlights are known. in which the filament of the electric lamp, which consists of one or more pieces, is arranged asymmetrically, for example at an angle to the reflector axis. the lower half of the pear is frosted. It has now been found that there is an effect which is more matt than the diffusion effect
 EMI1.2
 Light intensity is not affected. as is the case with fully or partially frosted pears.
 EMI1.3
   According to the invention arranged filament, Fig. Zip show different embodiments of the filament arrangement according to the invention and finally Fig.

   24 a headlight with filaments arranged according to the invention, but in which the axes of the lamp and the reflector are not in one line.



   As can be seen, in the arrangements of FIGS. 1 and 8, the axis-Y-Y falls
 EMI1.4
 the remaining embodiments with the exception of FIG. 24. The lamp and the rotating reflector can have any shape, the latter for example being parabolic.



   It is essential in the context of the invention that the filament c is not symmetrical to the said axis, whereas it can either run symmetrically or asymmetrically on both sides of the intersection of the filament and reflector axis. One of the simplest forms is Die. in which the thread is inclined (Fig. 8. symmetrically in

 EMI2.1
   existing filament is arranged asymmetrically with respect to the reflector axis, for example inclined, characterized in that the bulb used in connection with this filament arrangement is completely bright, i. H. is not matted anywhere.
