  Scheinwerfer. 



   Erfindungsgemäss wird die negative Elektrode von Scheinwerfern, insbesondere von solchen für Projektionszwecke, mit einem Zusatz von   Leuchtstoffen   versehen, während die positive Elektrode keine Leuchtstoffe enthält. Es hat sich gezeigt, dass durch diese Anordnung eine bedeutend grössere Lichtausbeute erzielt wird, als wenn man die positive Elektrode als Effektkohle ausbildet oder positive und 
 EMI1.1 
 ein besseres Licht. Besonders stark tritt dies hervor, wenn es sich darum handelt, ein rein weisses Licht zu erzeugen.

   Verwendet man die hiefür   üblichen Elektroden,   die hauptsächlich Lanthanverbindungen enthalten, so ergeben diese in Verbindung mit der positiven Elektrode ein Licht, das erheblich geringer 
 EMI1.2 
 die negative Elektrode, so erhält man eine ganz bedeutend gesteigerte Lichtausbeute und ein   blä dich   weisses Licht, während das Licht zweier Reinkohlen etwas gelblichweiss ist. Besonders für Kinolampen mit horizontaler positiver Kohle und dazu geneigter negativer bedeutet diese Anordnung einen erheblichen Vorteil. 



   PATENT-ANSPRÜCHE :
1. Scheinwerfer, dadurch gekennzeichnet, dass als negative Elektrode eine Effektkohle, als positive Elektrode eine Reinkohle verwendet ist.

  Headlights.



   According to the invention, the negative electrode of headlights, in particular those for projection purposes, is provided with an additive of phosphors, while the positive electrode does not contain any phosphors. It has been shown that this arrangement achieves a significantly greater light yield than if the positive electrode is designed as an effect carbon or positive and
 EMI1.1
 a better light. This is particularly pronounced when it comes to generating a pure white light.

   If the electrodes that are customary for this purpose, which mainly contain lanthanum compounds, are used, these, in conjunction with the positive electrode, result in a considerably lower light
 EMI1.2
 the negative electrode, one obtains a considerably increased light yield and a pale white light, while the light from two pure coals is somewhat yellowish-white. This arrangement is a considerable advantage, especially for cinema lamps with horizontal positive carbon and inclined negative ones.



   PATENT CLAIMS:
1. Headlight, characterized in that an effect carbon is used as the negative electrode and a pure carbon is used as the positive electrode.
 EMI1.3
