 geschoben werden, dass nur ein möglichst kurzer unterer Teil des Glaskolbens, der sich nicht schwärzt, schattengebend wirkt, wobei trotzdem die Forderung erfüllt ist, dass die   Leuchtdrahtfläche   senkrecht

 Spiegels her so in denselben eingeschoben werden, dass bei senkrechter Stellung der   Glühdrahtebene : J   zur Spiegelachse 4, die kleine Leuchtfläche in die optisch günstigste Stellung, also etwa in den Brennpunkt gestellt werden kann. Hiebei liegt die Fassung ausserhalb des Lichtbündels so, dass die schattenwerfenden Teile auf die Tragdrähte 5 beschränkt sind, da die schwache Schattenwirkung des Glaskörpers 2 kaum merkbar ist. 



   Bei langen zylindrischen Glaskolben wirkt hiebei der Umstand günstig, dass die   Schwärzung   desselben nur im oberen Teil eintritt, derselbe also bei Lampen, die wesentlich länger als der Öffnunghalbmesser des Spiegels sind, nicht in den Lichtstrom fällt. 



   Fig. 5 zeigt die Anwendung einer Glühlampe mit teilweiser   Innenverspiegelung   7. 



   Das beschriebene Beleuchtungssystem kann beispielsweise als Scheinwerfer oder auch als Lampen- 
 EMI2.2 
 wendet werden. Als Spiegel können diejenigen der bekannten Scheinwerfer der Firmen Bosch und Zeiss unmittelbar Verwendung finden. 



   PATENT-ANSPRÜCHE :
1. Beleuchtungssystem, gekennzeichnet durch die Kombination eines Scheinwerferspiegels mit möglichst kleinem Abstand des Brennpunktes vom Spiegelscheitel, mit einer langzylindrischen Glühlampe mit in einer Ebene angeordneten Glühdrahtwindungen, deren Ebene geneigt zur Lampenachse steht.

 be pushed so that only as short a lower part of the glass bulb as possible, which does not blacken, has a shadow-giving effect, although the requirement that the filament surface is vertical is met
 EMI2.1
 The mirror can be inserted into the same so that when the filament plane is in a vertical position: J to the mirror axis 4, the small luminous surface can be placed in the most optically favorable position, i.e. in the focal point. The socket is outside the light beam in such a way that the shadow-casting parts are limited to the supporting wires 5, since the weak shadow effect of the glass body 2 is hardly noticeable.



   In the case of long cylindrical glass bulbs, the fact that the blackening of the same only occurs in the upper part is beneficial, i.e. the same does not fall into the luminous flux in lamps that are significantly longer than the opening radius of the mirror.



   FIG. 5 shows the use of an incandescent lamp with a partial internal mirror coating 7.



   The lighting system described can be used, for example, as a headlight or as a lamp

 be turned. Those of the known headlights from Bosch and Zeiss can be used directly as mirrors.



   PATENT CLAIMS:
1. Lighting system, characterized by the combination of a headlight mirror with the smallest possible distance of the focal point from the mirror apex, with a long cylindrical incandescent lamp with filament windings arranged in one plane, the plane of which is inclined to the lamp axis.

 

Claims (1)

2. Beleuchtungssystem nach Anspruch 1, gekennzeichnet durch die Verwendung eines Scheinwerferspiegels von kleinerem Öffnungshalbmesser als der Abstand der Glühdrahtfläche von der Lampenfassung, bei dem die Lampe von der Öffnung des Spiegels her derart schräg eingeführt, dass die Leuchtdrahtfläche in dem Brennpunkt, und die Lampenfassung ausserhalb der Öffnung des Spiegels zu stehen kommt. EMI2.3 2. Lighting system according to claim 1, characterized by the use of a headlight mirror with a smaller opening radius than the distance between the filament surface from the lamp socket, in which the lamp is inserted obliquely from the opening of the mirror in such a way that the filament surface is in the focal point and the lamp socket is outside the opening of the mirror comes to a standstill.
