Description

Schiffs-Positions- oder sonstige Fahrzeuglaternen. Die roten und grünen und hellen Positionslaternen auf Schiffen haben Fresnellinsen, welche die Eigenschaft bekanntlich besitzen, alle vom Brennpunkte ausgehenden Strahlen parallel aus der Linse austreten zu lassen. Da die Lichtquelle aber im allgemeinen nicht punktförmig, sondern vertikal gestreckt ist -bei Petroleumbrennern, welche bei den meisten Schiffen nur in Frage kommet<, bis zu 30 rnm -, so ist tatsächlich eine Streuung von je bis zu 71/z° nach oben und unten vorhanden.Ship position or other vehicle lights. The red and green and bright navigation lights on ships have Fresnel lenses, which are known to have the property of allowing all rays emanating from the focal point to exit the lens in parallel. However, since the light source is generally not point-shaped, but vertically stretched - up to 30 mm in the case of petroleum burners, which can only be used on most ships - there is actually a spread of up to 71 / z ° upwards and downwards present below.

Segelschiffe und auch Dampfer gelegentlich haben aber zuweilen größere Neigungen als 7i/2°, und infolgedessen würden deren Laternen dann in der Horizontalen nicht mehr zu sehen sein, und die Folge davon könnten dann unter Umständen schwerwiegende Kollisionen mit anderen Fahrzeugen sein.Sailing ships and also steamers occasionally have larger ones Inclinations as 7i / 2 °, and consequently their lanterns would then be horizontal can no longer be seen, and the consequences of this could then be serious under certain circumstances Collisions with other vehicles.

Um eine größere' Streuung herbeizuführen, muß die Lichtquelle verlängert werden. Bei einem einfachen Petroleumbrenner ist aber nur eine Flammenhöhe von etwa 30 mm zu erzielen, und nach längerem Brennen wird diese überdies noch verkürzt.In order to bring about a greater 'scattering, the light source must be lengthened. With a simple kerosene burner, however, only a flame height of about 30 mm can be achieved, and after prolonged burning it is also shortened.

Nach der vorliegenden Erfindung werden im Brennpunkte der Linse nun mehrere Lichtquellen vertikal oder treppenförmig übereinander angeordnet; in Abständen voneinander und in einer Anzahl entsprechend der jeweiligen Anforderung an Streuung und Lichtstärke der Laterne.According to the present invention, the focal points of the lens are now several light sources arranged vertically or in steps one above the other; at intervals from each other and in a number corresponding to the respective requirements for dispersion and light intensity of the lantern.

Claims (1)

PATENTANSPRUCH: Schiffs-Positions- oder andere Fahrzeuglaternen mit Fresnellinsen, dadurch gekennzeichnet, daß zwecks Herbeiführung einer größeren oder geringeren Streuung mehrere Lichtquellen in der Nähe der Linsenbrennpunkte vertikal oder treppenförmig übereinanderliegend angeordnet sind und in ihrem Abstand voneinander verändert werden können. PATENT CLAIM: Ship position or other vehicle lanterns with Fresnel lenses, characterized in that several light sources are arranged in the vicinity of the lens focal points vertically or in steps and can be changed in their distance from one another in order to bring about greater or lesser scattering.
