Description

Elektrische Taschenlampe mit Kompaß Es ist bekannt, daß sich, Licht in Glasstähen und Wasserstrahlen fortleiten läßt, da es an deren Langswanclungen total reflektiert wird und deshalb nicht durch diese hindurchgeht (Colladonsches Prinzip).Electric flashlight with compass It is known to be, light in glass rods and water jets, since it is due to their long swellings is totally reflected and therefore does not go through it (Colladonsches Principle).

Die Erfindung betrifft eine neue praktische Anwendung dieses Prinzips und besteht in dner elektrischen Taschenlampe mit Kompaß, bei welcher das Licht der Glühlampe dem Kornpaß mittels eines stabförmiggen, lichtdurchlässigen und einen höheren Lichtbrechungskoeffizienten als seirie Umgebung besitzenden Körpers, eines sogenannten stabförmigen Lichtleiters zugeführt wird. In der Zeichnung ist der Erfind-ungsgegenstand in einem Ausfüh.-rungsb eispiel ausgeführt. Die Zeichnung zeigt in Abb. i den senkrechten Schnitt und) in Abb. 2 die Aufsicht von oben. E ine Tasch-enlampe in der »bekannten Stabforra enthält in einem seitlichen Ansatz der Hülse-4 den LichtleiterE, welcher das Licht der Birne von dem Raum:B nach dem Raum.C, der den Kompaß enthält, leitet. Zwischen Raurn, B und C ist in bekannter Weise die Batter!eD eingeschoben. Die Beleuchtungsvorrichtung gemäß der Erfindung ermöglicht das gleichzeitige Ablesen einer Landkarte und des Kompasses im Dunkeln zur Richtung i i "sorienti-erung oder Peilung.The invention relates to a new practical application of this principle and consists in the electric flashlight with compass, in which the light from the incandescent lamp is fed to the grain pass by means of a rod-shaped, translucent body with a higher refractive index than its surroundings, a so-called rod-shaped light guide. The subject of the invention is shown in an exemplary embodiment in the drawing. The drawing shows in Fig. I the vertical section and) in Fig. 2 the plan view from above. A pocket lamp in the "well-known rod shape" contains the light guide E , which guides the light of the bulb from the room: B to the room C, which contains the compass, in a lateral attachment of the sleeve-4. The batter! ED is inserted between rooms, B and C in a known manner. The lighting device according to the invention allows the simultaneous reading of a map and the compass in the dark to the direction ii "sorienti-augmentation or bearing.

Als Liehtleiter eignen sich au#,er Glasstäben auch Stäbe aus glasartigen Kunststoffen, wie Bakelite, -Harnstoff-Fori-naldehy-d-Konde#nsate u. dgl.Besides glass rods, rods made of glass-like materials are also suitable as ladder Plastics, such as Bakelite, -urea-Fori-naldehy-d-Konde # nsate and the like.

Die Längswandungen,der Lichtleiter können mit einem lichtundurchlässigen oder spiegelnden Belag versehen werden. Der letztere verursacht eine Reflexion auch bei sehr starken Krümmungen der Leiter.The longitudinal walls of the light guide can be covered with an opaque or reflective coating. The latter also causes a reflection in the case of very strong curvatures of the conductor.

Statt eines Lidhtleiters können auch zwei oder mehrere angebracht werden.Instead of one eyelid guide, two or more can be attached will.

Die Enden der Lichtleiter können linsenförmig gestaltet sein. Ferner kann -luirch geeignete Färbung der Lichtleiter eine getonte Beleuchtung erzielt werden.The ends of the light guides can be designed lens-shaped. Further -Luirch suitable coloring of the light guides can be used to achieve toned lighting will.
