Description

Die Erfindung betrifft einen Reflektor für Beleuchtungseinrichtungen, welcher aus einem einseitig verspiegelten Metallkörper besteht, der von einem Kühlmittel durchflossen wird.The invention relates to a reflector for lighting devices, which consists of a metal body mirrored on one side, which is made of a coolant is traversed.

Um solche Reflektoren besonders einfach und kostensparend herstellen zu können, wird erfindungsgemäß vorgeschlagen, den Metallkörper des Reflektors als Formgußteil auszubilden, in den das Kühlmittel aufnehmende Leitungen als Ganzes mit eingegossen sind.To make such reflectors particularly easy and cost-saving to be able to, is proposed according to the invention, the metal body of the reflector as Form cast part in which the coolant receiving lines as a whole are cast in.

Auf diese Weise sind zum Ausformen der spiegelnden Reflektorfläche und ebenso zum Ausbilden des Kühlmitteldurchlaufs im Reflektor keinerlei zusätzliche Arbeitsgänge erforderlich. Die genaue Wölbung des Reflektors liegt bereits in der Gußform fest, während die das Kühlmittel führenden Leitungen lediglich in die leere Form so eingelegt zu werden brauchen, daß sie beim Gießen von dem flüssigen Metall völlig umschlossen werden. Die zu verspiegelnde Fläche des fertigen Formgußteils kann nach oberflächlichem Schleifen und Polieren zunächst einen Überzug aus einem Speziallack erhalten, der infolge seiner Oberflächenspannung kleine, durch die Kristallstruktur des Metalls bedingte Unebenheiten ausgleicht. Auf den Lack wird ein Spiegelbelag aufgebracht, der beispielsweise aus einer im Hochvakuum aufgedampften Aluminiumschicht bestehen kann.In this way, the specular reflector surface is formed and also to form the coolant passage in the reflector no additional Operations required. The exact curvature of the reflector is already in the Casting mold firmly, while the lines leading the coolant only in the empty Form need to be inserted so that they are poured from the liquid metal be completely enclosed. The surface of the finished cast part to be mirrored After surface grinding and polishing, a coating can first be made of one Special lacquer obtained, which is small due to its surface tension, due to the crystal structure evens out unevenness caused by the metal. A mirror coating is applied to the paint applied, for example from an aluminum layer vapor-deposited in a high vacuum can exist.

In der nachfolgenden Beschreibung ist die Erfindung an Hand eines Ausführungsbeispiels erläutert. Es zeigt F i g. 1 einen Blick auf die Rückseite des Reflektors, F i g. 2 einen Schnitt durch den Reflektor nach der Linie II-11 von F i g. 1.In the following description, the invention is based on one Embodiment explained. It shows F i g. 1 take a look at the back of the reflector, FIG. 2 shows a section through the reflector along the line II-11 from F i g. 1.

Der Reflektor 1 besteht aus einem im Formgußverfahren hergestellten Metallkörper 2. In diesen ist eine als Rohrspirale 2 ausgebildete Leitung eingegossen, in der ein flüssiges oder gasförmiges Kühlmittel zirkuliert. Die Rohrspirale hat zwei aus der Rückseite des- Reflektors 1 herausragende Stutzen 4 und 5, an die ein Gehäuse oder eine Pumpe üblicher Art angeschlossen ist. Die konkav gewölbte Vorderseite des Reflektors ist mit einem Spiegelbelag 6 versehen, welcher das von einer nicht gezeigten, in eine zentrale Öffnung 7 des Reflektors hineinragenden Lichtquelle erzeugte Licht bündelt und in eine bestimmte Richtung lenkt.The reflector 1 consists of one produced by the molding process Metal body 2. In this a pipe designed as a spiral pipe 2 is cast, in which a liquid or gaseous coolant circulates. The spiral tube has two protruding from the back of the reflector 1 nozzle 4 and 5, to the one Housing or a pump of the usual type is connected. The concave front the reflector is provided with a mirror coating 6, which is not the one shown, projecting into a central opening 7 of the reflector light source The generated light bundles and directs it in a certain direction.
