Abstract

The arrangement collects light from the roof and uses it at desired points in a house. A parabolic mirror (1) mounted on the roof is used to focus the light, which is directed into a parallel beam by a second, smaller mirror (2). The light is passed to the interior of the house via fibreglass cables (3).

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the Preamble of claim 1.

Um Strom einzusparen, wird oft versucht, das Sonnenlicht auszunutzen.To save electricity, sunlight is often tried to take advantage of.

Es ist bekannt, Vorrichtungen auf Dächern von Gebäuden anzubringen, die das Sonnenlicht ins Haus bringen. Die aus England kommende "Sun Pipe" ist ein Beispiel hierfür. Jedoch sind hier nur sehr begrenzte Distanzen zu überwinden. Außerdem nimmt sie sehr viel Platz in Anspruch. Zudem sind fast keine Kurven bei der Leitung des Lichts möglich. Sie kann auch nicht nach der Sonne ausgerichtet werden.It is known devices on roofs of buildings that bring the sunlight into the house. From England's upcoming "Sun Pipe" is an example of this. However there are only very limited distances to be covered here. It also takes up a lot of space. Also are almost no curves possible when directing the light. she cannot be aligned with the sun either.

Aufgabe der Erfindung ist es, eine einfache Vorrichtung zur Verwendung des Sonnenlichts an dunklen Räumen zu schaffen, die platzsparend, weitreichend und flexibel biegbar ist und eine variable Ausrichtung nach der Sonne ermöglicht.The object of the invention is to provide a simple device for Use of sunlight in dark rooms too create space-saving, extensive and flexible bendable and allows a variable orientation towards the sun.

Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst:This task is accomplished by a device with the Features of claim 1 solved:

Parabolspiegel können nach der Sonne ausgerichtet werden. Hohe Distanzen sind überwindbar. Glasfaserkabel können ohne erhebliche Verluste gebogen werden. Keine Glühbirne notwendig. Parabolic mirrors can be aligned with the sun. Long distances can be overcome. Fiber optic cables can can be bent without significant losses. No lightbulb necessary.  

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben, es zeigen:Embodiments of the invention are in the drawings are shown and are described in more detail below, show it:

Fig. 1 senkrechter Schnitt durch Spiegel und Kabel Fig. 1 vertical section through mirrors and cables

Fig. 2 perspektivische Ansicht der Fotowiderstände Fig. 2 perspective view of the photo resistors

Ein großer Parabolspiegel 1 wird auf dem Dach eines Gebäudes befestigt. Ein kleiner Hohlspiegel 2 wird so vor dem Parabolspiegel 1 angebracht, dass ihre beiden Brennpunkte zusammenfallen. In der Mitte des großen Spiegels 1 ist ein Bündel von Glasfaserkabeln 3 montiert, deren beide Enden jeweils abgerundet sind, was zur Zerstreuung des Lichtes führt. Um den Spiegel der Sonne nachfahren zu können, so dass die Strahlen der Sonne rechtwinklig einfallen, werden 2 paar Fotowiderstände 5 an der Vorrichtung montiert, die einen 90°-Winkel miteinander einschließen. Die Fotorwiderstände 5 sind jeweils durch kleine Wände voneinander getrennt, so dass bei schrägem Lichteinfall die einzelnen Widerstände verschieden stark belichtet werden. Diese Information wird dann an zwei Motoren 4 weitergegeben, die die Vorrichtung drehen und kippen, bis die Strahlen der Sonne wieder senkrecht einfallen.A large parabolic mirror 1 is attached to the roof of a building. A small concave mirror 2 is attached in front of the parabolic mirror 1 so that its two focal points coincide. In the middle of the large mirror 1 , a bundle of fiber optic cables 3 is mounted, both ends of which are rounded, which leads to the diffusion of the light. In order to be able to follow the mirror of the sun so that the rays of the sun fall at right angles, two pairs of photo resistors 5 are mounted on the device, which enclose a 90 ° angle with one another. The photoresistors 5 are each separated from one another by small walls, so that the individual resistors are exposed to different intensities in the event of oblique light. This information is then passed on to two motors 4 , which rotate and tilt the device until the rays of the sun fall again vertically.
