Abstract

The reflector uses a mirror which is supported to allow its adjustment in all directions under control of a processor-controlled automatic setting drive, so that the received sunlight is reflected on to a defined surface. The processor is controlled by a basic programme for operation of the setting drive in dependence on the date, the time of day and the latitude and longitude of the geographical position of the reflector, with selective manual control. A remote-controlled wiper system can be used for cleaning the surface of the reflector.

Description

Spiegelvorrichtungen und Nachführungssysteme für Projektionen auf Himmelskörper gibt es für den astronomischen Anwendungsbereich und auch zur Konzentration von Sonnen licht zum Zwecke der Bereitstellung oder Umwandlung thermischer Energie.Mirror devices and tracking systems for projections on celestial bodies exist it for the astronomical application and also for the concentration of suns light for the purpose of providing or converting thermal energy.

Zum Zwecke der Illuminierung verschatteter Räume und Flächen sind solche Nachführungssysteme nur bedingt einsetzbar, da der Aufstellungsort für die Spiegelreflektoren durch die örtlichen Gegebenheiten diktiert wird. Der Aufstellungsort muß in freier Linie zu ganz jährig möglichen Sonnenbahnen sowie zu den Beleuchtungsflächen stehen und in erwünschten und vernünftigen Winkeln zu diesen. Oft gelingt es auf Grund der Örtlichkeiten einen solchen Platz nur an relativ unzugänglichen Stellen zu finden, auf fremden Grundstücken, an Brandmauern, auf Dächern, viele Dutzend Meter vom Anwender entfernt. Durch eine starre Nachführung ist keine bedarfsorientierte Nutzung des Reflektors zu realisieren, ständige Einstellungsänderung vor Ort und die Reinigung der Spiegel, um den Wirkungsgrad zu erhalten, würden sich als zu aufwendig erweisen.Such tracking systems are for the purpose of illuminating shaded rooms and surfaces can only be used to a limited extent because the installation location for the mirror reflectors the local conditions are dictated. The site must be in full line to whole year-round possible sun tracks as well as to the lighting areas and in desired and reasonable angles to these. It often works because of the Locations to find such a place only in relatively inaccessible places foreign properties, on firewalls, on roofs, many tens of meters from the user away. Rigid tracking means there is no need-based use of the reflector to realize constant change of settings on site and cleaning the mirrors in order Maintaining efficiency would prove to be too complex.

Die flexible Nutzung der Spiegelvorrichtung wird durch die in Patentanspruch 1 aufgezeig ten Merkmale ermöglicht: Einstellungen, Speicherung und Bedienung als Fernbedienung, sowie eine Grundprogrammierung, welche nach Einmessen der zu beleuchtenden Flächen die Reflexion des gewünschten Astronomischen Objekts auf diese innerhalb eines ge wünschten Zeitraumes durch die Ausrichtung des Spiegel gewährleistet.The flexible use of the mirror device is shown by the claim 1 Features: Settings, storage and operation as a remote control, as well as a basic programming, which after measuring the areas to be illuminated the reflection of the desired astronomical object on it within a ge desired period of time guaranteed by the alignment of the mirror.

Der Anwender ist nunmehr in der Lage, - sofern die Bewölkung es zuläßt -, das Sonnenlicht auf unterschiedliche Flächen oder Räume zu schalten, ohne die Einstellung an der Anlage selbst vornehmen zu müssen. Hat der Bewohner einer dunklen nach Norden gerichteten Hinterhauswohnung mit drei Räumen nur eine Spiegelvorrichtung zur Verfügung, so kann er doch in der Sonne aufwachen, dann in der Küche in der Sonne frühstücken und danach im Arbeitszimmer am Schreibtisch in der Sonne arbeiten. Nachts gefällt es ihm vielleicht, vorn Balkon aus den Vollmond über dem Dach zu sehen. Nach Bedarf kann er den Spiegel auch wegklappen.The user is now able, if the clouds allow it, sunlight switch to different areas or rooms without the setting on the system to do it yourself. Has the inhabitant of a dark north-facing Back house apartment with three rooms only one mirror device available, so can he wake up in the sun, then have breakfast in the kitchen in the sun and afterwards work in the sun in the study at the desk. He might like it at night, Front balcony to see the full moon over the roof. If necessary, he can use the mirror also fold away.

In Patentanspruch 2 sind Modifikationen angemeldet, die die Einsetzbarkeit der Anlage und auch ihre Wartungsfreundlichkeit verbessern:In claim 2, modifications are registered that the usability of the system and also improve their ease of maintenance:

- To ensure constant efficiency, a windscreen washer system enables which is remotely controllable as claimed in claim 1, the cleaning of the mirror surface.
- If there is a desire to optimize the beam direction, the entire game can Gel device variable in location depending on the time of day on rails Angular range can be moved, remote controlled as in claim 1.
- In order to irradiate a larger area than it is in almost parallel sunlight through the Mirror size is specified, a device is installed that allows the game Gel limited to deform convex. Of course, this also enables a gentler irradiation area with better use of available resources. Interes sant this is z. B. for garden bars and street cafes, where the guests are neither in the gaudy Sun still want to sit in the absolute shade and therefore a better dosage and Distribution of light becomes possible.

Claims

1. Mirror device for illuminating shady rooms and areas, in which the mirror is mounted so that it can be moved continuously in all directions, the setting being made automatically via processor-controlled actuators so that the received light reflects on a certain defined area ,
characterized,
that the controlling processor has basic programming, which, after entering the parameters date, time, longitude and latitude of the location and hand-controlled measurement of the target area to be tanned, calculates the angle setting for controlling the mirror, so that the sun's rays on the entire time of day Target area to be reflected;
that in addition to this auto control, manual control is possible,
that the processor can save radiation target areas and can control another stored radiation area at any time,
that setting, storage and operation by remote control, e.g. B. via radio.

2. Mirror device according to protection claim 1, characterized in
that the mirror, which is expediently mostly circular in this arrangement, is convexly curved, so that the irradiation area increases with increasing distance;
that the mirror, which is expediently mostly circular in this arrangement, can be variably curved by a pin that pushes the center of the mirror, which has limited elastic properties, from behind to the outside until the desired light scattering is achieved. The mechanism for this is to be controlled by remote control as in protection claim 1;
that a mirror washer, for example with wiper blades and spraying device, which is also controlled by remote control, is mounted;
that the entire device is mounted on rails and thus variable in location to a limited extent, the location changes being programmable,
that instead of the projection of the sun, that of the moon or other astronomical objects is adjustable.
