Abstract
Description
Die Erfindung betrifft einen Stromversorgungsgenerator für ein Kleingerät, der aus einem aus mehreren Solarzellen zusammengeschalteten Solargenerator besteht.The invention relates to a power supply generator for a small device, the from a solar generator interconnected from several solar cells consists.
Im Handel sind seit längerer Zeit Rundfunkgeräte, Walkmen und andere Klein geräte, z.B. Taschenrechner und Uhren, erhältlich, bei denen zur unmittelbaren Stromversorgung Solarzellenmodule auf der Gehäuse-Oberfläche angebracht sind oder bei denen ein eingebauter Akku bei Bestrahlung des auf der Gehäuse- Oberfläche angebrachten Solarzellenmoduls mit Sonnenlicht oder künstlichen Lichtquellen nachgeladen wird.Radios, walkmen and other small devices have been on the market for a long time devices, e.g. Calculators and watches, available for immediate use Power supply solar cell modules attached to the housing surface or with a built-in rechargeable battery when the housing Surface mounted solar cell module with sunlight or artificial Light sources is recharged.
Dies hat jedoch die Nachteile, daß die Maximalgröße des Solarzellenmoduls durch die Dimensionen des Geräts festgelegt wird, daß bei der Benutzung der Geräte eine ausreichende Bestrahlung des Moduls nicht immer gewährleistet ist, da die Geräte oft in Taschen etc. getragen werden und daß das Gerät bei direkter Bestrahlung, insbesondere bei der Bestrahlung durch künstliches Licht, stark erwärmt werden kann, wodurch die Funktionsfähigkeit eingeschränkt wird.However, this has the disadvantages that the maximum size of the solar cell module is determined by the dimensions of the device that when using the Devices do not always ensure adequate irradiation of the module is because the devices are often carried in bags etc. and that the device is direct radiation, especially when irradiated by artificial light, can be heated up considerably, which limits the functionality becomes.
Zur Vermeidung dieser Nachteile ist erfindungsgemäß vorgesehen, daß der Solargenerator als auf dem Kopf zu tragender Bügel ausgebildet ist.To avoid these disadvantages, the invention provides that the Solar generator is designed as a bracket to be worn on the head.
Durch diese Anordnung und durch die Trennung von Stromversorgung und Klein gerät wird die Größe des Generators nicht mehr durch die Abmessungen des Geräts eingeschränkt, die Solarzellen werden im Betrieb optimal von der Sonne bestrahlt (senkrechte Einstrahlung der Sonne, eine Beschattung kann vermieden werden), außerhalb der Betriebszeit kann der Solargenerator optimal zu einer Lichtquelle ausgerichtet werden und eine unzulässige Erwärmung sowohl des Geräts als auch des Akkus kann verhindert werden.This arrangement and the separation of power supply and small the size of the generator is no longer determined by the dimensions of the Device restricted, the solar cells are optimally operated by the sun irradiated (vertical radiation from the sun, shading can be avoided outside of the operating time, the solar generator can optimally become one Light source are aligned and an inadmissible heating of both the Device as well as the battery can be prevented.
Vorteilhaft ist dabei, den Bügel als Band mehrerer zusammengeschalteter Solarzellen zu gestalten und dieses auf einen Träger aufzubringen, wodurch einerseits die zur Verfügung stehende Fläche und andererseits die Stabilität des Generators erhöht wird.It is advantageous to use the bracket as a band of several interconnected To design solar cells and apply this to a carrier, thereby on the one hand the available space and on the other hand the stability of the generator is increased.
Die Zuleitungen des Generators werden vorzugsweise in den schmalen Bügelzu leitungen integriert.The leads of the generator are preferably in the narrow bracket integrated lines.
Geräte mit eingebautem Akku ohne Solarzellen können über einen Ladeadapter zu einem solarstromversorgten Gerät erweitert werden. Bei Geräten mit bereits eingebauter Solarstromversorgung kann der beschriebene Solargenerator als zu sätzliche Stromversorgung dienen.Devices with built-in rechargeable batteries without solar cells can use a charging adapter can be expanded to a solar-powered device. For devices with already built-in solar power supply, the described solar generator as too additional power supply.
Im folgenden werden 2 Ausführungsbeispiele dargestellt:Two exemplary embodiments are shown below:
Fig. 1 zeigt einen Stromversorgungsgenerator für ein Rundfunk- oder Kassetten gerät (6) mit Kopfhörerwiedergabe. Die Solarzellen (1) sind hierbei auf einem gebogenen bandförmigen Träger (2) angebracht, der vorzugsweise aus bruch festem Kunststoff besteht; an den beiden Seiten des Trägers sind je 2 Stege (3) befestigt, an denen Lautsprecher (4) angebracht sind. Auf den Solarzellen wird eine lichtdurchlässige Schutzschicht angebracht, die beispielsweise aus einer Kunststoffolie oder einem lichtdurchlässigen Kunstharz besteht. Die Stromversorgung des Akkus im Gerät (6) erfolgt, ausgehend von Zuleitungen auf der Ober- und Unterseite der Solarzellen (1) zum Rand des Trägers (2), wobei zur Kontaktierung beispielsweise eine Leiterplatte mit aufgedruckten Leiterbahnen verwendet werden kann, über band- oder stegförmige Seitenteile (3) und Lautsprecher (4) zum Gerät (6), wobei sie hier in die Zuleitung (5) zwischen Lautsprecher und Kleingerät integriert werden kann. Fig. 1 shows a power supply generator for a radio or cassette device ( 6 ) with headphone playback. The solar cells ( 1 ) are mounted on a curved band-shaped carrier ( 2 ), which is preferably made of unbreakable plastic; 2 webs ( 3 ) are attached to each of the two sides of the carrier, on which speakers ( 4 ) are attached. A translucent protective layer is applied to the solar cells, which consists, for example, of a plastic film or a translucent synthetic resin. The power supply of the battery in the device ( 6 ) takes place, starting from supply lines on the top and bottom of the solar cells ( 1 ) to the edge of the carrier ( 2 ), whereby for contacting, for example, a printed circuit board with printed conductor tracks can be used via tape or Web-shaped side parts ( 3 ) and loudspeakers ( 4 ) to the device ( 6 ), whereby they can be integrated into the feed line ( 5 ) between the loudspeaker and the small device.
Im Ausführungsbeispiel sind 8 Solarzellen hintereinandergeschaltet, so daß sich eine Versorgungsspannung von ca. 3,5 V ergibt, die für den Betrieb von Kas setten- und Rundfunkgeräten ausreichend ist. Die Zahl und die Größe der Solarzellen kann den jeweiligen Bedürfnissen angepaßt werden.In the exemplary embodiment, 8 solar cells are connected in series, so that a supply voltage of approx. 3.5 V, which is necessary for the operation of Kas set and radio equipment is sufficient. The number and size of the Solar cells can be adapted to the respective needs.
Fig. 2 stellt einen Stromversorgungsgenerator für einen elektrisch heizbaren Ohrwärmer dar. Die Solarzellen (1) sind ebenfalls wie in Fig. 1 auf einem gebogenen Träger (2 a) angebracht, wobei hier allerdings mehrere Reihen hinter einander- und/oder parallelgeschalteter Solarzellen vorgesehen werden können. Über Zuleitungen wird auch hier der Strom von den Kontakten der Solarzelle zum Rand des Trägers und von dort über Verbindungsstege (3) zum Ohrwärmer (8) mit eingebautem Heizelement und Akku geführt. Fig. 2 shows a power supply generator for an electrically heatable ear warmer. The solar cells ( 1 ) are also mounted as in Fig. 1 on a curved support ( 2 a ), but here several rows are provided one behind the other and / or parallel connected solar cells can. Here, too, the current is led from the contacts of the solar cell to the edge of the carrier and from there via connecting webs ( 3 ) to the ear warmer ( 8 ) with built-in heating element and battery.
Im Ausführungsbeispiel sind 3 Reihen von jeweils 6 hintereinandergeschalteten Solarzellen parallel geschaltet. Durch Verwendung des Akkus kann die Heizung auch bei fehlender Lichtquelle (Dunkelheit) betrieben werden.In the exemplary embodiment, 3 rows of 6 are connected in series Solar cells connected in parallel. By using the battery, the heater can can also be operated when there is no light source (darkness).
Außerdem ist der Einsatz des erfindungsgemäßen Solargenerators bei Fern steuerungen von Modellflugzeugen, Modellschiffen, Modellautos o.ä. vorgesehen, bei denen der Bügel (7) in die Kopfbedeckung integriert werden kann bzw. als Kopfbedeckung ausgebildet ist.In addition, the use of the solar generator according to the invention in remote controls of model aircraft, model ships, model cars or the like. provided, in which the bracket ( 7 ) can be integrated into the headgear or is designed as a headgear.
