Description

The invention relates to a power supply generator for a small device that consists of one made up of several solar cells interconnected solar generator exists.

Such a generator is in the literature "Funkschau 17", p. 44 (1985).

Radios have been on the market for a long time, Walkmen and other small devices, e.g. Calculator and Clocks, available for direct power supply Solar cell modules on the housing surface attached or with a built-in battery is reloaded, if that on the case surface attached solar cell module with sunlight or artificial light sources is irradiated.

From DE-GM 82 33 788 is on a headgear mounted radio receiver known, in whose Housing solar cells are integrated.

DE-OS 26 25 655 describes a hearing aid arranged in a temple for the solar cells are.

From DE-OS 36 07 885 is already an intercom known in the light-emitting and light-receiving Facilities on one worn on the head Stirrups are arranged; the power supply  is done by means of batteries. Furthermore, a charging adapter is from DE-GM 81 12 568 known for solar cells, the solar cells for the Serve lighting equipment. Finally, in DE-OS 30 13 037 a terrestrial Solar cell generator described, in which the in embedded plastic cells on a plastic layer a carrier plate are arranged.

The invention has for its object a power supply generator to specify for a small device its maximum size regardless of the supply Small device can be specified flexibly, and in which ensure adequate exposure to sunlight becomes.

This is achieved according to the invention in that the Solar generator as a bracket to be carried on the head is trained.

This arrangement of the solar generator or Solar cells and by separating power supply and small device, the size of the generator will not more limited by the dimensions of the device. The solar cells are also optimally operated by the Sun irradiated (vertical radiation of the sun, shading can be avoided). Except for Operating time, the solar generator can optimally at one Light source to be aligned, and an impermissible one Both the device and the battery can heat up can be prevented.

It is advantageous to use the bracket as a band of several interconnect solar cells and to apply this to a carrier, which on the one hand the available area and on the other hand  the stability of the generator is increased.

The leads of the generator are preferably in integrated into the narrow stirrup leads.

Devices with a built-in battery without solar cells can over a charging adapter for a solar-powered device be expanded. For devices with a built-in The described solar generator can supply solar power serve as an additional power supply.

Two exemplary embodiments are shown below:

Fig. 1 shows a power supply generator for a radio or cassette device 6 with headphone playback. The solar cells 1 are in this case mounted on a curved band-shaped carrier 2 , which preferably consists of unbreakable plastic; on each of the two sides of the carrier, two webs 3 are attached, to which loudspeakers 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 battery in the device 6 is supplied with power, starting from supply lines on the top and bottom of the solar cells 1 to the edge of the carrier 2 , it being possible for contacting, for example, to use a printed circuit board with printed conductor tracks, via band-shaped or web-shaped side parts 3 and speakers 4 to the device 6 , where it can be integrated into the supply line 5 between the loudspeaker and the small device. In the exemplary embodiment, 8 solar cells are connected in series, so that there is a supply voltage of approximately 3.5 V, which is sufficient for the operation of cassette and radio devices. The number and size of the solar cells can be adapted to the respective needs.

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 , although here several rows of solar cells connected in series and / or in parallel can be provided. The current 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 rechargeable battery is also conducted via supply lines. In the exemplary embodiment, three rows of 6 solar cells connected in series are connected in parallel. By using the battery, the heater can also be operated when there is no light source (darkness).

In addition, the use of the solar generator according to the invention for remote control of model aircraft, model ships, model cars or the like. possible, in which the bracket 7 can be integrated into the headgear or is designed as a headgear.
