Description: A FEEDING DEVICE WITH SOLAR CELLS, WORKING WITH ARTIFICIAL LIGHT SOURCES, FOR ELECTRONIC EQUIPMENTS The present invention concerns a feeding device with solar cells, working with artificial light sources, for electronic equipments. It is known that one of the main problems of those electronic equipments that shall provide for the amplification of signals of small amplitude consists of the background noise that limits the minimum signal to be amplified. The noise may be reduced by means of an accurate planning and, even more, by deserving a great attention to the energy source, i.e. to the feeding. Usually, all feeding obtained by the distribution net of electric energy generates noise and statics, which limit the resolution of the electronic amplification equipments. The phenomenon can be immediately heard in those audio equipments in which over-refined feeding circuits are used for reducing the feeding noise, for avoiding said phenomenon. Another solution for reducing said noise consists of the use of battery feeding or accumulator, with good results but with evident inconveniences. In fact, all statics coming from the electric net are eliminated; as there are no rectification circuits, together with the noise also the band switching noise of the rectification diodes is eliminated. From the tests performed on the use of such feeding a phenomenon appears that might be linked to the electrochemical reaction time or to the used materials, and said phenomenon is clearly audible in the sound field: - small signals forming the high frequency harmonics, are not reproduced with the correct phase or are even cut; - in terms of listening, the ambience gets lost, - the phenomenon is audible in the reproduction as well as in the recording phase, and the ambience is one of the most important parameters in the sound reproduction. Therefore, it is possible to turn to generators like dynamo or alternators for obtaining an energy source that is not connected to a net nor of electrochemical nature, whereby said generators comprise moving parts, are noisy and require a constant control of their working. It is the aim of solving above mentioned problems by means of an innovating solution that exploits a current source of a considerable duration, that does not move and that does not require any control. The aim set forth is reached by means of the device according to the present invention, consisting of a structure realized with one or more solar cells, in series or parallel, until the required tension and current are obtained, and comprising a light source with led diodes lamps fed by the electric current system or by other electric sources, with the possible relative stabilization system and sending for use, and/ or - if ever possible - obviously susceptible of working with the natural sunlight. The results obtained in the electronic equipments with this kind of feeding have proved to be higher that any kind of conventional feeding system. The smaller signals may be reproduced without any kind of phase-displacement and in the correct amplitude, with a decidedly higher solution. With sound reproducing equipments, all this implies an exceptional, absolutely likely ambience reproduction, thus obtaining in a simple way results never obtained before by any known equipment. Tests have been performed with sound recording systems and a considerable improvement has been obtained by means of the feeding according to the present invention, when compared with the same equipments fed with other systems. The present invention will be explained more in detail hereinbelow relating to the enclosed drawing in which an embodiment is shown. Figure 1 shows a feeding device with solar cells, working with artificial light sources, for electronic equipments, consisting of a structure 1 preferably winding, internally covered with solar cells 2, comprising a light source 3 consisting of lamps and/ or led fed by the electric system also when there is no natural light, with a relative stabilized feeder towards user devices 5. The feeding device with solar cells, working with artificial light sources, for electronic equipments, according to the present invention may be used in recording and reproducing equipments for sound and video and in all those devices where amplifiers are used requiring a high solution, like electromedical equipments, measuring equipments, equipments for receiving radio signals, electronic telescopes and microscopes.
