ABSTRACT:
FIELD OF THE INVENTION
The invention concerns a Security and Fashion Solar Light based on a solar-driven device, thus independent of external sources of energy, which thanks to an activated luminescent layer of foil increases visibility and thus safety.
BACKGROUND OF THE INVENTION
As situations are always arising in traffic, or when catastrophes occur, or in dangerous places of work or very secluded places, where it is very important to be seen, there is a need for a device to provide light without any effort on the part of the user.
SUMMARY OF THE INVENTION
The present invention solves this problem by providing a solar light device which is activated at the onset of darkness, which self-charges with solar energy and is independent of any source of energy. The solar light device includes a luminescent layer of foil which is operated by solar cells or a solar cell laminate. At least one accumulator is providing for accumulating energy from the solar cells. Control system electronics regulates the charging and discharging process of the least one accumulator and controls operation of the luminescent foil. The luminescent foil serves to increase visibility and thus safety or visual attractiveness.
