Novelty: a security Led light liable to illuminate the space in case of power failure is disclosed. Constitution: the internal part having an electronic board with a ac-to-dc converter, a circuit charging the hyper-condensers, a circuit monitoring and regulating the current of the light source of the device and hyper-condensers; the external section of the plastic box where the light source is set, and the reflective light crystal whereon a phosphorescent nanotechnology membrane is placed. Compared to the widely-used security lighting elements, the combination of both technologies (use of hyper-condensers and nanotechnology) makes the present invention an innovative high-autonomy product. Advantages: autonomy exceeding the one and a half hour, with no further energy requirements; it exhibits low maintenance cost, low mains energy consumption and long service life. |
