Spring lighting device belongs to the field of technique of mobile devices, for lightening with mechanical drive of generator for electrical lighting. Technical problem of already known solutions, state-of-art of these devices is a heavy weight of driving engines, and therefore is inappropriate for use, i.e. carrying the devices. The subject matter of the invention is in that, that a beam of manually wound rubber strips makes a spring motor, for driving of electric generator for illumination, and the rubber is of small specific weight and therefore this spring lighting device is appropriate for use. |
