Abstract:
A generator device for providing a controlled output current to a load, the device comprising:a) a panel for generating electric current from light;b) a capacitor connected to the output of said panel;c) output terminals receiving power from said capacitor for connection to a load;d) a generator for supplying electric current to said output terminals and to said capacitor;e) a source of stored mechanical energy;f) a gear train connected to the source of said stored mechanical energy so as to drive said generator;g) a control circuit for controlling supply of electrical current to said output terminals from said panel, said capacitor and said generator, the control circuit comprising:h) a transistor switch arrangement for enabling said generator and said panel to charge said capacitor and for shorting the connection between the generator and said output terminals if the charged capacitor voltage exceeds a predetermined value whereby the release of mechanical energy is prevented and said capacitor is enabled to supply power to said load.
