ENERGY CONSERVATION USING AN IMPROVED ELECTRONIC SCANNING CIRCUIT

摘要

The invention relates to the use of electronic scanning as an energy conservation tool. According to the invention, the electronic scanning is carried out using a circuit which performs a determined sequence for any device, such as a decimal counter, or using a microcontroller. Electronic devices, such as LEDs which can be replaced by other sequential electronic devices, are connected to the outlet of the circuit. In addition, the invention exploits the fact that, at a switching-on frequency of 60 Hertz, a human cannot distinguish the flicker caused by the devices switching on and off.
