The present invention refers to a circuit using the electronic scanning concept as a saving energy tooL. the electronic scanning is carried out using a PCI circuit which performs a determined sequence for any device, such as a microcontroller. The circuit also has a specific electronic devices and high-luminosity LEDS, which may be replaced by further sequence electronic devices. . 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. The illumination capability of the electronic scanning depends on the LEDS arrangement and the programmed sequence, and the device geometry. The electronic scanning is characterised in that it requires a commercial voltage (130 Volts, 220), the behavior of the current being softened by rectifying the signal so that the circuit may work at lower voltages.
