LED quick activation system

A light-emitting diode (LED) quick activation system, comprising:

• a driving circuit, configured to generate a driving voltage and a driving current using a received power;
• a loading module, electrically coupled to the driving circuit, and configured to illuminate its LED unit using the driving voltage and the driving current;
• a filter capacitor, electrically coupled to the loading module in parallel, and configured to charge its cross voltage using the driving voltage or discharge its cross voltage to ground;
• a current control switch, electrically coupled to the driving circuit for receiving the driving circuit, and configured to control input power to the loading module and the filter capacitor;
• a quick discharging module, electrically coupled to the loading module and the filter capacitor in parallel, and configured to aid in the filter capacitor's discharging to a ground level;
• and
• a primary controller, electrically coupled to the driving circuit, the current control switch and the quick discharging module, configured to record a preceding discharging parameter that the filter capacitor requires to discharge its cross voltage from a target charging voltage to the loading module's LED unit's barrier voltage, configured to calculate an equivalent charging period of charging the filter capacitor's cross voltage to the target charging voltage using the discharging parameter, configured to control the current control switch to charge the filter capacitor and the loading module using the driving current of a charging amplitude during the equivalent charging period, and configured to charge the filter capacitor and the loading module using the driving current of a regular amplitude after the equivalent charging period passes;
• wherein the target charging voltage refers to a lower-bound voltage that successfully drives the loading module.
