Abstract: A LED quick activation system includes a driving circuit, a loading module, a filter capacitor, a current control switch, a quick discharging module and a primary controller. The primary controller records 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. The primary controller calculates an equivalent charging period of charging the filter capacitor's cross voltage to the target charging voltage using the discharging parameter. The primary controller controls 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. The primary controller charges the filter capacitor and the loading module using the driving current of a regular amplitude after the equivalent charging period passes.
