An intelligent light-supplementing LED system for message signs and traffic lights includes multiple optical lenses and LED units which are respectively provided behind each of the optical lens. The LED units include at least two LEDs connected in parallel; multiple LED units are connected in parallel to form a parallel system unit, or multiple LED units are connected in series to form a serial system unit. The parallel system unit is connected to a constant current power supply or a constant current circuit. The serial system unit is connected to a constant current power supply, a constant-voltage DC source, or a constant current circuit. So if an LED fails to light up, the total current that passes through the LED unit will have no or little change.
