The utility model relates to an open circuit protection circuit of airport LED lamps and lanterns, by the airport power, overload protective device, magnetic latching relay and LED lamps and lanternsdrive power supply constitute, wherein the open circuit protection circuit between airport power and LED lamps and lanterns drive power supply. At the normal during operation of LED lamps and lanterns, the circuit passes through magnetic latching relay power supply work, when the LED lamps and lanterns are unusual, and the magnetic latching relay disconnection, the electric current flows through overload protective device, because of the current overload, cuts off whole circuit. In the unusual back of eliminating, overload protective device needs manual reset, airport LED lamps and lanterns restarting work. The advantage is: this open circuit protection circuit is applicable to all airports LED lamps and lanterns, uses magnetic latching relay, but under high temperature normal boot, electric phenomena can not appe
