Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0048] In order to make the technical solutions and advantages of the utility model clearer, the embodiments of the utility model will be described in further detail in combination with the drawings.

[0049] Please refer to Figures 1-2As shown, the embodiment discloses an aviation obstacle light circuit, comprising an AC 220V input end: for accessing external AC power supply.

[0050] Primary lightning protection circuit 1 and secondary lightning protection circuit 2: connected in turn after AC 220V input end, to protect the subsequent circuit from lightning damage.

[0051] As shown, Figure 2 The primary lightning protection circuit 1 includes a gas discharge tube U24, which has three pins:

[0052] Pin 1: connected to the live wire ACL of the AC power supply,

[0053] Pin 2: connected to the neutral wire ACN of the AC power supply,

[0054] Pin 3: ground PE.

[0055] The voltage will rise instantaneously when lightning or other overvoltage events occur. The gas discharge tube U24 will conduct when the voltage exceeds its breakdown voltage, forming a low impedance path to discharge the overvoltage to the ground PE. At the same time, the voltage will also exceed the threshold of the voltage-dependent resistor R62, R63, which will rapidly reduce the resistance to further discharge the overvoltage. The bypass capacitor C54 further protects the subsequent circuit by filtering out high-frequency noise and transient voltage.

[0056] The secondary lightning protection circuit 2 includes two common-mode chokes L1, L2 connected to the live wire and neutral wire of the AC power supply, respectively, for suppressing common-mode noise and transient voltage.

[0057] The bypass capacitor C54 is connected between the live wire and neutral wire of the AC power supply, for filtering out high-frequency noise and transient voltage.

[0058] The voltage will rise instantaneously when lightning or other overvoltage events occur. The gas discharge tube U24 will conduct when the voltage exceeds its breakdown voltage, forming a low impedance path to discharge the overvoltage to the ground PE. At the same time, the voltage will also exceed the threshold of the voltage-dependent resistor R62, R63, which will rapidly reduce the resistance to further discharge the overvoltage.

The switch power supply 5 module rectifies the AC power to pulsed DC power. The pulsed DC power after rectification is subjected to high-frequency switching operation by the switching converter to achieve energy conversion. The high-frequency pulse current after switching conversion is smoothed by the filter capacitor to obtain a stable DC output.

[0061] As shown, Figure 5As shown, the 5V voltage stabilizing circuit 6 is connected after the switching power supply 5 module, ensuring that the subsequent circuit provides a stable working voltage. The input voltage 12V is preliminarily filtered by capacitors C31 and C32 to remove high-frequency noise. The U7 voltage stabilizer stabilizes the filtered 12V voltage to 5V. The EN terminal is used to control the opening and closing of the voltage stabilizer, usually connected to the ground to keep the voltage stabilizer always on. The 5V voltage stabilizing circuit 6 converts the 12V power supply to a stable 5V output through the voltage stabilizer U7, and filters through the input and output capacitors to ensure the stability and reliability of the output voltage.

[0063] As shown in Figure 3 The LED drive control circuit 8 is connected to the energy storage circuit 7 and the MCU 10, and adjusts the brightness and working state of the LED light source module according to the control signal. DT-BT1 is connected to the 48V power supply of the energy storage circuit 7, and multiple resistors are used for voltage division, current limiting, and adjustment.

The LED driving control circuit 8 ensures the high stability and reliability of the output voltage through multi-stage voltage regulator, filter capacitor and protection components.

[0071] The LED light source module is composed of multiple high-efficiency energy-saving LEDs, which is connected to the LED driving control circuit 8 and emits light signals with specified light intensity.

[0072] As shown in Figure 4 , the MCU 10 serves as the core controller of the entire circuit, receives signals from different sensors and communication modules, and issues control instructions accordingly.

[0073] As shown in Figure 5 , the ambient light sensing circuit 12 is connected to the MCU 10, detects the ambient light intensity, and feeds back information to the MCU 10 control center to automatically adjust the brightness of the LED light source module. The Beidou synchronous positioning circuit 13 is also connected to the MCU 10, providing accurate time synchronization signals to ensure that the LED light source module works according to the preset schedule.

The carrier remote communication circuit 11 is connected through the output end of the two-stage lightning protection circuit and communicates with the remote control module. The LED light source state monitoring circuit 9 is connected to the LED light source module, monitors its running state and sends feedback information to the MCU 10 control center. The LED driving control circuit 8 uses PWM dimming technology to control the average brightness of the LED by changing the pulse width, thereby realizing stepless dimming.

[0074] As shown in Figure 5 , an automatic fault alarm circuit is also provided. Once an abnormality is detected, the alarm mechanism is triggered immediately and the maintenance personnel is notified through the remote communication module, greatly shortening the fault handling time.
