[0002] LED underground pedestrian traffic light is a traffic signal auxiliary equipment embedded in the ground. It uses high-brightness LED light source and is designed for pedestrian crossing. It is mainly used in areas such as zebra crossings, squares, subway entrances, etc.

[0003] The underground traffic lights currently in use still have the following problems: 1. It is inconvenient for staff to quickly replace damaged LED lights. When staff forget to bring replacement LED lights, they cannot replace them in time; 2. There is generally a lack of auxiliary drying structure, which leads to more moisture inside the ground lamp after staff replace the new LED lamp, which easily accelerates the corrosion of the line joints and cannot guarantee the normal service life; 3. When water enters the interior of the traffic light, no automatic prompt will be issued, which is inconvenient for staff to know and affects subsequent traffic use. Summary of the Invention

The LED lamp A and the LED lamp B are automatically replaced, thereby increasing their service life while facilitating maintenance by staff. The LED lamp adsorbs moisture inside the protective underground shell A and the protective underground shell B, ensuring that the interior of the protective underground shell A and the protective underground shell B is always dry after they are connected. The LED lamp has two alarm lights, which prompt staff to replace or repair the lamp in a timely manner to avoid affecting subsequent use.

[0018] 2. The provision of two connecting blocks and two connecting control frames of the present invention makes the connection between the protective buried shell A and the protective buried shell B more secure; the provision of four support springs B serves as a limit for the two connecting control frames, so that the two connecting control frames will not move unless they are pulled;

[0019] In addition, when the protective buried shell A is connected or disassembled with the protective buried shell B, the staff needs to pull the two connection control frames; when the two connection control frames move outward, the inner ends of the two connection control frames can be separated from the two discharge slots, realizing the automatic delivery of the desiccant. The delivered desiccant automatically enters the two collection network pipes, and has an adsorption effect on the moisture inside the protective buried shell A and the protective buried shell B, so that after the protective buried shell A and the protective buried shell B are connected, the interior is always in a dry state.

[0020] 3. When the protective buried shell A and the protective buried shell B are damaged, the water entering the protective buried shell A can push the foam disc upward; when the top side of a circle of semicircular drainage grooves is higher than the inner wall of the protective buried shell A, the water inside the protective buried shell A can be discharged through the row of semicircular drainage grooves;

[0021] In addition, when the top side of a semicircular drainage trough is higher than the inner wall of the protective buried shell A, the movable installation shaft can automatically press the switch; when the switch is pressed, the two alarm lights will work, which is convenient for reminding the staff to replace or repair it in time to avoid affecting subsequent use.
