[0002] An LED street lamp refers to a street lamp made of an LED light source, which has unique advantages such as high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, and high color rendering index, and is of great significance to urban lighting energy conservation. When using an LED street lamp, due to long-term use, it is prone to short-circuit or burnout. In order to avoid damage to the LED lamp caused by short-circuit or burnout, a power-off protection device is usually installed on the street lamp.
[0003] Therefore, when installing and using an LED street lamp, it is necessary to consider the installation and use of a circuit breaker. Specifically, when installing a circuit breaker, first, a maintenance door is opened at the top of the street lamp, which provides convenience for the installation and replacement of the circuit breaker through the maintenance door. However, since most street lamps are installed outdoors, when it rains, rainwater easily flows into the interior of the street lamp through the installation door, which is likely to cause damage to the interior of the street lamp. However, when the street lamp is installed in a fully sealed manner, the use of the street lamp will generate high temperature, resulting in equipment damage and then affecting the service life of the equipment. For this reason, we propose an LED street lamp with a power-off protection function. Content of the Utility Model

[0028] Please refer to Figure 4 , the waterproof baffle 18 is sleeved on the outside of the upper end of the lamp socket mounting plate 6. At the same time, the waterproof baffle 18 is sleeved on the outside of the protection plate 16. By sleeving the waterproof baffle 18 on the upper part of the lamp socket mounting plate 6, when replacing and installing the circuit breaker 13, the waterproof baffle 18 seals the upper end of the lamp socket mounting plate 6, avoiding the problem that rainwater flows into the inside of the lamp socket mounting plate 6, resulting in corrosion and damage of the internal equipment.
[0029] Working principle: When in use, it is installed on the lamp post through the lamp post connecting column 1. At the same time, the angle of the hinge 2 is adjusted, and then the lighting angle of the lamp holder mounting plate 6 can be driven to be adjusted. At the same time, a circuit breaker 13 is installed inside the upper end of the lamp holder mounting plate 6, and the position of the circuit breaker 13 is limited by the fixing plate 14 and the fastening bolts 15. When a short circuit or other conditions occur during the use of the LED lamp 8, the circuit breaker 13 can disconnect and protect the circuit. At the same time, the gas can be transmitted through the side of the lamp holder mounting plate 6 to improve the heat dissipation of the device. A protective plate 16 is installed on the side of the lamp holder mounting plate 6. The protective plate 16 improves the protection performance of the device while ensuring the gas transmission, reduces the rainwater from entering the heat dissipation holes, and reduces the damage to the internal circuit of the lamp holder mounting plate 6.
