Further improvement is needed, and for this purpose, an LED street lamp that is easy to dissipate heat is proposed. Summary of the invention

[0005] The main purpose of the present invention is to provide an LED street lamp that is easy to dissipate heat and can effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is: An LED street lamp that is easy to dissipate heat, comprises a base, a support rod is installed on the right part of the upper end of the base, a connecting rod is fixedly sleeved on the outer surface of the support rod, a lampshade is connected to the right end of the connecting rod, a fan is installed in the connecting rod, an LED lamp board is installed in the lampshade, a hollow plate is installed on the left inner wall of the lampshade, a plurality of through holes are opened at the right end of the hollow plate, a heat dissipation groove is opened at the right end of the hollow plate, an air intake end of the fan is connected to an air inlet pipe, an exhaust end of the fan is communicated with the hollow plate, and a cooling component is installed on the left part of the upper end of the base.

[0007] Preferably, the cooling component includes a tank body, which is installed on the base through a bracket, and the outer cylindrical surface and the upper end of the tank body are both interspersed with electric valve tubes, and a heat exchange tube is arranged in the tank body, and the heat exchange tube is spiral, and a temperature sensor is installed inside the heat exchange tube and the tank body.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1-Figure 4 As shown, an LED street lamp that is easy to dissipate heat includes a base 1, a support rod 2 is installed on the right part of the upper end of the base 1, a connecting rod 3 is fixedly sleeved on the outer surface of the support rod 2, a lampshade 4 is connected to the right end of the connecting rod 3, a fan 5 is installed in the connecting rod 3, an LED lamp board 8 is installed in the lampshade 4, a hollow plate 6 is installed on the left inner wall of the lampshade 4, a plurality of through holes 7 are opened at the right end of the hollow plate 6, a heat dissipation groove 9 is opened at the right end of the hollow plate 6, an air intake pipe 11 is connected to the air intake end of the fan 5, and an exhaust end of the fan 5 is communicated with the hollow plate 6. When in use, the power of the LED lamp board 8 is turned on, and the LED lamp board 8 is illuminated, and the power of the fan 5 is turned on. The fan 5 transports the outside air into the hollow plate 6 through the air intake pipe 11, and blows it to the heating part of the LED lamp board 8 through the through hole 7 to dissipate heat. However, when the outside air temperature is high, the air blown in by the fan 5 is difficult to effectively take away the heat of the LED lamp board 8, resulting in a significant reduction in the heat dissipation efficiency.

[0019] In order to solve the above-mentioned disadvantages, a cooling component 10 is installed on the left upper end of the base 1. The cooling component 10 is used to reduce the temperature of the air entering the lampshade 4. The cooling component 10 includes a tank body 101, which is installed on the base 1 through a bracket. The outer cylindrical surface and the upper end of the tank body 101 are both interspersed with an electric valve tube 103. A heat exchange tube 102 is arranged in the tank body 101. The heat exchange tube 102 is spiral. A temperature sensor 104 is installed inside the heat exchange tube 102 and the tank body 101. The temperature sensor 104 is used to detect the temperature of the cooling water inside the tank body 101. One end of the heat exchange tube 102 is connected to a J-shaped tube 17, and the other end of the heat exchange tube 102 is connected to a connecting tube 16. The J-shaped tube 17 extends to the upper side of the tank body 101, and the lower end of the connecting tube 16 extends to the lower side of the tank body 101. When in use, the tank body 101 is supplied with cold water through the electric valve tube 103 on the upper side, the power of the fan 5 is turned on, and the outside air enters the heat exchange tube 102 through the J-shaped tube 17. Since the heat exchange tube 102 is immersed in water, the temperature of the air can be transferred to the cold water through the heat exchange tube 102, so that the temperature of the air drops, and then enters the hollow plate 6 through the connecting tube 16 and the air intake pipe 11, and blows to the surface of the LED lamp board 8. The cooled air can effectively take away the heat on the surface of the LED lamp board 8, reduce its surface temperature, improve the heat dissipation efficiency, and increase the service life of the LED lamp board 8. When the temperature sensor 104 detects that the water temperature is high, the electric valve tube 103 on the lower side is opened to discharge the water, and then the cold water is re-transported to the tank body 101 through the electric valve tube 103 on the upper side.

[0020] In addition, since the heat exchange tube 102 is immersed in water statically, heat accumulation will occur in the water temperature around the heat exchange tube 102, affecting the heat exchange efficiency. It is necessary to drive the heat exchange tube 102 to rotate so that the heat exchange tube 102 is constantly in contact with and updated by the water flow. For this purpose, the end of the air intake pipe 11 away from the fan 5 passes through the support rod 2 and is connected to the lower end of the connecting pipe 16. The connecting pipe 16 is rotatably connected to the air intake pipe 11 through a rotating joint. The connecting pipe 16 and the J-shaped tube 17 are both movably sleeved in the tank body 101. The lower end of the tank body 101 is equipped with a motor 12. The motor 12 A worm 13 is fixedly connected to the output end, and a bearing seat 15 is movably connected to the left end of the worm 13. The bearing seat 15 is installed at the lower end of the tank body 101. The worm 13 is meshingly connected with a worm wheel 14. The worm wheel 14 is fixedly sleeved on the outer surface of the connecting pipe 16. When in use, the control motor 12 drives the worm 13 to rotate, and the worm 13 drives the worm wheel 14 to rotate. The worm wheel 14 drives the heat exchange tube 102 to rotate through the connecting pipe 16. The rotation of the heat exchange tube 102 can make its surface constantly contact and update with the water flow, avoiding heat accumulation caused by long-term immersion of the fixed surface, thereby improving the heat exchange efficiency.
