[0002] Street lamps are lamps that provide road lighting, and are divided into sodium lamp street lamps, LED street lamps, energy-saving street lamps, etc. according to the light source. Among them, LED street lamps are widely used in response to energy conservation and emission reduction requirements. LED light-emitting elements are prone to generate high heat during the power emission process, and when working in a continuous high temperature environment, poor heat dissipation can easily cause lamp damage and serious light decay, so a radiator is needed.

[0003] For example, the application number is CN202223350185.8. The utility model provides a heat dissipation structure of a street lamp, including a lampshade upper cover, a plurality of air inlet holes are respectively provided on both sides of the lampshade upper cover, the bottom of the lampshade upper cover is connected to the lampshade lower cover by screw threads, a plurality of heat dissipation holes are distributed on the surface of the lampshade lower cover, two lamp holes are provided in the middle of the surface of the lampshade lower cover, a power supply hole is provided on one side of the surface of the lampshade lower cover, a lamp holder is fixedly installed on the top of the lampshade lower cover, a threaded hole is provided on the inner bottom of the lamp holder, a lamp bead is threadedly connected to the inner bottom of the lamp holder through the threaded hole, and a condenser is fixedly installed on the bottom. The utility model: through the air inlet holes provided, convection wind directions at multiple angles can be blown in from the outside of the lampshade, and natural wind circulation is used to dissipate the heat of the lamp body, a plurality of heat dissipation holes are distributed on the surface of the lampshade lower cover, and the wind blown in by convection can be circulated out from the heat dissipation holes, and natural wind circulation heat dissipation can effectively reduce the power loss of the street lamp.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the radiator module itself will generate heat energy to heat the lamp body, rather than having a unidirectional heat dissipation effect, and the heat dissipation holes of the street lamp are arranged above and below the lamp body, and cannot receive the convection wind direction. The airflow in the lamp body does not circulate, which reduces the heat dissipation effect of the lamp body. In addition, the lamp beads of the street lamp are exposed, and the light source dissipates outdoors, and it cannot illuminate and focus the designated area, making the vision of the people blurred when passing by this kind of street lamp. Therefore, the heat dissipation and practicality of the street lamp still need to be improved.

When the user needs to place the protective cover 5 on the top of the bottom plate 3, the user first aligns the guide block 111 at the bottom of the protective cover 5 with the guide groove 112, and then moves the protective cover 5 downward to make the guide block 111 completely move into the guide groove 112. The guide groove 112 can be used to limit the moving direction of the guide block 111, thereby facilitating the user to install the protective cover 5. When the guide block 111 is completely moved into the guide groove 112, the reinforcement groove 12 of the guide block 111 is connected to the reinforcement groove 12 on the bottom plate 3. The user aligns the reinforcement rod 13 with the reinforcement rod 13 and rotates the reinforcement rod 13 to make the reinforcement rod 13 completely move into the reinforcement groove 12. 13 is connected to the reinforcement groove 12, so that the guide block 111 cannot move out of the guide groove 112, thereby connecting the protective cover 5 to the bottom plate 3. When the user needs to install the protective plate 15, first align the connecting block 16 on the inner side of the mounting plate with the top of the mounting groove 18, and then move the protective plate 15 downward to move the connecting block 16 to the bottom of the inner wall of the mounting groove 18. The mounting groove 18 can be used to limit the moving direction of the connecting block 16, so that the protective plate 15 can be installed on both sides of the protective cover 5. The protective plate 15 can be used to block a large amount of rainwater from entering the interior of the protective cover 5. When the user moves the connecting block 16 completely to the interior of the mounting groove 18, align the auxiliary block 19 at the bottom of the limiting plate 20 with the auxiliary block 19 at the bottom of the limiting plate 20. The mounting groove 18 is installed, and the limit plate 20 is moved downward so that the auxiliary block 19 is completely moved into the inside of the mounting groove 18. At this time, the limit groove 21 on the limit plate 20 is connected with the limit groove 21 on the top of the mounting block 17. Then the limit rod 22 is aligned with the limit groove 21, and the limit rod 22 is rotated to make the limit rod 22 completely move into the inside of the limit groove 21, so that the limit plate 20 is fixedly connected to the mounting block 17. The limit plate 20 can be used to prevent the connecting block 16 from moving out of the limit groove 21, thereby preventing the protective plate 15 from detaching from the protective cover 5. When the user needs to lift the protective cover 5, the protective plate 15 can be directly used to conveniently lift the protective cover 5, thereby achieving the effect of auxiliary cooling.

[0037] To sum up: the heat dissipation structure of the LED street lamp can be equipped with a cooling block 8 and a heat exhaust fan 9. The cooling block 8 can be used to facilitate the user to install the heat exhaust fan 9 inside the protective cover 5, and then the hot air inside the protective cover 5 can be discharged from the protective cover 5 through the wind slot 6 by the exhaust fan. Although the street lamp can use natural wind to reduce the temperature inside the protective cover 5, if it encounters hot and windless weather, the heat inside the protective cover 5 cannot be discharged in time. If it is in a high temperature state for a long time, it will affect the use of the street lamp.
