Description

Technical Field

[0001] The invention belongs to the technical field of LED street lamps, and in particular relates to a solar LED street lamp that is easy to dissipate heat. Background Art

[0002] LED solar street lights use solar radiation as energy. During the day, solar panels are used to convert solar energy to charge batteries. At night, the batteries power LED light sources for lighting. There is no need to lay complex and expensive pipelines, and the layout of lamps can be adjusted at will. They are safe, energy-saving and pollution-free. They do not require manual operation and are stable and reliable, saving electricity and requiring maintenance. LED street lights will generate more heat due to long-term operation, which makes their own heat dissipation problem a hot research issue.

[0003] The existing solar LED street light that is easy to dissipate heat includes a base, a connecting rod, a lamp pole, a bracket, an LED lamp holder of an LED light source, a solar cell group, a wind power generation device, a battery group, a processing control device and a photosensitive sensor, wherein the solar cell group, the photosensitive sensor, the LED light source, and the battery group are electrically connected to the processing control device respectively, the wind power generation device is electrically connected to the control processing device through a driving motor, and the outer wall of the LED lamp holder is distributed with fins for heat dissipation.

[0004] Existing LED street lights achieve their own heat dissipation function through the heat dissipation fins distributed on them. This heat dissipation method has a significant limitation. The heat dissipation fins completely rely on the flow of external air to remove heat. However, the heat dissipation effect of street lights with heat dissipation fins cannot be guaranteed under windless conditions, resulting in heat accumulation inside them, thereby reducing the heat dissipation efficiency of the heat dissipation fins. This situation will seriously affect the normal heat dissipation function of the street lights, and then cause the LED street lights to overheat, affecting their performance and lifespan.

[0005] Therefore, in view of the above situation, it is urgent to develop a solar LED street light that is easy to dissipate heat to overcome the shortcomings in current practical applications. Summary of the invention

[0058] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0059] like Figures 1 to 8 As shown, a solar LED street lamp that is easy to dissipate heat provided as an embodiment of the present invention includes a lamp post 1, a lamp body module 2 and a mounting frame 3 are respectively installed at both ends of the top of the lamp post 1, the mounting frame 3 is obliquely arranged at the top of the lamp post 1 and a solar panel 4 is distributed on its upward end surface, a heat dissipation module 5 is installed on the outer wall of the top of the lamp body module 2, a control frame 8 with a shape consistent with the distribution shape of the heat dissipation module 5 is fixed on the top of the lamp body module 2, and the control frame 8 is located inside the heat dissipation module 5, and also includes:

[0060] A control component 6, one end of which is installed in the lamp body module 2, and the other end of which extends outside the lamp body module 2 and is slidably matched with a guide groove 25 opened on the top of the lamp body module 2. The opening shape of the guide groove 25 is consistent with the distribution shape of the heat dissipation module 5, and the guide groove 25 and the other end of the control component 6 are both located inside the heat dissipation module 5.

The control groove 81 preferably adopts a wavy groove body, and the vertical height of the control groove 81 is less than the vertical height of the rack 82.

[0062] In this embodiment, the battery provides a power source for the control component 6, so that one end of the control component 6 can rotate freely, and one end of the control component 6 drives the other end thereof to move along the distribution track of the guide groove 25, and the other end of the control component 6 drives the wind control component 7 to move. Under the cooperation of the control groove 81 and the rack 82, the wind control component 7 moving with the other end of the control component 6 can perform vertical reciprocating movement and self-rotation movement.

[0063] The wind control component 7 can effectively blow the air inside the heat dissipation module 5 to the outside by rotating, speeding up the flow rate of the gas around the heat dissipation module 5, and improving the heat dissipation efficiency of the heat dissipation module 5, which not only improves the heat exchange effect between the heat dissipation module 5 and the outside air, but also significantly improves the heat dissipation efficiency and heat dissipation quality of the street lamp;

[0064] The wind control component 7 under self-rotation simultaneously performs vertical reciprocating movement, so that it can drive the air outlet end to also perform vertical reciprocating movement. This can not only increase the path length of the air flow, and prolong the residence time of the air on the surface of the heat dissipation module 5, which helps to improve the heat exchange efficiency between the heat dissipation module 5 and the outside air, but also allow the outside air to enter different parts of the heat dissipation module 5, increase the contact area between the air in the flow state and the heat dissipation module 5, further improve the heat dissipation efficiency and heat dissipation quality of the heat dissipation module 5, and at the same time further improve the heat dissipation efficiency and heat dissipation quality of the street lamp, which helps to maintain the lighting intensity of the street lamp and extend the service life of the street lamp.
