[0022] The present invention will be further described below with reference to the embodiments.
[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0024] Please see Figure 1-6 This utility model provides a solar LED street light with heat dissipation function, including a T-shaped support tube 1, a solar panel 2 disposed at the top of the T-shaped support tube 1, a lamp cover 3 fixedly connected to the right end of the T-shaped support tube 1, an LED light 4 fixedly installed on the lower surface inside the lamp cover 3, and a heat dissipation assembly disposed on the top of the LED light 4. The heat dissipation assembly includes a sealing cover 401, a heat-conducting copper block 402, an air duct 403, a sealing ring 404, a temperature sensor 405, an air inlet 406, a rainproof louver 407, a ventilation hole 408, and a fan 409. The sealing cover 401 is fixedly installed on the outside of the LED light 4 and located on the lamp cover. Inside the lampshade 3, a heat-conducting copper block 402 is fixedly installed on the top of the LED light 4 and passes through the top of the sealing cover 401. An air duct 403 is opened on the top of the heat-conducting copper block 402. A sealing ring 404 is fixedly installed on the outside of the heat-conducting copper block 402 and is located on the top of the sealing cover 401. A temperature sensor 405 is fixedly installed on the upper surface inside the lampshade 3. An air inlet 406 is opened at the right end of the lampshade 3. A rainproof louver 407 is rotatably installed inside the air inlet 406. A ventilation hole 408 is opened at the left end of the lampshade 3. A fan 409 is fixedly installed at the right end of the T-shaped support tube 1 and is located inside the ventilation hole 408.
[0025] Temperature sensor 405 is existing technology, capable of real-time monitoring of the temperature inside lampshade 3 and controlling the start and stop of fan 409. The installation of rain-proof louvers 407 can shield external rainwater, minimizing the possibility of rainwater seeping into the lampshade 3. The installation of sealing ring 404 can seal the connection between sealing cover 401 and heat-conducting copper block 402. The installation of fan 409 can accelerate air circulation and improve the air heat exchange rate. The heat dissipation component is designed so that the heat-conducting copper block 402 absorbs the heat generated by LED light 4 during prolonged operation and dissipates heat by increasing the contact surface with air. However, when the heat-conducting copper block 402... When the temperature of the copper block 402 is high, it will be detected by the temperature sensor 405, which will then automatically activate the fan 409. The fan 409 will then drive the hot air inside the lamp cover 3 through the ventilation hole 408 into the T-shaped support tube 1 and out. Meanwhile, external cold air will enter the sealing cover 401 through the air inlet 406 and circulate through the air duct 403. During its circulation in the air duct 403, the cold air will exchange heat with the heat-conducting copper block 402, thereby cooling the copper block 402. The heat-conducting copper block 402 will then absorb the heat generated by the LED lamp 4. This cycle continues, achieving heat dissipation and cooling of the LED lamp 4. This invention, through the design of the heat dissipation component, can actively detect and dissipate the temperature generated by the LED lamp 4, thereby effectively improving the safety of the LED lamp 4, extending its service life, and further reducing operating costs.
[0026] Specifically, such as Figure 5 and Figure 6 As shown, an adjustment groove 5 is provided on the left inner wall inside the lampshade 3. An adjustment assembly is provided inside the adjustment groove 5. The adjustment assembly includes a rotating shaft 501, a triangular block 502, a miniature electric push rod 503, a push rod 504, and a connecting rod 505. The rotating shaft 501 is rotatably connected inside the adjustment groove 5 and is fixedly connected to the rainproof louver 407. The triangular block 502 is fixedly connected to the side surface of the rotating shaft 501.
[0027] The miniature electric push rod 503 is fixedly installed on the lower surface inside the adjustment groove 5. The push rod 504 is fixedly connected to the telescopic end of the miniature electric push rod 503. The connecting rod 505 is fixedly connected to the side of the push rod 504 near the triangular block 502. The side of the connecting rod 505 away from the push rod 504 is movably engaged with one end of the triangular block 502.
[0028] The adjustment component is set up so that by activating the micro electric push rod 503, the telescopic end of the micro electric push rod 503 drives the push rod 504 to move up and down. During the up and down movement of the push rod 504, the connecting rod 505 is simultaneously driven to move up and down. Since the connecting rod 505 is movably engaged with one end of the triangular block 502, it can drive the triangular block 502 to rotate. During the rotation of the triangular block 502, it can drive the rainproof louver 407 to rotate through the rotating shaft 501, thus facilitating the adjustment of the opening gap of the rainproof louver 407 by the staff.
[0029] This invention, through the adjustment of the components, enables the device to automatically adjust the size of the opening gap of the rainproof louver 407. This not only increases the airflow volume inside the air inlet 406 but also reduces it, thus blocking external rainwater and preventing it from entering the lampshade 3, effectively improving the practicality of the device.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, a support rod 6 is fixedly connected to the top of the T-shaped support tube 1, and the top of the support rod 6 is fixedly connected to the solar panel 2. A protective door 7 is hinged to the side surface of the bottom of the T-shaped support tube 1, and an exhaust hole 8 is opened on the inner wall of the protective door 7.
[0031] The installation of the protective door 7 makes it convenient for staff to adjust and operate the device, while the opening of the exhaust port 8 facilitates the discharge of air flowing inside the T-shaped support pipe 1.
[0032] The bottom end of the T-shaped support tube 1 is fixedly installed with a base 9 by bolts. A humidity sensor 10 is fixedly installed on the upper surface inside the lampshade 3. The humidity sensor 10 is located to the left of the temperature sensor 405.
[0033] The humidity sensor 10 is existing technology and can monitor the humidity inside the lampshade 3, thereby controlling the adjustment of the rainproof louvers 407.
[0034] Specifically, such as Figure 1 As shown, the rainproof louver 407 is rhomboid in shape and is located inside the air inlet 406 with parallel vertical distribution. The ventilation hole 408 is connected to the internal channel of the T-shaped support tube 1. Water leakage holes are provided on the lower surface inside the lamp cover 3 and on both sides of the sealing cover 401.
[0035] The drainage holes facilitate the removal of water accumulated inside the lampshade 3, improving the dryness inside the lampshade 3 and extending its service life.
[0036] Working principle and usage process of this utility model:
[0037] When using this utility model, the workers first install the T-shaped support tube 1 on the top of the foundation 9 with bolts, and then install the solar panel 2, lamp cover 3 and LED light 4 respectively, and make sure that the LED light 4 can work normally.
[0038] During the operation of LED lamp 4, the heat-conducting copper block 402 absorbs the heat generated by LED lamp 4 during long-term operation and dissipates heat by increasing the contact surface with air. However, when the temperature of the heat-conducting copper block 402 is high, it will be sensed by the temperature sensor 405, and then the fan 409 will be automatically activated. The fan 409 will drive the hot air inside the lamp cover 3 through the ventilation hole 408 to the T-shaped support tube 1 and then exhaust it. Meanwhile, the cold air outside will enter the sealing cover 401 through the air inlet 406 and circulate through the air duct 403. During the circulation of the cold air in the air duct 403, it will exchange heat with the heat-conducting copper block 402, thereby cooling the heat-conducting copper block 402. Then, the heat-conducting copper block 402 will absorb the heat generated by LED lamp 4. This cycle is repeated to achieve heat dissipation and cooling of LED lamp 4.
[0039] Furthermore, the humidity sensor 10 monitors the humidity inside the lampshade 3 in real time. When the humidity is detected to be too high, the micro electric push rod 503 will be automatically activated, causing the telescopic end of the micro electric push rod 503 to drive the push rod 504 to move upward. During the upward movement of the push rod 504, the connecting rod 505 will move upward simultaneously. Since the connecting rod 505 is movably engaged with one end of the triangular block 502, it can drive the triangular block 502 to rotate. During the rotation of the triangular block 502, it can drive the rainproof louvers 407 to rotate through the rotating shaft 501, thereby reducing the gap between the rainproof louvers 407 and blocking external rainwater.
