EASY-TO-COOL LED STREET LAMP

WIPO Patent Application WO/2023/050021

A1

An easy-to-cool LED street lamp. The LED street lamp comprises a support column (1), a heat-conducting plate (11) and a ventilation fan (8), wherein a lower end surface of the support column is fixedly connected to a fixing plate (2), an upper end surface of the support column is fixedly connected to a solar panel (3), the surface of the support column close to the solar panel is fixedly connected to a connecting column (4), a surface of the connecting column is fixedly connected to a fixing column (5), and the other end of the fixing column is fixedly connected to a surface of the support column. In the easy-to-cool the LED street lamp, by means of the arrangement of an air inlet (7), the ventilation fan, an air outlet (9), the heat-conducting plate, a dustproof filter screen (12) and a temperature sensor (13), when the LED street lamp is used, the heat-conducting plate conducts generated heat out, thereby facilitating heat dissipation; and an upper surface of the dustproof filter screen is provided with the temperature sensor, and when the temperature at the dustproof filter screen is too high, the ventilation fan is controlled to turn on by the temperature sensor, thereby accelerating air circulation, discharging heat from the air outlet, and further increasing a heat dissipation effect.
