Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and more specifically, to an LED smart street lamp based on a liftable lamp pole. Background Art

[0002] In recent years, with the acceleration of urbanization and the advancement of smart city construction, the demand for smart street lights has continued to increase. Policy support, increased market demand and technological progress have jointly promoted the market development of smart street lights. It is expected that in the next few years, the scale of the smart street light market will continue to expand and contribute more to the construction of smart cities.

[0003] Under severe weather conditions, such as strong winds and heavy rains, the components of existing smart street lights may be damaged or affect normal operation due to unstable fixation. In particular, components installed in higher positions are more susceptible to severe weather. Some smart street lights are equipped with air quality sensors to monitor the air quality of the surrounding environment. However, if the air circulation around the air quality sensor is not smooth, the gas samples detected by the sensor will be inaccurate, thus affecting the reliability of air quality monitoring. Some smart street lights integrate multiple functional components, such as display screens, base stations, and LED lamp heads. These components will generate a lot of heat when working. If the heat dissipation is poor, the temperature of the components will rise, affecting the working efficiency and life. The heat dissipation design of traditional street lights often lacks active heat dissipation structure and cannot meet the high heat dissipation requirements of smart street lights.

[0042] Working principle: The LED smart street light of the present application, as shown in the figure, during normal use, the electric lifting rod rises, so that the first, second, third, and fourth top plates respectively lift up the first, second, third, and fourth plug plates, so that the first, second, third, and fourth components are in a higher position for normal use, and at this time the first, second, third, and fourth pull ropes are in a taut state, so that the positions of the first, second, third, and fourth components are stable.
