Description

A smart street lamp with high brightness and good heat dissipation

technical field

The invention belongs to the field of intelligent street lamps, in particular to an intelligent street lamp with high brightness and good heat dissipation.

Background technique

Street lamps are lamps, which are composed of electrical appliances, light sources, lamp poles, lamp arms, flanges and foundation embedded parts as a whole. The existence of street lamps makes light still exist in the dark, guiding roads and directions, and meeting people's night travel needs. Demand plays an important role in people's lives, so it has been widely used and is a common road lighting facility.

Street lamps are important objects for municipal construction and prevention of traffic accidents. Because street lamps need to work for a long time, the internal working temperature of street lamps is relatively high. Existing street lamps use metal lampposts, and the exterior is coated with paint. The surface temperature of street lamp lampshades is relatively high. , The commonly used paint has poor heat dissipation performance, so the paint on the surface of the street lamp is easy to fall off, and the bulb of the street lamp is easily damaged. In addition, the street lamp is exposed to the outdoors for a long time, and it is easy to be eroded by foreign objects, and it is easy to rust at high temperature. In addition, the surface of existing street lamps is prone to dust, which affects the lighting effect and causes energy waste.
