The LED with the advantages of energy conservation, environmental protection, long service life and the like is produced at the same time, and gradually replaces the existing high-voltage sodium lamp street lamp. The electric quantity consumed by the LED street lamp is only half of that consumed by the high-voltage sodium lamp street lamp. Obviously, LEDs have become ideal lighting sources, and the use of LEDs is also known as the fourth generation green technology light revolution of human beings

The LED street lamps in the current market are divided according to the used light sources, and can be roughly divided into COB light sources and SMD light sources. Because LED street lamp tends to miniaturization and lightweight gradually, in order to guarantee the light and heat performance of street lamp, the COB chip is applied to the street lamp gradually. The photoelectric conversion efficiency of the current COB light source is less than 30%, that is, more than 70% of electric energy is converted into heat, and the service life of the LED is inversely related to the temperature. When a plurality of LEDs are densely arranged to form a street lamp, especially when an LED light source, such as a COB, with a heat source usually concentrated within several square centimeters is used as a light source of the street lamp, if the heat source cannot be rapidly dissipated, heat inside a chip is accumulated, which causes a series of serious problems, such as light-emitting wavelength drift, accelerated aging of fluorescent powder, reduction of light-emitting efficiency, and shortened service life.

Therefore, among several key technologies determining the application of COB light source, the heat dissipation design is very important and one of the technological bottlenecks that restrict the wide use of COB light source. That is to say, the quality of the heat dissipation design directly determines the quality of the performance index of the LED street lamp using the COB light source and whether the actual popularization and application can be successful.
