As the LED street light grows, the temperature inside the light will gradually increase. The heat dissipation of the LED light head is very important. If the heat cannot be dissipated in time, it will affect the service life of the lamp. In severe cases, it will lead to the LED street light damage.

The LED street light head mainly comprises a light shell, a chip, a lens, a driver and the like. Whether the LED street light work is stable, the quality is good or bad, and it is closely related to the heat dissipation of the light body itself. When the street light works, the heat is concentrated in the LED chip. As the temperature of the chip rises, the non-uniform distribution of thermal stress, the luminous efficiency of the chip and the lasing efficiency of the fluorescent powder decrease; when the temperature exceeds a certain value, the LED device fails. The rate will rise exponentially. Therefore, improving the heat dissipation performance is a prerequisite for the industrialization of high-power LED street lamps.

In view of the adverse effects of high temperature of high-power LED street lamps, the honeycomb LED street lamps independently developed by Shandong Kaich Optical & Electronic Technology Co., Ltd. have solved the heat dissipation requirements of LED street lamps. It adopts bionics design, upper and lower through holes. The honeycomb heat dissipation structure is beneficial to heat conduction, and is conducive to convection of air up and down, taking away excess heat and greatly prolonging the service life.
