[0002] With the rapid development of road traffic construction in my country, the construction scale and number of highway tunnels are increasing. Tunnel lighting faces challenges such as energy saving and safety. The maturity of LED light source technology has prompted the lighting industry to widely apply LED technology in highway tunnel lighting to meet the needs of high light efficiency, good stability and long life. LED generates heat when working, which is a natural phenomenon in the process of converting electrical energy into light energy. If this heat cannot be effectively removed from the LED chip, it will cause the temperature of the LED to rise. The brightness and life of the LED are closely related to its operating temperature. If the temperature of the LED is too high, its performance will decrease, the brightness and color consistency will be affected, and the life will be shortened. In the prior art, large aluminum profile LED lamps used in tunnels generally use heat dissipation fins to improve the heat dissipation effect.
