LED street lights, tunnel lights product requires to achieve IP65 grade (waterproof, dust-proof), completely closed environment in which the gas can not be exchanged between the internal of the lamp and the external environment. When the LED lights work for a long time which lead to the pressure,temperature to increase inside the lights, to generate pressurehead between the outside air, to increase the pressure against the inwall of the lights,to accelerate the lights aging. We adopt a tailor-made respiratory system, to solve the unbalance pressure problem between the inside and the outside of the lights completely.To enhance the stability of the lamp further. The program can filter the water molecules and dust from entering the lights. Let air molecules move between the internal and external environment of the lights freely. 
1. Water and water vapor molecules contain the same atom (an oxygen atom and two hydrogen atoms). However, water molecule and water vapor molecule have very different performances, when these water molecules in a liquid state, they adsorbed with each other tightly. Thus, a single molecule can not be adsorbed to the positive and negative charges of the nano-filmon molecular chain. 
2.How is the water vapor pass through it? Water vapor molecules independent with each other, moleculars adsorb with each other. (The moving direction of the water vapor moleculars depends on the air pressure, temperature of both sides), water vapor molecules will move from the higher air pressure and temperature side to the lowwer sides.
Uses: LED lights,wash wall lights,storagre cell that need radiating.
