Many car headlights now use LED lights. Although these lights look good, there are also some problems. Due to the lower temperature of LEDs, in fact, the difficulty of material selection and design mentioned above is reduced to a corresponding extent. However, low temperatures bring another problem: fogging.
There is generally high humidity inside the lamp body. Generally speaking, there are three sources of water vapor: polymer components generally absorb water from the environment and release it again when the external environment changes; water vapor from the external environment penetrates into the lamp body through the shell; external water vapor Enter the interior of the lamp body through the car lamp ventilation hole. It is actually very simple to solve the problem of fogging. You only need to install a layer of waterproof and breathable membrane for car lights and the problem can be solved easily.
Waterproof and breathable membrane for car lights It is hydrophobic, breathable and dustproof. The pore diameter is 0.1-1 micron, which is 10,000 times smaller than water beads, making it impossible for moisture to pass through. It protects components well, avoids liquid erosion, and increases product service life. The micropores are 700 times larger than water vapor, which prevents water from entering while allowing air to pass smoothly, which can dissipate heat well and prevent fogging inside the product. The protection level can reach IP68.
The waterproof and breathable membrane for car lights produced uses imported raw materials with good molecular weight, high cleanliness and good uniformity. At the same time, it provides professional ideas, technology, and equipment to jointly develop with cooperative customers to provide targeted solutions; a complete logistics and distribution system, guaranteed delivery, professional technical equipment, and an independent composite workshop ensure the quality of the membrane and allow customers to buy of peace of mind. Interested parties can enter the store for consultation.
