There are many types of car lamps. Including headlights, fog lights, tail lights, signal lights, indicator lights, turn signals, etc. For headlights, fogging is often encountered in rainy or high-humidity environments, so the mist needs to be quickly dissipated. Some headlights use a structure that directly communicates with the atmosphere. The negative pressure caused when the lights are off will bring The external moisture, which makes the fogging scene more serious, and will cause damage to the internal components of the lamp. With a back film and a high breathable breathable cap, it solves the problem of fogging the car headlights. At the same time as the mist is dissipated, it can provide excellent protection during the operation of the headlights and prevent the intrusion of external moisture and dust. The headlights of cars equipped with protection products have excellent luminous performance and run smoothly for a long time even under extremely bad road conditions. For fog lights, tail lights, signal lights, indicator lights, turn lights and other lamps, although the power of light-emitting components is not as large as that of headlights, the space is relatively small, so it also requires protective products with better air permeability and high protection performance . Applicable products are tailored for a variety of car lights, which solves the protection problems of various lights, improves the reliability of car lights, extends the life of car lights, and shortens the design. And assembly time. The oleophobic film can also help car lights block pollution from gasoline, diesel, hydraulic oil and lubricants.
