Waterproof membrane for car lights, especially waterproof and breathable membrane, plays an important role. This membrane material can effectively prevent external moisture, dust and other contaminants from entering the interior of the lamp. As the interior of the lamp contains complex circuits, electrical components and precision optical components, these components are very sensitive to moisture and dust and other pollutants, once contaminated, it may lead to a decline in lamp performance, or even cause failure.
Waterproof and dustproof protection
The waterproof and breathable film for car lights is made of polymer membrane material, which has excellent waterproof and dustproof performance. It can effectively prevent external pollutants such as moisture, dust, oil and other contaminants from entering the interior of the lamp, thus protecting the internal circuitry, electrical components and optical components of the lamp from damage.
Reduce fogging and condensation
Reducing fogging: The waterproof breathable film allows a certain degree of air exchange between the inside and outside of the headlight, which helps to reduce the temperature and humidity difference inside the headlight, thus reducing the risk of fogging. Fogging is a common problem with headlamps, especially in environments with high humidity or temperature variations, and it can affect the lighting performance and safety of headlamps. By using a waterproof breathable film, the level of fogging inside the headlamp can be significantly reduced by up to 50%.
Condensation: Breathable waterproof film can also help to solve the problem of condensation inside the headlamps. Condensation is caused by water vapour condensing into water droplets as the temperature inside the headlamp drops. The waterproof breathable membrane allows water vapour to flow freely under balanced internal and external pressure, thus avoiding the formation of condensation droplets.
Pressure balance and exhaust function
Pressure balance: the waterproof breathable membrane has a unique exhaust function, which can exchange gas with the change of pressure inside the lamp. When the external temperature suddenly drops or the internal temperature of the lamp rises, the waterproof breathable film can quickly balance the internal and external pressure, to prevent damage to the lamp due to uneven pressure.
Venting Function: The venting function of the waterproof breathable film also helps to remove heat and moisture from inside the headlight, keeping the interior of the headlight dry and clean. This helps to extend the service life of the lamp and improve the lighting effect.
Reduce Costs and Improve Productivity
Simplified design: waterproof breathable film has a universal installation method, which can reduce the complexity of product design. Designers do not need to design a complex waterproof structure for the lights, just choose the right waterproof breathable film and install it correctly.
Reduced Costs: The use of waterproof breathable membranes can also reduce manufacturing costs. Due to the excellent performance and reliable quality of waterproof and breathable membranes, the cost of sealing design, the amount of housing material and the use of tools can be reduced. In addition, waterproof breathable membrane can also be used with sealants and adhesives to achieve on-site curing, thereby reducing assembly time and improving productivity.
V. Wide range of applications
Waterproof and breathable films for car lights are not only suitable for exterior lighting such as headlights, taillights, fog lights and auxiliary lights, but are also widely used in other fields, such as bicycle batteries, distribution boxes, motors, security equipment and automotive water pumps, etc. These fields also require waterproof, dustproof and breathable films. These areas also require waterproof, dustproof and breathable solutions to protect the equipment and extend its life.
