Automotive lamp waterproof breathable film is a film material designed for automotive lamps, its main function is to prevent moisture and dirt from entering the interior of the lamp, while allowing gas to pass through to maintain the pressure balance between the inside and outside of the lamp and prevent fogging. The following is a detailed introduction to the waterproof breathable film for automotive lamps and lanterns:
Role
Waterproof and dustproof: waterproof and breathable film for automotive lamps and lanterns can effectively block the external moisture and dirt into the interior of the lamps and lanterns, to protect the electronic components inside the lamps and lanterns from corrosion and pollution.
Breathable balance pressure: waterproof breathable film has a microporous structure, allowing air circulation, thus maintaining the pressure balance between the inside and outside of the lamps and lanterns, preventing damage to the lamps and lanterns due to pressure difference or performance degradation.
Anti-fogging: Breathable membrane can effectively reduce the fogging phenomenon inside the luminaire, improve the lighting effect and safety of the luminaire.
Performance Parameters
Air permeability: air permeability is generally measured by the resistance coefficient, the smaller the coefficient, the better the air permeability. Commonly used lamp waterproof breathable membrane resistance coefficient range of 2 ~ 5.
Waterproof grade: waterproof grade is often expressed by the IP grade, IP grade consists of two digits, respectively, dustproof grade and waterproof grade. The waterproof grade of waterproof breathable film for headlights is generally not less than IP67, which can be used continuously for more than 30 minutes in 1 metre deep water.
Temperature range: the temperature range is one of the important parameters of the waterproof breathable film for car lamps, different car lamps work at different temperatures, so you need to choose the appropriate temperature range. Generally speaking, the temperature range of waterproof and breathable film for headlights is between -40℃ and 120℃.
Application Scenarios
Waterproof and breathable film for automotive lamps is widely used in automotive headlights, taillights, fog lamps and auxiliary lamps and other lamps. These lamps need to be exposed to the external environment for a long time, often subject to rain, snow, dust and mud, so we need to use waterproof breathable film to protect the normal work of the lamps.
