Light Diffuser film also known as led diffuser sheet is an optical material primarily used to homogenize and scatter light.
Diffuser films are widely applied in various optical systems and display and lighting technologies, such as liquid crystal displays (LCDs), LED lighting, backlight modules, and optical sensors. Here are some key features and applications of diffuser films:
The main function of led light diffuser film is to reduce light transmission by scattering the light, thereby producing an even light distribution. These films are typically made of transparent PET or PC materials with microstructures or diffuser coating layer. As light passes through the light diffuser film, it gets scattered by these microstructures or coating particles, resulting in a uniform light distribution on the exit surface.
Key Features of LED light diffuser film
1.Light Transmission Rates: The Light Transmission rates of a light diffuser film can be designed according to requirements to meet different applications' demands for light uniformity.
2.Material Selection: Common materials include PET and Polycarbonate (PC). These materials can be chosen based on the application's environmental needs, such as UV resistance and high-temperature resistance.
Applications of LED light diffuser film
1. Display Technology: In LCD and OLED displays, light diffuser films are used in backlight modules to distribute the light source evenly, ensuring uniform screen brightness and enhancing display quality.
2. LED Lighting: In LED lighting fixtures, light diffuser films can reduce glare and provide a soft lighting effect.
3. Photography and Imaging Technology: Light diffuser films are used in optical sensors and photographic equipment to evenly illuminate the subject, improving image quality.
4. Automotive Lighting: Light diffuser films are applied in automotive headlights and taillights to provide uniform light distribution, enhancing safety.
1. Improved Light Efficiency: By evenly distributing light, light diffuser films enhance the effective use of the light source.
2. Reduced Glare (UGR): Diffuse the light reduces glare issues caused by direct light.
3. Enhanced Visual Effects: In display and lighting applications, light diffuser sheet can uniform light distribution improves visual effects for led display applications and led lighting fixtures.
