How To Choose The Appropriate Uniform Light Sheet

Uniform light sheet is an optical component that can evenly distribute the light emitted by a light source, avoiding local over brightness or over darkness, and has a wide range of applications in different scenarios. Choosing a suitable uniform light plate can be considered from the following dimensions:

Clearly define the application scenario
Different application scenarios have different requirements for uniform light films, and the selection needs to be based on the specific scenario:

In the field of display screens: In digital displays such as electronic clocks, home appliance panels, and ordinary display devices, LED digital screen films can be paired with uniform light sheets, such as the 888 model uniform light sheet. After precise calculation, it can achieve excellent uniformity while ensuring brightness. The material is usually high transmittance PET, which is durable and can protect internal circuits. The uniform light film paired with the display film has obvious advantages in strong light environments, which can improve the quality of the image. The surface has been specially treated and has functions such as scratch resistance and fingerprint resistance. The size can be customized.
In the field of lighting: In high demand lighting places such as large indoor venues, stage performances, cinemas, etc., laser light uniform plates are a good choice. They have the advantages of high efficiency, long lifespan, and high stability, and can convert laser beams into uniform light spots, providing high-quality lighting effects.
In the field of optical experiments: If used in optical experiments, it is necessary to consider the compatibility of the uniform light plate with other optical components, as well as the specific requirements for light uniformity and stability in the experiment. For example, the glass uniform light plate EXG needs to be selected according to its characteristics of different diffusion half angles (0.75 ° to 9 °).

Pay attention to optical parameters
Uniformity of light: This is one of the most important parameters of a uniform light sheet. The better the uniformity, the more evenly the distribution of light, and the more it can avoid situations where the light is too bright or too dark locally. For example, the 888 model LED digital screen uniform light plate and laser light uniform light plate have been optimized and designed to achieve excellent uniform light distribution.
Light intensity and color: Choose a uniform sheet with appropriate light intensity and color according to actual needs. In lighting scenes, different places have different requirements for light intensity and color. For example, stage performances may require rich light colors and strong light intensity, while ordinary indoor lighting focuses more on soft light and appropriate light intensity.
Transmittance: A higher transmittance ensures that more light passes through the uniform plate, improving the utilization of light energy. In terms of material, uniform light sheets made of PET material usually have good transparency and can meet the needs of most scenes.

Consider material properties
Durability: Choosing durable materials can extend the service life of the uniformity sheet and reduce replacement costs. The PET material commonly used for LED digital screen film, display film, and uniform light film is not only durable, but also effectively protects the internal circuit from external environmental influences.
Weatherability and anti-aging performance: The uniform plate used in outdoor and other harsh environments needs to have good weatherability and anti-aging performance to ensure long-term stability. For example, some uniform light films used for outdoor display screens can withstand tests such as wind, sun, high temperature, and low temperature.
Flexibility: For some application scenarios that require bending or fitting, the flexibility of the uniform light sheet is important. Uniformity sheets made of PET material usually have good flexibility and can meet some special installation requirements.
 

Other factors
Size specifications: Select the appropriate size and specifications of the homogenizer according to the specific equipment and installation space. The size of the display film can be customized according to requirements, with common specifications including 10cm × 10cm, 15cm × 15cm, etc., to meet the needs of different devices.
Customized drawing service: If the existing product specifications cannot meet the requirements, you can choose a manufacturer that provides customized drawing service to customize exclusive uniform light sheets according to your own design drawings.
Cost factor: Consider the cost of the uniform film while meeting the usage requirements. The prices of uniform films of different brands, materials, and specifications may vary, so it is advisable to compare them comprehensively and choose products with higher cost-effectiveness.
