Types and application fields of diffuser

1. Types of diffuser:

    According to the classification of optical principles, there are only two types of diffusers. One is to increase the beam angle and the other is to maintain the original angle.

    According to material classification, glass, polystyrene (PS), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate ( PET), acrylic (PMMA), acrylic (MMA), etc. light-transmitting polymer or synthetic materials can be made into diffusion materials for different purposes.

    The types of diffuser can be divided into gas diffuser, sound diffuser, liquid diffuser, light diffuser, flavor diffuser, light diffuser, and all materials that can evenly disperse molecules are collectively called diffuser.

    Air diffuser --> Generally used to reduce the sound generated by the air flow, such as the muffler of a car.

    Sound diffuser --> Generally used to eliminate sound echoes caused by hard objects, such as the wall or ceiling of a concert hall.

    Liquid diffuser --> Generally used to turn liquid into mist or smaller molecules to make them evenly distributed, such as water curtains for greenhouses.

    Flavor diffuser --> Generally used to eliminate or disperse the flavor to reduce it, such as the canister of a gas mask or the deodorizing canister of a water filter.

    Light diffuser --> Generally used to prevent glare and obtain a comfortable environment for vision, such as the diffuser in front of the camera flash.

2. Application fields of diffuser:

    The light diffusion plate is widely used in liquid crystal display, LED lighting and imaging display systems. Its main function is to fully diffuse the incident light to achieve a softer and uniform illumination effect.

    A. The diffuser is applied to the liquid crystal display

    Applied to the direct-lit backlight system used in LCD TVs, the diffuser has good properties such as heat resistance, dimensional stability, mechanical strength, flame resistance, etc., and has a high light transmittance, excellent shielding and durability, so Its light diffusion effect reaches the best condition, and is most suitable for direct-lit backlight units.

 Product Features

　Light source diffusivity: suitable for direct-lit backlight modules, with high brightness and high diffusivity, which can improve the diffusion effect of the uniform light distribution of the backlight.

    Light transmittance: Excellent light transmittance produces high brightness. Dimensional stability: the water absorption rate is the smallest, it can still maintain good dimensional stability in a humid environment, and can be used normally in the temperature range of -40℃~125℃.

　Antistatic: It has good surface antistatic performance to prevent dust adsorption.

    B. Light diffuser applied to lighting

    Requirements of light diffuser for LED lighting:

    1. The best diffusion performance: high light softness;

    2. High light transmission performance: reduce energy consumption and improve the illuminance of the lamp;

    3. Impact on the light source: maintain the consistency of the color temperature of the light source.
