What is a diffuser plate? What is the difference between PC/PS/acrylic diffuser?

  How much do you know about diffuser panels? Diffuser plates come in many categories and have a wide range of uses. The following briefly introduces the three main diffusers: PC diffuser, PS diffuser and acrylic diffuser.

LED Diffuser

Diffuser plate

Diffuser principle:

By chemical or physical means, using the physical imagination of refraction, reflection and scattering when light encounters two media with different refractive indices on the way, by adding inorganic or organic light diffusing agents to raw materials, or through the substrate The array arrangement of the micro-feature structures on the surface artificially adjusts the light, so that the light is refracted, reflected, and scattered in different directions, thereby changing the light's traveling route, and realizing the sufficient dispersion of the incident light to produce the effect of optical diffusion.

PC light diffuser

PC diffuser plate, also known as diffused polycarbonate plate, also known as PC light diffuser plate, PC light diffuser plate, PC diffuse reflector plate, etc.

PC diffuser board is a product processed by a special process on the basis of ordinary PC single-layer board. It is a new optical material that realizes uniform surface lighting. The effect of PC diffuser board is good or bad. It is closely related to the content and composition of the diffuser particles. The less the content of diffusing particles, the higher the light transmittance and the lower the haze. The diffuser plate is generally light white and translucent. The more the content of diffusing particles, the lower the light transmittance and the higher the haze. , The diffuser is generally milky white and opaque, so it can be seen that the light transmittance and haze of the diffuser are inversely proportional, that is, the two cannot have both.

Appearance: Milky white board is translucent, with few crystal points and high light transmission, high smoothness and good flatness. Super impact resistance: It is 250 times stronger than ordinary glass plates, more than 150 times stronger than tempered glass, and 30 times higher than acrylic plates. So it doesn't break in the event of various accidents. Better protect your property and life. Construction performance: The density of PC is 1.2, and the weight is only 1/2 of that of glass, so the quality is lighter and easier to construct, reducing costs. Uses: LED and fluorescent lamps, panel lights, advertising light boxes as light sources, billboards, outdoor billboards, stage special effects, LED electronic displays, natural lighting ceiling lights.

PS light diffuser

PS diffuser plate is a kind of material with light diffusing properties in PS (polystyrene) sheet type. The optical characteristics of plastic sheets such as light transmittance and refractive index can effectively convert point or line light sources into soft and uniform surface light sources. On the premise of achieving good light transmittance, it also has good light source lattice shielding. . In addition, the price is relatively affordable, so it is widely used in the booming LCD-TV and LED lighting products, adding a choice of optical diffusion materials for the secondary light distribution of LED lighting products.

PS diffuser plate application

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

1. The direct-type backlight system used in LCD TVs requires PS diffusers to have good properties such as heat resistance, dimensional stability, mechanical strength, and flame resistance, as well as high light transmittance, excellent shielding and Durability, its light diffusion effect reaches the best condition, and it is suitable for direct type backlight unit.

2. The diffuser plate is used in lighting, mainly reflected in LED flat light panels, LED downlights, grille lights, ceiling light masks, advertising light boxes, sightseeing films and other products.

Acrylic diffuser

Acrylic diffuser

Acrylic diffuser has the optical characteristics of high haze, high light transmittance, high diffusivity and other plastic sheets. It can effectively convert point or line light sources into soft and uniform surface light sources, on the premise of achieving good light transmittance. , At the same time, it has good light source lattice shielding, it is an ideal optical material to solve the secondary light distribution of LED lighting products, and it is a good light diffusing material for LED lighting products.

Acrylic diffuser features

High brightness: Under the same transmittance, the brightness can be improved compared with the traditional diffuser.

Excellent shading effect: good light source diffusion and homogenization ability, excellent shading effect of lamp tube.

High dimensional stability: small amount of water absorption and warpage, excellent dimensional stability.

Excellent durability: In the accelerated UV aging test, it is not prone to yellowing.

Excellent quality assurance: All series of products have passed UL-94 and RoHS banned toxic substances test
