Principles and characteristics of PMMA diffuser sheet

Light Diffuser

PMMA Diffuser Sheet, also known as (polymethyl acrylic, alias acrylic, acrylic, organic glass), is a material with light diffusion properties. ), PP (polypropylene) and other material diffusion board categories, have the optical characteristics of plastic boards such as high -fog, high light transmission, high diffusion, etc., which can effectively convert points or line light sources to soft and uniformly. The surface light source, under the premise of reaching a good light transmittance, has good light source block covering at the same time. It is the ideal optical material for solving the secondary light of LED lamp products. Essence

Principle of Acrylic Diffuser
Through chemical or physical means, the diffusion board uses light to encounter two mediums with similar refractive indexes during lines, and the physical imagination of refraction, reflection and scattering occurs. , Or the arrangers of the micro -signs on the surface of the substrate surface to adjust the light, reflect, reflect, and scatter the light in different directions to change the moving route of the light and achieve the effect of incident light to produce the effect of optical diffusion Essence

The characteristics of the Anti-Glaring Diffuser Sheet
High brightness: Under the same penetration rate, the brightness can be increased than the traditional diffuser.
Excellent shielding effect: The light source diffusion and uniformity are good, and the shielding lamp effect is excellent.
High -size stability: small water absorption and warranty, excellent size stability.
Excellent durability: In the ultraviolet aging acceleration test, it is not easy to have yellowing.
Excellent quality assurance: Light Diffuser of products have been disabled to ban poison tests in UL-94 and ROHS.
It is mainly reflected in the LED tablet lamp panel, LED down lights, grille lamps, ceiling lamp masks, and advertising light boxes, sign signs and other products.
