What is LED Diffuser Sheet?

The LED diffuser sheet/diffuser plate is a physical image that refracts, reflects, and scatters when it encounters two mediums with different refractive indices during the path of light by means of chemical or physical means, through the use of substrates such as PMMA, PC, PS, and PP. The inorganic or organic light diffusing agent is added to the base, or the array of micro-features of the structure on the surface of the substrate artificially adjusts the light, and causes the light to refract, reflect, and scatter in different directions. Thereby changing the path of light and achieving sufficient incident light. Scattered colors produce optical diffusion effects. LED diffuser sheet/diffuser plate are widely used in liquid crystal displays, LED lighting, and imaging display systems.We supply Diffuser sheet for Back-lit LED Luminaire, Acrylic Diffuser Sheet with good quality.

Plastic Artist-Acrylic Processing Technology

Acrylic can be used casting, injection molding, extrusion, thermoforming, laser engraving, laser cutting and other processes. Casting molding Casting molding for forming plexiglass sheet, bar and other profiles, that is, body-bulk polymerization method of forming profiles. After casting molded products need to be post-processed, post-processing conditions are incubated at 60 ℃ 2 hours, 120 ℃ for 2 hours. Injection molding Injection molding using suspension polymerization obtained pellets, molding in the ordinary plunger or screw injection molding machine. Process parameters include screw injection molding machine, plunger injection molding machine, barrel temperature, injection molding products also need to eliminate the internal stress treatment, processing in the hot air circulation oven at 70 ~ 80 ℃, processing time as the thickness of acrylic products, the general All about 4 hours. Thermoforming Thermoforming is the process of making plexiglass sheets or she...

How much do you know about PMMA Diffuser Sheet?

Background, technical characteristics, principle and application of PMMA diffuser. High Quality PMMA Diffuser Sheet , a material with light diffusing properties, is one of the types of diffuser plates of PS (polystyrene), PC (polycarbonate), PP (polypropylene), etc. The optical characteristics of plastic sheets such as haze, high light transmittance and high diffusivity can effectively convert point or line light sources into soft and uniform surface light sources. Under the premise of achieving good light transmittance, they also have good The light source lattice shielding property is an ideal optical material for solving the secondary light distribution of LED lamp products, and is the best light diffusion material for LED lighting products. PMMA Diffuser Sheet First, the PMMA diffuser produces a background In the process of LED lighting fixtures being gradually accepted by the market, the problem of LED lamp masks has been plagued by lamp manufacturers, which must have h...

What Effect Does The Haze Of The PS Diffuser Have On Light Transmission?

The haze of the PS diffuser has a certain influence on the light transmittance of the material. What kind of influence is there, and what is the haze? Let   China Acrylic Sheet Factory   analyze it for everyone. Haze, also known as turbidity, can be used to measure the extent to which a transparent or translucent material is unclear or turbid, and represents an indicator of scatter. Haze is caused by a cloudy or hazy appearance caused by light scattering from the internal or external surface of the material. In simple terms, haze is the percentage of the ratio of the diffuse light flux to the painful material flux. Both light transmittance and haze are important indicators for measuring the transparency of materials. The relationship between the two is as follows: Generally speaking, there is an inverse relationship between light transmittance and haze, that is, a material with a high transmittance has a low haze. vice versa. But the relationship between the two is not always ...
