Performance of acrylic diffusion plate
Acrylic PMMA features:
1. the color is pure and rich, the color is bright and the transmittance can reach 85% or more.
2. super strong weatherability, anti UV, anti aging, transparent plate for 30 years, color plate 10 years without yellowing.
3. super friction resistance and scratch resistance;
4. super high hardness, not broken, high safety performance
5. the material is light, and the specific gravity is only half of the glass.
6. excellent surface quality, not easy to break, can be hot formed in various shapes, easy to process.
Special optical dispersant is added to the plate made of PMMA. On the premise of ensuring high transmittance of light, the angle of the incident light is changed, and the refraction and scattering will occur when the light reaches the effective light emitting surface, so as to obtain good light diffusion effect.
Characteristics: the light transmittance reaches 85%, and the high transmittance enables the light to pass through the plate as much as possible to reach the effective light emitting surface, avoiding reflection and absorption, thus improving the light efficiency and reducing the energy consumption.
High fog: the fog reaches 99.6. high fog makes the light emitted into the plate spread more evenly, and forms a white and bright fog like turbid appearance on the effective light emitting surface.
Grinding surface: scratch proof, pollution prevention, soft hand feel, visual comfort. Whether natural light or light is used, or backlight / lighting or other lighting methods are used, it has good decorative effect.
Easy to process: it can be cut, bonded or heated arbitrarily, which has no influence on the material properties and the grinding surface.
Durability: PMMA material has good weatherability and anti-aging properties. It can be used outdoors for a long time.
Application fields: lighting lamps, lamp box identification, exhibition and display, outdoor lighting, etc
Light guide board: the design principle of light guide board is derived from the LCD of notebook computer, and it is a high-tech product that transforms line light source into surface light source. Optical grade acrylic (PMMA) /pc is the base material. With the technology of LCD display and backlight module of notebook computer, through the high light transmission rate of the light guide point, the light guide point is calculated by computer, so that the light of the light guide plate is refracted into the surface light source in the uniform light state. The product is made by the combination of spectral analysis principle and digital UV printing technology in constant temperature, humidity and dust-free environment. It has the characteristics of ultra thin, super bright, uniform light guide, energy saving, environmental protection, no dark area, durable, not easy to yellow, simple and quick installation and maintenance
The difference between the two:
The functions and functions of ED diffusion plate and light guide plate are totally different
From the material point of view:
The diffusion plate substrate is PC
The base material of the light guide plate is PMMA
From the functional point of view:
The main functions of diffusion plate are:
1: Disperse the light flux and distribute the light evenly (in addition to the uniformity of light, some composite diffusion plates can control the emission angle)
2: Support backlight architecture to protect optical material below
The main functions of the light guide plate are as follows:
1: The light flux of LED point light source is distributed evenly in the whole plane. Its key function is to guide the distribution of light
2: The more efficient use of the optical flux and control of the light distribution by using the reflection mechanism
