Light Diffuser Sheet
The point or direct type light source go through the diffuser sheet to make the illuminant homogenization.
Character
Excellent optical dispersion and high transmittance, it can get the more brightness based on the same light source, making the light diffusion effect get the best condition and reduce light source energy consumption effectively.
The color temperature is stable and color rendering index does not fall, it can totally keep the natural color of LED.
Using the light of direct type cold cathode tub, it is uniform, so it will not see the shadow of shine area.
Heat-resistant, impact resistant, dimension stability, good flatness.
Easy cutting process ,low-cost, it can be bending and thermoforming.
Specification:
The color is milky white, the surface has matte effect.
Size: 1210X1210 X 1.5/2mm are our normal product, if you need other specification and order quantity is large, we also can do them.
Application
Side and direct light resource flat lamp.
The sheet can be employed in super-thin lamp box, liquid crystal TV set, luminous painted wall and medical equipment.
Instruction
When you make LED lamp, you should choose different principle and design diffuser plate according to your using, light distribution curve and illumination requirement.
The comparison between light diffusion sheet and normal milky white organic sheet :
Item |
Organic sheet |
Light diffusion sheet |
Light transmittance |
Added inorganic color masterbatch(such as titanium dioxide, talcum powder), making more light reflection and obsorption, but only less light will come out. |
It can get 84%. And we also can adjust according to customer's requirement.
It is composed by colorless special light particles. |
Uniform light |
It will be yellow after a long time |
92% |
Color rendering |
Color rendering is bad |
Good color rendering, not only change the light direction |
Reflection |
The smooth surface will have reflection |
Matte surface can avoid the reflection |
