The light sources of back lit LED panel light are LED chips, there is a distance between LEDs, so it is unavoidable to produce light spot . Lighting industries always take use of the diffusion plate HT80-M to make lamp with uniformity light.
For settling light spot of back lit LED panel lights, why do we choose diffusion plate HT80-M? Let’s look the features of diffusion plate HT80-M.
1. The superior materials of this diffusion plate HT80-M is imported optical level PMMA.
2. High light transmittance up to 82%, high diffusion efficiency up to 92%, using advanced optical design and diffusion material, can adjust the lighting direction, enhance the optical brightness and diffusion effect.
3. One side of diffusion plate is matte, and other side is glossy. You should put the matte side outward when you use it, because three points as below.
a. Glossy side as the lamp surface is easy to fouling.
b. Matte side as the lamp surface is not easy to bruise and scratch.
c. Enhance the light transmitting efficiency(the conclusion of the integrating sphere test)
1. Suitable for back lit LED lamp, such as LED tube light, LED grille light etc. If you install it on the LED tube light, the smallest light failure is 10%.
2. Suitable for side lit LED lamp, such as some side lit LED panel light, and this diffusion plates are always used with light guide plate.
