Diffuse reflection is the light projected on a rough surface and the phenomenon of direction reflection . When a bunch of parallel light hits a rough surface, the surface reflects the light in all directions, so the incident line is parallel to each other, and because the normal direction of the points is inconsistent, which causes reflection ray to reflect irregularly in different directions ,that is called "diffuse reflection", and the reflected light is called diffuse light, shown in the picture below:
Diffuse reflection color coated aluminum sheet is the use of the diffuse reflection principle of light, the use of coating with diffuse reflection function and special roller coating process coated with a layer of coating, combined with nano-scale small particle technology, in the coating surface to form a small uneven surface, and let the reflectivity of the light exposed to the surface of the coating to reach the reflection rate more than 95%. When light diffuses on the surface of an object, we can see the surface from different angles.

(1) It will not produce reflective phenomenon, we can clearly see the coating surface from any angle ,no light pollution;
(2) High reflectivity. In the same space and the same power of the light source conditions, the use of diffuse coating sheet decoration of the room brightness is higher, it not only can achieve the purpose of energy saving, but also can make the layout of the light source more scientific and reasonable;
(3) Much low gloss, only 3-5 degrees, is a super matte coating, and also has a very good bending performance;
(4) Solve the disadvantages of dazzling and vertigo brought by mirror reflection, and make the light soft and warm.
