What is the principle of reflection for a car photograph? What material is it made of?
3. micro prism structure: micro prism technology is different from ordinary reflective film used by the principle of micro glass beads, each micro prism cube angle link arrangement, forming a precise reflection array. The reflective film made by using the technique has not only more than a few times increase in reflection efficiency, but also wide angle performance. It is also the only reflective material with long distance and wide angle.
The reflective principle: 1. rare earth reflection: using visible light (electromagnetic wave length of 0.77-0.39 microns) activation of rare earth luminescent materials in Eu3+, Dy3+ and other elements, storage of light in the dark can emit yellow green light wavelength is 450~600nm. Based on the principle of luminescence, the rare earth luminescent material is applied to reflective material. 2. glass bead structure of reflective type: using high refractive index glass beads as the aluminum retroreflector, with retro reflective properties strong, most of the light can be directly reflected to the light source, resulting in the reflective brightness.
Reflective materials are conventionally classified into four grades: advertising, engineering, high strength and diamond grade. But according to their classification, they are: rare earth reflective glass, micro bead structure, reflective type and micro prism structure, reflective type
