Principle：
Using a processing technique that creates a prism-like structure on the surface of the film material, the irregularly refracted and reflected light sources are concentrated on the front side to increase brightness and suppress color deviation, achieving a brightening effect.
Material：
A surface processing method using coating or transfer is used to construct a prism-like structure on the surface of the film material.
Actual test results：
Luminous flux without the attached brightening film: 7.4 lumens.
Luminous flux with the attached brightening film: 16.6 lumens.
Increase in luminous flux by 124%.。
Note: Luminous efficiency may be affected by the structure and material of the illumination module.
