Light guide film:
The light guide film is also LGF. Generally speaking, because of its ultra-thin thickness, it feels good when used. This product also has the characteristics of uniform light emission and many color changes. This product is generally used in mobile phones and remote control keys, which can make your keys rich in color.
The working principle of the product is generally based on the use of light reflection and refraction principles, and then combined with special optical software design, so that the optical PC film will be microstructured, and the "point light source" will be expanded into a "surface light source". The light beam can propagate in the medium at a suitable angle and density, so as to achieve an excellent effect of uniform light output.
The LGF light guide film design can generally reduce the design of several LED lights, thereby solving the problems of uneven brightness distribution, large power consumption, large space occupation and high cost.
