Light guide film:
The light guide film (LGF) is generally ultra-thin, so it will not affect the feel. In addition, it also has the characteristics of uniform light emission and more color changes. This product generally acts directly on the buttons of the mobile phone and remote control, so as to allow Your buttons are colorful.
The working principle of the product is to use the principle of light reflection and refraction, and then combine the design of special optical software, so as to carry out the microstructure processing on the optical PC film, which will expand the "point light source" into the "surface light source". Generally, the light beam will propagate from the medium at a suitable angle and density, so as to achieve the excellent effect of uniform light output.
The LGF light guide film design can reduce several LED lamp designs, thereby solving the problems of uneven brightness distribution, large power consumption, large space occupation and high cost.
