Multi-region spectral LGF:
On the basis of conventional LGF, it is generally possible to add a layer of 0.3mm black foam glue to block light transmission and achieve the effect of multi-zone light splitting.
LGF has the characteristics of being ultra-thin without affecting the feel, uniform luminescence and more color changes, etc. Its working principle is generally realized by the principle of light reflection and refraction, and then combined with special optical software design, and finally the optical PC film is microstructured Therefore, it is necessary to expand the "point light source" into a "surface light source". The light beam will generally propagate from the medium at a suitable angle and density to achieve the excellent effect of uniform light output.
