摘要
光扩散膜的作用是将LED的点状光源均匀转换成面光源,达到匀光的效果。扩散膜其匀光原理系利用光在不同折射率的介质中穿过,使光线产生许多折射、反射、散射,获得光学扩散的效果。选用紫外光聚合物转印技术,建立小批量光扩散膜转移复制工艺。
Diffuse film turns a spot LED light source into a surface source achieving light averaging. The main mechanism of diffuse film is multi reflection, refraction and diffraction of light in different media with dissimilar refractivity. This paper employs the technology of UV image transfer on polymer, achieving a diffuse film image transfer craft for small scale manufactory.
