Natural light homogenization lighting device based on combination of biconvex lenses and semi-transparent lenses

Abstract

The present invention relates to a natural light homogenization lighting device, and particularly relates to a natural light homogenization lighting device based on combination of biconvex lenses and semi-transparent lenses. The present invention aims to solve the problems of low efficiency and poor lighting uniformity of light pipes, and possible damage to the original building structure in the process of installation and not conducive to the promotion and popularization of the existing solar energy conversion devices. The device of the present invention includes a positive lens combination and a positive half-lens combination; the positive lens combination and the positive half-lens combination are arranged side by side, the positive lens combination is located outdoors, and the positive half-lens combination is located indoors. The present invention belongs to the technical field of lighting systems.
