Description
Technical Field
The invention relates to a natural light homogenizing lighting device, and belongs to the technical field of lighting systems.
Background
The research and development of natural light illumination technology in China starts in the twentieth century and seventies, and the green energy concept of natural light illumination gradually enters the public view since the green illumination engineering in 1996 is popularized, so that people have deeper understanding on a natural light acquisition illumination system along with the continuous deep research of solar energy illumination technology. As natural resources such as petroleum and coal are gradually depleted, research on solar energy is increasingly developed, and the disadvantage of the solar energy application technology is that the conversion efficiency of solar energy is low, but compared with other traditional energy conversion modes, the cost is much higher, so that the improvement of the solar energy utilization efficiency and the reduction of the solar energy conversion cost are important targets in recent research.
In order to improve the utilization efficiency of sunlight, one method is to use a solar collector combined with a light guide assembly module to guide the sunlight to a solar cell or a heat conduction assembly through the guide of the light guide assembly, so as to increase the collection efficiency of the sunlight and further improve the production efficiency of the solar energy conversion device. Known solar energy conversion devices require passing through a solar collector to concentrate incident sunlight to multiple focal points on the light exit side for use with a solar cell or heat conduction assembly. However, the focal length of the converging light causes a huge volume of the known solar energy conversion device, and the large-volume solar energy conversion device not only needs to consume higher manufacturing and material cost and is difficult to precisely move and control the sun to track, but also needs a large-area installation area, so that the light guide tube occupying the main stream of the market at present has low efficiency and poor lighting uniformity, and the original building structure is possibly damaged in the installation process, thereby being unfavorable for popularization.
Therefore, how to perform efficient solar lighting without changing the original building structure is a problem to be solved by those skilled in the art.
