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 the natural light illumination technology in China starts in the sixth and seventy decades of the twentieth century, and since the green illumination engineering promotion in 1996 is carried out to date, the concept of the natural light illumination as a green energy source gradually enters the field of vision of the public, and people have deeper understanding on the natural light collection illumination system along with the continuous deep research on the solar illumination technology. As natural resources such as petroleum and coal are gradually depleted, research and development on solar energy are increasing, and solar energy application technology has the disadvantage that the conversion efficiency of solar energy is low, but the cost is much higher than that of other traditional energy conversion methods, so that the improvement of the utilization efficiency of solar energy and the reduction of the solar energy conversion cost become 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 module to guide sunlight to a solar cell or a heat conduction module through the light guide module, so as to increase the collection efficiency of sunlight and further improve the production efficiency of the solar conversion device. Known solar energy conversion devices require passing through a solar concentrator to concentrate incident sunlight to multiple focal points on the light exit side for use by a solar cell or a heat conducting assembly. However, the focal length of the collected light causes a huge volume of the known solar energy conversion device, 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 sun tracking, but also needs a large-area installation area, the light guide pipe occupying the mainstream of the market at present has low efficiency and poor lighting uniformity, and can damage the original building structure in the installation process, and the popularization and the promotion are not facilitated.
Therefore, how to perform efficient solar lighting without changing the original building structure is a problem that needs to be solved urgently by those skilled in the art.
Disclosure of Invention
The invention aims to solve the problems that the light guide pipe of the existing solar energy conversion device has low efficiency and poor lighting uniformity, and the original building structure is possibly damaged in the installation process, so that the popularization is not facilitated.
The technical scheme adopted by the invention for solving the problems is as follows: the invention comprises a convex lens combination and a semi-plano-convex lens combination; the convex lens combination and the semi-plano-convex lens combination are arranged side by side, and the front face of the convex lens combination and the front face of the semi-plano-convex lens combination face outdoors.
Furthermore, the convex lens combination is formed by arranging a plurality of convex lenses in an array shape, and the semi-plano-convex lens combination is formed by arranging a plurality of semi-plano-convex lenses in an array shape.
Furthermore, the high-angle focusing light of the convex lens falls on the lower end of the semi-plano-convex lens, and the parallel focusing light source of the convex lens falls on the upper end of the semi-plano-convex lens.
Furthermore, the convex lens and the semi-plano-convex lens are made of high-transmissivity materials.
Furthermore, the focal length of the half-plano-convex lens combination is 1-5 times of the focal length of the convex lens combination.
The beneficial effects of the invention are: the invention can efficiently collect the natural light entering the window, uniformly disperse the light to all directions indoors, homogenize the indoor illumination, fully utilize the natural light to carry out the indoor illumination, save energy, reduce emission and improve the energy utilization rate.
