Description

【Technical field】 [0001] The invention relates to the field of optical technology, in particular to a multifunctional light-diverging plate that produces parallel deflection of light and focuses with confocal double parabola reflection. 【Background technique】 [0002] As everyone knows, solar energy is inexhaustible, but people have not yet been able to use it on a large scale. With the reduction of fossil energy such as coal, oil, and natural gas and the continuous rise in price, it has become more and more important for humans to directly obtain energy from solar energy. At present, various solar energy utilization devices have been used, such as photoelectric conversion and photothermal conversion devices. Ordinary light-to-heat conversion equipment is typically equipped with a heat collector tube coated with light absorption and converted into heat energy in multiple glass tubes. The disadvantages are obvious. Because the light energy density per unit area illuminated o...

AI Technical Summary

Problems solved by technology

Ordinary light-to-heat conversion equipment is typically equipped with a heat collector tube coated with light absorption and converted into heat energy in multiple glass tubes. The disadvantages are obvious. Because the light energy density per unit area illuminated on the heat collector tube is small, Therefore, its heat collection efficiency is low, and the cost of solar energy utilization is high; also because of its large heat dissipation surface, it cannot obtain a higher temperature

Ordinary photoelectric conversion equipment is mainly photovoltaic panels, which can convert solar energy into electrical energy, but because photovoltaic panels are expensive, easily damaged, and only have a single power generation purpose, they are inconvenient to install and use, and cannot be used on a large scale

Ordinary parallel light sources are obtained by point light sources or line light sources reflected by paraboloids. They are large in size and cannot be made into plates, so they cannot be used in large quantities for lighting or background light sources.
