SOLAR SECONDARY LIGHT CONCENTRATING FREQUENCY DIVIDING METHOD AND APPARATUS THEREOF BASED ON DISH-LIKE LIGHT CONCENTRATION

摘要

Disclosed are a solar secondary light concentrating frequency dividing method and an apparatus thereof based on dish-like light concentration, a light transmission hole is positioned at the middle of the rotating parabolic dish-like reflector, under the light transmission hole, a light concentrating photovoltaic panel and the inlet of a thermal collector are set on both sides of the axis of the dish-like reflector respectively, a frequency dividing lens is set above the light transmission hole, with a certain distance from the vertex of the dish-like reflector, a frequency dividing film is coated on a curved surface close to the dish-like reflector of the frequency dividing lens, the other curved surface far away from the dish-like reflector of the frequency dividing lens is a silver reflective mirror, a support rod is set between the dish-like reflector and the frequency dividing lens, there is a bracket under the dish-like reflector, which is provided with a biaxial tracking system, the entire system is placed on a chassis. The said method and apparatus thereof enable solar light concentration and frequency dividing, and can transfer the two concentrative focus spots under the system, reduce energy consumption effectively when the system tracks the sun, improve the balance and wind resistance of the system. It is possible to adjust the concentrating ratio of two beams, thereby meeting the best concentrating strength requirements that the light concentrating photovoltaic panel and the thermal collector need.
