Abstract
The invention discloses a solar energy light-concentration device, aiming at improving the luminous intensity on unit area so as to make better use of the solar energy. The solar energy light-concentration device comprises a rotating reflective surface (1), a rotating reflective surface (2) and a solar panel (3). The light on the rotating reflective surface (1) is fully reflected to the rotating reflective surface (2) which then reflects the light to a hole (4) at the top of the rotating reflective surface (1), and then the light is emitted and concentrated on the solar panel (3) and is convenient for use. The solar energy light-concentration device is widely applied to the solar energy generation.
Description
Technical field
The present invention relates to a kind of solar-energy light collector.
Background technology
Now, solar power generation more and more causes people's attention as a kind of clean energy resource.But because solar conversion efficiency is low, reasons such as input cost height have seriously hindered applying of solar energy, market presses for heliotechnics can break through the too high bottleneck of cost, obtains popularizing of large tracts of land high speed, brings into play due advantage for solving the energy scarcity environmental pollution.
Summary of the invention
Technical problem to be solved by this invention is to utilize solar-energy light collector, improves the luminous intensity on the unit are, so that just can obtain more electric energy with less solar panel.
The technical solution adopted in the present invention is: the present invention includes rotation reflective surface I, rotation reflective surface II and solar panel, described solar panel is arranged near the hole of being opened at rotation position, reflective surface I summit, described rotation reflective surface II is the sunlight by described rotation reflective surface I total reflection, is totally reflected to described rotation reflective surface position, I summit again and penetrates from described hole to concentrate on the solar panel.
Described rotation reflective surface I is a paraboloid of revolution reflective surface or the combination of a plurality of paraboloid of revolution reflective surface.
Described rotation reflective surface II is a paraboloid of revolution reflective surface or the combination of a plurality of paraboloid of revolution reflective surface.
Described rotation reflective surface II is a hyperboloid of revolution reflective surface or the combination of a plurality of hyperboloid of revolution reflective surface.
The invention has the beneficial effects as follows: sunlight is by rotation reflective surface I, focus on the very little unit are behind rotation reflective surface II two secondary reflections, luminous intensity on the unit are will improve manyfold, very little solar panel is placed on this position, the luminous energy that the luminous energy that produces can produce with the solar panel of rotation reflective surface I frontal area size is close, because solar panel costs an arm and a leg, this invention will significantly reduce cost; The present invention is simple in structure, is easy to produce protection easy to use and cleaning.
In addition, described rotation reflective surface I can be combined by a plurality of paraboloid of revolution reflective surfaces, described rotation reflective surface II can be combined by a plurality of paraboloid of revolution reflective surfaces or a plurality of hyperboloid of revolution reflective surface, variation along with light angle, can adapt to different incident angles, make the maximization of light collecting efficiency.
