Light converging method via multi-level series confocal conic surface secondary reflection units

Abstract

The present invention provides a method for obtaining high energy density and high brightness converged light via the convergence of multi-level series confocal conic surface secondary reflection units. The light convergence system of the method comprises multi-level light converging layers, and may also comprise planar reflecting layers or light-reflecting channels. The multi-level converging layers are directly connected in series, or the multi-level converging layers, the planar reflecting layers and the light-reflecting channels are connected in tree form in series, to form the light convergence system. The total convergence ratio of the light convergence system is sum of products of the convergence ratios of all levels of the secondary reflection units. Each level of the light converging layers is composed of a plurality of confocal conic surface secondary reflection units having special light converging effect; non-converging planar reflecting layers or light reflecting channel layers may be disposed among light converging layers, and are used for transferring the light into the next level converging layer or for output; and new incident light may be arranged among the multi-level light converging layers. The method can be widely used in a variety of occasions that need to enhance light signals, light energy density, and brightness, and will play an important role in the field of optics, solar energy utilization, etc.

Description

technical field [0001] The invention relates to a method for converging light, in particular to a method for obtaining converging light with high luminous energy density and high luminance by converging conical curved surface secondary reflection units with multi-stage series concentricity. Background technique [0002] Conics include parabolas, hyperbolas, and ellipses, and parabolas, hyperbolas, and ellipses have their own characteristic optical properties. The optical property of the parabola: the light parallel to the axis of symmetry is reflected by the rotating parabola (the surface generated by the parabola rotating around the axis), and all pass through the focus; otherwise, the light emitted from the focus becomes parallel after being reflected by the rotating parabola. The optical properties of the hyperbola: After the light emitted from one focus of the hyperbola is reflected by the hyperboloid of rotation (the rotating surface generated by the hyperbola rotating ...

Problems solved by technology

[0004] Among the combined light converging technologies that are currently used more often: the plane reflection method mostly adopts the reflection of multiple plane mirrors to obtain the converging light, such as CN101196612A, but its converging is relatively small; the optical lens method is limited by the size of the components, so it is not suitable for larger areas and Convergence of light over a longer distance; although the curved surface reflection method has involved the secondary reflection of the conical surface with confocal points, it mostly uses a single-stage form of two parabolic confocal combinations, such as patents CN101726843A, CN102062937A, and CN201917709U

None of the above methods can or is not easy to obtain converging light with extremely high luminous energy density and high brightness.
