Mirror image focus superposed direction-changeable parallel light energy flux density multiplier

Abstract

This invention is the light energy stream density doubler and design method of mirror image focal point overlapping parallel energy, which style is changeable, it belongs to optics technology application domain, and especially the solar energy condenses the area of technology. This invention is combined of the combination paraboloid condenser, the column catopter and the paraboloid leading the glossy ware by the combination parabola circling the axis of symmetry revolving along the central shaftconnects in turn. Among them , combination paraboloid condenser is obtained like this: The parabola sharpening the edge of flat surface inner making progress translates along the horizontal direction to satisfy the specific condition the distance, after thetranslation parabola and the original parabola intercross, removes the parabola sections having point of inflection on both sides of intersection, obtains a conic combination parabola plane figure , circles its axis of symmetry to revolve then obtains a combination paraboloid. Then truncates its pinnacle part horizontally , and enables the section position to not be lower than the parabola focal point position, also the section width happens to half of focal distance between two parabolas .

Description

Technical field [0001] The invention belongs to the field of optical technology application, in particular to the technical field of solar energy concentration, light guide and solar heat utilization. It can also be used in the fields of convergence and propagation of radio waves. Background technique [0002] To achieve the conversion of the energy flux density of parallel beams or the size of the light-passing area, the general method is to use a combination of lenses or Fresnel mirrors, but the manufacturing cost of this type of lens is relatively high, and it is only suitable for small beams. It is very difficult both technically and economically to manufacture corresponding lenses for light beams with a light-passing area. The invention realizes the conversion of the energy density of parallel beams or the light-passing area of ​​parallel beams by using the principle of parabolic light concentrating and the reflection principle of the cylindrical mirror reflection surf...

Problems solved by technology

In addition, when the ordinary rotating paraboloid converges parallel light, its focus is on one side of the reflective surface, that is, the concave inner side of the paraboloid, which will bring inconvenience to the application in many cases.
