Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of beam condensing unit sunshine light-guiding mechanism is provided.This beam condensing unit is simple in structure with sunshine light-guiding mechanism, volume is little, the utilization rate of raising luminous energy, has broad application prospects.
For achieving the above object, the technical solution used in the present invention is: beam condensing unit sunshine light-guiding mechanism, it is characterized in that: comprise shading support and be arranged on convex lens and the paraboloidal mirror in described shading support, described shading support is the cylinder of a hollow, one end of described shading support is provided with cover plate, and the outward flange of described cover plate is provided with for being fastened on the fastener on shading support, the other end of described shading support is opening, described convex lens are arranged on the openend of shading support and the convex surface of the convex lens outside towards shading support, the inwall of described shading support is provided with the bracing frame for supporting paraboloidal mirror, described convex lens and paraboloidal mirror space, the optical axis of described convex lens and the optical axis of paraboloidal mirror are located on the same line, described paraboloidal mirror is connected with optical fiber away from the one side of convex lens, described optical fiber passes cover plate, and described optical fiber and cover plate closely cooperate, the inwall of described shading support is provided with the multiple grooves for clamping bracing frame, one end of described groove extends to one end away from convex lens in shading stent length direction, described convex lens are made of plastics, and the outer surface of described convex lens scribbles anti-reflection film, the outer surface of described paraboloidal mirror is coated with reflective film, described optical fiber is hollow network structure.
Above-mentioned beam condensing unit sunshine light-guiding mechanism, is characterized in that: described optical fiber is connected with paraboloidal mirror by sealing ring.
Above-mentioned beam condensing unit sunshine light-guiding mechanism, is characterized in that: the one end near convex lens on described groove is provided with for preventing the block of paraboloidal mirror near convex lens.
The present invention compared with prior art has the following advantages:
1, of the present invention simple in structure, rationally novel in design, be easy to install.
2,, when the present invention uses, sunshine planoconvex lens becomes a fritter face region after focusing on, then through paraboloidal mirror secondary focusing laggard enter the light of optical fiber more, still less, the light that can not cause entering in optical fiber because of the little error of tracking system like this reduces sharply in loss.
3, the present invention moves in groove by bracing frame, has facilitated the installation of bracing frame and paraboloidal mirror, also the convenient adjustment to spacing between paraboloidal mirror and convex lens.
4, of the present invention to realize cost low, and result of use is good, is convenient to promote the use of.
In sum, the present invention is simple in structure, and rationally novel in design, functional reliability is high, long service life, and the utilization rate of raising luminous energy, has broad application prospects.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
