Abstract
The invention discloses a combined-type curved surface line light condensation device, which is composed of a plurality of sequentially arranged light condensation units, wherein the lower parts at two sides of each light condensation unit gradually incline towards the center thereof along the axial direction, the upper end face of the light condensation unit is a circular-arc-shaped light condensation refracting surface, the lower end face of the light condensation unit is a flat surface, the inclined surfaces at two sides of each light condensation unit are of a double curved surface structure which protrudes towards the center and is symmetrically arranged, the outer side of the double curved surface structure is plated with a reflecting material so as to form a reflecting surface, and light refracted by the light condensation refracting surface or light which is firstly refracted by the light condensation refracting surface and then reflected by reflecting surface of the double curved surface structure totally shoots to an area corresponding to the lower end face of the light condensation unit. According to the invention, the two side surfaces of each light condensation unit are designed to be the biconvex structure with a reflecting function, so that all incident light passing through the light condensation refracting surface can be ensured to shot into the area corresponding to the lower end face of the light condensation unit under the condition of reducing the overall thickness of the light condensation unit.
Description
Technical field
The invention belongs to technical field of solar utilization technique, particularly a kind of combined type camberline condenser.
Background technology
Condenser is the vitals of solar photovoltaic spot light subassembly, as shown in Figure 1, current line optically focused adopts the optically focused form of single convex surface, it converges by the light of convex surface to incidence, the shortcoming that this structure mainly exists is that cost is high, and take up room large, focal length is long, and it is large to there is waste of material, the problem that weight is large.
In order to overcome above-mentioned technical matters, there is a kind of lightness condenser at present, as shown in Figure 2, light focusing unit the right and left inactive area in use in Fig. 1 is removed by it, reached saving material, reduced the object of weight, the structure then after its improvement still adopts the optically focused form of single convex surface, cause sink-efficiency not high, and optically focused light path is still longer needed for it, cause integrally-built thickness thicker, preponderance, make mounting bracket requirement of strength higher, install not easily.
Summary of the invention
The object of the invention is to: for above-mentioned Problems existing, provide one to improve sink-efficiency, reduce the combined type camberline condenser of condenser integral thickness.
Technical scheme of the present invention is achieved in that combined type camberline condenser, be made up of some light focusing unit be arranged in order, described light focusing unit two side lower part in axial direction wherein the heart tilt gradually, the upper surface of described light focusing unit is the concentrating refractive face in circular arc, its lower surface is burnishing surface, it is characterized in that: described light focusing unit two lateral incline is to central protuberance and the hyperboloid structure be arranged symmetrically with, outside described hyperboloid structure, be coated with reflecting material form reflecting surface, through the refraction of concentrating refractive face light or all inject the corresponding region, lower surface of light focusing unit through the concentrating refractive face light of refraction again after the reflective surface of hyperboloid structure.
Combined type camberline condenser of the present invention, the transition section that described in it, light focusing unit both sides, upper arcuate section are connected with lower curved face reflecting segment is perpendicular structure, and adjacent two light focusing unit fit tightly arrangement by the transition section place in perpendicular structure.
The present invention is by being designed to the biconvex structure with reflection function by the two sides of light focusing unit, like this can when reducing light focusing unit integral thickness, also can ensure no matter by the incident ray in concentrating refractive face be merely through refraction, or in the reflection again by side after superrefraction, all all can inject the corresponding region, lower surface of light focusing unit, the present invention is by changing incident ray transmission of angle, increase light path, to improve sink-efficiency, the integral thickness of light focusing unit can be reduced simultaneously, comparing existing collector lens by the line collector lens of this structure fabrication can loss of weight about 42%, thus close to the weight of dull and stereotyped crystal silicon sun assembly.
