Film expands to form balloon, the reflectance coating（3）Because pressure differential deformation forms a upward space matrix in optically focused ball interior
Segment, the focus of the matrix segment that the reflectance coating is formed is located at the centre of sphere, and light is reflexed in focus；The solar energy
Receiver is located at the centre of sphere of condenser ball；The reflected film of incident light so through the episphere hyaline membrane is reflexed to positioned at institute
State the solar receiver of the focal point in condenser ball.
The above reflectance coating is the elastic membrane with reflecting coating, including base material, is plated on the even surface of the base material
There is reflecting material or be stained with reflectance coating, clear protective film layer is coated with the reflecting material or reflectance coating.
The above reflecting material is aluminium or silver, and the reflectance coating is metallized film or silver plating film.
The above clear protective film layer is polytetrafluoroethylene (PTFE), liquid glass or polyvinyl fluoride.
The above Salar light-gathering ball also includes control solar concentrator pitching and the solar tracking tracker for horizontally rotating.
The radial direction or broadwise of condenser ball of the invention are provided with reinforcement, and reinforcement converges at the two-stage of condenser ball, optically focused
The two poles of the earth of ball are provided with rotating shaft and fix, and rotating shaft plane is parallel with plane where condenser ball equator, and rotating shaft can realize Double-directional rotary, turn
Axle is fixed on a support for radial belt base of condenser ball, and base can realize 360 degree of rotations, and all of rotation is equal with rotation
Controlled to ensure solar energy reflection film all in optimal working condition by solar tracking tracker.
The present invention has the advantage that with prior art：
Condenser ball of the invention is by that with above-mentioned composition, can carry out the optically focused of wide range（Such as Omnibearing light-collecting）.
