Abstract
The utility model relates to an optically-focused solar energy dodging member. The dodging member is a lens-reflecting concentrator. The front of the dodging member is a lens while the rear end is a total-reflection light guide cone. The front and the rear end which are integral are made of the same materials. The caliber of the front is larger than that of the rear end. The rear end has a caliber with the same size as that of a receiver. Light rays are focused through the lens and then undergo once or twice total reflection through the total-reflection light guide cone before being projected to a specific area of the receiver. The dodging member provided by the utility model increases the uniformity of the light rays received by the receiver, expands the receiving angle of a system and lowers the tracking precision and the manufacturing precision of the system.

Technical field
The utility model relates to application of solar.
Background technology
Sun power is a kind of inexhaustible clear energy sources, has become the emphasis of modern society's development of resources at present.In the utilization to solar electrical energy generation, the development of Photospot solar has become an important direction.The Photospot solar technology is by light collecting device large-area sunlight to be focused on the little receiving device, has effectively reduced the consumption of semiconductor material, decrease system cost.
Light balancing device is indispensable device in the Photospot solar system.Generally be to adopt optical prism or light funnel at present.Optical prism is through Multi reflection sunlight to be reflexed to the receiver surface uniformly, shortcoming be tracking accuracy when high light line deviation angle is not larger light losing serious, the light reflection that wide-angle can not be departed from has caused the waste of energy to the receiver surface.The light funnel is through reflection sunshine to be reflexed on the receiver surface, and shortcoming is that sun reflection of light has energy loss, and the hot spot that receiver receives is inhomogeneous.
The utility model content
The utility model patent is for the deficiency of the existence of above-mentioned prior art, proposed a kind of light balancing device for can wide-angle collecting the Photospot solar of sunshine and effectively even light.Described light balancing device is a kind of lens-reflecting condenser, and its front end is lens, and the rear end is total reflection leaded light cone, and the rear and front end is as a global existence, is comprised of the material of identical material, and the size of rear end bore is identical with receiver.Rays pass through lens focuses on the specific region that light is projected receiver through once or twice total reflection by reflecting prism.
Its technical solution is as follows:
A kind of light balancing device for Photospot solar, it is characterized in that: described light balancing device is a kind of lens-reflecting condenser, its front end is lens, the rear end is total reflection leaded light cone, the rear and front end is as a global existence, material by identical material forms, and the front end bore is greater than the rear end bore, and the size of rear end bore is identical with receiver.Described light balancing device front end is lens, and the rear end is total reflection leaded light cone, and the light of wide-angle deviation carries out total reflection through total reflection leaded light cone, and then gets on the surface of receiver through behind the lens focus.The lens of front end play the effect of focusing, can focus on arrive total reflection leaded light cone to the light of wide-angle deviation and be low-angle light, so light can carry out total reflection in total reflection leaded light cone, without any energy loss.And through behind the lens focus, the total length of whole light balancing device reduces greatly than original optical prism structure.
The lens of described light balancing device-total reflection leaded light is bored as a global existence, is comprised of identical material optical glass, and comparison is convenient, simple.
The total reflection leaded light cone flank face of described light balancing device can be plane or composite parabolic, and its concrete parameter can utilize non-image-forming principle to carry out design modifying according to concrete requirement, so that stray light all reflexes to the surface of receiver.
The end face of described light balancing device is coated with anti-reflection film, has reduced the end face loss, so that more light can arrive the receiver surface, can utilize more fully energy.
The light balancing device of the utility model patent places the top of solar receiver and close as much as possible solar receiver when being used for Photospot solar.Sunshine focuses on the light balancing device through condenser system, and through lens focus, total reflection leaded light cone carries out total reflection, reflexes to the specific region of solar receiver.
Compared with prior art, the utility model patent has the following advantages:
(1) a kind of Photospot solar light balancing device is a kind of lens-reflecting condenser, and its front end is lens, and the rear end is total reflection leaded light cone, and the rear and front end is as a global existence, is comprised of the material of identical material, makes more convenient, simple.
(2) scioptics have not only increased the angle that receives light to the light focusing of large deviation, and so that the total length of light uniforming device greatly reduce.
(3) carry out total reflection by total reflection leaded light cone, without any energy loss.
(4) end face of light uniforming device is coated with anti-reflection film and has further reduced energy loss, has utilized fully energy.
