Description
Technical field
The invention belongs to sun optically focused technical field, especially relate to a kind of miniature Salar light-gathering lens.
Background technology
Sun power is as a kind of nuclear fusion energy, and day by day exhausted along with mineral fuel on the earth will become the important component part in energy family.The mankind are more and more general to the utilization of sun power at present, except the indoor lighting that is used for of passive type, and building heating and domestic hot-water, active solar energy utilizes technology to be converted to sun power the other forms of energy and to obtain more wide application prospect.Solar electrical energy generation is based on this.
CPV is most typical representative in the concentration solar generating technology, utilizes the Photospot solar technology of generating after utilizing optical element that sunshine is converged again, and is considered to the third generation technology of solar electrical energy generation future developing trend.
The optically focused of optical element is most important part in concentration module, and it has determined the efficiency of whole system, and at present, the optical element that concentration module adopts is larger, and spotlight effect is not ideal enough, system complex, and cost is higher.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned deficiency of the prior art, and a kind of miniature Salar light-gathering lens are provided, and the present invention is simple in structure, and is reasonable in design, it is convenient to realize, light gathering efficiency is high, and volume is little, realize that cost is low, spotlight effect is good, and popularizing application prospect is extensive.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of miniature Salar light-gathering lens, it is characterized in that: the first lens and the Fresnel Lenses that is arranged on first lens plane of incidence top that comprise the inverted round stage shape, the lower surface of described first lens is formed by the set of a plurality of microreflection face, described first lens inner inclination is provided with a plurality of secondary reflection faces, and the lower surface center position of described first lens is provided with exit facet.
Above-mentioned a kind of miniature Salar light-gathering lens is characterized in that: described secondary reflection face surface is provided with for sunshine being carried out the reflectance coating of secondary reflection.
Above-mentioned a kind of miniature Salar light-gathering lens is characterized in that: a plurality of described microreflection faces all are obliquely installed and match with the angle of inclination of a plurality of secondary reflection faces.

Embodiment
As shown in Figure 1, the present invention includes the first lens and the Fresnel Lenses 3 that is arranged on the first lens plane of incidence 5 tops of inverted round stage shape, the lower surface of described first lens is formed by a plurality of microreflection face 1 set, described first lens inner inclination is provided with a plurality of secondary reflection faces 2, and the lower surface center position of described first lens is provided with exit facet 4.
As shown in Figure 1, in the present embodiment, described secondary reflection face 2 surfaces are provided with for sunshine being carried out the reflectance coating of secondary reflection, the light that microreflection face 1 penetrates can be carried out secondary reflection, also the light of direct incident can be carried out Multi reflection in secondary reflection face 2 forms face territory, thus the polymerization outgoing.A plurality of described microreflection faces 1 all are obliquely installed and match with the angle of inclination of a plurality of secondary reflection faces 2.The lower surface of described first lens is provided with reflectance coating.The described first lens plane of incidence 5 surfaces are provided with transmission film.
principle of work of the present invention and the course of work are: Fresnel Lenses 3 converges the sunray of incident, the first lens plane of incidence 5 surfaces be provided with transmission film can with the irradiation sunray with high transmittance incident, microreflection face 1 forms integrated reflecting surface with the array format set, the light of incident through little integrated microreflection face 1 with the light convergence reflex to secondary reflection face 2, owing to being coated with reflectance coating on secondary reflection face 2, light is after 2 reflections of secondary reflection face, by exit facet 4 outgoing, simultaneously, when the light direct irradiation is on secondary reflection face 2, can repeatedly launch in secondary reflection face 2 forms face territory, thereby through exit facet 4 outgoing.
In sum, the present invention carries out in lens inside the purpose that Multi reflection reaches light polymerization outgoing with light, realizes light optically focused with this, realizes that cost is low, and light gathering efficiency is high, and spotlight effect is good, and popularizing application prospect is extensive.
The above; it is only preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection domain of technical solution of the present invention.
