Summary of the invention
Based on this; The purpose of this invention is to provide Salar light-gathering structure of a kind of optical thin film material and preparation method thereof; This concentration structure and preparation method thereof can promote that the interior concentrating component structure of solar high power condense photovoltaic electrification module is anti-aging, outdoor weathe resistance etc., helps reducing the solar high power condense photovoltaic electrification cost, increases tenure of use.
Another object of the present invention is Salar light-gathering structure that provides a kind of optical thin film material and preparation method thereof, and this concentration structure and preparation method thereof is made simple, and is with low cost, has high-weatherability, can anti-soil and hail etc.
For achieving the above object, the present invention realizes like this.
A kind of Salar light-gathering structure of optical thin film material is characterized in that this concentration structure includes Fresnel Lenses and tempered glass, and Fresnel Lenses adheres to and is fixed on the tempered glass, forms concentration structure with tempered glass.
Said Fresnel Lenses is that the silica gel material makes, and the form fix through the silica gel injection moulding forms an optical thin film material Fresnel Lenses structure on the tempered glass basal surface, and this lens arrangement and tempered glass basal surface form a plurality of first incidence surface lens; And second optical surface, it is located at this tempered glass below; By this, this optical film vertically penetrates the incident ray of different angles.
Said optical thin film material Fresnel Lenses structure includes plurality of films collector lens structure, and each film collector lens structure system is ring texture.
Said Fresnel Lenses is the silica gel of high printing opacity.
A kind of preparation method of Salar light-gathering structure of optical thin film material is characterized in that this method at tempered glass surface coverage silica gel, becomes the Fresnel Lenses shape through mould with shaping silica gel then.
Said silica gel is liquid-state silicon gel, earlier liquid-state silicon gel is covered in the tempered glass surface, passes through mould shape again.
Described method is established a Fresnel Lenses structure mold on tempered glass, the surface of this mould has a hole, in order to perfusion silica gel; The inside of mould has a space, holds silica gel, and this space is the Fresnel Lenses structure, and silica gel is full of the shape that can form Fresnel Lenses behind this space, to realize the spotlight effect of Fresnel Lenses.
Above-mentioned mould, the inner wall surface roughness in its space must make the surface present mirror status below 60um, is beneficial to liquid-state silicon gel and flows smooth and easy.
Said tempered glass, its underpart are established a heating arrangement, treat that liquid-state silicon gel is accomplished filling in the structure space of Fresnel Lenses structure mold and tempered glass after, through heating arrangement tempered glass is heated, impel liquid-state silicon gel typing.
The version that the present invention adopts silica gel directly to combine with tempered glass; Broken through the original structural design of Fresnel Lenses; Tempered glass can effectively be protected concentrating component; Make that the concentrating component structure is anti-aging, outdoor weathe resistance good, help reducing the solar high power condense photovoltaic electrification cost, increase tenure of use.
And it is simple, with low cost that the present invention realizes, is convenient to be applied in the various places of solar concentrating photovoltaic power generation.
