Abstract

The utility model relates to an improved light gathering component of a Fresnel lens. The light gathering component of the Fresnel lens comprises a Fresnel lens, a bonding layer and toughened glass; the toughened glass is fixed on the back face of the Fresnel lens by the bonding layer; the toughened glass effectively isolates an ultraviolet part in sunlight from the glass; and the remaining light is gathered to a light gathering plane at a predetermined position by the Fresnel lens. The light gathering component can improve a light gathering component structure in a solar high-power light-gathering photovoltaic power generation module and is ageing resistant, strong in outdoor weather-resisting property and easy to wash.

Description

A kind of Fresnel Lenses concentrating component

Technical field

The utility model relates to Fresnel Lenses, the Fresnel Lenses concentrating component of saying so exactly and being used in the tempered glass protection, and this component application is in the solar high power condense photovoltaic electrification module.

Background technology

The solar photovoltaic technology let us is enjoyed the clean reproducible energy that the sun gives; And a necessary important concentrating component is exactly the concentrating component that is formed by Fresnel Lenses in the solar high power condense photovoltaic electrification module; Concentrating component structure in the existing sun ability high power condense photovoltaic electrification module; System adopts the sensitive surface of the Fresnel Lenses concentrating component of acrylic moulding directly to expose outside, does not have any protection.

Like No. 201010146844.9, patented claim described " manufacturing approach of nanometer self-cleaning spotlight solar energy Fresnel lens "; This application discloses a kind of manufacturing approach of nanometer self-cleaning spotlight solar energy Fresnel lens, and this method is that an acrylic board is carried out the hot-forming Fresnel Lenses that one side has nano-micro structure that forms on hot-press base plate.Adopt this method can produce the Fresnel Lenses of nano-micro structure very easily, cost is lower, processes simple and convenient.The concentrating component of this method made still is the acrylic moulding, and is poor in outdoor weathe resistance, low, the easy loss of heatproof, damage easily, and tenure of use is short, and this is a serious problem concerning the concentrating component of the long-term use out of doors of needs.Often increase considerably the cost and reduction generating efficiency of solar concentrating photovoltaic power generation.

Summary of the invention

Based on this, the purpose of the utility model provides a kind of improved Fresnel Lenses concentrating component, and this concentrating component can promote the interior concentrating component structure of solar high power condense photovoltaic electrification module, and anti-aging, outdoor weathe resistance is strong, be prone to clean.

Another purpose of the utility model provides a kind of Fresnel Lenses concentrating component; This concentrating component combines with Fresnel Lenses through tempered glass; Heatproof is high, weatherability is good, indeformable, not yellow of concentrating component etc.; Tempered glass can effectively intercept solar ultraviolet, reaches long target tenure of use.

For achieving the above object, the utility model is to realize like this.

A kind of Fresnel Lenses concentrating component; It is characterized in that said concentrating component has Fresnel Lenses, bonding coat and tempered glass; Tempered glass is fixed on the Fresnel Lenses back side through bonding coat; The tempered glass assembly effectively partly isolates from the sunshine middle-ultraviolet lamp outside the glass, all the other light again via this Fresnel Lenses with the caustic surface of light-ray condensing in a precalculated position.

Bonding coat; Be silica gel or other binder, its effect one is to have suitable stickiness, makes tempered glass and Fresnel Lenses stably fixing; The 2nd, do not influence the transmission of light in bonding coat, light can be injected into the Fresnel Lenses from tempered glass without barrier.Since or select the good binder of translucent effect for use, and perhaps select thin bonding coat for use, can reach does not influence the effect that light is injected.

A described Fresnel Lenses and a tempered glass; Wherein, tempered glass is greater than Fresnel Lenses, and said Fresnel Lenses is with single or array mode; Bind or be fixed on the tempered glass; The formed optically focused spare of this Fresnel Lenses is bonding on the tempered glass basal surface and is formed with a plurality of first and penetrates incidence surface, and second exiting surface, and it is located at this tempered glass assembly below; By this, the Fresnel concentration structure lens of this acrylic moulding system vertically penetrates the incident ray of different angles.

Said Fresnel Lenses, it is consistent with the bonding coat size.

Said Fresnel Lenses is the acrylic material moulding, comprises member single or the array mode, binds or is positioned over processing procedure on the tempered glass, and wherein, each member system is ring texture.

The utility model adopts the form of Fresnel Lenses and tempered glass combination, and tempered glass can effectively partly isolate from the sunshine middle-ultraviolet lamp outside the glass, all the other light again via this Fresnel Lenses with the caustic surface of light-ray condensing in a precalculated position.Can improve the concentrating component structure in the solar high power condense photovoltaic electrification module through tempered glass, increase ageing resistance, make strong, the easy cleaning of its outdoor weathe resistance.

And the utility model is realized easy, with low cost, can be widely used in the existing various solar photovoltaic spot light power generation process.

Fig. 3 is the single structure schematic perspective view.

Wherein: 1 is tempered glass, and 2 is liquid-state silicon gel, and 3 is Fresnel Lenses, 4, sunshine is through direct of travel behind the Fresnel Lenses, and 5 is caustic surface.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done into description.

Like Fig. 1 and shown in Figure 2; The processing procedure of the concentrating component structure in the solar high power condense photovoltaic electrification module of the utility model comprises tempered glass assembly 1, liquid-state silicon gel 2 and acrylic material Fresnel Lenses 3; Wherein acrylic material Fresnel Lenses 3 comprises a plurality of structure lens; These structure lens jacket annulars are arranged layer by layer, constitute Fresnel Lenses 3.The number of plies and the diameter of structure lens are confirmed according to designing requirement.

Get tempered glass 1 earlier, the size of tempered glass is convenient to adopt frame clamping tempered glass greater than Fresnel Lenses; On tempered glass 1, use fixedly tempered glass 1 of frame; Again elite liquid-state silicon gel 2 is poured into and wherein overflowed whole tempered glass 1 framework (perhaps liquid silica gel 2 being coated on the tempered glass 1 equably); Again one by one with the structure lens of acrylic material Fresnel Lenses 3; Be parallel to tempered glass 1 and place, promptly obtain basic Fresnel Lenses concentrating component.

But this Fresnel Lenses concentrating component can not directly use, and also will carry out deaeration and curing, and Fresnel Lenses and tempered glass are combined closely; Promptly carrying out vacuum defoamation with the vacuum machine again handles; Putting into large-scale baking box after accomplishing vacuum defoamation,, can take out (baking temperature is generally) through after waiting for a period of time with the heat baking; Remove frame, accomplish a processing procedure.

The Fresnel Lenses concentrating component that is made into is as shown in Figure 3, is coated with silica gel 2 on the tempered glass 1, is bonded with the Fresnel Lenses parallel with tempered glass 3 on the silica gel 2.Fresnel Lenses, its profile can be the above polygon of circular, square, triangle, ellipse, pentagon or the geometric configuration of Else Rule.

In a word, the above is merely the preferred embodiment of the utility model, is not the scope that is used for limiting the utility model embodiment.Be that all equalizations of being done according to the utility model claim change and modification, all in the claim of the utility model.
