Abstract
A combined-type Fresnel lens belongs to the technical field of light energy application. The combined-type Fresnel lens is characterized in that the Fresnel lens is wholly divided into parts; the Fresnel lens comprises a support and fan-shaped Fresnel lenses arranged on the support, with the circle center of the support being as a base point and the 2-degree angle being as the minimum starting point of the fan-shaped Fresnel lenses; and the plurality of fan-shaped Fresnel lenses are arrayed in sequence into a circular or a square Fresnel lens, so that the ultra-large Fresnel Lens can be produced with the lowest die cost.
Description
Technical field:
The present invention relates to a kind of Combined-type Fresnel lens, is light-use technical field.
Background technology:
Existing Fresnel Lenses is with point focusing and line focus, with integral casting forming during fabrication, in the time manufacturing large-scale lens, mfg. moulding die is subject to the restriction of equipment, be difficult to produce superhuge lens, with regard to the Fresnel Lenses of the defocusing type of the patent No. 200610150647.8, be only applicable to defocusing, be not suitable for high temperature and focus on.
Summary of the invention:
The present invention, in order to make up the deficiencies in the prior art, provides a kind of cheap, significant a kind of Combined-type Fresnel lens of effect.
The present invention is achieved through the following technical solutions: a kind of Combined-type Fresnel lens is characterized in that it comprises support and some rack-mount fan-shaped Fresnel Lenses, this every Fresnel Lenses all gathers to same focus, this support is provided with mounting groove, for fan-shaped Fresnel Lenses is installed.
A kind of Combined-type Fresnel lens of the present invention is characterized in that this fan-shaped Fresnel Lenses can be trapezoidal or other can form round any type, is applicable to the optically focused of the Fresnel Lenses of various any geometric type.
A kind of Combined-type Fresnel lens of the present invention is characterized in that the mode of this combination is applicable to a little poly-type and the poly-Fresnel Lenses of type of line and the Fresnel Lenses of other light-focusing type.
A kind of Combined-type Fresnel lens of the present invention is characterized in that the mode of this Fresnel Lenses to break the whole up into parts, it is basic point take the center of circle, the fan-shaped overall Fresnel Lenses of having realized 360 degree take the angle of 2 degree as minimum starting point, some fan-shaped Fresnel Lenses are arranged in order into a circle or square Fresnel Lenses, manufacture ultra-large type Fresnel Lenses for the die cost with minimum.
A Combined-type Fresnel lens of the present invention is characterized in that this is assembled into overall Fresnel Lenses is plane and circular arc or other shape, and scribbles anti-reflection layer on its surface, for improving the utilization factor of light.
The invention has the beneficial effects as follows: manufacture ultra-large type Fresnel Lenses with minimum die cost.
Accompanying drawing explanation:
Fig. 1 is one-piece construction floor map of the present invention.
Fig. 2 is arcuate structure diagrammatic cross-section of the present invention.
Fig. 3 is sector structure floor map of the present invention.
In figure: 1, support, 2, fan-shaped Fresnel Lenses.
Embodiment:
Be described further by reference to the accompanying drawings now: fan-shaped Fresnel Lenses 2 is installed on Fig. 1 medium-height trestle 1.
Buoyancy of the present invention is work like this with gravity force power generation apparatus: the Fresnel Lenses assembling is aimed to sunlight, realize high power concentrator.
