The high efficiency light integrator for implementing the utility model has the advantages that the utility model using stainless
Steel sole plate installs eyeglass as the substrate of light integrator, is able to satisfy the use demand of light integrator hot environment；It by its
In one group of lens be mounted in the hollow hole of stainless steel plate, another group of lens using eyeglass pillar support, keep optical path accessible
Only by two groups of lens transmissions, cause additional-energy to be lost by other elements without subsidiary, therefore avoid light
Additional energy loss, helps to improve the system effectiveness of solar simulator entirety.
Detailed description of the invention
Fig. 1 is the exemplary structure schematic diagram according to the high efficiency light integrator of the utility model.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
The utility model provides a kind of high efficiency light integrator, it includes first group of lens and second group of lens, knot
It closes shown in Fig. 1, it further include: stainless steel plate 1 and multiple eyeglass pillars 2,
One group of hollow hole is set in stainless steel plate 1, and one group of hollow hole is for installing first group of lens, stainless steel bottom
Each hollow hole peripheral support has eyeglass pillar 2 on plate 1, and eyeglass pillar 2 makes second group of lens for fixing second group of lens
It is corresponding with the position of first group of lens.
Present embodiment is designed using quartz glass as the light integrator of substrate in contrast to existing, and light is in quartz
When transmitting in the light integrator of substrate, not only also to pass through quartz substrate, therefore energy loss is big by two groups of lens；
And one group of lens is installed in a manner of hollow hole in present embodiment, another group of lens are solid by the eyeglass pillar of outer edge thereof
It is fixed, it ensure that effective transmission of light to greatest extent, to reduce energy loss.
In fact, two groups of lens can also be fixed respectively by the hollow hole of two pieces of stainless steel plates, then not at two pieces
Some support columns are set to determine the distance between two groups of group lens between rust steel plate.At this point, as long as the support of support column number is strong
Degree can satisfy demand.
In present embodiment, supported in such a way that multiple eyeglass pillars are evenly dispersed around hollow hole second group it is saturating
Mirror can obtain the better support effect of stability.
Fig. 1 has carried out simple signal to the utility model, and the hollow hole in stainless steel plate 1 is equipped with first group of lens
Each lens unit；The distribution form of hollow hole needs to be adapted with the distribution form of lens unit in first group of lens.Eyeglass
Pillar 2 supports each lens unit of second group of lens only to be provided in second group of lens as shown in upper left position in figure, in figure
The connection signal of part lens unit.
As shown in connection with fig. 1, in order to cooperate the arrangement form of lens unit in first group of lens, one group of hollow hole can be with
For the one group of hollow hole arranged in honeycomb, the bottom plate gap between adjacent holes and hole is installed empty as the support of eyeglass pillar 2
Between.
In view of the temperature environment of light integrator is close to 1000 DEG C, temperature requirement can satisfy in stainless steel plate 1
On the basis of, the selection of eyeglass pillar 2, which should also meet, additionally light ray energy to be caused to lose, again can high temperature resistant.As showing
Example, the eyeglass pillar 2 can be ceramic leg, and the ceramic leg is resistant to high temperature sintering.
Due to honeycomb arrangement hollow hole the characteristics of, to make second group of lens obtain stable support, eyeglass pillar 2
Distribution form can include: make the evenly dispersed six eyeglass pillars 2 in each hollow hole periphery.The characteristics of honeycomb is arranged is usually every
It is up to six adjacent holes around a centre bore, matches, the position that six eyeglass pillars 2 correspond to six adjacent holes is set
It sets, the support to lens unit equalization stable can be formed；This is equivalent to around each eyeglass pillar 2 most adjacent three hollow outs
Hole.
As an example, 2 head end of eyeglass pillar can be connect with stainless steel plate 1 by No.1 screw.Screw connection
Mode can ensure structural stability, and reduction is deformed as caused by stretching and load-bearing.
As an example, 2 end of eyeglass pillar is connect with second group of lens by No. two screws.No. two screws can incite somebody to action
Lenses are fixedly clamped on the end face of eyeglass pillar 2.
Further, each No. two screw presss from both sides its corresponding all adjacent lens eyeglass with corresponding eyeglass pillar 2 simultaneously
It fastens.Since the eyeglass pillar between adjacent hollow hole is common to the support of corresponding lenses, each eyeglass branch
Column surface can at most overlap the edge of three lenses, at this point, may be implemented by No. two screws to three lenses sides
It is fixed while edge position is with corresponding eyeglass pillar.
In conclusion stainless steel plate and eyeglass pillar that the utility model uses can satisfy the resistance to of each component of integrator
High temperature requirement in turn avoids the loss of light ray energy caused by substrate of glass, helps to improve system effectiveness.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
