Abstract

The invention relates to a method and lens arrangement for light focusing. The method and lens arrangement (1) according to the invention enable the merging of light beams (3, 4) coming from different directions into one focal point (7), and to convert them into parallel light (4), if necessary, to transmit them via light guides (6), and/or to supply them for a different suitable use. Different light spots in a room are overlapped into a focal point (7). This process can theoretically be repeated indefinitely. In this manner extremely high amounts of light can be focused.

Method and lens arrangement for light concentration

[Description]

The invention relates to a method and a lens arrangement for light concentration from different directions with which a high energy concentration is generated for energy production by superposition of light rays detected by lenses.

The focusing of light by means of converging lenses has occupied an important position in many technical fields. Particular attention is given here to parallel light beams, which can be individually focused but also converted back into parallel light.

Even with the use of solar energy, light concentrations play an increasingly important role. Unfortunately, only a limited light bundling is possible with the known arrangements using converging lenses. A single converging lens can focus only ordered light rays coming from one direction into a focal point. Light from different directions or origins can not focus the condenser lens in the current form. Alignment of such disordered light rays into parallel rays is not possible in the current state of the art.

In addition, all known methods of light bundling only allow a limited light bundling in one focal point.

OBJECT OF THE INVENTION

The object of the invention is to provide a method and a lens arrangement for light concentration, with the light from different parallel and non-parallel directions in high concentration in a focal point is bundled to then convert it depending on the application in parallel light or to another use. In particular, an optimal light concentration should be achieved for optimum utilization of solar energy.

The object is achieved in terms of the method with the features of the first claim and with respect to the lens assembly with the 7th claim. Advantageous developments and refinements are the subject of the dependent claims.

The method and the lens assembly concentrates the light from different directions such that light rays from different directions and / or parallel light rays are detected by a plurality of lens or lens systems and concentrated on a common focus and then behind the focal point, the light rays passing through the focal point another lens or lens system can be converted into parallel light rays.

The lens array for light concentration of light rays consists of at least two lenses or lens systems aligned with each other such that a light spot located in front of the lens in the optical axis or an already focused focal spot replicates behind the lens Points of light in a point of light merge by overlapping and a common new focal point arises.

In contrast to the principle of concentrating light of conventional condenser lenses, the invention does not necessarily use parallel light beams for focusing a focal point, but light emanating from a point in space of natural or artificial origin or an already focused focal point.

A conventional lens focuses parallel light into a focal point with which the light concentration is completed.

In contrast, in the present invention, not only parallel light beams but also light beams of different speeds are used. tion, which intersect as points of light, focused by superposition in a common focal point. At the common focal point thus created, a high point accuracy can be achieved.

The newly created focal point can be easily fed into a light guide and thus transported. For this reason, the lenses are also able to work regardless of location. Several newly created foci could now be the output of a new light concentration to create a new focal point. This process can be repeated in successive stages.

Again, it is also possible to convert the newly formed focal point into parallel light, whereby originally non-parallel light rays are converted into parallel light rays.

Since the lens can fuse different light sources into one focal point, it has the possibility of combining different light properties.

The solution according to the invention makes it possible to combine entire solar collector fields with one another in order to obtain extremely high energy concentrations.

With reference to drawings, the structure and operation of the invention will be explained in more detail.

In Fig. 1, a part of the lens arrangement 1 is shown according to the invention, the z. B. light 3 (shown in Fig. 9) from different directions in a focal point 7 can focus.

For a better explanation, the state of the art is used, which is described in FIGS. 2 to 4.

2, a converging lens 2 focuses parallel light 4 into a focal point 5. This resulting focal point 5 is fed into a light guide 6 in order to transport it. When leaving the light guide 6, the light emerges conically from the light guide 6. With the aid of a converging lens (for example a Cartesian oval) 2, the focal point 5 originally exiting at the light guide 6 can be reproduced again into a focal point 5a.

This is technically not a problem and is state of the art. Now, not only a focal point 5 is fed into a light guide 6 according to FIG. 3, but several foci 5 are fed into the associated light guide 6. The individual light guides 6 are joined together in Fig. 3 with their converging lenses 2 to form a circle, as shown in Fig. 4. In this arrangement, 37 converging lenses 2 are joined together to form a circular hexagon. Subsequently, in FIG. 5, the optical axis of each individual lens 2 is changed so that the individual focal points 5 can be combined via a lens arrangement 1 in a new common focal point 7.

This newly formed common focal point 7 has the same physical properties as a conventional focal point 5.

Now, starting from FIG. 5, as shown in FIG. 6, this newly formed focal point 7 can also be fed into a light guide 6. Thus, in this case, the number of original 37 optical fibers 6 has been reduced to one optical fiber 6a. Of course, this also means an area reduction of 1/37. The focused focus 7 from the light guide 6a could now again be the starting position of a new focus. Since this is a reproduction with recurring initial situation, the process is theoretically unlimited feasible.

Of course, the lens assembly 1 presented herein may have different numbers, sizes, and shapes of individual segments (lens or lens group), and the angle of curvature may vary individually depending on the application. This makes it possible to produce the focal point 7 in different ways.

FIG. 7 shows a closed form of the lens arrangement 1. That is, the lens assembly 1 forms a ring having a focal point 7 of 360 °. The lens assembly 1 itself constitutes a closed unit and therefore may be part of a closed system. Since it forms a cavity in a closed system, it is conceivable a medium z. B. Injecting water into the center of the focal point 7 at high speed, which would expand explosively by the high temperatures. The high-energy steam jet could then be used for energy conversion. In order to emphasize the difference between a lens arrangement 2 existing in the current state of the art (FIGS. 2 to 4) and the lens arrangement 1 presented here, a mathematical comparison of the energy concentration is used.

A conventional lens array 2 attains a ratio of the light concentration from the diameter area of a lens to the focal point area of about 1: 800. Here ends the possibility to focus the light 4.

As a direct comparison, the presented lens system 1 in Fig. 8 is now used. In this example, the light penetrates four lens arrays altogether, which is technically not a problem. The first lens arrangement 2 corresponds to normal converging lenses which focus the light 4 into a focal point 5. The second lens arrangement 1 consists of 37 individual segments of lenses. This focuses the individual focal points 5 to a new focal point 7 by a factor of 37. The third lens arrangement 1 also focuses by the factor 37 now the respective focal points 7 to a single new focal point 7. The fourth lens arrangement 1 consists of an annular arrangement with the factor 481 (consisting of 481 individual segments of lenses). It focuses all the focal points 7 from the third lens arrangement 1 into a central focal point 7 a in the middle of the fourth lens arrangement 1.

The following statement thus results in FIG. 8: The first lens system 2 has a light concentration of 1: 800, the second lens system 1 has 37 individual elements, the third lens system 1 also has 37 individual elements and the fourth lens system 1 has 481 individual elements.

Now the following mathematical equation results in this example. 1. Lensensyst. 2. Lensens. 3. Lensens. 4. Lens system 1: 800 x 37 x 37 x 481 = 1: 526,791,200

The light output area in front of the first lens system 2 is reduced in the newly formed focal point 7a by a factor of 526,791,200 with a constant amount of light. If one were to extend this test arrangement only by a further lens arrangement 1 with the factor 37, the light output area in the focal point 7a decreases to 1: 19,491,274,000.

Physically, this poses no problem at all, because the light penetrates only four or five lens arrays 1, 2.

The starting position for the lens arrangement 1 does not necessarily have to be a lens arrangement 2 as previously described, which focuses parallel light 4 into a focal point 5. If one leaves these away, it is possible to focus light 3 from the most different directions into a new focal point 7.

In the example according to FIG. 9, light beams 3 impinge on the light guides 6 from the most different directions. These receive the light 3 and transport it to a lens arrangement 1, where the light beams emerging from the individual light guides 6 are focused into a common point 7. From now on there is again a starting situation as already described in FIG. 6 and the light 3 can now be theoretically focused indefinitely with other focal points 7.

This clarifies that in Fig. 6 only in the initial situation parallel light 4 is present. Further focusing of the focal points 5 by the lens arrangement 1 already takes place under nonparallel light conditions 3.

Since different combination possibilities are now available to produce a focal point 7, it is also possible to convert already highly concentrated focused light 3, as shown in FIG. 9, into parallel light 4. For this purpose, the device requires a further lens arrangement 2 in order to convert the light beams 3 which run to the newly formed focal point 7 or which have already passed through the focal point 7, into parallel light beams 4.

With the aid of the lens arrangement 1, a focal point 7 can now be composed of different light sources. It is therefore also possible to put light together according to certain desired criteria. So it is z. B. possible to combine sunlight with artificial light individually in a focal point 7 or parallel light 4. There is also the possibility kθit, not only to filter certain light properties out of the light as before, but to incorporate specifically desired properties.

Since the creation of a focal point 5 according to the current state of the art based only on the basis of parallel light beams 4 and focusing of light 3 in an absolutely diffuse light space 8 is not possible, in Fig. 10a - 11 a theoretical proof of the technical Possibility of light bundling in a diffuse light space 8 are provided by means of the lens assembly 1 presented here.

For this purpose, a completely closed lens arrangement 1 in spherical form is required in FIG. 10a (only a section through the sphere is shown). The latter can focus a focal point 7b in the center of the lens arrangement 1 in an absolutely diffuse light space 8 (FIG. 11). The prerequisite for this is that the focal length from the focal point 5 in front of the lens is smaller than the reproduced focal point 7 behind the lens (FIG. 10b).

Due to the possibility of an extremely high concentration of light, the fusion of different locations with one another is possible, as can be seen in FIG. 12. The individual transport via light guide 6 or the transport without medium (light could be sent directly to a desired destination, which could reduce the transport costs) is the prerequisite to make light itself a marketable commodity.

Finally, the lens arrangement 1 belongs to the group of converging lenses 2, which makes the use of such a lens arrangement 1 in the optical region conceivable. So it is conceivable that lens telescopes no longer consist of a large and difficult-to-manufacture single lens but of several lenses that are assembled into a lens assembly 1. [REFERENCE LIST]
