Description

Side solar concentrator

The present invention relates to a solar concentrator, and more particularly, the solar light incident on the front surface of a flat plate type and a large area is finally focused on the side of the flat plate to maximize the efficiency of condensing solar energy and at the same time generate / collect / condense. It is a solar photovoltaic concentrator that can be used for all, improves space utilization, and can significantly reduce manufacturing costs.

In general, the method using solar energy absorbs solar heat by using solar power generation, solar heat collecting pipe or heat collecting plate that generates electricity by using solar cells, and solar heat collecting, lighting or plant growth that uses it for hot water production or heating. Alternatively, there is a solar natural light, such as natural light using a solar natural light module or a reflector for use in the photocatalyst.

As is well known, in order to make full use of solar energy, it is necessary to efficiently collect solar light and various solar light concentrating devices are used for this purpose. The light intensity of the light concentrating device is used for photovoltaic power generation, solar heat collection, solar natural light, etc. Whatever the method, it is directly related to solar energy efficiency.

Photovoltaic concentrators include point-focus dish types, point-focus Fresnel lens types, linear-focus Fresnel lens types, and Helios. Heterostat type (heliostat type), Gregorian / Casegrain condensing system, condensing using a holographic prism sheet and the like and countless other various methods are known.

In general, the solar light collecting device requires a variety of basic conditions according to the above-described respective usage methods, which causes a lot of overlapping investment. For example, the holographic prism sheet, which is a recently used technical alternative to increase the power generation efficiency of the solar cell and reduce the area of the solar cell, may be adopted, but it is difficult in natural light of optical cables. This is because the constraint that the incoming sunlight must be parallel. As another example, in the photovoltaic power generation, the infrared rays included in the solar light, that is, heat is a factor that reduces power generation efficiency, and when the plastic optical cable is used as the optical cable natural light transmission means, heat due to high concentration is a problem. For solar collection, however, heat is a gain requirement, unlike the previous two examples. As such, since the light collecting device is designed differently according to different application methods, it is difficult to use them in common. Therefore, it is difficult to utilize a single solar concentrator in various applications at once, and in fact, such a solar concentrator has been difficult to find.

In addition, the above-described conventional solar light concentrator is generally inevitable to increase the size of the solar light concentrator structure in order to increase the amount of power generation / solar heat collection / photovoltaic natural light of the photovoltaic power generation facilities, the cost or structure in large-scale manufacturing As a result, many constraints arise, which makes it very difficult to expect economical investment.

However, since the previous application was an improved alternative for the foundation to increase the light collecting efficiency of the solar light collecting device by allowing the incident light to be incident in parallel, it should be able to be used simultaneously for various applications in the solar light collecting device part. There is still an urgent need for technological alternatives that significantly reduce costs, are easy to enlarge, can be applied to small spaces, and above all, significantly lower costs and increase the economics for investment for many consumers.

You will know.

1 is an exemplary view for explaining a basic concept of a side solar light collector according to the present invention. As shown in FIG. 1, the side solar light collector 10 according to the present invention includes a light collecting unit 20 in which a plurality of unit light collecting modules 21 are formed in a one-dimensional array, and each unit light collecting module 21. Reflecting portion 31 which collects a plurality of focused solar light incident from the light to the side again and condensing is composed of a side light-converging member 30 formed in a stepwise manner.

At this time, the unit condensing module 21 focuses the solar light 11 in the form of incident parallel light primarily and side-condensed through the linear back light guide part 22 formed at the lower end (see FIG. 2 for a detailed structure). The primary focused solar light 12 is transmitted to the reflector 31 of the member 30.

The reflector 31 is one-to-one corresponded to each of the unit light collecting modules 21 in the longitudinal direction, and receives the light emitted from the unit light collecting module 21 to be folded at a predetermined angle to reflect to the side, and the reflected sun Stepped multistage so that light is not obstructed in the middle of advancing to the side.

According to the present invention, the solar light 11 having a parallel light form incident on the front side of the light collecting part 20 having a large area is first collected by each unit light collecting module 21 and multi-stage on the side light collecting member 30. Since the plurality of reflecting portions 31 are formed to induce and reflect the focused solar light transmitted from all the unit light collecting modules 21 to the side, the solar cells (not shown) on the side of the side light collecting member 30 to be collected. Can be used to significantly reduce the area of the solar cell, and linear condensing optics can be used even when the solar natural light module (not shown) is installed on the side where light is finally incident on the optical cable. This reduces manufacturing costs and significantly reduces operating space.

Hereinafter, in various embodiments of the present disclosure described below, the side solar collector 10 automatically adjusts the azimuth and elevation angles of the sun according to the change of the sun position by a sun tracker (not shown). It can be configured, which will be easily implemented by those skilled in the art through the rotation driving means, inclination angle adjusting means, etc. disclosed in the relevant field before the present invention, and also described in detail in the first application 1, 2 will be omitted for the description thereof. .

In addition, according to various embodiments of the present disclosure described below, it is assumed that sunlight incident on the upper surface of the side solar light collector 10 is direct sunlight in the form of parallel light, and the unit light collecting module 21 is continuously arranged in one dimension. However, the light collecting unit 21 may be refracted at a predetermined angle and incident on the unit light collecting module 21, and in this case, a predetermined interval may be formed between the light collecting units 21 arranged in a straight line. . In addition, it is assumed that the refractive indexes of the materials used for the light collecting unit 20 and the side light collecting member 30 are constant with respect to incident sunlight.

(First embodiment)

2 is a cross-sectional view illustrating a structure of a side solar light collector according to a first embodiment of the present invention, which includes a side light collecting member using a transparent material and a light collecting unit using a unit linear convex condenser lens.

As shown in FIG. 2, the solar light collector 10a ′ according to the first embodiment of the present invention is made of a light collecting part 20a and a transparent material that receives light from the light collecting part 20a and condenses it to the side. Side light collecting member 30 '.

In this case, the light collecting part 20a is formed in an array of a plurality of unit linear convex condensing lenses 21a having a round cross-section convex on an upper surface, and a predetermined position corresponding to the unit linear convex condensing lens 21a on a lower surface thereof. The linear back light guide 22 is formed, and the linear back light guide 22 may be formed in a protruding shape or a recessed groove. At this time, when the linear back light guide portion 22 does not protrude and the groove is dug inwardly, the light that is not vertically incident is totally reflected when it is incident above the threshold when light is incident from the dense medium into the small medium. Although this may be lost, when the linear back light guide 22 is formed as a protrusion, the reflective layer may be coated on the surface of the linear back light guide 22, thereby minimizing light loss.

Here, in the first embodiment, the sunlight 11 is incident 11 perpendicularly to the upper surface of the unit linear convex condenser lens 21a. Further, as shown in FIG. 2B, the linear back light guide 22 blocks and passes through the refracted wandering sunlight that is likely to enter the inside of the linear back light guide 22. An elevation reflection layer 221 is formed so as not to be emitted to the elevation except the bottom of the focused light, and a bottom reflection layer 222 may be formed on the condenser 20a except for the bottom of each linear back light guide 22. When the reflective layer is formed, light does not flow from the lower portion, and the rear lower portion 220 is formed to be transparent to allow light to pass therethrough. In this case, the linear back light guide 22 is preferably formed to have a size of about microscopic.

In addition, the linear back light guide part 22 is formed such that the optical focus F1 of the unit linear convex condenser lens 21a is positioned inside or under the rear surface 220, and is incident on the unit linear convex condenser lens 21a. Sunlight forms an elongated linear focal line in the longitudinal direction inside the linear back light guide 22 formed in the longitudinal direction.

Therefore, the sunlight incident on the light collecting part 20a having a large area is divided by each unit linear convex condenser lens 21a and condensed, respectively, and is focused on a focal line formed per unit linear convex condenser lens 21a.

The side light collecting member 30 'is made of a transparent material, but the reflecting portion 31 is formed in multiple stages in the form of a stairway located upside down in space, and the reflecting portion 31 is formed at an angle at a predetermined angle and a reflective layer is formed. In the first embodiment of the present invention, the angle is 45 °.

In addition, the upper surface reflection layer 33 and the lower surface reflection layer 34 may be formed on the upper side of the side light collecting member 30 'except for the light incident portion. Optically transparent materials such as glass, pyrex, quartz glass are preferred, and it is preferable to select the materials according to the condensing purpose of the side solar light collector according to the present invention. In the first embodiment of the present invention is a UV-400 acrylic sheet using a monomer for UV-blocking plastic lens, and since the plastic is usually yellowed by ultraviolet light, UV solution to solve the yellowing problem caused by solar UV The coating or the sunscreen monomer as described above may be used to ensure weather resistance, and the matter regarding the weatherability enhancement by the solar UV is easily implemented by those skilled in the art, and thus description thereof will be omitted.

Therefore, the sunlight 11 incident on the unit linear convex condensing lens 21a gathers at the focal point F1 formed by the unit linear convex condensing lens 21a and reaches the reflecting section 31. In accordance with the principle of total reflection between the medium (air) in the 400 acrylic sheet), the direction of the side light collecting member 30 is changed as shown in FIG.

Herein, total reflection refers to a phenomenon in which light is reflected, rather than refracted, when light enters a dense medium from a dense medium. In particular, when the angle of refraction is 90 °, the angle of incidence is a critical angle θ. When the incident angle is larger than the critical angle, total reflection occurs, and when compared with the refractive index n, n = 1 / sinθ has a relationship.

At this time, each of the sunlight focused from the unit linear convex condenser lens 21a and turned to the side is mostly in parallel light form by the reflector 31 formed in multiple stages in the side condensing member 30 '. By being reflected, it is possible to advance in parallel to the side without being disturbed by other reflectors 31, and the refracted light 12 of the diverted focused light 12 that is not converted in parallel at right angles in the dense medium until reaching the side By the same total reflection principle to a small medium, the light is efficiently focused on the side surface.

Typically, acrylic plastics used in optical glass or plastic optical cables have a light attenuation of less than 2 to 5% per meter, so almost all of the light is delivered to the side and condensed, maximizing condensing efficiency.

In addition, even if the refractive index of the side light collecting member 30 ′ is a transparent material having a larger refractive index than air, a predetermined reflective material may be coated on the outer side of the reflector 31 when it is difficult to apply the above-described total reflection principle according to the material characteristics. have. Here, the predetermined reflective material means a metal material having a reflectance of 90% or more, and aluminum, silver, gold, nickel, and the like may be used. In the present invention, it is preferable to use a low-cost aluminum having a reflectance of 90% or more as a reflective material, and reflect the front reflection layer 221, the bottom reflection layer 222, the top reflection layer 33, and the bottom reflection reflection layer 34. The same applies to material coatings.

On the other hand, although not shown, the unit linear convex condensing lens 21a is a small convex condensing lens for concentrating sunlight incident on a small circular plane or a quadrangular plane at one focal point when viewed from an image side where sunlight is vertically incident. May be arranged in a straight line in the longitudinal direction, and a gap may be formed between the “point focus” small convex condenser lenses (not shown).

In addition, the side solar light collector 10a 'of the first embodiment may be manufactured using a conventional lithography process, and the light collecting unit 20a and the side light collecting member 30' may be separately manufactured and assembled.

In this case, an upper side of the side light collecting member 30 ′ may further include a light guide (not shown) corresponding to the linear rear light guide 22. The light guide (not shown) is formed by combining an optical cable linear array, a linear fiber optic, and an elongated rod lens with the linear back light guide part 22 so that parallel light is irradiated to the reflector 31. desirable.

In addition, in order to efficiently reflect the sunlight 11 sideways in the form of parallel light without loss, the primary focused sunlight reaching the reflector 31 should be parallel light as much as possible, and the narrower the width, the more effective. The linear back light guide 22 or the light guide (not shown) plays a role so that the primary focused solar light is incident in parallel and at the same time reduces the area of contact with the reflector 31. It is possible to reduce the thickness of the side light collecting member 30 ', and as the contact area decreases, the number of parallel light reflecting portions 31 is formed in multiple stages on the side light collecting member 30' of the same thickness. Since the number of arrays of the unit linear convex condenser lens 21a can be increased, the radius of curvature of the unit linear convex condenser lens 21a can be reduced, and as a result, the focal length can be reduced and the overall side solar condenser can be reduced. It is possible to significantly reduce the thickness of the madness 10a ', which is one of the characteristics of the present invention.
