1 is an exemplary view for explaining the basic concept of the prism wave guide according to the present invention
Figure 2 is a longitudinal cross-sectional view of the prism wave guide according to the present invention

Hereinafter, a prism wave guide according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1 and 2, the prism wave guide 1 according to the present invention, the two rectangular prisms are combined to have a 'V' shape to form a pair, a plurality of pairs are arranged on a straight line An upper prism 32a having a light entering part 31 through which light enters or exits a 'V' lower end point where the pair of right angle prism abuts; Lower prisms 32b arranged to be in close contact with each other or formed integrally with a double size or two of the right-angle prism constituting the upper prism 32a at intervals below the upper prism 32a, and arranged in an inverted triangle shape. And a child prism groove 32c is formed in each of the lower prisms 32b to a specific depth so that light incident inwardly through the light exiting portion 31 is totally reflected laterally at a specific height, so that the upper prism 32a is formed. ) And the light that is totally internally reflected by the lower prism 32b and guided to the side or is incident from the side to the inside is guided by total internal reflection within the upper prism 32a and the lower prism 32b to emit light 31 Is emitted.

More specifically, as shown in FIG. 2, the prism wave guide 1 has a plurality of upper prisms 32a formed with light entering and exiting portions 31 formed at a lower end of a 'V' contacted by a pair of rectangular prisms. Or, a plurality of spaced apart by a predetermined distance is formed, the lower prism (32b) is formed to correspond to the lower end, respectively, with a size of two or two times the right angle prism constituting the upper prism (32a) at a lower interval. The lower prism (32b) is formed in close contact or formed integrally and arranged to correspond in an inverted triangle shape, the lower prism (to allow the light incident to the inside through the light entering and exiting part 31 is totally reflected to the side at a specific height ( 32b) Child prism grooves 32c are formed in each of a specific depth.

At this time, when the shape of the prism wave guide 1 includes the upper prism 32a and the child prism groove 32c space, when the lower prism 32b is arranged closely in succession, the longitudinal cross section (i-line) ) Is like a sheet of 'V' shape, which is not shown, but when not spaced apart by a certain distance, it is like a 'V' shaped cross section with a certain distance on a flat sheet of a certain thickness. It is formed of solid body.

At this time, the lower prism 32b is to form two child prisms 32b1 and 32b2 by the formed child prism grooves 32c, and the depth of the child prism grooves 32c has a depth of each lower prism 32b. The depth is differently formed so as to be stepped at), and the light incident through the light entering part 31 is totally reflected at a specific height by the child prisms 32b1 and 32b2 to move laterally or the light incident from the side upside down is the child prism It is formed so as to be emitted to the light input / output part 31 by the 32b1 and 32b2.

The child prism groove 32c may be formed at the center of the light exit part 31 so that the light incident through the light exit part 31 may be divided by the child prisms 32b1 and 32b2. Will do.

In such a configuration and structure, each prism adjacent to the left and right corresponding to each other acts to totally reflect the incident light to move to the side, and each prism corresponding to the up and down hinders the progress of the light by the prism while exchanging the incident light up and down. And a plurality of these are formed in an arrangement to finally guide the light to the side.

In addition, the prism wave guide 1 formed long in the longitudinal direction can be used as a substitute for the elongated prism wave guide 1, for example, a horizontal blind slat, which is very rigid in bending in the longitudinal direction. Since the length of 2 to 3 meters and is mounted on both sides of the structure is not a concave-convex shape can be bent, but the prism wave guide (1) of the present invention is suitable to substitute because it has a very strong structure to bend. .

In addition, although not shown, the upper prism 32a and the lower prism 32b are formed on separate sheets, respectively, and manufactured separately, and then combined and integrated with each other, or the first prism 32a and the lower prism 32b are first manufactured. It is assumed that a hollow can be formed between and the refractive index of the material used for the prism wave guide 1 is constant with respect to the incident light.

As described above, when the upper prism 32a and the lower prism 32b are separately manufactured and combined, and the focused light incident on the light exiting part 31 is point light, the light exiting part 31 and Between the child prisms 32b1 and 32b2, the light is focused narrowly in the longitudinal cross section, but the light incident on the flat cross section (the plane cut along the j-line) is incident on the light cross-section through the light entry part 31 formed in the longitudinal direction along the flat cross section. It may further include a unit linear collimator 22 formed on a flat cross-section that can be incident to the light received perpendicular to the lower prism (32b).

On the other hand, one light entering and exiting part 31 is formed in the longitudinal direction (direction cut along the j-line) at the 'V' lower apex to which a pair of right angle prism of the upper prism 32a abuts, the longitudinal section is rectangular shape The bottom horizontal and left and right vertical surfaces are formed to be flat to transmit light, and preferably have an antireflective coating or an antireflective structure, and have a small right angle prism in the form of an inverted triangle in order to totally reflect incident light in the vertical direction. It can be formed as.

Accordingly, the parallel light incident simultaneously on the plurality of light exit portions 31 is condensed laterally by the prism wave guide 1, that is, the light 11b simultaneously introduced into one light exit portion 31 is unique. Advancing along the path (optical channel) and the incoming light 11b has a plurality of different optical channels, to the upper prism 32a and the lower prism 32b, and the stepped child prisms 32b1 and 32b2. Is totally reflected and gradually induced laterally.

At this time, total reflection cannot occur in the light entering part 31 formed on a portion of the upper surface of the upper prism 32a, but the first incident light to the light entering part 31 interacts with the stepped child prisms 32b1 and 32b2. Since the light is totally reflected laterally through one of the left and right light channels independently formed by the light beams, the light incident on all the light channels does not overlap with another light channel, that is, the light channel introduced into the other light exiting part 31. Since it moves forward to the side as shown in (a) and the pair of right-angle prism of the upper prism 32a is located at the bottom vertex of the 'V', the 'V' groove space is utilized when combined with the optical unit 2 to be described below. There is an advantage that can be (see FIG. 2b).

The light 11b introduced into the light entering and exiting part 31 is advanced by the total reflection principle by the upper prism 32a and the lower prism 32b in multiple stages, and total reflection is a small medium in a light dense medium. It refers to a phenomenon that the light is not refracted when the incident light is reflected and proceeds, and since it will be easily understood by those skilled in the art, the detailed description will be omitted, and the upper prism 32a continuously formed inside the prism wave guide 1 and Since the lower prism 32b is mostly reflected in the form of parallel light, the upper prism 32a and the lower prism 32b can be advanced to the side without being disturbed and are efficiently focused on the side surface.

Meanwhile, the prism wave guide 1 is made of a transparent material, but the upper prism 32a and the lower prism 32b and the child prism 32b1 and 32b2 are formed at an angle at a predetermined angle with the surface (beveled surface). And a material layer having a low light refractive index may be further formed so that the total reflection principle from dense to small media may be applied even if it is not air. In the present embodiment, the total prism 32a and the bottom prism ( 32b) is an air (air cladding) is a small medium in contact with the oblique surface and can be easily understood by those skilled in the art will be omitted further detailed description of the structure for forming the total reflection of light.

In addition, the material of the prism wave guide (1), such as acrylic, polycarbonate, heat-resistant polyimide and the like having a good optical refractive index and optical such as transparent glass, gorilla glass, pyrex, quartz glass, silicon of various compositions A transparent material is preferable, and it is preferable to select a material according to the light use of the prism wave guide 1 according to the present invention. In this embodiment is a UV-400 acrylic sheet using a monomer for UV-blocking plastic lenses, since the plastic is usually yellowing by the ultraviolet light, UV coating or UV solution to solve the yellowing problem caused by solar UV The blocking monomer may be used to ensure weather resistance, and the matter regarding the improvement of weather resistance by solar UV will be easily implemented by those skilled in the art, and thus description thereof will be omitted.

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

In addition, even if the prism wave guide 1 is a transparent material, if it is difficult to apply the above-mentioned principle of total reflection according to the material property, a predetermined reflective material may be coated on the outer sides of the upper prism 32a and the lower prism 32b. have. Here, the predetermined reflecting material means a metal material having a reflectance of 90% or more, and aluminum, silver, gold, nickel, a stainless steel sheet, or the like may be used.

In addition, the prism wave guide 1 of one embodiment of the present invention can be produced using a conventional lithography process.

In addition, in order to efficiently reflect the light 11b laterally in the form of parallel light without loss, the light reaching the light exiting part 31 should be parallel light as much as possible, and the narrower the width, the more effective the light is. This is because the smaller the area of the light incident to the light entering and exiting portion 31 and the smaller the area of contact with the light entering and exiting portion 31, the more the optical channels.

On the other hand, the prism wave guide 1 of the present invention, although not shown, by placing the LED light source on the side, the high-density light is totally reflected after the incident on the side for each channel described above through the prism prism wave guide 1, It can be split through the entrance and exit portion 31 and emitted to the front side, wherein it is preferable to convert the light emitted from the LED between the LED and the prism wave guide 1 into parallel light. Once parallel light is incident on the side of the prism wave guide 1, it is easily understood by those skilled in the art that the light advancing through the light channel is emitted to the front through the light entrance part 31, which is described above. Since it corresponds to the front diffused light which is the opposite concept to the condensing and is also described in the prior application, a detailed description thereof will be omitted.

When light is incident on the prism wave guide 1 uniformly, such as solar light, the density of the light emitted through the light exiting part 31 is equal to the light attenuation ratio of the material of the prism wave guide 1. , Except that the attenuation given by the light attenuation within the light travel distance according to the spaced apart position of the light entering and exiting part 31 on the side has the effect of being uniformly distributed.

In addition, when the LED light source is additionally disposed on the other surface where the LED light source is disposed to form the unused light channel and the light exit part 31, more uniform light may be emitted to the front through the light exit part 31. In addition, since it will be apparent to those skilled in the art, a detailed description thereof will be omitted. Thus, the light may be used as a light collector, or vice versa, depending on the position of incidence of the light of the prism wave guide 1 according to the present invention. In addition, the present invention can be applied to a diffusion lens or a light guide plate by further expanding the field, which is one of the important features of the present invention.

On the other hand, as shown in (b) of FIG. 2, the front of the prism wave guide 1 according to the present invention focuses light reaching parallel light 11a on the front surface and emits a narrow focused parallel light 11b. The optical unit 2 may further include an optical unit 2 that is incident to the light exit unit 31 or received from a light source on the side to scatter light emitted through the light exit unit 31.

The optical unit 2 includes a plurality of unit optical modules 20 arranged in one dimension, and the unit optical module 20 converges or receives focused light 11a that is incident on the front surface. ) And the condensed light exiting from the unit linear collecting and scattering member 21 again matches the optical axis of the unit linear and scattering member 21 and the unit linear collecting and scattering member 21. Branch light exits toward the light exit portion 31 of the prism wave guide 1 in the form of linear parallel light, or transmits high-density light from the LED light source located on the side of the prism wave guide 1 through the light exit portion 31. It is composed of a unit linear collimator 22 that is correspondingly provided so as to emit through the unit linear collecting and scattering member 21 to finally diffuse the unit linear collecting and scattering member 21.

In addition, the unit linear collimator 22 may be integrally formed in the light entering and exiting part 31, and in this case, only the unit linear collecting and scattering member 21 described above may be added, and the optical axis of the unit linear collecting and scattering member 21 may be used. It is desirable to match one-to-one with one another.

On the other hand, the unit optical module 20 may be used as a unit linear collimating light scattering member 21, a unit linear Freonnel lens, a unit linear collimator 22 may be a unit linear collimating convex lens.

In addition, the unit linear collimator 22 may be implemented in various forms instead of the unit linear collimating convex lens. For example, although not shown, a unit linear collimating Freonel lens, a unit linear collimating concave lens, a linear collimating green lens, and a linear collimating concave Lens, long collimation optical fiber, linear collimation fiber optical taper, linear collimation cylinder lens, collimation green lens, collimation convex lens, collimation concave lens, collimation fiber / ball lens and collimation fiber array can be selected. In addition, a number of collimation optical systems are well known and detailed descriptions will be omitted since reference may be made to a prior application.

In fact, as an embodiment of the unit linear collection and scattering member 21, the unit linear Freonel lens and the unit linear collimating convex lens positioned behind the focal point can be easily understood by those skilled in the art as a basic optical system configuration constituting the Kepler telescope. Using the unit linear collimating concave lens positioned in front of the focal point instead of the linear collimating convex lens, this is the basic optical configuration of the Galileo telescope, and instead of the unit linear convex lens, the unit linear convex lens, the unit linear aspherical lens, the unit linear green lens, Unit linear fiber optic taper (not shown), unit linear caseegrain optical mirror with rear window, unit linear Gregorian optical mirror with rear window, unit convex lens / unit Freonel lens / unit aspherical lens / diffuse green lens / unit fiber Optic taper / unit Gregorian optical mirror / unit caseegrain optical mirror each Linear arrays may be used, and many others are known, and additional descriptions thereof will be omitted since those skilled in the art can easily practice and refer to prior applications.

In addition, the unit linear convex lens, the unit freonel lens, the unit aspherical lens, the divergent green lens, the unit fiber optic taper, the unit Gregorian optical mirror, and the unit casee grain optical mirror of each of the unit linear collecting and scattering members 21 are included. In this case, since the focused light 11b emitted to the unit linear collimator 22 corresponding thereto has a dot shape, it is well known to condense the light to the side surface simply by forming a light input and output part 31 having a spot size at the corresponding position. In this case, the light condensed to the side is not condensed linear linear light, but the condensed light 11b having a predetermined distance apart is condensed to the side in a linear arrangement.

Accordingly, when such a structure is used for solar condensation, which is a kind of light, it is not necessary to install a solar cell so as to correspond to one unit convex lens (or freonel lens) that focuses the sunlight incident on the front side, and has a point shape. Installing a high-efficiency solar cell at a highly concentrated photovoltaic (11c) location can greatly increase its power generation efficiency, and dramatically reduce the number and required area of solar cells. It can be used at the same time, and if it includes an electric rotating mirror at the end, it can use natural light and high efficiency solar cell selectively, and it is very convenient and applicable. It is an innovative structure that can be used at the same time, which will be easily understood by those skilled in the art.

In addition, the arrangement of the above-described various types of unit linear collection and scattering member 21 is preceded. Not only can the condensing part 2 formed on the back side be used, but also the unit linear collimator 22 on the front side. It can be cross-formed on the back side, and the unit linear collector.The light collecting member linear concave mirror as the light scattering member 21, in principle, the prism wave guide 1 should be disposed on the front, so the upper prism 32a and the lower prism 32b. ) Can not be used because sunlight is not incident in parallel to the concave mirror, but can be used for diffused light.

In addition, the unit linear collector and the light scattering member 21 and the unit linear collimator 22 may be solid bodies formed integrally, and when each of them is manufactured independently, a hollow may be formed therebetween, and the unit linear collimator 22 may be It may be integrally formed on the top of the light entering and exiting part 31, and other condensing lenses and optical mirrors exemplified above may be equally applied.

As such, one embodiment of the present invention described above should not be construed as limiting the technical spirit of the present invention. In addition, the accompanying drawings are only described to more easily disclose the contents of the present invention, the scope of the present invention is not limited to the scope of the accompanying drawings, the protection scope of the present invention by the matter described in the claims Only limited, and those skilled in the art to which the present invention pertains can change and change the technical idea of the present invention in various forms. Therefore, such improvements and modifications will fall within the protection scope of the present invention, as will be apparent to those skilled in the art.
