Definitions

• the invention relates to a textured transparent plate whose texture improves the light transmission through said plate.
• the plate may advantageously be placed between a light source and a photovoltaic cell, so as to increase the light intensity transmitted to the cell. More generally, the plate increases the transmission towards an element juxtaposed to said plate and having a refractive index greater than that of the material of which the plate is made up.
• textures of the pyramid or prism type on the surface of a transparent plate can improve the light transmission of the plate.
• the patterns may be asymmetrical so as to better capture the light when the incident rays are not exactly perpendicular to the plate, which is in fact the most frequent case.
• These asymmetrical patterns still contain a plan of symmetry for the pattern, but usually do not contain two orthogonal planes of symmetry between them. Generally, the plane of symmetry is perpendicular to the general plane of the plate.
• the invention relates first of all to a plate made of a transparent material comprising on its surface a texture comprising at least one raised or recessed relief pattern, said pattern comprising a first face and a second face that are not parallel to each other, the lines to be the base of these faces being parallel, said first face forming with the general plane of the plate an angle greater than the angle formed by said second face with the general plane of the plate, the angles considered being those inside the material if the pattern is protruding, or those outside the material if the pattern is recessed.
• the plate comprises on its surface a plurality of said pattern to improve the light transmission through the plate.
• the "first face” has a larger angle with the general plane of the plate than does the "second face". Thanks to this particular geometry, and if the incident light rays do not always strike the plate perpendicularly to it, the plate can collect more light, if its orientation is judiciously chosen.
• the patterns may appear hollow in the plate or may instead emerge from the plate (that is to say appear protruding or protruding).
• the angles of the faces that are taken into consideration are those inside the material. If the pattern is intaglio, the angles of the faces that are taken into consideration are those outside the material. If the pattern is recessed, the two faces generally meet at a point or line located most internally in the plate. In this case, the base of the pattern is located most externally with respect to the plate. The intersection of each of the faces (the first on the one hand and the second on the other) with the base of the pattern defines a line, the two lines thus defined (one line per face) being parallel. These lines can be straight or curved depending on the pattern.
• the two faces generally meet at a point or line located most externally with respect to the plate.
• the base of the pattern is located most internally with respect to the plate.
• the intersection of each of the faces (the first on the one hand and the second on the other) with the base of the pattern defines a line, the two lines thus defined (one line per face) being parallel.
• These lines can be straight or curved depending on the pattern.
• the two faces are not parallel to each other, but they can each contain an edge or baseline of the pattern (usually a straight line, but which can also be a curve) parallel to an edge or baseline of the pattern (usually a straight line but it can also be a curve) contained in the other face, these two edges or baselines being otherwise parallel to the general plane of the plate.
• the two faces form an angle between them, the bisector of which will be considered (dividing the said angle into two equal half-angles).
• the plate is oriented as much as possible so that the direction of incident light rays is parallel to this bisector.
• the angle can be 35 ° in Paris (France).
• the invention also relates to a wall comprising a plate according to the invention, in particular a vertical wall.
• the invention also relates to an anti-noise wall comprising such a wall.
• the two faces at the origin of the invention are generally smooth, in particular by observation with the naked eye. They can be flat, especially if they are part of a prism or a pyramid. However, they can also be curved.
• a prism has two main faces joining (or intersecting) in one line.
• a pyramid according to the invention preferably comprises four faces, the base of said pyramid forming a square or a rectangle or a rhombus. The pyramid may also comprise more than four faces, for example six faces.
• a plate may be described comprising on its surface a plurality of prism patterns. Such patterns are shown in Figure 1b).
• Figure 1 a shows the prism patterns of the prior art, which are symmetrical with respect to plane 1 and plane 58 which are both perpendicular to each other and perpendicular to the general plane 2 of the plate.
• the plane 1 passes through the outermost line 3 with respect to the general plane of the plate.
• This line 3 is at the intersection of the two faces 4 and 5, these two faces forming the same angle alpha with the general plane 2 of the plate.
• each pattern in the form of a protruding prism, comprises two faces 6 and 7, smooth and flat, nonparallel to each other, and joining together in a line 8 located at the highest outside the plate, the angle formed by the face 6 with the general plane 2 of the plate being greater than the angle formed by the face 7 with the same plane 2.
• the angles taken into consideration are those at 1 the interior of the plate material because the pattern is protruding.
• the first face 6 contains a line 50 at the base of the pattern (the pattern is here an asymmetric prism), said line being located most internally with respect to the plate.
• the second face 7 contains a line 51 at the base of the pattern, said line being located most internally with respect to the plate.
• the lines 50 and 51 are parallel to each other and parallel to the general plane of the plate.
• This pattern comprises a plane of symmetry 58 perpendicular to the general plane of the plate 2.
• This geometry is advantageous if, for example, the plate is in a vertical position and intended to collect the solar energy to transmit it to a photoelectric cell placed behind it. .
• the light output would be much lower cons if the plate was in the opposite position, that is to say, face 7 above and face 6 below.
• the pitch of the patterns of Figures 1 a) and 1 b) corresponds to the distances 52 ( Figure 1a) and 53 ( Figure 1b).
• the invention can also use patterns of the pyramid type.
• Figure 2b) shows such pyramidal patterns.
• Figure 2a shows the pyramidal patterns according to the prior art. These pyramids (projecting) include two planes of symmetry 1 and 58, orthogonal to each other and perpendicular to the general plane 2 of the plate and passing through the top of the pyramid which is the outermost point of the pattern relative to the general plane of the plaque. The two faces 10 and 1 1 are identical and form the same angle with the general plane of the plate.
• each pattern in the form of a pyramid, comprises two faces 12 and 13, smooth and flat, not parallel to each other, and meeting at a point 14 (vertex) located, at the level of the pattern, the outermost relative to the plate, the angle that forms the face 12 with the general plane 2 of the plate being greater than the angle formed by the face 13 with the same plane 2.
• the first face 12 contains a line 60 at the base of the pattern (the pattern is here an asymmetrical pyramid), said line being located most internally with respect to the plate.
• the second face 13 contains a line 61 at the base of the pattern, said line being located most internally with respect to the plate.
• the lines 60 and 61 are parallel to each other and parallel to the general plane of the plate.
• Each pattern comprises a plane of symmetry 58 perpendicular to the general plane of the plate.
• This geometry is advantageous if, for example, the plate is in a vertical position and intended to collect solar energy to transmit it to a photoelectric cell placed behind it. The light output would be much lower cons if the plate was in the opposite position, that is to say, face 13 above and face 12 below. Indeed, whatever the latitude, the solar rays have a direction closer to the direction of the bisector between the faces 12 and 13 if the face 12 is above.
• the patterns of Figures 2a) and 2b) have two steps, corresponding to distances 54 and 55 (Figure 2a) on the one hand and distances 56 and 57 on the other hand ( Figure 1b).
• FIG. 6a shows prismatic patterns whose two main surfaces 31 and 32 are curved.
• This pattern comprises a plane of symmetry 58.
• These patterns are substantially symmetrical insofar as each bisector 33 contained in a plane parallel to the plane of symmetry 58 is orthogonal to the general plane of the plate 34.
• This type of pattern may be incorporated into a textured surface assembly as shown in Figure 6b). Patterns of the type of Figure 6a) are here juxtaposed with different orientations. With this arrangement, the plate has a uniform aspect in reflection over its entire surface, while collecting the light efficiently.
• each bisector 33 contained in a plane parallel to the plane of symmetry 58 is orthogonal to the general plane of the plate.
• the texture represented in Figure 6c) is in accordance with the invention because one of the faces 41 forms a higher angle with the general plane of the plate than the other face 42.
• These curved prism patterns have baselines 43 and 44 curves . We see that the bisectors are not here orthogonal to the general plane of the plate.
• These deformed patterns (with respect to those of FIG. 6a) can also be incorporated juxtaposed with different orientations on a plate in a manner similar to the representation of FIG. 6b. As can be seen in FIG.
• a pattern corresponds to a set of the 4 prisms of FIG. 6a), said pattern being able to register substantially in a square.
• the pitch of the pattern corresponds to one side of said square. If this plate is placed vertically, it is appropriate that the faces of the type "first face” 41 are preferably placed in the upper position.
• the invention provides its effect (light collection), with an improved aspect in reflection (uniform appearance for an observer looking at the plate with the naked eye a few meters away).
• the light rays have a direction as close as possible to the bisectors between the two faces according to the invention.
• the pattern comprises in all cases a face 15 forming an angle alpha with the general plane 2 of the plate, and a face 16 forming an angle alpha 2 with the general plane 2 of the plate, the angle alpha being greater than the angle alpha2.
• angles were taken within the plate material (alphai and alpha2) and not out of the material angles (alpha4 and alpha ⁇ ).
• the two faces 15 and 16 form an angle at the apex alpha3 having a bisector 19.
• There are two types of light exposures the case of the light rays 17 directly striking the face 16 and not striking directly the face 15, and the case light rays 18 striking both faces and whose direction is parallel to the bisector 19.
• the invention provides its effect in the case of the rays 18. If the light rays were always perpendicular to the general plane of the plate (which does not correspond in fact to no real terrestrial situation), a patterned texture symmetrical would be appropriate.
• the plate can be placed vertically, for example on the surface of a sound barrier, photocells being placed inside said wall to receive solar energy through the plate, the face forming the widest angle with the plate being placed in the upper position, so that solar incident rays preferentially strike this face.
• the invention also functions with recessed patterns, as shown in FIG. 4.
• This representation is valid both for hollow prisms and for pyramids recessed in the plate.
• This pattern comprises a first face 20 forming an alpha angle with the general plane of the plate and a second face 21 forming an angle alpha 2 with the general plane of the plate, the alpha angle being greater than the angle alpha 2.
• the angles outside the material (alphai and alpha2) are taken into account because the pattern is hollow, and not the angles in the material (alpha4 and alpha ⁇ ).
• the best light output is obtained when the incident light rays 22 have a direction parallel to the bisector 23.
• the first face 20 contains a line 70 at the base of the pattern (said base being located externally relative to the plate) and the face 21 contains a line 71 at the base of the pattern, so that the lines 70 and 71 are parallel to each other and parallel to the general plane of the plate, whether the pattern is a prism or a pyramid.
• the ratio between the angle (in degrees) between the first face and the plane of the plate, and the angle (in degrees) between the second face and the plane of the plate, is greater at 1, and generally greater than 1, 1 and may even be greater than 1, 2.
• the angle that forms the face (called "first face") having the largest angle with the plane of the plate can range from 50 to 130 ° and preferably from 70 to 88 °.
• the angle formed by the face (called “second face") having the smallest angle with the plane of the plate can range from 10 to 60 °, and preferably from 20 to 50 °.
• a preferred texture corresponds to the combination of an angle of 85 ° for the first face with an angle of 45 ° for the second face.
• the patterns may be of the type shown in FIG. 5, with an alphai angle greater than 90 ° and an angle alpha2 of less than 45 °. In practice, it is very difficult to produce such a texture by rolling and one would be obliged to realize it to use much more sophisticated techniques such as laser cutting, which is however relatively expensive.
• the alphai angle (the highest angle of the two faces according to the invention with the general plane of the plate) is less than 90 °.
• the rolling technique that can be used to produce the texture according to the invention is in particular explained in application PCT / FR2005 / 050304. It is, of course, very difficult to produce rigorous flat surfaces and very sharp edges by this technique, particularly in view of the small size of the patterns, so that it would not be possible to go beyond the scope of the present invention by rounding a little the faces or vertices or edges of the patterns.
• the plate is made of a transparent material, as clear as possible, such as a mineral glass, or an organic polymer (PMMA, polycarbonate, etc.).
• a transparent material such as a mineral glass, or an organic polymer (PMMA, polycarbonate, etc.).
• the effect of the invention works regardless of the size of the patterns.
• the patterns may for example have one or more steps each ranging from 0.1 to 10 mm, in particular from 1 to 6 mm.
• the step is the periodicity of the parallels at the base of the prisms.
• the pyramids it is the dimension of the base of said pyramids.
• the pyramids preferably have 4 sides. More generally, the pitch characterizes the size of the patterns, or the distance at which they repeat, to the extent that they are joined.
• the plate provides an effect according to the invention since only one pattern according to the invention is present, even if it is mixed with other symmetrical patterns.
• the invention provides more effect if more patterns according to the invention are present and are oriented compatibly. Patterns are compatibly oriented, if their respective "first faces” are oriented in substantially the same way. The orientations of these motifs (in relation to their "first" faces) are not necessarily exactly the same, but they should not be opposed.
• the patterns according to the invention present on the surface of the plate are predominantly oriented (more than 50% of their total number, and preferably more than 70% of their total number) so that all the orthogonal directions the "first faces" of each pattern are contained in the same quarter of space facing the plate.
• the invention also relates to a light capture method comprising the positioning of a plate according to the invention so that the direction of incident light rays is included in said quarter space.
• Figure 7a shows an asymmetrical prism type pattern comprising a "first face” 80 and a "second face” 81. This pattern was placed on the surface of the plate 82 ( Figure 7b)) with different orientations. Patterns 83, 84 and 85 have a compatible orientation because the orthogonal directions (87, 88, 89) at the first faces of these patterns are all included in the quarter space facing the plate corresponding to the hatched volume. On the contrary, the pattern 86 is not compatible with the others because the direction orthogonal to its first surface comes out of the quarter space facing the plate. The patterns 83, 84 and 85 may advantageously receive the light rays included in the quarter hatched space and coming in their direction.
• the surface texture of the plate may consist of the assembly of individual relief patterns, in particular pyramids, said individual patterns being based on one or more basic patterns. but which are distinguished by their depth, their height or the perimeter of their base surface.
• Figure 8 illustrates the shape that can have juxtaposed pyramid bases to eliminate this problem of reflection. This figure shows only the bases of pyramids (4 faces) juxtaposed to show that their baselines form zigzag lines. Thanks to these different bases (diamonds with varying angles from one base to another), the problem of reflection is eliminated.
• the surface texture of the plate may have a three-dimensional surface structure which comprises elements formed on the surface of the substrate and whose extension is essentially longitudinal and is substantially larger. the extension of these elements in the transverse direction, the surface of the substrate generally forming groups of parallel elements whose orientation of the longitudinal extension of the elements is alternated from one group to another. This is particularly the case of the structure of FIG. 6b), if combined with the fact that the curved prisms are according to the invention (FIG. 6c).
• the textured plate according to the invention can be part of a wall, as a vertical wall.
• This wall may contain photoelectric cells for collecting sunlight.
• the plate is located on the side of the wall where the sun is predominant (higher light intensity).
• a plate according to the invention can be placed on both sides, each plate on each side being then equipped with a photovoltaic cell.
• the textured plate can therefore be used in particular to improve the capture of sunlight to increase the luminous flux supplying photocells.
• the plate may in particular be made of glass (refractive index close to 1.5) and the photoelectric cell made of silicon (refractive index greater than 3).
• These photocells can be encapsulated in a polyvinyl butyral resin (PVB) or ethylene-vinyl acetate copolymer (EVA).
• PVB polyvinyl butyral resin
• EVA ethylene-vinyl acetate copolymer
• This encapsulation can in particular be carried out in a known manner by autoclave under hot pressure (melting of the resin) which leads to a resin sheet in which the cells are trapped.
• the textured plate is then juxtaposed to this sheet to capture the light (texture on the side of the ambient air) and deliver it to the cells in the sheet. It is possible to combine all these components in a single step in an autoclave. It is generally sought to avoid the presence of air between the textured plate and the photovoltaic cell. To do this, there is usually always resin (PVB or EVA) between the textured plate and the cell.
• PVB polyvinyl butyral resin
• EVA ethylene-vinyl acetate copolymer
• Such a complex structure can serve both as a solar energy sensor and noise barrier. Its anti-noise efficiency is even better than the resin used is of the "acoustic" type, that is to say, attenuates the noise.
• the textured plate may have a thickness (including relief) greater than 6 mm, or even greater than 8 mm, especially if it must have a better mechanical strength, which is particularly generally the case if it is integrated in a noise barrier.
• the tables below compare the luminous intensity gains (in percentage) obtained in comparison with a flat glass without texture, in the case where the plates are in an upright position for an annual exhibition in Cologne in Germany, in the case of direct light or in the case of diffuse light.
• a plaque was placed on either side of a vertical wall that could have a north-south (N / S) orientation to face west for one of the plates on one side of the wall, and facing the is for the other plate located on the other side.
• the wall could also have an east-west orientation (E / O) to face south for one of the plates located on one side of the wall, and facing north for the other plate located on the other side.
