Description

Technical Field

[0001] The utility model belongs to the technical field of stage lighting fixtures, in particular to a new type of mirror row. Background Art

[0002] In the stage lighting industry, in order to create dazzling and colorful lighting effects, the method of adding rows of mirrors to the lamps is often used to obtain a variety of light spot effects. The number of light emitting planes of the row of mirrors determines the number of light spots produced. For example, the commonly used eight rows of mirrors can refract the light beam into eight light beams. At present, single-row mirrors are a more common choice. When the light beam passes through a single-row mirror, a row of light spots arranged in a straight line will be formed.

[0003] When the number of light-emitting planes of a single-row mirror increases, if the traditional single-row design is continued, obvious light spot tailing will occur. This is because as the number of light-emitting planes increases, due to the limitations of the reflection angle and path, part of the light beam cannot be accurately focused when it is reflected by the single-row mirror, thus forming light spot tailing at both ends. In addition, the light spot formed by the single-row mirror is distributed in a straight line. Although it is simple and clear, it appears to be relatively simple when pursuing colorful stage effects, and it is difficult to meet the complex and changing needs of stage performances. Summary of the invention

[0004] The new row of mirrors for stage lighting provided by the utility model significantly solves the problem of light spot tailing that may occur when the light output plane increases, thereby improving the clarity and beauty of the stage lighting effect. The design feature of this new row of mirrors is its double-row design, which enables the light spot to be presented as a more uniform and compact double-row straight line distribution. This double-row design not only optimizes the distribution form of the light spot, but also significantly shortens the X-direction distance of the light spot distribution compared to a single-row mirror. The X-direction distance of the light spot distribution has a greater impact on the light spot. For example, the X-direction distribution distance of the light spot of the traditional single-row eight-row mirror is significantly longer than the X-direction distribution distance of the light spot of the eight-row mirror of the utility model. While retaining the number of light spots of the traditional eight-row mirror, the utility model solves the problem of severe tailing of the light spot at both ends when the single-row mirror is distributed in a single row by shortening the X-direction distribution distance of the light spot.

[0005] In order to solve the above problems, the utility model adopts the following solutions:

[0010] As a further improvement of the utility model, five side light emitting planes are distributed on the side light emitting surface 4, which are the first side light emitting plane 5, the second side light emitting plane 6, the third side light emitting plane 8, the second side light emitting plane 6, and the first side light emitting plane 5 in sequence; the angle a between the first side light emitting plane 5 and the light incident surface 2 is in the range of 12° to 27°, and the angle b between the second side light emitting plane 6 and the light incident surface 2 is in the range of 4° to 9°; the third side light emitting plane 8 is parallel to the light incident surface 2; wherein the value range of a is 12° to 27°, and the value range of b is 4° to 9°.

[0011] As a further improvement of the utility model, six side light emitting planes are distributed on the side light emitting surface 4, which are the first side light emitting plane 5, the second side light emitting plane 6, the third side light emitting plane 8, the third side light emitting plane 8, the second side light emitting plane 6, and the first side light emitting plane 5 in sequence; the angle a between the first side light emitting plane 5 and the light incident surface 2 is in the range of 15° to 30°, the angle b between the second side light emitting plane 6 and the light incident surface 2 is in the range of 12° to 27°, and the angle c between the third side light emitting plane 8 and the light incident surface 2 is in the range of 4° to 9°; wherein the value range of a is 15° to 30°, the value range of b is 12° to 27°, and the value range of c is 4° to 9°.

DETAILED DESCRIPTION Example

[0052] The utility model is described in detail below in conjunction with the accompanying drawings.

[0053] Combined with Figure 1 The mirror row includes a light incident surface 2 and a light emitting surface 1. The light incident surface 2 is a plane. The light emitting surface 1 includes two light emitting surfaces 4 distributed on both sides of the central dividing surface 3 and symmetrical to each other. There are three side light emitting planes connected in sequence from beginning to end on the side light emitting surface 4, namely, the first side light emitting plane 5, the second side light emitting plane 6, and the first side light emitting plane 5. The three side light emitting planes are symmetrically distributed along the orthogonal plane 7 of the central dividing surface 3, that is, the first side light emitting planes 5 are symmetrical to each other. The beneficial effect of this embodiment is that, as shown in the attached figure, Figure 7a As shown in the figure, the traditional single-row mirror will form a row of light spots distributed in a straight line. When the number of light-emitting planes increases, the light spots at both ends will have obvious tailing phenomenon. The tailing phenomenon means that the light spots at the beginning and end are relatively blurred, as shown in the dotted line part. Among the six light spots formed, the first and sixth light spots will be relatively blurred. Figure 7b As shown, the utility model solves the problem of light spot tailing at the head and tail ends, and forms two rows of light spots distributed in an array, with six light spots divided into two rows, each of which is very clear. That is, while retaining the number of light spots emitted by the traditional six-row mirror, the problem of light spot tailing at the head and tail ends is solved by optimizing the light spot arrangement and shortening the distribution distance of the light spots in the X-direction.

[0054] As a new implementation method, combined with the Figure 1, the intersection line of the two side light emitting surfaces 4 is the dividing line 31 of the central dividing surface, and the dividing line 31 is a plurality of fold lines connected end to end, and each side light emitting plane intersects with the central dividing surface 3 respectively. The beneficial effect of this embodiment is that when the fold line is used as the dividing line 31, it is conducive to the uniform arrangement of the light spots and maintains a relatively uniform spacing between the light spots. The design that each side light emitting plane intersects with the central dividing surface 3 is to ensure that the light beam passes through each light emitting plane and forms two rows of light spots arranged in an array.

[0055] As a new implementation method, combined with the Figure 1 and attached Figure 5 , the angle a between the first side light emitting plane 5 and the light incident surface 2 is in the range of 4° to 30°, and the second side light emitting plane 6 is parallel to the light incident surface 2, wherein the value of a is in the range of 4° to 30°. The beneficial effect of this embodiment is that the light spots emitted by the mirror array can present a better matrix distribution state. The angle between the light emitting plane on each side and the light incident surface 2 is related to the spacing between the light spots in the X direction. The larger the angle, the larger the spacing between the light spots. The spacing of the light spots in the X direction should not be too large, otherwise it will cause the phenomenon of light spot tailing.

[0056] In a more preferred embodiment, when the included angles between the two first-side light-emitting planes 5 and the light-incident plane 2 are equal, the lateral directions of the light spots formed by the array of mirrors are equal, that is, d1=d2.

[0057] As a new implementation method, combined with the Figure 1 and attached Figure 4 , the surface area of ​​the light emitting plane on each side of the row of mirrors is equal. The beneficial effect of this embodiment is that this unique design allows the light emitting plane on each side of the row of mirrors to emit light evenly when working, avoiding the problem of uneven brightness caused by surface area differences. When light passes through the row of mirrors, since the surface area of ​​the light emitting plane on each side is equal, the light can be scattered in a more balanced way, and the formed light spot has a higher brightness consistency.

[0058] As a new implementation method, combined with the Figure 1 and attached Figure 5, the angle δ between the intersection line 41 of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 30°; that is, the angle between the intersection line 41 of the first side light emitting plane 5 and the second side light emitting plane 6 and the horizontal plane is equal. The beneficial effect of this embodiment is that the longitudinal spacing h between the two rows of light spots formed by the unique design of equal angle δ is equal, that is, h1=h2. The angle δ is related to the longitudinal spacing h of the light spots. When the angle δ increases, the longitudinal distance h of the light spots will also increase. When the angle δ increases to a certain extent, the longitudinal distance h between the light spots is too large, and the phenomenon of light spot tailing will occur; when the angle δ decreases, the longitudinal distance of the light spots will also decrease. When the angle δ gradually approaches zero, the light spots formed overlap because the longitudinal distance h is too small. When ∠δ=0, the light spots projected by the row of mirrors are single-row light spots.

[0059] As a special implementation method, as shown in the attached Figure 5 ,6,7b, the angle a between the first side light emitting plane 5 and the light incident surface 2 is in the range of 4° to 30°, and the second side light emitting plane 6 is parallel to the light incident surface 2. The angle δ between the intersection line 41 of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 30°. At the same time, the angles between the two first side light emitting planes 5 and the light incident surface 2 are equal, ∠a=∠δ, and when d1=d2=h1=h2, the figure surrounded by the centers of the four light spots in the dotted frame A is a square.

[0060] As a new implementation method, combined with the Figure 1 , the light incident surface 2 is a circular plane parallel to the horizontal plane. The beneficial effect of this embodiment is that the circular light incident surface can effectively collect light from different directions and guide it to the same focus, thereby improving the light focusing ability and imaging quality of the optical system.

[0061] As a new implementation, the material of the row of mirrors in the utility model is optical glass, and its refractive index is 1.4 to 1.75. The beneficial effect of this implementation is that the optical glass has the characteristics of high light transmittance, high temperature resistance and chemical resistance, which has significant advantages over traditional materials and can better adapt to complex working environment conditions. Example

[0062] Combined with Figure 8The mirror array includes a light incident surface 2 and a light emitting surface 1. The light incident surface 2 is a plane, and the light emitting surface 1 includes two side light emitting surfaces 4 distributed on both sides of the central dividing surface 3 and symmetrical to each other. There are four side light emitting planes connected end to end on the side light emitting surface 4, namely, a first side light emitting plane 5, a second side light emitting plane 6, a second side light emitting plane 6, and a first side light emitting plane 5. The four side light emitting planes are symmetrically distributed along the orthogonal plane 7 of the central dividing surface 3, that is, the first side light emitting planes 5 are symmetrical to each other, and the second side light emitting planes 6 are symmetrical to each other. The beneficial effect of this embodiment is that, as shown in the attached figure, Fig.14a As shown in the figure, the traditional single-row mirror will form a row of light spots distributed in a straight line, and when the number of light-emitting surfaces increases, the light spots at both ends will have obvious tailing phenomenon. The tailing phenomenon means that the light spots at the beginning and end are relatively blurred, as shown in the dotted line part. Among the eight light spots formed, the first and eighth light spots will be relatively blurred. As shown in the attached figure, Fig.14b As shown, the utility model solves the problem of light spot tailing in the traditional single-row mirror, and forms two rows of light spots distributed in an array, with eight light spots divided into two rows, each of which is very clear. That is, while retaining the number of light spots emitted by the traditional eight-row mirror, the light spot arrangement is optimized, the distribution distance of the light spot in the X direction is shortened, and the problem of light spot tailing at both ends is solved.

[0063] As a new implementation method, combined with the Figure 8 , the intersection line of the two side light-emitting surfaces 4 is the dividing line 31 of the central dividing surface, and the dividing line 31 is a plurality of broken lines connected end to end, and each side light-emitting plane intersects with the central dividing surface 3 respectively. The beneficial effect of this embodiment is that when the broken line is used as the dividing line 31, it is conducive to the uniform arrangement of the light spots and maintains a relatively uniform spacing between the light spots. In the design of traditional single-row mirrors in stage lighting, a light spot effect of a single straight line arrangement is formed. The design of each side light-emitting plane of the utility model intersecting with the central dividing surface 3 is to ensure that the light beam passes through each light-emitting plane and forms two rows of light spots arranged in an array.

[0064] As a new implementation method, combined with the Figure 8 and attached Fig.12 , the angle a between the first side light emitting plane 5 and the light incident surface 2 is in the range of 12° to 27°, and the angle b between the second side light emitting plane 6 and the light incident surface 2 is in the range of 4° to 9°. The beneficial effect of this embodiment is that the output light spots of the mirror array can present a better matrix distribution state. The angle between the light emitting plane on each side and the light incident surface 2 is related to the spacing between the light spots in the X direction. The larger the angle, the larger the lateral spacing between the light spots. The lateral spacing of the light spots should not be too large, otherwise it will cause the phenomenon of light spot tailing.

[0065] In a more preferred embodiment, when ∠a=3∠b, the lateral spacing d between the light spots formed by the mirror array is equal, that is, d1=d2.

[0066] As a new implementation method, combined with the Figure 8 and attached Fig.11 The utility model discloses a new type of mirror row, the surface area of ​​the light emitting plane on each side of the mirror row is equal. The beneficial effect of this embodiment is that this unique design scheme enables the light emitting plane on each side of the mirror row to emit light evenly when it is working, avoiding the problem of uneven brightness caused by surface area differences. When light passes through the mirror row, since the surface area of ​​the light emitting plane on each side is equal, the light can be scattered in a more balanced way, and the formed light spot has higher brightness consistency.

[0067] As a new implementation method, combined with the Figure 8 and attached Fig.13 , the angle δ between the intersection line of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 9°; that is, the angle between the intersection line 41 of the first side light emitting plane 5 and the second side light emitting plane 6 and the horizontal plane and the angle between the intersection line 42 of the two second side light emitting planes 6 and the horizontal plane are equal. The beneficial effect of this embodiment is that the design of equal angle δ makes the longitudinal spacing h between the two rows of light spots formed equal, that is, h1=h2. The angle δ is related to the longitudinal spacing h of the light spots. When the angle δ increases, the longitudinal distance h of the light spots will also increase. When the angle δ increases to a certain extent, the longitudinal distance h between the light spots is too large, and the phenomenon of light spot tailing will occur; when the angle δ decreases, the longitudinal distance of the light spots will also decrease. When the angle δ gradually approaches zero, the light spots formed overlap because the longitudinal distance h is too small. When ∠δ=0, the light spots projected by the row of mirrors are single-row light spots.

[0068] As a special implementation method, as shown in the attached Fig.12 , 13, 14b, the angle a between the first side light emitting plane 5 and the light incident surface 2 ranges from 12° to 27°, and the angle b between the second side light emitting plane 6 and the light incident surface 2 ranges from 4° to 9°. The angle δ between the intersection lines (41, 42) of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 9°. At the same time, when a=3b=3δ, d1=d2=h1=h2, at this time, the figure surrounded by the centers of the four light spots in the dotted frame B is a square.

[0069] As a new implementation method, combined with the Figure 8 , the light incident surface 2 is a circular plane parallel to the horizontal plane. The beneficial effect of this embodiment is that the circular light incident surface can effectively collect light from different directions and guide it to the same focus, thereby improving the focusing ability and imaging quality of the optical system.

[0070] As a new implementation method, the refractive index of the material of the row mirror itself has a great influence on the refraction angle and the light splitting effect. The material of the row mirror in the utility model is optical glass, and its refractive index is 1.4 to 1.75. The beneficial effect of this implementation method is that optical glass has the characteristics of high light transmittance, high temperature resistance and chemical resistance, which has significant advantages over traditional materials and can better adapt to complex working environment conditions. Example

[0071] Combined with Fig.15 The mirror array includes a light incident surface 2 and a light emitting surface 1. The light incident surface 2 is a plane, and the light emitting surface 1 includes two side light emitting surfaces 4 distributed on both sides of the central dividing surface 3 and symmetrical to each other. There are five side light emitting planes connected in sequence from beginning to end on the side light emitting surface 4, namely, the first side light emitting plane 5, the second side light emitting plane 6, the third side light emitting plane 8, the second side light emitting plane 6, and the first side light emitting plane 5. The five side light emitting planes are symmetrically distributed along the orthogonal plane 7 of the central dividing surface 3, that is, the first side light emitting planes 5 are symmetrical to each other, and the second side light emitting planes 6 are symmetrical to each other. The beneficial effect of this embodiment is that, if Fig.21a As shown in the figure, the traditional single-row mirror will form a row of light spots distributed in a straight line. When the number of light-emitting surfaces increases, the light spots at both ends will have obvious tailing phenomenon. The tailing phenomenon means that the light spots at the beginning and end are relatively blurred, as shown in the dotted line part. Among the ten light spots formed, the first and tenth light spots will be relatively blurred. Figure 21b As shown, the utility model solves the problem of light spot tailing at both ends, and forms two rows of light spots distributed in an array, with ten light spots divided into two rows, each of which is very clear. While retaining the number of light spots emitted by the traditional ten-row mirror, the arrangement of the light spots is optimized, the X-direction distribution distance of the light spots is shortened, and the problem of light spot tailing at both ends is solved.

[0072] As a new implementation method, combined with the Fig.15 , the intersection line of the two side light-emitting surfaces 4 is the dividing line 31 of the central dividing surface 3, the dividing line 31 is a plurality of continuous broken lines, and each side light-emitting plane intersects with the central dividing surface 3 respectively. The beneficial effect of this embodiment is that when the broken line is used as the dividing line 31, it is conducive to the uniform arrangement of the light spots and maintains a relatively uniform spacing between the light spots. In the design of traditional single-row mirrors for stage lighting, a light spot effect of a single straight line arrangement is formed. The design of each side light-emitting plane of the utility model intersecting with the central dividing surface 3 is to ensure that the light beam passes through each light-emitting plane and forms two rows of light spots arranged in an array.

[0073] As a new implementation method, combined with the Fig.15 and attached Fig.19, the angle a between the first side light emitting plane 5 and the light incident surface 2 is in the range of 12° to 27°, the angle b between the second side light emitting plane 6 and the light incident surface 2 is in the range of 4° to 9°, and the third side light emitting plane 8 is parallel to the light incident surface 2, wherein a is in the range of 12° to 27°, and b is in the range of 4° to 9°. The beneficial effect of this embodiment is that the emergent light spot of the mirror array can present a better matrix distribution state. The angle between the light emitting plane on each side and the light incident surface 2 is related to the spacing of the light spots in the X direction. The larger the angle, the larger the spacing between the light spots. The spacing of the light spots in the X direction should not be too large, otherwise it will cause the phenomenon of light spot tailing.

[0074] In a more preferred embodiment, when ∠a=3∠b, the lateral distribution distances between the light spots formed by the row of mirrors are equal, that is, d1=d2.

[0075] As a new implementation method, combined with the Fig.15 and attached Fig.18 , the surface area of ​​the light emitting plane on each side of the row of mirrors is equal. The beneficial effect of this embodiment is that this unique design allows the light emitting plane on each side of the row of mirrors to emit light evenly when working, avoiding the problem of uneven brightness caused by surface area differences. When light passes through the row of mirrors, since the surface area of ​​the light emitting plane on each side is equal, the light can be scattered in a more balanced way, and the formed light spot has a higher brightness consistency.

[0076] As a new implementation method, combined with the Fig.15 and attached Fig. 20 , the angle δ between the intersection line of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 9°. That is, the angle between the intersection line 41 of the first side light emitting plane 5 and the second side light emitting plane 6 and the horizontal plane is equal to the angle between the intersection line 43 of the second side light emitting plane 6 and the third side light emitting plane 8 and the horizontal plane. The beneficial effect of this embodiment is that the design of equal angle δ makes the longitudinal spacing h between the two rows of light spots formed equal, that is, h1=h2. The angle δ is related to the longitudinal spacing h of the light spots. When the angle δ increases, the longitudinal distance h of the light spots will also increase. When the angle δ increases to a certain extent, the longitudinal distance h between the light spots is too large, and the phenomenon of light spot tailing will occur; when the angle δ decreases, the longitudinal distance of the light spots will also decrease. When the angle δ gradually approaches zero, the light spots formed overlap because the longitudinal distance h is too small. When ∠δ=0, the light spots projected by the row of mirrors are single-row light spots.

[0077] As a special implementation method, as shown in the attached Fig.19, 20, 21b, the angle a between the first side light emitting plane 5 and the light incident surface 2 ranges from 12° to 27°, the angle b between the second side light emitting plane 6 and the light incident surface 2 ranges from 4° to 9°, and the third side light emitting plane 8 is parallel to the light incident surface 2, wherein the value range of a is 12° to 27°, and the value range of b is 4° to 9°. The angle δ between the intersection lines (41, 43) of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 9°. At the same time, when a=3b=3δ, d1=d2=h1=h2, and the figure surrounded by the centers of the four light spots in the dotted frame C is a square.

[0078] As a new implementation method, combined with the Fig.15 The light incident surface 2 is a circular plane parallel to the horizontal plane.

[0079] As a new implementation, the material of the row of mirrors in the utility model is optical glass, and its refractive index is 1.4 to 1.75. The beneficial effect of this implementation is that the optical glass has the characteristics of high light transmittance, high temperature resistance and chemical resistance, which has significant advantages over traditional materials and can better adapt to complex working environment conditions. Example

[0080] Combined with Fig. 22 The mirror row includes a light incident surface 2 and a light emitting surface 1. The light incident surface 2 is a plane, and the light emitting surface 1 includes two side light emitting surfaces 4 distributed on both sides of the central dividing surface 3 and symmetrical to each other. There are six side light emitting planes connected in sequence from beginning to end on the side light emitting surface 4, namely, a first side light emitting plane 5, a second side light emitting plane 6, a third side light emitting plane 8, a third side light emitting plane 8, a second side light emitting plane 6, and a first side light emitting plane 5. The six side light emitting planes are symmetrically distributed along the orthogonal plane 7 of the central dividing surface 3, that is, the first side light emitting planes 5 are symmetrical to each other, the second side light emitting planes 6 are symmetrical to each other, and the third side light emitting planes 8 are symmetrical to each other. The beneficial effect of this embodiment is that, as shown in the attached figure, Fig.28a As shown in the figure, the traditional single-row mirror will form a row of light spots distributed in a straight line. When the number of light-emitting surfaces increases, the light spots at both ends will have obvious tailing phenomenon. The tailing phenomenon means that the light spots at the beginning and end are relatively blurred, as shown in the dotted line part. Among the twelve light spots formed, the first and twelfth light spots will be relatively blurred. Fig.28bAs shown, the utility model solves the problem of light spot tailing at the head and tail ends, and forms two rows of light spots distributed in an array, with twelve light spots divided into two rows, each of which is very clear. While retaining the number of light spots emitted by the traditional twelve-row mirror, the problem of light spot tailing at the head and tail ends is solved by optimizing the light spot arrangement and shortening the X-direction distribution distance of the light spot.

[0081] As a new implementation method, combined with the Fig. 22 , the intersection line of the two side light emitting surfaces 4 is the dividing line 31 of the central dividing surface 3, the dividing line 31 is a plurality of continuous broken lines, and each side light emitting plane intersects with the central dividing surface 3 respectively. The beneficial effect of this embodiment is that when the broken line is used as the dividing line 31, it is conducive to the uniform arrangement of the light spots and maintains a relatively uniform spacing between the light spots. Fig.28a As shown in the figure, the traditional single-row mirror in stage lighting design forms a single straight line arrangement of light spots. Fig.28b As shown, the design of the utility model that each side light emitting plane intersects with the central dividing plane 3 is to ensure that the light beam passes through each light emitting plane and forms two rows of light spots arranged in an array.

[0082] As a new implementation method, combined with the Fig. 22 and attached Fig. 27 , the angle a between the first side light emitting plane 5 and the light incident surface 2 is in the range of 15° to 30°, the angle b between the second side light emitting plane 6 and the light incident surface 2 is in the range of 12° to 27°, and the angle c between the third side light emitting plane 8 and the light incident surface 2 is in the range of 4° to 9°, wherein the value range of a is 15° to 30°, the value range of b is 12° to 27°, and the value range of c is 4° to 9°. The beneficial effect of this embodiment is that the output light spot of the mirror array can present a better matrix distribution state. The angle between the light emitting plane on each side and the light incident surface 2 is related to the spacing of the light spots in the X direction. The larger the angle, the larger the spacing between the light spots. The spacing of the light spots in the X direction should not be too large, otherwise it will cause the phenomenon of light spot tailing.

[0083] In a more preferred embodiment, ∠c:∠b:∠a=1:3:5, and the lateral distribution distances between the light spots formed by the row of mirrors are equal, that is, d1=d2.

[0084] As a new implementation method, combined with the Fig. 22 and attached Fig.25 , the surface area of ​​the light emitting plane on each side of the row of mirrors is equal. The beneficial effect of this embodiment is that this unique design allows the light emitting plane on each side of the row of mirrors to emit light evenly when working, avoiding the problem of uneven brightness caused by surface area differences. When light passes through the row of mirrors, since the surface area of ​​the light emitting plane on each side is equal, the light can be scattered in a more balanced way, and the formed light spot has a higher brightness consistency.

[0085] As a new implementation method, combined with the Fig. 22 and attached Fig.25 , the angle δ between the intersection line of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 9°. That is, the angle between the intersection line 41 of the first side light emitting plane 5 and the second side light emitting plane 6 and the horizontal plane, the angle between the intersection line 43 of the second side light emitting plane 6 and the third side light emitting plane 8 and the horizontal plane, and the angle between the intersection line 44 of the two third side light emitting planes 8 and the horizontal plane are equal. The beneficial effect of this embodiment is that the design of equal angle δ makes the longitudinal spacing h between the two rows of light spots formed equal, that is, h1=h2. The angle δ is related to the longitudinal spacing h of the light spots. When the angle δ increases, the longitudinal distance h of the light spots will also increase. When the angle δ increases to a certain extent, the longitudinal distance h between the light spots is too large, and the phenomenon of light spot tailing will occur; when the angle δ decreases, the longitudinal distance of the light spots will also decrease. When the angle δ gradually approaches zero, the light spots formed overlap because the longitudinal distance h is too small. When ∠δ=0, the light spots projected by the row of mirrors are single-row light spots.

[0086] As a special implementation method, as shown in the attached Fig.26 , 27, 28b, the angle a between the first side light emitting plane 5 and the light incident surface 2 ranges from 15° to 30°, the angle b between the second side light emitting plane 6 and the light incident surface 2 ranges from 12° to 27°, and the angle c between the third side light emitting plane 8 and the light incident surface 2 ranges from 4° to 9°, wherein the value range of a is 15° to 30°, the value range of b is 12° to 27°, and the value range of c is 4° to 9°. The angle δ between the intersection lines (41, 43, 44) of every two adjacent side light emitting planes on the side light emitting surface 4 and the horizontal plane is equal, and the range of δ is 4° to 9°. At the same time, when ∠δ:∠c:∠b:∠a=1:1:3:5, d1=d2=h1=h2, and the figure surrounded by the centers of the four light spots in the dotted frame D is a square.

[0087] As a new implementation method, combined with the Fig. 22 The light incident surface 2 is a circular surface parallel to the horizontal plane. The beneficial effect of this embodiment is that the circular light incident surface can effectively collect light from different directions and guide it to the same focus, thereby improving the focusing ability and imaging quality of the optical system.

[0088] As a new implementation, the material of the row of mirrors in the utility model is optical glass, and its refractive index is 1.4 to 1.75. The beneficial effect of this implementation is that the optical glass has the characteristics of high light transmittance, high temperature resistance and chemical resistance, which has significant advantages over traditional materials and can better adapt to complex working environment conditions.
