Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular, to a thin-walled optical element with dynamic adjustment, a manufacturing method and a system. Background Art

[0002] In the prior art, thick-walled light guides are usually used in various lamps to conduct LED light from the light-entering surface to the light-emitting surface through total reflection. However, this light guide method prevents light from leaking on the side walls of the thick-walled light guide and can only form a simple luminous pattern on the light-emitting surface. This design is relatively simple in imaging effect and lacks detail expression and diversity of visual effects.

[0003] The existing technology for realizing dynamic lighting of vehicle lights often requires the use of complex electronic control, a large number of light sources, and a complex optical system, which requires high costs.

[0004] The existing Chinese patent with publication number CN112610932A discloses a multi-light-emitting area surface light source and a vehicle light module. The multi-light-emitting area surface light source includes a circuit board and an LED lamp, and the LED lamp is arranged on the circuit board; a reflector grille, and the reflector grille is arranged on the circuit board. The reflector grille includes a plurality of phase-separated areas, and an LED lamp is arranged at the center of each area. Each LED lamp is independently controlled, and the optical center distance L between two adjacent LED lamps and the height H of the reflector grille satisfy the formula: L / H=tan(δ / 2), where δ is the light output angle of the LED lamp after passing through the diffusion film; the diffusion film is arranged on the reflector grille and covers the LED lamp. The multi-light-emitting area surface light source provided in the present application can realize the conversion from point light source to surface light source with the least LED lamps, and the lighting and extinguishing of the LED lamp in each light-emitting area can be independently controlled, and the pixelated surface light source effect is realized very economically; a thin diffusion film is used, and no additional diffusant or internal light distribution mirror mixed with diffusant material is required, so that a better light uniformity effect can be achieved.

[0005] The disadvantages of the prior art are that the structure is complex, the light-emitting element cannot be dynamically adjusted, and the imaging effect is single, which needs to be improved. Summary of the invention

[0006] In view of the defects in the prior art, the purpose of this application is to provide a thin-walled optical element with dynamic adjustment and a manufacturing method thereof, aiming to achieve multi-angle dynamic lighting effects through arc patterns on thin-walled parts and laser-engraved leather patterns, thereby overcoming the shortcomings of the prior art.

[0007] According to the present application, a thin-walled optical element with dynamic adjustment includes: a thin-walled light source plate, a light source, a thin-walled member, and a rotating motor;

[0008] The rear wall of the thin-walled part is provided with a thin-walled part leather grain pattern, and the front wall of the thin-walled part is provided with a thin-walled part arc pattern;

[0009] The light source emits incident light into the thin-walled part, which is then totally reflected to form a thin-walled part leather grain pattern to transmit light. The thin-walled part leather grain pattern transmits light through the arc-shaped pattern of the thin-walled part to form an outgoing light from the thin-walled part. The rotating motor is connected to the thin-walled part and drives the thin-walled part to rotate.

[0010] Preferably, each group of the thin-walled parts' dermatoglyphic images is composed of at least two dermatoglyphic images of the same width, the intervals between two adjacent dermatoglyphic images in the same group are equal, and the curvature r and width of any arc-shaped pattern of the thin-walled parts in the same group are completely the same.

[0011] Preferably, the thin-walled member leather grain pattern of the rear wall of the thin-walled member is composed of a plurality of groups of vertical stripe patterns, and the thin-walled member arc pattern is composed of at least two arc columnar units. The corresponding relationship between the observation angle and the imaging is realized by the following formula:

[0012]

[0013] f is the effective focal length, which is the distance from the center of the arc’s curvature to the focal point of the parallel light rays;

[0014] r is the radius of curvature of the arc pattern of the thin-walled part;

[0015] n is the refractive index of the thin-walled part;

[0016]

[0017] D is the shortest horizontal straight line distance from the center of curvature of the arc pattern of the thin-walled part to the line connecting the two ends of the arc pattern;

[0018] W is the width of the arc pattern of the thin-walled part;

[0019]

[0020] W is the width of the arc pattern of a single thin-walled part;

[0021] A is the width of a single stripe of the striped dermatoglyphic image;

[0022] H is the thickness of the thin-walled part;

[0023] f is the effective focal length of a single arc cylindrical unit;

[0024] D is the shortest straight-line distance from the center of curvature of the arc pattern to the arc pattern;

[0025] Substituting formula (1) and formula (2) into formula (3), we can get the relationship between the parameters in the thin-walled part, as shown in formula (4):

[0026]

[0027]

[0028] When the incident angle of the parallel light is at an angle θ with the horizontal direction, the light perpendicular to the arc-shaped pattern section of the thin-walled part enters the thin-walled part at an incident angle of 0°, so the angle of the light will not change. After entering the thin-walled part, the light passes through the curvature center of the arc-shaped pattern of the thin-walled part to reach the light convergence position, and the remaining light will also converge near this position. The light can converge to the position A' of the leather pattern of the adjacent group. When the angle between the observation angle and the horizontal direction changes from 0° to θ, the converged light position changes from A to A'. Substituting formula (2) into formula (5), the change value of θ can be calculated;

[0029]

[0030] θ is the change in the angle between the incident light and the horizontal direction;

[0031] A is the change distance of the position center.

[0032] Preferably, the thin-walled member has a total reflection function, a light source incident surface is provided on the thin-walled member, and the light source is provided at the light source incident surface;

[0033] The incident light is refracted at the incident surface of the light source and enters the thin-walled part. The incident light is totally reflected inside the thin-walled part. The incident light leaks at the leather grain pattern of the thin-walled part, thereby lighting up the leather grain pattern of the thin-walled part.

[0034] Preferably, the thin-walled part leather grain pattern is engraved by laser engraving, and the leather grain pattern material of the thin-walled part is frosted material;

[0035] The arc-shaped pattern of the thin-walled part is formed by injection molding or machining.

[0036] Preferably, the light source is an LED light source that directly emits light into an optical system, and / or an optical system that guides light into an optical system.

[0037] Preferably, the thin-walled light source board shared by the light sources is a PE / PCB board.

[0038] The present application also provides a method for manufacturing a thin-walled optical element with dynamic adjustment, comprising the following steps:

[0039] Printing a thin-walled part leather grain pattern on the side wall of the thin-walled part;

[0040] Arranging a light source at the incident surface of the thin-walled member;

[0041] A thin-walled part cambered surface pattern is arranged on the opposite side of the thin-walled part leather grain pattern.

[0042] Preferably, when the thin-walled part is injection molded, a pattern matching the leather grain pattern of the thin-walled part is engraved on the mold of the side wall of the thin-walled part.

[0043] The present application also provides a thin-walled optical system for achieving dynamic effects, characterized in that it comprises at least two thin-walled optical elements with dynamic adjustment, and the rotating motors of the thin-walled optical elements with dynamic adjustment can rotate at different angles respectively.

[0044] Compared with the prior art, this application has the following beneficial effects:

[0045] 1. This application uses specially designed thin-walled parts to achieve interesting and variable dynamic lighting effects using only one part, thereby achieving the effect of extremely simplifying the system.

[0046] 2. This application adopts a simple structural design and specially designed arc patterns and leather patterns of thin-walled parts to solve the problem that a single thin-walled part can only achieve a single lighting effect, and achieves a lighting effect that changes with the observation angle, achieving the purpose of overall dynamic lighting with a minimalist optical system.

[0081] The present application is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present application. These all belong to the protection scope of the present application.

[0082] The thin-walled optical element with dynamic adjustment provided by the present application includes: a thin-walled light source plate 1, a light source 11, a thin-walled part 2 and a rotating motor 4; the rear wall of the thin-walled part 2 is provided with a thin-walled part leather grain pattern 22, and the front wall of the thin-walled part is provided with a thin-walled part arc pattern 23; the light source 11 emits incident light into the thin-walled part 2, which is then totally reflected to form the thin-walled part leather grain pattern 22 to transmit light, and the thin-walled part leather grain pattern 22 transmits light to pass through the thin-walled part arc pattern 23 to form the outgoing light of the thin-walled part, the rotating motor 4 is connected to the thin-walled light source plate 1 and the thin-walled part 2, and the thin-walled part 2 can rotate following the rotation of the rotating motor 4.

[0083] The following is a feasible embodiment of the present application. Figure 3 As shown, it is a schematic diagram of the structure of the thin-walled optical element with dynamic adjustment involved in the present application, which includes a thin-walled light source plate 1, a light source 11, a thin-walled part 2 and a rotating motor 4. The light source 11 is fixedly arranged on the thin-walled light source plate 1, and the material of the thin-walled part 2 can be transparent PMMA or transparent PC. Among them, the light emitted by the light source 11 is refracted into the thin-walled part 2 through the thin-walled part light source incident surface 21, and undergoes multiple total reflections in the thin-walled part 2. These light rays will undergo multiple total reflections in the thin-walled part 2, and finally, after completing total reflection on the thin-walled part total reflection surface 24, they are emitted into the air through the thin-walled part arc pattern 23. The optical path schematic diagram of this part of the light is shown in FIG. Figure 2 shown.

[0084] The front of the thin-walled member 2 is provided with regularly distributed thin-walled member arc patterns 23. The front view of the thin-walled member 2 is as follows Figure 4 The thin-walled component leather grain image 22 of the rear wall region corresponding to each group of thin-walled component arc patterns 23 consists of at least two leather grain images of the same width, the intervals between two adjacent leather grain images of the same group are equal, and the curvature r and width of any thin-walled component arc pattern 23 are exactly the same.

[0085] The arc r and width W of the arc-shaped pattern 23 on the front of the thin-walled member 2 and the thickness H of the thin-walled member 2 jointly determine the lighting effect seen by the human eye from different angles. Figure 5 As shown. The thin-walled part leather grain image 22 is composed of N groups of different striped leather grain images. Each group of images is composed of multiple striped leather grain images 22 with a width of W, and the width of a single stripe is equal to A. The stripes of multiple images are arranged in sequence, and finally form a complete thin-walled part leather grain image 22.

[0086] The thin-walled member leather grain pattern 22 on the back of the thin-walled member 2 is composed of a plurality of groups of vertical stripe patterns. Figure 6 shown.

[0087] The arc-shaped pattern 23 of the thin-walled member of a single arc columnar unit is a surface formed by longitudinally stretching an arc line of arc r, which has a convergence effect on horizontal light but no convergence effect on vertical light. The refraction effect of a single arc columnar unit on vertical light is as follows: Figure 7 shown.

[0088] The focusing state of a single arc columnar unit on horizontal light is as follows: Figure 8 shown.

[0089] like Figure 8 As shown, f is the effective focal length, that is, the distance from the center of the arc curvature to the focal point of the parallel light, r is the curvature radius of the arc pattern 23 of the thin-walled part, and n is the refractive index of the thin-walled part 2. According to the basic principles of geometric optics, the following formula (1) can be obtained:

[0090]

[0091] like Figure 8 As shown, D is the shortest horizontal straight line distance from the center of curvature of the thin-walled arc pattern 23 to the line connecting the two ends of the arc pattern, and W is the width of the thin-walled arc pattern 23:

[0092]

[0093] The width A of a single stripe of the stripe-like dermatoglyphic image depends on the position where the light converges, which is determined by the thickness H of the thin-walled member 2. The schematic diagram of the position of the converged light is shown in FIG. Fig. 9 shown.

[0094] like Fig. 9 As shown, W is the width of a single thin-walled arc pattern 23, A is the width of a single stripe of the striped leather grain image, H is the thickness of the thin-walled part 2, f is the effective focal length of a single arc cylindrical unit, and D is the shortest horizontal straight line distance from the center of curvature of the arc pattern to the arc pattern. The relationship between the parameters can be seen in the following formula (3):

[0095]

[0096] Substituting formula (1) and formula (2) into formula (3), the relationship between the parameters in the thin-walled part 2 can be obtained, as shown in formula (4):

[0097]

[0098] When the incident angle of parallel light is θ with the horizontal direction, the light perpendicular to the section of the vertical thin-walled curved pattern 23 enters the thin-walled part 2 because the incident angle is equal to 0°, so the angle of the light will not change. After entering the thin-walled part 2, the light passes through the curvature center of the thin-walled curved pattern 23 to reach the light convergence position, and the remaining light will also converge near this position. When the observation angle and the horizontal direction The angle changes from 0° to θ, the convergent light position changes from A to A', and the light convergence state is as follows Fig.10 shown.

[0099] To simplify the calculation, θ is the change in the angle between the incident light and the horizontal direction, and A is the change distance of the position center, such as Fig.11 shown.

[0100] From this, the value of θ can be calculated, see formula (5):

[0101]

[0102] Substituting formula (2) into formula (5), we can get the changing θ value, see formula (6):

[0103]

[0104] The thin-walled member 2 has a leather grain pattern 22 on the back of the thin-walled member 2, which is composed of N groups of different patterns, W = N * A. In this invention, N = 4 groups of patterns are used as an example. The first group of leather grain patterns 221, the second group of leather grain patterns 222, the third group of leather grain patterns 223, and the fourth group of leather grain patterns 224. The thin-walled member leather grain pattern 22 composed of the four groups of leather grain patterns is shown in FIG. Fig.12 shown.

[0105] The light from the human eye to the thin-walled member 2 can be considered as parallel light, and the parallel light can be focused on the corresponding dermatoglyphic pattern through the refraction and convergence of the thin-walled member arc pattern 23. According to the reversible principle of light, the light illuminating the dermatoglyphic pattern 22 of the thin-walled member can be refracted into parallel light through the thin-walled member arc pattern 23 and propagated to the human eye. Therefore, when viewed from different angles, the parallel light from the human eye can be converged to the positions of different thin-walled member dermatoglyphic patterns 22 through the thin-walled member arc pattern 23 on the front of the thin-walled member 2, so that different groups of dermatoglyphic patterns can be seen.

[0106] When the rotating motor 4 rotates to angle 1, the human eye can see the corresponding first group of dermatoglyphic patterns 221 when looking at the transparent thin-walled member 2. Fig.13 The first group of dermatoglyphic patterns 221 seen when rotating to angle 1 is as shown in FIG. Fig.14 The schematic diagram of simulated lighting at angle 1 is shown in Fig.15 shown.

[0107] When the rotating motor 4 rotates to angle 2, the human eye can see the corresponding second group of dermatoglyphic patterns 222 when looking at the transparent thin-walled member 2. Fig.16 The second group of dermatoglyphic patterns 222 seen when rotated to angle 2 is as shown in FIG. Fig.17 The schematic diagram of the simulated lighting at angle 2 is shown in Fig.18 shown.

[0108] When the rotating motor 4 rotates to angle 3, the human eye can see the corresponding third group of dermatoglyphic patterns 223 when looking at the transparent thin-walled member 2. Fig.19 The third group of dermatoglyphic patterns 223 seen when rotated to angle 3 is as shown in FIG. Fig. 20 The schematic diagram of simulated lighting at angle 3 is shown in Fig.21 shown.

[0109] When the rotating motor 4 rotates to angle 4, the human eye can see the corresponding fourth group of dermatoglyphic patterns 224 when looking at the transparent thin-walled member 2. Fig. 22 The fourth group of dermatoglyphic patterns 224 seen when rotating to angle 4 is as shown in FIG. Fig.23 The schematic diagram of the simulated lighting at angle 4 is shown in Fig.24 shown.

[0110] When the rotation angle of the rotating motor 4 continues to change to angle 5, when the human eye looks at the transparent thin-walled member 2, the corresponding first group of dermatoglyphic patterns 221 can be seen again. Fig.25 The schematic diagram of simulated lighting at angle 5 is shown in Fig.26 shown.

[0111] Therefore, when the rotating motor 4 continues to rotate, driving the angle of the transparent thin-walled member 2 to continuously change, the corresponding dermatoglyphic pattern visible to the human eye changes sequentially. The dermatoglyphic pattern can be made into a continuously changing animated image to achieve a richer and more varied dynamic lighting effect.

[0112] For example, if multiple star patterns of different sizes and positions are made, when the viewing angle continues to change, the stars can be seen flickering. Fig. 27 As shown, the schematic diagram of the simulated lighting of the star leather pattern is as follows Fig.28 shown.

[0113] There are many options for the light-input optical system for lighting the thin-walled member 2. It can be an optical system for direct light input from an LED light source as mentioned in the previous case, or an optical system for light-input from a light guide, such as Fig.29 No matter what optical system is selected for the light input system, when it is lit in combination with the thin-walled part 2, the dynamic lighting effect mentioned in this case can be achieved.

[0114] The engraving method of the leather grain pattern 22 of the thin-walled part in this application is recommended to be laser engraving. The material of the leather grain pattern 22 of the thin-walled part is preferably frosted material. The molding method of the arc pattern 23 of the thin-walled part can be injection molding or processing molding. The material of the thin-walled part 2 can be selected from organic transparent glass or carbonate-based high molecular polymer.

[0115] The present application also provides a method for manufacturing a thin-walled optical element with dynamic adjustment, comprising the steps of:

[0116] S1: Printing a thin-walled part leather grain pattern 22 on the side wall of the thin-walled part 2;

[0117] S2: Arrange a light source 11 at the incident surface of the thin-walled member 2;

[0118] S3: a thin-walled part arc surface pattern 23 is provided on the opposite side of the thin-walled part leather grain pattern 22 .

[0119] Step S1 also includes sub-step S1.1: when injection molding the thin-walled part 2, engraving a pattern matching the leather grain pattern 22 of the thin-walled part on the mold of the side wall of the thin-walled part 2.

[0120] The present application can also be used in conjunction with multiple thin-walled optical elements with dynamic adjustment to form a thin-walled optical system that achieves dynamic effects. When multiple rotating motors rotate separately, there can be a variety of different lighting effects. Fig.30 , 31 shown.
