[0002] With the continuous upgrading of car lighting technology, the design of light guide components, as an important part of car lights, also needs to adapt to the development trend of car lights to meet the demand for more uniform light emission. However, in the current design of conventional light guide components, such as Figure 1 As shown, the optical waveguide teeth 1' are all tilted in the same direction. The light in the optical waveguide element reaches the optical waveguide teeth 1' and is totally reflected before being emitted. The emission directions of the emitted light are also the same. This may cause the emitted light to be too concentrated, resulting in dark areas on the optical waveguide element, and the lighting uniformity and brightness of each area of ​​the optical waveguide element cannot be guaranteed.

[0038] like Figure 2As shown, an embodiment of the utility model provides a light guide element, including a light guide body 1, a reflection surface of the light guide body 1 includes a plurality of first light guide teeth 10 and a second light guide tooth 20, a light is emitted after total reflection by the first light guide tooth 10 to form a first light 2, and a light is emitted after total reflection by the second light guide tooth 20 to form a second light 3, and the light emission directions of at least part of the first light 2 and at least part of the second light 3 are not parallel. Specifically, the light guide body 1 can be a long strip structure, and a plurality of first light guide teeth 10 and second light guide teeth 20 are arranged on the reflection surface of the light guide body 1 along the length direction of the light guide body 1, the reflection surface of the first light guide tooth 10 and the reflection surface of the second light guide tooth 20 are respectively formed into different sawtooth structures, and the inclination angle of the reflection surface of the first light guide tooth 10 relative to the XY plane is different from the inclination angle of the reflection surface of the second light guide tooth 20 relative to the XY plane, so that the first light 2 and the second light 3 can be non-parallel. Specifically, when at least part of the first light 2 is emitted toward the left, at least part of the second light 3 can be emitted toward the right. According to actual use requirements, the specific emission directions of the first light 2 and the second light 3 can be controlled by changing the inclination angle of the reflection surface of the first light guide tooth 10 and the second light guide tooth 20 relative to the XY plane. On the light guide body 1, the inclination angles of the reflection surfaces of the multiple first light guide teeth 10 relative to the XY plane can be different, and the inclination angles of the reflection surfaces of the multiple second light guide teeth 20 relative to the XY plane can be different. After passing through the different reflection surfaces of the first light guide tooth 10 and the second light guide tooth 20, the light can be diffused and emitted in different directions, thereby reducing the dark areas that may appear in different areas of the light guide element, ensuring the lighting uniformity while improving the light efficiency of the light guide element.

[0039] In some embodiments, reference Figures 3 to 5 , the first light guide tooth 10 includes a first reflection surface 101 and a second reflection surface 102, the second light guide tooth 20 includes a third reflection surface 201 and a fourth reflection surface 202, the second reflection surface 102 is connected to the third reflection surface 201 through the first connecting surface 30, and the fourth reflection surface 202 is connected to the first reflection surface 101 through the second connecting surface 40, so that the first light guide tooth 10 and the second light guide tooth 20 are arranged in sequence in the length direction of the light guide body 1. Specifically, the first light guide tooth 10 and the second light guide tooth 20 arranged in intervals in the length direction of the light guide body 1 can make the light guide body 1 relatively narrow in the width direction, meeting the application requirements of narrow light guide elements in the vehicle lamp, such as the outline of the vehicle lamp and the lines of the vehicle body. Furthermore, the first connecting surface 30 and the second connecting surface 40 can also be reflection surfaces to increase the reflection effect of light in the light guide body, so that more light can be reflected and then emitted.

[0040] In some embodiments, reference Figure 3, the first optical tooth 10 is formed as a protruding structure protruding outward, and the second optical tooth 20 is formed as a groove structure concave inward. Specifically, the upper ends of the first reflection surface 101 and the second reflection surface 102 are connected to form a tooth-like structure, which protrudes in the positive direction of the Z direction; the lower ends of the third reflection surface 201 and the fourth reflection surface 202 are connected to form a tooth-like structure, which is concave in the negative direction of the Z direction. The first reflection surface 101 and the second reflection surface 102 have different inclination angles relative to the XY plane, and the third reflection surface 201 and the fourth reflection surface 202 have different inclination angles relative to the XY plane. At least one of the reflection surfaces of the first optical tooth 10 and the second optical tooth 20 has a different inclination angle relative to the XY plane from the other reflection surfaces, so that the reflection angle of the light is more diversified, which can make the lighting effect of the optical waveguide element more three-dimensional and full. When the first light guide tooth 10 and the second light guide tooth 20 are arranged in sequence, the lower end of the first reflection surface 101 is connected to one end of the first connection surface 30, the other end of the first connection surface 30 is connected to the upper end of the fourth reflection surface 202, the lower end of the second reflection surface 102 is connected to one end of the second connection surface 40, the other end of the second connection surface 40 is connected to the upper end of the third reflection surface 201, and the heights of the first connection surface 30 and the second connection surface 40 in the Z direction can be consistent, and the first connection surface 30 and the second connection surface 40 can be arranged parallel to the XY plane. The first light guide tooth 10 can be tilted to the right, and the second light guide tooth 20 can be tilted to the left, so that the first light 2 is emitted to the right and the second light 3 is emitted to the left. The first light 2 and the second light 3 have different emission directions, which can make the light more evenly distributed in the light guide body 1 and reduce the appearance of dark areas. The inclination angles of the first light guide teeth 10 and the second light guide teeth 20 can be adjusted according to actual use requirements to meet the lighting requirements of different vehicle models, providing more creativity and possibilities for vehicle lamp design.

[0041] In some embodiments, reference Figure 4, the first light guide tooth 10 and the second light guide tooth 20 are both formed into an inwardly concave groove structure, the inclination angle of the fourth reflection surface 202 relative to the XY plane is smaller than the inclination angle of the second reflection surface 102 relative to the XY plane, and preferably, the length of the first connecting surface 30 in the X direction is smaller than the length of the second connecting surface 40 in the X direction. Specifically, the heights of the first connecting surface 30 and the second connecting surface 40 in the Z direction may be consistent, and the first connecting surface 30 and the second connecting surface 40 may be arranged parallel to the X direction. The lower ends of the first reflection surface 101 and the second reflection surface 102 are connected to form a tooth-like structure, and the lower ends of the third reflection surface 201 and the second reflection surface 102 are connected to form a tooth-like structure. For example, the first light guide tooth 10 may be tilted to the left, and the second light guide tooth 20 may also be tilted to the left, but the inclination angle of the first light guide tooth 10 is smaller than the inclination angle of the second light guide tooth 20, at which time the first light 2 may be deflected to the right and the second light 3 may be deflected to the left. In addition, the first light guide tooth 10 may also be tilted to the right, and the second light guide tooth 20 may also be tilted to the right. The inclination angle of the fourth reflection surface 202 relative to the XY plane may be smaller than the inclination angle of the second reflection surface 102 relative to the XY plane, or may be larger than the inclination angle of the second reflection surface 102 relative to the XY plane, as long as the angle value of the inclination angle of the second reflection surface 102 relative to the XY plane and the inclination angle of the fourth reflection surface 202 relative to the XY plane have a difference, so as to ensure that the first light 2 and the second light 3 are diffused and emitted in different directions, so that the light can be more evenly distributed in the entire lighting area, reducing the dark area of ​​the lighting, and improving the lighting effect of the light guide element. Specifically, the angle value and inclination direction of the inclination angle of the first light guide tooth 10 and the second light guide tooth 20 relative to the XY plane can be determined according to actual usage requirements.

[0042] In some embodiments, reference Figure 5, the first reflection surface 101 and the second reflection surface 102, the third reflection surface 201 and the fourth reflection surface 202 are all formed as a convex structure protruding outward, the inclination angle of the fourth reflection surface 202 relative to the XY plane is greater than the inclination angle of the second reflection surface 102 relative to the XY plane, and preferably, the length of the first connecting surface 30 in the X direction is greater than the length of the second connecting surface 40 in the X direction. Specifically, the heights of the first connecting surface 30 and the second connecting surface 40 in the Z direction may be consistent, and the first connecting surface 30 and the second connecting surface 40 may be arranged parallel to the X direction. The upper ends of the first reflection surface 101 and the second reflection surface 102 are connected to form a tooth-like structure, and the upper ends of the third reflection surface 201 and the second reflection surface 202 are connected to form a tooth-like structure. For example, the first light guide tooth 10 may be tilted to the left, and the second light guide tooth 20 may also be tilted to the left, at which time the second light 2 may be biased to emit to the left, and the second light 3 may be biased to emit to the right. In addition, the first light guide tooth 10 may also be tilted to the right, and the second light guide tooth 20 may also be tilted to the right. The inclination angle of the fourth reflection surface 202 relative to the XY plane can be greater than the inclination angle of the second reflection surface 102 relative to the XY plane, or can be less than the inclination angle of the second reflection surface 102 relative to the XY plane, as long as the angle value of the inclination angle of the second reflection surface 102 relative to the XY plane and the inclination angle of the fourth reflection surface 202 relative to the XY plane have a difference, so as to ensure that the first light 2 and the second light 3 are diffused and emitted in different directions, so that the light can be more evenly distributed in the entire lighting area, reducing the lighting dark area, and improving the lighting effect of the light guide element. Specifically, the angle value and inclination direction of the inclination angle of the first light guide tooth 10 and the second light guide tooth 20 relative to the XY plane can be determined according to actual usage requirements.

[0043] In some embodiments, reference Figures 6 to 8 , the first light guide tooth 10 and the second light guide tooth 20 are arranged along the Y direction, two adjacent first light guide teeth 10 are connected by the first connecting surface 30, and two adjacent second light guide teeth 20 are connected by the second connecting surface 40. The first light guide tooth 10 includes a first reflection surface 101 and a second reflection surface 102, and the second light guide tooth 20 includes a third reflection surface 201 and a fourth reflection surface 202. Specifically, the first connecting surface 30 and the second connecting surface 40 are connected to each other, and the first connecting surface 30 and the second connecting surface 40 can be consistent in height in the Z direction, and the first connecting surface 30 and the second connecting surface 40 can be arranged parallel to the XY plane. The first light guide tooth 10 and the second light guide tooth 20 can be arranged side by side along the Y direction on the light guide body 1, so that the size of the light guide body 1 in the Y direction is relatively wide, which can meet the application requirements of the vehicle lamp for a light guide element with a relatively wide size. Further, the first connecting surface 30 and the second connecting surface 40 can also be reflection surfaces to increase the reflection effect of light in the light guide body 1, so that more light can be reflected and then emitted.

[0044] In some embodiments, reference Figure 6 , the first reflecting surface 101 and the second reflecting surface 102 are formed into a convex structure protruding outward, the third reflecting surface 201 and the fourth reflecting surface 202 are formed into a groove structure concave inward, and the ends of the first connecting surface 30 and the second connecting surface 40 are connected. Specifically, the upper ends of the first reflecting surface 101 and the second reflecting surface 102 are connected to form a tooth-like structure, and the lower ends of the third reflecting surface 201 and the fourth reflecting surface 202 are connected to form a tooth-like structure, which can make the lighting effect of the light guide element more three-dimensional and full. The first light guide tooth 10 can be arranged perpendicular to the XY plane, and the second light guide tooth 20 can also be arranged perpendicular to the XY plane, wherein the first reflecting surface 101 and the second reflecting surface 102, and / or the third reflecting surface 201 and the fourth reflecting surface 202 have different inclination directions relative to the XY plane. At this time, at least part of the first light 2 is emitted toward the left, and at least part of the second light 3 is emitted toward the right. In addition, the setting angles of the first light guide tooth 10 and the second light guide tooth 20 relative to the XY plane can be set according to actual use requirements. For example, the first light guide tooth 10 and the second light guide tooth 20 can be set at an angle to the left or right relative to the XY plane, so that at least part of the first light 2 and at least part of the second light 3 have different emission directions, which can make the light more evenly distributed in the entire lighting area, reduce the dark area of ​​the light guide element, and improve the lighting effect of the light guide element. The lengths of the first connecting surface 30 and the second connecting surface 40 in the X direction can be the same, so that the first light guide teeth 10 and the second light guide teeth 20 arranged in parallel correspond to each other in the X direction. The lengths of the first light guide teeth 10 and the second light guide teeth 20 in the Y direction can be the same or different. The first light guide teeth 10 and the second light guide teeth 20 with the same length in the Y direction can make the light distribution formed in the emission direction of the first light 2 and the light distribution formed in the emission direction of the second light 3 the same. The first light guide teeth 10 and the second light guide teeth 20 with different lengths in the Y direction can form light distributions of different sizes. Users can adjust the length difference of the first light guide teeth 10 and the second light guide teeth 20 in the Y direction according to actual use requirements.

[0045] In some embodiments, reference Figure 7, the first reflection surface 101 and the second reflection surface 102, the third reflection surface 201 and the fourth reflection surface 202 are all formed into an inwardly concave groove structure, the inclination angle of the second reflection surface 102 relative to the XY plane is smaller than the inclination angle of the fourth reflection surface 202 relative to the XY plane, and one side edge of the first connecting surface 30 and the second connecting surface 40 are aligned and connected. Specifically, the lower ends of the first reflection surface 101 and the second reflection surface 102 are connected to form a tooth-like structure, and the lower ends of the third reflection surface 201 and the fourth reflection surface 202 are connected to form a tooth-like structure. For example, the first light guide tooth 10 can be tilted to the left, and the second light guide tooth 20 can be tilted to the left. At this time, the exit direction of at least part of the first light 2 is tilted to the left, and the exit direction of at least part of the second light 3 is tilted to the right. In addition, the deflection angles of the first light guide tooth 10 and the second light guide tooth 20 can be set according to actual use requirements. For example, the first light guide tooth 10 and the second light guide tooth 20 can both be tilted to the right. The length of the first connecting surface 30 in the X direction is smaller than the length of the second connecting surface 40 in the X direction, and the heights of the first connecting surface 30 and the second connecting surface 40 in the Z direction may be consistent or inconsistent. The inclination angle of the second reflecting surface 102 relative to the XY plane may be smaller than the inclination angle of the fourth reflecting surface 202 relative to the XY plane, or may be greater than the inclination angle of the fourth reflecting surface 202 relative to the XY plane, that is, the inclination angle of the second reflecting surface 102 relative to the XY plane and the inclination angle of the fourth reflecting surface 202 relative to the XY plane have a difference in angle value, so as to ensure that at least part of the first light 2 and at least part of the second light 3 are diffused and emitted in different directions, so that the light can be more evenly distributed in the entire lighting area, reducing the lighting dark area, and improving the lighting effect of the light guide element. The lengths of the first light guide tooth 10 and the second light guide tooth 20 in the Y direction may be the same or different. The first light guide tooth 10 and the second light guide tooth 20 with the same length in the Y direction can make the light distribution formed in the emission direction of the first light 2 the same as the light distribution formed in the emission direction of the second light 3. The first light guide tooth 10 and the second light guide tooth 20 with different lengths in the Y direction can form light distributions of different sizes. The user can adjust the length difference of the first light guide tooth 10 and the second light guide tooth 20 in the Y direction according to actual usage requirements.

[0046] In some embodiments, reference Figure 8, the first reflection surface 101 and the second reflection surface 102, the third reflection surface 201 and the fourth reflection surface 202 are all formed as a convex structure protruding outward, the inclination angle of the third reflection surface 201 relative to the XY plane is smaller than the inclination angle of the first reflection surface 101 relative to the XY plane, the length of the first connecting surface 30 in the X direction is greater than the length of the second connecting surface 40 in the X direction, and one side of the first connecting surface 30 and the second connecting surface 40 are aligned and connected. Specifically, the upper ends of the first reflection surface 101 and the second reflection surface 102 are connected to form a tooth structure, and the upper ends of the third reflection surface 201 and the fourth reflection surface 202 are connected to form a tooth structure. The first light guide tooth 10 can be arranged perpendicular to the XY plane, and the second light guide tooth 20 can also be arranged perpendicular to the XY plane, wherein the first reflection surface 101 and the second reflection surface 102, and / or the third reflection surface 201 and the fourth reflection surface 202 have different inclination directions relative to the XY plane. At this time, at least part of the first light 2 is deflected to the left, and at least part of the second light 3 is deflected to the right. In addition, the setting angles of the first light guide tooth 10 and the second light guide tooth 20 relative to the XY plane can be set according to actual use requirements. For example, the setting angles of the first light guide tooth 10 and the second light guide tooth 20 can be biased to the left or right relative to the XY plane. The heights of the first connecting surface 30 and the second connecting surface 40 in the Z direction can be consistent or inconsistent. The inclination angle of the third reflection surface 201 relative to the XY plane can be less than the inclination angle of the first reflection surface 101 relative to the XY plane, or it can be greater than the inclination angle of the first reflection surface 101 relative to the XY plane, that is, the inclination angle of the first reflection surface 101 relative to the XY plane and the inclination angle of the third reflection surface 201 relative to the XY plane have a difference in angle value, so as to ensure that the first light 2 and the second light 3 are diffused and emitted in different directions, so that the light can be more evenly distributed in the entire lighting area, reducing the dark area of ​​the lighting, and improving the lighting effect of the light guide element. The lengths of the first light guide tooth 10 and the second light guide tooth 20 in the Y direction may be the same or different. The first light guide tooth 10 and the second light guide tooth 20 with the same length in the Y direction can make the light distribution formed in the emission direction of the first light 2 the same as the light distribution formed in the emission direction of the second light 3.
