[0007] According to one embodiment of the present invention, the outline of the first diffusion pattern on the vertical plane is consistent with the outline of the incident light unit, and the guide line of the first diffusion pattern in the horizontal plane is a curve, and the curve is convex to the negative direction of light emission, so as to diffuse the light in the horizontal direction.

[0021] The following describes in detail, with reference to the accompanying drawings, a miniature optical system suitable for signal light functions, and a vehicle light and vehicle including the same.

[0022] like Figures 1-6 As shown, a miniature optical system suitable for signal light functions according to an embodiment of the present invention includes: a light-incident section and a light-exiting section; the light-incident section is located in the light-exiting direction of the light source, and is composed of at least one light-incident unit 1, which has a light-converging function in at least one direction; the light-exiting section is located in the light-exiting direction of the light-incident section, and is composed of at least one light-exiting unit 2, the number of light-exiting units 2 being the same as the number of light-incident units 1, and when there are multiple light-incident units 1 and multiple light-exiting units 2, the multiple light-exiting units 2 correspond one-to-one with the multiple light-incident units 1; multiple first diffusion patterns are formed on the light-incident unit 1, and the multiple first diffusion patterns are arranged along the contour line trend in at least one direction, for diffusing the received light in at least one direction. That is, the first diffusion patterns can diffuse the light angle in a single direction or diffuse the light angle in multiple directions. When the first diffusion pattern diffuses light horizontally, multiple first diffusion patterns are arranged along the horizontal contour line of the light-incident unit 1; when the first diffusion pattern diffuses light vertically, multiple first diffusion patterns are arranged along the vertical contour line of the light-incident unit 1. The first diffusion pattern can have both horizontal and vertical diffusion functions; that is, it can be arranged both horizontally and vertically.

[0023] In this embodiment, the light source can be understood as the light distribution adjusted by the primary optical unit. The incident light unit 1 can converge the received light at least in the vertical direction, either into a small area or at a focal point. After convergence by the incident light unit 1, the angle at which the light reaches the emitting light unit 2 is reduced, allowing the emitting light unit 2 to receive a large amount of light at least in the vertical direction, improving light utilization and reducing the size of the emitting light unit 2 in the vertical direction. Simultaneously, since the light source is divided into multiple regions by multiple incident light units 1 and then refracted by multiple emitting light units 2, the light emission path is distributed in various directions, improving the uniformity of illumination.

[0024] It is understood that in this embodiment, the first diffusion pattern in the vertical direction is only used for fine adjustment of the light angle to improve the uniformity of illumination, and has little impact on the diffusion of the light angle. After being converged by the light-incident unit 1, the light diffused by the first diffusion pattern still reaches the light-outceasing unit 2 at a relatively small angle.

[0025] Furthermore, the light-incident unit 1 can focus the light to a point in the vertical direction, and the focal point of the light-emitting unit 2 is located at this convergence point. At this time, the light-emitting unit 2 can collimate the received light in the vertical direction. Since the illumination angle requirement of the car headlight is relatively small in the vertical direction, by colliding the light in the vertical direction, the illumination angle requirement in the vertical direction can be met, and the uniformity of illumination can be ensured.

[0026] Multiple light-incident units 1 are arranged vertically, and multiple light-outcrystal units 2 are also arranged vertically.

[0027] The light incident unit 1 has a curved outline on the vertical plane, and the light incident unit 1 is a strip structure formed by extending the outline along its normal direction.

[0028] The outline of the first diffusion pattern on the vertical plane is consistent with the outline of the incident light unit 1. The guide line of the first diffusion pattern in the horizontal plane is a curve, and the curve is convex to the negative direction of light emission, so as to diffuse the light in the horizontal direction.

[0029] In this embodiment, the first diffusion pattern of the light incident unit 1 has a diffusion effect in the horizontal direction. The diffusion of light by the first diffusion pattern increases the lighting angle in the horizontal direction, thus meeting the requirement of large-angle lighting in the width direction.

[0030] By setting multiple first diffusion patterns on the light-incident unit 1, the emission angle of the light received by the light-incident unit 1 in the horizontal direction is adjusted, thereby improving the uniformity of illumination in the horizontal direction.

[0031] The outline of the light-emitting unit 2 in the vertical direction is a curve, the outline of the light-emitting unit 2 is convex to the positive light-emitting direction, and the outline of the light-emitting unit 2 extends along its normal direction to form a strip structure.

[0032] In this embodiment, the light-emitting unit 2 has a focusing effect on light at least in the vertical direction. This allows light rays with a diffusion angle in the vertical plane to be focused at a certain angle after passing through the light-emitting unit 2, thus improving the utilization rate of the light within the desired light distribution area. More preferably, the outline of the light-emitting unit 2 in the vertical direction is a curve with a focal point, which can collimate the received light in the vertical direction to improve the uniformity of illumination. In the horizontal direction, since the light-emitting unit 2 has a strip-shaped structure, it can receive a large amount of light refracted by the light-incident unit 1, ensuring a high light reception rate.

[0033] The light incident unit 1 includes multiple light incident components, which are arranged horizontally. The outline of the light incident components on the vertical plane is a curve, and the guide line of the light incident components in the horizontal direction is also a curve.

[0034] In this embodiment, the light-incident unit 1, composed of multiple light-incident components, has a diffusion effect in the horizontal direction, so as to adjust the light emission angle after the light passes through the light-emitting unit 2 in the horizontal direction and improve the uniformity of illumination.

[0035] The light-incident component is provided with multiple second diffusion patterns. The outline of the second diffusion patterns on the vertical plane is consistent with the outline of the light-incident component. The multiple second diffusion patterns are arranged along the guide line of the light-incident component.

[0036] In this embodiment, the uniformity of illumination is further improved by setting a second diffusion pattern on the light-incident component.

[0037] The light-emitting unit 2 includes multiple light-emitting components, which are arranged horizontally. The outline of the light-emitting components in the vertical direction is curved and convex to the light-emitting direction. The guide line of the light-emitting components in the horizontal direction is also curved and convex to the light-emitting direction.

[0038] In this embodiment, the light-emitting unit 2, composed of multiple light-emitting components, gathers the light at a certain angle in a horizontally divided area, so that the light is refracted within the required light emission angle, thus ensuring the utilization rate of the light.

[0039] The horizontal and vertical directions mentioned above are not fixed directions, but only define the positional relationship between them. During the assembly process, they can be adjusted according to the angle of the headlights.

[0040] A vehicle lamp comprising a miniature optical system, including any miniature optical system suitable for signal light functions.

[0041] A vehicle including headlights containing a miniature optical system.
