The first optical pattern 110 includes a first optical surface 111 and a second optical surface 112. The second optical element 200 includes a third light exit portion and a fourth light exit portion. Along the light exit direction of the light emitting system, the third light exit portion corresponds to the first light exit portion, and the second light exit portion corresponds to the fourth light exit portion. The third light exit portion is provided with a second optical pattern 210, and the second optical pattern 210 includes a third optical surface 211.

[0049] The light emitted by the light-emitting system enters the first optical element 100 as parallel light or nearly parallel light, and then part of the light is totally reflected by the first optical surface 111 and hits the fourth light emitting portion, and the other part of the light is refracted or directly emitted at the second optical surface 112 and hits the third light emitting portion; the light hitting the fourth light emitting portion is refracted by the fourth light emitting portion and then emitted in a direction away from the third light emitting portion to meet the requirements of the regulatory geometric visibility on one side of the headlight or the adjustment of a certain angle of other scenes, and the light hitting the third light emitting portion is refracted by the third optical surface 211 and then emitted in a direction away from the fourth light emitting portion to meet the requirements of the regulatory geometric visibility on the other side of the headlight or the adjustment of a certain angle of other scenes.

[0050] Specifically, combined Figure 2 ,by Figure 2 The dotted line in the figure is the boundary, the part on the right side of the dotted line is the first light exit portion and the third light exit portion, and the part on the left side of the dotted line is the second light exit portion and the fourth light exit portion.

[0051] Combine Figure 1, angle A is the deflection angle of the light emitted by the light emitting system relative to the incident direction after the light is totally reflected by the first optical element 100 and the first optical surface 111 and then emitted through or not through the first supporting surface 113 without entering the second optical element 200; the deflection angle of the light emitted by the light emitting system relative to the incident direction after the light is refracted by the first optical element 100 and the second optical surface 112 and then emitted without entering the second optical element 200 is smaller or 0, which is not shown in the figure; angle B1 is the angle of the light totally reflected by the first optical surface 111 deviating from the initial incident direction after the light is refracted by the fourth light emitting part, enters the second optical element 200 and is finally refracted and emitted from the surface of the second optical element 200; angle B2 is the angle of the light refracted or directly emitted by the second optical surface 112 deviating from the initial incident direction after the light is refracted by the second optical element 200 and the third optical surface 211, enters the second optical element 200 and is finally refracted and emitted from the surface of the second optical element 200.

[0052] By adjusting the microstructure of the first optical pattern 110 and the second optical pattern 210, that is, adjusting the angles and other parameters of the first optical surface 111, the second optical surface 112 and the third optical surface 211, the final emission direction of the light can be adjusted.

[0053] Compared with the prior art, the vehicle lamp disclosed by the utility model realizes the demand for the propagation of multiple angle light rays through the combined design of the first optical pattern 110 and the second optical pattern 210, improves the light efficiency, reduces the pattern area, avoids the main light emitting area of the vehicle lamp being occupied by a large area, and optimizes the static and lighting effects of the whole lamp.

[0054] Specifically, the first optical pattern 110 includes a plurality of prism structures arranged in parallel, and the first optical surface 111 and the second optical surface 112 are different side surfaces of the prism structures.

[0055] In an embodiment, in combination with Figure 3 The prism structure described above is a quadrangular prism structure (trapezoidal prism structure), and the circumferential direction thereof includes a first side surface, a second side surface, a third side surface and a fourth side surface connected in sequence, wherein the first side surface is opposite to the third side surface and connected with the first light emitting part, the second side surface is opposite to the fourth side surface, and the distance between the second side surface and the fourth light emitting part is smaller than the distance between the fourth side surface and the fourth light emitting part; the fourth side surface serves as the first optical surface 111 for total reflection of light, the third side surface serves as the second optical surface 112 for refraction or direct emission of light, and the second side surface, that is, Figure 3 The first supporting surface 113 in the above-mentioned structure can be used for direct emission or refraction of light. By adjusting the distance between the first side surface and the third side surface and the width of the third side surface, the intensity of the light reflected to the third light emitting part and the fourth light emitting part can be distributed.

[0056] In another embodiment, the above-mentioned prism structure is a triangular prism structure, and its circumference includes a fifth side surface, a sixth side surface and a seventh side surface connected in sequence end to end, wherein the fifth side surface is connected to the first light output portion, and the distance between the sixth side surface and the fourth light output portion is smaller than the distance between the seventh side surface and the fourth light output portion; the seventh side surface serves as the first optical surface 111 to perform total reflection of light, and the sixth side surface serves as the second optical surface 112 to refract or directly emit light.

[0057] Further, combined with Figure 3 A light exit gap 114 is provided between two adjacent prism structures. The first light exit portion at the position corresponding to the light exit gap 114 allows light to pass directly or refract through and enter the third light exit portion.

[0058] In one embodiment, the second optical pattern 210 includes a plurality of triangular prism structures arranged in parallel, and a circumferential side surface of the triangular prism structure serves as the third optical surface 211; specifically, Figure 3 One of the three circumferential side surfaces of the triangular prism structure is connected to the third light exit portion. Of the other two side surfaces, the one closer to the fourth light exit portion serves as the third optical surface 211, and the other serves as the second support surface 212 to maintain the triangular prism structure. In another embodiment, the second optical pattern 210 includes a plurality of parallel quadrangular prism structures, with the circumferential side surfaces of the quadrangular prism structures serving as the third optical surface 211.

[0061] In order to ensure the appearance of the headlight, along the light-emitting direction of the light-emitting system, the area of ​​the third light-emitting portion is greater than or equal to the area of ​​the first light-emitting portion, and the first optical pattern 110 can be hidden by the second optical pattern 210 to avoid the misalignment of the front and rear boundaries, which would cause poor static and lit visual effects.

[0062] Specifically, the first optical element 100 and the second optical element 200 can be made of colorless, red, gray, or other transparent PC (polycarbonate) and PMMA (polymethyl methacrylate); the first optical element 100 and the second optical element 200 can be flat or curved.

Figures 7-10 The first optical surface 111, the second optical surface 112 and the third optical surface 211 can be divided into multiple surfaces along the axial direction, and a series of different curvatures or elevation angles can be added to each of the divided surfaces individually or simultaneously to achieve deflection and diffusion of the light emission direction. Figure 7 and Figure 9 The optical path diagrams are respectively for raising the angle of the dividing surface of the first optical surface 111 and the second optical surface 112. Figure 8 and Figure 10 The optical path diagrams for curvature of the bisecting surfaces of the first optical surface 111 and the second optical surface 112 are shown. The curvature or elevation angle can be increased for convex optical surfaces or decreased for concave optical surfaces. The first support surface 113 and the second support surface 212 can be configured as either a planar or curved surface.
