[0035] See also Figures 1 to 4 A pattern display structure of a light guide plate 22 for a vehicle lamp according to a specific embodiment of the utility model comprises a light guide 2 and a light guide bracket 3, wherein the light guide 2 is arranged on the light guide bracket 3, the light guide 2 comprises a light guide body 21, a light guide plate 22 and a bending portion of the light guide 2, a light incident surface 211 of the light guide body 21 is used to receive incident light, when the incident light enters the light guide body 21, the incident light is then emitted through the light guide body 21 and emitted toward the bending portion of the light guide 2, the bending portion of the light guide 2 is suitable for receiving the incident light and reflecting it to the light guide plate 22, a plurality of light guide microstructures 221 are arranged on the side of the light guide plate 22 facing the light guide bracket 3, the incident light passes through the light guide plate 22 and is irradiated to the light guide microstructure 221, and is uniformly emitted under the action of the light guide microstructure 221, and then the uniformly emitted light is reflected to the front side of the light guide plate 22 to form different optical concave patterns and make the light emission effect more diverse.

[0036] Specifically, a transverse diffusion pattern is provided on the periphery of the light guide body 21. When the incident light hits the diffusion pattern provided on the periphery of the light guide body 21 and is emitted, the diffusion pattern can disperse the light emitted from the light guide body 21 and enable the incident light to be evenly emitted to the bending part of the light guide 2, thereby forming a uniform light output effect.

[0037] More specifically, one side of the light guide bracket 3 facing the light guide body 21 is not polished to form a diffuse reflection structure. Therefore, with the cooperation of the light guide body 21 provided with a diffusion pattern, the light can emit more diffuse reflection, thereby improving the utilization rate of the light emitted by the light source 1 and meeting the requirement of uniform light output.

[0038] Specifically, one end of the light guide bending portion 23 is connected to the light guide body 21 , and the other end is connected to the light guide plate 22 , so that the incident light entering the light guide body 21 can be reflected again to the light guide plate 22 and then emitted to form an optical pattern.

[0039] See also Figures 5 to 7The light guide microstructure 221 includes a plurality of concave optical pattern monomers. After the incident light passes through the plurality of concave optical pattern monomers provided on each light guide microstructure 221 and is emitted toward the front surface of the light guide plate 22, an optical pattern composed of the light guide microstructures 221 is formed. It should be noted that the shapes of the plurality of concave optical pattern monomers are not fixed so as to be able to reflect the light, and can be formed into a variety of patterns such as triangles, circles, stripes, letters, etc. according to the requirements of the appearance shape, thereby forming different optical patterns.

[0040] Specifically, the light guide bracket 3 is arranged in parallel with the light guide 2 with a gap of a set length therebetween, the gap being maintained at about 1 mm, and the side of the light guide bracket 3 facing the light guide plate 22 is polished.

[0041] More specifically, the display structure also includes a decorative ring 4, which can be selectively arranged on the side of the light guide plate 22 facing the light emitting surface 222 and forms a shielding surface, so as to be able to shield the light emitted through the light guide microstructure 221, thereby making the light emitting effect more layered. Therefore, by combining the uniform light guide of the light guide body 21 and the focusing reflection principle of the light guide microstructure 221, a uniform and efficient light emitting effect of the lamp is achieved, and at the same time, the variable concave optical pattern monomer of the light guide microstructure 221 is used to form different light emitting structural features, and under the shape setting of the decorative ring 4, a more layered visual light emitting effect is formed. Moreover, the overall structure only uses the principle of multiple reflections of the light guide body 21 to achieve a light emitting effect with fewer parts and more shapes, effectively saving manufacturing and processing costs, and making the light emitting effect more diverse.

The vehicle lamp includes a light source 1, which is arranged on one side of the light guide body 21 to emit incident light to the light incident surface 211 of the light guide body 21. The incident light is emitted to the light guide bending portion 23 through the light guide body 21, and then irradiated to the multiple light guide microstructures 221 opened on one side of the light guide plate 22 through the light guide bending portion 23, and then reflected to the front side of the light guide plate 22 to form a light emitting effect.
