Optical structure capable of achieving bright visual effect Technical Field The utility model relates to the technical field of optical design, in particular to an optical structure capable of achieving a bright visual effect. Background With the rapid development of the automobile industry, the optical scheme and lighting effect of the automobile lamp have more diversified and unique design requirements. In recent two years, the bright effect of lighting a starry sky is that the eyes are first lightened due to the lighting specificity, and more attention of a host computer factory is received, so that a plurality of vehicle factories provide bright lighting effect requirements for some functions of the vehicle lamp. However, because of the particularly high processing requirements and difficulties of the patterned surfaces, some optical solutions are subject to heavy difficulties in the initial design. In the past, the scheme generally adopts LEDs to directly irradiate and the bright effect patterns are arranged at the light emitting surface, and the scheme often limits the plasticity of the mounting space of the car lamp. Disclosure of utility model The utility model aims to solve the technical problem that the LED is directly projected to the light-emitting surface to limit the plasticity of the mounting space of the car lamp, and provides an optical structure capable of achieving a bright visual effect by lighting. The technical scheme adopted by the utility model for solving the technical problems is that the optical structure capable of realizing bright visual effect comprises a thick-wall part, wherein the width direction of the thick-wall part is set to be the X direction, the height direction of the thick-wall part is set to be the Z direction, and the length direction of the thick-wall part is set to be the Y direction; The thick-wall member comprises at least one first reflecting surface, wherein the first reflecting surface is positioned at one end of the thick-wall member, special patterns are at least partially arranged on the inner side of the first reflecting surface, light rays emitted to the first reflecting surface are randomly reflected by the special patterns, therefore, the light rays are randomly irradiated to the first reflecting surface at any angle, the reflecting angles of the special patterns are different, the bright visual effect of lighting is achieved, and the limitation of the position arrangement of the LEDs is reduced by the first reflecting surface, so that the plasticity of the mounting space of the vehicle lamp is improved. The special pattern comprises a plurality of irregular polygons, wherein the irregular polygons are randomly distributed in a non-overlapping mode, the areas of the irregular polygons are different in size, and therefore the plurality of irregular polygons are arranged in a connected mode to form a special reflecting portion. The special patterns comprise a plurality of rice-shaped patterns, the rice-shaped patterns are arranged in a disordered manner, the center points of the rice-shaped patterns are not overlapped, the rice-shaped patterns and the adjacent rice-shaped patterns are arranged in a staggered manner, therefore, the distribution density of the rice-shaped patterns on the first reflecting surface is different, the rice-shaped patterns and the adjacent rice-shaped patterns are staggered to form special reflecting portions, when light irradiates the special reflecting portions at any angle, the reflecting angles are different, and the bright visual effect of lighting is achieved. Further, the reflecting surface is vacuum coated, so that diffuse reflection can be performed on the inner side of the reflecting surface. Further, the overall shape of the first reflecting surface is a plane, a paraboloid, a hyperboloid or a free-form surface. Further, in order to ensure the integrity of the reflection degree, the end face of the first reflection surface intersects with a plane formed by the X direction and the Y direction, the intersection angle is an obtuse angle, and the first reflection surface is obliquely arranged upwards, so that the total reflection of the first incident light ray by the first reflection surface is ensured.
