The embodiment provides a dual-function multiplexing thick-wall member optical structure, which comprises a light source 1 and a thick-wall member 2. In some embodiments, the light source 1 is an LED light bulb. The light source 1 includes a first light source 11 and a second light source 12, the first light source 11 includes a plurality of LED beads, the second light source 12 includes a plurality of LED beads, and the number of LED beads of both the first light source 11 and the second light source 12 may be the same or different.
The thick-wall member 2 is a block-shaped structural member formed by solid transparent materials, and the shape of the thick-wall member is designed according to the modeling of the car lamp, and can be an arc-shaped bar block, as shown in fig. 2. The following description will be made taking the thick-walled surface 2 as an arc-shaped bar as an example. The thick-wall surface 2 includes an incident surface 21, a total reflection surface 22, and an outgoing surface 23, wherein the total reflection surface 22 and the outgoing surface 23 are opposite ends of the thick-wall member 2, the outgoing surface 23 is an outer circumferential surface of the thick-wall member 2, and the total reflection surface 22 is an inner circumferential surface of the thick-wall member 2. The total reflection surface 22 includes a first total reflection surface 221 and a second total reflection surface 222, the first total reflection surface 221 and the second total reflection surface 222 form a V-shaped structural surface, and the vertex of the V-shaped structural surface is concave toward the light-emitting surface 23. The incident surface 21 includes a first incident surface 211 and a second incident surface 212, the first incident surface 211 and the second incident surface 212 are upper and lower end surfaces of the thick-walled workpiece 2, respectively, the first incident surface 211 is located above the first total reflection surface 221, and the second incident surface 212 is located below the second total reflection surface 222. In the above, total reflection means: light emitted by the LED light source enters the thick-wall member after being refracted through the incident surface, the total reflection principle is utilized at the total reflection surface, namely, when the incident angle is larger than a critical angle when the light enters the air from the medium, the light is totally reflected, the light propagation direction is changed, the light is enabled to continue to propagate in the medium and not to be refracted into the air, wherein the critical angle is arcsin (n 2/n 1), n2 is the refractive index of the material of the thick-wall member, and n1 is the refractive index of the air. The total reflection surface of the thick-wall member is obtained by calculating the direction of the light folded into the thick-wall member through simulation software, and the light after total reflection can be continuously transmitted towards the light-emitting surface along the horizontal direction.
The first light source 11 is disposed above the first incident surface 211, and the light of the first light source 11 enters the thick-wall member 2 through the first incident surface 211 and irradiates the first total reflection surface 221, the angle of the reflected light passing through the first total reflection surface 221 is changed, the light after the angle change propagates toward the center direction of the light emitting surface 23, and propagates out through the light emitting surface 23, so that the light emitting surface 23 is lightened. The first total reflection surface 221 is configured to reflect light toward the entire light-emitting surface 23. The second light source 12 is disposed below the second incident surface 212, and light from the second light source 12 enters the thick-wall member 2 through the second incident surface 212 and irradiates the second total reflection surface 222, an angle of the reflected light passing through the second total reflection surface 222 is changed, the light after the angle change propagates toward the center direction of the light-emitting surface 23, and propagates out through the light-emitting surface 23, so that the light-emitting surface 23 is lightened. The second total reflection surface 222 is configured to reflect light toward the entire light-emitting surface 23. The first light source 11 and the second light source 12 are independent light-emitting control elements, and the first light source 11 and the second light source 12 can emit light simultaneously, and when the two light sources emit light simultaneously, the light rays which are outwards diffused from the light-emitting surface 23 are mixed light rays.
According to the optical structure of the dual-function multiplexing thick-wall member, the light inlet surfaces of two different structures are designed according to different requirements of two functions through the single thick-wall member, so that the number of light sources and the light inlet surfaces of the two functions can be separately and independently designed, and the two functions can be shared.

Accordingly, the second total reflection surface 222 is formed with a second diffusion pattern 2220, and the second diffusion pattern 220 is also used to increase the diffusion angle of the light. Further, the light emitting surface 23 is formed with a third diffusion pattern 231, and the third diffusion pattern 231 is also used for improving the diffusion angle of the light, so as to achieve better lighting uniformity.
In some embodiments, the upper surface of the thick-walled member 2 is a stepped surface and is a first-stage step, and the first incident surface 211 is a raised surface of the stepped surface. The uniformity of light can be effectively improved by arranging the convex surface. In some embodiments, the lower surface of the thick-walled member 2 is a stepped surface, also a first step, and the second incident surface 212 is a raised surface of the stepped surface. The uniformity of light is effectively improved by arranging the convex surface.
