[0021] The light guide in this embodiment is mainly composed of a reflector 1, a light incident surface 2, a light emitting surface 3, a first reflective surface 4 and a second reflective surface 5. Figure 1 As shown, the reflector 1 is an irregular heptahedron structure, the light incident surface 2 is arranged on the lower bottom surface of the reflector 1, an LED lamp is arranged outside the light incident surface 2, and the light incident surface 2 is parallel to the light emitting surface of the LED lamp, so that the light emitted by the LED lamp can enter the reflector 1 from the light incident surface 2 for propagation, and the light incident surface 2 adopts a mirror structure, so that the light emitted by the LED lamp is less diffusely reflected when it enters the light incident surface 2, so as to reduce the loss of incoming light and improve the efficiency of incoming light, so that the light emitted by the LED lamp can better enter the reflector 1; the light emitting surface 3 is arranged on the top upper surface of the reflector 1, the light emitting surface 3 is parallel to the characters displayed on the interior of the vehicle, and the light emitting surface 3 The area covers the area of the characters displayed on the vehicle interior to ensure that the refracted light can cover the overall outline of the characters displayed on the vehicle interior, so that the brightness of the displayed characters is more uniform and there is no shadow; the first reflecting surface 4 and the second reflecting surface 5 are respectively the front and rear inner walls of the reflector 1, so that the light entering the reflector 1 can be reflected by the first reflecting surface 4 and the second reflecting surface 5 to the light emitting surface 3, and emitted by the light emitting surface 3 to illuminate the characters displayed on the vehicle interior, and the light is more uniform, thereby improving the display effect of the characters, and the reflector 1, the light incident surface 2, the light emitting surface 3, the first reflecting surface 4 and the second reflecting surface 5 are integrally formed to facilitate the production of the light guide.
[0022] Specifically, the light emitting surface 3 and the reflector 1 are mirror surfaces.
[0023] Specifically, the light emitting surface 3 and the reflector 1 are optical micro-patterned surfaces.
[0024] In the present embodiment, the light emitting surface 3 adopts a mirror structure to reduce the loss of light refracted from the light emitting surface and make the brightness of the light concentrated and bright. The reflector 1 adopts a mirror structure to improve the reflection efficiency of light in the reflector, thereby improving the efficiency of light use, so that the light output of the entire light guide is more uniform, the light is brighter, and the effect of character display is improved. In other embodiments, the light emitting surface 3 may also adopt an optical micro-patterned surface structure, so that the light is refracted from the light emitting surface with a minimum loss rate, and the refracted light is soft, not dazzling, and has uniform brightness. The reflector 1 may also adopt an optical micro-patterned surface structure to improve the utilization rate of light, increase the diffuse reflection of light, and further diffuse the light to make the light softer and not dazzling, thereby improving the effect of character display.
[0025] Furthermore, the included angle between the light emitting surface 3 and the light incident surface 2 is α, and the value of α is 8.2°.
[0026] In this embodiment, the angle between the light emitting surface 3 and the light incident surface 2 is designed to be 8.2° so as to achieve an optimal light reflection angle between the light emitting surface 3 and the light incident surface 2, thereby improving the utilization rate of light.
