The isolation unit 2 is installed between the light transmission unit 1 and the light emitting unit 3 to prevent the occurrence of cross-light phenomenon.

[0034] Please combine Figure 3 and Figure 4The light transmission unit 1 includes a light incident end 11, a light emitting end 12 and a plurality of light guide columns 13. The light incident end 11 and the light emitting end 12 are respectively located at the two ends of the light guide column 13. The light emitting unit 3 is connected to the light incident end 11. The light emitted by the light emitting unit 3 is incident from the light incident end 11, passes through the light guide column 13 and then is emitted from the light emitting end 12, forming a complete light transmission route.

[0035] Specifically, the light incident end 11 includes a light incident surface 111, a fixing member 112 and a mounting beam 113. Figure 3 As shown, the light incident surface 111 is located at the outermost end of the light incident end 11, and the fixing member 112 is arranged on the light incident surface 111 and extends outward perpendicularly to the light incident surface 111. In this embodiment, the fixing member 112 is in the shape of a hook, which is used for detachable connection with the light-emitting unit 3. The fixing member 112 can be installed on each of the light incident surfaces 111, or the fixing member 112 can be installed on only a part of the light incident surfaces 111 while ensuring a stable connection. For example, in this embodiment, the fixing member 112 is installed only on the outermost light incident surfaces 111 on both sides. The mounting beam 113 connects a plurality of the light guide columns 13, and is located between the light guide columns 13 and the light incident surface 111. In this embodiment, the light transmission unit includes four light guides 13 and corresponding four light incident surfaces 111. Of course, in other embodiments, the number of the light guides 13 and the light incident surfaces 111 can be increased or decreased without restriction to meet different usage requirements. A mounting groove 114 is also provided between the mounting beam 113 and the light incident surface 111, and the mounting groove 114 is used to connect and fix with the isolation unit 2. The light incident end 11 is provided with two mounting grooves 114, which are respectively provided on the outermost light guides 13.

By changing the arc and arc length of the light guide 13, the angle α between the light incident end 11 and the light emitting end 12 can be adjusted, and the angle α is between 90° and 180°. Figure 5 As shown, in another embodiment, the light guide column 13 is in a straight line, so the light incident end 11 and the light emitting end 12 are located on the same straight line, and the angle α is 180°, which makes the light emitted by the light emitting unit 3 transmit along a straight line without changing the transmission direction. In actual use, the size of the angle α can be set according to needs.

Finally, snap the fixing part 112 on the light transmission unit 1 into the fixing groove 311 to complete the assembly of the light transmission unit 1, the isolation unit 2 and the light-emitting unit 3 to form an anti-cross-light guiding component.

[0048] Then, the assembled anti-cross-light light guide assembly is installed into the device 4. This embodiment takes a device with a rectangular shell as an example.
