Taking the first light guiding pillar 1 as an example, since the first light inlet is located on the end surface of the first light guiding pillar 1, and the first light outlet is located on the side surface of the second light guiding pillar, after the light enters the first light guiding pillar 1 from the first light inlet, the light can be emitted from the first light outlet along a path similar to an L shape, but the light is linearly transmitted in the same medium, so that the light needs to be reflected or refracted by the first reflecting surface 11, and more light can be smoothly emitted from the first outlet. In this embodiment, the first reflective surface 11 is disposed obliquely, and the refraction direction faces the first light outlet. Specifically, the included angle formed by the first reflecting surface 11 and the axis of the first light guide column 1 is 40-50 °, in this embodiment, in order to make the reflection and refraction effects better, the included angle formed by the first reflecting surface 11 and the axis of the first light guide column 1 is 45 °.
