[0081] First, see figure 1 , figure 2 and Figure 4 As shown, the first embodiment of the present invention provides a vehicle light device H with switchable far and low light shapes, which includes a light collecting unit 1 , a light emitting group 2 , a reference axis DL and a reference axis RL. In the first embodiment, the light collecting unit 1 may be a multi-reflector (Multi Reflector, MR) with multiple curvatures, which includes at least two curved surfaces with different curvatures, and the light collecting unit 1 has a first focal point 11. A second focal point 12, a focal point F, a horizontal axis 14, a vertical axis 15 and an optical axis 16. Next, the first focal point 11 , the second focal point 12 , and the light-collecting focus F are located on the same side of the light-collecting unit 1 . Thereby, the light source emitted by the light-emitting group 2 can be emitted towards the direction of the light-collecting unit 1 , and then the light source can be r...

[0099] First, see Figure 8 and Figure 11 shown by Figure 8 and figure 1 It can be seen from the comparison that the biggest difference between the second embodiment and the first embodiment is that the light collecting unit 1 used in the second embodiment is different from that in the first embodiment. What the light-collecting unit 1 of the second embodiment adopts is another kind of shape multiple reflection mirror, and it comprises at least two curved surfaces with different curvatures, and the light-collecting unit 1 has a first, second focal point (11,12) , a focal point F, a horizontal axis 14 , a vertical axis 15 and an optical axis 16 , the first and second focal points ( 11 , 12 ), and the focal point F are located on the same side of the light collecting unit 1 . The light source emitted by the first and second light emitting surfaces (212, 222) is emitted towards the direction of the light collecting unit 1, and then reflected by the reflector structure on the...

[0106] First, see Figure 12 , Figure 13 ,and Figure 16 shown by Figure 13 and Figure 8 and figure 1 Comparison shows that the biggest difference between the third embodiment and the aforementioned first and second embodiments is that the light collecting unit 1 of the third embodiment adopts a total internal reflection lens (Total internal reflection, TIR). It includes at least two curved surfaces with different curvatures, and the light collecting unit 1 has a first and a second focus (11, 12), a light collecting focus F, a horizontal axis 14, a vertical axis 15 and an optical axis 16, The first and second focal points ( 11 , 12 ), and the light-collecting focus F are located on the same side of the light-collecting unit 1 . The light sources of the light-emitting group 2 emit toward the direction of the light-collecting unit 1 , and the light sources will pass through the light-collecting unit 1 to emit after being reflected or refracted.
