Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figures 1 to 3 As shown, a vehicle lamp dimming structure includes: a dimming component 1, a light guide part 2 and a light output part 3, the dimming component 1 includes a first reflecting surface 11 and a second reflecting surface 12, the first reflecting surface 11 and the second reflecting surface 12 are arranged in parallel, the width of the first reflecting surface 11 and the second reflecting surface 12 are both 1.5 mm, the first reflecting surface 11 and the second reflecting surface 12 are both covered with aluminum film, and the first reflecting surface 11 and the second reflecting surface 12 are both provided with light distribution patterns; the first reflecting surface 11 and the second reflecting surface 12 are connected by a vertically arranged first connecting surface 13, the distance between the bottom end of the first reflecting surface 11 and the top end of the second reflecting surface 12 is 0.5 mm, and the distance is the distance from the vertical plane of the bottom end of the first reflecting surface 11 to the vertical plane of the top end of the second reflecting surface 12.

[0031] In this embodiment, the top of the first connecting surface 13 is connected to the bottom of the first reflecting surface 11, and the bottom of the first connecting surface 13 is connected to the top of the second reflecting surface 12. The first reflecting surface 11 is arranged at the upper left of the first connecting surface 13, and the second reflecting surface 12 is arranged at the lower right of the first connecting surface 13; the end of the second reflecting surface 12 away from the first reflecting surface 11 is connected to the horizontally arranged second connecting surface 14.

The plurality of light adjusting assemblies 1 can be connected through the second connecting surface 14 to improve the required light emitting surface height of the vehicle lamp. Since the light adjusting assembly 1 is similar to a ladder, the incident light is totally reflected on the first reflecting surface 11 and the second reflecting surface 12, and the light height after total reflection is reduced due to the height difference, so as to adjust the up and down light distribution and realize uniform light mixing.

As shown in Figure 1 , the solid arrow represents the light path of the present scheme, and the dashed arrow represents the light path of the existing scheme. The light is incident on the first reflecting surface 11 or the second reflecting surface 12.

[0035] As described above, the incident light is converged through the condenser 4 and then incident on the light adjusting assembly 1. The light totally reflected on the first reflecting surface 11 and the second reflecting surface 12 is emitted from the light emitting part 3 through the light guide part 2. Since there is a height difference between the first reflecting surface 11 and the second reflecting surface 12, the height of the emitted light is changed, so as to change the energy distribution of the light and realize uniform light mixing.
