[0019] As a technical improvement, a sealing layer 8 is provided around the lampshade where it contacts the lamp housing, and the sealing layer is made of waterproof rubber.

[0020] As a technological improvement, the lampshade includes a lampshade layer 91, a protective layer 92 disposed on the outside of the lampshade layer, and a nano-transparent heat-insulating coating layer 93 disposed on the inside of the lampshade layer.

[0021] like Figure 4 As shown, the protective layer includes an elastic polyurethane layer 921 and an aluminum-coated film layer 922.

[0022] As a technical improvement, a clip is provided inside the lamp housing, and one end of the lamp housing has a connecting end 3.

[0023] As a technological improvement, the thickness of the nano-transparent heat-insulating coating layer is 30-50 nm.

[0024] As a technological improvement, the inner lamp has multiple individual units, which can be rhomboid or rectangular, and are evenly distributed within the inner lamp.

[0025] This utility model is ingeniously designed and has a novel concept. It features two types of lamp bodies that are evenly distributed in the design, taking into account both the inner and outer aspects, which can improve the uniformity of the light shape. Moreover, its unique shape makes it a rare structure.

[0037] The optical element design of the turning light is adjustable structure, which automatically adjusts the distribution and intensity of the light according to the driving state of the vehicle (such as turning angle, vehicle speed, etc.), so as to ensure that clear warning signals can be provided in different scenes.

[0038] · Uniform illumination design:

[0039] · The LED array design with large area and high uniform illumination is adopted, the arrangement mode of the light source is optimized through the simulated annealing algorithm, and the uniformity of the illumination distribution of the vehicle lamp on the target surface is ensured.

[0040] · The light source array of the vehicle lamp adopts the staggered arrangement mode, the illumination uniformity is further improved, and the light spot and the shadow area are reduced.
