total reflection surface

4 and 5, LED light source 3 is installed to total reflection surface 4 upside, install LED light source 3 on the total reflection surface 5, total reflection surface 4, thick wall side 8, play plain noodles 9 constitute thick wall spare, thick wall spare is the bar structure, thick wall spare comprises little curvature region 1, big curvature region 2, LED light source 3 arranges on little curvature region 1 and evenly arranges on the horizontal direction, LED light source 3 arranges on big curvature region 2 and arranges according to similar permutation and combination mode on the horizontal direction, LED light source 3 is perpendicular to the income plain noodles of total reflection surface 4 respectively, the total reflection surface 4 occupies half the area of the rear surface of the thick-walled member, and the total reflection surface 5 occupies the other half of the area of the rear surface of the thick-walled member. The arrangement distance of the LEDs in the small-curvature region 1 is 10-18 mm, the arrangement of the LED light sources 3 is uniform in the region with small curvature in the horizontal direction, and the arrangement distance of the LEDs is 10-18 mm. The permutation and combination mode is similar to an arithmetic progression. The LED light source is divided into an LED light source with a steering function and an LED light source with a daytime running and position indicating function, and the position function is realized by reducing the current of the LED light source with the daytime running function. The total reflection surface 4 is provided with a checkered pattern. The thickness of the thick wall side surface 8 is more than or equal to 15 mm. The thick wall side 8 is a plane with a draft angle. The connecting surface of the thick-wall total reflection surface 4 is provided with upper and lower diffusion pattern surfaces.
