Detailed ways

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present utility model, rather than limiting the protection scope of the present utility model.

As shown in FIG. 1 , a low-beam vehicle lamp for displaying whether the road surface is flat or not includes a vehicle lamp main body 1 . Connected lampshade 13, the car lamp main body 1 also includes a lens 15 and a light-transmitting panel 16 arranged in the housing, the lens 15 and the light-transmitting panel are sequentially located between the light-emitting element 12 and the lampshade 13, and the inside of the lampshade 13 The side is a non-transparent criss-cross three-dimensional grid. When in use, low beam headlights project an orthographic grid on the ground. When there are obstacles, potholes, or bumps on the ground, the projection pattern of the corresponding part will be distorted and changed, giving the driver an instant signal.

As shown in Figure 2, the lens 15 includes a mounting portion 21 and a convex portion 22, the mounting portion 21 and the convex portion 22 are integrally formed, the end surface of the mounting portion 21 away from the convex portion 22 is a plane, and the plane is an optical Plane, which conducts light; the end of the convex part 22 away from the mounting part 21 is a convex curved surface extending to the mounting part; a local slope 221 is formed on the surface of the convex curved surface close to the mounting part, and the slope 221 Extending toward the end of the convex curved surface away from the mounting portion 21 .

In this embodiment, the mounting portion 21 is preferably cylindrical, and the lens 2 is directly clamped and fixed in the lamp housing 1 through the mounting portion 21 during assembly.
