as shown in fig. 7, on the outer side of the lens 1, the even thickness middle region 1a and the gradually thickened edge region 1b are connected to form an outwardly convex curved surface; the lens 1 is inboard, and even thickness middle region 1a is outside convex cambered surface, and gradually thick limit district 1b is the cambered surface that extends from even thickness middle region 1a to the inboard, and this arc curved surface is convex arc. The thickness of the lens 1 at the position with the maximum thickness of the arc-shaped curved surfaces at the two sides of the lens 1 can be kept unchanged, and the thickness can be increased continuously.
As shown in fig. 10, the lens 1 is circular and includes a uniform thickness middle region 1a having a uniform thickness and gradually thicker side regions 1b having gradually larger thicknesses, wherein the gradually thicker side regions 1b are located on both left and right sides of the uniform thickness middle region 1 a.
The light emitted by the light source 7 is divergent, the light is gathered into approximately parallel light through the reflecting cup 2, the parallel light irradiates the front lens 1, when the light irradiates the uniform thickness middle area 1a part with uniform thickness of the lens 1, the uniform thickness middle area 1a part with uniform thickness of the lens 1 can not refract the light, and the light is directly irradiated to the front; when light irradiates the part of the gradually-thickened edge area 1b with gradually-increased thickness of the lens 1, the arc surface part of the gradually-thickened edge area 1b with gradually-increased thickness can refract the light, so that the light is diffused towards two sides, and a wider visual field range is provided for a rider.
