By setting the lens into a tower-shaped structure both inside and outside, the problems of color separation and glare can be effectively prevented, and the light emitted by the lamp body can be scattered, thereby reducing chromatic dispersion, and further making the light emitted by the lamp body more layered to adapt to the eyes and avoid discomfort in the eyes.

[0018] In one embodiment, in order to fully disperse the light, a frosted layer (not shown in the figure) is provided on both the inner surface and the outer surface of each transmissive layer 11.

[0019] In one embodiment, each transmissive layer 11 includes a first transmissive portion 111 and a second transmissive portion 112 integrally connected to the first transmissive portion 111. The outer diameter of the upper end of the first transmissive portion 111 is greater than the outer diameter of its lower end, and the upper end and the lower end of the first transmissive portion are smoothly transitioned. The outer diameter of the second transmissive portion 112 decreases from the upper end to the lower end. In one embodiment, the second transmissive portion 112 can be an inverted frustum structure, and the second transmissive portion 112 is disposed below the first transmissive portion 111. The sizes and structures of the contact surfaces between the first transmissive portion 111 and the second transmissive portion 112 of each transmissive layer 11 are the same. The outer diameter of the upper end of the first transmissive portion 111 of each transmissive layer 11 is greater than the outer diameter of the upper end of the first transmissive portion 111 of the upper layer. A chamfer 13 is provided on the outer periphery of the upper end of the first transmissive portion 111 of each transmissive layer 11.

By providing a frosted layer, the light can be fully dispersed. By providing insertion posts, the connection between the lens and an external lamp body can be facilitated, greatly facilitating the replacement of the lens.
