The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Referring to the attached drawings 1 and 2, the high-power LED street lamp lens comprises a main body, wherein the main body comprises two convex curved surfaces 10, the two convex curved surfaces 10 are connected into a whole through a concave curved surface 20, an LED cavity 50 is arranged at the bottom of the main body, a convex spherical surface 51 is arranged at the top of the LED cavity 50, the convex spherical surface 51 is opposite to the concave curved surface 20, and the main body is in a central symmetrical structure; the convex curved surface 10 and the concave curved surface 20 are aspheric curved surfaces.

The axial ends of the bottom of the main body are provided with barbs 30, and the barbs 30 are oppositely oriented. By adopting the structure, the lens and the LED are very convenient to package, the assembling time schedule can be effectively reduced, and the production efficiency is improved.

The bottom of the main body is provided with a packaging surface 40, and the packaging surface 40 is provided with a glue injection hole 41.
