Compared with the prior art, the utility model improves the prior lens for the street lamp, the semi-ellipsoidal lens body is arranged on the base, the surface curvature of the prior hemispherical optical lens can be changed by utilizing the semi-ellipsoidal structure, and the optical coupling behavior of the whole lens can be changed when the surface curvature is changed, so that the light extraction efficiency can be improved; the bottom surface of the lens body is provided with the triangular-pyramid-shaped main groove, the notches of the main groove are provided with the two symmetrically-distributed second grooves, and the main groove is used as the light incident surface of the lens, so that light rays can be ensured to be irradiated into the lens body from the inner side surface of the main groove, and simultaneously, the light rays can be irradiated from the curved surface of the lens body by matching with the frosting layer on the bottom surface of the base, and the light emitting efficiency is further improved; the second groove and the main groove are arranged in the triangular pyramid shape, so that the incident angle of light rays can be adjusted, the light rays can be output from each surface of the lens body, the illumination area of the street lamp using the lens is increased, and the street lamp can be well suitable for the road conditions of three lanes; both ends through at main recess are equipped with radius angle and first recess respectively, utilize radius angle and first recess for the light of perpendicular incidence main recess can be accomplished the illumination of first recess outside direction and come, has further improved the illumination effect. In addition, the inner bottom surface of the main groove is arranged to be inclined, and the inclined surface can be used for further distance of light rays, so that the light rays are gathered towards the first groove as far as possible, and the light emitting effect is improved; through being equipped with two mounting holes on the base, utilize the mounting hole also to provide fixed space for the mounting that just is in the same place lens and the lamps and lanterns fixed plate of installation change lens when can be to the installation location of lens to reduce the damage to lens in the installation, made things convenient for the installation. Therefore, the utility model not only can improve the irradiation area, but also has the advantages of high light emitting efficiency, good illumination effect and convenient installation.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.
Examples are given. The street lamp lens for the three lanes is formed as shown in figures 1 to 7 and comprises a base 1, wherein a semi-ellipsoidal lens body 2 is arranged on the top surface of the base 1; a main groove 3 in a triangular pyramid shape is arranged in the middle of the bottom surface of the lens body 2, and a notch of the main groove 3 is positioned on the bottom surface of the base 1; one end part of the main groove 3 is rounded, and the other end part is provided with a hemispherical first groove 4; two symmetrically distributed second grooves 5 are arranged between the fillet and the first groove 4, and each second groove 5 is arranged at the notch of the main groove 3; and a frosted layer 6 is arranged on the bottom surface of the base 1.
The inner top surface of the main groove 3 is arranged in an inclined shape, wherein the distance between the end part of the main groove 3 provided with the fillet and the bottom surface of the base 1 is smaller than the distance between the end part of the main groove 3 provided with the first groove 4 and the bottom surface of the base 1; two diagonally distributed mounting holes 7 are formed in the base 1, and the depth of each mounting hole 7 is the same as the thickness of the base 1; the two mounting holes 7 are respectively arranged at two sides of the main groove 3; the main groove 3 and the first groove 4 form a triangular pyramid structure; the width of the main groove 3 gradually increases along the direction of the rounded corner toward the first groove 4.
