The present embodiment provides an optical lens 40, wherein the optical lens 40 has a strip-shaped structure, and the optical lens 40 has a length direction a, a width direction B and a thickness direction C.

During the process of transmitting the illumination beam from the light inlet groove 421 to the light outlet groove 431, at least part of the beam is transmitted to the reflecting wall 441 and reflected by the reflecting wall 441, so as to extend the optical path length of the illumination beam, so that the divergence degree of the illumination beam is higher.
Under the arrangement of the present embodiment, the optical lens 40 has a divergent effect on light, specifically, after the illumination beam enters the optical lens 40 through the light inlet groove 421, the illumination beam can be conducted onto the mirror surface of the optical lens 40 at least once and reflected, so as to increase the optical path length of the illumination beam. The inner hole 44 on the optical lens 40 has a reflecting wall 441, at least part of the illumination beam can be conducted to the reflecting wall 441 and reflected by the reflecting wall 441, so as to further prolong the optical path of the illumination beam, and the illumination beam is conducted to the light outlet groove 431 and away from the optical lens 40 after being folded for a plurality of times inside the optical lens 40, so that the illumination beam passing through the optical lens 40 is more uniform.
