[0020] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0021] Aiming at street lamp installation scenarios, the utility model provides a lighting street lamp that combines an LED light source, a sunshade, and a peanut-shaped lens, so that the lighting lamp using the LED as the light source can meet the road installation scenario.

[0022] In an embodiment of the present utility model, Figure 1 This is a structural schematic diagram provided according to the specific structure of a high-efficiency LED lighting street lamp of the utility model, such as Figure 1 As shown, the utility model comprises: a lamp housing 1, a lamp board 3, a lens assembly 4 and a light shield assembly 5, wherein the lamp board 3, the lens assembly 4 and the light shield assembly 5 are sequentially installed in the lamp housing 1 from the inside to the outside.

[0023] The LED lamp beads 31 are evenly arranged on the lamp board 3, and the lens assembly 4 is provided with a lens 41 corresponding to the LED lamp beads 31. The lens 41 is used to change the light emitted by the LED lamp beads 31 from a Lambertian distribution to a batwing distribution. The sunshade assembly is provided with a shading curved surface 51 corresponding to the lens 41.

[0024] In one embodiment of the present utility model, the edge of the lens assembly 4 is provided with a sealing groove 42, and a waterproof ring 2 is provided in the sealing groove 42, wherein Figure 2 The top of the waterproof ring 2 and the sealing groove 42 shown are round so as to better fit the lens, and the bottom is an inverted trapezoid so as to prevent the waterproof ring 2 from falling off. The reinforcement at the bottom can better play a waterproof role.
