Problems solved by technology

Conventional lens illumination spot is circular, when used as projected lighting for cylindrical buildings, part of the light is blocked by the cylindrical buildings themselves and cannot be used, resulting in light loss
In the prior art, there are other ways to realize the ring-shaped spot, but the product structure and the number of product combinations are relatively complicated and the cost is relatively high
[0003] The existing patent document CN207778336U discloses a lens capable of projecting an arc-shaped spot. Although the patent also discloses a lens for projecting an arc-shaped spot, the patent does not point out how to realize the arc-shaped spot structurally. This patent mainly solves The technical problem is that the existing lens structure is complex, the assembly or disassembly is unchanged, and the light transmission effect of the lens is poor.

Abstract

A semi-arc-shaped light spot lens is used for containing an LED lamp bead and comprises a lens body, a first groove with a downward opening is formed in the bottom of the lens body, the LED lamp bead is arranged in the first groove and located at the bottom, and a first arc-shaped reflecting face and a second arc-shaped reflecting face are arranged on the side face of the lens body. The top of the lens body is evenly divided into a semicircular plane and a semicircular annular free-form surface, the annular free-form surface forms a second groove with an upward opening, the plane is located above the first arc-shaped reflecting surface, and the annular free-form surface is located above the second arc-shaped reflecting surface. According to the semi-arc light spot lens, light spots can irradiate around a cylindrical building, and the light utilization rate can be increased; and the lens can be realized by adopting one single lens, is easy to process and form, and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a semi-arc spot lens. Background technique [0002] Lenses are mostly used for outdoor landscape lighting, mainly for projection lighting of trees and cylindrical buildings. Conventional lens illumination spot is circular, and when used as projection lighting for cylindrical buildings, part of the light is blocked by the cylindrical buildings themselves and cannot be used, resulting in light loss. In the prior art, there are also other ways to realize the annular light spot, but the product structure and the number of product combinations are relatively complicated and the cost is relatively high. [0003] The existing patent document CN207778336U discloses a lens capable of projecting an arc-shaped spot. Although the patent also discloses a lens for projecting an arc-shaped spot, the patent does not point out how to realize the arc-shaped spot structurally. This patent mainly so...
