In the technical field of illumination, because the LED light source has the advantages of low energy consumption, strong applicability, high stability, short response time, multicolor luminescence and the like, the LED light source gradually replaces the traditional light source and is widely applied to various illumination occasions. With the development of LED lighting application, landscape lighting wall washing lamps are more and more widely applied, almost all around every corner of a city, various lamps are installed on the outer surface of an outdoor building, and a plurality of colors are added for life and environment.

The lens is used as a main accessory of the lamp, can realize different lighting effects, and is commonly used for lighting irradiation of buildings at night, such as landscape buildings, villa communities, parks and other landscape decorations. With the use of LED night scene lighting becoming more and more widespread, the glare pollution caused by the glare feeling of people due to the reflection of mirror buildings and unreasonable light has also attracted more and more attention. At present, most of ways for improving lighting light generating dizziness are to add a light shielding plate to a lamp or mount the lamp obliquely.
