Plane lens for lamp

The utility model provides a plane lens for a lamp, which has the technical scheme that the plane lens comprises a lens, a plurality of micro-edge rings which incline towards the center and are used for refracting light to reduce the glare value of the lamp are arranged on one surface of the lens, the micro-edge rings are concentric with the lens, a plurality of convex points for homogenizing light spots are arranged on the other surface of the lens, and the convex points are arranged on the lens. Or the other surface of the lens is a frosted surface; according to the LED lamp, light spots can be eliminated, illumination light rays are homogenized, the light beam angle is controlled to deflect to an illumination area through refraction of the micro edge rings, light rays scattered outwards are restrained, and therefore the illumination effect of the lamp is effectively enhanced, and the glare value of the lamp is reduced. 本实用新型提供了一种用于灯具的平面透镜，其技术方案的要点是：包括有镜片，在镜片的一面上设有若干条向中心处倾斜的、用于折射光线降低灯具眩光值的微棱圈，微棱圈与镜片同心，在镜片的另
