Description

Anti-glare LED lamp based on polarized light reflection technology Technical Field The utility model relates to the technical field of illumination, in particular to an anti-dazzle LED lamp based on polarized light reflection technology. Background The existing LED lamp mainly relies on a diffusion plate for light homogenization to inhibit glare, but the single scheme has obvious limitations. The scattering mechanism of the diffusion plate can only reduce the direct brightness of the light source, but directional reflection glare generated on the smooth surface lacks the targeted inhibition capability. For example, in a showcase, light forms high-brightness light spots after being reflected by a glass showcase, so that observation of a showpiece is seriously disturbed, when a still is photographed, reflected light of metal or glass utensils often causes local overexposure to damage picture texture, and under a desk lamp, reflection of a desk surface aggravates visual fatigue. Therefore, it is necessary to provide an anti-glare LED lamp based on polarized light reflection technology to solve the above problems. Disclosure of utility model (One) solving the technical problems The utility model aims to provide an anti-dazzle LED lamp based on a polarized light reflection technology, so as to solve the problems in the background technology. (II) technical scheme The anti-dazzle LED lamp comprises a lamp shade, wherein an LED light source is arranged in the lamp shade, an anti-dazzle lens is arranged at a light outlet of the lamp shade, the anti-dazzle lens is composed of a diffusion plate, a polarizing film and a transparent plate which are stacked in sequence, the diffusion plate is positioned on one side of the polarizing film, which is close to the LED light source, a support frame is fixedly connected with the edge of the anti-dazzle lens, the support frame is rotationally connected with the lamp shade, a bolt is connected to the upper part of the support frame in a sliding mode, and a plurality of slots matched with the bolt are formed in the outer side of the lamp shade along the circumferential direction of the support frame.
