LED lighting lenses assemblies are components used in LED lighting applications to direct the light output in a certain direction by using the Fresnel lens principle. They are composed of one or more lenses that are usually made from plastic or glass. Additionally, LED lighting lenses assemblies can be customized in a variety of shapes and sizes to help meet the specific needs of any application. By using different degrees of curvature and lens shapes, the light output can be accurately distributed and effectively concentrated. Furthermore, lenses assemblies can also be designed to help reduce the amount of direct light exposure for certain applications, such as medical or retail lighting.
