Compared to the conventional spherical lens, a Fresnel lens by the lens divided into a series of concentric circles theoretically infinite number of lines (i.e., the Fresnel zone) to achieve the same optical effect, while saving the amount of material For these lines, the overall thickness of the lens is reduced; ordinary Fresnel convex lens is actually a continuous curved surface is truncated to a section of a discontinuous change of the curvature as the surface is finely divided, so look like a circle around the lines. Fresnel lenses may in fact be regarded as a series of prisms are arranged in a ring, wherein the relatively sharp edge, and the center of the convex surface is relatively smooth.
Note :If you need round Diameter 1100mm, please contact our service people.otherwise we will ship square 1100*1100mm. The stand is only for showing product, not for sale.
Application: Fresnel lenses for LED light source, serve to increase efficiency, improve the brightness effect, with respect to the same lens and LED lights, the focal length is different, how different distances arbitrary outgoing light angle, single or multiple lights an array of LED lights can be designed according to the requirements. For LED flood light, colorful spot lights, lighting, landscape, lights, a variety of lamps. Features: thin Fresnel lens structure, large size, any shape of cutting, excellent light transmittance geometric Traditional multi-lens advantage, its weight is less than a convex lens, suitable for many occasions.
（For standard circle groove fresnel lens only）
