A novel LED lamp light distribution structure is characterized by comprising a lens used for refracting a light source and a plurality of LED lamps arranged on the periphery of the lens, wherein luminous surfaces of the LED lamps are tightly attached to the outer edge of the lens, and accordingly light rays emitted by the LED lamps can shoot into the lens from the outer edge of the lens; the luminous surface of the lens is covered with a light uniformization plate. The lens is a concave lens or a convex lens. The novel LED lamp light distribution structure has the advantages that the structure is simple, assembly is convenient, production cost is low and market competitiveness is improved; the light rays shoot in from the side wall of the lens, the propagation path of light is changed, the light rays can be refracted and propagated in the lens many times, and thus the distributed light rays are more uniform, softer and not dazzling; the convex lens is provided for scattering light distribution so that the irradiation range of the light rays distributed by the structure can be wider; the concave lens can be used for condensation light distribution, so the distributed light is better gathered together and brighter and is suitable for searchlights and the like.
