Optical stereoscopic lens

Abstract

The invention discloses an optical stereoscopic lens. The optical stereoscopic lens is arranged on a lamp plate in a covering mode, the lamp plate comprises an aluminum base plate and integrated LED light sources, wherein the integrated LED light sources are evenly arranged on the aluminum base plate, and a plurality of parallelly-arranged stereoscopic lens units are arranged on the upper surface of the optical stereoscopic lens; and each stereoscopic lens unit comprises a triangular protruding part and a plurality of semispherical protruding parts, the semispherical protruding parts of each stereoscopic lens are evenly distributed on the same side of the corresponding triangular protruding part and in contact with the corresponding triangular protruding part, arc-shaped sunken parts corresponding to the integrated LED light sources in a one-to-one correspondence mode are arranged on the lower surface of the optical stereoscopic lens, and the positions of the arc-shaped sunken parts correspond to the joints of the triangular protruding parts and the semispherical protruding parts. According to the optical stereoscopic lens, the problem that in the prior art, light source emitted by an integrated SMD chip can generate a layering phenomenon after passing through a lens is solved, light spot illumination is uniform and symmetrical, no zebra line and combined line appears, and meanwhile, stereoscopic lens baffle parts of the triangular protruding parts distribute light to needed irradiation directions effectively, so that the effective use ratio of the light is enhanced.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to an optical three-dimensional lens. Background technique [0002] In the prior art, in the design of LED lamps for general large polarized area lighting or multi-lane road lighting, in order to achieve the purpose of simplifying optical design, LED light sources imitating lumen LENS with convex primary optics are usually used for design. However, considering the cost performance of the lighting system, the cost performance of the SMD lighting system has an absolute advantage. The design of the SMD lighting system is relatively complicated, and multiple combined SMD chips are required. The light source emitted by the SMD chip will be delaminated after passing through the lens, and then problems such as uneven illumination of the spot, zebra crossing and joint line will appear. At the same time, the distribution of light is also affected. The optical limitation of multiple c...
