Abstract

An LED street lamp lens module is composed of an upper composite curvature surface and a lower composite curvature surface which form a light distribution curved surface, and LED luminous particles are placed in a groove formed by the lower composite curvature surface. The light distribution curved surface is made of high luminousness anti-UV polymer plastic materials, the methods of nonimaging optics and free three-dimensional surface cutting are used, a multi-curved-surface lens module is designed according to the permutation and combination of a LED module and the first time distribution curve flux condition of lamp beads through professional optical software, when LED light passes through a lens optical curved surface, the light can be reflected and condensed, a lens is designed to be arranged right ahead and condenses light in a penetrating mode, an outer peripheral curved surface can further collect and reflect all side light, the two kinds of light are overlapped so that the perfect light and a beautiful light spot effect can be obtained, the light disorder between secondary optical fibers and lamp bead original light distribution conditions is avoided to the largest extent, and the utilization efficiency of light energy is improved.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED street lamp lens module specially used for secondary light distribution of LED street lamps. Background technique [0002] LED has the advantages of energy saving and environmental protection, and has entered various fields as a lighting source. Due to the advantages of low energy consumption, long life, and no secondary pollution, LED street lamps have great potential for development. At present, there are many LED street lamp lighting products on the market, but most of them have limited lighting range and low light efficiency utilization. , Uneven distribution of light intensity on the road surface and other shortcomings. Therefore, the secondary optical treatment of LED street lamps is of great significance to improve the performance of street lamps. At present, the secondary optical treatment methods for LED street lamps mainly focus on adding a concentrating r...
