Background technology
LED has the advantages such as energy-saving and environmental protection, as lighting source, has entered various fields.The advantages such as energy consumption is low owing to having for LED street lamp, life-span length, non-secondary pollution have very large development potentiality, also there are on the market at present a lot of LED street lighting products, but mostly there is the shortcomings such as illumination zone is wideless, light efficiency utilization rate is not high, road surface intensity of illumination skewness.Therefore, LED street lamp being carried out to secondary optics processing has very great significance to improving street lamp performance tool.The mode of processing for LED street lamp secondary optics at present mainly concentrates on LED is installed additional to optically focused reflector and two aspects of secondary light-distribution lens, but due to LED light intensity lambertian distribution, while adopting optically focused reflector, street lamp upright position can form compared with high light spot, can not obtain the light distribution compared with high evenness.And the secondary light-distribution lens occurring at present concentrates in the application of the sharp lamp pearl of the imitative lumen He Fang section of branch mostly, mainly with single LED lamp pearl, single-curved surface, be designed to main, if be applied on the street lamp of many LED lamp pearl, between secondary optical lens and the former luminous intensity distribution of lamp pearl, easily form light disorderly, the utilization ratio of luminous energy is lower.
Utility model content
The utility model provides a kind of LED street lamp lens module, adopts the problem of the LED street lamp of multi-wafer or many SMD light sources with can not being applicable to of solving that prior art exists.
The utility model solves the technical scheme that its technical problem adopts:
A LED street lamp lens module, is comprised of upper composite curvature face and lower composite curvature face, and upper composite curvature face and lower composite curvature face form light distribution curved surface, and LED light-emitting particles is positioned at the groove that lower composite curvature face forms.
Above-mentioned lower composite curvature face bottom centre arranges high light small sphere of exterior rearview, and the strong beam lighting angle of high light small sphere of exterior rearview and two LED light-emitting particles matches, and the surrounding of high light small sphere of exterior rearview is frosting curvature surface, plays the effect of auxiliary optically focused.
Above-mentioned upper composite curvature face and lower composite curvature face are made by the anti-UV polymer plastic glue material of high transmission rate.
Above-mentioned upper composite curvature face and lower composite curvature face adopt the method for nonimaging optics variational integral geometry optimization and free three-dimensional surface cutting, are built into the optical texture that given luminous intensity distribution is rectangular light spot.
LED street lamp lens module operation principle of the present utility model is, the light part that LED light source sends is by the high light small sphere of exterior rearview of lower composite curvature face, a part is by the frosting of lower composite curvature face, afterwards by and upper composite curvature face between refraction, the reflection of optical texture reach the needed rectangular light spot of street lighting.
The utility model light distribution curved surface selects the anti-UV polymer plastic glue material of high transmission rate to make, use the method for nonimaging optics and free three-dimensional surface cutting, by professional optical design software, according to the once light-distribution curve condition of the permutation and combination of LED module and lamp pearl, design many toroidal lens module, when LED light process optics of lens curved surface, light can reflect and optically focused in anti-life, penetration optically focused is used in the design of lens in dead ahead, peripheral curved surface can all be collected sidelight and reflect away again, overlapping the most perfect light utilization and the beautiful hot spot effect of just can obtaining of these two kinds of light, avoid to greatest extent again the formation of light disorder between the former luminous intensity distribution situation of secondary optical lens and lamp pearl, improve the utilization ratio of luminous energy.
