摘要
由于市場(chǎng)上光源的變革，LED光源以其優(yōu)越的性價(jià)比在各類光源中，脫穎而出，因此，有關(guān)LED的照明也成為如今的討論熱點(diǎn)，對(duì)于LED照明，就不得不提到將LED光源二次配光的偷家。內(nèi)外公路的建設(shè)或是改造都急需各種應(yīng)用條件下的路燈。先旨在開發(fā)一款高亮度的路燈，并猜想一種新的設(shè)計(jì)方法。該畢業(yè)設(shè)計(jì)課題結(jié)合本校光學(xué)系統(tǒng)設(shè)計(jì)方向，根據(jù)深圳市利科達(dá)光電有限公司設(shè)計(jì)需求以及2010級(jí)學(xué)生所學(xué)專業(yè)課程情況所定。通過本畢業(yè)設(shè)計(jì)，學(xué)生可掌握系統(tǒng)的工作原理，國(guó)際同行設(shè)計(jì)的發(fā)展現(xiàn)狀。利用所學(xué)軟件建立系統(tǒng)模型，進(jìn)行優(yōu)化、分析，基本達(dá)到掌握此類系統(tǒng)設(shè)計(jì)的基本方法和技術(shù)。

Abstract
Due to changes in the market source, LED light source with its excellent value for money in all kinds of light sources, come to the fore, the relevant LED lighting has become a hot discussion now for LED lighting, LED light source will have to mention the secondary distribution light to steal home. Highway construction or renovation inside and outside under the lights are in urgent need of a variety of application conditions. First to develop a high brightness of the street, and guess a new design approach. The graduation project combining optical system design direction of the school,According to Shenzhen likeda design requirements and 2,010 students learn professional courses given situation. Through this graduation, students can master the system works, status of development of the international peer design. Use what they have learned to build software system model to optimize the analysis, the basic design of such systems reach to grasp the basic methods and techniques.
