市場(chǎng)上關(guān)注的還是整燈的光效，因此透鏡的設(shè)計(jì)要滿足三個(gè)方面的需求：一是透鏡的有效透光率;二是透鏡造型的創(chuàng)新性;三是透鏡與燈具配合的可視化效果。根據(jù)以上三點(diǎn)要求，市場(chǎng)上常見的透鏡設(shè)計(jì)主要有以下三種： </p> <p> <br /> </p> <p> 第一種透鏡采用外部直面鱗甲，出光面中心復(fù)眼設(shè)計(jì)。 </p> <p> <br /> </p> <p>

LED芯片（chip）理論上發(fā)光是360度，但實(shí)際上芯片在放置于LED支架上得以固定及封裝，所以芯片比較大發(fā)光角度是180度（大于180°范圍也有少量余光），另外芯片還會(huì)有一些雜散光線，這樣通過(guò)一次透鏡就可以有效匯聚chip的所有光線并可得到如180°、160°、140°、120°、90°、60°等不同的出光角度，但是不同的出光角度LED的出光效率有一定的差別（一般的規(guī)律是：角度越大效率越高）。 </p> <p> c. 一次透鏡一般用PMMA、PC、光學(xué)玻璃、硅膠等材料。 </p> <p> 二次透鏡 </p> <p> a. 二次透鏡與LED是兩個(gè)**的物體，但它們?cè)趹?yīng)用時(shí)確密不可分。 </p> <p> b. 二次透鏡的功能是將LED光源的發(fā)光角度再次匯聚光成5°至160°之間的任意想要的角度，光場(chǎng)的分布主要可分為：圓形、橢圓形、矩形。 </p> <p> c. 二次透鏡材料一般用光學(xué)級(jí)PMMA或者PC；在特殊情況下可選擇玻璃。 </p> <p> <br /> 安徽45W透鏡產(chǎn)品區(qū)分鑒別方法大燈透鏡的作用有哪些？</p><div

PMMA源自英文acrylic（丙烯酸塑料），化學(xué)名稱為聚甲基丙烯酸甲酯，俗稱有機(jī)玻璃，中國(guó)香港和中國(guó)臺(tái)灣習(xí)慣將PMMA稱為亞克力。該材料是一種開發(fā)較早的重要可塑性高分子材料，具有較好的透明性、化學(xué)穩(wěn)定性。塑料類材料，其擁有與PC材料一樣的特性，易成型、生產(chǎn)效率高、質(zhì)輕、抗摔，同時(shí)透光率高在3mm厚度時(shí)穿透率93%左右；缺點(diǎn)就是溫度不能超過(guò)85°，熱變形溫度92度。由于擁有較好的透光率、批量生產(chǎn)效益高、成本便宜，該材料被廣大應(yīng)用在各種光學(xué)透鏡中。 </p> <p> <br /> </p><p> 規(guī)格分類 </p> <p> 穿透式（凸透鏡） </p> <p> a. 當(dāng)LED光線經(jīng)過(guò)透鏡的一個(gè)曲面（雙凸有個(gè)曲面）時(shí)光線會(huì)發(fā)生折射而聚光，而且當(dāng)調(diào)整透鏡與LED之間的距離時(shí)角度也會(huì)變化（角度與距離成反比），經(jīng)過(guò)光學(xué)設(shè)計(jì)的透鏡光斑將會(huì)非常均勻，但由于透鏡直徑和透鏡模式的限制，LED的光利用率不高及光斑邊緣有比較明顯的黃邊； </p> <p> b．一般應(yīng)用在大角度（50°及以上）的聚光，如臺(tái)燈、吧燈等室內(nèi)照明燈具； </p> <p> 折反射式（錐型或杯型） </p> <p> b.也可在錐形透鏡表面做些改變，可設(shè)計(jì)成鏡面、磨砂面、珠面、條紋面、螺紋面、凸或凹面等而得到不同光斑效果。 </p> <p> 透鏡模組 </p> <p> a. 是將多個(gè)單顆透鏡通過(guò)注塑完成一個(gè)整體的多頭透鏡，按不同需求可以設(shè)計(jì)成3合1、5合1甚至幾十顆合一的透鏡模組；也可以把兩個(gè)單獨(dú)的透鏡通過(guò)支架組合在一起。 </p> <p> b. 此設(shè)計(jì)有效節(jié)省生產(chǎn)成本，實(shí)現(xiàn)產(chǎn)品品質(zhì)的一致性，節(jié)省燈具機(jī)構(gòu)空間，更容易實(shí)現(xiàn)“大功率”等特點(diǎn)。 </p> <p> <br /> 購(gòu)買品牌透鏡，歡迎聯(lián)系漢雷光電！</p><div

1、光器，這是調(diào)光技術(shù)很多年沒(méi)有發(fā)展的主要原因；LED又可以調(diào)光了，并且無(wú)論是亮還是暗光都是同樣的基本不變），這一點(diǎn)明顯優(yōu)于白熾燈的調(diào)光。 </p> <p> <br /> </p> <p> 2、可頻繁開關(guān)：LED的壽命是按點(diǎn)亮?xí)r算的，即便每秒鐘開關(guān)數(shù)千次也不影響LED壽命，在裝飾等需要頻繁亮滅的場(chǎng)合，LED燈有優(yōu)勢(shì)。 </p> <p> <br /> </p> <p> 3、顏色豐富：有正白光、曖白光、紅、綠、藍(lán)等各種顏色，無(wú)論是客廳里大燈旁用于點(diǎn)綴的小彩燈還是霓虹燈，都很鮮艷。 </p> <p> <br /> </p> <p> 4、發(fā)熱量低：像射燈，很多220V的射燈用不也幾天就壞掉就是因?yàn)榘l(fā)熱。12V鹵素 </p> <p> <br /> </p> <p> <br /> LED注塑模組的透鏡使用主流的光學(xué)設(shè)計(jì)軟件和機(jī)械建模軟件！浙江升級(jí)透鏡怎么樣</p><p style="text-indent:25px">品牌透鏡采購(gòu)，歡迎致電漢雷光電！浙江升級(jí)透鏡生產(chǎn)廠商</p><p> 1．LED注塑模組的透鏡使用主流的光學(xué)設(shè)計(jì)軟件和機(jī)械建模軟件。目前主要的設(shè)計(jì)軟件有：CodeV、ZEMAX、TracePro、ASAP、LighTools等；機(jī)械建模軟件有：Pro/E、UG、SOLIDWORKS等。這些軟件應(yīng)用便于交流和修改，可進(jìn)行光學(xué)仿真，不斷優(yōu)化而得到相應(yīng)的光學(xué)透鏡。 </p> <p> <br /> </p> <p> 2．LED注塑模組的透鏡在光學(xué)領(lǐng)域?qū)儆诰芘浼?，因此?duì)模具的精度要求極高，特別是透鏡光學(xué)曲面的加工精度要達(dá)到0.1μm。一般精度不高的模具加工設(shè)備是無(wú)法達(dá)到這么高的精度級(jí)別。對(duì)此透鏡廠家必須具有以下高精度模具的加工設(shè)備：超精密加工機(jī)（一般德國(guó)、日本的加工機(jī)精度是比較高的）、CNC綜合加工機(jī)、精密磨床、精密銑床、鉆床、CNC精密火花機(jī)、表面輪廓儀、干涉儀等。 </p> <p> 3．制造LED注塑模組的透鏡中精密的部件是光學(xué)模仁，優(yōu)先材料應(yīng)該是用模仁鋼材如：瑞典S136鏡面鋼，經(jīng)過(guò)熱處理到55°，完成粗胚，在粗胚上經(jīng)過(guò)鍍鎳處理后再用超精密加工機(jī)進(jìn)行曲面加工而得到。浙江升級(jí)透鏡生產(chǎn)廠商</p><p
