隨著現(xiàn)代化工藝的不斷提升，口碑好的激光透鏡在生產(chǎn)工藝及材料的融入上有了質(zhì)的提升，從而在根本上有效的促進(jìn)了激光透鏡使用的品質(zhì)展現(xiàn)，使其的使用模塊以及使用寬度都有了系統(tǒng)的提升，那么要想更為精細(xì)的了解專業(yè)的激光透鏡品質(zhì)是否可靠可以深入看哪些內(nèi)容？ </p> <p> <br /> </p> <p> 一、材質(zhì)的考量 </p> <p> <br /> </p> <p> 受歡迎的激光透鏡必然會(huì)在材質(zhì)的落實(shí)上非常謹(jǐn)慎，通過(guò)好的先進(jìn)進(jìn)口的質(zhì)量晶體確保激光透鏡功能的進(jìn)一步實(shí)現(xiàn)，嚴(yán)格原材料引進(jìn)的每一個(gè)步驟，進(jìn)而確保材質(zhì)呈現(xiàn)出更***的光學(xué)、熱學(xué)、機(jī)械性能，因而在落實(shí)激光透鏡品質(zhì)考量的過(guò)程中一定要優(yōu)先主要從使用原材料的內(nèi)容導(dǎo)入實(shí)施，只有建立在優(yōu)化原材料基礎(chǔ)上才能在根本上實(shí)現(xiàn)激光透鏡使用功能的優(yōu)化實(shí)現(xiàn)。

LED透鏡即與LED緊密聯(lián)系在一起能增強(qiáng)光的使用效率和發(fā)光效率，可以根據(jù)不同的效果來(lái)使用不同的透鏡改變LED的光場(chǎng)分布的光學(xué)系統(tǒng)。其他類型的透鏡如：用于照相機(jī)、望遠(yuǎn)鏡等的透鏡不屬于本文講解范圍，著重講解用于大功率LED的二次聚光透鏡。 </p> <p> 材料分類 </p> <p> 硅膠透鏡 </p> <p> a. 因?yàn)楣枘z耐溫高（也可以過(guò)回流焊），因此常用直接封裝LED發(fā)光器件。 </p> <p> b. 一般硅膠透鏡體積較小，直徑3-10mm。 </p> <p> PMMA透鏡 </p> <p> a. 光學(xué)級(jí)PMMA（聚甲基丙烯酸甲酯，俗稱：亞克力）。 </p> <p> b .塑膠類材料，優(yōu)點(diǎn)：生產(chǎn)效率高（可以通過(guò)注塑、擠塑完成）；透光率高（3mm厚度時(shí)穿透率93%左右）；缺點(diǎn)：溫度不能超過(guò)80°（熱變形溫度92度）。 </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 /> LED大燈帶透鏡有什么好處？</p><div style="width:100%;text-align:

LED透鏡作為光學(xué)級(jí)的產(chǎn)品，對(duì)透光性、熱穩(wěn)定性、密度、折射率均勻性、折射率穩(wěn)定性、吸水性、混濁度、比較高長(zhǎng)期工作溫度等都有嚴(yán)格的要求。因此，必須根據(jù)實(shí)際選擇透鏡的材料。原則上選擇光學(xué)級(jí)PMMA，如有特殊的需求可選擇光學(xué)級(jí)PC。目前為日本三菱PMMA材料為比較好（VH001是經(jīng)常選擇的牌號(hào)），三菱公司在中國(guó)的分廠南通麗陽(yáng)就會(huì)稍遜一些； </p> <p> 2．必須配備萬(wàn)級(jí)甚至更高級(jí)別的無(wú)塵車間，作業(yè)人員必須著防靜電服裝、戴手指套、戴口罩等防靜電防塵措施，并且定期對(duì)車間做檢驗(yàn)與清理。 </p> <p> <br /> 漢雷光電提供專業(yè)透鏡咨詢！浙江升級(jí)透鏡生產(chǎn)廠商</p><p
