</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> 第二種透鏡側(cè)壁面采用自由曲面設(shè)計(jì)，近光面復(fù)眼珠面，出光角度250-600可調(diào)，一般使用PC材質(zhì)，江蘇國(guó)產(chǎn)透鏡批發(fā)廠，可用于比較大出光面直徑14mm的COB光源射燈，其光學(xué)有效透過(guò)率比較大可達(dá)到95%。 </p> <p> <br />

style="text-indent:25px">4．我們選擇將光源放于透鏡焦點(diǎn)的內(nèi)側(cè)，光源離透鏡越遠(yuǎn)，透鏡收集到的光源光通量越少，因而透鏡系統(tǒng)的效率越低，根據(jù)單凸透鏡的計(jì)算公式：r=（nL－1）f。其中r—凸面曲率半徑，nL—透鏡材料折射率，f—透鏡焦距在選定透鏡材料的情況下，焦距越大，曲率半徑越大。在同樣透鏡孔徑Φ的條件下，曲率半徑越大，透鏡越薄。而透鏡越厚，像差會(huì)越明顯，從而影響使用效果。因此，盡可能選擇焦距較大的透鏡。同時(shí)，焦距的增大，光學(xué)系統(tǒng)尺寸的增加，因此，透鏡的焦距也不可以一味追求比較大。由于透鏡厚度不是很大，因此沒(méi)有采用菲涅耳透鏡，避免增加加工的繁瑣性和成本。山東超亮透鏡代理商品牌透鏡采購(gòu)，歡迎致電漢雷光電！</p><div

當(dāng)選擇改裝車燈，但是很多人不知道LED雙光透鏡和激光大燈的區(qū)別。近幾年隨著汽車照明技術(shù)的高速發(fā)展，從之前的鹵素?zé)舻诫瘹鉄?，再到現(xiàn)在的LED大燈，激光大燈等，當(dāng)然車燈改裝市場(chǎng)也不例外，從之前的氙氣燈透鏡到LED透鏡再到激光大燈。下面我們就來(lái)給大家說(shuō)一下LED雙光透鏡與激光LED雙光透鏡大燈的區(qū)別。 </p> <p> <br /> </p><p> 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> PC透鏡 </p> <p> a. 光學(xué)級(jí)料Polycarbonate（簡(jiǎn)稱PC）聚碳酸酯。 </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）；透光率稍低（3mm厚度時(shí)穿透率89%左右）；缺點(diǎn)：溫度不能超過(guò)110°（熱變形溫度135°）。 </p> <p> 玻璃透鏡 </p> <p> 光學(xué)玻璃材料，優(yōu)點(diǎn)：豐富的光學(xué)參數(shù)特性（可選擇），具有透光率高（3mm厚度時(shí)穿透率97%）、耐溫高等特點(diǎn)；缺點(diǎn)：體積大質(zhì)量重、形狀單一、易碎、批量生產(chǎn)不易實(shí)現(xiàn)、生產(chǎn)效率低、成本高等。前此類生產(chǎn)設(shè)備的價(jià)格高昂，短期內(nèi)很難普及。此外玻璃較PMMA、PC料易碎的缺點(diǎn)，還需要更多的研究與探索，可以實(shí)現(xiàn)的改良工藝來(lái)說(shuō)，只能通過(guò)鍍膜或鋼化處理來(lái)提升玻璃的不易碎特性，雖然經(jīng)過(guò)這些處理，玻璃透鏡的透光率會(huì)有所降低，但依然會(huì)遠(yuǎn)遠(yuǎn)大于普通光學(xué)塑料透鏡的透光效果。所以玻璃透鏡的前景將更為廣闊。

.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 /> led透鏡具有亮度高、顏色種類豐富、低功耗、壽命長(zhǎng)的特點(diǎn)！江蘇國(guó)產(chǎn)透鏡批發(fā)廠</p><p
