1、光器，這是調(diào)光技術(shù)很多年沒有發(fā)展的主要原因；LED又可以調(diào)光了，并且無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合，LED燈有優(yōu)勢。 </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 /> </p><p> 二、結(jié)合工藝落實(shí) </p> <p> <br /> </p> <p> 激光透鏡對于工藝的要求很高，只有建立在好的工藝基礎(chǔ)上才能有效的實(shí)現(xiàn)作用的發(fā)揮，好的激光透鏡都會采用精湛的雙面鍍膜工藝完成，減少應(yīng)反射造成的損耗，降低飛濺物的危害影響，與其高精度的加工實(shí)現(xiàn)，通過運(yùn)用優(yōu)良的基片，完善切片、拋光、打磨等細(xì)加工工藝，從而發(fā)揮出更好的耐高溫和抗激光性，所以要想客觀的衡量激光透鏡從工藝的要點(diǎn)入手必不可少，只有確保工藝的現(xiàn)代化高標(biāo)準(zhǔn)完善才能確保使用價(jià)值的完成。 </p> <p> <br /> </p> <p> 當(dāng)然在具體的激光透鏡衡量過程中不可或缺的還是要了解品牌的相關(guān)內(nèi)容，只有建立在品牌的基礎(chǔ)上深入綜合性價(jià)比的比較才能更進(jìn)一步的完成針對性更強(qiáng)的衡量落實(shí)，才能在根本上更好的為后續(xù)的激光透鏡使用完成提供后盾依托，才能真正為采購合作的實(shí)現(xiàn)奠定優(yōu)化的系統(tǒng)保障實(shí)現(xiàn)。

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)的改良工藝來說，只能通過鍍膜或鋼化處理來提升玻璃的不易碎特性，雖然經(jīng)過這些處理，玻璃透鏡的透光率會有所降低，但依然會遠(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。
