</p> <p> <br /> </p><p> 應(yīng)用分類 </p> <p> 一次透鏡 </p> <p> a. 一次透鏡是直接封裝（或粘合）在LED芯片支架上，與LED成為一個(gè)整體。 </p> <p> b. 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 /> 漢雷光電品牌透鏡，為您提供專業(yè)咨詢！</p><div
