作为世界上照明行业最具经验的光学玻璃元件设计者和制造商之一，Auer Lighting 傲尔照明高度推荐玻璃应用于LED。这是由于玻璃具有极佳耐候性，透明度以及能够承受温度远高于300℃ 而性能不变的能力。尤其是随着 LED 功率的上升，产生更多热量，这一点变得越来越重要。 由塑料材料制成的光学元件只能在低得多的温度下保持稳定，已经限制了高功率照明系统的潜在性能。玻璃的优势使得客户能使用更强大的光源，使LED照明达到全新的亮度水平。

玻璃是LED持久耐用的完美伴侣，因为其耐用性以及多样的形状和功能。 而温度对于玻璃来说是没有问题的。 它可以很容易地镀膜（以提高初始性能）和清洁（保持最初的性能）。
从成本方面来说，玻璃光学元件价格可以非常具有竞争力，特别是对于专业和/或高端光学元件。现有的塑料光学元件达不到这样要求。
为什么到目前为止玻璃在LED排在世界第二位是不容易理解的。 但它显示出如此多的有价值和有趣的功能，以至于再也无法忽略它了
