Description

一种 用于LED灯具的透镜 技术领域
本实用新型涉及一种透镜，特别涉及 一种用于LED灯具的透镜。
背景技术
LED 作为定向光源，在定向照明领域节能优势非常明显，得到了广泛的应用。定向照明主要要求显色性较高的暖色光，对 LED 来说，暖色光显色性都能达到 80 以上，但其光效却比冷色光低 20% － 30% ，现在冷白光量产水平已达到 130lm/W ，但暖色光最高只有 100lm/W ，价格甚至比高亮的冷色光更贵。
暖色 LED 现在主要是将黄色（或黄色加红色）荧光粉涂布在蓝光晶片上，通过蓝光激发黄色（或黄色加红色）荧光粉得到暖白光。一方面，这样暖色的 LED 的光效不高（比冷色光低 20% － 30% ）；另一方面，这样 LED 的封装均存在专利壁垒。
 技术解决方案
本实用新型克服了上述现有技术中的不足，提供了 一种用于LED灯具的透镜，该透镜是在 LED 光源容置空间的入射底面、入射侧面上 涂布稀土荧光粉或是量子点荧光粉，当将蓝光LED放置在透镜的 LED 光源容置空间内 点亮时，便可以得到各种白光 。
本实用新型的技术方案是这样实现的：
一种用于LED灯具的透镜 ，包括透镜本体，在透镜本体内设有 LED 光源容置空间，该 LED 光源容置空间具有使光线进入到透镜本体的入射侧面、入射底面，在入射侧面和入射底面上均涂覆有稀土荧光粉涂层。
一种用于LED灯具的透镜 ，包括透镜本体，在透镜本体内设有 LED 光源容置空间，该 LED 光源容置空间具有使光线进入到透镜本体的入射侧面、入射底面，在入射侧面和入射底面上均涂覆有量子点荧光粉涂层。
 有益效果
本实用新型是将单颗或多颗组合透镜的 LED 光源容置空间的入射底面、入射侧面上涂布稀土荧光粉或量子点荧光粉，将蓝光 LED 放置在 LED 光源容置空间内，便可以得到各种白光。由于蓝光 LED 不存在专利的问题，所以即使使用国产的 LED ，整个白光 LED 灯也不会有白光专利的风险。并且，如果使用量子点（ Quantum Dot ）荧光粉，也可以实现将高效率的白光转化成高光效暖白光 。
附图说明
图 1 为本实用新型实施例1中透镜的结构示意图 ；
图 2 为图 1 的剖视图；
图 3 为本实用新型实施例 2 中透镜的剖视图。
