Description

太阳光型光合转光玻璃平面光源
技术领域
本发明属于光功能玻璃技术领域， 更具体地说， 它涉及一种太阳光型光合 转光玻璃组件平面光源，在太阳光照射下能够发射特征波长为 660纳米的红光。 背景技术
植物光合作用需要的光照波长通常包括 400纳米至 500纳米的蓝光和 620纳 米至 680纳米的红光以及 720纳米至 740 纳米的远红光， 对植物的趋光性、 光合 作用和光形态发生作用。 具有上述波段对应的红光和蓝光同步辐射称为光合有 效辐射， 这种特种光中不含有波长在 280纳米至 320纳米的紫外光， 可防止对植 物色素的伤害。 同时具有特征波长为 660纳米的红光和 450纳米蓝光的光源对获 得高的光合量子产率具有重要作用，其中波长为 660纳米的宽谱带红光发射尤为 重要。 具有光合有效辐射的玻璃称为光合转光玻璃， 或者称为光合玻璃， 光合 玻璃的形式有光合转光中空玻璃组件和光合转光体玻璃两大类型。
实现植物生长光合作用所需要的具有特征波长为 660纳米红光的光合有效 光谱的光源， 有太阳光、 人工光以及混合光， 只依靠太阳光辐照就能获得特征 波长为 660纳米红光发射的光源称为太阳光型光源。在太阳光中， 太阳电磁辐射 中 99. 9%的能量集中在红外区、 可见光区和紫外区， 太阳辐射主要集中在波长 为 400纳米至 760纳米的可见光部分， 占太阳辐射总能量的约 50%。在可见光的蓝 紫光和绿光波段中， 包括 577〜492纳米的绿光， 492〜455纳米的蓝靛色和 455〜 390纳米的蓝紫光， 这些蓝紫光和绿光的能量并不被植物所吸收， 具有特征波长 为 660纳米的红光光源一直很稀缺， 需要研发高效率的转光材料和器件光源， 把 太阳光中的蓝紫光和绿光转成上述植物光合作用所需要的 660纳米红光。 在已经研发的转光材料中， 主要是掺有稀土的硫化钙发光材料及其转光塑 料薄膜产品， 存在的不足有： 转光产品暴露在湿热空气中， 结晶度和转光效率 不高， 化学不稳定， 容易潮解， 容易劣化； 废弃后也不容易降解， 形成二次污 染； 把微米发光颗粒分散在塑料中也会困难； 混入的稀土元素也不容易回收； 这种转光薄膜的机械强度很低， 容易破损。
采用超白压花玻璃实现光合有效发射可以减小光散射， 把发射红蓝光的材 料和光源放置于中空玻璃组件内， 可以隔离发光源受环境的影响， 通过玻璃表 面的微米纳米结构可以解决出射光的反射以及导出效率问题。
