Description

一种UVB太阳光补钙荧光灯的制备方法 技术领域：
本发明属于医疗照明技术领域，涉及一种UVB太阳光补钙荧光灯的制作方法，可用于畜牧业养殖补钙。
背景技术：
维生素D3是动物体内钙的新陈代谢的必需品，骨骼的强健和生长都离不开钙质。如果动物体内缺乏钙质，就容易引起骨骼新陈代谢方面的疾病。维生素D3还能够强化海龟和乌龟的龟壳。
尽管动物能够通过摄入食物而获得维生素D3，但是研究表明，通过饮食结构获得的D3不能够代替利用日光经由皮肤合成的维生素D3，甚至是给它们体内注射补充这种维生素也无法替代。
大多数动物需要靠皮肤合成健康生长所必须的维生素D3。因此，他们需要处于特殊波段的紫外线(被称为UVB中波紫外线)环境中。补钙灯就能够发射这种特殊波长的紫外光线
但是常规补钙灯的光谱在UVB波段还会出现一定的UVC能量输出，这个是会导致红眼病，长时间照射还会出现皮肤癌的风险。
发明内容
目前市场上面的UVB荧光粉是宽波荧光粉，半宽度很大，因此起始波段有UVC光谱，所以灯管含有UVC能量输出，UVC辐照会有红眼病，皮肤癌的风险。而且现有的UVB荧光粉强度很低，生产出的荧光灯UVB强度不高，不能满度一定高度下的UVB含量数值；另外， 光谱只是单纯有UVB，可见光光谱显色指数(RA)很低，单纯的是间断式光谱，不能象太阳光光谱一样完全光谱全覆盖。
本发明的目的是克服上述不足之处，提供一种UVB太阳光补钙荧光灯的制作方法。

(3)：灼烧产物经过破碎处理后过200-250目筛，中心粒径控制在5μm～10μm，接着用浓度为0.1％的硝酸溶液进行酸洗处理，酸洗过筛后的产品直至中性，然后抽滤、80-100℃烘干再过100-200目筛。
(4)：再次将过筛产品装入刚玉坩埚中，在氮氢(含5％-10％体积氢的氮气)混合气氛中灼烧2-4小时，灼烧温度控制在1450℃，最后的灼烧产品经过处理过筛即为成品，所得的发光物质粉体颜色为白色。
所述的可见光全光谱荧光粉组成为:根据化学组分式：(Sr1-x-yMgy)m(PO4)n:Snx，计算工艺原料配比，其中，0<x<0.5，0<y<0.5，3<m<4，2<n<3。优选可见光全光谱荧光粉 为磷酸锶镁铕。可见光全光谱荧光粉紫外光谱分析仪检测主峰620-630nm，颗粒大小为2-12um。

实施例2
一种UVB太阳光补钙荧光灯的制备方法，该方法包括常规的弯管、涂粉、烤管、封口、桥接、排气和老练步骤，在涂粉步骤中加入由高强度UVB荧光粉和可见光全光谱荧光粉组成的原料，其中，原料中，高强度UVB荧光粉为铝酸锶铈，占40wt％，可见光全光谱荧光粉为磷酸锶镁铕，占60wt％。
日光中的紫外线是人机体产生维生素D3的唯一来源，人体皮肤中的脱氢胆固醇经日光中紫外线照射后可转变为维生素D3。当维生素D3缺乏时，血钙、血磷下降，致骨骼钙化过程发生障碍，加速骨质的丢失和骨折率，因此缺乏室外活动者，接触阳光少，易得此类病。本发明解决缺维生素D3的人们在室内即可补充因自然阳光照射不足产生的缺陷。
试验例
明显缺钙患者30人，年龄30-60岁，在室内每天照射2小时本发明实施例光源，连续照射一个星期，通过医院骨密度检测后，人体的骨密度提高均在5-10％，且无不良反应，说明补钙疗效好，而且使用方便、安全。
