一种平板荧光灯的制造方法 【技术领域】
本发明涉及荧光灯及其制造方法，尤其是涉及一种平板荧光灯的制造方法。
【背景技术】
气体放电灯都是管状结构，目前，气体放电灯的制造方法包括形成放电容器，该放电容器是一根一端封闭的玻璃管或陶瓷管，玻璃管或陶瓷管有一开口端。通过真空装置直接对放电容器开口进行抽真空或将放电容器置于密封的工艺容器中再对该密封容器进行抽真空同时也对该放电容器玻璃或陶瓷管进行了抽真空形成真空环境，即使得该放电容器玻璃管或陶瓷管满足真空要求；充放电介质；密封该放电容器玻璃管或陶瓷管的开口孔形成真空放电灯管。
平板荧光灯属于气体放电灯，平板荧光灯的结构是由两块玻璃板做成，两块玻璃板之间设置有放电通道、放电通道壁上设置有荧光粉发光材料，放电通道内充有放电气体介质及汞，放电通道两端设置有电极。一种典型的平板荧光灯是：外电极平板荧光灯（英文简称EEFL），被研发用于液晶装置的背光光源。作为普通照明产品的研发正处于试验阶段，用于背光源和普通照明的技术区别是：普通照明要求光效更高、单位面积的发光强度高。外电极平板荧光灯与普通荧光灯比，具有寿命长达30000小时以上，普通荧光灯一般寿命为10000小时；可实现高光效率线性调光，普通荧光灯调光效果差，调光效率低；可实现无数次的开关，试验的数字高达5000000次而电极无损耗，普通荧光灯一般的开关次数为10000次；与管状荧光灯比系统照明效率高，由于扁平结构，特别适合天花板灯。因此具有LED的所有性能，且光的颜色比LED更好。平板荧光灯一般可以做成单面发光和双面发光光源。
