一个高效率的氙准分子灯辐射在172 nm，与内部荧光粉涂层转移到UVC已被证明，显示了成本效益的替代UVC汞灯的可行性。如此设计的荧光灯可以高效率地制造成各种几何形状。与其他基于介质阻挡放电的氙受激准分子灯不同，这种新系统与现有的和提议的磷光体高度兼容，因为它在中等温度下在惰性气体环境中操作，并且仅受到172 nm的初级辐射。使用涂有UVC磷光体的灯，我们已经证明了具有40%能量转换效率和高功率密度的杀菌和固化灯的可行性。这些灯可快速切换，预期寿命长，并与调光器兼容。(C)2013 AIP Publishing LLC.
A high efficiency xenon excimer lamp radiating at 172 nm, with an internal phosphor coating shifting to UVC has been demonstrated, showing the feasibility of a cost effective alternative to UVC mercury lamps. Fluorescent lamps so designed can be fabricated in various geometries with high efficiency. Unlike other xenon excimer lamps based on dielectric barrier discharges this new system is highly compatible with existing and proposed phosphors as it operates in an inert gas environment at modest temperature and is subject only to 172 nm primary radiation. Using a lamp coated with a UVC phosphor we have demonstrated the feasibility of germicidal and curing lamps with 40% energy conversion efficiency and high power density. These lamps are rapidly switchable, have long projected lifetimes and are compatible with dimmers. (C) 2013 AIP Publishing LLC.
