This Small Business Innovation Research Phase I research project aims to develop high power UV LED based lamps for use in water/air/food sterilization/purification, bio-aerosol detection, and laboratory measurement systems. There are currently no portable, rugged, long-lifetime, non-toxic sources of ultraviolet radiation for integration into increasingly important UV water and air purification (particularly residential), bio-aerosol detection, and food sterilization systems. The predominant sources of UV radiation are low-pressure, medium-pressure and amalgam Hg based lamps. These high voltage lamps are large, non-directional, ozone-producing sources of radiation with radial emission from a tube source. This restricts the design flexibility of purification systems because of the geometrical constraints imposed by the lamp. More important than system design restrictions, however, is that these lamps produce dangerous ozone gas and each lamp contains approximately 60, 120 and 300 mg of Hg for low pressure, amalgam, and high pressure lamps, respectively. Deep UV LEDs with emission wavelengths below 365 nm require new UV compatible reflective coatings, UV resistant encapsulation with proper refractive index matching and new UV-transparent optics designs. The company proposes to develop manufacturing innovations in the packaging of high power UV LEDs to extend the range of applications for which UV LEDs are suitable.If successful this solution will service the following markets: i. Sterilization/Purification for Water, Air, and Food Preparation/Storage. ii. UV Spectroscopy and Lab Equipment Manufacturing for Biological, and Optical Research and Development. iii. Biological weapons detection using UV fluorescence.

该小型企业创新研究第一阶段研究项目旨在开发用于水/空气/食品灭菌/净化，生物气溶胶检测和实验室测量系统的高功率UV LED灯。目前没有便携式、坚固耐用、寿命长、无毒的紫外线辐射源可用于集成到日益重要的紫外线水和空气净化（特别是住宅）、生物气溶胶检测和食品灭菌系统中。紫外线辐射的主要来源是低压、中压和汞齐汞灯。这些高压灯是大的、非定向的、产生臭氧的辐射源，具有来自管源的径向发射。由于灯所施加的几何约束，这限制了净化系统的设计灵活性。然而，比系统设计限制更重要的是，这些灯会产生危险的臭氧气体，低压灯、汞齐灯和高压灯的每盏灯分别含有约60、120和300毫克的汞。发射波长低于365 nm的深紫外LED需要新的紫外兼容反射涂层、具有适当折射率匹配的抗紫外封装和新的紫外透明光学设计。该公司建议开发高功率紫外线LED封装的制造创新，以扩大紫外线LED适用的应用范围。如果成功，该解决方案将服务于以下市场：i.水、空气和食品制备/储存的灭菌/净化。二.紫外光谱和实验室设备制造的生物，光学研究和开发。三.利用紫外荧光探测生物武器。
