This Small Business Innovation Research (SBIR) Phase II project will result in solid-state high power UV LED based lamps for use in water/air/food sterilization/purification, bio-aerosol detection, bio-medical instrumentation, and laboratory measurement systems. Currently there are 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. High power deep UV LEDs require packaging designed to dissipate several watts of power, be stable under UV illumination, reflect UV light, and enhance UV extraction. The team proposes to develop manufacturing innovations in the packaging of high power UV LEDs to extend the range of applications that UV LEDs are suitable for including high power package/LED design, and the manufacturing processes required to fabricate these packages. Deep UV LED based lamps with output powers ranging from 50-100 mW are expected from this developmental effort. If successful these Deep UV LED-based lamps will penetrate existing markets using UV radiation sources as the efficiency of the devices increases, as well as creating new markets previously unattainable due to the inherent limitations of current UV sources. The merits of UV radiation for sterilization/purification applications are beginning to be widely publicized. Several of the primary markets are: 1) Sterilization/Purification for Water, Air, and Food Preparation/Storage, 2) UV Spectroscopic Laboratory Analysis Equipment, 3) Bio-medical instrumentation, and 4) Biological weapons detection using UV fluorescence. This expertise will expand the technology base of the U.S. semiconductor manufacturing sector. In addition, low power point-of-use purification systems enabled by this technology will meet a crucial humanitarian need.

这个小企业创新研究（SBIR）二期项目将产生固态高功率紫外LED灯，用于水/空气/食品灭菌/净化，生物气溶胶检测，生物医学仪器和实验室测量系统。目前还没有便携式、坚固耐用、长寿命、无毒的紫外线辐射源，无法整合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、中压和汞合金灯。这些高压灯是大的，无方向性的，臭氧产生的辐射源与径向发射的管源。由于灯的几何约束，这限制了净化系统的设计灵活性。高功率深紫外led要求封装设计为耗散几瓦的功率，在紫外线照射下稳定，反射紫外线，并增强紫外线提取。该团队建议开发高功率UV LED封装的制造创新，以扩展UV LED适用的应用范围，包括高功率封装/LED设计，以及制造这些封装所需的制造工艺。基于深紫外LED灯的输出功率范围为50-100兆瓦。如果获得成功，这些基于深紫外led的灯将随着设备效率的提高而进入使用紫外辐射源的现有市场，并创造由于当前紫外光源固有限制而无法达到的新市场。紫外线辐射用于灭菌/净化应用的优点开始被广泛宣传。几个主要市场是：1)水、空气和食品制备/储存的灭菌/净化，2)紫外光谱实验室分析设备，3)生物医学仪器，以及4)使用紫外荧光的生物武器检测。这将扩大美国半导体制造业的技术基础。此外，由该技术实现的低功耗使用点净化系统将满足关键的人道主义需求。
