这个小企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是通过使用激光技术和材料设计创造一种节能、高色彩质量和成本效益的传统光源替代品，在大功率照明市场上节省能源和电力。这种创新的商业化可能会导致下一代节能光源的出现，超越当前照明技术的限制，并在大功率市场上大幅增加节能光源的可用性和吸收率。由于照明是商业和工业市场用电的主要来源，这反过来将有助于减少全球能源消耗，并有助于保护我们的环境。从这些研究中获得的知识将为未来的材料研究提供信息，以开发具有最佳性能的坚固材料，以推进固态照明，以及其他能源相关技术，包括太阳能技术。这个小型企业创新研究（SBIR）一期项目旨在通过探索激光激发的荧光粉发射，推进固态照明领域的研究，朝着超高效和智能照明的目标迈进。特别是，提议的创新侧重于大功率照明市场的节能，由于LED下垂，大功率发光二极管（LED）技术无法达到低功率LED技术所达到的能效。激光技术的使用可以同时克服下垂的负面影响，同时也利用激光的定向特性来创建一个聚焦的光源，可以更好地控制和传递到照明区域，损失更少，整体效率更高。该项目将解决使用光学建模的设备设计，以最大限度地提高照明性能指标，并将开发材料系统，以减轻使用强光源（如激光或高功率LED）时引入的热效应，这些光源会损坏和降解设备内的材料。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to deliver energy and electricity savings in the high-power lighting market, by creating an energy-efficient, high color-quality, and cost effective alternative to conventional light sources using laser technology and materials design. Commercialization of this innovation could lead to the next generation of energy-efficient light sources, surpassing the limitations of current lighting technologies and drastically increasing the availability and uptake of energy-efficient light sources in the high-power market. As lighting is a major source of electricity use in the commercial and industrial markets, this would in turn aid in reducing global energy consumption and help to preserve our environment. The intellectual knowledge gained from these studies will inform future materials research in developing robust materials with optimal properties to advance solid-state lighting, as well as other energy related technologies including solar energy technologies. This Small Business Innovation Research (SBIR) Phase I project aims to advance research in the field of solid-state lighting towards the goal of ultra-efficient and smart lighting by exploring laser-stimulated phosphor emission. In particular, the proposed innovation focuses on energy savings in the high-power lighting market, where high-power light emitting diode (LED) technology does not attain the energy efficiency seen in low-power LED technology, due to LED droop. The use of laser technology can simultaneously overcome the negative effects of droop while also leveraging the directional nature of a laser to create a focused light source that can be better controlled and delivered to the illumination area with less losses and higher overall efficiency. This project will address device designs using optical modeling to maximize lighting performance metrics and will develop materials systems to mitigate the thermal effects introduced when using an intense light source such as a laser or high-power LED, which can damage and degrade materials within the device.
