I-Corps: Ultrahigh Brightness LED Luminaire Development for Commercial Applications

在这个创新兵团项目中，拟议的努力是开发一种基于LED的产品，以取代荧光工业照明。无处不在的线性荧光T8灯泡产生超过3300流明，而最亮的LED替代灯泡产生不到2500流明。然而，客户对合适的基于LED的T8替代品的需求仍然很强烈，一个可以超过3300流明亮度障碍并提供良好光线质量的灯泡可以占领大部分市场。为了满足这一市场需求，该团队建议对基于无汞、低成本、现成组件的照明架构进行实验验证，该组件可以超过3300流明亮度，匹配或改进当前线性荧光灯的色温和显色指数，同时显示出空间均匀的发射图案。该团队提出的照明架构实现了基于LED的插入式线性荧光替代品，与典型的白色LED技术相比，在整个可见光谱范围内具有更高的功率转换效率，同时提供更美观的光线质量。重要的是，建议的设计利用了市场上可获得的、高效的和高度可调的发光染料，使无与伦比的光谱工程和适应众多专业市场(如水培、博物馆等)的能力，同时允许组件/供应流完全独立于稀土元素价格和可获得性的波动。

The proposed effort in this Innovation-Corps project develops a LED-based product to replace fluorescent industrial lighting. The ubiquitous linear fluorescent T8 light bulb generates over 3300 lumens, while the brightest LED-based replacement generates less than 2500 lumens. However, customer desire for an adequate LED-based T8 replacement remains strong, and a bulb that can exceed the 3300 lumens brightness barrier and offer good light quality can capture much of the market. To address this market demand, the team proposes to experimentally validate a lighting architecture based on mercury-free, low-cost, off-the-shelf components that can exceed 3300 lumens brightness, match or improve upon the color temperature and color rendering index of current linear fluorescent lamps, while exhibiting a spatially uniform emission pattern. The team's proposed lighting architecture enables a LED-based, drop-in linear fluorescent replacement with greater power conversion efficiency across the entire visible spectrum compared to typical white LED technologies, while providing a more eye-pleasing light quality. Importantly, the proposed design utilizes commercially-available, highly efficient, and highly tunable luminescent dyes that enable unrivaled spectral engineering and adaptation for numerous specialized markets (e.g. hydroponics, museums, etc.), while allowing the component / supply stream to become completely independent from the fluctuations in the price and availability of rare earth elements.
