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.

在这个创新团队项目中，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替代品产生不到2500流明。然而，客户对基于LED的T8替代品的需求仍然强烈，并且可以超过3300流明亮度屏障并提供良好光质量的灯泡可以占据大部分市场。为了满足这一市场需求，该团队建议通过实验验证一种基于无汞、低成本、现成组件的照明架构，该组件可以超过3300流明亮度，匹配或改善当前线性荧光灯的色温和显色指数，同时表现出空间均匀的发射模式。与典型的白色LED技术相比，该团队提出的照明架构能够实现基于LED的插入式线性荧光灯替代品，在整个可见光谱范围内具有更高的功率转换效率，同时提供更悦目的光质量。重要的是，所提出的设计利用了市售的、高效的和高度可调的发光染料，其能够实现无与伦比的光谱工程和对许多专业市场（例如，水培、博物馆等）的适应，同时允许组分/供应流变得完全独立于稀土元素的价格和可获得性的波动。
