Abstract

To optimally address this HSL for Army expeditionary shelters, we propose two novel innovations: (1) a flat-panel Passively-Tracking Solar Concentrator, leveraging our existing Holographic Solar Concentrator technology, to achieve high (>400x) concentration ratios with an ultra-wide (>100°) acceptance angle, mitigating the need for mechanical tracking and efficiently gathering diffuse light in cloudy conditions, and (2) a novel, high-efficiency Luminary design, leveraging the advances in weight, cost, lifetime, durability and luminous efficiency of both modern LCD (laptop/TV) backlights and LED downlighting. The overall lighting system is much more compact (
