Partners: None
DOE Total Funding: $1,494,075
Project Term: April 1, 2019 – June 30, 2021
Funding Type: SSL R&D Funding Opportunity Announcement (FOA) (DE-FOA-0001823)
Project Objective
This project will develop a platform of high-luminance LEDs and LED light engines to increase efficacy and reduce energy consumption of directional lighting applications. The platform will be enabled by an integrated development effort with innovations in three key areas. First, the efficacy of high-luminance LEDs will be significantly increased by the development of epitaxy and device architectures optimized for high drive current density, breaking through the tradeoff in efficacy (lm/W) vs. emittance (lm/mm2) exhibited by state-of-the-art products. Second, a compact chip-scale package will be developed that will allow high packing density and thus high overall luminance in multi-emitter arrays. Third, phosphor technology will be developed to enable CCT tuning functionality in multi-emitter arrays with optimized LED utilization, efficacy, color uniformity, and color quality across the CCT tuning range.
Project Impact
Directional indoor and outdoor applications make up a major portion of the total lighting energy consumption in the U.S, accounting for >40% of the energy savings potential of solid-state lighting. This project will accelerate the realization of these energy savings through both higher system efficacy and adoption due to new functionality, and thus will contribute significantly to achieving DOE’s SSL performance goals.
