DOE Total Funding: $3,994,729
Cost Share: $4,626,422
Project Term: August 15, 2012 – September 30, 2015
Funding Opportunity: SSL Manufacturing R&D Funding Opportunity Announcement (FOA) (DE-FOA-0000561)
Project Objective
The objective of this project is to develop, characterize, and verify a high-throughput, precision hot test tool toward the target measurement of one MacAdam ellipse, the color coordinate consistency required to intersect the achromatic side-by-side white lighting application, the largest sector of the lighting market, currently unserved by low-cost solid-state lighting. The CIE coordinates and efficacy will be measured at precise customer luminaire packaged product operating conditions by producing and measuring, at the wafer level, the anticipated conditions over a wide range. The recipient proposes to provide this capability for a wide range of LED-phosphor products, including phosphors using both silicone and Lumiramic sintered ceramics as phosphor binders.
Project Impact
Current hot testing approaches only approximate actual use conditions and are very slow. By addressing these issues, the hot test tool will have an impact on the HBLED manufacturing process such that 2 quads of energy savings could be achieved at full market penetration. Nationwide, lighting buildings costs $58 billion a year and consumes about 22% of all electricity generated.
