The DOE Lighting R&D Program is driving innovative lighting research and development (R&D) that will redefine lighting – and related energy savings – for the next century. Solid-state lighting (SSL), particularly light-emitting diode (LED) based SSL, is on course to become the dominant lighting technology across all lighting applications.
The luminous efficacy of SSL has surpassed previous lighting technologies and still has significant room to improve. Moreover, the LED technology platform offers the opportunity to:
- Advance beyond legacy form factors, which embody limitations of previous lighting technologies
- Move past the legacy functionality of providing basic illumination, to explore new functionality with potential to improve building occupant well-being and productivity
- Enable energy savings beyond improved source efficiency to encompass more precise delivery of more suitable light at the appropriate time
SHAPING THE R&D AGENDA
DOE Lighting R&D Program priorities are guided by the Lighting R&D Opportunities document, updated annually in collaboration with the U.S. lighting research community. Input is collected through ongoing stakeholder engagement and annual workshops that bring together America's top scientists and lighting experts to focus on lighting R&D advances. These exchanges inform not only DOE-sponsored R&D, but also research agendas in academia and industry.
All DOE SSL funding opportunity announcements (FOAs) and project selections align with the priorities and targets detailed in the Lighting R&D Opportunities document. DOE lighting R&D projects are competitively selected and cost-shared projects that explore complex science challenges that stand in the way of further improvements in efficacy and performance. Solicitations for R&D funding are issued annually. R&D partners and projects are selected based on factors such as energy savings potential, likelihood of success, and alignment with the Lighting R&D Opportunities document.

SCIENTIFIC MEASUREMENT AND VALIDATION TESTING
DOE funds ongoing research conducted by the National Institute of Standards and Technology (NIST) to provide lighting measurement science, testing and standards support, and source characterization. In addition, testing conducted by RTI International augments our understanding of LED and OLED reliability, and an OLED component testing collaborative provides rapid feedback to component makers regarding best performing components and approaches.
