To accelerate the development and implementation of needed standards for solid-state lighting products, DOE works closely with a network of standards-setting organizations and offers technical assistance and support.
Since 2006, DOE has facilitated ongoing dialogue with key standards development organizations to foster greater coordination and collaboration among related efforts. Technical support from DOE has been instrumental in the development of many standards that set the foundation for SSL product development and deployment, including:
- IES LM-79-2008, Approved Method for the Electrical and Photometric Testing of SSL Devices
- IES LM-80-2008, Approved Method for Measuring Lumen Depreciation of LED Light Sources
- IES TM-21-2011, Projecting Long Term Lumen Maintenance of LED Light Sources
In most cases, these standards reflect years of technical support and committee meetings to forge industry consensus.
In 2015, two standards expected to impact SSL product development were published:
- IES TM-30-2015, Method for Evaluating Light Source Color Rendition (see Frequently Asked Questions about TM-30 and color rendering)
- IEEE 1789-2015, Recommended Practices for Modulating Current in High-Brightness LEDs for Mitigating Health Risks to Viewers (learn more about Understanding Flicker)
In addition, DOE is supporting a number of efforts that are poised to release standards important to the future of SSL, including:
- ANSI C136, Roadway and Area Lighting Equipment
- ANSI C137, Lighting Systems
- CIE TC1-83, Visual Aspects of Time-Modulated Lighting Systems
- CIE JTC7, Discomfort Caused by Glare from Luminaires with a Non-Uniform Source Luminance
- CIE TC4-52, Lighting for Pedestrians: New Empirical Data
RELATED TECHNICAL ASSISTANCE AND ANALYSIS
DOE provides technical assistance and analysis for a wide range of standards-setting organizations and industry consortia working on critical issues such as LED flicker, glare, color rendering, reliability, and interoperability.
DOE technical contributions and stakeholder education efforts have been key to the development of numerous specifications, such as NEMA SSL 7A-2013, Phase Cut Dimming for Solid State Lighting: Basic Compatibility. In addition, DOE has long offered technical assistance and hosts conference calls to facilitate the ongoing work of the LED Systems Reliability Consortium (LSRC), which has developed and published several reports that deepen understanding of LED product performance and reliability. This group of industry experts continues to work collaboratively in an ongoing effort to develop an advanced luminaire reliability model for SSL manufacturers and end users, with a current focus on color shift and stability. DOE technical support also informs the work of ENERGY STAR® and California Title 20/24 efforts, as well as DLC Commercial Advanced Lighting Controls (CALC) program development.
With the advent of connected lighting, and the role interoperability is expected to play in expanding its reach and impact, DOE is exploring ways to support the efforts of industry consortia, including The TALQ Consortium, The Connected Lighting Alliance, and the AllSeen Alliance, among others.
