2 Why Standards and Tests Just for SSL (LED)? Lighting Industry relies on effective Standards Uniformity among products Performance output, life, color Application format, compatibility Customer satisfaction Confidence in manufacturer s data Comparable characterization Understandable characterization! LEDs do not function like other light sources Heat Build-up issue! Directionality 5/7/2009 1

3 Misleading Data..to..Outright Exaggeration! Produces no heat! Brighter than a fluorescent light Lasts Forever! Uses almost no energy! Replaces a 60 Watt incandescent Misleading claims hurt ANY technology s success and wide-spread application. A repeat of the same exaggeration issues with CFL must be avoided! 5/7/2009 2

4 The players in Standards Development Many hands (can) make light work but committee process can be slow or lack drivers The need is known but committees don t typically have milestones or deadlines for new efforts 5/7/2009 3

5 U.S. Department of Energy (DOE) Mandate The DOE is directed by U.S. government policy (EPACT 2005, Section 912) to: support research, development, demonstration, and commercial application activities related to advanced solid-state lighting technologies based on white light emitting diodes. or We re from the government: we re here to help! 5/7/2009 4

6 DOE SSL Industry Support Strategy Support product commercialization and user awareness to promote the market and avoid problems before products reach the market Accelerate SSL Standards and Test Methods development to make critical procedures available early Work closely with industry Standards organizations..industry should take the lead 5/7/2009 5

Commercialization Support: ENERGY STAR for SSL ENERGY STAR for SSL - the initial DOE support task Two-phase approach Category A: Specific Interim applications Category

8 Commercialization Support: ENERGY STAR for SSL ENERGY STAR for SSL - the initial DOE support task Two-phase approach Category A: Specific Interim applications Category B: Efficacy based performance Criteria addresses: Application performance Color quality Luminaire efficacy Effective for manufacturers on September 30, /7/2009 7

9 ENERGY STAR Needs: What s DOE to do? Initial needs identified early for success of the program: Luminous output and electrical measurement Lifetime metrics Color characterization Terminology More needs as the program has developed: Photometric distribution Sampling and measurement repeatability Durability DOE can and will develop standards where none exist but smart enough to realize importance of industry development and supportive of the existing processes 5/7/2009 8

10 DOE Hosted First Standards Workshop March 1, 2006 Gathering of major standards and test methods organizations Review of the industry need for LED standards and methods Review of organization development processes and impacting timelines 5/7/2009 9

11 Major Workshop Results. Standards/Test Methods Identified for Industry and Energy Star: Photometric/Electrical measurement Lifetime lumen depreciation Chromaticity Definitions/Terms Major Working groups formed Luminous Flux, Power, Color/Chromaticity, Definitions Plus: Calibration, UL conditions of Acceptability, interchangeability Standards development timeline Typically measured in years but interest in moving faster Standards groups chose the DOE Energy Star timeline as a development goal 5/7/

12 Working Group Activity 2006 to Now ANSI/IESNA/NEMA meetings Report working group progress Address combined issues Focus on industry needs Identify support needs to DOE ANSI/IESNA/NEMA working group conference calls Continue specific group development Consider manufacturer issues and market needs NEMA, DOE, and manufacturer hosted calls Additional DOE hosted workshops and roundtables Workshops combined with CALiPER testing program October 2006, November 2007, March 2008 (designer roundtable), and March /7/

Key DOE SSL Programs to Date Related to SSL Standards Product performance certification (ENERGY STAR) Technology Demonstrations (GATEWAY) Luminaire

14 Key DOE SSL Programs to Date Related to SSL Standards Product performance certification (ENERGY STAR) Technology Demonstrations (GATEWAY) Luminaire Competitions (LFT, NGL) Independent commercial product testing (CALiPER) Technical information network (Fact Sheets) Lighting Facts (comparable labeling) 5/7/

The GATEWAY Program (Demonstrations) Demonstrate new SSL products in real world, general

cost-effective for the user Provide consistent demonstration process for

go decision) Conduct repeatable in-situ measurements, pre- and post-installation Get user

15 The GATEWAY Program (Demonstrations) Demonstrate new SSL products in real world, general illumination applications that: Save energy Match or improve illumination Are cost-effective for the user Provide consistent demonstration process for repeatable/comparable data Receive or initiate projects Assess project suitability (go/no go decision) Conduct repeatable in-situ measurements, pre- and post-installation Get user feedback on illumination quality Conduct economic/performance evaluations Document results, share widely 5/7/

16 Luminaire Competitions: LFT, NGL Objectives: Next Generation Luminaires Increase market visibility and availability of quality SSL products Educate market of technical potential of well designed products Encourage product innovation Promote excellence 5/7/

17 DOE CALiPER Program (Commercially Available LED Product Evaluation and Reporting) Provide objective, high quality performance information Know performance of market available products To support R & D planning To support ENERGY STAR Inform industry test procedures and standards development Discourage low quality products Reduce SSL market risk due to buyer dissatisfaction from products that do not perform as claimed 5/7/

18 Technology Information: Fact Sheets Written for technology users Lighting designers Architects Builders Updated as technology changes Subjects: Thermal Management Lifetime Color Quality Efficiency Applications: recessed downlights, etc. 5/7/
