One & Done Connection to DOEs SSL Work

' -

Lighting (TINSSL) increases awareness of SSLtechnology, performance, and appropriate

.

TINSSL members receive regular updates ontechnical progress of SSL technologies, upcomingmeetings and events that address market issues

related to SSL, and outreach materials developed for

target audiences.

LM-79 Scope

LED-based SSL products with control electronics andheat sinks incor orated, devices that re uire onl AC

mains power or a DC voltage power supply to operate.

LM-79 Scope

Addresses test conditions and measurement methods Typically via integrating sphere Derived: CCT, D , CRI

New: CQS



8/29

LM-79 Scope

Addresses test conditions and measurement methods Only via goniophotometer Derived: zonal lumens, BUG



9/29

LM-79 Scope

Addresses test conditions and measurement methods, ,

Derived: efficacy (lm/W)o Total luminous out ut (lumens)

Interpolation required for gonio data

LM-79 Scope

Does not standardize report format or content Can be just spatial (BUG) or just spectral (CCT) Manufacturers often unaware data is incom lete

o Reports generally dont indicate make/model info for LEDs integrated into lamp or luminaire

ou e use u n eva uat ng su m tte -80, uttest lab probably not able to determine

-wouldnt necessarily give positive identification

o Reports may include off-state power draw if requested

LM-79 Content

Absolute and relative photometryfor other (non-SSL) technologies

Lamp, ballast and luminaire treated separately

Luminaire output and efficacy a function of

Luminaire efficiencyate amp umens

Ballast factor

-must be tested

Over 100% efficiency for some T5HO luminaires?!



21/29

LM-79 Content

Absolute and relative photometry methods do not work for SSL products []LED lamp sources are not designed to beremove rom e um na re.

o Absolute photometry required due to significantde endence on thermal mana ement

Hence the heat sinks often visible on LEDproducts

No standard means of determining/using rated lamp lumens for LED sources



22/29

Product Groups/Families

So test every possible variation?... different correlated color temperatures (CCTs),ENERGY STAR will allow those products to begroupe oge er, so ong as epackage(s)/module(s)/array(s), drive current,

electronics, and thermal management are otherwiseidentical. At a minimum, manufacturer must submit oneset of LM-80, In-situ Temperature Measurement Test

-

product version with the lowest CCT.

Variations in optics/distributions are allowed



23/29


Creating Product Groupsidentify the specific model used for testing to representthe entire group. When choosing this test sample, DOEa v ses app can s o c oose e var a on w c w have the most difficultymeeting the ENERGY STAR

criteria.



24/29


Further clarification of allowable test-sharing per DLC QPLProduct Famil criteria

o Same LED chip as tested/accepted model except withdifferent phosphor that produces a higher CCT thane es e accep e mo e

o Exterior housing has a different color-

symmetric with the opposite end-mounted model

To Be Continued

Locate the following

-

Needed for ENERGY STAR Option 1 compliancepath for lumen and color maintenance Not needed for Option 2, which substitutes two

LM-79 testso o Another after 6,000 hours of operation per

ENERGY STAR re uirements
