LED Lifetime Prediction


IES TM-21-2011

Projecting Long Term Lumen Maintenance of LED Light Sources

LM-80

TM-21

(testing) + (projection) =

Useful

Lifetime

Prediction

• Supplements IES LM-80 raw test data to provide LED lifetime

projections that are consistent and understandable

• Committee included Cree, Philips Lumileds, Nichia, OSRAM,

U.S. Dept Of Energy, NIST & PNNL

• TM-21 provides two major functions:

1. Extrapolate a single LM-80 data set to estimate Lxx lifetime

2. Interpolate a matched LM-80 data set (same current, 3

different temperatures) for a specific temperature, and

estimate Lxx lifetime

Copyright © 2011, Cree, Inc. pg. 20


TM-21 New Concepts

Lxx(Yk)

– xx = % lumen maintenance (e.g., L70 or L50)

– Y = duration of LM-80 test used for the projection

Calculated & Reported Lifetime

– Calculated = what the extrapolation says

– Reported = Calculated, limited by LM-80 test

duration

(6x LM-80 for sample size ≥ 20)

Lifetimes always rounded to 3 significant digits

– 36,288 36,300

– 215,145 215,000

Time (hours)

Projection Method:

• Any Lxx value can be calculated from & β:

– TM-21 requires that all lifetime projections include & β

• Exponential least squares curvefit

through the averaged values

• Curve fit through last 5000

hours or 50% of LM-80 duration,

whichever is longer

• Creates 2 important values:

= decay factor

β = intercept

• Some data sets have positive slope in the projection period (


A Real TM-21 Example (10k)

• Note: Reported Lifetime limited to 6x LM-80 duration (10k hrs)

• Math works for any Lp (L70, L80, L90…)

Copyright © 2011, Cree, Inc. pg. 23


TM-21 Temperature Interpolation

• Interpolation between matched LM-80 data sets

– Same current, 3 different temperatures: 55°C, 85°C & manufacturer’s choice

• Lxx calculation possible on interpolated case (Tsi)

• & β for Tsi are derived from next higher & lower LM-80 data sets

– Both sets valid ( > 0): by Arrhenius interpolation; β = sqrt(β1*β2)

– One set valid ( > 0): use & β of the valid set

– Neither set valid ( > 0): use Reported Lifetime rules
