General Information
Part Number Nomenclature
LUXEON CoB is tested and binned hot at T
j
= 85°C with a current pulse duration of 20ms.
The part number designation is explained as follows:
L H C A – B B C C – D D E E (Traditional)
Where:
A — designates the generation of the product family
B B — designates ANSI color point (e.g. 30 for 3000K)
C C — designates minimum CRI level (e.g. 80 for minimum 80CRI)
D D E E — designates product conguration (e.g. 1203 for the 1000-2000 lumen package)
L 2 C A – B B C C D D E E F F G G G (New Part Number Scheme for New Products)
Where:
A — designates the generation of the product family
B B — designates ANSI color point (e.g. 30 for 3000K)
C C — designates minimum CRI level (e.g. 80 for minimum 80CRI)
D D E E — designates product conguration (e.g. 1202 for the low lumen package)
F F — designates light emitting surface (e.g. 06 for 6mm LES)
G G G — designates manufacturing technology (e.g. AC0 for crisp white)
Therefore 3000K, 80CRI LUXEON CoB products will be:
L H C 1 – 3 0 8 0 – 1 2 0 3
L 2 C 1 – 3 0 8 0 1 2 0 2 0 6 A 0 0
CAT codes of LUXEON CoB:
3S: color within 3-step MacAdam ellipse
5S: color within 5-step MacAdam ellipse
Average Lumen Maintenance Characteristics
Lumen maintenance for solid-state lighting devices (LEDs) is typically dened in terms of the percentage of
initial light output remaining after a specied period of time. Lumileds projects that LUXEON CoB will deliver—on
average—70% lumen maintenance (L70) at 50,000 hours of operation at its nominal, tested conditions. Observation
of design limits included in this data sheet is required in order to achieve this projected lumen maintenance. This
performance is based on independent test data, Lumileds historical data from tests run on similar material systems,
and internal LUXEON reliability testing.
Environmental Compliance
Lumileds is committed to providing environmentally friendly products to the solid-state lighting market. LUXEON CoB
is compliant to the European Union directives on the restriction of hazardous substances in electronic equipment,
namely the RoHS and REACH directives. Lumileds will not intentionally add the following restricted material to the
LUXEON CoB: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated
diphenyl ethers (PBDE).
