Product Nomenclature
LUXEON K2 with TFFC LEDs are tested and binned at 1000mA.
The part number designation is explained as follows:
L X K 2 A B C D E F G H for Emitter
L 2 K 2 A B C D x x E F G H for Star
Where:
A 鈥?designates radiation pattern (Value P for Lambertian emitter, M for Lambertian Star product)
B 鈥?designates color (see Philips Lumileds AB21)
C 鈥?designates color variant (0 for direct colors, C for Cool White)
D 鈥?designates test current (value 4 for 1000 mA)
E 鈥?Reserved for future offerings
FGH 鈥?minimum luminous flux (lm) or radiometric power (mW) performance
x x indicates array description for Level 2 Star Product (11 for 1x1 array)
Therefore, products tested and binned at 1000mA follow the part numbering scheme:
L X K 2 P x x 4 x x x x (L 2 K 2 M x x 4 1 1 x x x x for Star)
Average Lumen Maintenance Characteristics
Lifetime for solid state lighting devices (LEDs) is typically defined in terms of lumen maintenance鈥攖he percentage of initial light
output remaining after a specified period of time.
Philips Lumileds projects that white LUXEON K2 with TFFC products will deliver, on average, 70% lumen maintenance at 50,000
hours of operation at a forward current of 1000mA. This projection is based on constant current operation with junction tempera
ture maintained at or below 120擄C.
This performance is based on independent test data, Philips Lumileds historical data from tests run on similar material systems,
and internal LUXEON reliability testing. Observation of design limits included in this data sheet is required in order to achieve this
projected lumen maintenance.
More information about lifetime and reliability can be found in the LUXEON K2 Reliability Datasheet on the Philips Lumileds
web site.
Environmental Compliance
Philips Lumileds is committed to providing environmentally friendly products to the solid state lighting market. LUXEON K2 with
TFFC LEDs are compliant to the European Union directives on the Restriction of Hazardous Substances in electronic equipment,
namely the RoHS directive. Philips Lumileds will not intentionally add the following restricted materials to LUXEON K2 with TFFC
LEDs: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers
(PBDE).
