LUXEON K2 Datasheet DS51 (7/07)

Product Nomenclature

The LUXEON K2 is available in two configurations, one tested and binned at 350 mA and a second tested and binned at 1000

mA. Due to production distribution and variance it is difficult to accurately correlate product performance across a broad drive

current range. This is one of the reasons Philips Lumileds has elected to offer multiple test current options of the LUXEON K2 to

better service our customers.

The part number designation is explained as follows:

L X K 2 A B C D E F G for LUXEON K2 Emitter

L 2 K 2 A B C D E F G H for LUXEON K2 Star

Where:

A — designates radiation pattern (value P for Lambertian)

B — designates color (see Philips Lumileds AB21)

C — designates color variant (1 for direct colors and Cool White, N for Neutral White, and W for Warm White

D — designates test current (value 2 for 350 mA, value 4 for 1000 mA)

E — designates minimum flux bin for LUXEON K2 Emitter (see Philips Lumileds AB21)

F — designates minimum flux bin for LUXEON K2 Star product (see Philips Lumileds AB21), Reserved for future product offer

ings in LUXEON K2 Emitter

G and H — Reserved for future product offerings.

Products tested and binned at 350 mA follow the part numbering scheme:

L X K 2 x x x 2 x x x (L2K2 xxx2 11 Bxxx for LUXEON K2 Star)

For these products typical performance is also listed for 700 mA operation.

Products tested and binned at 1000 mA follow the part numbering scheme:

L X K 2 x x x 4 x x x (L2K2 xxx4 11 Bxxx for LUNXEON K2 Star)

For these products typical performance is also listed for 1500 mA operation.

Both versions of this product are capable of operation over the entire drive current range, up to 1500 mA for cool white,

neutral white, warm white, green, cyan, blue and royal blue and up to 700 mA for red, red orange and amber.

In addition, multiple minimum performance levels of both products are available. Digit "E" (Digit "F" for K2 Star Product) in the

part numbering scheme above, specifying the minimum performance flux bin, designates the performance option.

Average Lumen Maintenance Characteristics

Lifetime for solid state lighting devices (LEDs) is typically defined in terms of lumen maintenance—the percentage of initial light

output remaining after a specified period of time.

Philips Lumileds projects that white LUXEON K2 products will deliver, on average, 70% lumen maintenance at 50,000 hours of

operation at a forward current of 1000 mA. This projection is based on constant current operation with junction temperature

maintained at or below 120°C. Philips Lumileds projects that green, blue, cyan and royal blue LUXEON K2 products will deliver,

on average, 70% lumen maintenance at 50,000 hours of operation at a forward current of 1000 mA. This projection is based on

constant current operation with junction temperature maintained at or below 150°C. Philips Lumileds projects that red, red

orange and amber LUXEON K2 products will deliver, on average, 70% lumen maintenance at 50,000 hours of operation at a

forward current of 350 mA. This projection is based on constant current operation with junction temperature maintained at or

below 120°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.
