LUXEON K

Plug and play matrix platform solution

with precise flux, V

and color

LUXEON K delivers high flux at high efficacy in a small, easy-to-use

package. The high lumen density enables high light output in thermally

and space constrained systems (like retrofit lamps) and high efficiency in

systems aiming for high energy efficiency (such as downlights). The small

size bolt-down package enables simple assembly in space constrained

systems. With

Freedom from Binning,

every LUXEON K white product falls

within a single 3-step MacAdam ellipse positioned around the center

point of the ANSI nominal CCT bins to deliver tight CCT control to ensure

consistency in system color point. In addition, these parts deliver the

lumen maintenance and reliability that all LUXEON LEDs are renowned for.

General Information

Product Nomenclature

LUXEON K products are specified and binned “hot” (T

= 85°C) under conditions comparable to those found in

“real-world” lighting products.

The part number designation is explained as follows:

LXKA-PBCD-EFGHJ

Where:

—

O O

R L

D O

ER N

A E

B R

designates minimum CRI performance (value 8 = 80 minimum, value 9 = 90 minimum, value 0 for

Royal Blue)

designates color (value W = White, value R = Royal Blue)

C, D —

E, F —

G, H —

—

emitter count

denotes a flux upgrade (e.g, A, B, C, etc)

Therefore, 3000K products specified at 350mA 85°C follow the part numbering scheme:

L X K 8 - P W 3 0 - 0 0 0 4 for LUXEON K White 3000K 4-up

L X K 8 - P W 3 0 - 0 0 0 8 for LUXEON K White 3000K 8-up

L X K 0 - P R 0 4 - 0 0 0 8 for LUXEON K Royal Blue 8-up

designates nominal ANSI CCT (value 27 = 2700K, 30 = 3000K, 35 = 3500K, 40 = 4000K, 50 = 5000K,

and 04 = Royal Blue 447.5nm - 452.5nm peak wavelength)

custom spec designation or multi-junction designation (F - Number of strings, H number of emitters,

for example 0206, 2 strings of 3 = total emitters of 6)

Average Lumen Maintenance Characteristics

Lumen maintenance for solid-state lighting devices (LEDs) is typically defined in terms of the percentage of initial

light output remaining after a specified period of time. Lumileds projects that LUXEON K products will deliver, on

average, 70% lumen maintenance (L70) at 50,000 hours of operation at a forward current of up to 700mA. This

projection is based on constant current operation with junction temperature maintained at or below 125°C. This

performance is based on independent test data, 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.

Environmental Compliance

Lumileds is committed to providing environmentally friendly products to the solid-state lighting market. LUXEON K

is compliant to the European Union directives on the restriction of hazardous substances in electronic equipment,

namely the RoHS directive. Lumileds will not intentionally add the following restricted materials to the LUXEON K:

lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers

(PBDE).
