Technical Datasheet DS102

LUXEON K

High Efficiency Arrays

Introduction

The LUXEON

K arrays in this datasheet deliver high flux at high efficacy in a small, easy to use package.

The high efficiency delivers high light output in thermally constrained systems like retrofit lamps and high

efficiency in systems like downlights aiming for high energy efficiency. The small size bolt down package

enables simple assembly in space constrained systems. LUXEON K is specified at real world operating

conditions, Tj 85°C. With Freedom From Binning, every LUXEON K falls within a single 3 McAdam ellipse

positioned around the center point of the ANSI nominal CCT bins to deliver tight Correlated Color

Temperature 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. This document contains the

performance data needed to design and engineer LUXEON K based applications.

General Information

Product Nomenclature

LUXEON K products are specified and binned “hot” under conditions comparable to those found in “real-world” lighting products. The test

conditions are at 350 mA D.C. with junction temperature at 85°C.

The part number designation is explained as follows:

L X KA - P B C D - E F G H

Where:

— designates minimum CRI performance (value 8 = 80 minimum, value 9 = 90 minimum)

— designates color (value W = White)

C, D — designates nominal ANSI CCT (value 27 = 2700K, 30 = 3000K, 35 = 3500K, 40 = 4000K, and 50 = 5000K)

E, F — custom spec designation

G, H — emitter count

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

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

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

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. Philips 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 700 mA. 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, 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.

Environmental Compliance

Philips 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. Philips 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).

Notes for Table 1:

- Philips Lumileds maintains a tolerance of ± 6.5% on luminous flux and ± 2 on CRI measurements.

- LUXEON K products with even higher luminous flux levels will become available in the future. Please consult Philips Lumileds or Future

Lighting Solutions for more information.

1. Test current is 350 mA for all LXKx-PWxx products.

2. Total angle at which 90% of total luminous flux is captured.

3. Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.

4. All white products are built with Indium Gallium Nitride (InGaN).
