Cree® XLamp® CXA3050 LED

PRODUCT DESCRIPTION

The XLamp® CXA3050 LED array

expands Cree’s family of high‑ux,

multi‑die integrated arrays, offering high

performance in an easy‑to‑use platform.

With XLamp LED lighting‑class reliability,

the CXA3050’s uniform emitting

surface enables both directional and

non‑directional lighting applications and

luminaire and lamp designs. Available

in 2‑step, 3‑step and 4‑step color

consistency, and featuring a 23‑mm

optical source, the CXA3050 brings new

levels of ux and efcacy to this form

factor.

The CX Family LED Design Guide

provides basic information on the

requirements to use the CXA3050 LED

successfully in luminaire designs.

FEATURES

• Available in 4‑step, 3‑step and 2‑step

EasyWhite® bins at 2700K, 3000K,

* Refer to the Operating Limits section.

OPERATING LIMITS

The maximum current rating of the CXA3050 depends on the case temperature (Tc) when the LED has reached thermal equilibrium under

steady‑state operation. The graph shown below assumes that the system design employs good thermal management (thermal interface

material and heat sink) and may vary when poor thermal management is employed. Please refer to the Mechanical Dimensions section

on page 14 for the location of the Tc measurement point.

Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree recommends a

maximum LES temperature of 135°C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 15 for more

information on LES temperature measurement.

Notes

• Cree maintains a tolerance of ±7% on ux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a tolerance of ±2 on CRI

measurements. See the Measurements section (page 16).

• Cree XLamp CXA3050 LED order codes specify only a minimum ux bin and not a maximum. Cree may ship reels in ux bins higher than the minimum

specied by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specied by the order code.

* Flux values @ 25°C are calculated and for reference only.

RELATIVE LUMINOUS FLUX

The relative luminous ux values provided below are the ratio of:

• Measurements of CXA3050 at steady‑state operation at the given conditions, divided by

• Flux measured during binning, which is a pulsed measurement at 1400mA at TJ = 85°C.

For example, at steady‑state operation of Tc = 25°C, IF = 1600mA, the relative luminous ux ratio is 120% in the chart below. A CXA3050

LED that measures 6000lm during binning will deliver 7200lm (6000 * 1.2) at steady‑state operation of Tc = 25°C, IF = 1600mA.

XLamp® CXa3050 LED

THERMAL DESIGN

The CXA family of LED arrays can include over a hundred different LED die inside one package, and thus over a hundred different junction

temperatures (TJ). Cree has intentionally removed junction‑temperature‑based operating limits and replaced the commonplace maximum

TJ calculations with maximum ratings based on forward current (IF) and case temperature (Tc). No additional calculations are required to

ensure that the CXA LED is being operated within its designed limits. LES temperature measurement provides additional verication of

good thermal design. Please refer to page 2 for the Operating Limit specications.

There is no need to calculate for TJ inside the package, as the thermal management design process, specically from TSP to ambient

(Ta), remains identical to any other LED component. For more information on thermal management of Cree XLamp LEDs, please refer to

the Thermal Management application note. For CXA soldering recommendations and more information on thermal interface materials

(TIM), LES temperature measurement, and connection methods, please refer to the Cree XLamp CX Family LEDs soldering and handling

document. The CX Family LED Design Guide provides basic information on the requirements to use Cree XLamp CXA LEDs successfully

in luminaire designs.

To keep the CXA3050 LED at or below the maximum rated Tc, the case to ambient temperature

thermal resistance (R_c‑a) must be at or below the maximum R_c‑a value shown on the following

graph, depending on the operating environment. The y‑axis in the graph is a base 10 logarithmic

scale.

As the gure at right shows, the R_c‑a value is the sum of the thermal resistance of the TIM (R_tim)

plus the thermal resistance of the heat sink (R_hs).

NOTES

Measurements

The luminous ux, radiant power, chromaticity, forward voltage and CRI measurements in this document are binning specications only

and solely represent product measurements as of the date of shipment. These measurements will change over time based on a number

of factors that are not within Cree’s control and are not intended or provided as operational specications for the products. Calculated

values are provided for informational purposes only and are not intended or provided as specications.

Please read the LED Reliability Overview for details of the qualication process Cree applies to ensure long‑term reliability for XLamp

LEDs and details of Cree’s pre‑release qualication testing for XLamp LEDs.

Lumen Maintenance

Cree now uses standardized IES LM‑80‑08 and TM‑21‑11 methods for collecting long‑term data and extrapolating LED lumen maintenance.

For information on the specic LM‑80 data sets available for this LED, refer to the public LM‑80 results document.

Please read the Long‑Term Lumen Maintenance application note for more details on Cree’s lumen maintenance testing and forecasting.

Please read the Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect

the LED junction temperature.

RoHS Compliance

The levels of RoHS restricted materials in this product are below the maximum concentration values (also referred to as the threshold

limits) permitted for such substances, or are used in an exempted application, in accordance with EU Directive 2011/65/EC (RoHS2), as

implemented January 2, 2013. RoHS Declarations for this product can be obtained from your Cree representative or from the Product

Ecology section of the Cree website.

REACh Compliance

REACh substances of very high concern (SVHCs) information is available for this product. Since the European Chemical Agency (ECHA)

has published notice of their intent to frequently revise the SVHC listing for the foreseeable future, please contact a Cree representative to

insure you get the most up‑to‑date REACh SVHC Declaration. REACh banned substance information (REACh Article 67) is also available

upon request.

UL® Recognized Component

This product meets the requirements to be considered a UL Recognized Component with Level 4 enclosure consideration. The LED

package or a portion thereof has been investigated as a re and electrical enclosure per ANSI/UL 8750.

Vision Advisory

WARNING: Do not look at an exposed lamp in operation. Eye injury can result. For more information about LEDs and eye safety, please

refer to the LED Eye Safety application note.
