Cree® XLamp® CXB3590 LED
PRODUCT DESCRIPTION
The XLamp® CXB3590 LED Array is
the brightest member of the second
generation of the CXA family that
delivers up to 30% higher efcacy
and up to 20% higher lumens than the
rst generation in the same LES. The
higher performance second generation
CXA LED Arrays provide a drop-in
performance upgrade to existing
CXA LED designs to shorten product
development time. Available in 2‑step,
3-step and 5-step EasyWhite® bins,
the CXB3590 LED delivers high lumen
output and high efcacy in a single,
easy-to-use package that eliminates the
need for reow soldering.
The CX Family LED Design Guide
provides basic information on the
requirements to use the CXB3590 LED
successfully in luminaire designs.

XLamp® CXB3590 LED
OPERATING LIMITS
The maximum current rating of the CXB3590 depends on the case temperature (Tc) when the LED has reached thermal equilibrium under
steady‑state operation. The graphs shown below assume 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 17 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 18 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 20).
• Cree XLamp CXB3590 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.
* For 80 CRI minimum LEDs, CRI R9 minimum is 0 with a ±2 tolerance. For 90 CRI minimum LEDs, CRI R9 typical is 60.
** Flux values @ 25°C are calculated and for reference only.

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 20).
• Cree XLamp CXB3590 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.
* For 80 CRI minimum LEDs, CRI R9 minimum is 0 with a ±2 tolerance. For 90 CRI minimum LEDs, CRI R9 typical is 60.
** Flux values @ 25°C are calculated and for reference only.

XLamp® CXB3590 LED
THERMAL DESIGN
The CXB 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 CXB LED is being operated within its designed limits. LES temperature measurement provides additional verication of
good thermal design. Please refer to page 22 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 CXB 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 CXB LEDs successfully
in luminaire designs.
To keep the CXB3590 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 each 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 as specications.
