cld-ds117 rev 0g cree ? xlamp ? cxb1507 led pro duc t d escrip tion the xlamp ? cxb1507 l e d array is a member of the second generation of the cxa family that delivers up to 30% higher effcacy and up to 20% higher lumens than the frst generation in the same l e s. the higher performance second generation cxa l e d arrays are compatible with the frst generation, providing a drop-in performance upgrade to existing cxa l ed designs to shorten the luminaire design cycle and improve time to market. available in 2?step, 3?step and 5?step easywhite ? bins, the cxb1507 led delivers high lumen output and high effcacy in a single, easy?to?use package that eliminates the need for refow soldering, enabling lighting manufacturers to rapidly address small form factor lighting applications. the cx family l e d design guide provides basic information on the requirements to use the cxb1507 l ed successfully in luminaire designs. fe atures ? 9- mm optical source ? mechanical and optical design consistent with other cxa15 and cxb15 leds ? available in 70 ?, 80?and 90?minimum cri options ? cree easywhite ? 2?, 3? and 5?step binning ? forward voltage options: 18?v class & 36-v class ? 85?c binning and characterization ? e xtremely uniform color over viewing angle ? top-side solder connections ? thermocouple attach point ? nema ssl ? 3 2011 standard fux bins ? rohs and re ach compliant ? ul ? recognized component (e349212) t able of cont e nts characteristics ............................................ 2 operating limits .......................................... 3 flux characteristics, easywhite ? order codes and bins ? 18?v ................................. 4 flux characteristics, easywhite ? order codes and bins ? 36?v ................................. 6 relative spectral power distribution ......... 8 e lectrical characteristics ............................ 9 relative luminous flux ............................ 10 typical spatial distribution ...................... 12 performance groups - brightness .......... 12 performance groups - chromaticity ....... 13 cree easywhite ? bins plotted on the 1931 cie curve ......................................... 14 bin and order code formats ................... 15 mechanical dimensions .......................... 15 thermal design ........................................ 16 notes ........................................................ 18 packaging ................................................. 19 product family data sheet copyright ? 2015-2016 cree, inc. all rights reserved. the information in this document is subject to change without notice. cree ? , xlamp ? and easywhite ? are registered trademarks and the cree logo is a trademark of cree, inc. ul ? and the ur logo are registered trademarks of ul llc. cree, inc. 4600 silicon drive durham, nc 27703 usa tel: +1.919.313.5300 www . cree . c om/x lamp

3 ope rating li m its the maximum current rating of the cxb1507 is dependent 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 15 for the location of the tc measurement point. cxb1507 - 18 v 0 100 200 300 400 500 600 700 800 0 25 50 75 100 125 150 if (ma) case temperature ( c) 18 v cxb1507 - 36 v 0 50 100 150 200 250 300 350 400 0 25 50 75 100 125 150 if (ma) case temperature ( c) 36 v copyright ? 2015-2016 cree, inc. all rights reserved. the information in this document is subject to change without notice. cree ? , xlamp ? and easywhite ? are registered trademarks and the cree logo is a trademark of cree, inc. ul ? and the ur logo are registered trademarks of ul llc. xlamp ? cxb1507 led

16 therm al 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 (t j ). cree has intentionally removed junction ? temperature? based operating limits and replaced the commonplace maximum t j calculations with maximum ratings based on forward current (i f ) and case temperature (tc). no additional calculations are required to ensure the cxb led is being operated within its designed limits. please refer to page 3 for the operating limit specifcation. there is no need to calculate for t j inside the package, as the thermal management design process, specifcally from solder point (t sp ) to ambient (t a ), 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) and connection methods, please refer to the cree cx family l e ds soldering and handling document . the cx family l ed design guide provides basic information on the requirements to use cree xlamp cxb l e ds successfully in luminaire designs. to keep the cxb1507 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 graphs, depending on the operating environment. the y - axis in the graphs is a base 10 logarithmic scale. as the fgure 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). r_j-c tc r_tim r_hs ta r_j-c tc r_c-a ta cxa1507 - 18 v 0.01 0.10 1.00 10.00 100.00 200 250 300 350 400 450 500 550 600 650 700 750 maximum r_c - a current (ma) ta = 25 c ta = 55 c ta = 85 c ta = 105 c 18 v copyright ? 2015-2016 cree, inc. all rights reserved. the information in this document is subject to change without notice. cree ? , xlamp ? and easywhite ? are registered trademarks and the cree logo is a trademark of cree, inc. ul ? and the ur logo are registered trademarks of ul llc. xlamp ? cxb1507 led
