13 thermal design the cxa family of l e d arrays can include over a hundred different le d 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 cxa l e d is being operated within its designed limits. please refer to page 2 for the operating limit specifcation. cree has measured the temperature at the bottom of the package, commonly referred to as the solder point (t sp ), and found this value to be equivalent to the temperature at the tc location at the top of the package once the l e d has reached thermal equilibrium. there is no need to calculate for t j inside the package, as the thermal management design process, specifcally from t sp to ambient (t a ), remains identical to any other l e d component. for more information on thermal management of cree xlamp l e ds, please refer to the xlamp thermal m anagement application note at www.cree.com/xlamp_app_notes/thermal_management. for cxa soldering recommendations and more information on thermal interface materials (ti m ) and connection methods, please refer to the cree xlamp cxa family le ds soldering and handling document at www.cree.com/xlamp_app_notes/cxa_sh. to keep the cxa1820 l e d 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 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 cxa1820 0.01 0.10 1.00 10.00 100.00 350 450 550 650 750 850 950 1050 maximum r_c - a current (ma) ta = 25 c ta = 55 c ta = 85 c ta = 105 c copyright ? 2013 cree, inc. all rights reserved. the information in this document is subject to change without notice. cree ? , the cree logo, xlamp ? and easywhite ? are registered trademarks of cree, inc. xlamp cxa1820 led
