oPErating LiMits
The maximum current rating of the CXB3070 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 11 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 135C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 12 for more
information on LeS temperature measurement.
