Lumileds maintains a tolerance of
+/-0.06 Volts per LED for voltage
measurements.
Dynamic resistance is the inverse of the
slope in linear forward voltage model
for LEDs. See Figures 2a and 2b.

To determine the junction temperature,
multiply by total array power. For best
optical and lifetime performance,
additional heat sinking is required.

Proper current derating must be
observed to maintain junction
temperature below the maximum.
For more information, consult Luxeon
OEM Guide, available upon request.
LEDs are not designed to be driven in
reverse bias. Please consult Lumileds’
Application Brief AB11 for further
information.
