Dynamic resistance is the inverse of
the slope in linear forward voltage
model for LEDs. See Figures 3a and
3b.
Measured between 25
110
and I
To determine the junction
temperature, multiply by total array
power. Due to the high packing
density of the Floods, the board
temperature rise is significant and
must always have additional heat
sinking at nominal operating
conditions.
Proper current derating must be
observed to maintain junction
temperature below the maximum.
For more information, consult Luxeon
Design Guide, available upon request.
LEDs are not designed to be driven in
reverse bias. Please consult Lumileds’
Application Brief AB11 for further
information.
