ypical LEDs Load Mapping
Since
the output power is voltage battery limited (see
Figure 5),
one shall arrange the LED to cope with a specific
need.
In particular
, since the power cannot extend 600 mW
under
realistic
battery
supply
, powering ten LED can be
achieved by a series/parallel combination as depicted in
Figure 36.
