Typical 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.
