Info: Light emitting diodes (LEDs)
When operated in the forward direction the LEDs light.
They are available in several different versions (differing in
colour, size, form, luminosity, maximum current, voltage
limits). The longer lead of wired LEDs is normally the
anode (positive pole). With SMD-LEDs the cathode
normally is shown by a mark on the housing.
When using LEDs you always have to limit the current conduction (e.g.
by mounting a series resistor), otherwise they will be damaged after a
short operating duration. There are series resistors integrated on the
double flashlight PCB. Thus it is possible to connect LEDs directly.
Connecting several LEDs to one output
You can connect two LEDs of the same type in parallel or several LEDs
in series to each of the two outputs. The maximum number of LEDs
you can connect in series to one PCB depends on the voltage supplied
and the fluorescent colour of the LEDs.
