4. Operation overview
Possibilities of use
The carriage lighting WIB-11 to -13 can be connected directly to a
vehicle´s current collector or the function output of a digital vehicle
decoder. For the power supply analogue a.c. or d.c. transformers or
digital boosters can be used.
Design of the PCB
The carriage lighting WIB-11 to -13 have inserted 8 LEDs. The colours
of lighting are:
WIB-11: yellow
WIB-12: bright white
WIB-13: or warm white
The length of the PCB as well as number and layout of the LEDs
correspond to the carriage lighting WIB-31 to -33 with integrated
function decoder which are available as well in the fluorescent colours
yellow (WIB-31), bright white (WIB-32) and warm white (WIB-33).
Thus the (analogue) carriage lighting of the 10er-series is suitable
especially for combining with the lighting of the 30s series in a block
train.
Flickering protection
An integrated smoothing capacitor supplies the LEDs when short
current interruptions occur, which prevents the lighting from flickering
when points or smudges on the rails are crossed. In case the integrated
smoothing capacitor is not sufficient, you can connect an additional
external bridging capacitor and / or an external gold cap.
Dividing and shortening the PCB
The 240 mm long PCB (with 8 LEDs) can be divided into two 100 %
equivalent parts of approx. 105 mm each (with 4 LEDs). Each part has:
a soldering jumper to set the switching on mode for the LEDs:
smooth brightening of the LEDs or
simulation of flickering fluorescent lamps;
a trimmpot to set the brightness;
connecting points for two external LEDs (e.g. for the train rear
lighting);
an integrated smoothing capacitor as a flickering protection;
connecting points for an external bridging capacitor and an external
gold cap to supply the LEDs when current interruptions occur.
Each of the two parts of the PCB can be shortened by 30 mm to
approx. 210 mm (with 7 LEDs) or 75 mm (with 3 LEDs). The remaining
segment with one LED can be used e.g. as a driver´s cab lighting or as
lighting for the passenger entrance, by adding a small circuit (not
included in the package).
