The 140m long Pont y Werin bridge
spans the marina in Cardiff Bay,
providing access for cyclists and
pedestrians between the International
Sports Village in Cardiff Bay and
Penarth. Otherwise known as the
“Peoples Bridge” the £4.5 million
structure is split into 4 spans, of which
1 span rises to allow vessels to pass
underneath.
To illuminate the bridge
deck Chromatica designed,
manufactured and installed
a high flux LED luminaire
system. Luminaires are
mounted on both sides of
the bridge deck within the
33.7mm rails that constitute
the
parapet
railing
system. This provides

remote from the lighting
fixtures, and form part of
the LV harness system.
By co-ordination with
the
bridge
fabricator,
Chromatica
designed
and installed the preassembled
harnesses
into the bridge structure,
with all of the necessary
luminaire cabling exiting
the pre-cut luminaire slots
in the correct locations.
The LV harness system
exits the parapet rails at
the end of each bridge
span, via galvanised steel
conduits for the fixed deck
spans and flexible stainless
steel conduits for the raise
and lower portion of the
bridge.
Each LV harness leads
to cavities with in the
bridge deck, where they
are supplied 29.5V DC via
intelligent AC/DC power
supplies.
The
remote
electronics
built
into
the LV harness running
through the bridge rails
automatically compensates
for voltage drop, ensuring
each luminaire receives the
correct forward voltage
and current to ensure their
reliable operation.
Luminiares are held within
the rails by stainless steel
retaining clips and screw
fasteners. Luminaires are
purposefully made a tight
fit to maintain a close gap
line between the luminaire
and slot aperture improving
the aesthetic appearance
of the finished installation.
