Electrical and functional safety
TRILUX luminaires correspond to the statutory
requirements of the EU low-voltage
guideline and the EU EMC directive and thus
bear the CE label. They correspond to the
regulations of EN 60598 and have the ENEC
label from the VDE test and certification
board primarily as standard version.
In addition to electrical safety, we test all
materials used in our laboratories with
regard to stability and their resistance to
Ignition of high-pressure lamps
High-pressure lamps generally require a
special ignitor, which generates an ignition
voltage of approx. 5 kV, in addition to the current-limiting
reactor. A built-in timer limits
the ignition time to the lamp-specific time.
After that, any attempts to start the lamp will
be interrupted. Doing so ensures, on the one
hand, a safe ignition of the lamp and, on the
other hand, prevents continual attempts to
ignite faulty lamps.
The “inner resistance” increases noticeably
due to the high internal temperature of highpressure
lamps. If a lamp goes out, e.g. due
to a short voltage drop, it must cool down for
up to 15 minutes in order to be switched
back on using the normal ignitor.
All luminaires for high-pressure discharge
lamps are equipped with interference
ignitors with automatic cut-off (timer). The
automatic cut-off prevents constant ignition
attempts in case of a defective lamp. The
time interval for ignition attempts is selected
in such a way that after a brief power failure
a reignition of intact high-pressure sodiumvapour
lamps and metal halide lamps is
ensured. If a stable lamp operation is not

controls secure the high quality standard of
our products. During the long service life
of outdoor lighting installations, there is the
possibility that luminaires could be damaged.
TRILUX guarantees a reliable replacement
part supply. For instance, high impactresistant
luminaires made of PMMA are
usually still available at least 10 years after
a luminaire series is discontinued.

made after a voltage-free switching.
