What accessories
are needed for
OSRAM DULUX
lamps?
®
As it is the case with fluorescent lamps, OSRAM DULUX
(CFLs) require suitable control gears. A distinction is made between lamps with two-pin
bases for operation on conventional (magnetic) control gear (CCG) and lamps with four-
pin bases for operation on electronic control gear (ECG).
With conventional control gear, a choke is used to limit the current and, in conjunction
with the starter housed in the lower section of the base (on OSRAM DULUX
to ignite the lamp. OSRAM DULUX
starter.
OSRAM DULUX
need special conventional control gear, adjusted to a lamp current of 220 mA. Operation
of these lamps on CCG for L 18 W fluorescent lamps with a lamp current of 370 mA will
overload the lamps. This will cause serious blackening of the lamp glass in the electrode
region and reduce the life of the lamps considerably.
Conventional control gear is available in different versions (with integrated lampholder,
for example, or integrated in the mains plug). With some types of lamp, it is possible to
connect two lamps in series in conjunction with suitable control gear.
CCG operation is generally an inductive form of operation. In connection with suitable
close-tolerance capacitors, capacitive operation (choke and capacitor in series) is also
possible. To maintain the prescribed operating and preheating values, close-tolerance
capacitors (± 2 %) and chokes (± 1,5 %) from renowned manufacturers are needed for
series compensation – dielectric strength of the capacitors 450 V ac. However, this
mode of operation is suitable only for a few types of lamp (see 3.2).
In addition to what is generally refferred to as standard control gear, the group of induc-
tive control gear includes low-loss gear (LLG). As their name suggests, this type of con-
trol gear is characterised by its low power loss.
Operating lamps on electronic control gear is a much better option. Apart from the
benefits of more comfortable light, longer lamp life and greater luminous efficacy from
the system (lamp + ECG), the functions of ignition, current limitation and compensation
are all integrated in the ECG. ECGs are also suitable for operation on direct current
(which means they can be used in emergency lighting systems) and comply with safety
standards (automatic disconnection of faulty lamps, etc.). There are ECG models for
most single and double-lamp arrangements. Some models have an integrated lamphol-
der (DULUXTRONIC
