1.12 OSRAM ECG

Milestones

• For the first time in 1995, T5- fluorescent lamp systems with Cut-

off-technology have been introduced to the market.

Cut-off technology is the cut-off of the permanent filament

preheating after lamp ignition. This can be realized due to

modifications in the electronic circuit of the ECG. The result of the

Cut-off technology are less losses and optimized lamp operation.

• Four years later, in 1999, OSRAM sold the first reliable

MULTIWATT-ECG.

This operates all lamps with rated data.

• During the following years the trend of miniaturization continued and

the height of Electronic Control Gear was reduced by 30% from

30 mm to 21 mm.

In 2002, OSRAM is again the first manufacturer to introduce

MULTIWATT-ECG to operate FQ

…HO-fluorescent lamps High

Output in 21 mm height.

• In 2003, another novelty is brought to the T5-product segment: As

the first producer, OSRAM offers a 21 mm high 2-lamp ECG for

80 W HO-fluorescent lamps.

• In the beginning of 2004, the newest and most innovative member

of the T5-product family has been introduced: micro-controller

based ECG capable of operating T5-fluorescent lamps of equal

length regardless if it is a FH

…HE- or FQ

…HO-type. This micro-

controller especially developed under the co-operation with OSRAM

is responsible for clear lamp detection and lamp operation with

nominal data.

QUICKTRONIC INTELLIGENT, QTi make one MULTIWATT-ECG

possible for all T5-fluorescent lamps from 14 to 39 W no matter if

…HE- or FQ

…HO-types.
