Dear Reader,
Energy-saving in buildings is to be accelerated
by the new EU Directive on the
Energy Performance of Buildings, which
also addresses lighting installations.
More than 50% of the electrical energy
used in this sector can be saved by
electronic control gear and light control
systems in combination with modern
light sources and efficient luminaires.
In this context, the DALI standard for
dimmable control gear presents itself as
the ideal basis for combining energy efficiency
with flexibility and ease of operation.
Innovative gateways optimally integrate
dimmable DALI luminaires into building
systems equipment, regardless of
whether EIB, LON or other bus system
are used.
For smaller installations without building systems equipment, individual sensors,
pushbutton operation or multi-channel remote controls are sufficient. Solutions of
this kind increasingly centre on intelligent QTi DALI ECG, which can be controlled not
only via DALI, but equally by pushbuttons (Touch DIM) or sensors (Touch DIM Sensor).
It goes without saying that, alongside fluorescent and compact fluorescent lamps, it
is also possible to integrate halogen lamps into DALI systems via the HT DALI DIM
dimmer, as well as LEDs via the OT DALI converter. The great advantages of LEDs in
terms of colour and dynamic variation are leading to a host of new applications.
The new "intelligent ECG" (QUICKTRONIC INTELLIGENT) attracted a lot of interest
both at Light+Building in Frankfurt and the Light Fair in Las Vegas.
The intelligent, microprocessor-based "internal workings" automatically detect the
lamp wattage, this being a major advantage for HE and HO T5 fluorescent lamps, in
particular.
By using different lamps of identical length, luminaire manufacturers, dealers, facility
managers and end customers can achieve different lighting levels and thus differentiated
applications. The resultant flexibility, and the simultaneous reduction in the
variety of luminaires, is a benefit to all concerned.
Electronics is one of the keys to added-value products, taking us towards efficiency
and convenience in today's lighting industry.
As ever, I hope you enjoy reading this issue of our ECG SPOT!
Yours,
Hans-Peter Birkhofer – Marketing Manager, Electronic Control Gear

LEDs for illuminated advertising
Alternative with added value
LED systems are increasingly
establishing themselves in
illuminated advertising as an
innovative alternative to conventional
lamps, such as neon
tubes. This is particularly true
in applications dominated by
coloured light. This trend is
fuelled by the remarkable advantages
that the LED system
from OSRAM displays:
• Homogeneous illumination,
• Small dimensions for new
design options,
• Simple, flexible installation,
• Safe operation due to safety
extra-low voltage,
• Unproblematic operation at
low temperatures,
• Brilliant colour saturation,
• Energy-efficient operation,
• Low maintenance costs.
New OPTOTRONIC units also shine in outdoor applications
Fig. 1. Denmark's DK-Benzin oil corporation is going for LEDs and OPTOTRONIC
OT50/120-277/10E and OT75/120-277/24E
control gear at a glance
Convinced by these properties
is, for example, Denmark's
DK-Benzin oil corporation with
its extensive network of petrol
stations. In the framework of
repair work, the more than
250 petrol stations are being
converted from neon to LED
light. The features that swung
the balance in favour of the
LED system from OSRAM were
the greatly reduced power
consumption and the substantially
lower maintenance costs
compared to the solution based
on neon tubes.
Red and white BACKlight LED
modules are used, which fit
optimally into the profile developed
by VPI Skilte.
• Developed for outdoor use and encapsulated for protection
against ambient influences (degree of protection IP64)
• Multi-line voltage input from 120 V to 277 V for worldwide use
• The safety mechanisms integrated in the OPTOTRONIC control
gear for protection against short-circuits, excess temperature
and overloading guarantee safe operation of the LED system
• The output can be increased by parallel connection on
the secondary side
Comparison of the energy balance per petrol station
Neon system:50 m x 25 W/m = 1,250 W; at 4,500 hours
of operation per year = 5,625 kWh/a, i.e. 56.25 MWh
in ten years
LED system: 50 m x 10 W/m = 500 W; at 4,500 hours
of operation per year = 2,250 kWh/a, i.e. 22.50 MWh
in ten years
This results in energy savings of 33.75 MWh per petrol station in
ten years, or 1.1 million for 250 petrol stations and an assumed
electricity price of 0.13/kWh.
The connected load of the red
LED system is just 10 W/m,
compared to up to 25 W/m for
the neon version.
In addition, neon tubes have
to be reconditioned after
20,000 hours and the electrodes
replaced. In contrast,
the LED system guarantees
maintenance-free operation
for more than 50,000 hours,
resulting in longer maintenance
intervals.
The BACKlight LED modules
are operated via the new OT
50/120-277/10 E control gear.
Growing family
OSRAM has expanded the
OPTOTRONIC equipment family
to include two units suitable
for outdoor use:
the OT 50/120-277/10 E for
10 V LED modules and the
OT 75/120-277/24 E for 24 V
modules. The independent
LED converters of Safety
Class I are primarily characterised
by their robust design,
which makes them perfectly
suited to outdoor use. In
addition to protection against
moisture and dust (IP64), they
guarantee great reliability at
ambient temperatures of up to
60 °C and voltage pulses of
up to 3 kV.
Moreover, the "SMART POWER
SUPPLY" feature stands for

optimised operation of the
LED modules: intelligent control
keeps the lighting parameters
constant at both low and
high outdoor temperatures.
The addition of OPTOTRONIC
"E" - for "Exterior" - to the
control gear family offers optimum
prerequisites for use of
the LED system from OSRAM
in illuminated advertising and
other outdoor applications.

The fascination of colour
Farewell, drab grey!
When you think of wall systems,
the first thing that comes
to mind is usually grey,
unattractive partition walls -
covered with important notices
around desks - in the vast expanses
of gigantic open-plan
offices, or "lonely", inconspicuous,
free-standing walls in
the reception areas of companies
or hotels.
However, there are also more
elegant creative solutions. The
future holds the promise of
designs that are both colourful
and stylish. Combined with
optimised OPTOTRONIC ECG
and control systems, LINEARlight
Colormix LED modules
permit variable light solutions
for wall systems.
Creativity points the way
The innovative partition walls
were developed as part of a
joint research project by the
Baier & Demmelhuber engineering
office, the Faculty of
Building Realisation of Munich
University of Technology, OS-
RAM and other industry partners.
In the framework of the
project, LINEARlight Colormix
LED modules were integrated
in flexible mobile walls made
of solid glass. The result is
wall systems that are not only
colourful, but also have an
elegant look.
The partition walls consist of
sheets of glass that are sandblasted
or coated on one side
and mounted in an invisible
OSRAM ECG-SPOT 2/2004
4
Variable wall elements using the LED Colormix system
frame. The glass sheets and
the frames are bonded
together to produce a rigid
composite element.
The "Unicon" connectors give
the whole thing a special
"twist": on the one hand, they
can be used to join the individual
elements to each other.
On the other hand, they are
also designed to transmit and
carry all kinds of media, such
as electricity, data, water or
heat, from element to element.
Light-emitting diodes
cleverly integrated
The coloured LED light strips
are integrated in the lower
area of the space between the
sheets of glass, illuminating
the elements in bright colours.
The LED modules are accessible
via a small inspection port
on the side of the frame.
Thanks to their small dimensions,
the OPTOTRONIC
operating and control components
can also easily be
accommodated in the element
frame.
Control trilogy
Three options are available for
controlling the wall system:
• OT RGB 3-Channel DIM is a
1…10 V control unit for individual
control of the three
basic colours red, green and
blue. In this way, the colour
Fig. 1. Partition walls with LED systems offer new perspectives
of the RGB LED modules
can, for example, be controlled
and dimmed by remote
control or via a permanently
installed controller.
• The OT RGB Sequencer 3channel
PWM sequencer
creates the dynamic colour
change of RGB LED modules.
The speed of the
sequence can be controlled
via the 1…10 V control
input. If required, a specific
colour can also be set permanently
in this way.
Fig. 2. The wall systems look totally
unspectacular when unlit
The two 1...10 V control units
are used on the secondary
side of the power supplies, i.e.
wired between the OPTOTRO-
NIC control gear and the LED
modules.
• The third control option, the
OT DALI 25/220-240/24
RGB, permits the integration
of LED modules in DALI
light control systems. Mains
voltage converter, DALI interface
and PWM controller
are integrated in a single
unit in this case, i.e. one unit
is used for both operation
and control. Via the DALI
input, three output channels
can be addressed and thus
controlled individually via
DALI.

Fig. 3. The operating element likewise
has an elegant appearance
As a result, innovative, dynamic
solutions are created in a wide
variety of ways and integrated
into the interior design of the
building.
Fascinating appearance as
a result
The partition walls with integrated
LED modules create fascinating
colours with a futuristic
look. These unusual
lighting effects enhance any
office and make for a motivating
working climate.
LINEARlight Colormix LED modules
with impressive characteristics:
• Brilliant colour properties due to high colour saturation
• Very small dimensions
• Low power consumption and low heat generation
• Insensitive to low temperatures and impact
• Long service life
• Easy to connect
• Operation and control using OPTOTRONIC units
Available types:
LINEARlight Colormix OS-LM 01M-RGB
• Equipped with 30 three-colour LEDs
• Length 450 mm, width 11.5 mm
• Supply voltage 24 V DC
LINEARlight Colormix Flex on flexible circuit board material
• Equipped with 200 three-colour LEDs
• Length 4,000 mm, width 11.5 mm
• Supply voltage 24 V DC
The "WAVARIA" wall systems
meet the demands of modern
office and administration building
construction. In addition,
the luminous elements display
remarkable advantages, not
only in terms of economy and
function, but also from an
aesthetic point of view.
At Light+Building 2004, the
coloured-light walls received
the "Architecture and Techno-
logy" Innovation Award for
their functionality and innovative
design. The jury specifically
praised the integral
achievement of all the partners
involved in the project. The
main practical advantages of
the wall system are seen as
being the ease of assembly
and the high degree of prefabrication,
despite the wide
variety of elements. As a
result, the luminous wall is an
outstandingly successful
design element.

Consistently DALI
Perfect basis
OSRAM control gear with a
DALI interface is eminently
suitable as the basis for
innovative Light Management
Systems (LMS).
Different versions are available
for a wide range of light
sources: from fluorescent
lamps and halogen lamps,
all the way to LED modules.
Depending on the light solution
required, the corresponding
control gear can be controlled
via an OSRAM LMS light controller
or a DALI gateway from
partner companies.
DALI control gear from OSRAM
is characterised by its outstanding
coordination with the
respective lamp and by very
good dimming properties.
OSRAM offers a five-year
guarantee on the control gear
when using an OSRAM lamp
OSRAM ECG-SPOT 2/2004

in combination with OSRAM
control gear. The installation
must be registered for this
purpose. The exact terms of
the guarantee can be found
on the Internet at

Smart light management
systems
From a simple light button to
a multifunctional single-room
system, OSRAM offers the
right Light Management
Systems for every application
(Fig. 1), with emphasis on easy
commissioning and installation
every time. Depending on the
system, between one and 64
DALI ECG units can be integrated
and controlled singly or
in several groups.

Three-phase system and ECG
Power supply in European
systems
A line voltage of 230 V and a
frequency of 50 Hz are customary
in Europe.
Regardless of the primary
energy carrier selected, power
stations generate three-phase
current. The three-phase
system comprises the phase
conductors L1, L2 and L3, the
neutral conductor N and an
earth connection. The voltage
of each phase conductor to
the neutral conductor is 230 V
and is used for the majority of
consumers. Neutral conductor
and protective earth conductor
both have earth potential.
In this Y-connection (Fig. 1),
the neutral conductor supplies
the consumers, together with
L1, L2 and L3. The protective
earth conductor ensures the
personal safety, e.g. by earthing
metal housings. The
sinusoidal voltages of L1, L2
and L3 are each 120° out of
phase.

Fig. 1. Three-phase network with consumer
The voltage between two
phase conductors is usually
400 V, or 230 V in exceptional
cases, and is not suitable for
operating most commercially
available consumers. This
delta connection is customarily
used only in industry and in
drive systems. Given absolutely
uniform loading of the three
circuits, the current in the
neutral conductor is equal to
zero.
Spotlight on uniform
loading
Although network operators
aim for uniform loading of the
three circuits, this requirement
is only approximately met in
practice. If the loading of the
three circuits is non-uniform,
what is known as a compensating
current flows in the
neutral conductor.
When operated on a threephase
system, an input voltage
of 230 V is present at the electronic
control gear - provided

that a neutral conductor is
incorporated in the cable and
connected.
Effect of asymmetry
If the load in the three-phase
system is asymmetrical, and
the neutral conductor is not
corrected or connected incorrectly,
neutral point displacement
can occur (Fig. 2).
Since no neutral conductor
is connected, the total of the
conductor currents at the
neutral point is always zero.
To ensure that this condition
is met, phase voltages U1N,
U2N and U3N change their
magnitude, among other
things. This leads to what is
known as neutral point displacement
and an associated
overvoltage or undervoltage in
the three-phase system. The
result is the voltage profile of
the three phase voltages, as
shown in Fig. 3.
The phenomenon in
practice
A lighting installation can be
taken as an example for a
practical explanation of the
phenomenon of neutral point
displacement.
If the neutral conductor is not
connected in a "three-phase
installation", the result is both
overvoltage and undervoltage
at the consumers, i.e. the
electronic control gear units.
This means that the input voltage
at the ECG can theoretically
be between 0 V and 400 V.

Effects on the electronics
The power supply in Europe is
so stable that voltage fluctuations
in excess of 10% in
either direction are generally
not exceeded. Electronic
control gear from OSRAM is
engineered in such a way that
the probable fluctuations in
the line input voltage are
already taken into account in
the design.
PROFESSIONAL pays off
Operators of lighting installations
equipped with electronic
OSRAM control gear from the
Professional segment cannot
detect any difference in
brightness in this fluctuation
range of ± 10%. This ECG is
designed in such a way that,
on the lamp side, hardly any
fluctuations in the line input
voltage in the range from 207 V
to 254 V are transmitted. The
lamp output remains virtually
constant in this voltage range.

Line voltages in excess of
264 V either occur briefly in
the form of "voltage peaks",
or they are permanently
present as a result of faulty
installation in the three-phase
system.
With ECG from the Professional
segment, the input voltage
can even assume values of up
to 350 V for a defined period
of time. This has no effect on
the operation of the ECG.
In most cases, faulty installation
involves the neutral conductor
not being connected. This can,
for example, happen following
official acceptance of a largescale
installation by a test
institute, since the neutral
conductor has to be disconnected
for some tests.
Depending on where the
neutral point is displaced to
(Fig. 2), the applied input voltage
can also drop to below
200 V. QUICKTRONIC ECG
from the Professional segment
is likewise designed to cope
with this phenomenon.
However, regardless of the
ECG used, a fluorescent lamp
can only be ignited at above
198 V. In other words, reliable
"switching on" of the lighting
cannot be guaranteed below
this voltage value.
Experience acquired by
OSRAM in recent years has
shown that these product
characteristics of QUICK-
TRONIC control gear from the
Professional segment are
perfectly adequate (Table 1)
for preventing the ECG from
being damaged by overvoltage
or undervoltage.

Wireless freedom
Established solution
Touch DIM has nowadays
become a synonym for easyto-handle
light controls.
With Touch DIM, the mains
voltage is used directly as a
control signal via a commercially
available pushbutton,
meaning that the control unit
can be eliminated. This permits
extremely low-cost realisation
of dimmable lighting installations
that cater to many demands
on convenience.
Very convenient operation
With the new "Touch DIM
Remote Control System", all
Touch DIM-compatible electronic
control gear - identified
by the Touch DIM logo - such
as QTi DALI or
QT DALI from
OSRAM, can be
conveniently controlled
remotely. The system
consists of a 2-channel radio
receiver module and a 2-channel
radio control button.
The receiver module for controlling
up to 2 x 20 ECG units
can either be installed directly
in a luminaire, or fitted in a
false ceiling with a snap-on
mounting kit.
OSRAM ECG-SPOT 2/2004

Touch DIM and radio offer new possibilities
The system is totally maintenance-free.
For the first time,
no batteries are required for
supplying the transmitter
module in the radio control
button thanks to the use of
innovative piezoelectric technology.
In addition, due to its
extremely reliable transmission
over distances of up to roughly
30 m in buildings and 300 m
outdoors, the "Touch DIM
Remote Control System"
stands out as a truly professional
solution compared to
the host of products from the
consumer sector available on
the market.
Focus on retrofitting
The mains connection of the
luminaires is sufficient for use
of the Touch DIM receiver. As
a result, the modernisation of
existing lighting installations
no longer requires the installation
of new cables.
This also offers excellent conditions
for integration into
open architecture with glass
Fig. 1. The Touch DIM RC radio
receiver module is just 21 mm high
walls, or into historical buildings,
since the radio control
button does not require a
flush-mounted box and can
always be positioned optimally
or later relocated at any time
without major effort.
Options for flexible
expansion
The unique coding of each
control button prevents mutual
interference between adjacent
systems. Up to 30 radio control
buttons can very simply
be programmed into each
receiver module at the push of
a button, and deleted just as
simply if necessary. In addition,
the use of one radio control
button for several receivers
permits expansion, or
flexible grouping of several
areas of a room. Lighting control
can thus easily be adapted
to changing room conditions
and occupancies without
rewiring.
Touch DIM Remote Control
reduces the installation and
maintenance effort substantially.
In conjunction with the
Fig. 2. Touch DIM radio control button
new generation of intelligent
QTi control gear, it additionally
offers a hitherto unknown
degree of freedom when planning
and realising modern
lighting solutions.
The system is not only suitable
for use in functional buildings:
in combination with the new
HTi intelligent transformer for
the operation of low-voltage
halogen lamps, it also caters
to demanding applications in
the private residential sector.

Warm-white adds atmosphere
Conversion changes
atmosphere
From today's point of view, the
operation of mercury vapour
lamps is relatively uneconomical.
Compact fluorescent
lamps offer an alternative.
This fact was also recognised
by the Elektrizitätswerk
Tegernsee utility company.
They, and the communities
they serve, had long since
wanted to do away with the
HQL mercury vapour lamps
used in the past. The old
lamps have gradually been
replaced by compact fluorescent
lamps since mid-2003.
Optimised operation is guaranteed
by innovative control
gear from OSRAM. And because
of the different colour
temperature, the atmosphere
in urban spaces has also
changed.

600 lamp-post luminaires in

Consequently, at the request
of Elektrizitätswerk Tegernsee,
the LIC-Langmatz company
developed a low-cost, easyto-install
conversion kit for the
"EL-218 AMSTERDAM" and
"EL-77 BAVARIA" luminaires.
The kit consists of a base
plate, equipped with QUICK-
TRONIC QT-T/E 1x57/230-240
control gear, and a lamp
socket for DULUX T/E 57 IN
compact fluorescent lamps.
For conversion, only two
screws and a plug-and-socket

Powerful lamp for outdoor
lighting
Compact fluorescent lamps of
the IN range are amalgamtype
lamps eminently suitable
for use in outdoor lighting.
The amalgam they contain
guarantees a luminous flux of
more than 90% of the nominal
luminous flux in the temperature
range from +5 °C to
+70 °C.

Other advantages of the compact fluorescent lamp
The flexible choice of colour
temperature - 4,000 K, 3,000 K
or 2,700 K - offers an additional
benefit: the communities
now radiate warm-white light,
rather than neutral white
(Fig. 1).
The targeted savings on energy
costs arise from the substantially
higher system luminous
efficacy of the DULUX lamp
compared to the mercury
vapour lamp: 69 lm/W
instead of 43 lm/W. The higher
luminous flux of 4,300 lm, as
opposed to 3,800 lm, additionally
results in higher illuminance
values on roads and
footpaths.
Moreover, the lower thermal
load, together with roughly
only half as much UV emission,
protects the luminaire louvres
against premature ageing.
Control gear for reliable
ignition
The specially developed
QUICKTRONIC QT-T/E
1x57/230-240 electronic
control gear is optimally
suited to operation of the
DULUX T/E 57W IN amalgam
lamp. In addition to offering
all the benefits of electronic
operation, this ECG also
ensures reliable lamp ignition
at ambient temperatures down
to -20 °C.

Dimmer understands DALI
Electronic transformers, highvoltage
halogen lamps and
incandescent lamps can now
very easily be integrated in
DALI systems.
The HT DALI DIM compact
dimming unit is designed with
a cable clamp for independent
installation. In the unit, an
incoming DALI signal is converted
into a trailing edge phase
control signal, which can then
be used for controlling the
specified components.
The unit operates with a mains
voltage of 220 V to 240 V at
50/60 Hz. The maximum load
is 500 W, and the dimming
range extends from 0 to 100%.
This further expands the range
of DALI products from OSRAM,
opening up new applications:
entering the market with a
system - comprising control
components, sensors, operating
elements, converters,
DALI ECG and a dimming unit -
offers advantages not only for
the customer. The system
makes it possible to realise a
variety of lighting scenes conveniently
and easily - now also
using high-voltage halogen
lamps.
