Claus Regitz

Dear Reader,

Prompted not least by the Ecodesign Directive (EuP) and its regulations, energy

efficiency and sustainability have become the predominant topics in building

services engineering. This has speeded up the development of even better

products. Although quantum leaps have only been made in the context of

LEDs and their technical lighting properties, such as a luminous efficacy of

150 lm/W under laboratory conditions at OSRAM, there is also still considerable

potential slumbering in the established technologies. As a result, room for

improvement remains in terms of the energy efficiency and economy of lighting

systems, including simple installation, straightforward modification or extension

and long maintenance intervals. All further developments and improvements

by OSRAM focus on high benefit for the user.

Examples from the “conventional” sector include the XT versions of our

compact fluorescent lamps OSRAM DULUX L, which have a lamp life of

up to 36,000 hours, or the product families HCI-TT and ET replacing the

mercury vapour lamps. However, electronic control gear units such as the

POWERTRONIC PTo 3 DIM with multiple control functions also have

considerable potential.

Higher luminous efficacy is not the only topic of interest in the LED sector. The

LINEARlight Flex Protect range in Safety Class IP67 for illuminated advertising

uses a new encapsulation material promising greater transparency throughout

the entire life cycle. OSRAM now offers the easy to install LEDVANCE XL down-

lights to replace almost all recessed luminaires with two 26 W compact fluores-

cent lamps.

The range of light management products for indoor use is also changing, for

instance with the HIGH BAY motion sensor for use up to a height of 13 m.

When combined with daylight-dependent control, energy efficiency can be

boosted by up to 45%.

It is system solutions which yield the greatest benefit for users – a domain in

which OSRAM is seen as a competent partner offering a vast range of

products from its Professional Lighting Business Unit. In this way, all project-

specific tasks and requirements can be professionally solved true to our

philosophy of “Choice for the customer”.

This new issue of light sphere is also packed with interesting information

highlighting the system concept.

Yours,

Claus Regitz – Manager Professional Lighting Business Unit

OSRAM congratulates the festival with a unique light show

“Oktoberfest” celebrates 200 years

A dazzling celebration

Between 18th September and 4th October 2010, roughly 6.4 million people

from around the world came to the Theresienwiese in Munich. This year's

“Wiesn”, as it is fondly known, was a very special occasion marking the 200th

anniversary of the Oktoberfest. OSRAM and A&O Lighting Technology GmbH

presented the city of Munich with a superlative light show – instead of a cake

bearing 200 candles, as OSRAM's CEO Martin Goetzeler remarked. Every

evening between 1st and 4th October, hundreds of thousands of Oktoberfest

guests marvelled over a show more astounding than anything seen before:

modern lighting and projection technology bathed the Bavaria monument and

the night sky with a variety of light motifs. The “Ruhmeshalle” pantheon lit up

with atmospheric lighting effects. The base of the monument was also illumi-

nated with three Oktoberfest logos and congratulations.

To celebrate the 200th anniversary of the Oktoberfest, OSRAM and A&O Lighting presented the city of Munich with a superlative light show. High-power LEDs and light projectors bathed the Ruhmeshalle and Bavaria monument in atmospheric light, painting the night sky with a variety of light motifs.

Link to the future

More than 8,000 high-power LEDs

were used to create this magnificent

architectural illumination of the

Ruhmeshalle and Bavaria monument.

This is tomorrow's technology, for

OSRAM already generates more than

20% of its total sales with this technol-

ogy and less than 5% with classical

incandescent lamps. And so, the

show's LED light bridged the gap

between the long tradition of the

Oktoberfest and its future – which will

hopefully last for another 200 years.

Falcon light projectors – often found

at sports events and large (open air)

concerts – were also used. The

projectors were equipped with XBO

7,000 W and XStage 3,000 W short

arc xenon lamps from OSRAM which

feature an exceedingly high luminous

flux and good colour rendering prop-

erties.

A&O Lighting, one of the industry's

most successful firms located in Oyten

near Bremen, was responsible for

production and technical execution

of the light show.

There was a socially responsible

element to this project, too: OSRAM

ensured that, throughout the light

display, the spectacle illuminating

Munich's night sky had no impact

on the climate. The total energy con-

sumption, including that for transport

to and from the location as well as

installation and dismantling, was con-

verted into the savings which can be

made by using energy-saving lamps.

The figure was generously rounded up

to the equivalent of the savings made

with 200 energy-saving lamps and

OSRAM donated a corresponding

quantity of such lamps to the charity

“Münchner Tafel”.

By popular request

OSRAM has responded to users'

increasing demands by extending

the functionality of the new DALI

PROFESSIONAL light control system.

After all, DALI light control systems

are now proving their value every-

where, be it in office and conference

rooms, the hotel and restaurant trade

or in industrial environments, such as

high-bay warehouses. What's more,

the tasks required of dimmable

lighting solutions can focus on energy-

efficient operation, as well as on the

reproduction of defined lighting

scenes.

New applications with DALI PROFESSIONAL light control system

A new dimension in management

Fig. 1 The new DALI PROFESSIONAL light control system proves its potential for lighting solutions in office or conference rooms, as well as in the industrial sector.

DALI control units can be used not

only for all conventional lamps availa-

ble on the market, but also for LEDs,

thus creating the basis for made-to-

measure lighting solutions.

The requirements imposed on light

control systems have increased suc-

cessively with the establishment of the

DALI interface standard. In addition

to basic functions, such as daylight-

dependent control with occupancy

detection in offices or industry, there

is also a growing demand for use-

based light scenes in meeting and

conference rooms (Fig. 1). These

two capabilities can also be com-

bined, for example in multi-purpose

buildings, to accommodate different

events and different types of use.

Flexibility is another bonus

Flexibility is another factor underlying

the rapid spread of DALI technology.

When a room's use changes and

its layout is adapted accordingly, the

various light groups need only be

reprogrammed without having to

modify the wiring.

Since light groups can be flexibly

addressed by such DALI light control

systems, installation is greatly simplified

in relation to one based on 1 .... 10 V

technology. Besides which, standard

mains-compatible installation lines can

be used as a control line.

For higher demands

Sensor systems and operating

elements must increasingly be con-

nected to two-wire DALI control lines

in order to be able to upgrade existing

lighting solutions in a way that is a

less labour intensive task than when

laying additional wiring. This simpli-

fies the planning of such extensions,

too.

To meet these requirements,

OSRAM has developed the new DALI

PROFESSIONAL light control system

with sensors and operating elements,

such as push-buttons or touch panels,

which can be connected to the DALI

control line in addition to the DALI

luminaires.

Up to 64 freely addressable DALI

control units can be connected to

each of the four DALI outputs. Further

sensors or operating elements can

also be connected without having to

reduce the number of DALI control

units.

The potential in the four DALI lines of

the DALI PROFESSIONAL controller,

each of which has a control line up to

300 m long, is unrivalled, with a total

of 256 individually ad dressable ECG

units which can be broken down into

5

Fig. 2 With four DALI lines and the possibility of connecting sensors and operating elements, the DALI PROFESSIONAL light control system offers extensive flexibility and convenience for installation and planning.

as many as 64 light groups, as well

as up to 16 sensors via coupling mo-

dules and 32 push-button couplers,

each for four standard push-buttons

or switches (Fig. 2).

As of early 2011, it will even be possible

to connect maintenance-free radio

switches using EnOcean technology

directly to the DALI line via a special

receiver.

Diversity is the key

The DALI PROFESSIONAL light control

system opens up further areas of use

for DALI. The sensor systems can

be installed either in the luminaire or

as a standalone unit in a suspended

ceiling (Fig. 3). And the same diversity

also extends to the operating elements:

from simple push-buttons or main-

tenance-free EnOcean radio switches

and the design-oriented “Glass Touch”

user interface to a configurable Touch

Panel (Fig. 4).

The controller which lies at the heart

of the system features plug-and-play

functionality, meaning that simple

applications can be achieved without

reconfiguring the DALI system. In this

way, all DALI luminaires which are

already connected to a DALI output

can be switched via an occupancy

detector connected to the same DALI

line, or they can be manually switched

or dimmed via push-buttons.

Correct functioning of both the instal-

lation and the connected DALI lumi-

naires can be checked by means of

two buttons on the controller; an LED

indicator makes diagnosis easy.

The structured configuration software

ensures that functionality and light

groups can be individually adapted

in line with project requirements via

clearly structured work steps.

The DALI PROFESSIONAL light control

system offers an array of capabilities

benefiting luminaire manufacturers,

as well as ambitious electrical fitters

or planners and light planners. DALI

PROFESSIONAL ensures considerable

value-added, whether it serves a basis

for dynamic lighting solutions geared

to energy efficiency, for atmospheric

light scenes or whether it caters to

both these aspects at once.

New awareness

Terminal T3 at Delhi Indira Gandhi International Airport is the most ambitious

infrastructure project undertaken to date in India and symbolic of the country's

booming economy. The glass and steel construction was officially inaugurated

by India's Prime Minister Manmohan Singh at the beginning of July 2010 –

well before the XIXth Commonwealth Games started on 3rd October 2010.

The terminal is designed to handle roughly 34 million passengers per year.

The new terminal building will be one of the largest in the world: with an area

of 500,000 m² it ranks 6th behind such terminals as Peking with 900,000 m²,

Madrid with 757,000 m² or Bangkok with 563,000 m². A total of 48 directly

adjacent and nine remote aircraft parking bays, 78 passenger boarding

bridges and 168 check-in desks will ensure that passengers are handled in

less than 45 minutes.

The new terminal T3 was built in a record-breaking time of 37 months by

40,000 workers at a cost of roughly 2 billion euros.

Long-term

The airport's development, manage-

ment and operation are in the hands

of Delhi International Airport pte. Ltd.

(DIAL), a joint venture between the GMR

Group with a 54% holding, Fraport

and Eraman Malaysia, as well as the

state-owned Airports of India with a

blocking minority of 26%. The licence

runs for 30 years with optional renewal

for another 30 years. On account of

its extensive experience, Fraport AG

is responsible for the air port's trouble-

free operation, while Eraman Malaysia

acts as retail consultant.

OSRAM India was awarded the con-

tract for delivery of lamps and control

gear by the Debbas Group with head-

quarters in Beirut, Lebanon, which

had been commissioned by GMR to

handle the entire architectural lighting.

For OSRAM, this is the largest project

worldwide involving HO CONSTANT T5

fluorescent lamps. In addition to the

lighting for the terminal building itself,

however, the overall contract also en-

compassed illumination of the runway

– which can even accommodate the

Airbus A380 – with 45 W and 200 W

halogen lamps, as well as equipping

the offices with 70,000 T5 fluorescent

lamps.

Exceedingly bright and efficient

The building with its colourful facade

facing the runway and decorated

with huge Buddha hands above the

check-in desks was designed by the

British architects Mott MacDonald

(Fig. 1). A glass roof mounted on

white pillars ensures that the building

is flooded with sufficient daylight while

at the same time reflecting the sun's

heat. In this way, the energy required

for lighting and air-conditioning has

been reduced.

Positive features count

During the hours of darkness, 67,000

HO CONSTANT 54 W and 24 W T5

fluorescent lamps controlled by

34,000 dimmable QUICKTRONIC

INTELLIGENT electronic control gear

units and 16,000 QUICKTRONIC

PROFESSIONAL units ensure a

bright, friendly interior atmosphere.

They are supplemented by more than

9,000 compact fluorescent lamps

and metal-halide lamps.

Excellent efficiency is assured above

all by the system of HO CONSTANT

T5 lamps and QUICKTRONIC

INTELLIGENT (Fig. 2).

This ensures a luminous flux of 90% in

the temperature range between 0 °C

and +70 °C, while luminaire efficiency

is improved by more than 10% by the

T5 CONSTANT technology (Fig. 3).

Fig. 3 The comparison highlights the excellent luminous flux behaviour of the HO CONSTANT T5 lamps.

Experience brings value-added

Integrated into a daylight-controlled

lighting installation, the dimmable

QTi 2x28/54 DIM ECG units can boost

energy efficiency enormously – in re-

lation to static installations – by more

than 30%, reducing both CO2 emis-

sions and costs at the same time.

The multi-stage System+Guarantee

from OSRAM covering the combination

of HO CONSTANT T5 lamps and

QUICKTRONIC INTELLIGENT naturally

also generates value-added.

The very first ECG to fail is replaced,

without waiting for the specified ECG

failure rate to be exceeded. In other

words, OSRAM consistently stands

for high quality.

For DIAL, however, ecological com-

patibility is important not only when

it comes to lighting, but also with

regard to the landscaping around

terminal T3: more than 920,000 trees

and plants, including a selection of

exotic orchids, have been planted

around the terminal complex.

Terminal T3 concludes the first phase

of expansion at Indira Gandhi Airport,

which is ultimately destined to handle

up to 100 million passengers per year.

Future-oriented training for electrical fitters

Lighting control enters the training curriculum

Tailored to specific tasks

Lighting control systems are becoming steadily more

important for two main reasons. For one thing, both rising

energy prices and statutory regulations to improve the

energy efficiency of buildings are having an impact on the

design of lighting solutions. Potential energy savings can

be tapped here with the aid of lighting control units with

occupancy detectors and daylight-dependent control. The

DALI interface standard paves the way for concepts which

are both simple and functional, and in which light groups

can be flexibly configured on the basis of individually

addressable DALI control units.

The other reason is that LED technology is becoming

increasingly important as a basis for RGB colour mixing

or for applications using white light with variable colour

temperature. Lighting control is essential here.

At the same time, there is a growing awareness of the

fact that lighting control must be included in the training

curriculum (Fig. 1). This applies primarily to electronic

engineers specialising in energy and buildings (EFEG),

electronic engineers for building services (EBT), electronic

engineers for buildings and infrastructure systems (EGI)

and event technicians.

This has prompted OSRAM and ELABO TrainingsSysteme

GmbH, a leader in the didactic training systems market

for basic and advanced industrial and technical training,

to discuss ways of translating the subject of lighting

control into suitable training material and to consider

which lighting components would offer the best support

to this end.

Based in Kindingen, the company offers a large range of

practical training solutions for electrical engineers in the

fields of automation / control technology, as well as instal-

lation and building services management. Rainer Wrenger

from the department of Marketing Development Light

Management Systems at OSRAM discussed the subject of

lighting control with the head of development at ELABO TS,

Johann Hausner.

OSRAM: Mr. Hausner, the profession

of electrical fitter is changing. How

are you adjusting to this development?

ELABO TS: We are keeping an eye

on the industrial market environment

so that those trends which become

established in the long term can be

spotted early on. These subjects are

then incorporated into our training

concepts and hardware systems

developed to implement these future

technologies in the reality of everyday

training. The didactic complement

is provided by practically oriented

manuals ensuring the competent

transfer of knowledge.

OSRAM: Which points do you focus

on when designing training systems?

ELABO TS: One point of importance

is for the training system to clearly

and comprehensively reflect the

structure of the technology. All char-

acteristic features are presented to the

trainees in the best possible quality

and with a clear practical relevance.

Everyday competence is reinforced

by the didactic structure of the train-

ing system. We achieve this through

the appropriate choice and optimum

arrangement of real industrial compo-

nents.

OSRAM: How important do you

consider lighting control to be for

electrical fitters?

ELABO TS: Lighting control will

become more important for two rea-

sons, namely energy efficiency and

convenience. Both are decisive criteria

for the user. For the electrical fitter,

attention focuses on simple and

correct installation. It should also be

possible to configure the functionality

individually in each case.

OSRAM: How do you view the DALI

standard in this context?

ELABO TS: Electrical fitters' knowl-

edge of DALI differs considerably,

especially as regards the simpler

installation and improved capabilities

in comparison to 1…10 V technology

– this makes it all the more important

to convey this information during the

Fig. 1 Lighting control is gaining in importance in the training of electrical fitters.

training stage and to prepare young

professionals for these technologies

(Fig. 2).

The Touch DIM interface of DALI

electronic control gear provides an

easy introduction. In a next phase,

the individual control units can be

operated via DALI without conversion.

OSRAM: How important are LED

solutions and which know-how is

needed?

ELABO TS: Trainees must be intro-

duced to the possibilities offered

by LED technology. Many firms are

lacking in this respect. We consider

it important for training systems to

draw attention to the fundamentals

and the basic principles underlying

control systems, as well as to their

potential, and to provide tips for

installation.

OSRAM: How much do experienced

electrical fitters know about LED

technology?

ELABO TS: LED technology is asso-

ciated with saving energy, better

luminous efficacy or higher efficiency.

Their knowledge of the variety of

applications, LED control, operating

conditions and installation varies con-

siderably. This makes it all the more

important to include the principles of

LED technology during the training

phase and to highlight the differences

between this technology and conven-

tional lighting control systems.

OSRAM: In this context, how do

you see the principles of and the

possibilities offered by the EASY Color

Control light control system – an option

which can be used, among other

things, for LED applications?

ELABO TS: As it is a modular system

with easily installed components, it

will be of interest to all “electrical fitters”

(Fig. 3). EASY Color Control can be

used for projects large or small. As

a result, the various modules can

be used in the training system either

individually or in combination.

OSRAM: Mr. Hausner, thank you for

this interesting conversation. We wish

you all the best with your training

concept for lighting control systems.

More and more popular

Lighting installations with DALI light

control are versatile systems ranging

from applications with simple manual

dimming of a small number of lumi-

naires to networked solutions with

numerous luminaires linked to the

building management system via

gateways. This makes DALI equally

suitable for both individual offices and

large open-plan offices in which a

flexible layout is part of the everyday

life (Fig. 1). Dimmable luminaires with

DALI control units for all standard

lamps are now commonplace.

To date, most of the simple dimming

solutions are based on the Touch

DIM principle, the mains voltage at

the DALI input being adjusted as

required via a standard push-button.

DALI repeater: extension component for universal use

Touch DIM broadens its horizonsHowever, this convenient system is

coming up against its technical limita-

tions: six DALI control units with a total

cable length of 25 m represent the

maximum possible. Due to the under-

lying principle, synchronisation may

be lost between the individual control

units if they are more numerous or

in the event of poor mains quality

with harmonics. One possible con-

sequence is that individual luminaires

cannot be dimmed or switched in the

group.

Intelligent solution

OSRAM recommends the use of

its DALI repeater for small or larger

Touch DIM applications. With the

DALI repeater, up to 64 DALI units

can be dimmed in one group with a

single push-button input – even with

a cable length of up to 300 m (Fig. 2).

If this proves insufficient, several

repeaters can be cascaded to form a

larger system of any desired size and

the connected DALI luminaires dimmed

as a group (Fig. 3).

Synchronisation no longer poses a

prob lem, as only one DALI signal is

sent to the ECG units on the output

side.

New freedom

Alternatively, the DALI repeater can

also be combined with a radio receiver

using EnOcean technology. Featuring

battery and maintenance-free technol-

ogy, EnOcean radio switches are ex-

tremely flexible, as they can be simply

affixed to glass surfaces or partitions.

Fig. 1 The range of DALI-based lighting installations extends from simple manual dimming to networked solutions with manifold requirements.

Touch DIM broadens its horizonsIn lighting solutions with DALI control

units, such as DALI PROFESSIONAL

from OSRAM, or DALI gateways for

linking to the building management

system, the DALI repeater also makes

it possible to increase the number

of controllable DALI control units. In

such a system, the DALI repeater

acts as a connected DALI ECG, the

control units on the repeater's output

side operating as a single light group.

Versions for all requirements

The DALI repeater is available both

as a flat 21 mm housing for installation

in the luminaire and as a rail version

with integrated relay contact for in-

stallation as a standalone unit (Fig. 4).

This contact can be used to discon-

nect the supply voltage and thus

eliminate stand-by losses inside the

unit when the lamps are off. The

inrush current of the connected DALI

control units must naturally be taken

into account here – the maximum

number of devices per switch contact

is specified for the various types in

the repeater data sheet.

These two versions of the DALI

repeater from OSRAM offer much

more scope when expanding DALI-

based lighting solutions. This yields

major advantages for planning and

installation which will benefit not just

luminaire manufacturers, but planners

and electrical fitters, too.

Homely atmosphere

Idyllically set in park grounds and just a stone's throw from

Hamburg's city centre and the Alster lake, the privately

run Grand Elysée hotel attracts guests with its family

atmosphere. Every last detail in the hotel bears the stamp

of its founder Eugen Block. High-quality materials, warm

colours and exquisite design make for unique 5-Star luxury.

It is therefore no surprise to find that the Grand Elysée won

the Conga Award 2009 as Germany's best conference

hotel. A total of 511 spacious rooms and elegant suites

ensure that the hotel's guests feel thoroughly at ease. The

hotel's vibrant centrepiece is the “Boulevard”, the place to

meet, with boutiques and six restaurants with first-class

international cuisine.

The Grand Elysée is also a sought-after venue: 25 rooms of

all sizes equipped with the latest technology accommodate

conferences, seminars and festive events for anything from

two to 1,200 people – and always with a perfect setting.

Ready for the future

The hotel celebrates its 25th anniversary in 2010 –

reason enough for a thorough renovation. In the large

“Hall of Mirrors”, for example, the Hamburg firm göpotec

Gesellschaft für Licht- und Elektrotechnik mbH has

converted the six crystal chandeliers to innovative LED

technology from OSRAM (Fig. 1). Now, LINEARlight

Colormix Flex LED modules have replaced the 360 40 W

incandescent lamps which will be banned throughout

Europe from 2012 onwards. Controlled by OPTOTRONIC

OT75 and OT DMX RGB DIM control units, the Hall of

Mirrors will in future shine not only in white, but also in

every conceivable shade thanks to RGB colour mixing

Fig. 1 The six crystal chandeliers in the large Hall of Mirrors now light up with LED technology from OSRAM.

– always precisely tailored to the occasion and the specific

requirements, such as the Corporate Design of a corporate

event.

And the result is illuminating in every respect. Fitting the

chandeliers with LEDs reduces energy consumption by

36,000 kWh per year – the investment consequently pays

off in just nine months. This innovative solution in the Hall

of Mirrors is rounded off by 20 LEDVANCE Downlight L

luminaires from OSRAM. The energy-efficient luminaire

with OSLON LED is unobtrusively designed with an opaque

diffuser. Due to its outstanding system efficiency and

excellent technical properties, the LEDVANCE Downlight L

replaces conventional versions with compact 26 W com-

pact fluo rescent lamp or 75 W low-voltage halogen lamp.

The oval reigns supreme

LINEARlight DRAGON Colormix LED modules similarly

create a fitting mood when used as the backlit "eye" in the

middle of the ceiling in the “Oval Office” (Fig. 2). Their po-

tential for saving energy is also impressively demonstrated

in the multi-functional sixth-floor Board Room with its

panoramic view across the roofs of Hamburg. Controlled

by OPTOTRONIC control units and OT DMX RGB DIM

dimmers, the modules create stunning coloured light scenes

with exceedingly homogeneous illumination. What's more,

energy efficiency has been boosted by 42% in comparison

to the previous lighting solution.

A glowing reception

The transforming effect of LED light is not only shown in-

side: the newly built canopy roof outside the “Large Foyer”

– the reception area leading to the festive hall – also catches

the eye with a spectacular presentation of coloured light

for events. The glass ceiling backlit by DRAGONchain

Colormix LED modules appears exceedingly homogeneous

(Fig. 3). Now, the players of the football club “Hamburger

SV” can be fittingly welcomed as regular guests in their

traditional blue colour.

The advantages of LED lighting from OSRAM, especially

its energy efficiency and the long service life with reduced

maintenance, were so obvious that the innovative semi-

conductor lighting has now been installed in many areas,

including the en-suite bathrooms, the cove lighting near

the elevators and the display cases. The Grand Elysée

has become a reference project demonstrating the variety

of possible LED applications.

Efficiency with distinction

Energy efficiency is the predominant

topic in all project considerations,

building analyses and lighting con-

cepts. The new OSRAM DULUX L HE

lamp family consequently attracted

considerable interest very soon after

being introduced on the market

(Fig. 1). With a luminous efficacy

of up to 100 lm/W at an operating

temperature of 35 °C, these lamps

offer considerable value-added for

lighting solutions in offices, hotels

and public facilities, for their con-

nected load can be significantly

Efficiency and excellencereduced without diminishing their

brightness.

The most common areas of use are

covered by wattages of 16 W, 22 W,

26 W and 28 W with a luminous flux

ranging from 1,600 lm to 2,800 lm.

The OSRAM DULUX L HE family with

a mean lamp life of 20,000 hours

includes versions with a colour tem-

perature of 3,000 K and 4,000 K.

Combining these lamps with standard

QUICKTRONIC PROFESSIONAL QTP5

or QUICKTRONIC INTELLIGENT QTi

electronic control gear or dimmable

QTi (DALI) ... DIM ECG units results in

exceedingly energy-efficient systems

which can be dimmed to 3% of lumi-

nous flux.

The better alternative

With these properties, the OSRAM

DULUX L HE compact fluorescent

lamps are ideal, for example, for use

in standard luminaires which offer

both outstanding energy efficiency

and excellent light quality. Lamping

with 4 x OSRAM DULUX L HE 28 W

or 4 x OSRAM DULUX L HE 26 W as

an energy-efficient alternative to the

standard OSRAM DULUX L 4 x 55 W

compact lamps reduces the connec t-

ed load by roughly 50% (Table 1).

Besides which, luminaire efficiency

can be boosted from 80% to over

90%. Incorrect lamping is prevented

by the slightly modified 2GX11 base

and socket system (Fig. 2).

Having recognised the advantages

of these energy-efficient OSRAM

DULUX L HE compact fluorescent

lamps, a number of luminaire manu-

facturers have responded by designing

their luminaires to operate with them,

prime examples being the standard

luminaires ECO from Neuco and

CAPA from Zumtobel (Fig. 3). The

latter stands out through its luminaire

efficiency of over 95% combined with

a high proportion of direct light and

consistent reduction of luminance,

resulting in a luminous flux of almost

85 lm/W for the luminaire.

Advantageous on the ceiling

OSRAM DULUX L HE compact fluo-

rescent lamps also demonstrate their

advantages when fitted in square

flush-mounted ceiling luminaires. Their

good performance is highlighted by a

comparison of systems with T8 and

T5 lamps in louver luminaires (Table 2).

The luminaires' higher luminous flux

and energy efficiency yields a variety

of benefits. Maintenance costs are

also reduced, as only two lamps are

needed instead of four.

With their energy efficiency and lamp

life, OSRAM DULUX L HE compact

fluorescent lamps are good news

in large-size design luminaires, too

(Fig. 4), such as those in long-duty

use in hotels and public facilities.

Together with ECG units from OSRAM,

the new OSRAM DULUX L HE lamp

family represents the cutting edge,

being exceedingly energy-efficient.

What's more, systems comprising

the OSRAM DULUX L HE compact

fluorescent lamps and OSRAM ECG

are covered by the proven 5-year

System+ guarantee. And when these

two components are combined with

LMS control units from OSRAM, the

new so-called Premium guarantee

from OSRAM comes into play, yielding

additional benefits for the user.

Concentrated competence for more efficiencyConcentrated competence for more efficiencySiemens and OSRAM join forces on the “Building KnowLEDge” tour

Focus on the futureEnergy efficiency and sustainability have become the predominant topics in building services engineering. The application-based light and building services management of the future is considered the key to meeting the stringent criteria imposed on energy efficiency for “Green Buildings” and low-energy buildings. Intelligent management is based on innovative products, systems and services, as well as highly efficient complete solutions. Today, quantum leaps are being achieved above all in the relatively “young” fields of LED and OLED technology. What's more, there are many ways to meet the needs of climate and environmental protection while simultaneously cutting operating costs and boosting cost-efficiency.

fluorescent lamps or 75 W low-voltage

halogen lamps will also be presented.

Ideal conditions are created for

optimising the functionality, energy

efficiency, light quality and conveni-

ence of each application when they

are linked via the intelligent DALI

MULTIeco light control system from

OSRAM.

Siemens' know-how in the field of

“Building Technologies” provides the

framework for perfectly harmonising

the various subsections.

This interaction forms the basis for

energy-efficient, versatile and creative

solutions generating a high user

benefit. Particular attention will also

be paid to room automation, energy

monitoring, e-car charging stations

and photovoltaic systems.

The fascination of efficiency

The nine events of the “Building

KnowLEDge 2011” tour in Germany

(Fig. 2) and the 13 in the rest of

Europe will impressively demonstrate

how ambitious goals in terms of

energy efficiency and sustainability

can be achieved with innovative

technologies.

Papers by knowledgeable Siemens

and OSRAM employees will present

comprehensive information on

services.

These topics can subsequently be

discussed in depth to boost personal

competence in solving the manifold

requirements encountered in shops,

offices and the hospitality sector. For

added benefit, experts from the two

companies' light, building automation

and energy distribution divisions will

provide intensive advice and support

encompassing all subsections.

The presented opportunities offered by

innovative technologies from Siemens

Inspiration

The Europe-wide tour "Building

KnowLEDge 2011" (Fig. 1) provides

true inspiration for future-oriented

complete solutions in light and buil-

ding services management. Siemens

and OSRAM – two technically pro-

gressive companies with a long

tradition – have joined forces to draw

attention to the potential of modern

products and systems.

In 13 European countries and 22 cities,

electrical fitters, electrical and light

planners, wholesalers and architects

can talk with competent partners and

discover more about a new generation

of light and building services tech-

nology. Events are planned for the

following locations in Germany:

Munich, Mainz, Stuttgart, Cologne,

Hamburg, Bochum, Berlin, Dresden

and Hanover.

Structured variety

Each event in the “Building Know-

LEDge 2011” tour consists of three

components: an interesting exhibition,

an information forum with presenta-

tions on the latest technologies and

a spectacular LED cube.

Shops, offices and the hospitality

sector have been chosen as focal

areas from the large range of appli-

cations covered by Siemens and

OSRAM. Innovative lighting solutions

in the field of building automation and

energy distribution will be presented

live to illustrate typical tasks in these

domains. Different OSRAM LED mod-

ules, such as LINEARlight Colormix

Flex or LINEARlight DRAGON Slim,

display their potential in combination

Successful miniaturisation

The potential inherent in metal-halide

lamps is revealed wherever brilliant

light with very good colour rendering

is called for. Over the years, these

lamps have become ever smaller and

more powerful with the development

of new burner technologies. Another

step towards further miniaturisation

was taken when the POWERBALL

HCI-TX/P was presented at

Light+Building 2010.

The POWERBALL HCI-TX/P metal-

halide lamp from OSRAM – the

smallest shatterproof HID lamp

for use in open luminaires - has a

round ceramic burner and a new

base-and-socket system, the GU8.5

Twist & Lock (Fig. 1). With a maxi-

mum length of 98 mm including the

contact pins and a diameter of just

22 mm, the HCI-TX/P is unrivalled.

POWERBALL HCI-TX/P from OSRAM displays potential

Small in size, bright in light!Despite its compact size and

additional protective bulb, the lamp

delivers a very high luminous flux of

3,300 lm at 35 W and 7,300 lm at

70 W. As a result, this miniaturised

lamp achieves a luminous efficacy

of up to 100 lm/W.

The metal-halide lamp is designed

for use with electronic control gear

and operates most efficiently with

the matching POWERTRONIC unit

from OSRAM. Its average lamp life

of 12,000 hours makes for longer

intervals between lamp changes and

reduces maintenance work, which

ultimately also cuts operating costs.

Fig. 1 The shatterproof POWERBALL HCI-TX/P metal-halide lamp for use in open luminaires is not only unrivalled as regards its degree of miniaturisation, but also when it comes to lamp changes.

Fig. 3 The "Audi Urban Future Award 2010" in Venice was brilliantly illuminated by POWERBALL HCI-TX/P metal-halide lamps (photo: Sabine Reitmaier).

Small in size, bright in light!Greater freedom through

easy handling

Since the POWERBALL HCI-TX/P

lamp is approved for open luminaires,

a cover glass is not required. This

results in simpler and more cost-

effective luminaire designs as com-

pared to other technologies, ultimately

permitting more attractively priced

lighting systems.

The GU8.5-Twist & Lock system –

whose standardisation is currently

proceeding at the International

Electrotechnical Committee (IEC) –

is set to make life even easier. The

principle underlying the system has

already been used in the GU6.5 base

of the POWERBALL HCI-TF metal-

halide lamp for closed luminaires and

not only makes it easier for everyday

users to replace lamps, but also to

clean the luminaire. And that saves

both time and money.

The GU8.5 base is robust and the

socket ensures that the lamp is

locked securely. As a result, the lamp

is firmly secured and the pins reliably

make contact. In other words, the

lamp is precisely positioned in the

reflector to ensure optimum light

distribution.

Quick and easy lamp changes open

up new possibilities in terms of

handling. For the light colour can be

adapted in line with the time of year

or fashion trends, practically in a few

swift moves. The metal-halide lamps

are available in two light colours:

warm white with 3,000 K and neutral

white with 4,200 K and an excellent

colour rendering index of 93 and 96,

respectively. Brilliant presentation of

the user's goods is assured.

Brilliance is called for

POWERBALL HCI-TX/P metal-halide

lamps create brilliant highlights, above

all in decorative open downlights and

spots. They can be used for a whole

variety of purposes: in boutiques and

department stores, as well as in office

buildings, showrooms or exhibition

stands. Being shatterproof means

increased safety, the POWERBALL

HCI-TX/P can also be used for high-

quality lighting in hotels and restau-

rants where open luminaires are not

uncommon. The reinforced UV filter

protects colours and materials more

effectively than a conventional lumi-

naire with simple cover glass.

From 27th August to 26th September

2010, the POWERBALL HCI-TX/P

metal-halide lamp showed its brilliant

qualities at the exhibition “Audi Urban

Future Award 2010” in Venice (Fig. 2),

at which the award was also presen-

ted. The aim of the Award is provide

a look to the future and encourage

debate over the interaction between

mobility, architecture and urban de-

velopment.

In the lighting concept developed

by the Berlin engineering office

Kardorff Ingenieure Lichtplanung, the

open luminaires built by Interferenz

Lichtsysteme GmbH in Tönisvorst

were seemlessly integrated into the

walls of the pavilion. Reflected by

mirrors, the POWERBALL HCI-TX/P

lamp presented the exhibits of the six

internationally renowned architectural

offices in brilliant light with very good

colour rendering at one of its first

public appearances (Fig. 3). The stray

light was used to illuminate the ceiling.

News in brief

From the very beginning, the family of QUICKTRONIC PROFESSIONAL QTP5

electronic control gear units was the first choice for many users, as demonstrated

by the usage in a large number of projects with very different fields of application.

The second QTP5 generation introduced just over a year ago has followed in the

same footsteps. This successful family is now supplemented by QTP5 3x14 and

4x14 for three and four-lamp operation of LUMILUX HE 14 W T5 fluorescent lamps.

The properties of these ECG have been considerably improved to create even

greater freedom.

The most important feature of the QTP5 is its service life of 100,000 hours with a

maximum failure rate of 10% at tc = 65 °C. The shorter housing means that series-

connected emergency lighting modules can also be accommodated. More rapid

switching from AC power to DC power also makes them significantly more suitable

for emergency lighting systems.

Almost all applications can be covered in combination with LUMILUX CONSTANT, XT,

ES or Natura T5 lamps. The possibilities range from car parks, warehouses or cold

stores where very high or very low temperatures are encountered and extremely long

maintenance intervals are required, through to cost-effective and energy-efficient

lighting of large areas, such as supermarkets and open-plan offices. With the pos-

sibility of combining suitable sensor systems and industrial use with luminaires of

Safety Class II. Until recently, the latter applications in particular, i.e. those without

any earthing whatsoever, were the domain of conventional control gear or special-

purpose products and therefore very expensive ECG units. Thanks to the conside-

rably better EMC properties, the standard QTP5 ECG units are now also ideal for

use in single and two-lamp luminaires of Safety Class II.

The QUICKTRONIC PROFESSIONAL QTP5 certainly deserves to win a prize for

its versatility. These electronic control gear units are not only an ideal partner for

T5 lamps, but also for the new energy-efficient OSRAM DULUX L HE compact

fluorescent lamps - see page 14 of this edition of light sphere.

Whether for peaches or for car body parts: the QTP5 ECG unit from OSRAM is always an ideal choice in combination with LUMILUX T5 lamps.
