Editorial
On the current political scene the topic of integration
frequently crops up as a central issue to be addressed: be it
the integration of controversial ways of thinking, of cultural backgrounds or differing demands. This also applies to
future lighting solutions.
In the interplay of all building trades light is set to become
an integral part of architecture. We consider it our task to
put architecture centre stage.
For people with a strong visual focus both the technological and the optical integration of illumination is a key
quality criterion. Only when the latter is achieved does a
coherent whole emerge.
Let me invite you to come with us on a journey – a journey
where we integrate light into the buildings of today and
the buildings of the future, as your partner for individual
lighting solutions.
This feat, however, can only be achieved jointly.
As leading specialists for individual lighting solutions
WILA therefore maintains a close dialogue with all professions involved in building development and light planning.
Our integral light technology
puts individual architecture
centre stage.

Interview
“Quality of Interiors =
Interior Design Concept + Light Concept”
Ralf Schoofs, Interior Designer, Light Planner and Owner of Rhein Licht
on the rising demands, areas of tension, milestones and the digital future
of lighting design.
As a child what did you want to be when you grew up?
A vet or an interior designer.
How were you introduced to the lighting theme?
In my first project after completing my interior design
studies I planned the interior design for the board rooms
at Dresdner Bank Düsseldorf. Back then I met the light
planner Johannes Dinnebier. After joining his company
I was very lucky because I was allowed to develop and
devise the light planning scheme for these spaces and those
boardrooms designed and planned by my university
professor Prof. Ellen Birkelbach.
Comparing this first project with your current ones,
what has changed in your way of working?
A lot in terms of actual method: we used to present our
concepts with free-hand sketches produced with the help of
T-squares and the like. In terms of technology, especially in
view of controlling illumination systems – as we all know
– things have changed enormously. And in terms of content
light planning has moved away from the extraordinary,
almost ‘Messianic’ project specificity of the past towards an
integral specialist planner’s trade.
4
You established the Rhein Licht office for light planning
14 years ago. Every office has its own, inimitable design
signature. How would you describe your signature and/
or philosophy ?
My fellow student and business partner Thomas Dreist and I
established the office together back then. We had worked on
interior design projects and it seemed a logical conclusion
for us as interior designers to also deliver the light concepts
for those interior designs. Today, each one of our projects
is processed by fully trained interior designers. Maybe this
is our signature style and philosophy: we approach each
task and each room with an interior designer’s interest and
perspective, and everything always starts with an initial
free-hand sketch.
Considering today’s tight budgets – what about the
artistic ambition?
Light planning/ architectural lighting is first and foremost
a technical rather than an artistic discipline. If you are
alluding to our ambitions, then our ambition to favourably
complement rooms with meaningful illumination – inferred
from the interior concept – is articulated in every task. >
5WILA
Interview
“Illumination never is
a panacea for architectural
concepts of a questionable
quality.”
What is Lighting Design able to do in conjunction with
architecture – and where are the limits here?
Architectural lighting is never “accessorising” i.e. a
cosmetic panacea for architectural concepts of question­able
quality. As a rule, lighting should always serve and
complement the room concept, the architect’s design
intention and the specified fitness for purpose.
When realising projects the building owner and the
architect are very influential. Does cooperation in
projects like this always run smoothly?
Every collaborative project and project constellation is
different, as are the interests of the parties involved. Add
to this the constant impact of cost and time factors. Situations with conflicting interests like this always give rise to
tensions that can produce both constructive and destructive
effects. What counts in the end is that all stakeholders pull
together “in the light” of their jointly aspired results.

Everyone is talking about LEDs as a driving force in
technology. To your mind, what have been the three
most important innovations in the lighting field over
the past few years and what options do they open up for
your projects now?
LED technology and its use in architectural lighting is
definitely at the cutting edge of current developments.
A major milestone here was and still is the development of
electronic ballasts that can be dynamically controlled for
fluorescent lamp systems. These ballasts make it possible
to vary artificial light in offices, for instance, in conjunction
with daylight making it extremely efficient in energy terms.
The incorporation of lighting systems into electronic BUS
systems for building technology has given rise to very new
requirements and possibilities in the integral planning of
architectural lighting.
Looking ahead to the future – how will public buildings
be illuminated in ten years from now?
Entirely digitally! Since the inroads LED systems have made
in architectural lighting (if not before) and since the use of
digital BUS systems in the stricter sense we have seen a
digitalisation of illumination. This means that illumination
will in future be controlled by PCs from our workplace. Movement sensors will monitor the use of rooms and control the
illumination of access zones, while the colour temperature of
light sources will be dynamically changed during the day in
line with sunlight bringing it into line with our bio-rhythms.
In the reception areas illumination will be controlled inter­
actively by means of media technology and, finally, buildings
will become “information carriers” for their users. >
Fotos Thomas Solecki, Bochum
In addition to complying with all relevant standards,
light also plays an ever greater role in giving buildings
an individual look. Museums attract throngs of visitors
with their architecture. How important is lighting design
when planning new buildings today?
The relevance of lighting concepts is increasing all the
time. The functional requirements made on the illumination
of commercial or industrial facilities and buildings have
become ever more complex, especially in terms of energy
efficiency. Furthermore, it has now also been understood
that artificial light is a comparably inexpensive tool to
convey contents.
The Future of Architectural
Lighting is All Digital.
7WILA
Interview
Illumination will become interactive and digital.
Wouldn’t it be important, especially from a design point
of view, to combine light with other building functions –
after all, both are installed at very much the same stage
of finishing?
This is already occurring to a limited extent – for instance, in
the combination of “air-return luminaires”. Bringing different
trades and their different dimensional tolerances together
that precisely in a building, however, can cause problems in
project execution and drive up costs and working time.
As ambitious light planners we are torn between the two.
In 2004 our office gained the first “China experience” –
we had a job in Shanghai. You can’t be a Lighting Designer
if you are not immediately fascinated by this city’s skyline
by night. But it is precisely this city that also reveals the
questionability of this “orgy of light” – on a hot summer’s
day energy demands are so high that the illumination of
buildings is occasionally switched off entirely. Moreover,
the inflationary use of monochrome artificial light in our
latitudes often borders on the decorative and only enjoys
a very limited “validity”.
You often hear that architects want to have the light in a
project but don’t want to see any luminaires. Visual integration into the ceiling or architectural structures can
reduce design visibility to a minimum. How important
is luminaire design for you or should only the quality of
light matter – in line with that classic Bauhaus principle
“form follows function”?
This depends entirely on the brief of the project. For technical illumination systems photometric quality and efficiency
are decisive. Needless to say, the proportions and the details
of reflector and edge detailing always have to be discussed
and weighed up in each case.
Resources are becoming increasing scarce on a global
scale and costs are also rising. The standard currently
provides for 500 lx at workplaces. Won’t we soon have
to ask ourselves how much light we will still be able to
afford?
This is always a hot topic at our office and we can offer two
global views as answers here – as a free interpretation of the
economic principle:
What do you think luminaire manufacturers should
specifically develop for you in future?
Effective, very high-quality, durable and inexpensive
systems.
Planning in major projects is becoming more and more
complex. Is complexity still manageable and does this
also hold true for illumination planning?
The illumination of buildings is a relatively small trade
in comparison with the other trades and it is completely
manageable.
Many projects have a “stand-alone” nocturnal design.
Where in the past you simply used to switch off the light,
nowadays buildings are illuminated all night long. Isn’t
this a contradiction in terms when considering the sustainable use of our resources and the various requirements
of international building Energy Efficiency standards
such as BREEAM; LEEDS, DGNB?

1. The same light output from constantly reduced energy consumption
2. More light produced with constant energy consumption
Where do you find new ideas, inspirations?
In coping with our tasks day by day and in good and bad
architecture.
How do you relax? Do you have a favourite place for this
and who is allowed to accompany you there?
Relaxation is like inspiration: you’ll find it anywhere and
nowhere! In my leisure time I love to relax in the Alps
“accompanied” by the relevant seasonal “sports device”
(mountain bike in summer and snowboard in winter) and
my two, now grown-up sons.

The revitalisation of existing buildings often proves complicated. New user requirements are confronted with floor
plans of limited flexibility. Today’s demands made on interior design are opposed to irrevocably static elements –
innovative new building concepts could provide more elegant solutions here. Despite such difficulties the rebuilding
and conversion of the Lanxess Tower, a building complex
dating back to 1969 used by Lufthansa administration, has
achieved the standards of a new build beyond par. “With the
Lanxess Tower a new benchmark has been created for repositioning obsolete office high-rises. Furthermore, this redevelopment has significantly enhanced Cologne’s cityscape
on the right bank of the river Rhine.” For this achievement
Hochtief Projektentwicklung GmbH received the “Immobilienmanager Award 2013”.
The anchor tenant of the spaces re-designed by HPP Architekten is the specialty chemicals group Lanxess that will
move into all of the 22 top floors of the 95m tower. Anthracite, black and white are the determining colour design
features of the light-flooded rooms creating a backdrop for
the group’s CI colour. Lanxess already insisted on achiev­
ing inimitable signature interior design for the central lift
ante-rooms – after all, these functional areas, which provide
access to the entire building, are responsible for creating
that all-important first impression.
Timelessly elegant and soothing: the sleek ceiling panels with
compact LED Downlights in the central lift spaces
12
An anthracite, seamless terrazzo floor provides the
foundation for the floor-to-ceiling black glass wall panels
that starkly contrast with the white ceiling. Due to the
mirror effect of these panels all elements in the room are optically duplicated. At the same time, the “mirroring” makes
the various sizes of the projections less perceivable due to
the substance of the building. The lift portals, whose proportions are preset by the building’s static dimensions, were
designed as deep recesses in the wall surface and highlighted by an additional lighting component. The interior design
developed by Wolfgang Miazgowski of HPP Architekten
creates a striking “arc of tension” between extreme minimisation and virtual duplication. >

The RHEIN LICHT team did not have an immediate idea
for the illumination concept for the lift zones. There was
only one brief given at a very early stage and at the explicit
request of the specifiers at Lanxess: it had to be LEDs! Just
like with the entire complex of buildings pre-certified according to the DGNB Gold standard. And it was for the highrise of this building complex that Düsseldorf light planner
Ralf Schoofs had taken over the entire lighting design on
behalf of HPP Architekten. “The solution wasn‘t immediately obvious due to the complex room structure and design”
explained Ralf Schoofs adding “what was clear from the
outset, however, was that the illumination was expected
to consistently complement interior design beyond merely
providing functional indoor illumination.”
In WILA the lighting designer found a manufacturer that combines a good quality of light with well-designed LED technology
and is therefore available as a committed partner for individual
all-round solutions. Following the draft by Rhein Licht, WILA
engineered a frameless linear element that can be recessed flush
with the ceiling and which serves as a bracket and frame for
arranging the rhythmic array of square Downlight systems. Two
elements of this kind were assembled in the ceiling without tools
as offset pairs. The luminous efficiency, housing proportions and
dimensions of WILA’s Downlights proved an ideal match for the
task and these were also designed for tool-less installation. The
light aperture of these luminaire systems are equipped with an
opal-white cover and emit 1100 Lumen each at a colour temperature of 3000 °K achieving a mean illuminance of 300 Lux.
The lighting solution now implemented is the result of a
development process during which various options were
sketched out and explored. Rhein Licht finally came up with
a solution in partnership with WILA proposing a custom
design of a linear structure. This picks up on the design
elements of the room concept and symbolically recreates the
dynamic movement inherent to this busy area.
The design quality of such custom solutions and their appealing
integration into the interior concept only become apparent in the
“built state”. During this phase the WILA solution convinced all
parties involved and has enhanced the representative access areas
with its inimitable signature design. <<

One-piece mounting bar –

Functional passageways such as waiting rooms, corridors or conference
rooms are often fitted with grid ceilings. This is precisely the standard
that T-BAR LED uses as a basis for an entirely integral lighting solution:
Both mounting bar and lighting element at the same time.
Forming an integral part of the room’s architecture, the T-BAR LED system
makes for a calm, harmonious and tidy ceiling look. The LED modules used
as mounting bars offer flexible light solutions within this grid.
20
For individual solutions tuned to the purpose of the room the light
modules can be inserted in the ceiling grid either individually, as a
continuous line-up or arranged in a cross design.
As a rule, not all one-piece mounting bars can be replaced by linear light
modules. This means the T-BAR LED System opens up new, unobtrusive
design perspectives.

LED gear boxes
All LED luminaires shown in this brochure are sold without gear boxes to
provide you with the highest degree of flexibility. Two product lines with
distinct characteristics are available. The colour-coded LED gear boxes are
coordinated with the corresponding luminaire to reduce errors during
electrical installation. The electrical connection occurs via a plug connector
that is protected against polarity reversal.

Catalogue information
Many luminaires are protected by comprehensive design registrations,
patents and trademark protections. We reserve the right to change material,
design and programme without notice. Statements are not warranted
characteristics. Pictures and drawings are for illustrative purposes only.
Our terms and conditions of sale and delivery apply.
Luminaire luminous flux Llm
The luminaire luminous flux (Llm) defines the usable light of the luminaire
and is the decisive value in lighting design. As opposed to the lamp
luminous flux (lm), the luminaire luminous flux (Llm) accounts for losses
due to the design of the luminaire. WILA defines only the Llm value for
all LED lamps. This value can be found both in data sheets and in the
relevant ldt file.
System efficiency Llm/W
System efficiency defines the ratio of luminaire light flux (Llm) to power
input (W). Efficiency losses due to gear boxes have already been taken
into account by WILA in the Llm/W value.
System photometric data
For a qualified comparison between LED luminaires and luminaires
with compact fluorescent lamps, it is important to ensure first that the
products to be compared share approximately the same photometric
data. Sample calculation:
LED luminous flux 2000 lm (100%) – system losses (light output ratio) =
luminaire luminous flux 1720 Llm
UGR
The UGR method takes into account the layout of the luminaires in the
room and evaluates the glare produced by the entire lighting system
for a specific observer‘s position. WILA provides UGR values where the
observer’s position is parallel to the longitudinal axis of the luminaire and
the lamp/luminaire axis is parallel to the longer side of the room. The UGR
method is implemented on the basis of simple tables. A low UGR value
indicates that glare is negligible or non-existent.
Suitability examples UGR values:
< 16 for drafting rooms,
< 19 for offices and control rooms,
< 22 for precision industrial tasks
< 25 for light industrial tasks and
< 28 for heavy industrial tasks.
F marking
All WILA luminaires are suitable for use in or on ceilings of normal flammability and have so far been labelled with the F marking. With the publication of the EN 60598 standard, date of issue 09/2009, this marking is no
longer applicable. After the end of the transitional phase on 12.04.2012,
all luminaires without labelling are suitable for use in or on a ceiling of
normal flammability. Luminaires that do not fulfil the thermal requirements will be marked with a new pictogram in the future.
Luminous intensity distribution
In order to give a clearer overview, the luminous intensity distribution curves have been divided into groups. Shown are the planes from 0° to 180°
(red line) and from 90° to 270° (blue line). The 0° plane is on the right.
LED efficiency 2000 lm : 29 W = 69 lm/W
System efficiency 1720 Llm : 31 W (29 W LED module + 2 W driver) =
55 Llm/W
Heat sink
Beam chart
For accent luminaires beam charts are shown. The angle of the spread
out beam corresponds to the half-peak divergence angle of the luminous
intensity. Diameter and mean illuminance Em [lx] can be read from the
chart for each corresponding height.

Beam Spread Angle γ
The beam spread angle γ is defined as the angle at which the luminous
intensity drops to 1% of the maximum value lmax. It is measured from the
vertical (see luminous intensity distribution curve) and is an important
dimension in glare reducing measures.

Information about maintenance
The illuminance for a room/property must satisfy the published values
according to DIN 12464-1 over the entire period of usage; this corresponds
to the maintenance value. The electrical planner is responsible for
determining the maintenance factor dependent upon the lighting system
and the spatial conditions used and ensuring this with a maintenance
schedule. Further details about maintenance can be found in the
“Knowledge” section of our website at www.wila.com
Concrete mounting boxes allow the uninterrupted use of Downlights even
in exposed concrete and plastered ceilings. Thus the ceiling appearance
remains clean, and alternative surface-mounted luminaires are not required.
The two-part metal housing holds its shape and is designed for better
heat transfer; it also allows accurate positioning and fast installation while
meeting all legally required fire prevention regulations.
