OZEANEUM STRALSUND:
FASCINATING LIGHTING DESIGN
The Ozeaneum in Stralsund, Germany, is the largest Baltic Sea museum. In four areas, the visitor can discover
the oceanic worlds of the Baltic Sea, the North Sea, the North Atlantic and the Arctic Ocean. It’s an experience
that is unique for many reasons, not the least of which is the perfect lighting design. Walter Bamberger was
responsible for the planning and implementation; he relied on Helvar DIGIDIM routers and DALI for the lighting
control.

tunnel, the visitor is
surrounded by water and
fish. Through the design of the
aquarium casing, in an almost black base tone and with minimal use of light, the
gaze of the viewer is drawn to the aquarium panes themselves and the fish swim-
ming behind them. The lighting design was chosen so that it would also be suitable
for the fish: There are bright areas in which sunlight is simulated and in which the
visitor can study the natural behavior of the fish, but there are also darkened areas
that serve as a refuge.
EXHIBITIONS
In the “World Ocean” and “Baltic Sea” levels, the goal was to design the display
cases optimally. A special high-performance LED spotlight system was developed
for this. Integrated magnet adaption makes it possible without tools to place any
spotlight onto contact rails that are flush with the display case profile. As a result,
every point in the display case can be illuminated. The LEDs cause the display
cases to appear to be independent luminous bodies.
GIANTS OF THE SEAS
For this area, artists created life-size models of whales that impart through their
size an impressive sense of the largest mammals in the world. In order to achieve
the most realistic presentation possible, twelve projectors are used to create an
underwater surface on the ceiling with water currents as would be experienced by

feel like they are in the ocean amid the whales. Whale
songs intensify this impression. Rotating structural panes,
various lighting technologies and blue filters create the
desired atmosphere.
The special ambience in this area is especially suited for
events. In order to give organizers as much freedom in
lighting design as possible, appropriate lighting control
interfaces have been provided. With DMX in and DMX
out, organizers can feed their own show effects into the
area’s light control system. A passive DMX network with
256 addresses is also available. The entire infrastructure
for this was also implemented with DALI.
TECHNOLOGY
In all, 15 Helvar DIGIDIM routers were installed. The high
reliability of Helvar DIGIDIM routers and DALI components
ensure fail-safe operation.
“We are very pleased that our lighting controls are used
with such demanding projects, as this demonstrates the
high quality of our components,” said Christian Wein,
Managing Director of Helvar GmbH.
In the foyer, there is a central control unit in the form of a
17” touch panel on which the entire lighting system can
be visualized. In addition, there are a total of 12 other
local control units available with 8” touch panels for local
control.
MAXIMUM ENERGY EFFICIENCY
A special feature is the integrated load balancing that
makes energy consumption calculable. A peak load was
specified for all building services that is not permitted
to be exceeded. If the building services management
system signals that the peak load has been reached, indi-
vidual lighting scenes can be switched off automatically
for a specified length of time. The necessary parameters
for this were set in advance. This, for example, allows
the cooling of the aquarium to have priority over the light-
ing system. The operating panels display whether load
shedding is active and which lighting scenes the system
has switched to temporary use.
The lighting is essential for each resident
of the Ozeaneum; wether it’s simulated
sunlight for a living Baltic sea fish or high-
lighting the giants of the seas.
