Daylight solution for direct sunlight
A heliostat tracks the sun's position and directs sunlight into a hollow light pipe. This pipe transports the light several meters to where it is needed in the building—for example, to interior rooms, lower-level areas, or zones with limited natural light.
Depending on the system, the sunlight is directed through glass tubes or square light guides. Extractors designed specifically for each application then distribute the light throughout the room and, in combination with special films, diffuse it evenly into the surrounding area.
When there is no direct sunlight—such as on a cloudy day or after dark—artificial lighting can be turned on. This allows the Light Pipe be used as a combined daylight and artificial lighting solution.
Advantages
Application
Light Pipe Light Guide natural daylight into interior spaces that are dark or difficult to illuminate. Both systems expand the possibilities for daylighting in areas where traditional window solutions are limited by structural constraints.
The Light Guide primarily Light Guide to provide functional daylighting: it transports and distributes light precisely over long distances, thereby providing natural lighting even to deep recesses or building cores.
With the Light Pipe , the architectural effect Light Pipe a key role alongside the way light is directed. It combines daylighting technology with design and creates visible accents of light that not only make rooms appear brighter but also enhance their ambiance.
How it works
Light Pipe® systems are designed to capture direct sunlight. They therefore work particularly well when direct sunlight is available. The sunlight is captured by a mirror that tracks the sun—known as a heliostat—and directed into a hollow light pipe.
The light tube transports sunlight several meters to where it is needed in the building—for example, to interior rooms, lower-level areas, or zones with limited natural light.
Depending on the project, the light is directed through glass tubes or square light guides. Extractors designed specifically for each application distribute the light in conjunction with special films and emit it into the surrounding area in a controlled manner.
When there is no direct sunlight—such as on cloudy days or after dark—artificial lighting can be turned on. This allows the Light Pipe® to be used as a combined daylight and artificial lighting solution—offering a striking architectural effect and high-quality light.

The listed building is in a prime location on the Bosporus. Many interior rooms could not be sufficiently supplied with daylight. In close cooperation between the architect and the Heliobus daylight engineers, a light pipe was created over four floors. This provides the dark rooms with daylight and convinces with its aesthetic design at night.

In this international project, the challenge was to flood the interior of the station at Potsdamer Platz with daylight. Thanks to Heliobus Light Pipe , this problem was solved brilliantly: it is not only bright in the basement, but also an architectural highlight for tourists and residents.
