Light Pipe - Capture sunlight and direct it into the building

Daylight and design combined as light art. Light Pipes capture direct sunlight and guide it into interior spaces through mirrored hollow light guides.

Daylight system for more daylight over several floors - Light Pipe

Daylight solution for direct sunlight

A heliostat follows the sun and redirects the sunlight into a hollow light guide that transports the sunlight over many metres to where it is needed. The targeted deflection into the desired zones is usually done through a glass tube. However, square light guides can also be used . Object-specific extractors in combination with a special foil distribute the transported light and emit it to the surroundings. If there is no sunshine, e.g. on a cloudy day or at night, artificial light can be switched on to illuminate the Light Pipe .

Advantages

Innovation for Design & Light Art

Cross-zone supply with daylight

Natural core zone lighting

Improvement of the room atmosphere

aesthetic design

Can be used for central lighting after dark

Application

The Light Pipe and the Light Guide bring daylight into interior, dark rooms. While functionality, i.e. the idea of lighting, is in the foreground with the Light Guide , the design idea dominates with the Light Pipe .

How it works

Light Pipes are pure sunlight systems. They therefore only work with direct sunlight. The sunlight is deflected into a hollow light guide by means of a mirror that tracks the sun, the so-called heliostat, and transported over many metres to where it is needed, as is already the case with Light Guide. The targeted deflection in the desired zones is usually done by means of a glass tube. Square light guides can also be used. Object-specific extractors in combination with a special foil distribute the transported light and emit it to the surroundings. If there is no sunshine, e.g. on a cloudy day or at night, artificial light can be switched on to illuminate the light pipe.

Daylight Engineering in the Turkish metropolis

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.

Basement lighting supply Potsdamer Platz, Berlin

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.
