Advantages of HLG

• Lamp and Luminaire are separated

• Light Sources with high luminous flux can be used

• Maintenance is simplified, thus reducing costs

• Light (artificial and daylight) can be transported over

a long distance

• Light can be coupled out uniformly


System scheme

I Headmodule - Heliostat with EIB/LON-interface

II Mixmodule - Addition of Sulphur Lamp Light

Depending on the Available Amount of Daylight, EIB/LON-interface

III Transportmodule - Efficient Light Transport With Hollow Light Guides with High-reflective Materials (OLF, Miro)

IV Luminairemodule - Light Output without Glare

The lighting should

• supply the staircase with a sufficient amount of light to use the staircase in a quick and safe way

• give good modelling to the people, meeting in the staircase

• provide good adaptation to the light quality in the connected rooms, which are illuminated by daylight (at daytime)
