A temple for the art of lighting
A selection of Thorn's exciting exterior luminaires - Band, Cesar and Milo - have been used to illuminate Antwerp's Royal Museum of Fine Arts (Koninklijk Museum voor Schone Kunsten).
This remarkable 19th century temple of art is decorated with Corinthian columns and adorned by two large statues, depicting two-horse chariots. The museum itself displays a fine collection of Flemish paintings including work from Rubens, Van Dyck, Jordaens and Brueghel.
The architect wanted to create a hierarchy of illuminance without overlighting, whilst paying special attention to focal points such as the chariots, which serve as the museum's logo.
LED Band luminaires, many DALI controlled, are used for the base of the chariots, above the entrance doors and for backlighting the pink galleries that house the busts - each figure being lit from above by two Milo LED spotlights.
The columns and verticals are lit by Cesar projectors (35W HIT), augmented by various Contrast (35W & 70W HIT) and LED MiniPinspot spotlights. A mix of warm (3000K) and cool (4200K) colour temperature lamps are used to vary the colour appearance.
The overall result is a sensitive scheme which has unity and beauty. At the same time electrical consumption has been halved.
