MUSEUM LIGHTING WITH LEDS: LED LIGHTING FOR THE SISTINE CHAPEL

摘要

The European Commission founded a pilot flagship project (LED4ART), which has the aim to demonstrate that high quality and energy efficient museum lighting based on LEDs is possible in 2014. The place of demonstration is one of the top ten museums in the world: the Sistine Chapel in the Vatican. A consortium consists of 6 partners from 5 countries are in charge of renewing the lighting system of the Sistine Chapel. Members of the consortium are OSRAM, the Vatican City State, OSRAM Italy, the Energy Research Institute of Catalonia (IREC), Fabertechnika and University of Pannonia. The role of the Virtual Environment and Imaging Technologies Research Laboratory in this project is to determine the LED spectral power distribution in order to present the world-famous frescoes to the visitors in the form as the artist imagined them. Beside this aspect, art preservation and energy efficiency are still important issues. The project has been started in 2012 with the evaluation of the old lighting system and going to reach the final aims in the first half of 2014. On-site measurements have been done in the Sistine Chapel, spectral optimization of LED spectra has been done according to modern colorimetric practice. In this paper, the most important results of the onsite measurement sessions are presented.
