LEDs in Museums: New Opportunities and Challenges

The national and international requirements for the lighting of museum pieces are presented based on the results of researches carried out in the second half of the 20th century and which should be actualized in connection with the introduction of LED lighting into the museums. In addition, the spectrum diversity of the LED sources needs to address the issue of changing the approach to the assessment of museum lighting, in particular, the transition to the new colour rendering indices (Fidelity Index and Gamut Index) according to the CIE, and the use of energy and/or photonic values in addition to light values.
