システィーナ礼拝堂の照明が変わる

ローマ、ヴァチカン市国 内のシスティーナ礼拝堂へは世界中から多くの人々が訪れます。そして今秋からは、新しい照明とともにあのフレスコ画を見ることになるでしょう。
そこで使用されるLEDの光（スペクトラム）はミケランジェロの作品に合わせて調節されていて、日中に窓から差し込む自然光と同じ角度から光が当たるよう照明器具が設置されているそうです。おおよそ50〜100ルクスの明るさが得られ（以前は紫外線と赤外線を含むハロゲンランプで照らされていました、明るさは作品保護のため5〜10ルクス程度しかなかった）、劣化を最小限に押さえつつ作品が見やすく変わります。
さーて、システィーナ礼拝堂へ。
Around 7,000 LEDs will homogeneously illuminate the Sistine Chapel from next year onwards, enabling the world-famous works of art to be shown to greatest effect. The colour spectrum was custom-adapted on a scientific basis and with high precision to the colour pigments of the paintings, for example to the pigments in the Michelangelo frescoes. The highly precise guiding of light ensures that the art is uniformly illuminated, and without glare for visitors. The luminaires are to be installed away from view below the windows to make sure that light is emitted in the same direction as the natural daylight. Until now, the art could only be seen insufficiently and according to the ingress of daylight, and limited by technological and conservational constraints.
The conservational aspect, meaning protection of the art works, played an especially important role during the planning of the project, and the new LED solution is significantly gentler and more caring than all alternative artificial forms of light. Illuminance of approximately 50 to 100 lux (previously 5 to 10 lux) ensures that the art can be clearly discerned, but with as little ageing as possible.
