The entire project cost some three million euros (US$3.77 million) — with 1.9 million euros spent on the lighting alone. The venture was funded in part by European Union funds, with the rest donated to the Vatican in expertise, technology and man hours by the various companies taking part.
A state of the art ventilation system has also been installed to protect the frescoes from humidity, enabling up to 2,000 people at a time to safely visit one of the world's top tourist attractions, which draws over six million people a year.Angels, sybils and prophets in blues, pinks and golds, once lost in the gloom, are brought into sharp relief by 7,000 LED lamps designed specifically for the prized chapel, where red-hatted cardinals have elected new popes since the 15th century.

VATICAN CITY -- High above the altar in the Vatican's Sistine Chapel, the halo around Jesus Christ's head in Michelangelo's famous frescoes shines with a brighter glow, thanks to a revolutionary new lighting system.

“The LEDs have a color spectrum specifically designed with the pigmentation of the frescos in mind to ensure the light faithfully reflects the original colors, as the artists intended,” said Marco Frascarolo, who works for Fabertechnica, one of the companies behind the new system.

“As each LED can be tuned to a different color, we spent long nights in the chapel with the Vatican Museum curators, trying out different mixes of red, blues, whites ... trying to get it just right,” he said during a private tour for journalists of the chapel late Wednesday.

While eight color samples are usually taken in an environment to create a LED system, 276 areas of the Renaissance paintings were analyzed, he said.

The sunlight which had streamed through the windows for centuries was shut out in the 1980s, when conservators realized ultraviolet radiation was damaging the masterpieces, causing the Last Judgment and other frescoes which cover the chapel's ceiling and walls to fade.

The lighting system put in place at the time was criticized for casting an unnatural glow and throwing some of the lesser known works by artists such as Botticelli, Ghirlandaio and Perugino into shadow.

A Whole New Light

The lights were vigorously tested to make sure they wouldn't damage the works, with pigments of the frescoes subjected to the LEDs in a laboratory at a high intensity which showed what effect the new system would have over 50 years.“The LEDs create a much better viewing experience because they throw light on aspects of the frescoes which were overlooked before,” Frascarolo said.

Protecting the artworks was also the driving factor behind the new ventilation system, installed by U.S. firm Carrier, which uses three cameras to monitor the number of people in the chapel and regulate the temperature and humidity.

“The previous system was only capable of regulating the air for up to 700 people. With this system the room can hold a maximum of 2,000 people without damaging the artworks,” said Michel Grabon, director of Carrier's AdvanTE3C Solutions Center.

“We know the amount of CO2 and humidity released by each visitor and can make adjustments accordingly, lowering the temperature or raising it if necessary to compensate for cold spells,” he said, adding that he can monitor the chapel from his home computer or mobile phone.

Both systems are also highly energy efficient, meaning the Vatican is expected to cut output for ventilation by around 60 percent and by up to 90 percent for the lights — shaving a vast amount off its bills.

Antonio Paolucci, the director of the Vatican Museums, said the chapel “contains the most extraordinary works ever conceived by the human mind,” and the new installations aimed to honor the 450th anniversary of Michelangelo's death by preserving and re-illuminating his creations.

The Vatican Museums said they were also exploring a project for next year whereby visitors craning their necks to see the famous depiction of Adam and God reaching towards each other to touch fingers could be given disposable “intelligent glasses” like Google Glass for a whole new 3D-view.

改造與新的LED燈後，西斯廷教堂炫

整個項目耗資三百萬歐元（約合3770000美元） - 與1900000歐元花獨照明。該合資公司資助的歐洲聯盟的資金部分，其餘捐贈給梵蒂岡的專業知識，技術和工時通過參加各個公司。
藝術通風系統的狀態也已經安裝了保護壁畫的濕度，最高可支持2000人同時安全地參觀了世界頂級的旅遊景點，它每年吸引超過600萬的人之一。天使，sybils和先知的藍色，粉紅色和金色，一旦失去了在黑暗中，由7000專為珍貴的教堂，那裡的紅盔樞機主教已自15世紀選出新教皇設計的LED燈帶到了鮮明的對比。

梵蒂岡城 - 高在梵蒂岡的西斯廷教堂的祭壇上面，圍繞耶穌的頭上的光環在米開朗基羅的著名壁畫閃耀著明亮的光芒，由於採用了革命性的新照明系統。

“這些LED具有專門考慮到壁畫的色素沉著設計了一個彩色光譜，以確保光線忠實地反映了原始的顏色，作為藝術家意圖，”馬可·弗拉斯卡羅洛，誰的作品為Fabertechnica，新系統背後的公司之一說。

“由於每個LED可以調諧到不同的顏色，我們花了很長的夜晚與梵蒂岡博物館館長教堂，施展出紅，藍，白不同組合......好一會才剛剛好，”他在一說私人旅遊的教堂記者週三晚。

而八色樣品通常採取的環境中創建一個LED系統，文藝復興時期的畫作276區進行了分析，他說。

它曾透過窗戶數百年流傳的太陽光被拒之門外，在20世紀80年代，當保護者意識到紫外線輻射被破壞的傑作，導致最後的審判，並覆蓋了教堂的天花板和牆壁褪色等壁畫。

到位的時候照明系統被批評為投不自然的光芒，並投擲了一些鮮為人知的作品的藝術家，如波提切利，基爾蘭達約和佩魯吉諾成陰影。

以全新視角

“因為他們扔光在這之前被忽視的壁畫方面的LED燈創造一個更好的視覺體驗，”弗拉斯卡羅洛說。

在燈光嚴格測試，以確保它們不會損壞的作品，用在高強度這表明新系統將有超過50年什麼樣的影響受到LED的實驗室壁畫的顏料。

保護作品也是新的通風系統，由美國公司運營，它使用三個攝像頭監視的人在教堂的數量和調節溫度和濕度安裝背後的驅動因素。

“以前的系統只能夠調節空氣達700人。有了這個系統，房間最多可容納2000人，而不會損壞的藝術品，“米歇爾Grabon，對運營商的AdvanTE3C解決方案中心總監說。

“我們知道，CO2和濕度每個訪問者的釋放量，並可以進行相應的調整，降低溫度，或者如果需要補償寒流提高，”他補充說，他可以從他家中的電腦或移動監控教堂手機。

這兩種系統也非常節能，這意味著梵蒂岡預計減產通風約60％，而高達90％的燈 - 剃了大量斷其賬單。
