雕刻的光-斯特拉斯堡大教堂

CATHÉDRALE NOTRE-DAME DE STRASBOURG

斯特拉斯堡大教堂的照明设计让“光与影达成了一次美丽的邂逅”，“实现了令人惊叹的技术解决方案”。照明成为嫁接天地之间的桥梁，让黑暗与光明成为一种符号，点燃了设计者的想象与激情。

The Strasbourg Cathedral is, as one judge wrote, “a beautiful balance of highlighting and shadow” and an “impressive technical solution.” A bridge between the earth and sky, an icon of darkness and light, a monument that ignites the imagination and reveals the passion of its builders.

法国标志性的建筑斯特拉斯堡大教堂（CathédraleNotre-Dame de Strasbourg），近日由L'ActeLumière完成照明改造设计，该项目赢得了IALD 卓越奖。

The iconic Cathédrale Notre-Dame de Strasbourg in Strasbourg, France, with lighting design by L’Acte Lumière, took home an Award of Excellence, accepted in person by designer Jean-YvesSoetinck.

这座建于1176年的建筑被认为是哥特式建筑最伟大的杰作之一，曾被法国大作家雨果形容为“集巨大与纤细于一身令人惊异的建筑”。日前，改造后的斯特拉斯堡大教堂再现新的辉煌。六百个LED投影灯营造出温暖的灯光氛围，建筑的光与影形成鲜明的对比，在宁静、素雅的灯光下，建筑被塑造成了最庄严的艺术作品。

Considered one of the greatest masterpieces of gothic architecture, the iconic Strasbourg Cathedral revels in its newfound splendor. Six hundred LED projectors create warm accent lighting and highlights that contrast beautifully with the cast and modeled shadows, resulting in an overall glow and a peaceful illumination.

作为联合国教科文组织保护的古迹，L'ActeLumière设计团队在项目初期就向业主、投资人以及承包商分享及诠释他们的照明设计理念:照明设计师要通过有质感的光呈现这座哥特式建筑的宏伟与庄严。

As a UNESCO protected site, the team from L’Acte Lumière was required to present, account for and share their choices with the validation committee, which included the building owner, funders and contracting authorities from the city, as well as the heritage foundation. Designers were required to complete a manifest stating their commitment to qualitative light as they revealed the architectural magnificence of this iconic Gothic cathedral.

在深刻了解了建筑的结构以及其上面精致雕像折射的意义后，设计师精确计算用光，实现了光与影之间最佳的平衡。建筑立面由孚日山的粉红色砂岩石料筑成，（对应R8 - R9显色指数）。这种颜色很难通过二极管呈现出来。最终设计师选用色温2700K 灯具，色差小，以确保高质量的出光效果。该解决方案将整体照明环境纳入考虑范围，使得建筑本身的深色岩石材质以及其中的细节得以呈现。

After deep consideration of the sacred and iconographic facets and meanings of the structure, designers chose a precise and calculated balance of shadow and light to illuminate its presence. The brown and yellow sandstone comprised rich gradients of red and purples, corresponding to R8 - R9 CRI. This is a difficult color to render in high quality diodes, so designers selected a 2700K fixture with a short chromatic distortion to ensure quality light. This solution infuses a global ambient luminescence onto the structure, allowing the deep colors of the sandstone and its intricate details to be revealed.

重点照明被用来凸显建筑以及材质的层次，照明像写文字一样层层递进。动态白光 LED 灯具，柔和渐变的灯光和微妙变化的色彩用形成同一个建筑出现截然不同的两种夜景效果。

Focal glow and highlights were used to enhance the architecture and reveal detailed layers of masonry, like illuminated text. Dynamic white LED luminaires, soft gradients, and subtle tints were used to create two distinct nightscapes throughout the whole of the elevation.

建筑物上安装了长达14公里的电缆和400个光源。整个安装过程没用任何钻孔，灯具安装在砂浆接缝处。定制的套筒、项圈、紧固件和灯具被涂上与石材相似的颜色与建筑匹配。而且整个装置可以被拆除，并不会损坏建筑结构，这也是世界遗产委员会的关键要求。从外部看，除了地面的埋地灯，其他灯具均不可见，从而营造出了雕刻的光与充满诗意的建筑和谐相生的画面。

Fourteen km of cable and 400 light sources are installed on the building. The entire installation was completed without any drilling into the stone, only in mortar joints. Bespoke clamping sleeves, collars, fixture corsets and luminaires were painted onsite with an accurate color match to the stone. As a result of these considerations, the entire installation can be removed without any damage to the structure, which was a key requirement of the heritage committee. None of the luminaries, except those in ground, are visible from the exterior. This results in a balanced, quiet “chiseled light,” and a magnificent poetic glow of the building.
