Thorn索恩照明照亮也门国家奇观
“堪称国家奇观……”这是中东一家主流网站对也门首都萨那(Sana'a)新建成的萨利赫大清真寺(Al Saleh mosque)的描述。Thorn索恩国际销售部通过当地分销商Al Zaghir在这座宏伟建筑的照明之中起到了举足轻重的作用。
该项目最为显著的设计特征是泛光照明的使用，不仅体现了充分的想象力与敏感度，同时还全面而专业地把握了其中涉及的工程难题和光的分布问题。这座清真寺融合了也门建筑风格与伊斯兰经典元素（如尖塔、圆顶和拱门），由也门总统斥资6000万美元建成，可容纳44,000名信众。
混合使用Contrast和OQ 1000泛光灯，使寺庙外的灯光效果显得十分灵活多变；此外地面上还安装了一些嵌入式投光灯，在白天不易察觉。采用光线流技术而并非大量使用聚光灯，避免了出现阴影和干扰光，也不会使重点过于突出。该方案效果突出，六个尖塔均为100米高，夜间即便从很远的地方也能看到它们的威武雄姿。
如此复杂的项目需要进行大量光学计算，即便照明度可通过图纸规划，但灯光的美感只有亲眼所见才能做出评判。因此，Thorn索恩照明使用3D立体设计软件，为客户提供了色彩渲染且可旋转立体画面，模拟照明效果。于是，人们得以看到无法画在图纸上的建模效果，并得出了灯光亮度和色彩的最佳范围。
