STAR LIGHT REVERIES—Beijing Gemdale Plaza

金地广场建成于2007年，此次金地集团对商业业态与定位做出了全新调整，邀请了建筑师和灯光设计对建筑与室内空间进行全方位的改造。

Gemdale Plaza was built in 2007, this time Gemdale Corporation is committed to make a brand new impression towards their positioning by inviting architecture and lighting designer to redesign their architectural and interior design.

“钻石”与“涟漪”，是建筑师LLA赋予金地中心的新理念，从大体块的玻璃幕墙造型、玻璃上涟漪的纹样，以及室内简洁、现代感十足的装饰语言，金地给人新鲜、时尚的感觉。而在夜间，灯光让此次全新的形象格外明确与突出。

“Diamonds” and “Ripples”, are the new concepts of Gemdale Plaza given by LLA. From ripples on the huge glass facades, to the minimal, contemporary decorative language, Gemdale has given people an impression in line with time. At night, lighting further accentuates the modern and innovative style of the redesign.

在整体夜间效果中，双层幕墙玻璃内由光织就的表皮最为耀眼。建筑幕墙复杂的钢结构往往是照明的难点，与以往千篇一律的均匀光和发光盒表达水晶体的传统照明手法不同，我们用点光演绎钻石的璀璨与晶体的结构感，反而利用了它本身的结构特点。光源本身的直视光、照射在铝板上的光、玻璃的受光、空间光，共同拼凑出晶体多面感、立体感与通透感，令整个设计团队也很惊喜。此外，在控制变化上，通过间歇的控制来诠释，并搭配动态“呼吸”感的变化，在恍若钻石般星光的效果中，无序且有节奏的明暗与闪烁，迎合着观赏者的心跳与呼吸，在璀璨和静谧间，自由收放，给人更直接、也更丰富的感官感受。

Overlooking the architecture at night, the most eye-catching aspect is the light covered facades. The complicated steel structure was rather difficult to illuminate. Instead of lighting the surface uniformly or creating a crystal light box, we took the advantage of the steel structures and brought out the aspects of shine by creating a point light effects. To our surprise, an outstanding multi-surface three dimensional transparent effect is achieved through combining light from the light source, aluminum plate, glass, and space. In addition, intermittent control was designed coordinating with the “breath” of shine; dimming and shining rhythmically with the heart beat and breathing of viewers. Between the blink of shines, an ever more direct and rich sensory feeling is achieved.

LED各种特点之一，便是它多变的色彩，在商业照明中甚多使用。而我们的灯光设计从总体考虑，却单单使用4000k，用亮度控制，形成最纯粹的光的强弱变化；配合特殊商业场景需求，每个单点是单独控制的，相邻单点像素可以自由组合，通过疏密、速度变化，变幻出似有若无的图案。“想象”将来源于每个看到它的个体，想象成是“星光”、“雨滴”、“雪花”还是“风的涟漪”或者“飘散的蒲公英”…… 每个人都能找到属于自己的感受与心情。与传统的大面积的LED色彩变化的热烈、喧闹相比，更显清新，亲切。

Colour change is one unique characteristic of LEDs; it is used commonly in commercial lighting. However, with overall consideration of design, 4000K is the only colour temperature used in this project. Intense and dimmed lights are simply achieved through luminance control. In addition, in order to fulfill special commercial needs, each point could be controlled individually; pixels of adjacent points group freely, allowing patterns created through spacing and rhythmic changes. “Imagination” is subjective, one could interpret it as shining stars, water drops, snowflakes, and others could see it as ripples of wind or scattered dandelion…. Each viewer would find their own feelings within their own imagination. Comparing with the commonly used large and colorful LED facades, the point light system seems much more fresh and sincere.

要在单反玻璃与彩釉玻璃后部发挥单点LED光的效果，是中间的另外一个难点也是重点。双层玻璃幕墙是为灯光设计定制的，灯光低透率与漫射光光衰成为本项目定制的重点。通过数月反复的玻璃材料比选、LED透镜的不同切割方式测试与光源光通计算，建筑顾问、幕墙顾问为灯光的多次方案调整，玻璃供货商、灯具供货商协助开发，并多次的大面积打板测试。实际效果中，每一颗led从整体看只是看似平凡的一个光点，放大这个点就会看到全新的光扩散技术与背衬板及玻璃完美的呼应，LED芯片的光通过沙漏型导光透镜汇聚并引导至定制的不规则型切割的扩散透镜中部，并通过扩散透镜形成钻石般光芒。得益于业主的信任，以及整个金地顾问团队的共同努力与各材料厂商的技术支持，才能使这个项目最终实现。

Another critical difficulty was to achieve the LED point lighting effects behind a SLR colour glazed glasses. The double glazed glass façade is specially made for lighting design. Its low lighting penetration rate and drop of diffused light became the critical aspects of this project. After months of multiple comparisons between glass materials, optical lens cutting techniques, lighting calculations and design concepts, in addition with help from glass and lighting manufacturers, and multiple model tests; the perfect balance between point light diffusing techniques, back plate, and glass was finally achieved. Zooming into each ordinary point light, light from the LED chip goes through an hourglass shaped lens, fusing into the mid-section of a custom cut diverging lens, finally shines through the diverging lens forming the sparkles as a diamond. This project could not be completed without the trust of client and the help from every consultant and manufacturer.

而裙楼外表皮的这些LED点光，并不是单独存在的。从建筑塔楼顶部，到室内中庭的造型天花，甚至景观的植物照明，依据建筑形式、装饰特点以及环境氛围，“星光”会以不同的形式不经意的出现，彼此呼应，平衡明暗、延续气氛。当然，人们身临其中，通过视觉感受到的，无关“理念”与“技术”，只有“舒服”、“欢愉”与“惊奇”，而我们期待的，也正是有人记住这些感受，享受这份“美好”。

The LED point lights on this building façade do not exist solely on its own. From the top of the tower to the ceiling of the interior atrium, even the plant lighting; the concept of “Star Light” has been casually integrated into the spaces based on the form of architecture, decorative details and the mood of environment. For the viewers, it is neither about “concept” nor “techniques”; it is about “comfort, “joy” and “surprise”. And all we have ever expected is for the viewers to remember and enjoy these wonderful feelings.
