2010年11月，随着武进电视塔景观照明工程的顺利竣工，国内高塔夜景照明项目中又增添了一个经典案例。228米高的塔身，被装扮一新，夜幕下的武进电视塔光彩闪耀、动感飘逸，成为整个武进地区一颗耀眼的明珠
November 2010, with the successful completion of façade lighting construction, Wujin TV Tower becomes another shining example of megatower lighting projects. With a body that is 228-meter-high, the tower is dressed up in a new light at night that is dynamic and elegant, making it a dazzling pearl in the entire area

项目背景
武进电视塔高228米，是国内县一级高度最高、功能最全的钢结构塔，有“全国县级第一塔”之誉，是中国高塔委员会成员塔，也是武进城区的标志性建筑和形象工程。武进电视塔所处的武进新天地不夜城商业中心是集餐饮、购物、娱乐、休闲、旅游、运动、居住等多功能于一体的主题型商业街区。而武进电视塔就处于该商业中心的核心位置。
项目总体介绍
武进电视塔景观亮化工程项目中，采用了如 LED 全彩线性洗墙灯、LED 全彩投光灯、LED全彩点状灯、LED 竹节模组灯等14种不同类别的景观亮化灯具，其中有10余种 LED 景观亮化灯具都集中纳入了 LED 灯光控制系统，通过灯光控制系统的协调、统一控制，使塔身6700多套LED灯具实现多种动态灯光效果，以及多场景的灯光艺术表演。

设计目标
项目的宏观目标为“打造现代、动感、华光溢彩的标志性光环境”。具体实施起来，整个塔身被分为上中下三个区域，内外三个层次控制到每套灯具，使塔底大圆盘周身，塔身每个大米字型钢结构，每根柱子的法兰结点，井道的每层，半球穹顶，及塔顶小米字结构和三层平台周身，既能彼此独立的表达不同的灯光效果，又能相互协调展现统一及连贯的多场景变化。
艺术灯光控制系统：
武进电视塔的LED灯光控制系统采用了先进的 DMX512灯光控制系统，该控制系统的信号控制与传输分为三级，如图5所示。
第一级LED图像控制系统控制计算机与3套LED工控机之间的信号传输，采用星型连接，由计算机发出总的信号，统一传输给3台 LED 工控机；
第二级LED工控机与长距离信号接收器之间的连接，也是采用星型连接，LED 工控机发出信号传输给控制范围内的若干套长距离信号接收器；
第三级由长距离信号接收器通过干线制的方式将信号传输给该通道内的灯具，每套灯具都内置程序控制芯片，从信号干线上读取自身需要的控制信号。
采用星型网络拓扑结构及DMX512灯光控制协议的优点是某套灯具的故障不会影响到其他灯具的正常工作，而单套控制设备的故障也仅对该设备控制范围内的灯具有影响（但灯具自身不会损坏），不会涉及到其他灯具及控制设备的正常工作。

从控制范围划分，整个塔身被3套LED工控机划分为上下三个区域，内外三个层次的三维空间控制分区：
第一个区域是200米高塔顶部全彩点状灯具往下至155米高半球穹顶全彩棱镜点状灯具止；
第二个区域是142米高第一层大米字结构往下至50米高大米字结构止；
第三个区域是33米平台位置往下至塔底止。
最外层为塔身法兰结点处竹节模组灯；
第二层是米字型结构大功率投光灯及全彩点状灯；
最里层为井道全彩大功率投光灯；
这些不同区域，不同层次的 LED 景观灯具，通过系统的统一协调控制，可实现整体同步灯光效果。
通过设置不同灯光变化程序，不同控制场景模式，可实现如塔身整体全彩变化，塔身至上而下（或自下而上）的全彩变化，大米字结构中心点状灯具的星空闪烁，半球形结构的点状灯具旋转变化，竹节灯的逐层递增变化等等。

Project background
Wujin TV Tower has 228 m height, is the highest and the most versatile steel tower at county level. As a landmark in Wujin City, it is a member of the High Tower Committee of China. The tower is located in Wujin Business Center, which is a theme-oriented commercial district with dining, shopping, entertainment, leisure, tourism, sports and housing. The Wujin TV Tower is the heart of the commercial center.
Project overview
For the project, 14 different types of landscape fixtures were implemented such as linear full-color LED wall washer, LED full color flood light, LED full-color spot lights, LED bamboo node fixture. More than 10 kinds of fixtures are controlled by the lighting control system through centralized and computerized coordination, so that over 6,700 sets of LED fixtures can deliver a variety of dynamic lighting effects and multi-scene light shows.
Design objectives
The main objective of the project is to “build a modern, dynamic, signature light environment”. Specifically, the control over the whole tower is divided into three sections vertically, lower, middle and higher and the three layers from inside to outside horizontally. In this way, the large disk over the bottom of the tower, each of Chinese character “rice” shaped steel tower, the flange end of each column, each layer of wells, hemispheric dome, and the top of the tower structure and three platforms all can have different lighting effects as well as a unified and coherent coordination of multiple scene changes.
Artistic lighting performance control system
Wujin TV Tower LED lighting control system uses the advanced DMX512 lighting control system, the control system is divided into three tiers of signal control and transmission, as shown in picture 5.
Level one, LED image control system manages the signal transmission between computer and 3 sets of LED Industrial Personal Computer (IPC). In a star connecting mode, all the signals are sent by the computer to 3 LED IPCs.
The connection between the second tier LED IPCs and long-distance signal receiver is also in star connecting mode
The third tier consists of long-distance signal receiver system which sends the signal to each fixture through the trunk mode; each fixture has a built-in program control chip which enables the fixture to read the needed control signal from the signal line.
The advantages of applying star network topology and DMX512 lighting control protocol is that a set of fixtures failure will not affect the normal operation of other fixtures. In addition, a single set of control equipment failure can only affect lighting equipment within the control ranges (the fixture itself is not damaged) and other fixture and control equipment can still work properly.
The entire tower has 3 sets of LED IPC is divided into three zones from top to bottom, three layers from inside to outside:
From top to bottom:
The top section is from the 200-meter-high top of the tower to 155 meters high hemispheric dome-shaped which is lit by full-color prism fixture;
The second area is between 142 and 50 meters down below the “rice” character shaped structure;
The third area is 33 meters downwards to the end of platform.
From outside to inside:
The outermost layer consists of flange bamboo node fixture;
The second layer is rice character shaped structure of high-power floodlights and full-color spotlights;
The innermost layer is full-color high-power floodlights;
The LED landscape lighting for these different sections are synchronized to achieve the overall lighting effect.
