Hao Luoxi: Night Scene Lighting of Shanghai World Expo Park

What kind of ideas will be implemented in the indispensable night lighting of the Shanghai World Expo Park? The World Expo will offer a dreamy world of light and shadow. To this end, we interviewed the head of the overall planning of the night lighting of the Expo Park and Hao Luxi, the lighting art research center of Tongji University. professor.

Five concepts to plan lighting context

"Using efficient, integrated, humanized and sustainable technology to achieve the beauty of the park's lighting." The gentle and elegant Hao Luoxi is like a few treasures. She said that the lighting planning concept of the Expo Park is divided into five sections:

At the strategic level, plastic energy-efficient urban lighting examples; cultural level, creating an ecologically-protected lighting mode for the historical sites of the Expo site; technical aspects, the first large-scale integrated application of semiconductor technology in the best urban practice area of ​​the World Expo; humanities At the level, let people enjoy the creative life brought by lighting technology in the interactive experience with lighting art; realize the maximization application of “Made in China” products at the industrial level.

She said: "For example, the old factory buildings in the Expo Park, how the lighting landscape can achieve harmony with the protection of the building under the new technical conditions, the elegant connection with the surrounding environment, the brightness grading of the lighting, the color temperature of the lighting, the arrangement of the light spots... We are Refine planning and design solutions."

Light source creates Dream Expo Park

"According to this concept, we divided the night illumination of the Expo site into four areas." Hao Luoxi introduced that dynamic color lighting is mainly in the public areas such as festivals, Expo Axis and Zhouqiao. According to the function of the park, the four areas we divided are:

Areas that use color dynamic light include the Expo Axis, the Pontoon Bridge, and the Axis Building (Performance Center, Theme Pavilion, and China Pavilion). “These places require the use of colored light illumination combined with dynamic light changes.”

Areas where small amounts of color dynamic light are used include active green spaces, collection squares, and elevated walkways. A small amount of colored light illumination is required to enhance the fun of walking paths and activities, and to control the dynamic change of color and color.

Areas that do not use color dynamic light include riverside landscape green spaces and green areas outside the stadium area. “The peripheral green space is close to residential areas. It is not advisable to use colored dynamic light. If used, it will not only affect residents’ normal rest, but also cause light pollution.”

Others mainly refer to self-built pavilions and leasing pavilions, including foreign pavilions, corporate pavilions, museum exhibition halls, and best practice district pavilions. A small amount of colored light illumination can be used, and the dynamic change control of color and color can be performed, depending on the situation of each museum.

"I believe that through control, we will show the world a fantastic World Expo Park." Hao Luosi said.

Shanghai World Expo Park night lighting

"Mother River" will participate in the lighting show

"Under the night, the mother river Huangpu River will also participate in the lighting show." Professor Hao smiled and opened her face, filled with intoxication.

The Puxi Approach Bridge of Nanpu Bridge is beautifully shaped, and the spiral shape of the curve is elegantly “rotated”, and the upper and lower rings are separated. We will carry out appropriate decorative lighting design for the pylons and cables during the World Expo, such as adding different colored light illumination to the pylons, and projecting the color cast light with a small beam angle on the suspension cable, highlighting its “signature”. .

The world's first steel structure arch bridge Lupu Bridge's sightseeing platform is located at the highest point of the arch rib, 110 meters away from the Huangpu River, like a "laurel", it is an excellent point to watch the Expo "Flower Bridge". During the World Expo, its arched structure and intermediate tie rods appropriately increase the LED floodlighting and add color lighting effects. “Thinking, the beautiful lights or the scattered or scattered, the swaying rivers are colorful and people will be drunk.” Professor Hao said.

The design of the pontoon lighting, and the contrast of the water and shadow of the river surface, the swaying effect is a surprising new point for the design team. "We will let the pontoon bridge and the river face whisper and tie each other." Professor Hao stressed.

Tan Xingzheng’s Professor Hao said that other lightings such as green spaces, such as the city’s best practice areas, such as the World Expo Tower... “writing “harmony” with light and writing contemporary Chinese style is our highest concept.”

Flex PCB Assembly = Flex Printed Circuit Board Assembly, which means the PCB Board is flexible. Normally, flex PCB is made with PI or ultra-thin FR4 and it's very thin. Normally, Flexible PCB would need carriers for SMT assembly if by machine. Zhongfeng would manufacture the PCB boards follow the design file, source the components follow the BOM file and do the PCB Assembly job using carriers to follow the assembly drawing and the pick&place file. After PCB assembly done, the components would be mounted on the PCB boards tightly and connected each other through the copper circuits. We call such board as PCBA board or flex PCBA board.

Depends on the components assembly types, it have THT PCB assembly, SMT PCB Assembly , one sided SMT and THT PCB assembly, two sided SMT and THT PCB assembly.

Depends on the PCB type, it have Rigid PCB Assembly, Flex PCB assembly and Flex-Rigid PCB Assembly.

Also we would call some PCB assembly types as Prototype PCB Assembly, Mass PCB Assembly , Turnkey PCB Assembly, LED PCB Assembly and BGA PCB Assembly , etc.

With our 15years professional experience, we are available for all types of PCB assembly service from prototype to mass production, available for 01005, 0201, 0.3mm BGA, 0.3mm QFP.
