What kind of ideas will be implemented in the indispensable night lighting of the Shanghai World Expo Park? What kind of dream-like world of light and shadow will the World Expo offer? To this end, we interviewed Professor Hao Luoxi, the person in charge of the overall planning of the night scene lighting of the Expo Park and the Lighting Art Research Center of Tongji University.
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.â€
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.â€
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.
"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 “rotatedâ€, 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 “signatureâ€. .
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 will increase the LED floodlighting and add color lighting effects. “Thinking, the beautiful lights or the scattered or scattered, the swaying rivers are colorful, 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.â€

2.54mm (.100") Pin Headers
Antenk`s line of 2.54mm pitch pin headers are durably made for high vibration environments, for board-to-board or PCB to PCB Connectors, with industry-leading current of 3.0A. Designed for low-profile applications, this pin header is made from high-temperature thermoplastic and is offered with several means of connections and mounting styles such as through-hole (THM) or surface mount (SMT) and can be in vertical (straight), elevated or at a right angle configuration/orientation
Pin header customization is also available upon your request. The 2.54mm pitch pin header is highly recommendable for signal and low power PC board connections when space is at a premium and when 1.0mm and 1.27mm pitch headers cannot dissipate the required current. In addition, the 2.54mm pitch pin header holds an excellent mating quality that fits with various types of female connectors.
Applications of 2.54mm Pitch Pin Headers
Motherboard Connectors
The Motherboard of a computer holds together many of the crucial components such as the central processing unit (CPU), memory and connectors for input and output devices.
Printer Connectors
Automotive PC Connectors
Smart, high power automotive PC power supply garners its capabilities from quality pin headers, designed for general purpose battery powered applications. These are manufactured to provide power and to control the motherboards' switch based on ignition status.
Battery Connections
Rechargeable battery packs, battery balancers, battery eliminator circuits. Battery connections rely on the ability of the current to pass reliable and solid current. This prevents overheating in the circuit and voltage drop.
Medical Diagnostic and Monitoring equipment
Communications: Telecoms and Datacoms
Industrial and Automotive Control and Test
Mount Type: Through-hole vs Surface Mount
2.54mm pitch pin (male) headers are offered in either Surface-mount or Through-hole mount termination. At one side of this pin header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).
Through-Hole (Poke-In)
Best used for high-reliability products that require stronger connections between layers.
Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
2.54mm vertical single row header, 2.54mm vertical dual row header, 2.54mm Elevated single row pin header, 2.54mm Elevated dual row pin Header, 2.54mm Right-angle single row header and 2.54mm Right-angle dual row header are some examples of Antenk products with through-hole mount type.
Surface-Mount
The most common electronic hardware requirements are SMT.
Essential in PCB design and manufacturing, having improved the quality and performance of PCBs overall.
Cost of processing and handling is reduced.
SMT components can be mounted on both side of the board.
Ability to fit a high number of small components on a PCB has allowed for much denser, higher performing, and smaller PCBs.
2.54mm Right-angle Dual Row pin header, 2.54mm SMT Single row pin header, 2.54mm SMT Dual row pin header and 2.54mm Elevated Dual Row Pin Header are Antenk`s SMT pin headers.
Soldering Temperature for 2.54mm Pitch Pin Headers
Soldering SMT pin connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.
Pin-Type: Vertical (Straight) and Right-Angle
2.54mm pitch headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle male header.
One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called "straight" or [vertical") or.
Right-Angle Pin (Male) Header Orientation
Parallel to the board's surface (referred to as "right-angle" pins).
Each of these pin-types have different applications that fit with their specific configuration.
PCB Connector Stacking
Elevated Pin Header Orientation
Elevated pins aka Stacked Pins or Mezzanine are simply stacked pin headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.
This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.
Single, Dual or Multiple Number of Rows
For a 1.0mm straight or vertical male pin header, the standard number of rows that Antenk offers ranges from 1 to 2 rows. However, customization can be available if 3, 4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins while for dual row, the number contacts may vary from 2-80 pins.
Pin Material
The pins of the connector have been designed with copper alloy. With customer`s demand the pins can be made gold plated.
Breakaway design
The pin headers are also equipped with a breakaway design making them fully compatible with their female receptacles.
Custom 2.54mm Pitch Pin Headers
Customizable 2.54 mm pitch pin headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed.
Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.
Tape and Reel Packaging for SMT Components
