Ten Challenges: Hong Kong Zhuhai Macao Bridge Lighting Project

- Oct 25, 2018-

October 23rd nine, Zhuhai, China.

The Hong Kong-Zhuhai-Macau Bridge, a super-project that has been under construction for nearly nine years, has officially opened under the global spotlight, which means that the 55-kilometer-long, most prolific cross-sea bridge in the world has finally been unveiled.——LED Bridge lighting

At this moment, the team of Shanghai's third thought also couldn't restrain its excitement. Because the LED street lamp, LED tunnel lamp, LED landscape lamp, LED overhaul lamp and LED variable information board and other products used by the Hong Kong-Zhuhai-Macao Bridge are all tailored by Shanghai Sansi, totaling nearly 30,000 sets (platforms), which is a landmark project in China and even in the world.——LED Bridge lighting

After more than five years, I finally handed out a perfect answer at this moment. The ups and downs of this can only be experienced by their own participants and a large number of silent supporters.

To be exact, the lighting project of the Hong Kong-Zhuhai-Macao Bridge is a record of the challenge of LED lighting technology to the extreme natural conditions, and a witness of Shanghai Sansi LED black technology.——LED Bridge lighting

Today, Wang Yinghua, President of Shanghai San Si, tells the story behind the lighting project of the Hong Kong Zhuhai Macao Bridge.——LED Bridge lighting

"This is not the general road and bridge lighting."

The Hong Kong Zhuhai Macao Bridge project has higher requirements for lighting than most people think. Its greatest challenge lies in the extreme natural conditions. Wang Yinghua pointed out the biggest difficulty of the project. The bridge supervisor and the construction unit have given ten natural factors which need to be considered for the bridge, namely, the assessment index is calculated on a ten-point scale, and each item must reach a very full mark before it can reach the standard.——LED Bridge lighting

"This means that each LED lamp and information board, in addition to lighting and display functions, but also to meet the above 10 special requirements." Wang Yinghua pointed out that each product must be customized and special treatment, from the chip, packaging to appearance, technology, and materials and lighting technology, to develop customized solutions.——LED Bridge lighting

This high standard and high requirement near the limit, on the contrary, can highlight the unique advantages of Shanghai Sansi, Sansi's comprehensive competitiveness in this super project more vividly reflected.——LED Bridge lighting

Founded in 1993 in Shanghai, Sansi has more than 2,000 employees, of whom more than 400 are research and development teams (one Research Institute and 13 research institutes), covering computer software and hardware, electronic communications, automatic control, photoelectric display and lighting, mechanical structure and other disciplines and industry chain research. Almost all major topics are It can be solved internally. It has become the leading or undertaking unit of key research projects in 863, 11th, 12th and 13th five-year plans.——LED Bridge lighting

A hundred competitions, think twice and win the bid.

"After many rounds of contests, the project of lighting and LED information board of the Hong Kong-Zhuhai-Macao Bridge has been won, and finally the encirclement has been highlighted." Wang Yinghua said, this is a comprehensive strength of the big test, began in early 2013.——LED Bridge lighting

At the beginning of this year, the Hong Kong-Zhuhai-Macao Bridge Authority inspected nearly 100 advanced domestic and foreign enterprises, including Sansi, and almost all of the world's well-known lighting brands. After the first round of primary elections, Shanghai's third thought is the list of suppliers.——LED Bridge lighting

The real contest was in 2014. As the general contractor of the project, China Railway Construction requires all the suppliers to put forward the system solutions of lighting and LED variable information board display according to the project design scheme.——LED Bridge lighting

After several rounds of bidding, Shanghai Sansi finally by virtue of comprehensive strength and comprehensive solution capabilities, from all bidding enterprises stand out and win the bid at one stroke. One expert commented that LED lighting and display display both have strong advantages, which are rare in domestic and foreign enterprises.——LED Bridge lighting

For world-class super-engineering, the bridge for suppliers to choose more than one or several indicators, is a comprehensive all-around test.——LED Bridge lighting

Unique innovative technology to conquer extreme conditions

Wang Yinghua said that in order to meet the bridge's limit conditions, Sansi's many unique innovative technologies were applied to the bridge's LED lighting products, including ceramic heat dissipation technology and reflective luminescence technology.——LED Bridge lighting

The key research achievements of the 863 national plan. A single ceramic is an independent ceramic radiator. The LED chip is directly attached to the ceramic radiator without PCB. The heat is directly emitted into the environment through air convection, so that the node temperature of the LED chip is lower. Heat dissipating lamps create disruptive innovation.——LED Bridge lighting

Think twice of ceramic modular LED lamps and lanterns have gained world intellectual property rights patents.

Reflective light emitting technology

The key research achievements of the 863 national plan have already possessed proprietary technology of intellectual property rights. Lambert body light distribution and three-dimensional reflective cavity design, further improve the lamp's reflective efficiency, uniformity and comfort. Light can not see light beads, bright and not dazzling, for tunnel access to improve safety.——LED Bridge lighting

In addition, think twice for pioneering design and application in other applications.

1. arc design

Sea salt fog, strong typhoons often patronize. The arc design can not only reduce the accumulation of salt spray and dust into the lamp body damage parts, the most important thing is to improve the level of windproof, can resist 16 typhoon.

2. steel lock tongue

In order to further improve the level of anti-salt fog, anti-ultraviolet and high and low temperature resistance of the information board, a number of new technologies and new materials are adopted, and only one tongue is locked, the steel products are customized for the bridge.

3. remove the opening to ensure heat dissipation.

No opening at the top of LED street lamp. On the premise of using ceramic heat dissipation technology to fully dissipate heat, remove the top hole, but also prevent salt spray water vapor intrusion, improve the reliability of LED street lamps.

4. lens customization

Under the condition of uniform illumination, the brightness uniformity can be enhanced and the zebra crossing effect eliminated.

5. anticorrosive spray

Enhanced anticorrosive spray is more durable, and the details are attentive.

6. system

Luminance demand from 0 to 100% brightness adjustment, more energy saving and environmental protection. Nightscape lighting is a combination of remote centralized control, automatic control and manual control, which can adjust the opening time and section according to the need, and effectively monitor the color of the light and the state of the lamps.

7. high power factor

The power factor of street lamp and tunnel lamp is greater than 0.98, reducing the load of the network.

8. single lamp control

Set up a data processing, visualization platform to accurately monitor the operation of each lamp, automatic fault feedback, efficient and convenient.

Practice has proved that Shanghai Sansi these LED black technology products conquered the limit of natural conditions, the perfect lighting of this super project, composes the Hong Kong, Zhuhai and Macao legend of light and shadow.——LED Bridge lighting

On August 23, 2017, super typhoon "Tianpigeon" ravaged Zhuhai; three days later, typhoon "Paka" passed through strongly; on September 16, 2018, this year's strongest typhoon "mangosteen" landed. However, the Hong Kong-Zhuhai-Macao Bridge and the bridge's LED lighting, LED information board intact, safe and stable through a severe test.——LED Bridge lighting

The bridge after installation of lamps has experienced many strong typhoons.

The LED products of Shanghai Sansi fully take into account the harsh marine salt spray, vibration, large temperature difference, ultraviolet radiation, typhoon thunderstorm and other adverse environments of the Hongkong-Zhuhai-Macao Bridge. They have stable performance, good performance and excellent quality.——LED Bridge lighting
