Cihai Bridge and Ferris Wheel for the first full-body test light
Cihai Bridge and Ferris Wheel Daytime Effect Map
Cihai Bridge is located in the traditional historical and cultural area of ​​Tianjin and the birthplace of modern industry. It connects the source of the Haihe River to the Great Depression and the Canal Economic, Cultural and Business District. It is located in the Sancha River mouth of Hebei Province and Hongqiao District, across the Ziya River and connecting Hebei. District Wuma Road and Sanqiao Shiheng Street in Hongqiao District.
The combination of the Cihai Bridge and the bridge is simple and stylish. It has surpassed the British side of the Thames and is known as the world's largest eye of London. The total length is 330 meters and is divided into two layers. The upper floor is a motor vehicle-only road and the lower floor is a sidewalk bridge. The Cihai Bridge Ferris wheel has a diameter of 140 meters, which is equivalent to 35 stories. The wheel is equipped with 64 360-degree transparent suspended cockpits. Each cockpit can accommodate 8 people and can accommodate 512 people at the same time. The time required for the Ferris wheel to rotate one week is 30 minutes. When you reach the highest point, you can see the area within 40 kilometers. The surrounding scenery is unobstructed. Even when you are in the clear sky, you can even see Tianjin Port, which is a veritable eye of Tianjin.
As one of the 20 important projects of the people's heart project in Tianjin and one of the key construction projects of the Olympic Games, the Cihai Bridge project has been completed. Recently, the Cihai Bridge and the Ferris wheel carried out the first full-body test light, and the Haihe River under the night was even more dazzling. The contour lights of the huge roulette on the bridge and the reflection in the water form a two-ring appearance, attracting the attention of many past citizens.
The test light is part of the security inspection measures before the operation of the Ferris wheel. Under the organization of the relevant departments, the Tianjin Eye Ferris wheel was recently inspected by the National Special Equipment Inspection Center. The Ferris wheel is equipped with a servo system and a dual power supply system. The cockpit is equipped with fire extinguishers, lifelines, etc. In the event of a malfunction, visitors can walk down the rope to avoid danger. A walkie-talkie is also installed in the Ferris wheel. If a passenger has a sudden illness in the cockpit, the walkie-talkie can be connected to the ground console to adjust the transport speed so that the patient can quickly reach the ground.
According to reports, it is expected that the end of August, Cihai Bridge will be officially opened to traffic; before the opening of the Olympic Games, the eyes of Tianjin will turn. At that time, people will board the world's largest Ferris wheel, and enjoy the beautiful scenery along the Haihe River with the rotation of the giant wheel.
Cihai Bridge and Ferris wheel landscape lighting design draws on the successful cases at home and abroad, adopts a new lighting design concept, and focuses on portraying the overall structure of the bridge, rendering the silhouette of the Ferris wheel's herringbone frame, creating a creative contrast with the reflection in the water. The main light of the wheel bridge and the ambient light complement each other, transforming a fairytale beautiful night scene. The point strobe lights inside the cockpit of the Ferris wheel and the line contour lights on the wheel are all made of high-quality LED products, reflecting the purpose of green, energy saving and environmental protection.

Usually if the membrane switches need assembled many LEDs, then we suggest to use FPC circuit, it can get more stable LED soldering quality. For the normal application the PET circuit is enough, which is more economical. In addition if the conductor pitch is 0.5mm, although we also can print it, but we still suggest to use FPC circuit. Because of that 0.5mm pitch is too small and it is easy to occur the short circuit problem.
