Zhongzhao Lighting Award Lighting Engineering Design Award (outdoor/block, single) third prize Project Name: Tianjin Cultural Center Grand Theatre Landscape Lighting Project Reporting unit: Tianjin Huacai Electronic Technology Engineering Group Co., Ltd. Project Description Tianjin Cultural Center is a municipal administrative and cultural center located in Hexi District. It is designed to cover the entire area north of Youyi Road, west of Longchang Road and north of Pingjiang Road. It covers an area of ​​about 900,000 square meters and contains museums. , library, art gallery, Tianjin Grand Theatre, Youth Activity Center Galaxy Shopping Center, etc. Tianjin Tianjin Cultural Center Grand Theatre has a total construction area of ​​100,000 square meters. It has a basement level of four floors and seven floors. The Grand Theatre roof is 235 meters long and 160 meters wide. It has three main truss roofs. Theater, variety theater, concert hall and small theater. The Grand Theatre is built on the waterfront and has a hydrophilic platform that provides more space for the public. The Grand Theatre was officially opened on April 28, 2012. The architectural design of the Tianjin Grand Theatre was conceived as “urban stageâ€. The Grand Theatre faces the lake and uses hydrophilic steps to create a spacious public space that forms an open urban stage that allows the public to rest, view, communicate, and meet the needs of outdoor multi-purpose performances. The architectural style of the Grand Theatre has well handled the relationship with the surrounding architectural forms and played a leading role in the cultural center. The use of transparent techniques and hydrophilic steps strengthen the connection between the east and west of the cultural center, expand the space for citizens' activities, and enhance the urban function of the building. The interior space is compact and convenient, and the functions are reasonable. The three theaters can be used independently for easy operation and management. The building is well coordinated with the surrounding environment. The design concept reflects the traditional Chinese cultural thoughts. The architectural form is simple and harmonious, harmonious and round, and the Grand Theatre will become an urban and open art palace. Innovations in lighting design concepts, methods, etc.: Tianjin Grand Theatre engineering design concept: - - Lighting the outdoor platform and large steps by using a large roof - - Extend the overall image of the building with integrated lighting, especially the shape of the roof - - Create a festive lighting effect that matches the importance of the building - - Avoid re-existing lampposts on outdoor platforms - - Emphasize the transparency of the night glass curtain wall Tianjin Grand Theatre engineering design goals: - - Contouring and complementing the visual appearance of the building at night - - Buildings as the main character, lighting to set off the environment effect - - Create a comfortable, safe night light environment - - Consider economic and ecological factors - - Avoid light pollution and excessively strong lighting effects to improve the quality of the space. Energy saving measures in lighting design: Energy-saving measures for landscape lighting in Grand Theatre -- The overall use of ABB's i-bus control system, all luminaires achieve unified program control. --The illuminating lamp under the ceiling of the Grand Theatre is designed according to different positions and needs. The lower illuminating lamp has 19 different powers and light distribution. -- The main lighting positions of the Grand Theatre, such as ceiling lighting roof lights, back grille lighting hook lights and top machine room curtain wall high tower lights, all adopt energy-saving and environmentally-friendly LED light sources. -- The roof lighting fixtures for the ceiling lighting of the Grand Theatre are level 3 dimmed according to different lighting modes, namely: 50%, 75% and full open control. The top machine room curtain wall high tower light group can be graded and dimmed according to different lighting modes. --The lighting fixtures of the back grille of the Grand Theatre can be used for energy saving purposes according to the different lighting modes under the control of the i-bus control system for 1/4, 1/8, 1/2, etc. And the power of the lamp is only 3W/m. What new technologies, new materials, new equipment, and new processes are used in the design: 1. Adopting new high-efficiency LED power-saving lighting fixtures designed and manufactured by the company. This new high-efficiency solid-state lighting technology replaces traditional lighting technology, reducing processing costs and difficulty, and luminaire efficiency is greater than 90%, greatly reducing the number of lamps. 2. Preferred materials, good anti-aging performance and light decay performance, low cost, energy saving and environmental protection, and low maintenance probability; 3. GPRS lighting energy-saving remote management system, used to detect the status information of each luminaire in real time, and control the lighting mode of each luminaire according to the control signaling of the remote monitoring center; 4. Integrate various types of energy-saving optimization technologies, and realize the maximum energy saving of the lighting system through intelligent control; 5. The main lamps such as roof lighting for ceiling lighting and hook lighting for back grille are concealed in the form of card. The lighting of the lamps is illuminated by the reflector and reflection principle. The light is soft and glare-free, and the lights are not visible. Combine architecture with lighting and fixtures. 6. All lighting pipelines are covered by dark coating so as not to affect the aesthetics of the building. What environmental safety measures are used in lighting design: 1. i-bus intelligent control system can carry out intelligent astronomical control, automatically adjust the astronomical control time, cater to the actual needs of urban landscape lighting, built-in power monitoring circuit that never crashes, to ensure smooth execution of the program. Energy saving, environmental protection, safety and reliability; 2. The LED light source is a semiconductor material that does not contain any harmful substances, so it is safe and environmentally friendly; the directivity of the LED light is highly utilized, reducing the diffusion of light and reducing the pollution of light; 3. The project integrates GPRS mobile network control technology, i-bus intelligent control system and control software, intelligent astronomical control technology and other intelligent control technologies to achieve maximum energy saving; 4. The selected luminaire has a high safety factor, requires less voltage and current, generates less heat, and does not pose a safety hazard. PUR cable is a type of cable that is specifically designed to withstand exposure to oil and other petroleum-based substances. The sheath of the cable is made from a material called polyurethane (PUR), which is known for its resistance to oil, chemicals, and abrasion. Oil Resistant PUR Sheathed Cable,Highly Resistant Against Wear Cable,Shielded Polyurethane Cable,Oil Resistant Cable Ruitian Cable CO.,LTD. , https://www.hbruitiancable.com
The oil resistance of this type of cable makes it ideal for use in industrial environments where there is a high risk of exposure to oil or other similar substances. It can be used in applications such as oil refineries, chemical plants, and automotive manufacturing facilities.
The PUR sheath also provides excellent mechanical protection, making the cable highly durable and resistant to damage from impacts or abrasion. This makes it suitable for use in harsh environments where the cable may be subjected to heavy use or rough handling.
In addition to its oil resistance, PUR sheathed cable often has other desirable properties such as flame resistance, UV resistance, and flexibility. These properties make it a versatile choice for a wide range of applications where durability and reliability are important.
Overall, PUR cable is a reliable and durable option for applications that require protection against oil and other petroleum-based substances. Its ability to withstand harsh environments and resist damage makes it a popular choice in various industries.
