Shanghai east silver center solar lighting renovation project

General information of the project: the construction units: Shanghai loose ears lighting engineering co. , LTD. LED light tubes and light control system integration suppliers: the sea ray luen lighting technology co. , LTD. : Shanghai east silver center lighting renovation project: wu jianzhong, Huang Zezhun, Deng Ji China telephone: 021 - 62847339 url: WWW. gld。 Cn email: sales @ GLDS. Cn completion date: on April 25, 2010, environmental background:

Shanghai east silver center Shanghai east silver center, located in hongqiao central business zone, to join hands in the world's best-known CENSLER design firm with the Shanghai modern architectural design group, build classic form - business building - Gemini. Contracted and contemporary building, elegant atmosphere, a fusion of Chinese and western design elements, through the environmental protection and energy saving ideas. Transformation content: demolition of 08 to install normally on white leds, replacement for can appear by changing the LED digital tube light. Lighting control system can realize coordination twin towers building lighting changes. Design and installation of lamps and lanterns: according to the characteristics of the east silver center building, lamps and lanterns is installed in a building at the top of the outer convex of the outer edge of the vertical glass grid, the thickness of the glass grating of 26 mm, the concealment of the lamps and lanterns day into consideration, we special choice on sea ray ZD30 series light tube lamps and lanterns of lighting, through the special design of metal trough, hide all the lamps and lanterns is the power cord, signal lines, including joint online inside groove, the surface clean.

glow LED lamps and lanterns of line 28 mm in diameter, according to characteristics of building size, lamps and lanterns is specially designed for 1150 mm long/root, joint configuration 64 white triad patch inside the lamp light source, lamps and lanterns of each can is divided into eight independent control unit, lamps and lanterns USES external high power factor of switching power supply quality, cosФ≥0. 93). Centralized power supply, peak power of 18 w per meter. Lighting control system: USES the sea ray CK3000 lighting control system, on the basis of traditional DMX512 protocol, the plane full-color images combined with control technology and integration, the signal control of the bus system is stable, reliable performance, give full play to a single set of lamps and lanterns of signal failure will not affect the normal work of the other lamps and lanterns, greatly improve the stability of the system daily work performance. Technical characteristics of the project: the project technical difficulty lies in the following three points: ( 1) White LED infinite driver; White LED is on the surface of blue LED chip, silver powder coating membrane, the secondary excitation eventually emit white light, in white lamp normally on state, almost invisible to the naked eye light flashing, but changes in conventional technology with gray scale control, there will be light light flickering. The sea ray league special research and development on the white light LED the infinite drive technology, has realized continuous, soft white LED free change. （ 2) Diameter of less than 30 mm light pipe protection grade hard IP65 lamps and lanterns; Soft light tube waterproof and dustproof technology is always a difficult problem to the field, on the sea ray has been focused on the structure of itself of lamps and lanterns is waterproof, does not agree with the shell of lamps and lanterns can't effectively under the condition of waterproof and dustproof, LED directly to the circuit board glue sealing, allow dust and rain water in and out of the inner cavity of lamps and lanterns, but still keep the normal work of the passive state of waterproof. Scientific structural design not only ensures the lamps and lanterns of long-term to maintain normal work, and make full use of the self-cleaning function of PC surface rain, in the selection of low light failure cases, LED lamps and lanterns is in 3 - 5 years or even longer period of time can keep good luminous effect. （ 3) Gemini 8 facade is difficult to realize synchronous coordination control changes; East silver Gemini because only the skirt building in the center of the part is mutually, therefore, the lamps and lanterns of two buildings and the distance between the control computer is far apart, in the process of signal transmission over long distances, external disturbance and the attenuation of the signal itself is important factor affecting the normal system performance, the sea ray league through the optical fiber transmission technology and the integration of local area network, perfect solves the technical problems of the system integration control. Shanghai east silver center is upgraded, the twin towers building normally on eight vertical outline of white, the top eight of the facade can implement the coordinate change of lighting control, performance, 2010 Shanghai world EXPO mascot haibao and EXPO and various graphic effects, will create a changeable facade lighting stage, with the demand of large-scale activities, deduce various environmental art.
