The opening and closing ceremonies of the Guangzhou Asian Games (scheduled for opening on November 12th) will be held at the newly built Haixinsha Square. The OSLON SSL LED from OSRAM Opto Semiconductors was selected as the illumination source for the exterior of the venue. These LEDs show different colors, highlighting the shape of the stadium's side-shaped opening, the two wings are the UFO-like Guangzhou Theater and the grid-like Guangzhou TV Tower.
OSLON SSL Amber/Green/Blue LEDs and Warm White LEDs will be used for stand-alone floodlighting, providing a variety of color combinations for architectural lighting. Each floodlight is equipped with four separate display pixels and color adjustment areas to produce bright, rich colors. It will be paired with a real-time video control system to create colorful colors based on the various needs of the opening ceremony.
The project uses a total of 3,200 floodlights with approximately 200,000 LEDs. In order to achieve the desired results and performance, a variety of design solutions have been explored before. Chen Jiansheng, general manager of Guangzhou Zhongda Zhongming Technology Co., Ltd., responsible for the design of these floodlight optics and control systems, said: "After testing and comparison of various design schemes, a special two-way asymmetric lens design and DMX network system were selected. In this way, the system is simpler and the lighting effect is more attractive."
OSRAM's OSLON SSL series are compact, symmetrical LEDs with luminous efficiencies as high as 84 lm/W (typ) at 350 mA operating current and 80° or 150° viewing angles, making them ideal for architectural lighting applications. Zhong Jiecong, Marketing Director, Asia Pacific, OSRAM Opto Semiconductors Asia Ltd. said: "Osram's OSLON SSL LED can be part of the opening ceremony of the Asian Games. We are very excited. Millions of visitors and TV viewers will see these amber and blue. Green and warm white LEDs add a beautiful color to the look of the stadium."
The Asian Games will be held from November 12th to 27th, with 11,700 athletes from 45 countries competing in 42 venues. The opening ceremony will be broadcast to Asian countries and other countries, which will be the best stage to prove the advantages of LED architectural lighting.
At present, architectural lighting is the largest application area for solid-state lighting. According to the forecast of the US market research firm Strategies Unlimited, the architectural lighting sector accounts for 33.7% of the overall solid-state lighting market. As of 2014, the compound annual growth rate will reach 16%.
Millions of tens of millions of guests and spectators will experience the magnificence of LED architectural lighting at the opening ceremony of the Asian Games Stadium.
