OSRAM's OSLON SSL LEDs Outline the Profile of Asian Games Stadium
Nov 12, 2010 The opening and closing ceremonies of the Guangzhou Asian Games will be held in a newly constructed half-stadium in Haixinsha Square. OSRAM Opto Semiconductors’ OSLON SSL LEDs were chosen to light up the exterior of the venue. These LEDs were used to produce a variety of colours, highlighting the gill-like side openings of the half-stadium, flanked by the city’s UFO-like opera house and the latticed Guangzhou TV Tower.
OSLON SSL amber/green/blue LEDs and warm white LEDs were used in separate flood lights to provide the different combinations of colours for the architectural lighting. Each floodlight was equipped with four independent sections of display pixels and colour adjustments, rendering bright and rich colours. Together with real-time video control system, different colours could be created to work with the requirements of the various opening ceremony programmes.
Around 200,000 LEDs were used in 3,200 floodlights in the project. To achieve the effect and efficiency required, several design options were explored.
OSRAM’s OSLON SSL series is a family of compact and symmetrical LEDs with a high efficiency of up to 84lm/W (typical) at an operating current of 350mA and a viewing angle of 80° or 150°. These LEDs are particularly suitable for architectural lighting.
