Professor Sun Qingcheng from the Department of Optoelectronics said that the lighting should not be dazzling and the floor should be bright enough. This is a dilemma in the design of the luminaire. The team has accumulated more than ten years of optical experience and successfully overcome this obstacle. Under the total power consumption, In one breath, the illumination of the stadium is increased from less than 150 LUX to 450 LUX.
Professor Sun Qingcheng said that the key technology lies in the design of the light distribution curve of the LED and the photon circulation technology of the light box. The unique and beautiful hexagonal light box design has large illuminating surface and uniform illumination. It is especially suitable for indoor venues with strict glare requirements. This design requires reliability, and the heat dissipation design and waterproof design are extremely strict. More than ten times the fluorescent light box, the power consumption is 40% of the traditional fluorescent light box, which can achieve true environmental protection and energy saving. 
At the end of January, the high-tech and high-performance LED lighting of the Central University of Taiwan Badminton Hall was officially launched. Sun Qingcheng's carefully designed hexagonal light box with patented anti-glare design is environmentally friendly and energy-saving, creating a bright and comfortable sports environment. CUHK is promoting another practice on the green campus.
