Led by leaps and bounds, LED technology has gradually replaced high loss tungsten filament lamps and mercury fluorescent lamps, which are widely used in various lighting applications.
Hong Kong Department of electrical and electronic engineering professor Xu Shuyuan and the team, engaged in the study of sustainable development of lighting technology, the development of a new generation of Gao Guangxiao, high efficiency, long life and recyclable LED lighting system, can make the lamp of life by three years to ten years, drive 85% materials can be recycled, first apply now in Guangdong city of Heshan Province, is also working with the Zhongshan City consultation installation plan.
Xu Shuyuan led the team, in addition to the Hong Kong Polytechnic University, and even a German University of science and technology, developed the world's first "unified theory" for the first time with the light of thermoelectric, light, heat, electricity and color four elements interaction, can adjust the LED lighting brightness and color temperature accurately, reduce indoor lighting due to temperature changes or LED light aging and inconsistent. In Hong Kong, a system was invented to control the light dark and color temperature of LED bulbs with a smart phone.
In addition, Hong Kong earlier the same theory is applied to the research and development of new driver based on the LED energy saving lamps, street life from three years to more than 10 years, more than 80% of the material can be recycled, helps to reduce the toxic waste discarded semiconductor and liquid electrolytic capacitor, and can be used for safe use of environmental temperature and frequent lightning.
