WASHINGTON Dongguan Kingsun and Tsinghua University jointly developed a new breakthrough in LED lighting of urban roads the technical bottleneck, making the LED lights similar to the actual distribution of rectangular illumination, illumination distribution, the road than the current widespread use of integrated energy-saving high-pressure sodium lamp 60% or more.
According to reports, often using traditional high pressure sodium lamps, the existence of the uneven distribution of illumination, the illuminated object color distortion, glare serious, life is short, high maintenance and other shortcomings, the overall polishing efficiency is low. High luminous efficiency white LED, and has low production costs, device performance and stability, the market easy to accept, efficient, energy saving, long life, good color rendering index, etc., it is likely to become the first choice for the next generation of new street lights, however, Efficient production of power type LED lights facing the high optical and thermal technical barriers.
The current new lighting products have been successfully applied to the Guangdong Provincial Science Center and the Tsinghua University Gymnasium and the Tianjin Economic and Technological Development Zone and other road lighting project, and achieved good energy saving and lighting effects.
It is estimated that if the country's roads are high-efficiency lighting, new LED lights, could save 42 billion kWh of electricity, equivalent to saving 15.8 million tons of standard coal, close to several large production of coal a year. (Zhang Wen)
