半导体照明产业是迎合全球节能需要而发展起来的一个新兴的高技术产业。它是用第三代半导体材料制作光源和显示器件,是一种新型固态冷光源。它包括外延芯片、封装及下游应用,耗电量仅为传统白炽灯的1/10、节能荧光灯的1/3,且寿命可延长数十倍。据估算,如果将全国1/3的传统照明灯改用LED,每年节电量相当于一个三峡电厂的总发电量。我国2010年LED产业产值约为1500亿,就业人员近百万。 Semiconductor lighting industry is to meet the global energy needs and developed a new high-tech industries. It is the third generation of semiconductor materials, light sources and display devices, is a new type of solid cold light source. It includes epitaxial chips, packages and downstream applications that consume only 1/10 the power of traditional incandescent bulbs and 1/3 of energy-saving fluorescent lamps, and extend the life expectancy by tens of times. It is estimated that if 1/3 of the traditional lighting in the country is switched to LED, the annual electricity saving is equivalent to the total power generation of a Three Gorges power plant. China’s LED industry in 2010 output value of about 150 billion, employing nearly 1 million.
