The development path of the lighting industry in mainland China was studied in this work. Lighting electricity accounts for about 12% of social electricity consumption in mainland China, while only approximately 15% of electricity is conversed into light when incandescent light bulbs are used. To reduce electrical energy consumption and mercury emission from coal burning in the lighting industry, China worked out a roadmap to replace incandescent light bulbs with energy-saving fluorescent lamps (FLs). However, FL products utilize mercury to give out light and release mercury in their production, consumption and disposal processes. Therefore, the challenges of the lighting industry that mainland China are facing are controlling mercury pollution through the environmentally-friendly producing of fluorescent lamps, effective collecting and treating of spent fluorescent lamps. It was proposed that to effectively reduce energy consumption and mercury pollution, a good way to do this is developing energy-saving and mercury-free light emitting diode lighting industry. The mainland China Government's strategies to develop lighting industry are worthy of consideration and emulation by other countries.
本工作研究了中国大陆照明行业的发展道路。照明用电约占中国大陆社会用电量的 12%，而白炽灯泡的电光转换率仅为 15%左右。为了减少照明行业用电和燃煤汞排放，中国制定了淘汰白炽灯路线图，用节能灯（FL）替代白炽灯。但是，FL 产品在生产、使用和废弃过程中利用汞发光，释放汞。因此，中国大陆照明行业面临的挑战是通过荧光灯的环保生产，有效收集和处理废旧荧光灯，控制汞污染。提出要有效降低能源消耗和汞污染，发展节能环保的发光二极管照明产业是一种很好的方法。中国大陆政府发展照明产业的策略值得其他国家借鉴。
