Abstract: in December 2008, China's National Development and Reform Commission, in order to accelerate energy conservation, the phasing out of incandescent light, speed up the promotion of energy-saving lamps, Development and Reform Commission has launched the "China to phase out incandescent light, speed up the action plan to promote energy-saving lamps." preparation, further implementation of energy conservation.
Lighting was developed in the 1990s, a new generation of cold light source, with traditional light unparalleled advantages: saving energy and protecting the environment (no mercury and other harmful substances), long life (50,000 hours), reduce maintenance costs, provide better lighting quality and improved lighting visual effects and safety, these are the LED technology is increasingly used in many infrastructure construction.
Modern human civilization caused by the energy crisis warns us: energy saving urgency, the need for the development and utilization of resources for sustainable development. Since 2003, most of the country suffered a new round of power shortages. Power shortage situation contributed to the development of electricity, but it also led us to think of alternative energy and new energy.
China's current energy mainly from power generation, and power generation using oil and coal, due to soaring oil prices continue to result in increased cost of electricity, and coal burning will produce large amounts of carbon dioxide caused by the greenhouse effect. In order to solve the energy problem, China started mainly in two directions: the development of new energy and energy conservation, alternative target to 2010-2012 energy will provide 15% -30% of the energy needs, and our lighting energy consumption accounts for the total electricity consumption of 1/6, 1/3, such as incandescent lamps currently being replaced by LED, a year that the country could save an annual generating capacity of the Three Gorges Project.
