Encapsulation of LED devices in the development of semiconductor lighting industry plays a role of connecting link between the preceding and the following and China in the global semiconductor lighting industrial chain division of labor has scale advantages and cost advantages of one of the aspects of the industry.

It is understood that China is a big country of production and consumption of incandescent lamps, China's lighting electricity consumption accounted for about 13% of the country, if the use of all 1400000000 incandescent lamp, energy-saving lamps can save 48000000 kwh per year, equivalent to 48000000000 tons of carbon dioxide emissions, the energy saving potential.
