Promote green lighting will significantly reduce carbon emissions

"By 2020, China's semiconductor lighting industry output size is expected to more than one trillion yuan, will greatly benefit the energy-saving and emission reduction." National Semiconductor Lighting Project R & D and Industry Alliance, Deputy Secretary-General RuanJun said.

Semiconductor (LED) lighting is also known as solid-state lighting, following the incandescent, fluorescent light another revolution. Statistics show that on average six hours a day to calculate lighting, a LED lighting compared with the same illumination of incandescent lamp, a year can save about 76.65 kwh of electricity, reduce carbon dioxide emissions by 107.3 kg, 26.83 kg of standard coal savings; and compared to the same fluorescent illumination, a year can save about 40 kwh of electricity, 42.75 kg of carbon dioxide emissions, saving 13.68 kg of standard coal.

It is because of energy saving, long life, widely used features, semiconductor lighting as an important area of energy-saving and environmental protection industry, is one of China's strategic emerging industries. In recent years, the lighting key technology and international level continued to narrow the gap between China's semiconductor, in the pursuit of high efficiency at the same time, LED lighting forward to the on-demand lighting.

Currently, in the LED lighting industry chain, each link of technical breakthrough and innovation is rapidly increasing. In terms of materials, new substrate material and technology progressed rapidly; in lighting applications, cost, reliability and light quality has been improved; in non-visual lighting, the research of the biotechnology, agriculture, medical treatment, uv LED rapid development; industrial research, combined with building materials and LED lighting has improved; intelligent lighting is the most attention in the field, the rapid development of technologies and applications.

Ruan Jun told reporters, with the breakthrough technology, the emerging energy-saving effect and continue to expand the industrial scale, and applications continue to expand, the semiconductor lighting industry in China's lighting industry has established a dominant position, and entered a critical period of development .

2015, China's semiconductor lighting industry as a whole will reach more than 4,200 one hundred million yuan, the scale from 350.7 billion yuan in 2014 increased by 21%, keep the high-speed growth. Among them, the epitaxial silicon size of about 15 billion yuan, the package size of about 60 billion yuan, the scale of the downstream applications rose to 340 billion yuan. At the same time, semiconductor lighting industry in energy savings and reduce greenhouse gas emissions intensity has also made remarkable achievements. 2015, LED functional lighting market penetration rate of 30%, saving 100 billion kwh, and reduce the more than 9000 ten thousand tons of carbon dioxide.

RuanJun analysis said, because the LED light source is electronics, especially suitable for combined with automatic control and sensing technology, the development of intelligent lighting, at the same time of individuation, comfortable, safe and efficient, can further through the system of management to achieve something greater than itself of lamps and secondary energy saving effect (can be energy-saving 30%), therefore, intelligent lighting to replace traditional lighting is the inevitable trend of the future lighting industry development. It will also make the LED lighting has play a more important role in promoting energy conservation and emissions reduction.

According to the National Lighting R & D and Industry Alliance predicts that by 2020, China's semiconductor lighting industry market penetration rate of 70%, the annual saving 340 billion kwh, the Three Gorges Hydropower 2014 annual generating capacity of 3.4 times.
