"By 2020, China"s semiconductor industry output value is expected to exceed one trillion yuan, will be greatly conducive to energy-saving emission reduction." National semiconductor lighting engineering research and development and Industry Alliance executive vice secretary general Ruan Jun said.

Semiconductor (LED) lighting is also known as solid-state lighting, is the following incandescent, fluorescent lamp and a light source revolution. Statistics show that by the average of 6 hours per day lighting calculations, a LED lamp with the same illumination of incandescent lamp, a year can save electricity about 76.65 kwh, reduce carbon dioxide emissions 107.3 kg, 26.83 kg of coal; compared with the same fluorescent lamp, a year can save electricity about 40 kwh, carbon dioxide emissions 42.75 kg, 13.68 kg of coal.

Because of the characteristics of energy saving, environmental protection, long life and wide application, semiconductor lighting is an important field of energy saving and environmental protection industry, and it is one of China"s strategic emerging industries. In recent years, China"s semiconductor lighting key technology gap with the international level is becoming smaller and smaller, in the pursuit of high efficiency at the same time, LED lighting by alternative to on-demand lighting and beyond lighting forward.

At present, the whole LED lighting industry chain in different aspects of technological breakthroughs and technological innovation is rapidly improving. In terms of material, new material and technology progress rapidly. In lighting applications, to enhance the product"s cost, reliability and optical quality of innovation is more concentrated; in the non visual lighting, biological, agricultural, medical, ultraviolet LED research rapid development; in the production of research, building materials and the combination of LED lighting, intelligent lighting is currently the most attention, technology and application development.

Ruan Jun told reporters, with the continuous breakthrough in technology, energy saving effect, the continuous expansion of the scale of the industry and the continuous expansion of the application field, semiconductor lighting industry in China"s lighting industry has established a leading position, and enter the critical period of development.

2015, the overall size of China"s semiconductor lighting industry will reach 4245 yuan, compared with 2014"s 3507 yuan of 21% yuan, to maintain rapid growth. Among them, the upstream epitaxial chip size of about 151 yuan, the size of the middle reaches of the package is about 615 yuan, the downstream application size is up to 3479 yuan.

At the same time, the semiconductor lighting industry has achieved remarkable results in saving energy, reducing greenhouse gas emissions and so on. 2015, LED functional lighting market penetration rate of 30%, saving 1000 kwh, about 90000000 tons of carbon dioxide emissions.

During the period of 45 global response to the energy crisis, the deterioration of the environment, the challenge of the aging of the population, especially our country enters the new economic norm, in the process of economic growth is shifting, structural adjustment and industrial upgrading, to the semiconductor lighting provides more vast development needs and opportunities.

From the perspective of industrial development, the LED lighting industry is transforming from the efficiency and technology driven to the cost / market driven. In the new stage of development, LED lighting will become more efficient, more energy-efficient, more environmentally friendly, intelligent, digital and networked lighting.

As the LED light source is an electronic device, it is especially suitable for combining with automatic control and sensing technology. The development of intelligent lighting, which is achieved by the system management, can achieve two times more energy saving (30%), and therefore, it is necessary to replace the traditional lighting. This will also enable LED lighting to play a greater role in promoting energy-saving emission reduction.

According to the national semiconductor lighting engineering research and industry alliance predicted that by 2020, China"s semiconductor lighting industry, the market penetration rate of 70%, festival electric 340 billion kwh is 3.4 times the 2014, the annual generating capacity of the Three Gorges hydropower station.
