Semiconductor lighting urgently needs to lighten the industry and reduce energy consumption

Street lamps and other functional lighting have significant energy-saving and emission-reduction effects, and breakthroughs such as “beyond lighting” have been achieved in agriculture and healthcare, and the implementation of typical demonstration applications such as the Olympics and World Expo has had a major impact in the world...

While many international companies with strong research and development strengths are competing for international discourse rights through mutual "patent licensing", China's semiconductor lighting industry is also deploying "collaborative innovation" with the "consortium" as its core.

Technology and Industrial Development

Enter the fast lane

At the beginning of the "10th Five-Year Plan", the Ministry of Science and Technology took the lead in supporting the development of semiconductor lighting technology and industry. In 2003, facing the revolution of lighting technology and the great potential of emerging industries, the Ministry of Science and Technology urgently initiated the National Semiconductor Lighting Project. Through the national science and technology plans such as the Science and Technology Tackling Plan, the 863 Plan, and the Science and Technology Support Plan, the semiconductor lighting technology innovation and industrial development have been continuously supported.

China's semiconductor lighting industry has grown from scratch, and has gradually grown and developed. Major breakthroughs have been made in key technologies that restrict industrial transformation and upgrading. The industry’s core technology R&D and innovation capabilities have rapidly improved, forming a more complete set of upstream epitaxial chips, midstream device packaging, and downstream integrated applications. Technological innovation chain and industrial chain with strong international market competitiveness.

As a strategic emerging industry in China, the semiconductor lighting industry is highly valued and supported at the national level. In 2009, in order to promote the healthy and orderly development of China's semiconductor lighting energy-saving industry and promote energy-saving and emission reduction, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Ministry of Finance, the Ministry of Housing and Urban-Rural Development, and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the “ The “Opinions on the Development of Semiconductor Lighting Energy-saving Industry” is planned from the national level and steadily improves the level of development of the semiconductor lighting industry.

At the same time, the Ministry of Science and Technology launched the “Ten City Million” pilot project for semiconductor lighting applications, and approved 37 pilot cities in the “Ten Cities and Ten Thousand Cities” in two batches to promote development and promote technology integration and innovative applications. Promote the formation of market mechanisms and business models.

Technology support

Industrial Development Foundation

At present, China has established a complete R&D system and has initially formed a relatively complete technological innovation chain from upstream epitaxial materials and chip preparation, midstream device packaging, and downstream integrated applications.

Under the continuous support of the National Science and Technology Plan, substantial cooperation was promoted between the upstream and downstream, and breakthroughs were made in some core and key technologies. In 2010, the luminous efficiency of China's industrialized high-power LED chips exceeded 100 lm/W, and the gap between the international advanced level was reduced to two to three years; the packaging reached the international advanced level; the first time in the world to launch Si-based LED with independent intellectual property rights The chip, the luminous efficiency exceeds 90 lm/W, has already realized the industrialization; In the next generation technology core aspect, our country and the international are on the same starting line, if the deep ultraviolet LED device research and development are in the international advanced level.

The number of patents applied for in the field of semiconductor lighting in China has risen rapidly in recent years. In 2010, China had 30,682 LED-related patent applications, which accounted for about 27% of the global LED patent applications. The average growth rate from 2001 to 2009 was 33%, which was significantly higher than The global average level, and the advantages of downstream applications for patent applications are significant, and applications account for about 76% of the total number of patents, of which functional lighting applications such as roads are in an internationally leading position.

Formation of dominant resonance

Innovative development model

The National Semiconductor Lighting Engineering R&D and Industry Alliance (CSA), under the strong support and guidance of the Ministry of Science and Technology, was initiated by the backbone enterprises and research institutes engaged in the semiconductor lighting industry in China in accordance with the principle of “voluntary, equal, and cooperative”. At present, it has grown to 272 member units, including mid-stream and downstream companies in the industry chain, well-known enterprises and research institutions from overseas.

Through extensive regional and international cooperation, the Alliance actively expands its international exchange and cooperation in semiconductor lighting standards, inspections, and applications, and continues to expand the breadth and depth of international exchange and cooperation in semiconductor lighting through projects, standards, and demonstrations.

In accelerating the construction of semiconductor lighting industry standard system, the alliance has made unremitting efforts. "As long as it is conducive to technological innovation and industrial development, we will fully promote." Said the deputy director of the National Standards Committee. At present, the street lamp and tunnel lamp technical specifications prepared by the alliance organization have been adopted by three ministries and commissions, and the technical specifications for downlights and spotlights have been established as four national standards. Future Alliance will also work with relevant industry authorities to strengthen the research on semiconductor lighting standard strategy and semiconductor lighting standard system and jointly promote the standardization process.

With the CSA as the main initiator, the Semiconductor Lighting Industry Organization of the United States, Australia, New Zealand, Holland, South Korea, India and Taiwan established the "International Semiconductor Lighting Alliance (ISA)" on October 16, 2010. At present, there are 8 associations and societies, 15 academic institutions and 31 companies among the 54 members of ISA, which are geographically distributed across Asia, Europe, North America, Australia and New Zealand.

"The industrial alliance has made fruitful work, strengthened the international competitiveness of China's semiconductor lighting industry, and won the right to speak internationally." Academician Shi Changxu said.

"The alliance has a very good feature, that is, it is very clear openness and internationalization." For the important role of the ISA International Alliance, Minister of Science and Technology Wan Gang pointed out that in the future we will further strengthen international cooperation on this basis.

At present, China’s ISA International Union, which takes the lead and holds the presidency, has made initial progress, including the establishment of an “International Standards Technical Committee” and the formulation of a “Blueprint for the Global Semiconductor Lighting Industry Development Plan”.

Experts said that China's LED lighting applications in the future have great market potential. It can be imagined that, as the world's most populous country and the country with the fastest economic development, the considerable market size and mature industrial base will bring about promising market development prospects for the development of China's LED lighting industry.

XLPE Insulated Al Alloy Interlocked Cable is kind of cable, in which the rare earth high compressed aluminum alloy is used as conductor, and PVC is used as Jacket wound around.
