Dalian Semiconductor Lighting Industry Status Analysis

The reporter learned yesterday that Dalian Luming Group's "silicate phosphor" series of patents have been successfully authorized in the United States, Europe and Taiwan. As the world's largest LED sealing industry, China's entire industry has been subject to human control. Lu Ming's patent authorization made China's LED fluorescent powder production breakthrough the international patent blockade and monopoly, greatly reducing the production cost of white LED, and improving the international competitiveness of China's semiconductor lighting industry. Since the advent of white LEDs, two different fluorescent materials systems have been used internationally. Their patent rights are controlled by Japanese and German companies. Chinese enterprises not only purchase fluorescent materials, but also pay patent owners royalties. To allocate 10% of the profits to the patent owner, the production cost of the product will increase by about 70%.

In 2011, Dalian Golden Three-dimensional Technology Co., Ltd.'s high-power LED lamps beat more than 50 companies from the United States, Japan and other countries and regions to enter the US market. High-power LED lights have a bright future in the global market, but there has been a major dilemma, that is, heat dissipation. Dalian Golden 3D successfully solved this technical problem with its internationally advanced new heat dissipation technology with independent intellectual property rights. This year, the company's high-power LEDs have not only become very popular in the US market, but also gradually opened up in the Australian and European markets. As of now, sales this year have nearly quadrupled from last year.

Dalian Luming and Jin 3D have become the best microcosm of the development of the semiconductor lighting industry in Dalian. In recent years, Dalian City has given priority to the development of semiconductor lighting as a key area for cultivating strategic emerging industries and developing green economy. In April 2004, it was approved by the Ministry of Science and Technology as the first batch of “National Semiconductor Lighting Engineering Industrialization Bases” and became the Ministry of Science and Technology in 2009. Ten cities and ten thousand "Semiconductor Lighting Application Engineering Pilot City.

In order to develop the semiconductor lighting industry, Dalian has established a major project, and the semiconductor lighting R&D center and inspection service platform have also undergone a process from scratch and from weak to strong. At the same time, the establishment of the Semiconductor Lighting Research, Production and Research Alliance has provided the semiconductor industry with stronger technical support. Dalian City also actively promotes the construction of the semiconductor lighting industry core area, pays attention to building a complete industrial chain, and integrates the innovation resources of the middle and lower reaches of the industrial chain, resulting in an agglomeration effect.

At present, Dalian has formed a relatively complete industrial chain from substrate raw material production, epitaxial wafer manufacturing, chip production, device packaging to high-end applications. The entire industry chain is in a good development trend that is compatible with basic research and application development, and the upstream, middle, and downstream industrial chains are linked to each other.

After several years of key support, a group of key enterprises such as Dalian Luming, Great Wall Optoelectronics, and three-dimensional heat transfer emerged. At present, the cluster development of these enterprises has begun to take shape. In the upstream of the industry, advanced technologies such as high-purity ammonia and MO source of Dalian Guangming Chemical Design and Research Institute have taken the leading position in the country; Meiming epitaxial wafers have reached an annual production capacity of 300,000 wafers and 6 billion chips. In the middle reaches of the industry, Taiwan Chips, BDO Runda and other companies have established chip production bases in the city. In the downstream of the industry, Jiafeng Electronics has successfully developed an automatic loading machine to fill the domestic gap; Great Wall Optoelectronics “Century Great Wall” display won the bid for the Olympic Games and the World Expo; the high-power LED street lamp developed by 3D heat transfer also successfully penetrated into North America. market.
