At present, the demand for LED in all walks of life has increased significantly. As far as the Chinese market is concerned, with the introduction of technology and the enhancement of independent research and development, the national output of LED chips has been effectively improved in 2013, which is conducive to the development of the domestic industrial market.
At present, the domestic LED chip companies are geographically distributed, and the domestic and international extended chip industries are mainly concentrated in the Yangtze River Delta region, the Handan region and the Bohai Bay region. As many cities in the Yangtze River Delta region competed to launch the MOCVD subsidy policy, the number of LED chip companies grew rapidly in 2009-2012, and the upstream chip industry investment in Anhui, Zhejiang, Jiangsu, Shanghai and other places blossomed more and more, showing a hot development trend.
The multi-market centralized growth of the chip business accelerated the expansion of the capacity utilization rate of manufacturers based on lighting chips. Dehao Runda's LED chip revenue in 2012 was only 220 million yuan, and it is expected to reach 350 million in 2013, which will grow by more than 50%. Yuanrong Optoelectronics will double its revenue in 2013. Sanan Optoelectronics, Tongfang Optoelectronics and Hualei Optoelectronics have maintained a high level of capacity utilization.
Manufacturers based on display chips have increased their lighting chip business. Huacan Optoelectronics LED lighting chip revenue has gradually increased, and it is expected to reach 50% by the end of 2013; Silan Mingxin's new production machine is mainly used to produce lighting chips. In the case of the rise of local chip companies in mainland China, the market share of Taiwan and international manufacturers in the mainland is gradually shrinking. LEDinsde data shows that in 2013 China's LED chip country has reached 80.
Review 2013 Outlook 2014 Industry Development Prospects In 2013, China's LED chip industry concentration increased further. From the top five manufacturers' revenue market share, it increased from 61.9 in 2012 to 64.4. According to Jiuzheng Building Materials Network Xiaobian, with The industry continues to develop, the concentration will continue to increase, and industry reshuffle and integration will be inevitable. Yu Bin said that from the current chip industry situation, although the price decline rate has slowed down, but the profitability of enterprises is still difficult to upgrade, small and medium chip manufacturers lacking funds and technology will become the next batch of bankruptcy or mergers and acquisitions. Object. Looking forward to 2014, LED lighting is still the main area for chip manufacturers to compete in the slowdown of backlight and display. LEDinside expects global LED lighting output value to reach 17.8 billion US dollars in 2014, the total number of LED lighting products shipped to 1.32 billion, an increase of 68.
In terms of technology, the 4-inch epitaxial growth technology has been rapidly increased by the mainland manufacturers. In addition to the use of Dehao Runda 100, it is expected that the proportion of Sanan Optoelectronics, Huacan Optoelectronics and Guoxing Optoelectronics will also reach More than 30%; FlipChip will also be sought after, and it is widely used in high-power lighting and flashlights.
