Due to various factors, LED chip, packaging, and application prices have continued to fall since the beginning of the year, with an average decline of more than 20% in the first seven months. Concerns about excess production capacity have become the most concerned topic among entrepreneurs, and serious investment overheating in the LED industry chain has emerged.
Sapphire substrate investment is the most overheated
“Since the beginning of the year, the LR Escorts price of LED chips has dropped by more than 20% “The growth of the application market is smaller than expected, and many companies are under huge pressure to ship, and chips are almost sold by the pound.” An LED chip manufacturer told reporters yesterday that sadly, this is just the beginning.
According to statistics from the Gaogong LED Industry Research Institute, from January to July this year, the price of 2-inch sapphire substrates dropped from a maximum of US$35/piece at the beginning of the year to US$13-15/piece at present, with an average decline of more than 50%; the average price reduction of LED chips is 25%, with the maximum price reduction reaching 42%; LEDThe average price reduction for packaging is 23%, with the maximum price reduction reaching 37%; the average price reduction for LED applications also reaches 21%.
“The overheating of investment in LED sapphire substrates is the most serious, followed by internal chips, packaging production capacity is absolutely redundant, and the overall performance of LED applications is good.” Zhang Xiaofei pointed out that under the competitive promotion of preferential subsidy policies by local governments, from 1 to 7 in 2011 In September, the number of MOCVD units in mainland China increased by more than 200. It is estimated that by 2012, LED chip production capacity will reach 10 times that of 2010.
According to statistics, the total planned investment in LED internal chips in mainland China is currently 183.5 billion, of which 73.5 billion are planned for projects under construction; the total planned MOCVD equipment scale is 4,519 units, and 1,642 units are planned for projects under construction. The number of units owned is 543. Since last year, local governments such as Yangzhou and Wuhu have subsidized MOCVD equipment on a large scale to expand the scale of the LED chip industry; however, at the same time, the growth rate of the application market has been unsatisfactory.
In the application aspect, backlight has always been regarded as an important driving force in promoting LED applications, but panel manufacturers have lowered their shipment plans in the past two quarters. Some senior analysts believe that due to the high inventory and slow sales of LED backlight TVs in the fourth quarter of 2010, the first quarter of 2011, and the early second quarter, the LED backlight market demand has therefore decreased.
China’s largest manufacturers also face the same problem. According to Zhan Yiren, secretary-general of the National Optoelectronic Semiconductor Industry Association, the industry boom driven by LED backlight TVs in previous years has not continued this year; if the backlight cannot support production capacity, it is hoped that lighting can drive it; but judging from the current situation, It also needs the prices of LED lighting products to be more competitive, or the government to issue corresponding policy incentives to effectively awaken this market.
“With the release of production capacity in the second half of the year, companies will face more serious price challenges, and short-term overcapacity is inevitable.” Gong Weibin, chairman of Ruifeng Optoelectronics (300241, Stock Bar), said.
The pros and cons of “price war” coexist
It is widely believed in the industry that price wars will accelerate the reshuffle of the industry, eliminate some small and medium-sized enterprises, and concentrate more market share on leading companies. This is more obvious in the packaging process.
According to Zhang Xiaofei, the number of openings of LED packaging companies this year has been significantly higher than this year, the number of new companies has significantly decreased, and the gross profit margin of most LED packaging companies has dropped significantly, and the total investment has dropped by 20% compared with 2010. %above. “LED packaging companies have the lowest risk resistance. Compared with the profits of more than 90% of LED packaging companies in 2010, the proportion of loss-making companies will increase significantly this year; in addition, it is expected that 10% of companies will be forced to close down.” He said.
In LED investment, some companies have been more cautious. Wang Lianghai, vice president of Tongfang Shares (600100, stock bar), told reporters that Tongfang’s current investment in the LED field is LR Escorts will account for more than 20% of the assets, and will decide whether to increase capital in the future depending on market conditions; at the same time, the company is also considering the overall layout of the industrial chain.
But Gong Weibin believes that , price competition is a very suitable era for enterprises to express differentiation. “Price war is conducive to the emergence of two types of LED manufacturing companies with core capabilities, one is technology-leading; the other is cost-leading.” “He said that in this regard, Ruifeng Optoelectronics will pay more attention to reducing costs through technology and strive to reduce explicit costs by 30-50% without reducing product quality.
He also pointed out that in addition, On the one hand, the decline in LED prices has also promoted the expansion of the market, which will prompt LEDs to enter the application lighting market faster.
Team up to gain popularity and win in chaos
Analysts from Industrial Securities pointed out that in LED chips. In the context of oversupply, we are more optimistic about the lower reaches of the industrial chain, especially the future general lighting market. According to the latest data from DisplaySearch, LED backlight demand will reach its peak in 2013, and then demand will shift to lighting. It is estimated that lighting LED applications will be in 2011. Volume will be 20% higher than in 2010.
Data from the Gaogong LED Industry Research Institute also pointed out that although the gross profit margin of LED application companies has declined, the overall production scale has grown rapidly, especially the landscape. Lighting and general lighting products. “Thanks to the increase in sales scale, the overall profit situation is better than that in 2010, and the proportion of unprofitable enterprises will be significantly reduced. “Zhang Xiaofei said.
He Kaijun, director of Xiamen LED Promotion Center, pointed out that under the current market situation, companies must quickly respond to the high growth of the market. There is no future for working alone, and they must integrate resources to form synergies. Ruifeng Optoelectronics, Zhejiang Sunshine and other companies said when attending yesterday’s forum that they have reached agreements on the establishment of patent pools and joint talent cooperation.
“For chip companies, buy less MOCVD equipment and invest more in China. Downstream companies forming an alliance that connects the upper, middle and lower reaches may be the best choice now. “Zhang Xiaofei said.
Is energy storage redundant? Some semiconductor components are in oversupply, and some key components of the energy storage system are still in oversupply. Energy storage It’s just a long-term phenomenon.

Is the power battery about to enter the redundancy period? In the manufacturing sector, overcapacity is the norm in the market, but absolute redundancy or large amounts of redundancy will cause serious problems. At present, the risk of excess domestic power battery production capacity has emerged, and demand has attracted great attention in the industry.
