Prices continue to fall, and the trend of the larger Evergrande is spreading in product prices. Although the LED lighting market has grown rapidly in 2014, the price of LED chips is expected to continue to fall due to the strong expansion of large factories in China and South Korea. In fact, the price of 6-watt LED bulbs has dropped from 40 dollars to 20 dollars in the past two years, and then to 10 dollars. It seems that the price reduction trend has not stopped yet. It is estimated that the average selling unit price (ASP) of LED chips in 2014 may still Maintain a decline of about 10%. Li Bingjie, chairman of Taiwan's LED chip maker Jingyuan Optoelectronics Co., Ltd. pointed out that the average selling price of LED chips will still drop by more than 10% every year. At the same time, he believes that chip demand will not reach the balance of supply and demand until the second half of 2014.
Due to fierce price competition, the industrial ecology will change accordingly. It is predicted that in the next two years, Taiwan's LED industry will continue to have horizontal or vertical integration and mergers and acquisitions. This also means that in addition to the integration between the upstream and downstream supply chain links, integration within the same industry will also occur. Li Bingjie even believes that the next two years will be the key period for the development of LED chip manufacturers and packaging manufacturers. The LED industry in Taiwan will complete the integration and mergers and acquisitions between enterprises by 2015. At that time, there will probably be only two remaining in Taiwan. The chip makers around. In response to this development trend, Jingyuan Optoelectronics has prepared sufficient funds to carry out vertical integration plans such as investment, shareholding and cooperation. However, Jingyuan Optoelectronics is not optimistic about LED one-stop operation mode, so it mainly adopts virtual The way to integrate it.
Actively develop HVLED and unpackaged LEDs
In the face of price pressure, LED chip manufacturers can only respond to reduce the production cost of products, and seek breakthroughs in product design and manufacturing processes. In addition, to make more efficient LEDs with the least amount of materials, it is also the main method to reduce costs. one. To this end, package-free chips and high-voltage (HV) LEDs are expected to become the two major product development trends in the future. In terms of HVLED, the use of an IC can replace the power driver, making the chip occupy 30% of the total cost of the LED bulb. Dropped to 20.
Jingyuan Optoelectronics has been focusing on the research and development of high-voltage LED chips. In fact, as early as 2010, high-voltage LED products have been published, which have the advantages of small area, good heat dissipation capability and reduced drive cost. After long-term market cultivation, Jingyuan Optoelectronics' high-voltage LED has been widely used in street lamps, lamps and other products, and has become an important supplier of high-voltage LEDs in the LED chip industry in Asia. The products have high luminous efficiency and patents. Protection technology and huge red LED capacity support advantages, therefore, some research institutions pointed out that Epistar will be one of the major beneficiaries of the global LED lighting business opportunities.
In addition, in recent years, Jingyuan Optoelectronics has established a number of joint ventures in the Chinese mainland market, such as Xiamen Development Crystal Lighting Co., Ltd., which is a joint venture with China Electronic Information Industry Group (CEC), and a joint venture with Guangbao Technology and China Color Power Plant Konka. Changzhou Jingpin Optoelectronics, Shandong Guanquan Optoelectronics Co., Ltd., which is a joint venture with UMC, has helped the company to aggressively develop the LED lighting market in mainland China.
Another technology development trend of Epistar is the introduction of the Embedded LED Chip (ELC), which uses a semiconductor manufacturing process to eliminate the packaging process, eliminating the need for leadframes and wire bonding. The chip is only compatible with phosphors. The encapsulant can be matched and can be directly attached. It is understood that the current ELC unpackaged chip products of Epistar have entered the market supply chain of backlights, and will be used in the lighting market in the future.
In fact, among Taiwan's LED manufacturers, including Taiwan Semiconductor Solid State Lighting Co., Ltd. and Yanyuan Optoelectronics Co., Ltd., have launched unpackaged chip products. Among them, the PFC package-free product developed by Yanyuan Optoelectronics uses the basic design of flip chip (FlipChip), which does not need to be wired. The advantage of the product is that the light efficiency can be increased to 200lm/W, and the illumination angle can be more than 300 degrees. In the ultra-wide-angle full-period design, the secondary optical lens can be eliminated, thus reducing the light efficiency and product cost.
TSMC's solid-state lighting, after the release of the unpackaged PoD technology (PhosphoronDie), recently introduced the TRx series of light panels using unpackaged LED module technology. The unpackaged PoD module is a flip-chip structure developed by TSMC Solid State Lighting. The advanced process is used to coat the phosphor with the chip, and it can become an LED light-emitting component without an additional packaging process. Tan Changlin, general manager of the company, said that such components have the advantages of small size, high lumen density, 150 degree illumination angle, elastic lumen combination, uniform color temperature, and high driving voltage.
