[Text / high-tech LED Gan Qin] 2015 market conditions are not as expected in the industry at the beginning of the year, although the market size still maintains growth, but the company's profitability is sluggish, the increase does not increase profits become a lot of companies can not hide. "Magic", which also includes LED packaging accessories companies. According to a survey by the Institute of Advanced Industrial Research LED Research (GGII), the sales volume of phosphors in 2015 is expected to reach 184 tons, a year-on-year increase of 34.8%. The increase in sales volume did not lead to an increase in sales. On the contrary, its sales volume declined compared with last year. The output value was about 695 million yuan, a year-on-year decrease of 12.63%. The same was true for packaged silica gel. In 2015, the sales volume of China's LED packaged silica gel market reached 1,500 tons, a year-on-year increase of 21.4%, and the output value was about 1.12 billion yuan, down 3.4% year-on-year. As an important auxiliary material for LED packaging, phosphors and glues occupy a significant proportion of the cost of packaging. In order to reduce the cost of LED industry chain, packaging companies use auxiliary materials as the main way to reduce costs. Packaging materials companies are facing shrinking profit margins and survival. It is getting harder. Can't escape the "price war" Recently, many LED accessories companies in the high-tech LED WeChat group spit water, whether it is phosphor or glue, the profits of the entire industry has been compressed to a very low level, from the previous high-profit era to the meager profit or even no profit era. From the action of this year's LED packaging manufacturers, most of the companies are expanding production in order to expand the market size. Although the overall performance is measured, the price of the device has dropped too fast, so the packaging factory requires the price of the auxiliary materials. The corresponding price reduction. Like most companies, Chen Yongsheng, general manager of Jieguo New Materials, said that the overall glue market situation is relatively sluggish this year. The sales volume has increased but the price drop has become more prominent. When talking about the overall market next year, Chen Yongsheng said that he is not very optimistic and will not appear. "hot" state. In fact, from the perspective of the glue industry, “localization†has become a trend. Foreign brands have begun to suffer huge impacts in the domestic glue market. The main reason is that domestic enterprises are trying to fight the price and actually let foreign companies “can’t stand itâ€. According to GGII research data, the average price of domestic LED low-profile silicone last year was 200-400 yuan/kg, and the price of high-definition LED silicone was 1000 yuan/kg. By this year, the average unit price of domestic LED low-profile silicone was reduced to 100-150 yuan/kg. The average unit price of high-fold silicone is reduced to 600-800 yuan / kg. Li Benjie, CEO of Lianlang New Materials, pointed out that because the price of the packaging factory is very strong this year, companies without quality advantages can only choose to fight price wars, which is why the price of glue continues to drop. The competition for low-tech products has often evolved into price competition in the end. The truth that is not circulated in the industry is not only suitable for glue, but also for phosphors. From the technical point of view of phosphors, the technology of YAG yellow phosphors for ordinary white LEDs has been improved rapidly, and the overall level of light efficiency has also been greatly improved, which can basically meet the demand for ordinary white LED products. However, this phenomenon also exacerbates the low The competition in the end market has caused the price of YAG yellow powder to rapidly drop to near the cost or even fall below the cost, causing the industry to fall into vicious competition. According to the data reported by GGII, the price of phosphors has dropped ridiculously this year. The price of yellow powder last year was 0.75 yuan/gram, which dropped to 0.5 yuan/gram this year. The price of red powder dropped from 43 yuan/gram last year to 25 yuan this year. / gram, the price of green powder dropped from 8 yuan / gram last year to 4.5 yuan / gram. In fact, starting this year, general lighting has placed higher demands on the efficacy, lifetime, and color rendering of LED light sources. This phenomenon has led to the high-efficiency aluminate yellow-green powder and nitrogen required for high-color white LEDs. Compound red powder has become the focus of market attention. In recent years, phosphor companies such as Rare Earth and Keheng have focused on developing products such as nitride red powder. Technological innovation finds a way out Undoubtedly, through continuous technological innovation and improved performance to enhance the competitiveness of products, in order to maintain market share, in fact, whether it is phosphor or glue, although performance has entered the bottleneck period, innovation is far from over. As an important auxiliary material for improving the light quality of LED products, phosphors have been coated with traditional yellow phosphors on blue GaN-based LED chips in the mainstream scheme of white LEDs. The emission spectrum of this scheme is mainly yellow-green light, and it is pointed out that it lacks red light. Ingredients, which lead to the inability to improve. In the field of phosphors, it has become a higher goal for phosphor companies to obtain full-color LED phosphors with balanced spectral components. Keheng, Rare Earth, Hilde and other companies have developed full-spectrum phosphors as their technology. Upgraded product. Feng Rongbiao, technical director of Keheng Co., pointed out that since ordinary phosphors emit green light under blue light excitation, the long-wave component is absent in the spectrum, and a single white light cannot be synthesized. Therefore, it is necessary to adopt a method of regulating the matrix cation component, nitriding technology, doping technology, etc. The introduction of a long-wave emission center can achieve full-spectrum emission. That is, the blue light intensity is suppressed, and the red spectrum is compensated to make the spectrum more continuous. However, as far as the current research and development progress is concerned, it is still difficult to achieve the full spectrum. Liu Ronghui, director of the Rare Earth Luminescence Division, said, “There is a lack of light in the spectrum from 180 to 190. Therefore, the company is developing this part of the LED spectrum. In order to make a full spectrum phosphor layout for the future." In addition, it can be seen from the glue part that domestic manufacturers are also striving to find a space for innovation in order to seek new profit growth points by tapping into market segments. Li Benjie revealed that the company and Osram are currently cooperating to develop high-definition products that are resistant to UV and gas corrosion. In addition, the rise of plant lighting will also bring new directions to silicone companies. “UV packaging has high requirements for the high temperature resistance and viscosity of the glue, while plant lighting requires high resistance to moisture and cold shock of the glue.†In the future when the market environment is becoming more and more complex and the industry is full of challenges, if innovation is not made, it will be eliminated by the market. Jieguo Xincai is planning to set a new market by launching an innovative product, Optocoupler Protection Silicone 5960. "Opto-Coupling Silicone 5960 is a high-purity silicone material that is suitable for the physical protection of most optoelectronic component chips and interconnected wires, preventing joint contamination, and improving the performance of the device and stabilizing the device." Chen Yongsheng said At present, most of the optocoupler rubber companies use Dow Corning's glue. Domestic glue companies rarely involve R&D in this area, so the opportunity is great. From this point of view, standing at the time when the LED industry is about to die and die, it is a foregone conclusion for companies that have no technological connotation to face the elimination. Only through technological innovation can they be in an invincible position and look forward to the infinite possibilities of the future.
