The LED market has opened a 100 billion mark, and a bloody hurricane LED breakout battle is inevitable. As an emerging sunrise industry, the LED industry not only has hundreds of billions of economic value, but also has enormous social value of energy conservation and environmental protection. The LED industry chain includes upstream equipment manufacturing, raw materials, chip manufacturing and packaging to the midstream, and downstream LED applications, namely chip manufacturing equipment, chip manufacturing, packaging and application industries. The bright and troublesome chip manufacturing equipment, MOCVD manufacturing, is the commanding height of the entire LED industry chain, and the technical barriers are extremely high. According to relevant data, in 2012, AIXTRON of Germany, VEECO of the United States and Dayang Nippon Acid of Japan achieved a market share of 90 MOCVD equipment manufacturing in the world, and few Chinese companies can compete with international first-tier companies in this field. The chip manufacturing field is an important part of the LED industry chain. From the perspective of industry concentration, according to LEDinside data, the concentration of LED chip industry in mainland China increased further in 2013. From the top 5 manufacturers' revenue market share, it increased from 61.9 in 2012 to 64.4, and is expected to reach 67.5 in 2014. The largest domestic LED chip manufacturer Sanan Optoelectronics data shows that in 2014, it will form an annual production capacity of 10 million LED epitaxial wafers and 300 billion chips, accounting for more than 58 domestic total production capacity, ranking first in the country. Asia is third and the world is tenth. Although Sanan Optoelectronics has become the leader in LED chip production at home and abroad, it is unable to open up overseas markets because the global high-end LED lighting chip market is dominated by five global companies (Nichia Chemical, Toyota Synthetic, Cree, Philips Lumileds and Osram). The five leading companies maintain their competitive edge and market share with a range of patented technologies that cover the entire LED value chain. Only a few LED chip companies with advantages in scale, brand, technology and channel resources can win and increase market share, while most other SMEs will be eliminated by fierce market competition in the next few years. Another important aspect of LEDs is packaging. With the continuous development and evolution of LED packaging technology, packaging technology has evolved from formal to vertical and flip-chip, and wafer-level packaging technology is now maturing. Flip-chip and wafer-level packaging technology is an extension of the chip to the package, that is, the chip manufacturer will directly complete the packaging process in the future. The market space for this package will be compressed. As a result, in recent years, LED packaging companies have either been actively transformed or faced with being acquired or bankrupt. For example, Guoxing Optoelectronics extends upstream and downstream, involved in upstream chip manufacturing and downstream LED lighting; Jufei Optoelectronics extends from backlight to backlight film; Wanrun Technology acquired Sunshine Optoelectronics, and its business extends to areas such as logos and lighting applications. Most LED packaging companies will be more difficult, and industry consolidation is a big trend in the next few years. The application market broke out in 2008-2013. Although the LED application segment continued to grow at a high level, the growth contribution mainly came from notebooks, desktops, TVs, tablets, etc. of medium and large-sized backlights, as well as related backlights for small and medium-sized mobile phones. With the promotion of smart phones, the mobile phone backlight market driven by the change of the tide is once again active. During this period, the total output value of backlights accounted for more than 70%, and the highest proportion of medium and large-size backlights reached 55, which became the main driving force for the growth of the LED industry. The LED lighting market will enter an outbreak in 2014. According to the LEDinside report, the penetration rate of LED lighting in the global market is rapidly increasing. In 2014, the output value of LED lighting will reach 17.8 billion US dollars. The total number of LED lighting products shipped will reach 1.32 billion, which is 68% higher than that in 2013. The economic value of LED lighting is increasing. Prominent. The cost of upstream chips and packaging links is declining. The minimum price difference between LED lamps and energy-saving lamps is less than 1 time; the types of LED products that meet household lighting are increasing rapidly; demand is entering a stage of high elastic growth, and demand is greatly increased in price sensitivity; Look, in 2014, the world entered the second wave of incandescent lamps forbidden peak period, LED lighting has a clear substitution effect. The decline in the price of LED products, the improvement of light efficiency year by year, the improvement of energy efficiency year by year, and the extension of life expectancy have promoted the rapid development of the LED lighting industry. Up to now, energy-saving lamps are the key products for traditional lighting to counter LED lighting. According to the calculations of the industry, a family of 10 4 watt LED lights and 10 15 watt energy-saving lamps for comparison (4 watt LED light is equivalent to 15 watt energy-saving lamps), using 10 LED lights The annual electricity cost can be saved by about 200 yuan. Chen Wenji, chief operating officer of Foshan Lighting LED Division, said: At the beginning of 2012, the price of LEDT8 tube (a type of lamp) was 180 yuan, and by the end of 2012 it had dropped to 40 yuan. In 2013, the product of this model was reduced from 40 yuan to 20 yuan. Yuan; 2014 has dropped from 20 yuan to more than 10 yuan. The luminous efficiency is higher than that of energy-saving lamps, the price is lower than that of energy-saving lamps, and the lifespan is longer than that of energy-saving lamps. LED lighting products have broken through the line of protection of energy-saving lamps. The other major product of traditional lighting, incandescent lamps, has already entered the phase of elimination. As the fourth generation of lighting source, LED has replaced the traditional lighting has become the trend. The LED lighting market has developed rapidly. Now it has become a market with a space of 100 billion yuan, but the market concentration is still very low. For example, Sun Lighting is optimistic that the market share of LED lighting in 2014 is between 1-2, which is quite large. Room for improvement.
Stereo Light Curing Molding - Sla
STEREO LIGHT CURING MOLDING - SLA
It mainly uses photosensitive resin as a raw material, and utilizes the characteristic that liquid photosensitive resin will cure quickly under ultraviolet laser beam irradiation. The photosensitive resin is generally liquid, and it immediately initiates a polymerization reaction and completes curing when irradiated with a certain wavelength of ultraviolet light (250 nm to 400 nm). SLA focuses on the surface of the light-curing material by focusing ultraviolet light of a specific wavelength and intensity to solidify it sequentially from point to line and from line to surface, thereby completing the drawing of a layered cross-section.
