Currently commercially available LED chips , the basic material to ALGaInP ( AlGaInP ), InGaN ( indium gallium nitride ) -based. Where: red, Huangguang Jing sheet material is ALGaInP; blue, white , green chips are made of InGaN.

With the outbreak of the LED lighting market is approaching the point , industry competition , industry consolidation continues to deepen , the trend will be more prominent. Enterprises through mergers and acquisitions, integration of resources , combining the complementary strengths in order to enhance the overall strength of a competitive advantage in the market really broke out . Since September 2012 , the industry has undergone major consolidation mergers 6 onwards , amounting to 4.095 billion , involving the three places , mostly joined forces to complete the production , distribution, patents , human resources and market integration.

Integration Tide Coming

As early as 2006 to 2007 years , LED industry in Taiwan on the adoption of the merger , reorganization formed a complete industrial chain and several giant industrial pattern side by side . In recent years, the state actively support, the rapid development of mainland China LED market , industry competition , began to differentiate between the companies. Facing the market , especially in the lighting market expansion soon, through mergers and acquisitions, integration of resources , combining the complementary strengths in order to enhance the overall strength of a competitive advantage in the market really has become the consensus of the outbreak of many businesses .

In 2013 , the industry has entered a critical period of consolidation , collaboration model requires multilateral cooperation between enterprises vertical and horizontal chain . 2012 upstream capacity of structural overcapacity, increased competition , mergers and acquisitions to some extent, reduce duplication of investment , reduce vicious price competition, the two sides to enhance the overall ability to withstand risks . On the other hand , on the outbreak of the lighting market expectations, many companies choose to complete capacity through mergers and acquisitions , channel , patents , human resources and market integration.

"Matthew Effect " Accelerated

Recent speculation of cross-strait LED manufacturers exit the message , in addition to Taiwan Kellett , Chinese manufacturers pumping more money due to banks , including Hung Kee lighting, Shenzhen Shifang face closure. Everlight chairman Yeyin Fu bluntly , LED lighting plants and energy-saving bulb factory , like before , there vendor consolidation tide , now just the first wave, will go to when not sure , but it should allow the industry towards a more healthy development.

Yeyin Fu pointed out that before the launch of energy saving light bulbs , but also took place three times a vendor consolidation tide , then lasted about 10 to 20 years , only to energy-saving light bulb industry gradually toward health , and successfully replace incandescent bulbs, LED lighting is also now walking such a trend, and now this wave of closures have occurred in low technology and small- capitalization firms .

Expected , as the industry has entered the high-speed growth, brands and channels combined , the depth of the consolidation trend in the industry chain will be intensified in recent years , Matthew will soon appear.

The Advantages of Integration

Competition in the expanding market for regional and enhance core competitiveness, such as the acquisition of BDO Runda NVC , three optical acquisition of U.S. equity Luminus, Taiwan Formosa Epitaxy and so on. Through vertical integration integrate acquisitions , corporate get through the upper, middle and lower reaches of the whole industry chain , to achieve the overall layout . Followed by cross-border mergers and acquisitions, encourage enterprises to carry out cross-border mergers and acquisitions are an important driving force for patents and international markets , LED patent lies in the long-term international giants in the hands of a few large , especially chip links, through the acquisition of foreign companies can circumvent patent barriers , access to international manufacturers patents support.

Integration is power, and mergers and acquisitions is undoubtedly an effective way of resource integration in the economic globalization today has become quickly realized capital accumulation , possession of resources , an important way to market expansion , industry consolidation is behind all sorts of resources further to the advantage of corporate concentration, thus showing the survival of the fittest to survive . Only through the baptism of Ebb Tide , in order to make the entire industry more healthy and orderly development , integration is a necessary process industries , by industry professionals sentence : "LED lighting journey , turn over is an oasis . "

Industry Group Inflection Point Almost

Upstream chip market : in 2012 , the overall size of China's semiconductor lighting industry reached 192 billion yuan , an increase of 23 % compared to 2011 's 156 billion yuan , the growth rate has slowed down and become in recent years the domestic semiconductor lighting industry lowest rate of the year . Which the scale of the upstream epitaxial chip package midstream and downstream applications were 80 billion yuan, 32 billion yuan and 152 billion yuan . Among them, the 2012 domestic enterprises chip revenue growth of 23% , to 80 billion yuan; 2011 domestic GaN chip capacity utilization at about 50% , the annual output was only 115 billion , output growth was 63% , much larger than the value growth . Overall, the localization rate of 72% of the chips in lighting applications has also made ​​great progress , especially the competitiveness of small and medium -power lighting applications homemade chips gradually revealed , although lighting chip market share is still low , about about 25 %, but in 2011 17% compared to a big increase .

Midstream package : in 2012 , China's LED packaging industry reached 32 billion yuan , compared with 28.5 billion yuan in 2011 , up 12 % from 2011 production of 182 billion to 241 billion , an increase of 32%. From the product structure , SMD-LED package most obvious growth , accounting for about 50 % of the total production of LED devices , LED packaging has become a mainstream product . 2012 focused on small- size backlit Jufei and dedicated large-size backlight Ruifeng power dominate , 2013 is expected to continue .

Downstream applications : in 2012 , the overall size of China's semiconductor lighting applications reached 152 billion yuan , the overall growth rate of 24% , is the fastest growing part of the whole industry chain, but a more significant reduction in product prices influence growth has become in recent years a minimum. Lighting applications where output growth of 40% to 28% of the market share continues to be the largest market share of applications. LED lighting products yield more than 300 million , the rapid increase of domestic demand , exports decreased proportion , 56% ; backlighting applications increased 32 percent , accounting for 19 % of the total value of applications ; most mature landscape in 2012 growth has slowed , 19% , the proportion of the value of the entire application is 22% , compared to 2011 decreased ; LED display growth has slowed, the output value in the application of accounting to 13% . With the further decline in prices, has been the first to feel the downstream application vendors Spring plumbing .

LED Industry Ushered in A Watershed

Steady decline and enhance the quality of LED products prices, making the gradual recovery of demand , thus the industry , the downstream company collective benefit. Tongfang deputy Lianghai once in June for the Southern Reporter quite pleased to say that due to the abundant orders , machines are running at full capacity . That time, the number of LED CEOs of listed companies to disclose such phenomena are not uncommon .

Has become a trend to improve industry concentration

Secretary-General of Guangdong Provincial Association of Lighting Liu seems to LED for small companies, the government can not get the big one , the fierce competition in quality and price is no advantage, multi- channel construction on the threshold of reasons to enhance competitiveness as a result of the lack of face may not does not exit the grim situation.

Government orders , for example, the Government will set a general requirement , small businesses and government naturally large orders doubted see tears in their eyes . The fierce competition in the industry , some SMEs rely on low-quality , cheap win, but once a batch problem will be affected poor. " Zhongshan Hung Kee before we sell 10 dollars when he sold only three , a light meager profits , then pressing some suppliers of funds . " A LED industry sources . In terms of sales channels, due to the rapid growth of e-commerce channels , many agents and distributors rely on past traditions down to level grade distribution in a way no longer work as before . The electricity supplier for warehousing, logistics, Internet operators have certain requirements, it is difficult to keep up with the small and medium companies . In the long run , between the downstream enterprises to accelerate the merger integration is conducive to the entire LED industry matured further , let the market return and orderly competition .

China is experiencing an unprecedented rapid urbanization. According to Chinese Academy of Social Sciences in 2013 City Blue Book 2020, China 's urbanization rate expected to reach about 60%. The estimates show that by 2020 and 2030, the country needs to transfer the total agricultural population of people will reach 300 million and 390 million .

In fact, in the past 30 years , urbanization not only for black and white data , more expansion of city size , city life becomes more colorful , urban population continues to increase. Of course , there are many attendant negative effects , such as environmental pollution, traffic congestion, rising crime rates , and so on .

How to solve urbanization problems brought about changes in the process , become a subject of government, business , the public face together . In the twenty-first century, the largest urbanization process in China will be the world's emerging markets and Third World countries urbanization template. And China 's goal is to build a sustainable competitive with cities, it must contain livable , economic development, cultural tolerance and environmentally friendly , "urban " features such as convenient transportation and many other aspects .

Urbanization Opportunities

Urbanization will drive hundreds of millions of peasants into the cities , forming China 's emerging consumer groups. Gradually release their consumption potential , will become the new engine of China's economic growth. Rapid urbanization promote social progress and economic development, but also many challenges associated with the urban environment , infrastructure, management and other aspects ; and this one, the city's energy consumption is especially noteworthy.

Urbanization process, the innovative LED lighting technology apparently got the biggest development, but it has also become a time to solve the problems of urbanization , a particularly critical technology.

LED light-emitting diode , compared to traditional incandescent, halogen , fluorescent lamps, sodium lamps, high intensity discharge lamps and other lighting products , which is the best currently available energy-saving lighting products , power consumption of only ordinary incandescent ten one points. Currently, lighting accounts for about 20% of the world's total energy consumption energy consumption. As the world's energy consumption big country, China's energy consumption per year on lighting huge . According to professional statistics, if 50% of the Chinese lighting system replaced with LED, then the annual savings in electricity can build 2.5 Three Gorges Power Station .

In addition , LED as well as a prominent feature is a very long life , energy saving lamp life in general from 6000 to 8000 hours , while the life expectancy of LED lighting products under normal conditions up to tens of thousands of hours. LED long life make the use of cost , compared with the original urban lighting has a huge cost advantage.

Secretary-General of Shanghai Municipal Lighting Industry Association Wengyin Fu said in an interview , whether incandescent, fluorescent or LED lights , electricity costs account for over 60% of the overall cost of the LED lamps have very high luminous efficiency, low energy consumption , and therefore the long term point of view , the use of LED lighting integrated the lowest cost, as of 2012 , the overall cost is less than 25% of incandescent lamps (LED production scale continues to lead to lower costs in ) .

On the one hand because of the huge advantages of LED , but also benefited from the global pace of urbanization is accelerating , according to the forecast 2020 global LED lighting output value will reach $ 65.8 billion . According to reports China Taiwan Industrial Technology Research Institute Industrial Economics & Research Center , Greater China LED market reached $ 6.9 billion in 2012 , can be expected in 2015 , will reach $ 11.1 billion , a CAGR of over 20 %.

Create Livable Cities

Modern urban lighting is seeking a visual harmony , so that residents feel the harmony of light because it involves a series of questions the intensity of light , color , light the way , such as the principle of projection . LED lighting to meet this demand, its brightness and color temperature control, made ​​into lamps variety, which are so "light " content is greatly enriched .

Smart and energy efficient LED lighting solutions can not only enhance the residents a sense of security in the city streets , improve the quality of life of the people of the city , but also to enhance the personality and charm of a city , and promote the development of its business and tourism . Guangzhou landmark building , the world's highest TV Tower - Guangzhou TV Tower ( also known as the " waistline " ) , for example, during the Asian Games in Guangzhou in 2010 , the tower became a colorful Guangzhou Guangzhou skyline of the most beautiful scenery , but also to get the charm of Guangzhou Asian countries enjoy the show in front of the guests , and now she has become the tourists will go to Guangzhou tourist attractions and landmarks.

Guangzhou Tower bright colors and vivid results from more than 6,000 sets of LED lighting, almost nearly 330,000 LED pure particles can exhibit one million infinite changing colors. LED technology also allows the use of large-scale landscape lighting project that greatly reduces operating costs, a rough estimate, the power consumption of 500 kilowatts an hour , less than 1,000 yuan, more than twice as energy-efficient than traditional lighting solutions .

In addition to illuminate the outside , LED intelligent innovative applications also realized the intelligent control of lighting , traditional lighting and lighting unit for each two-way communication , making it impossible to monitor their fine work and can not according to the surrounding environment ( depending on the weather , flow and other changes ) to adjust the lighting to give , but the innovative use of LED lighting management allows the city to become more intelligent , such as traffic rarely midnight , road lighting brightness may rush hour would be quite different. LED intelligent control highlights the advantages of unparalleled innovation , technology and innovation demonstrates the tremendous power to change the living environment .

This will be a combination of LED and Internet innovation and technology , will make the vision of the first things to achieve in the lighting field , through light and dark or light color controls make lighting environment for people to work, study , and provide a better life healthier intelligence services. Meanwhile innovative intelligent lighting system also has a platform for the exchange of information and feedback , so that people in a relaxed environment while enjoying the lighting , lighting applications can communicate with each other on the platform control information.

LED intelligent application of innovative focus on expanding the whole society saving , saving, saving intelligent lighting concept . Lighting Research Institute of Fudan University , Professor Chen Dahua , said in an interview , intelligent , networked LED lighting will become the trend of the future , but for the city manager , this " intelligent" city management will bring light pole great convenience. Today, the rapid development of LED technology , not only to meet the needs of the lighting , but also help cities reduce energy consumption, reduce urban operating costs. On this basis , the intelligent lighting solutions will further , not only can automatically control lighting system , but also through the innovative application of interactive data , connectivity and other technologies will be the city's public lighting system access "Energy Internet" , thus achieve urban management information, intelligence , improve operational efficiency of the entire city management system.

The LED is a LED lighting Ⅲ - Ⅳ aromatic compounds, such as GaAs ( gallium arsenide ), GaP ( Gallium Phosphide ), GaAsP ( gallium phosphorus ), and other semiconductor. In the LED industry, in 2009 the consumption of the metal gallium is about 25 tons in 2010 to about 50 tons in 2011 will reach 75 tons , in 2012 exceeded 100 tons, together with the modern semiconductor industry ( wireless communications and LED lighting ) using amount accounts for about 80 percent of annual production of gallium metal . It is due to the development of downstream industries led LED demand for the metal gallium explosive growth .

According to global market research firm TrendForce LEDinside 's Green Energy Division estimates that in 2014 the output value of LED lighting market $ 35.3 billion , representing a growth of 47.8% in 2013 , 2014 LED lighting penetration rate will increase to 32.7%, TrendForce senior analyst Philip Kwok Ho said that in order to meet the 2014 new ball LED bulb and lamp market demand forecast still add 250 MOCVD machine capacity.

LED lighting applications surged , so strong demand for LED lighting , LEDinside estimated that LED lighting market in 2014 was $ 35.3 billion value , compared with 2013 growth of 47.8% in 2014 LED lighting penetration rate will increase to 32.7 %, with bulb and Lamp penetration rates of 20 % and 15 %.

On the 2014 LED lighting needs to move up the situation seems to competitive LED chip factory in 2014 still continued to increase production capacity , Guo Zhihao said that to meet the 2014 new ball LED bulb and lamp market demand is still forecast must add 250 MOCVD machine capacity.

This year the LED chip factory utilization rate , the LED chip production line in Taiwan and China are in the high plant capacity level , while Chinese market, although there is still not a small number of non- MOCVD machine , utilization , but these machines in a small multi- master costs in the hands of factory price competition in the market remains intense , the small plants to start these MOCVD machine is too high , is expected to exit the small plants will continue to supply LED market .

In addition to continuing to enhance the yield , running machine running times and the number of days outside the LED chip maker forecast 2014 merger may also take a small factory for a way to amplify MOCVD machine capacity , Guo Zhihao further said that it was amplified MOCVD machine Taiwanese point of view, under the LED chip factory shipper must wait MOCVD manufacturers , coupled machines, transfer machines also need to spend some time , in other words , the purchase of new machines can not provide immediate production capacity in a short time , therefore , LED chip giant mining merger possibilities ways to increase capacity of small plants greatly increased production capacity in order to be ready to fight on the occasion of the LED lighting market fast takeoff .

Referred to as a light emitting diode LED. The gallium (Ga) and arsenic (AS) diodes , phosphorus (P) compounds made ​​when the electron and hole recombination can radiate visible light , which can be used to make light-emitting diodes. LED is called the fourth generation light source , energy saving, environmental protection, safety , long life, low power consumption, low heat , high brightness , waterproof, micro, shockproof , easy dimming, beam focus , easy maintenance , etc. , can be widely used various directions, display , decoration , backlight, general lighting and other fields. Among them, indium gallium nitride (InGaN) - near ultraviolet , blue, green, and blue .

National Cheng Kung University in Taiwan has used indium gallium nitride growth process developed nearly green LED, which makes the device a peak external quantum efficiency reached 48.6% . The process involves the conversion of indium nitride and gallium nitride grown in 2 seconds burst (bursts) when .

Green LED light to enhance effective way many researchers are exploring . Currently, the production of highly efficient LED still not ideal material because yellow-green band (gap) is present in red-orange and indium gallium nitride arsenide / phosphide devices between blue visible spectrum .

This LED material growth in the Thomas Swan 19x2 -inch dense with spray head (CCS) MOCVD system patterned sapphire substrate. CCS technology is owned by AIXTRON . Diameter sapphire pattern is 3.5μm, the cone angle of the array gap of 2μm . Pyramid height of 1.3μm.

Organic metal nitride semiconductor epitaxial source trimethyl gallium , trimethyl indium and trimethyl aluminum (TMG, TMI, TMA) and ammonia ((NH3), nitrogen gas . InN / GaN transformation ( Figure 2 ) is the active light emitting region a multiple quantum well (MQW) executed. conversion loop comprising the TMG and TMI 40 seconds burst ring ammonia gas is maintained constant. researchers have grown in the wells of a standard production of TMG and TMI constant MQW (LED I).

The epitaxial material and X-ray analysis showed PL , InN after conversion / GaN growth wells (LED II) better crystal quality . LEDII PL FWHM of the (FWHM) of 24.6nm, LEDI of 29.1nm. also show x-ray , LED II is 89 arcsec, LED I is 93.5 arcsec. With wider peak (satellite peaks) with increasing surface roughness or alloy composition changes related.

When the injection current is less than 120mA, LED I forward voltage of 3.35V, while the LED II was 3.34V. In -15V when , LEDI reverse leakage current 53.7μA, LEDII to 5.1μA. Its current and voltage curves shows that by the ideal factor (ideality factor) measurements that , LEDII reduced non- radiative recombination , non-radiative recombination will reduce the luminous efficiency.

The researchers believe that a better ideal factor and reduce the reverse current leakage , due to LEDII transformed InN / GaN growth process in green InGaN / GaN MQW crystal quality improvements.

Electroluminescent (EL) light output and external quantum efficiency (EQE) data confirm the ideal reverse current leakage factor and the expected ( Figure 3 ) . When 120mA, LED I and II of the optical output power of 89.5mW and 110.2mW. Respective EQE were 30.8% and 37.9% . LED II peak EQE of 48.6%, LED I was 34.0 %.

Lack of LED II is when the light fades 350mA peak of 44.6% . LEDI , compared with 30.7%.

The researchers also studied the problem of blue shift and FWHM of EL spectra . The study showed , LEDII crystal quality improvement to enhance the polarity of the electric field stress mutagenesis (strain-induced polarization field), which also resulted in greater quantum confinement Stark effect (QCSE), QCSE electrons and holes are large electric field to separate , lower light. The researchers said , which leads to the emission wavelength of the blue LED II drift and bad light than LED I great.
