The First: lighting industry is in urgent need originality to enhance self-worth

How does the China led lights manufacturing advance toward the world? With what to enlighten the world? How does the Chinese brand create value?

In 2007, “made in China” has drawn attention–nearly 50% of the world’s clothing, 70% of the toothbrush, 75% of the toys, 80% of the microwave oven are close to the Chinese-made label. Unwittingly, Chinese manufacturing has gradually went into the daily lives of millions of households around the world.

lighting industry is in urgent need originality to enhance self-worth

Unlike toys, clothing and home appliance industry is so impressive, but the data show that China has become the world’s largest producer and exporter of lighting appliances country, in 2007, about 160 billion yuan output value of China’s lighting industry, exports of  $10 billion, accounted for 18% of the global market share. The lighting industry is quietly becoming the backbone of China’s manufacturing.

But on the other hand, the Chinese lighting industry is bright industrial , dark original imitation rampant, serious deficiencies in the spirit of the original. Someone will summarize all the chaos of the lighting industry for dozens of strange; It is not allowed to take pictures by the Western name famous lights sold as lights, sell lights as good as OEM.

The original deletion syndrome parsing

The underlying causes of the lighting industry in China, from my point of view, why they do not attach importance to the original value? it mainly for the following reasons:

First,  patent awareness weak. The Zhongshan Guzhen known Chinese lights are lighting manufacturing companies, thousand of brands, mid-held lights Fair fame, but really have patented technology, with the original products companies described as rare, the so-called new exhibition is nothing more than “wearing a new vest” old type, the so-called high-end manufacturing, which is nothing more than a face-lift mimicry. Truly international brand enterprises and international buyers are reluctant to dare not to participate in the Light Fair, because they are very clear: If they launch new products, one week or one month after their “twin brother”will appear in the Chinese market with low prices. The local enterprises known as  “coyotes” no patent consciousness, and do not respect the rules of the game.

Whether led street lamps are energy-efficient or not in this stage energy(the following)?

LED lighting is a “directive doctrine”. The reason is that the led street lamps have highly been light directive. The light emitted to the front which is fully utilized. For me, we have no objection to this doctrine, and do not agree with this point of view. I hope we still look at this issue from a pragmatic attitude. Perimeter and behind the light in the design of the product which needs to be reflected to the front of the reasonable use. To achieve the desired condensing effect of the traditional lamps, it has been such application. LED lights can not afford the higher junction temperature, and requires sufficient cross-sectional area of heat conduction, or else completely segment connected to the light-emitting LED package 360 degrees out.

The led street lamps directional actual encapsulated stand optical structure.  “directive doctrine” at this stage explain the doctrine of LED energy-saving straw. From the historical perspective of the development of long precedent.

The mainland has several packaging companies are good in the scale of production capacity and technology. If they can cooperate with each other, or system vendor support, there will be greater opportunities for development. From global view, the importance of the packaging stage is as important as the chip. There is still much room for improvement of high-power packaging technology, and improve more quickly. Therefore, the state should increase support for efforts to enhance the competitiveness of enterprises in this process stage as soon as possible, and enhance the market share of China’s mainland enterprises. So, it is expected that the competitive packaging factory will show up within a year or two.

In addition, There are just few small and medium-sized Taiwan’s electronics companies, such as Foxconn, 20 years ago, the turnover of their company is just 200 million CNY. That’s why they have to focus one the main chain industry. We have to invest so much resources to this industry at the the beginning of the development. There are just a few company can make it. The scale of Taiwan’s LED is just NTD 100 billion.It’s impossible for an enterprise to make put so much resource in this industry. Epistar choose the development model of the level of mergers and acquisitions at an early date.It’s difficult for Epistar to make the industrial chain integration finished. From pragmatic point of view, the stage of led street lamps are just in the horizontal level.

For the design products, it is the most basic products according with national standards, but we need time to prove.

LED industry’s future integration and the art(the following)

LED light industrial has been the focus in people’s life with rapid growth.
In this case, industry consolidation has become one of the hottest topics of the current phase of the LED industry.

Generally speaking, the way of industry consolidation can be roughly divided into vertical integration (mergers and acquisitions, equity participation or policy Union to create vertical industry chain from upstream to downstream) and horizontal integration (ie integration in the enterprise of the industrial chain of the same level) in two ways. At the current stage of development of LED industry, vertical integration seems to be more international. Epistar Corporation (hereinafter referred to as “Epistar) adhere to the level of integration of the main development. We can get a lot of experience. Epistar Chairman had a interview with magazine and Li Bingjie told us that he will explore the integration of art in the LED lights chip industry in the future.

LED industry's future integration and the art

The path of the horizontal integration of OEM

Semiconductor lighting: Recently, Epistar consolidation have sprare no efforts to make great progress in the industry. Jingke have become the important news in the LED industry. The Epistar have made some successful acquisition with M & A cases the element arsenic, Quan, Lian Yong, and a number of epitaxial silicon plant. But this also can be seen a phenomenon, that is, strategy is concentrated in the horizontal level, mergers and acquisitions of enterprises are the main epitaxial silicon plant. Why the Epistar take such an integration strategy?

Li Bingjie: As you said, all these years , the strategy focused largely on the level of integration. M & A is not the direction of vertical integration, although some vertical mergers and acquisitions is a shortcut to the future to enter the manufacturing system. The reason to do it is that it worked closely related to Taiwan’s development environment. Taiwan’s LED industry is rooted in a manufacturing environment of Taiwan’s electronic industry.It is the same as the characteristics of its development and other IT industry in Taiwan, emphasising on how to reduce the costs effectively. The point to reduce the cost for enterprise is to accomplish industrial chain segments.

Whether LED street light is energy-efficient or not in this stage energy?

When we talk about a problem, we will stand on our own position. Our own position always to win the upper hand, this is common sense. Many LED lighting aspects of the debate, you can describe the participants “hot”. I think we all know who can win the debate! The simple reason is that the future led street lights price is no suspense. Only a matter of time. Time hinder process is nothing more than from two aspects, namely, optical efficiency, the second is cost-effective.

led street lights price

When we are watching movies, we encounter the struggle between justice and evil. We will understand in the end, you just enjoy the process. Just the best of the  “LED lighting debates” metaphor. I think the actual point, instead of tax payer’s money to pay for the LED lighting engineering. National investment in LED basic and applied research should be more conductive to the development of the entire LED lights industry fishes.

 

The LED industry has developed rapidly, and the upstream chip has received more attention. The state has invested a lot of money to support more than a dozen from the chip factory. However, the chip plant has been gradually move toward integration, the bigger the stage, but Chinese investment is in decentralization.

Semiconductor lighting: In recent years, Epistar accelerate the industrial l operations on the mainland, for example, investment projects in Changzhou, Jingke. How about the ideas in Epistar LED industry cooperation?

Li Bingjie: Epistar Project in Changzhou includes epitaxy and chip two-stage of production, which can serve for the mainland system vendors, and to provide services for Epistar products. In the cross-strait industrial cooperation, Epistar enterprises may wish to do some virtual industry consolidation to work together, that is, industries complement each other. At present, several large television brand factory in mainland China, have both brand and manufacturing strengths and channel advantages. If they can cooperation with companies in Taiwan in the combination of components on the technical advantages and manufacturing advantages, so they can create more opportunities for development. Specific ways, each company may have different choices. The Epistar with mainland Chinese television factory has been some cooperation projects, which is expected to have concrete results within 2012.

Cultural integration and technology integration in the led industry consolidation

Semiconductor lighting: industry consolidation is a deep learning, which requires great skills, can you tell us about Epistar successful experience in this area?

Li Bingjie: One of the keys of company consolidation is to make their own corporate culture gradually to be accepted the acquired company. Of course, each cultural integration is not easy mentally, because of the acquiring party barriers, fear of being treated as second-class citizens. The most important of integration is that to be fair and consistent treatment to all employees and to give everyone the same opportunity. So that each employees can feel himself as the one part of this company.

LED industry

In addition, the integration of technology is also very important for an enterprise, which means that some people should give up everything familiar in the past, to learn and adapt to the new production environment. The Epistar generally took two approaches: First, the integration from new products, old products to maintain the original state. This approach has the advantage of avoiding the difficulty of technology transition during integration, but it takes a long time to complete. LED technology had the rapid changes and development in the past. When technological changes slow down, this integration process will be even longer. Another method is not to integrate, but going into a different market after technical analysis. For example, the Epistar M & Canton Ga, technically on the adoption of this integrated approach. Relatively fast rate of growth of wide gallium epitaxial structure has its advantages in cost. The two technologies take much more time if they want to support each other because of the epitaxial structure, but they may be affected by the original advantages.

The integration strategy of the mainland industry

Semiconductor lighting: more and more stated-owned enterprises are optimistic about the development of LED industry, ready to enter, even to enter the industry. What recommendation do you have for the development of LED industry?

Li Bingjie: 2012 to 2014 is critical time for the future development of LED industry in China. LED lights companies take about 1 to 2-year cycle from the construction of capacity to stabilize out. It is necessary to speed up the pace. We should make earlier decisions no matter to state new policy from the government or, or inputs form enterprises.

The major problems of the existing street lighting design

First of all, the most important issue is that the street lighting design is unreasonable. the bright places such as pedestrian trails carriageway, there is no light, rather than light ground Fang Ru fang grass, the back of the bench which Lovers meet, the light are bright. Light pollution, waste is very serious. It is non-compliance with the spirit of the “energy saving”. The reason is the pervasiveness of the landscape street lighting design expertise lags far behind the pace of development of the Chinese landscape lighting project, as long as you look at the Chinese city CBB area “room thing” how hot it is. Last month, we crash in Jiangsu, Anhui, Zhejiang during the investigation of a large-scale LED street lamp market suddenly discovered not only a slow lane on the road more than two street lights installed, evidently street lights have been put something more than a year or two of you, you think the lights are used to according to grass drops. Perhaps leadership are waiting for repair slow lane silver place it, the road is still not repaired, can the works of the street light settle it? LED street lamps can not just loaded regardless of credit growth! Some people even say: medium and small enterprises want big profit as long as the good-looking statements for the big enterprises.

street lighting design

Height of horizontal division of labour advantages, you can do a pretty focused, doing extended chip only extension chip, package package only, very centralized resources, a single process can be very precise, very competitive.Taiwan LED companies are doing a high degree of horizontal division of labour, so can do fine at all stages.But the upper LED is characterized by technology-intensive, capital-intensive, but not high profit margins.In the upstream industry chain, focusing on enterprise level consolidation, will lose because of vertical integration and created new opportunities for downstream.

The implementation of energy conservation and emission reduction does not make a fuss, just above the LED street lamp and science of lighting design are more potential. So regardless of the boss, street lighting design should base on the sustainable development of “people-oriented”.

 

LED industry’s future integration and the art

The most important reason for this is that adhere to the horizontal integration, focus on LED lights chip production, wafer photoelectric and customer has no competition and conflicts of interest, customers can be rest assured of cooperation with us.As long as a simple look will find, now both the packaging plant in the Mainland and the Taiwan almost all of the packaging plant has begun to industry chain downstream module, do the lights.In other words, as long as these enterprises along with chip stage get through industrial chain.It also means that as long as the wafer photoelectric to downstream step easily compete with customer situation.Wafer photoelectric simply horizontal consolidation is what you want to do a simple chip supplier.It can be said that the choice of timing-related, are also relevant to the concept.

LED industry

The semiconductor lighting: International Semiconductor lighting business, however this practice with several manufacturers are different.

Li Bingjie: Yes.Nichia currently has been doing outreach, chip, package, but also the small number of modules, such as Philips, OSRAM, Cree, do it all the time from the group level terminals the whole lamp dimensions, all focused on vertical integration.

However, regardless of the level of integration is vertical integration, which it’s hard to say who is good bad.Benefit of vertical integration is possible into the Terminal market, have the opportunity to close the client, it is possible to build a brand and channel.Establish a Terminal brand, you may enjoy higher profit margins.Of course, build brands and channels are very difficult things.Vertical integration is possible and must be of such ambitions, otherwise can only be limited to manufacturing.

The semiconductor lighting: wafer photoelectric do the action continued in the level of integration in the future directions, TSMC is likely to be LED industry (the world’s largest semiconductor foundry)?

Li Bingjie: actually, International has LED tube the industry in the LED industry was nicknamed wafer photoelectric company.As a matter of fact, OEM has wafer photoelectric current capacity of 30% per cent.If you prefer, this ratio could rise.From the horizontal integration mode of development is also a path in toward the body shopping.

LED lighting has the obvious advantages and promising future

For the low luminous efficiency, LED’s application is mainly in a variety of display areas. With the appearance of high brightness LED (especially white LED), many cities actively begin to use LED light source. Firstly, the government stressed to use the LED lights at the street, so that people can understand and use the LED light source. International authoritative institutions predict that we will enter into a new era of LED lighting industry represented by LED, which is known as the fourth generation light source.

LED lighting has the obvious advantages and promising future

 

The “green light” is a new concept, which is brought forward in the late 1980s in the field of foreign lighting field. The implementation of China’s “Green Lighting Project” began in 1996. An important step to achieve this plan is to develop and promote the efficient, energy-saving lighting appliances, saving electricity, reducing the environmental and light pollution, the establishment of a qualified and efficient, economic and comfortable, safe and reliable, environmentally friendly lighting systems. However, it is far to reach the requirements of “Green Light”, the development and application of more efficient, reliable, safe, durable, new light is imperative. Currently, lighting consumes takes about 20% of the entire power consumption, soled lighting industry energy savings for the industry is the important way to achieve energy saving. To reach this goal, we’ve researched and developed of many types of energy-efficient lighting apparatus, and achieved some success. Many countries have laws and regulations of the formal constraints to prohibit the production and sale of incandescent, China has also introduced the corresponding laws and regulations to constrain the use of the low light of the high-energy efficient lighting apparatus, and actively promote the use of low-power high luminous efficiency light source.

The United States, Japan and other countries and China Taiwan region predicted for led lighting industry efficiency, and 55% incandescent and 55% of the fluorescent were replaced by LED and saved $ 35 billion per year of electricity, and less 755 million tons carbon dioxide emissions each year. In Japan, 100% incandescent was changed to LED, which equals to two nuclear power plant capacity, with annual savings of more than one billion liters of crude oil consumption. In Taiwan, 25% incandescent and 100% of the fluorescent were changed to white LED, saving 11 billion kWh of electricity annually. Energy conservation is the main reason we consider the use of LED light source, perhaps the LED light source is more expensive than traditional light sources, but recovered with a year of energy-saving light source of investment in factories and business electricity, the use of energy saving of six to eight months to recover the light source investment to obtain the energy-saving net gain of four to nine times each year. Office modernization, the number of computers are increasing in China, with China’s domestic LCD TV, switch to the LED light source as a back-light of the LCD screen, its power is greatly saved. With the improvement of LED production process, SMD LED production process can replace LCD screen light LED products.

Lyon Festival of Lights make the world so green lighting led

About 500 km south of Paris, the city of Lyon is a long history of the city. As early as Roman times, it is a old town in France. Today, walking in the town, we can also see a lot of Roman occupation of the former period. The passage of time, the charm of the city of Lyon is diminished, especially as an economic center of the modern French, more glow with youthful vigor. On every year’s  Lyon Festival of Lights December 8th, guests from Lyon increased the color of the an international city, and become a large image of the signs of modern Lyon. According to reports, during the recent years, the Festival of Light, about 4 million tourists from France and around the world. Not only as the Lyon brought a lot of tourism revenue, but also to improve the world awareness of Lyon.

Lyon Festival of Lights has a half-century history. December 8, 1852, the whole community celebrate the the Havre Janvier mountains Virgin Mary image of gold completed in the evening held a grand ceremony. Every household in the window and point row of candle lights, hand-held lights to line up the mountain to celebrate the completion of the statue of Virgin Mary. Since then, the Festival of Lights on December 8 will settle down roots here, and will be a section of the city Lyon from generation to generation so far.

A major feature of modern Lyon Festival of Lights, light scenery effects markedly effective, the more you use the more energy-efficient green lighting led technology continues to improve, the Festival of Lights during the power consumption is declining, and the Lantern Festival is firmly marked by sustainable development of the mark. According to reports, due to the continuous improvement of energy-saving technology, and now continued four nights of the Festival of Lights, the total power consumption cost only  € 3,000, indicating that the Lyon urban energy-saving lighting technology developed. Lyon, city lighting costs are declining, because of the Lantern Festival, led lights by an average of only 11 euros a year.

20 years, the influence of the Lyon Festival of Lights continues to expand, Lyon, energy-efficient green lighting led technology innovation. Lantern Festival not only dress the city to drive economic development in Lyon, also in a certain sense, has played an exemplary role for city lighting worldwide.

Introduction of Photonic Crystal Blue-ray LED

White-ray LEDs are actually made by blue LEDs: as the name implies, blue LED will generate blue rays. After YAG phosphor powder, these blue rays will transform into yellow rays. And the combination of blue rays and yellow rays (in a certain proportion) will create white rays. White-ray LED lights are widely used in various white lighting and backlighting applications. This type of white light was also defined as solid white lighting, having three major features: small size, energy saving, long service life. But compare with traditional fluorescent tubes, these lamps have a much lower lighting efficiency. Photonic crystals are an effective solution for this problem.

 

White-ray LEDs are actually made by blue LEDs: as the name implies, blue LED will generate blue rays.

 

In order to solve the low lighting efficiency of Blue-ray LEDs, scientists infused photonic crystals into Blue-ray LEDs to create a new compound: Photonic Crystal Blue-ray LED. Traditional manufacturing process of LED is rather simple. But the point is their low lighting efficiency. Because of the total reflection of the surface of traditional Blue-ray LEDs, rays came out from active layers will be totally reflected by the reflecting surface.

 

Aiming at this problem, CREE made some enhancements in the production process. A tiny slope beside the active layer can be seen in each deformed chip. Light efficiency can be dramatically improved by adding these slopes. Another improvement is designing a secondary set of product surface. Through this structure, scientists also can increase the light efficiency. Planar is a complicated and precise technique created to control this structure. Light pass through the secondary active layer, this structure can improve the light efficiency to 80%. However, it is in the case of reducing internal quantum efficiency. In order to address this problem, scientists installed Resonant Cavity on photonic crystal LEDs. This design was named as Resonant Cavity LED. Among these LEDs, scientists configured photonic crystals. This method can increase the light efficiency to around 60%.

 

Because of the diffraction, Photonic Crystal Blue-ray LED can revise the light angle. Some technical processes should be taken to convince that the revised light angle be smaller than the critical angle of used media. Restricted by the critical angle, normally only 4% light can be emitted. Relatively Photonic Crystal Blue-ray LED with active layer has a much wider emitting angle, having wider area to send out rays, can consequently have higher light efficiency.
