China want to make the brand of led lights from china

LED (light emitting diode) have grown up rapidly in these years comparing to incandescent, fluorescent, particularly for the lights efficiency.Due to the technological advances and for low price, led also have been greatly used in landscape lighting and road lighting. With the deepening of the concept of the global energy saving LED energy saving and environmental protection, LED plays an increasingly important role.

led lights from china

LED enjoys a very long industry chain, from upstream of the substrate material, epitaxy, chip to the device package and the application, which covers the semiconductor industry and the lighting industry. LED lights from china have been widely used in various integration industry, so it entered into the pilot and demonstration phase of the indoor and outdoor lighting.

According to our statistics, he overall development of the industry in 2008 is lower than expected at the beginning of the year, it is clear this is due to the impact of the international financial crisis in 2008. In 2009, the industry’s development situation improved rapidly, corporate investment and capacity expansion is accelerating. The technical level are still gaps. Midstream device package, product structure has been significantly improved, especially the functional lighting technology breakthrough, but generally small scale enterprises, have not yet entered the large-size back-light, automotive lighting applications. Downstream applications can be said to be flourishing landscape, display, functional lighting applications.The world’s leading technical level has improved significantly, but has not yet formed an international brand.

LED lights from china has been the focus in the development of Industrial layout It can be said that the development pattern has begun to change. Domestic cities actively to announce the construction of semiconductor lighting industrial. This industry will form a new pattern within 3-5 years for 4 central region of the pattern is broken

It will accelerate the LED industry from the aspect of investment. Private capital have been actively involved in the investment of LED industry. LED lights from china also get huge investment in various industry. In recent years, more than 1.5 billion yuan are invested in domestic enterprises. In the first half of 2009, all over the country have launched the LED project, a total investment budget over 20 billion yuan. The huge orders shows the attention and promotion of the capital for the LED industry.

With the rapid development of the industry who will become the GE, PHLIPS international industrial giant, worth the wait.

LED lighting market competition’s success or failure depends on the efforts in the past two or three years

In Japan, with large electrical manufacturers attending the LED lights market, LED lighting shows a trend of universal access. In this area, as the old lighting equipment manufacturers Toshiba ambitious, and strive to sales of 350 billion yen in 2015. Recently, the reporter interviewed Toshiba Lighting business prospects of the company on behalf of the Executive Vice President to attend the “Green Device 2009” Mariachi Malachi.

If you want to win in the led lighting market business, what we needs to be strategic? In semiconductors (Toshiba ranked third in the world), the master key is the leading, and the scale of investment in terms of miniaturization technology.

LED lighting is a far cry from the nature and semiconductor business. Differentiation through technology is important, but also the exploitation and marketing a large amount. Accordingly, the Company has not been involved in the field looking for the right partner. In particular, we paid special attention to explore the European and Chinese markets, and we has long been studying strategic access to these markets. The existing lighting equipment, which had already established a wide range of sales channels, also be our advantage in the led lighting market business.

With the possibility to produce a effect between the semiconductor business is not too much?

This situation does not exist. LED lighting business can take full use of the experience gained through the semiconductor. In the field of LED lighting, we will focus on the module instead of the chip, but in technically, a lot of part keeps the same with semiconductor process (encapsulation). Although a slow start in the LED chip,  yet the future will keep positive efforts and included in the scope of business.

Including overseas manufacturers to get involved, led lighting market will become a very competitive field.
South Korean companies has been positive, the competition will be very cruel, and we have to be mentally prepared. Business efforts in the past two or three years will determine victory or defeat in the business. LED lighting has long life, that is why, once the market competitors occupation, it is difficult to have the opportunity to turn around. In this field, we will endeavor to establish the status of the first suppliers. To this end, in 2015 to invest 100 billion yen in operating resources. Compared with the semiconductor business investment in equipment, this amount is just a very small scale.

3. High reliability and intelligent creative are two main lines of the future design of LED products.
LED application market is a high degree of refinement, a wide range of future product trends, and also ever-changing, but the original aim never change. LED technology characteristics determine the future direction of the LED products.

Whether compared with the traditional lighting technologies or the further  laser lighting and display technology, domestic LED lighting, the most fundamental features,  is its high reliability and intelligent control.

domestic LED lighting

Due to technical immaturity, a few years ago, a number of LED application products appear in the practical application of a lot of reliability issues, such as short life, the light fades serious job insecurity, which in a certain extent, affected the LED products overall reputation. High reliability is not just a life to reach a certain standard, it includes the consistency and stability of the product. Reliability requirements, special lighting, general lighting, LED chips with high reliability, high stability advantages in packaging or assembly areas have been greatly reduced. Here, thermal management is a basic and important issue.

The biggest advantage of LED technology is that it can achieve intelligent control. As semiconductor devices, LED can  intelligently adjust the light intensity, change the spectrum, and even change the lighting pattern. These advantages can not be realized by the traditional lighting. That LED’s intelligent control let LED easily integrate with other technologies and formulate of new creative products. For example, one of the U.S. government project is heavily subsidized to use the LED light for indoor or short-range communication. Another example, domestic LED lighting products and solar, infrared sensors, microwave measurement devices were assembled together, they can achieve a series of unexpected and unique application.

Intelligent control of LED-based creative products for the future of home lighting market is the key to success of the competition. LED lights can not only be seen as a substitute for traditional energy-saving lamps. LED brings not only a new round of revolution, but also a new light culture.

Whether industrial lighting, commercial lighting, home lighting, or display or backlight, intelligent creativity is extremely important concept. That is also the key for LED application products market

1. LED industry follow the laws of the market for the semiconductor industry.

As we all know, LED has the advantages of long life, intelligence and other traditional lighting alternatives because its high luminous efficiency(energy saving). Therefore, a considerable number of LED manufacturers are naturally emulate the operation of the operating model of the domestic LED lighting. However, this is fundamentally wrong with that. LED is a semiconductor technology. LED industry should follow the mode of operation of the semiconductor industry and market discipline.

domestic LED lighting

In the LED application products, both from the point of view the performance determinants or cost factors, internal tiny LED lights chips account for more than 60%  of the entire product. Upstream chip processing class IC technology by the semiconductor industry, with the characteristics of high automation, high consistency, high integration, high research and development costs, low processing cost, low processing costs. This feature is significantly different with traditional lighting.

LED industry has a significant middle part-packaging components, package links basically using standard semiconductor packaging processes, such as SMT, welding. Midstream package standardization which is essential for downstream application diversification.

In detail, unlike traditional lighting, domestic LED lighting belongs to the filed of semiconductors, technology-intensive, the design and processing of separable, the middle and upper reaches of the industrial chain standardization and other characteristics. So, in the semiconductor industry, the prevalence of large-scale production and the production process is relatively standardized chip and package-generation plant, design company can be out of phase with the dominant production foundries, higher costs of product design, technology updates soon, and the product the generation of processing costs are relatively low.

For the domestic LED lighting application manufacturers, the midstream LED package standardization of components makes key is how competitive differentiation, personalized to design, how to do, “I have no people, there I am.” So, according to the company’s own resources, how to find accurate market segments, and how to tap the potential market opportunities, how solid the existing market share and how creative open new markets for mission-critical market sector. This requires that the market must have extensive technical background, because the design of the applications involves a considerable number of technical areas, such as mechanical, thermal management, electronic control, semiconductor, optical performance, and even extends to advertising creative, light and shadow, Psychology and other fields.

The main exit of the domestic LED lighting enterprises in the next three years(one)

Currently, the domestic LED lighting manufacturers are at a critical period. In one hand, with a global energy crisis, environmental degradation is increasing, governments as a further-generation light source technology has given great support, and coupled with the rapid development of LED technology and LED manufactures efforts, so far, that LED lighting to replace traditional CFFL, has become the consensus of the trend of energy-saving lamps. This means that, LED manufacturers are facing a very huge market. However, on the other hand, many of the domestic LED lighting industry testing standards are not established, the entire market is highly competitive and disorder. Even, the abroad LED giants, such as Cree, Philips, Os-ram, etc, are aimed at the Chinese LED lights market and actively market layout. There are indications that in the next 3-5 years, LED lighting truly replace the traditional lighting of the era is coming, then the market conditions of the LED into the tens of trousands of households will be basically sound, such as macroeconomic policy, industry testing standards, business models, the degree of maturity of the industry chain, performance indicators, and the scale of production, and so on. At that time, LED industry will experience a massive shakeout in the market restructuring exercise.

Therefore, for the domestic LED lighting manufacturers, currently the most important issue that should be considered is that after 3-5 years, when the LED industry face the reshuffle, how to survive in the fierce competition of the domestic manufacturers and  foreign giants suppress crowding both internal and external pressure? If survive, what role to continue fighting in the market? Be a brand designer? Or OEM factory? Or something else?

For the popular market in the industry point of view, we do not dwell on them. Here is a little of my personal thoughts, Hope we all look on.

First, LED industry characteristics

Judging from the perspective of industry chain, LED industry can be divided into upstream LED epitaxial wafers and chips, the middle reaches of the package components downstream applications such as the three links. From the application of LED lighting, display, back light, three sub-markets. And the point of view from the field of product applications, LED application is divided into industrial areas, commercial areas and civilian fields.

 

How does LED lighting industry become bigger and stronger (three)

Third, how to achieve breakthrough LED lighting industry in China in the core high-end chip?

Breakthroughs in core bottlenecks, time and tide wait for no man.

In fact, the Government in the LED chip R & D has also given strong support, but it has no much effect. The reason: one is that we do not really aware of the high-end chip core and a key position in the LED industry, the overall funding efforts go far enough; second is that funding is too scattered, chip R & D is a capital-intensive projects, That too little input will be no substantive progress; Third, the entire LED lights industry, universities and research institutes, failed to unite, failed to achieve the centralization of R & D resources sharing mechanism.

How does LED lighting industry become bigger and stronger 3

Personally, I think the core high-end chip breakthrough LED lighting industry in China from now on, you must pay attention to the following aspects:

1. attaches great importance to concentrate funding.

There is no denying that the government has attached great importance to the LED industry. However, for the core-high-end chip R & D for the LED industry, they pay little attention in the true sense. While the government is trying to major projects, targeted to support chip R & D, but now, in the face of the facts of a larger technology gap with foreign chip makers, the distributed funding has been difficult to work.

Foreign chip makers in the initial phase, funded by the national government in the protection of the innovation system, and soon to the rapid development and has a certain influence. In China, due to the innovation system is not perfect, it could have been in the initial phase to less funding support to the rapid growth of the hatch mechanism can not function effectively,  resulting to the present, the state must pay more money to help the industry. This is a hard lesson for us.

Thus, we must be aware of the extreme importance of the upstream chip LED lighting industry, followed accordance with previous practice, we can not diversity funding as previous did, if doing so, it does not effect for the chip R & D.

How does LED lighting industry become bigger and stronger (two)

Second, why the high-end chip is the core of China’s LED lighting industry?

1, today’s high-tech industry development law.

LED industry is semiconductor-related high-tech industries. Throughout today’s high-tech industries, especially semiconductor-related high-tech industries, such as integrated circuits, communications, laser, and the upper reaches of the chip is often the key to the whole industry. This key role is not only reflected in the performance and price of the upstream chip determines the  performance of the middle and lower reaches of the product and the price is also reflected in the chip suppliers tend to control the patents and standards of the industry as a whole.

How does LED lighting industry become bigger and stronger 2

Although LED packing stage cooling problems and the optical design of the application stage have a certain impact on the performance of the final products,   Yet it must be admitted, LED lighting industry chip performance decide the entire products. For example, if the chip light efficiency can not reach 100lm / W, the stability and realiability of the chip itself is bad, even no matter how good the heat is, and how excellent optical design is, it is difficult to achieve the requirement.

More importantly, the chip-level competition is for the LED industry in China, competitive differentiation, and packaging and application-level competition more biased homogeneous competition. That is to say, compared with foreign manufacturers, China’s high-end LED lights chips is gaps, both qualitative difference exists, therefore, foreign chip makers, it is easy to obtain high profits differentiation strategy in China. Thermal and optical design problems despite relatively important, but have not yet appeared in the entire worldwide breakthrough solutions essentially. In other words, in the thermal and optical design aspects, the difference between China and foreign countries, there is no qualitative difference, various solutions are similar, the effect is similar to the corresponding patent influence binding than small, packaging and application vendors can only earn very low differentiation profit through each tiny improvement, which is the reason why the package and application vendors gathered in one of the main reasons.

In fact, one of the important feature of the high-tech semiconductor industry is through semiconductor micro processing technology, to let the entire products as much as possible concentrated in the upstream end of the chip, and left little to the middle and lower reaches of the technology space. Moreover, with the integration of the continuous improvement of this trend in the semiconductor industry, semiconductor-related high-tech industries will become increasingly concentrated in the upstream chip.

LED highway lighting: an over-fast development?

Currently, most of our highways are not equipped with street lights. With the introduction of LED highway lighting technology, experts expected a fast development of LED in this area. However, there are also some other people suspected that LED highway lighting industry was going too fast and worried about a deformed and unhealthy development at last.

 

Currently, most of our highways are not equipped with street lights. With the introduction of LED highway lighting technology, experts expected a fast development of LED in this area.

 

Mr. Junyan Xie, an expert from the street lighting field, indicated that: “LED highway lighting applications are far beyond where it expected and should be. I discussed with other experts and scientists in this part, we listed many advantages of LED highway products, but there still some disadvantages. In my opinion, before solving these problems, we should not promote such immature technology in the highway applications. This will increase the risk of accidents. ” Mr. Xiaoping Yang, a scientist from Beijing Institute of Electric Lighting Source suggested that it is infeasible for replacing all existing high pressure sodium lamps with LED lighting products. We should start with small roads and main roads. Highways will be the final step. After a certain period of development, when the quality and reliability of LED highway lamps can be ensured, it will be the time that LED lighting technology dominates the highway market. Mr. Yangsheng Chen, the chairman of China Association of Lighting implied that LED highway lamps may probably be pilot applied. It is not a right time to widely promote them due to the bottlenecks in technology and cost aspects.

 

Highways have their special driving requirements, especially in raining/snowing days. As we all known, high pressure sodium lamps have very high penetration, much better than White-ray LED lights. How can LED lighting applications competent in fog weather? Mr. Junyan Xie disagreed with the using of LED highway lighting applications. In his point of view, with current LED technology, LED lights will “totally be failed” in fog days. “That’s really dangerous for drivers.”

 

In the conditions of low-carbon applications having been supported in many countries and areas, safety is the most important factor in highway or other road facilities. Extreme weather conditions should not be omitted in the consideration of LED-related lighting applications. No matter how, it is the safety that most important than other factors.

Factors that constrained the development of LED highway applications

LED technology has a lot of advantages. But in practical, applications of LED lighting sources still have many restrictions, which have been the largest obstacles in the path of LED highway applications.

 

Factors that constrained the development of LED highway applications

 

1)       Heat dissipation.

Improving the heat problem of LED lights is always one of the biggest challenges for LED manufactures. The working condition and heat dissipation is the two major factors that can determine the real light efficiency of LED lamps and certainly the service life of them. Generally, when we discussed about the light efficiency of LED lamps, we were talking about the light efficiency with an junction temperature of 25℃. However, due to cooling designs and influences from surrounding temperatures, it is usually higher than 25℃ in practices. That means, in real applications, the measured light efficiency will be less than the theoretical value. A theoretically 100lm/W LED chip used in LED highway applications may only have a real light efficiency of 60-70lm/W.

LHP is an advanced cooling technology for LED lighting products which has been recently invented by a technological company from Taiwan. This technique was first invented to replay traditional heat sink, which has well solved the problem mentioned above and dramatically increase the service life of LED chips. In order to prove the superiorities of LHP, thousands of LED chips were selected to take a 3-year special aging test (light attenuation test). During these tests, selected LEDs should take constant work for 12 hours per day. After 3 years, the measured light attenuation was less than 3%. It is estimated that after 10 years, the average light attenuation of these chips will be only 20%.

 

2)       Cost-effective problem.

Presently, prices of LED chips were still in a high level, causing LED street lights cost much more than traditional street lamps. However, there are also some people believe that prices of LED lighting applications will drop into a much more reasonable level, for the reason that LED is a kind of semiconductor components and the continuous development of micro-electrical industry. At present, the highest light efficiency of LED chips is around 150lm/W. And it is estimated that after ten years, the light efficiency of LEDs can reach up to 350lm/W. Thus it can be seen that LED highway applications actually has huge potentials.

How does LED lighting industry become bigger and stronger (one)

Today, under the background of  energy shortage, environmental degradation, “energy saving” has become the main task of the Governments, and China is no exception.

How does LED lighting industry become bigger and stronger (one)

LED lighting technology by virtue of its high performance, long life and other advantages in energy saving, everyone touted the “superstar”. all levels of government spared no expense to support it, in order to “energy saving” policy; brightest investment and private capital investment directed as its “huge market” have pocket it; various research institutions have been “merry” reorientation aimed at it; Various civil society organizations also can not wait to be included in the scope of business. Especially after the global financial crisis, with the introduction of the scheme of the huge new energy plan of the new Obama administration in the United States and the Chinese government to expand domestic demand in most other high-tech industries hit by the crisis, the LED lighting industry seems “the scenery here is fine.”

However, the LED industry in China, the new darling of the beautiful LED lights, we should think calmly about the fundamental issues that the fundamental issues that overshadowed prosperity surface.

First, what is the core issue of China’a LED lighting industry?

From the application point of view, the main market of the LED is lighting, display and backlight. Display application market has matured, the back light market is maturing. Greater than the impact of these two aspects of the market by the financial crisis. However, whenever from the government “energy saving” sense or potential size of the market from the point of view or from the direction of technology development visit lighting applications are deserved is the top priority of the LED market. This is why Europe and the United States national attention to the root causes of the LED technology. So, talk about LED in this passage, it also focus on the lighting market.

The core problem for LED lighting industry is not that the middle and lower reaches of the package and application, but in the upper reaches of the high-end chip. Imagine, if China has been the lack of high-end LED chip, even invested ten times funds in the demonstration project. That is only for foreign chip makers in China to earn more profits.
