The cold thinking of the prospects of Sino-Japanese LED future lighting development after Diaoyu Island incident

Around the Diaoyu Island incident, which the Japanese government want to “buy” it, Sino-Japanese relations are pushed to the cusp. Both the political and the military and civil are in the intensive position. The incident indicates that Sino-Japanese relations may be the secondary fell ravine since the normalization of diplomatic relations.

Under the domestic political and social pressure, China take counter-measures is inevitable. The Sino-Japanese friction is caused by the Diaoyu Islands issue. The future core will be around the actual control over Diaoyu Islands. If the counter-measures can make Japan on the the so-called “actual control” Diaoyu Islands bathing, that China will be a major achievement. More likely, the two sides stay in the “cold stalemate” and” cold confrontation state around the Diaoyu Islands. The two sides show “light muscle” each other and even occure “physical contact” class ocean surveillance ship collision, but it may not develop into a military conflict.

If the Military conflict is temporarily impossible, it is more possible that the counter-measures is economic sanctions, which is more viable than the military conflict, and the impact will be larger and more lasting. Japan Canon’s global strategy, research director of the Institute Seto mouth Kiyoyuki admits: the most worried about is that the Chinese Government is considering the restricts of economic policy. If China really started to economic sanctions against Japan, how deep the impact will be in the LED lights future lighting area?

At first, Sino-Japanese trade will be greatly affected. Since 2007, China became Japan’s largest trading nation. Today, China still remains the largest future lighting trading partner of Japan, the largest export market and source of imports. According to the statistics of the Japan External Trade Organization (JETRO), Japanese trade volume in 2011 reached $ 344.9 billion, of which $ 183.4 billion of imports from China and Chinese exports of $ 161.4 billion;

Second, China holds a large number of Japanese government bonds.According to the Japanese Ministry of Finance, Japan’s central bank announced the international balance of payments statistics show that the amount of Japanese government bonds held by China is rapidly expanding, the holding reached the highest in the history of the 18 trillion yen up to the end of 2011, representing an increase of 71% over last year.

Third, the Chinese travel to Japan may be substantially reduced.

Fourth, China is an important investment area in Japan.

Fifth, the strategic resources is also capable “economic card” to restraint in Japan.

Foreign render intensive hunters shows the situation to copy of China’s LED industry(2)

Local industry crisis of the post-crisis period

Industry consolidation, mergers and acquisitions and restructuring are the market behavior. But in the shorter cycle, so intensive penetration of China’s semiconductor LED industry are the first time to appear.

The dense infiltrate behind reflects the plight of the current development of China’s semiconductor industry, and that too much emphasis on the low end of the scale of the development of the situation, and will eventually be replaced by more innovative strength pattern.

Over the years, with the huge market demanded, China will soon become the world’s largest semiconductor market. Local semiconductor LED industry, from the beginning of the last century, has experienced rapid growth of nearly 8 years since 2000 (an average annual growth rate of more than 30%). They have a complete industrial chain in the design, manufacturing, packaging and testing. Moreover, each of the sessions have a large number of enterprise groups.

For example, semiconductor design companies in China had reached a maximum of 500. Manufacturing companies from 2006 to 2007 planning project has reached 20. Relatively strong packaging and testing LED lights industry, there are Changjiang Electronics Technology, through rich micro electric Huatian nearly 10 enterprises.

To Embarrassment, the output value of each link, are not as large-scale overseas with the aspects of an enterprise. For example, 500 design enterprises output value is not as good as had Mediate ranked 10 in the world, all OEM enterprise output value is not as good as TSMC, ASE. All packaging and testing enterprise value is inferior.

The financial crisis tender this situation. Chinese Academy of Engineering, said Xu Juyan, continent of the world’s fastest growing market in 2007, after the onset of the crisis, has become the fastest growing area of the global rate of decline. In 2008, China’s semiconductor LED industry for the first time emerge a the historic negative growth.

“In this way, the integration process is inevitably important scale corporate body is more important.” The Xu Juyan on the “First Financial Daily” said, operators need to enhance physique like SMIC, shifted from the pursuit of scale to the pursuit of profit.

Gu Wenjun said that the current market demand are larger than the production capacity, and that transfer capacity of foreign-funded enterprises in China. It is natural to use the capital, direct acquisition of better factories time.

Foreign render intensive hunters shows the situation to copy of China’s LED industry(1)

“In 2008, we exclaimed to copy other people’s ‘bottom’, but the results has no action, and now people to copy us.” Yesterday, the semiconductor industry expert Gu Wenjun “First Financial Daily” said.

Within six months, the foreign hunters situation of China’s LED lights industry semiconductor industry is intensive rendering.

However, in the past year, more than the integration of the semiconductor industry, such as Chartered Semiconductor, Qimonda, Spansion, Sony, Sanyo Semiconductor case, which has acquired Qimonda Da Xian design base, in addition to the Shandong Langchao Chinese LED industry enterprises of any figure. Originally, Godson had tried to buy MIPS, but still stay in the conception stage.

The overseas capital intensive penetration of the local semiconductor industry

“First Financial Daily” give a rough statistics, the case of the recent foreign penetration of the local semiconductor companies hav at least four.

Including: the American Silver Lake Capital incoming Spreadtrum has become the second largest shareholder by action; TSMC claimed 10% stake in SMIC (Morgan Stanley to participate in the rights issue has become the fourth largest shareholder); MediaTek borrow overseas investment funds curve White TD design enterprises in Suzhou Fate; Texas Instruments is operating the acquisition of the SMIC original custodian factory Chengdu Cession semiconductor.

Spreadtrum, SMIC were Silver Lake Capital and TSMC Morgan Stanley successfully into the Bureau, is fueling market correlation effects; while Fate case, its original investor letter the Rainbow investment company who confirmed the sale of newspaper. This is a cycle before, a chip design companies have acquired local phone chip design enterprises Chip nuts core business.

“There is a larger case, TSMC, and Micron Technology in the United States talks with Xinxin Semiconductor who intends to acquire.” Sources disclose exclusively on the “First Financial Daily”.

TSMC backing need not to say. The world’s largest LED industry semiconductor companies occupy more than 50% share of the foundry market.

The people said that at the beginning, TSMC determined to win, the two sides even signed a cooperation agreement. But at last, Wuhan suddenly rejected the transaction request. The TSMC’s acquisition movement, did not pass the hurdle of the National Development and Reform Commission. Micron Technology, now and quietly contact with Wuhan. Micron Technology, the U.S. flash memory giant, is also behind the obstruction by blocking the SMIC application case of the U.S. Export-Import Bank loan of $ 750 million in 2007.

Russia will be New World of China’s small and medium-sized architectural led lighting enterprise(2)

Rectangular lighting said, the future development direction of architectural led lighting is the field of lighting design. The rectangular thinks that the part of light source part (LED illumination finished) is for replacement -type civil market.It is difficult to make a difference.At the same time, the meaning of of light source part difference is not big.

Small LED enterprises in the Chinese market, LED inside editors think that identify the market position and doing fine and stronger single product more suitable for the development of enterprises.Some enterprises should also identify the target market. LED inside reporter visited the market and found some small LED enterprises in Shenzhen earn sudden huge profits just by export LED lights ,3WMR16 LED Spotlight to South Africa or India.

LEDinside think that Russia formally joined the WTO today.The import tariffs had somewhat reduced recently, forward to continue to decline
, bring new trade opportunities will extend far beyond the digital manifestation.In the low-end export enterprises of LED lights can go to Russia to see .The current pace of development of the Russian LED lighting market, the Russian architectural led lighting market is likely to become the “New World” of China’s small and medium-sized LED business.

Mood lighting is a flexible, interactive, dynamic lighting use, state-of-the-art lighting technology, bring changeable, clever lighting environment, it is not only energy-efficient and easy to operate, and the consumer’s shopping experience into sensory enjoyment, in order to stimulate sales.

The LED commercial effect is also an increasing number of businesses, which is a recognized data. Last year, Eneltec in the LED business growth gained more than 100%.

In fact, LED widespread use has become a trend, the current incandescent gradually withdraw from the market, and fluorescent will be put in place in a short period of time and in the field of commercial lighting and LED and other appearance on the same stage. Due to the use of mercury in a disused that will pollute environment, so to replace LED fluorescent lamps is inevitable, a great change has quietly begun.

In New World Department Store, one people said, in today’s competitive architectural led lighting business, it is not just the icing on the cake, sometimes boon.

The innovative storm promote LED commercial lighting model change(2)

In the development of innovative lighting technology, lighting can not only enhance the brand value of the store itself, but also create a unique shopping experience for customers, and can change the lighting effect which is far more simple than the improvement stores.

LED is a huge change to business marketing model and shopping experience. Previously, Philips Lighting Division and the Netherlands, a company called Hepplewhite supermarket joint an experimental period of 21 weeks. Layout different LED commercial lighting solutions in the Market place to measure the different colors of light, what kind of impact the tone on consumers buying habits.

The Study found that since the LED lights can achieve different light color, the guest under the influence of light are more willing to consumption, rational distribution of the different color lights in the store can therefore be increased by 2-5% of sales. The experiment also found that consumers bright and warm color lighting environment can be 8% of the time, in this environment, consumers are more willing to choose a different path selected items, the mood will be more pleasant.

“Change is obvious.” The MASSA architectural design firm under Ma Xiaowei said, he has a deep impression of Philips Smart Bright bright LED Down light. In his view, the down light has a flexible plastic, adjustable color temperature apply to present a variety of goods, Smart lighting of commercial space, and ultimately serve the customer, “from the use of Smart Bright bright LED down light effect lighting has played the role of the shopping guide and enhance the product in light of the customer attraction, having a certain extent, to increase product series of competitive and help consumers to make decisions. ”

The LED commercial lighting differ based on the different places relatively concentrated flow, general, sales of fast moving consumer goods in supermarkets, color temperature, brightness should be higher, so that people become excited, faster and more selection of products; luxury stores want consumers to stay more time, so store lighting tone is warmer and softer, people will feel more relaxed and feel good.

Eneltec Group is the first to put forward the the AmbiScene scene lighting. This is a gorgeous face lift lighting for shops innovative lighting concepts and solutions, in the development of innovative lighting technology, lighting can not only enhance the brand value of the store itself, but also to create a unique shopping experience for customers, and to change the lighting effect is far more simple improvement stores.

The technology innovation for led low voltage lighting

LED with low power consumption, the extraordinary life has been widely applied to the signal indication, digital display and other weak areas. However, because of the traditional LED light source opening angle is small, the scattering of light is of high direction and easy to form a spot light uniformity and other factors, the shackles of its application in the field of lighting.

With the update of the traditional solar lighting structure, the intelligent controller, the angle of light reflection and technological improvements, the optimal tilt angle design is best made which can let it more uniform light, overall brightness, lower cost and also good to promote.

Through the reasonable control of the flat head high brightness white led low voltage lighting installation angle, Flat head LED lights column and the torch-the combination light structure made the LED combination of light emitted by the uniformity of the illumination light and illumination to be increased dramatically. The technology not only strengthen the light effects, but also about 4W combination of light energy emitted by the brightness of the light up to 20W energy saving lamp or 40W incandescent brightness can be a more effective use of solar energy.

The combination of specially developed for street light field light source – cross-shaped and rectangular combination light source, give full play to the advantages of flat head LED opening angle optical uniformity and high brightness round led low voltage lighting point area.

The controller, through the technology of solar photovoltaic, maximizes the energy collection. 12V DC power supply to the light source to provide the energy reserves, the battery, the light source produces a 6500K white light. At meanwhile, through the streamlining intelligent controller, the structure is more simple and the failure rate will be low.

The promotion and application of the solar lighting
Solar energy as an emerging green energy is in the rapid popularization and application with its unparalleled advantages. As a fourth-generation light source, solar lighting is used among the city beautification lighting, road lighting, garden lighting, indoor lighting, as well as other areas of lighting. Especially in remote areas without electricity, solar lighting will have a more broad application prospects.

The study on led outdoor lamp heat sink design

Because of the complexity of the work environment of the outdoor lighting, subject to the influence of temperature, UV, humidity, rainy day, rain, dust, chemical fumes and other natural conditions, the serious problem of the LED light failure will be caused. Therefore, taking the above factors into consideration, the outdoor lighting designers should consider these external environmental factors for the LED outdoor lighting when the outdoor lighting designers do the design.

Here, we would like talk out the study on the outdoor LED lamp heat sink design

The radiator is a very important part of the LED outdoor lamps which its shape, size, heat dissipation surface area should be designed to be consistent to the benefits. The luminous efficiency and life is affected by the high operating temperature of the LED light. The radiator is too large which will increase the consumption of materials and the product cost and weight and it will make our products competitive decline. Appropriate design led light heat sink is essential. The radiator design has the following sections.

1, A clear LED outdoor lights require cooling power.

2, Some of the parameters used in the design radiator: the metal specific heat, the metal thermal conductivity, chip resistance, thermal resistance, ambient air thermal resistance, ect.

3, The use of the scattered type ( natural convection heat strong wind cooling, heat pipe cooling, as well as other thermal cooling way). From the cost comparison: natural convection cooling cost a minimum, strong winds, the cooling medium, high heat pipe cooling cost, jet cooling the highest cost.

4, to determine the maximum permissible operating temperature of the LED lights (ambient temperature plus temperature rise permitted lamps)

5, Calculate the size of the radiator, cooling the area and determine the shape of the radiator.

6, Combine the radiator and LED outdoor light into a complete lighting and power more than eight hours at a room temperature 39 ° C – 40 ° C environment, to check the temperature of the lamp to see if it meets the cooling requirements in order to test correctly. If it not meets the conditions of use, it will have to recalculate and adjust the parameters.

The representive of NPC strongly suggest to develop energy-efficient lighting industry

HU Changsheng, NPC deputy and mayor of Suining City, Sichuan, said that the reform and opening up 30 years, China has made great achievement in increasing energy saving as the main structural adjustment and technological transformation efforts, energy, water and resource conservation. With the rapid economic development, population growth and the improvement of people’s living standards, the macroeconomic performance in resource constraint contradictions have become increasingly prominent, and tight resource situation also became increasingly prominent.

In recent years, the semiconductor lighting industry has developed rapidly. The United States, Japan, Europe, South Korea and China’s Taiwan region has strong advantages in different areas, and t he global output annual growth rate maintained at more than 20%. After 30 years of development of LED industry in China, it has initially formed a relatively complete industrial chain including epitaxial wafers, chip preparation and packaging, as well as the application of LED lights. Although China has become the world’s largest energy efficient lighting products manufacturing base, however, industry concentration is low, and domestic market share is limited, even a considerable part of the business just OEM production.
At present, under the tension power resources of our country, about 14% is consumed in various areas of the lighting. To this end, China has started a green lighting, semiconductor lighting project. The State Council set up a special team of energy conservation and emission reduction. Since 2008, 150 million energy-saving lamps are spread across the country in three years, 50 million a year; Residents purchase the promotion of energy-saving lamps, state subsidies by 50%, the bulk of customers to purchase, state subsidies of 30% .
In order to further promote the development of efficient lighting energy and efficient lighting industry inChina, and also to accelerate the pace of western efficient lighting industrial bases, HU Changsheng hereby submited the following recommendations:

Make out the construction of supporting regulations and standards “Energy Conservation Law” as soon as possible. Such as “energy monitoring management approach”” the state organ office buildings and large public buildings indoor temperature control approach ” “high-energy special equipment energy-efficient supervision and management measures “,and so on in order to further enhanced the operability.

The prospects of LED commercial lighting

LED commercial lighting is very popular, how its prospects for future development will be?

We can analyze from the following levels:

First, from a technical level: LED commercial lighting owns more advantages than the traditional commercial lighting.
Used in traditional commercial lighting fixtures includes incandescent, halogen, fluorescent, energy saving lamps, metal halide. Compared to these traditional lamps, the white LED has five major advantages: 1, energy saving, LED commercial lighting is generally only 1 to 10W low power consumption. 2,environmental protection, LED recycles light, But energy-saving lamps, halogen lamps has a major recycling problem as all these lights contain the pollution of the environment of the metal elements (such as mercury). 3, security, LED light fever is not high; 4, long life, 5, the luminous efficiency and changeable color. 1W LED lamps can usually reach 90-100 lumens, equivalent to a general light source 5-6 times the light efficiency.
Second, from the market level: the prospect of LED commercial lighting market is broad.

1, the R&D cost continue to decrease.

LED’s core technology is the LED chip technology. With the thawing of the LED chip technology patents after 2010, the prices of the LED chips decreased substantially and so did the cost of the LED commercial lighting products. It will be a happy event for the LED manufacturers as it will improve their enthusiasm for production.

2, Brand is slowly rising.

3 , the application environment has become increasingly public.

In fact, LED commercial lighting concept has become vague and some products are no longer limited to high-end commercial spaces.
4, The channels gradually approach the traditional business.

At present, LED commercial lighting promotion mainly reply on the model of the traditional business of commercial lighting channel.

Through the above analysis, we can see that the LED commercial lighting will tend to be more and more mature in the future. The stability of the LED products will be enhanced further. To the people who are in LED field, the inexpensive, high-quality LED lamps are the key development for the LED commercial lighting. In short, a LED commercial lighting war is inevitable. Emerging brands, export sale brands will be the leading force of leveraging traditional domestic business and also the mainstream of the commercial lighting.

The large scale application of commercial LED is not a dream

In fact, it is zero investment and zero risk for our mall. The LED down lights manufacturers is of warranty period of three years. Within three years, the light fades should be controlled less than 20%. If it is over 20%, you will enjoy a free replacement. Theoretically, the commercial LED lamp life can reach 50,000 hours which means that it can use over a decade. Conservative speaking, it can be used for three years now. Year and a half section of the rest of the electricity can be used for costs, as well as earnings in a year and a half.” Chen buggy analyze the economy of the large scale application of the commercial LED lamps from the vision of a businessman.

In Hefei, the reporter saw that the second, third, and forth floor of Qingyu clothing mall use the commercial LED lamps for lighting. Times Square in Hefei, Anhui manufacturer have entered the installation phase and plan to completely transformed into the semiconductor lighting step by step. Hefei Times Square Engineering Manager Zhou Dongjun said: “After comparative testing of semiconductor lighting and traditional lighting, energy saving is up to 75% or more.”

In addition, the reporter saw the field of semiconductor lighting of the the Hefei airport terminal building, 9.5 meters high waiting hall showing the rich texture of the light intensity. According to reports, this is the world’s first airport terminal semiconductor lighting Civil Aviation Airport. Another case is located in the Economic Development Zone of Hefei Jade Avenue and Danxia Road Interchange Jinshui, fairy gardens to residential real estate in the heart of University City. This item was included in the “Eleventh Five-Year” National Science and Technology Support Program, which is an integrated system engineering, solar photovoltaic, green lighting, semiconductor light source applications, fire emergency lighting, network management, infrared alarm monitoring, digital system control and more items integrated high-tech, solar public lighting electricity. The project is saving lighting 111 million kWh / year. This project uses a semiconductor performance lighting technology, energy-saving basis up to 50%, a 95% reduction of the total energy consumption through the use of renewable energy.
