LED lighting industry kept the two major misunderstanding

With the Copenhagen Climate Conference at the end of 2009, the world sounded the clarion call of the energy saving and emission reduction. LED lighting as a new type of energy-saving, environmentally alternative technologies quickly became the focus of the government, the capital, and the business community. According to statistics, Up to the end of 2009, Chin-ahas developed the world’s most important production base of LED lighting. Under the impressive achievements, LED lighting industry has its inadequacies and its misunderstanding. The author analyzed as follows.

LED lighting industry is lack of upstream core technology

As  LED lighting is of  energy-saving and environmental advantages, in recent years, statistics show that LED lighting global output annual growth keep 20% or more.China has launched a green lighting engineering, semiconductor lighting project, “Ten thousand ten cities” plan in order to push forward the development of the industry. In 2008, the total output value ofChina’s semiconductor lighting is nearly 700 billion.

However, according to the introduction of the Chairman Wu Zhen Yue, Shenzhen Han Tian Technology company, there goes that despite the current Chinese LED lights industry investment and production can increase to accelerate, The LED lighting production enterprises is over 3000, but 70% of which is in the concentration of downstream integration application link which is lack of upstream core technologies. Also due to the enterprise which is generally in small scale and lace of standards, the product quality is uneven.

He believes that many cities carry out the LED lighting demonstration and alternative project now, but the LED road lighting is also limited to the slip road to the district, the pedestrian street, a limited range of applications, especially LED lighting products of varying quality.

The high cost of LED lighting is a one-sided point of view

At present, there exists a misunderstanding on the Social LED lighting industry. That is considered “LED lighting is a new technology, and it is certainly of high cost” which make LED lighting urgent breaking popularity in the domestic market.

Traditional lighting methods require the laying of the cable, which is the cost of a lot of money. At the same time, the life of the traditional sodium lights is short, generally lamps need to be replaced in a year or so, and late repair and maintenance costs are high. If these costs are considered, The cost between the LED lighting and the traditional sodium lamp is not too much.

Russia will be “New World” of China’s small and medium-sized architectural led lighting enterprise

LED companies in China was closed by the mainland market “internal problems” and “foreign aggression”, numerous large LED lights companies began to shift attention to two aspects:

One, try to get government grants, and try to support the market opened that day;

Two, more participation in government bidding projects to achieve business operations.

architectural led lighting

But the above two points are circles around the government regulation, and it should be the strength of the company’s games. The industry believes that, under the case of a market downturn, to open the Chinese LED market is the subject that many LED companies are facing, especially China’s LED lighting market. At the same time, China’s architectural led lighting industry should not just be a big companies’ world. Although standardized mass production era, small companies do not have a strong competitive advantage, while in some certain segments of the field, the big company will not be flexible than small company.

LED inside lighting market believe, for example,  the two most important factors are restricting Chinese LED lighting market are price and market awareness. Affected by the awareness of the architectural led lighting market, China’s township and rural markets is still a “ruins”; urban lighting market restrictions by fluorescent lamps, it is also difficult to develop.

For the enterprise development center, the industry also gives a different view. Neo-Neon China CEO Mr. Chen Yueming said, thanks to the well-developed network platform, today’s market is different from the past. He said that the opened form of  LED lighting market is less and less important, while the value of the product itself is the fundamental driving force of enterprise development.

The Linsen said, to meet the practical use is the key LED R & D. According to the needs of the practical application of the product, we need to refine of R & D and production, which can reduce costs, in order to guide the sales prices fall, the market can get further open.

Many industry experts also gives his own views, and they believe that the projects in the pipeline is also a way for architectural led lighting market, but the requirements of the product is very high, and need the support of the engineering and technical aspects.

LED lamps causes of damage

To take high-power white LED as a new green lighting, it will have many advantages such as light conversion, high efficiency, low power consumption, long life, no maintenance, etc. And thus it gradually used in a variety of lighting in the field. The long life of the LED is based in the safe working environment. As far as LED lamps china lighting is concerned, there are two factors affecting the life. One is the over electric shock which is applied to the LED on the current exceeding the maximum rated current of the LED technology in the date sheet, including over-voltage caused by over-current shock; Another is overheating damage. Damage can be expressed as the immediate failure of the components and it may also occur through electric shock after the incident for a long time before failure and to shorten the working life of LED.

LED lamps china causes of damage

LED lights failure first from the power supply and drive failure, the second is from the LED assembly failure. From the input power, it is usually damage to the LED power supply and drive through electric shock(EOS) and the load side of circuit failure.

LED components failure

  Transient over-current events is the maximum rated current flowing through the LED current in the LED lamps china technology data sheet, which may be the direct result of the large current or indirectly due to the high voltage generation, such as transient lightning switch over voltage event of power transient switching noise, power fluctuations caused by over current. These events are transient, very short duration. we usually referred to as spikes, such as “current spikes, voltage spikes. The transient over-current is caused by LED connected to the transient over-current power or hot plug.

LED lighting in the car, ISO7637-2 transient load-dump surge impact, it is a major threat to their normal work.
LEDs subjected to electric shock after the failure mode is not fixed, but will usually result in damage to the welding line. This damage is usually caused by a great deal of transient over-current, which will cause weld lines blown and may also lead to other parts of the damage near the welding line, such as sealing materials.

Cross-strait LED manufacturers called for the creation of a common brand

Cross-strait LED artery bypass meeting will be held recently, Taiwan and mainland China LED manufacturers industry heavy weights gathered, and the completion of a “cross-strait cooperation and pilot show, LED lighting technology norms and common standards and application technology research and achievements in Shanxi lighting demonstration Harbin in Cold reliability of semiconductor lighting research achievements demonstration “3 Letter of Intent signed.

LED manufacturers

Deputy Director of the National Development and Reform Commission, Central Information Secretary Lu McCain said, From July, the mainland should first ban on the import, production and sale of high-powered incandescent, then ban extended to small power incandescent energy saving. In 2015, we can do the final assessment. If the effect is good, mainland China since October 2016, will prohibit the import and sale of more than 15 watts of incandescent light.

The cross-strait LED industry bypass meeting will have a breakthrough development. The continent will unite Taiwan and India, Russia and other countries to uniform LED manufacturers lighting standards and specifications. The meeting further expand cross-strait LED pilot cities. At the same time, the two sides in the industry reach a consensus on the establishment of cross-strait LED lights common brand. We expected that agency in personnel  will come to Taiwan for further discussions on the mainland.

The representatives of the people in Taiwan said, the above significant measures will make the continent lighting market to re-shuffle. Therefore, if the continent is scheduled implementation as it is expected, it will bring Taiwan LED lighting industry a favorable foundation for the development. Technical cooperation from the bypass plan cross-strait LED industry is expected to deepen a equity cooperation, through the joint venture shares of the LED lighting industry, we hope that it can create a common brand, like the “China card” lighting products.

It is understood that the mainland LED manufacturers technology catch up with international companies within two years. Right now, it can offer LED lighting package components with 130 lumen per watt . In order to promote energy-saving LED products planned for this year, The Countries plan to let the Ministry of Finance allocate 2.2 billion yuan, within one year period to promote energy-efficient lighting products. Among them, There are about 10 million down-lights and spotlights to promote LED indoor lighting products, and about 1 million street lights and tunnel lights to promote LED outdoor lighting, which are installed primarily include industrial and mining enterprises, hospitals, schools, railway stations, airports, docks and roads and other important places.

There is future to invest in high-end LED lighting modern

In recent years, LED technology is widely used in the field of lighting modern. Other LED industry is also quick to become popular. However, many companies are lack of lack of competitiveness in technology, and the expected profit is not high. A lot of capital into this market will inevitably result in profits diluted which will cause disorder competition industry this year.

lighting modern

Many industry experts also said that the LED industry has turned out the signs of overheating which need to be alert to the problem of excess capacity; Another strong entry of foreign giants, domestic manufacturers should speed up in the new round of competition in technology development and patent protection.

It may overdraft the next 3 to 5 annual production capacity

On February 2, the first batch of new industrialization demonstration base award which optoelectronic industry base occupy three seats and LED industry has become a key industry of national development. At the same time, LED initial investment of 100 million yuan can plant low threshold, and stimulate launching LED project.
Public data shows that the total investment budget of LED lights project launched all over the country has exceeded the LED project has a total r 20 billion yuan in the first half of 2009 alone.
In 2009, the domestic LED enterprises have announced the financing to expand production.

In addition to the replenishment of expansion, public financing has also become the urgent needs of the development of lighting modern business. According to the National Torch Plan Key High-tech enterprises in Guangdong Country Star Power (hereinafter referred to as the country star power) had told the media that the company has submitted the application for the listing of small plates, waiting for the Audit Commission.。

According to expert analysis, from a statistical point of view of opened construction and planned construction projects, the production of the LED can at least overdraft the next three to five years of production and the market. After a large number of LED projects are completed, lighting modern industry will be overcapacity, disorderly competition in the market, lack of talent in China.

The using of Solar power low voltage LED lights have great potential in western area

World concerns about the security of energy supply and action to address climate change promote the rapid development of renewable energy technologies and industries worldwide, such as photovoltaic, wind power generation in the annual growth rate of more than 20%. Renewable energy has become an important alternative energy to diversify energy sources to address global climate change and achieving sustainable development.

low voltage LED lights

The energy-saving advantages of the solar lighting

With the economic development, China’s electricity for lighting will greatly improve the research and application of green energy-efficient lighting and appeal more and more attention. Solar low voltage LED lights as a cold light source products, is with a higher cost, green, safe, reliable, stable quality, long service life, easy installation and maintenance features, and can be widely used in green lighting, road lighting, advertising light boxes lighting, urban landscape modeling lighting and home lighting systems, solar LED lighting, one-time investment in higher development bottleneck.

At present, lighting consumption is about 20% of the entire electricity consumption. Reducing lighting electricity is an important way to save energy. To achieve this goal, the industry has developed a variety of energy-saving low voltage LED lights equipment, and achieved some certain results. However, the requirement is also far from the “green light”, the development and application of more efficient, reliable, safe, durable new light is imperative.

By the end of 2006, China’s renewable energy capacity total 200 million tons of standard coal (excluding traditional biomass), accounting for about 0.5 percent, which took a solid step  on the achievement of the renewable energy accounting for 10% of the national total primary energy consumption. At present, China will promote the development of the domestic PV market according to the following ways: First, Starting sending electricity to the village of Engineering; Second, Using the photovoltaic power generation, such as the World Expo, Olympic Games; Third, Building PV power plants in the desert; Fourth, the mobilization of some cities to start roof plan; 5, Studying to improve the competitiveness of PV tariff policy

In western China, the non-trunk solar lights, solar garden lights gradually become certain scale. With the vigorous development of solar lamps, the “green light” will become a trend.

Three major trends in domestic lighting industry

April 10 to 12, organized by the China Illuminating Engineering Society, the Free Trade Association International Exhibition 11th Beijing International Lighting & Electrical Expo opened in Beijing China International Exhibition Center, the exhibitors of the countries and regions participated in this event. Architectural lighting sector dean Professor Zhan Qing Xuan, electrical chief engineer of the Institute of Architectural Design, Tsinghua University, Beijing Illuminating Engineering Society, chairman of Dai Deci, chief lighting designer of the Hao er sai, talked in an interview with this reporter, from light pollution to green lighting, the monomer architectural lighting to landscape lighting, the coastal markets to the Mainland led lights market, is the three major trends in the lighting industry.

Three major trends in domestic lighting industry
The first trend is from the lighting pollution to green lighting. To this, Professor Zhan thought that” poor design as there is no design”. He clearly pointed out that “good lighting design should make the lighting and architecture complement with each other, and lighting should be against the background of architecture and landscape rather than show off their own.

The second trend is from light pollution to green lighting, the monomer architectural lighting to landscape lighting. At present, urban landscape lighting emerged out of the Bund in Shanghai, Beijing Olympic Park and some outstanding urban landscape lighting project through remodeling the image of the city at night by lighting.

The third trend is the vast western market to be the next focus of the lighting industry. The development of western China is put forward for 10 years, more and more overall strategic framework of the Shaanxi and Gansu Guanzhong – Tianshui, the fulcrum of the Beibu Gulf in Guangxi and Sichuan, Chongqing, three regions, which Guanzhong – Tianshui Economic Zone Development Plan by the State Council approved in June 2009, which provided an” experimental field” for the economic takeoff of the China’s west region.

Senior lighting designer Ren Jian said: With the latest strategic plan of the country’s western development, we have been deep into the group of cities in Shaanxi, Xi’an, Hanzhong, Xianyang, Baoji, Weinan, and disseminated the international front design idea, and also introduced the urban landscape lighting, commercial lighting and bridge lighting experience to practical action to support ‘Guanzhong – Tianshui Economic Zone’ development, in order to contribute to the country’s western development strategy. “

“Four in One” walk the road of LED lighting industry

As LED lighting industry is of huge potential economy and social benefits of LED lighting industry, all the countries around the world attach great importance to the R & D and production of LED. Advanced countries promote the rapid development of the semiconductor lighting industry from the technology, industrial policy, industry standardization promotion, and the cultivation of “four in one” consumer environmental philosophy. This has a certain reference for the development of LED industry in China.

LED lighting industry

Ensure the technology first.
LED lighting industry as an emerging industry has many major technology research. However, technology research  with vast investment, long cycle, huge risk can not just let companies invest alone, the government participation is also very important. Only this way can promote the technology development.

In June, 2006, U.S. Department of Energy’s decide to support the five major LED lighting project : Listed as below: general lighting with integrated LED floodlights, solid-state lighting products, higher light rate of phosphor-based white LED phosphor systems, organic semiconductor lighting device structure, the durable and efficient the hole emitting diode. The total investment of the five projects is of $ 11 million. The main source of funding is main to government investment, accounting for 70%, the other 30% of the funds is invested by the enterprises which is responsible for developing the project.

When the LED lighting industry is rising, Chinese companies missed an opportunity to overcome the major technical problems. Many of the core technologies are occupied by foreign enterprises and some related enterprises in China seem somewhat passive. China’s LED industry how to break through the technical weakness needs the efforts and explore of the parties.

The LED industry has a huge economic and social benefits, many countries have introduced a related industry support policies, including special fiscal spending, tax incentives to encourage R & D and investment in the LED industry, and the establishment of a sound system of LED lights industry.

In recent years, China has also introduced a lot of industry support policy. Insiders pointed out that the Government should give more consideration on how to make the utility maximization policy support, and to avoid wasting resources.

led lighting bulbs basic research need to be strengthened

Semiconductor lighting industry has become the industry heights of the post-crisis era. For basic research in Chinalags behind the technology, market development phenomenon, experts called for.

Due to the huge application requirements, the semiconductor led lighting bulbs market appears market leading technology development, technology research ahead of the characteristics. Recently, the basic research on relate topics held at Xiangshan Science Conference, Nanjing University Professor Chang Yung and other experts pointed out that China’s semiconductor lighting basic research received certain support in the past 10 years, but there still exists absence. The early accumulation of the basic research cannot adapt to the rapid development of the semiconductor lighting technology needs. Thus, accelerating the study of a lot of basic scientific questions of the semiconductor lighting technology and solving the technical bottleneck of industrial development is imminent.

led lighting bulbs

Semiconductor led lighting bulbs, are widely regarded as the second revolution of the lighting in the history. Luminescence is completely different with the traditional lighting. It is not only with a safe, no strobe features, but also there is no infrared and ultraviolet radiation which does not cause two secondary contamination. “the Chang Yung introduction.

“According to the theoretical expectations, semiconductor lighting luminous efficiency can reach 400lm / W which is 3-4 times compared with the expected efficiency of energy-saving lamps.” Researcher Zeng yiping at the Institute of Semiconductors, analyzed that: If the semiconductor led lighting bulbs source luminous efficiency 200lm / W or more, it can replace our traditional lighting source which can at least make our country lighting electricity annual savings of more than 1/3.

Reporters learned from the meeting, the current level of international semiconductor lighting products has reached 100lm / W, and the level of our industry has more than 80lm / W, which is over luminous efficiency of led lights.

“In China, We should strengthen our support in the field of basic research ” Zhang rong said that currently 100lm / W luminous efficiency to 200lm / W, the efforts of a number of years, basic research needs to be further breakthrough. “

Dongguan will build a complete LED lighting industry chain in 2015

The author received the news from the Dongguan Municipal CPPCC Economic Commission yesterday that Dongguan LED industry chain is to speed up the layout for intentional introduction into the LED industries of Taiwan-funded enterprises to join. By 2015, Dongguan basically built a relatively complete industrial chain of LED semiconductor lighting, gathering more than 200 enterprises of LED lighting which the annual output value is up to
150 billion.

Dongguan will build a complete LED lighting industry chain in 2015

At present, China has formed the Yangtze River Delta, Pearl River Delta, Fujian Triangle, as well as the northern region LED industry gathering area. Dongguan is the important city of the Pearl River Delta LED lights. Ministry of Science and Technology officially identified the “city of ten thousand,” semiconductor lighting demonstration project as pilot cities. According to statistics, the city engaged in LED lighting industry technology and production enterprises is over 60, and the sales income is more than 20 billion yuan.

CPPCC Economic Committee of Dongguan City, actively and steadily promote the development of LED industry in our city, “” believe that the development of Dongguan LED industry is extremely uneven. The city’s LED industry is over-concentration in the field of industry chain downstream under the constraints of the technology and cost. Besides, LED enterprise is lack of concerted effort because of fragmentation. Therefore, Dongguan has established the major group of promoting LED industrial development and demonstration and try to solve the big problems of LED lighting industry application process.

In addition,Taiwan is the place that LED industry development is earlier which highlight the advantages of the LED industry chain. Dongguan is the largest city gathering most Taiwan-funded enterprises. Dongguan City CPPCC Economic Commission believes that it should reply on the Association of Taiwan enterprises in Taiwan to further promote the cooperation between Dongguan and Taiwan in science and technology. And take the initiative to introduceTaiwan’s key LED enterprises, especially upstream epitaxial chip preparation companies.

In addition, CPPCC Economic Committee of Dongguan recommends that relative enterprises should be organized to build the LED Industry alliance by establishment of the LED industry associations.
