The boom season of led lighting market and warm for inventory to run away

Inventory is the reason for some people running away with money.

Much more small business owners run away in the bad industry base. Chang Ling tells a reporter, lighting industry is weak in this year, most of LED lights enterprises will be more careful when they chose who should be cooperated. They are trying to consider the brand. Those people who run away is just they didn’t have much order, but they still place the order with other factory, so as to there are many inventory in stock. Due to the financial deflect, time for them pay salary and pay balance for the factory, they run away without telling their workers.

The boom season of led lighting market and warm for inventory to run away

At present, boom season of led lighting market come again, it’s also the peak season for customer place order. Some related department from government place an close attention to they, as to they are afraid to run away this time.

That’s why Inventory became the only ” life-saving straw “.

Five major causes of falling sick from overwork

One of the biggest advantage of the industry cluster base is rich and complete industry chain resources, but it does not mean that the industry chain can consciously maintain a healthy and stable. If farming conditions deviate from this, it should be the “Autumn Harvest” season, but not the only brilliant gold and silver, it will also make the industry reshuffle funds strand breaks haze. According to the summary of the investigation by the reporter, the six etiology in Guzhen mature industry cluster base “overwork” and “on foot-shuffling” symptoms today:

A homogeneous enterprise are too dense

Industrial cluster effect for the production of similar or even the same product  spring everywhere in enterprises, over-centralized, resulting in serious homogeneity, enterprises for the sake of accessing to low-cost, high profit at all costs. According to incomplete statistics, Zhongshan size led high beam lights  lighting market business have over 2000, but really less than 10% of the brand awareness.

Access standards are not standardized

The government, At the same time, made a lot of mercenary, but only glimpse the opportunity to fish in troubled waters, plus the rent-seeking business prospered, the owners only see the immediate benefits, to reverse this trend “free enterprise” the “undocumented outlets quietly breeding.

The boom season of china LED and warm for inventory to run away

The lighting industry traditional cycle is not so good recently year. From the logistics transportation data can be seen, Zhongshan lighting industry of domestic total sales year-on-year decline nearly 30% in this year. Qin Yue logistics chairman Feng Jianzhong said to the reporter, he also reminded the industry reshuffle, enterprises should pay attention to capital chain and safety risk.

The boom season of china LED and warm for inventory to run away

According to the reporters visited several professional lighting logistics transport company, the responsible person said: this new customers ( distributors and enterprise ) amount is increased, but the average customer is in decline.

An original in a new white led  lighting enterprises to do marketing director said ” Even in the coastal areas, including Changzhou, Linyi, the wholesale distribution base,there didn’t have much opportunity in this as before. The terminal is lack of power, the order is not stabilized again, follow the trend of china led enterprises making it more difficult to do business in this line. “.
Reporters in Changzhou, Linyi and other research learned this from the Zhongshan Ancient Town, they would like to buy the led light from zhongshan directly and then assembly to OEM distribution dealers year-on-year increase locally. Thus, china LED light will become much more cheaper, so that’s the reason this industry become more and more hard than before.
” wholesale price of 3.8 rmb for 3 by 1 watt LED die-casting lamp, and wholesale price of 5.5 yuan for 3 times 1 watt bulbs ” This is the reporter visited the Zhongshan lighting street received some enterprise price leaflets on the visible content, which was crammed with more than 20 LED lights photos. The low price make people feel doubtful.

” Boom season is forthcoming, recently many china LED enterprises have benefit a lot from the led industry. Many people will come zhongshan for purchasing led light at this time of the year. But there are some enterprises have some bad thought. Crystal lighting chairman Chang Ling discloses to the reporter, some of the company and some people will run away once their customer placed the order with them, which cause great influence in this chain for a large number of enterprises and dealers of the capital chain.

500 million led lighting market scale needed R & D support

But we should also see that we have a big gap compared with enterprise innovation ability and multinational companies, most of the nearly 5000 LED lighting companies in China is still stuck at the level of small workshops and small factories, and the quality of product is uneven. New listing the six packaging applications enterprise R & D team for less than 200 multinational R & D personnel in more than 2,000 people.

500 million led lighting market scale needed R & D support

Another lack of R & D investment and scattered upstream lack of core patents, more than 80 units of the “Eleventh Five-Year” period 103 topics to split 3.5 billion 863 plan research funding, while the multinationals annual R & D investment of 300 million. The rapid development of semiconductor lighting technology, product life cycles are very short, if a little slack on the technical innovation and product development, it will cause a widening gap with the international advanced level.

In response to these issues, the National Development and Reform Commission, Central Information Secretary, Deputy Director Xie pole made important instructions from a long-term development perspective: To clear positioning itself, the formation of a common technology platform, industry standard guide, three promote technology innovation and industrialization. In standards development, China has formulated and announced 12 GB and 10 line standard, National Semiconductor Lighting Project R & D and Industry Alliance, the CSA led the development of the test methods and technical specifications of the 10 applications.

China in the field of general lighting LED lighting market has been more applications, such as tunnel lighting, road lighting, airfield lighting and underground lighting, etc., also emerged in the application of a number of demonstration projects, such as the Great Hall of the semiconductor lighting energy saving project, the Potala Palace in Tibet semiconductor lighting energy-saving projects, the Water Cube and the Shanghai World Expo Pavilion LED lighting. But the general LED lighting market share is still small, the application is still in the early exploratory stage, large-scale promotion there is a long way to go, especially the need to solve the following problems:

(A) LED lights price is still high, although state financial subsidies, it’s difficult to achieve an acceptable level of most of the projects and the ordinary people. This requires technically further innovation and development, reduce costs, and develop a large-scale industrialization can low price products.

(B) the current semiconductor lighting product testing methods and standards development is lagging behind, far behind the technology and product replacement rate. This leads to the uneven quality of the products on the market, it difficult for users to identify the product is good or bad, the defective circulation market share is still relatively large, people have a poor understanding of LED lighting products.

(C) industrial resources are not centralized, the market is chaotic, disorderly, cheap malicious competition is widespread, affecting the long-term and orderly development of the whole industry.

(4) Social awareness is not part of the field of energy saving, energy-saving effect of cognitive semiconductor LED lighting market is not yet in place.

Domestic led industry grows well

China attaches great importance to the semiconductor lighting technology innovation and industrial development, and has introduced a series of related policies and plans. The semiconductor lighting in China’s seven strategic emerging industry is an important development. Ministry of national science and technology have plans in 973 and in 863, which will research and development support.

Domestic led industry grows well

In 2009, the national development and Reform Commission and other 6 ministries jointly issued the ” semiconductor lighting development views “, The national development, Reform Commission, housing construction department and Department of transportation carried out joint application demonstration project of semiconductor lighting products in 2010. The state issued incandescent light route map in 2011. The State Council issued in August of this year ” energy-saving and emission reduction ” Twelfth Five-Year Plan ” ” point out the positive development of semiconductor lighting industry and accelerate the key equipments for semiconductor lighting, core material and the key common technology research and development. The Vice Premier Li Keqiang had a chance to make inspection for the led industry and china led flood lights in June 18, 2012.

At present, China’s semiconductor lighting industry has formed a relatively large industrial scale and a complete industrial chain which also has good industry foundation. Especially in recent years, China’s semiconductor lighting industry development grew very rapidly along with the international industry transfer to China,the domestic industry investment growth and the level of industrial technology of the rapid promotion. It already became the world fastest area, and preliminary already built relatively complete industrial chain.
According to the national semiconductor lighting project development and Industry Alliance ( CSA ) statistics, China’s semiconductor lighting industrial dimensions already achieved 156000000000 RMB in in 2011, which includes upstream epitaxial chip production value 650 billion, 2850 billion in output value and the middle package downstream application value of 1210 billion.
” Eleven five” period, China’s semiconductor lighting industry average annual growth rate reached nearly 35%, which is expected to make” 12th Five-Year Plan”, the industry average growth rate will exceed 30%, in 2015 the industry overall dimensions will achieve 5000 billion RMB in 2015.
Under the national policy support and market demand drive below, our country is preliminary already formed from upstream epitaxial material. The semiconductor lighting technology has been rapidly promoted, the key technology and international has to been narrow. led industry chip localization rate has reached 68% in 2011, and the industrialization of high power LED light efficiency reaches 120 lm/W. with independent intellectual property rights of the Si silicon power, LED optical efficiency become more than 100 lm/W; so does the UV semiconductor lighting R & D.

4, To promote their products should according to the technical requirements of the market environment

Whether product performance can achieve environmental requirements or not, which is the most critical. In the design, marketing, we should consider the advantages of world of led package  promotion and to promote their products according to the technical requirements of each market environment. If just for promotion and marketing, they will often have a negative impact after they run out of the lights, and realize it is not good as what you said, when they put something, after one or two years, it go die. At that time, he was taken for world of led attitude absolute boycott, the most typical example in this regard is the street light.

5, there is a need to study the market segments

Lighting enterprise scale, what would like to do much less likely to? This can be seen from the traditional lighting companies. Because the biggest problem of lighting products is to involve the design, it is not your standard products that will be able to sell a building as long as involved in the design, the size of the business you do not go, do not like home appliances. So do LED lighting, in particular, they need to study the market segments, For example, the emergence of this world of led, it gained a good application on the filed of travel, military, aerospace, airport every aspect of market segments in fact make it easier for you in this field to become the boss, do not necessarily have been a cook billion scale enterprises.

6, what kind of products are sold to what kind of market

If you want to have your Lamps to do well, the quality is very critical. Of course, price is one aspect. Try to do, can market is divided the lighting companies into two categories? one is the high-end market for high quality requirements, lighting can be done with the first-class brand chip, the product can be sold more expensive; the other is for the low-end market, it can be appropriate to reduce costs. Such sales, to let customers understand your product in the end belonging to which level, what kind of application environment. To a certain extent, it can be avoided the product prices disorderly competition.

Market cultivation expansive approach for world of led (1)

For the uncertain market, the really need, perhaps, is the concept of a more rational and constructive thinking. The Union Assembly, representatives of the participating companies have raised a number of insights, such as “to promote the right product in accordance with the technical requirements of the market environment”, ” and actively cultivate and open the domestic market”, “cost control spared article” “deep secret agents in the emerging market and market segments” “Focus on the added value into the world of led pn junction system to provide customers with solutions. Of course, the reason should not just talk about it, how to form a high degree of consensus in the development of the industry and transform into the real engine of the action force, which are the market forward.

Market cultivation expansive approach for world of led 1

Actively boost domestic market

The domestic market is very large indeed, how to pull the domestic market? In this regard, the government has had a lot of practices, but need to do more to cultivate the market, and they should actively encourage more people, more businesses, institutions, and more families to understand the world of led, and to propaganda better of the LED’s advantages and social benefits with actively boost domestic market.

2, to avoid the “low-price competition”

In the past two years, why the market price has continued to drop? In addition to the supply and demand of the reasons of the above, as well as one of the main reasons is because a lot of small businesses simply do not know the technology, which is simply a layman to run world of led lighting, but in order to stay in business, and grab orders, so they put the price be low; This actually a sad to our industry.

3, how to reduce costs?

Judging from the current situation, the domestic chip companies this year, or a considerable number of enterprises will encounter shuffle, the first half of next year there will be more. The key for businesses can not survive or not is in quality and cost. Enterprises, especially the equally important role of the cost should be placed and technology, but how we can reduce the cost of it? Generally speaking, it is the scale, output, as well as lowering the price of raw materials and logistics costs.

The lifetime of LED components

Basically, LED is a kind of semiconductor component (diode) that can emit light, which is also a type of electrical component. Normally, the estimation of LED components should use accelerated life testing (ALT led street light pdf) method with a couple of mature samples and statistical analysis. The current LM-80 specification based experiments on three different testing temperatures, and together with the lumen maintenance regulated by the Energy Star. It is not really controversial to use it as the single standard to determine the lifetime of LED components. Especially after the launching of TM-21 life estimation solution, LED chip manufacturers no longer determine the service life of their products by themselves. But led heat dissipation problems still existed:

 

Basically, LED is a kind of semiconductor component (diode) that can emit light, which is also a type of electrical component.

 

  1. In the LM-80 specification, LED chips should be tested in three different working temperatures. In each temperature, at least 85% LED chip should pass the 6000-hour aging test, and using the lumen maintenance parameter as the only basis for judging. The problem is this is a statistic process. Within the 6000-hour test, there are still 15% LED chips cannot pass these tests. The failure of every single LED chip will cause the failure of the lamp, thus for LED application manufacturers, lumen maintenance based on the LM-80 specification is unreliable.
  2. In order to increase the accuracy of LM-80 in estimating the lifetime of LED components, clear definition of failure modes are necessary, for example: lumen maintenance rate, dead lights, burned components, color coordinate/voltage/current offset. The occurrence of any one of these faults means the death of the lamp. In addition to grain quality, including the selection of packaging materials and packaging technologies will impact the lifetime and reliability of LED elements. Therefore, LED elements insisted on LM-80 tests need to pass the tests for reliability qualification, which is necessary.
  3. In order to reduce the interruption risk during LE-80/6000 hours tests caused by the failure of LED components, usually LED manufacturers may increase the number of testing samples. According to the regulation of Energy Star, dead lights will not be included into the calculation of average lumen maintenance rate, but should be marked within the final LM-80 report. Thus, when LED application makers read about these LM-80 reports, they will learn about the failure rate as well as the average lumen maintenance rate.

Does the lumen maintenance data can represent the service life of LED lamps?

There are two main problems in current LED lighting market:

 

The first one: unclear identity. According to the test of ITRI industry, more than 50% LED bulbs in the market are insufficient in output luminous flux as they have been marked. It is estimated that measured results will be 10% less than the value given out by laboratory experiments.

 

Does the lumen maintenance data can represent the service life of LED lamps?

 

The second problem is the different quality. Currently, there is no unified standard to provide clear definitions to the relationship between prices and qualities. In most of cases, customers might spend a lot of money but did not obtain the corresponding high-quality products. This situation made buyers from other regions, like Europe and the United States paid more attention on the identity and quality of LED lamps/bulbs.

 

Does the lumen maintenance data can represent the service life of LED lamps? At present, the most official representative standard related to the service life of LED bulbs in the LED lighting market should be the LM-80 specification released by the Energy Star (U.S. Environmental Protection Agency) for LED Lamps. However, a number of different voices now have been found in North America. Some experts call on the abolishing of LM-80 specification immediately since it is not accurate as people expected in estimating the service life of LED bulbs. At least, it should not be the only specification for that.

 

In fact, in 2006, the U.S. Department of Energy Quality Working Group for Solid State Lighting (SSL) invited 32 LED experts and conducted a series of deep discussions about the reliability and lifetime estimation methods for LED lighting products. In consideration of the LED technologies at that moment, it is proved that lumen maintenance (L70) will be the most representative and most reliable specification for determining the life time of LED lamps. The light attenuation of LED lights is step by step process, which is too slow to be sensed by human. In the early stage of light attenuation, people can hardly recognize their lamps become dimmer. Not until the light attenuate to only 70% of the initial light intensity, the lost brightness of LED lights can be noticed. Thus the working group of U.S. Department of Energy Quality Working Group for Solid State Lighting suggested that L70 should be the only standard of LM-80 specification in determining the lifetime of LED lights, including LED bulbs.

Applications of high-frequency non-electrode LED lamps

High-frequency non-electrode LED lamps – a new green light source with high energy efficiency in the 21st century. The general working principles of this lamp is coupling energy into the bulb through the high-frequency induction magnetic field energy; forming plasma within the bulb via avalanche ionization; when excited atoms return to the ground state, they will send out UV rays (254nm), which is also called spontaneous emission; the fluorescent powder stimulated by UV rays, they will send out invisible light. Lacking of electrode and filament makes non-electrode LED lamps immune to the lifetime restrictions caused by light sources. The average service life of high-frequency non-electrode LED lamps is more than 60,000 hours, with a power factor higher than 98%, instant start and re-start, the efficiency of the entire system is no less than 63lm/W, color temperature between 2700K to 6500K, with CRI larger than 80, normal working temperature of -25℃-50℃. High-frequency non-electrode LED lamps have really good performances in many optical parameters. Their high efficiency and lower power consumption can save more than 60% energy compared with other traditional lamps.

 

Applications of high-frequency non-electrode LED lamps

 

Because of using solid amalgam, these lamps will not cause damages to the environment. 99% can be recycled, no flicker, low heat generation, led advantage no light pollution, long service life, no maintenance and frequent replacement, which saves a lot of human and material resources. High-frequency non-electrode LED lamps are widely used in factories, shopping malls, offices, classrooms, streets, parking lots, gas stations, stadium management, bridges, etc., especially used as green light sources in tunnels, subways, billboards, cold storage and other places where maintenance works are rather difficult.

 

Non-electrode lamp is not a new invention. As early as 100 years ago, American scientists invented similar lighting technology. However, due to all kinds of restrictions in technologies at that moment, non-electrode lamp can only stayed in the laboratory for a long time. Recently, scientists felt interested in them again and tried to combine this technology with LED lighting source (the 4th generation light source).

 

According to statistics, 20% of energy consuming of our country is from the lighting industry. If 1/3 of our current light sources replaced by LED lighting applications, then more than 150 billion degrees electricity will be saved every year. Estimated in accordance with the existing power energy structure, this assumption will reduce the carbon dioxide emission by 25 million to 43.2 million tons.

Future development of LED down lamps

With the development of LED down lighting technology, a large number of LED manufacturers realized the importance of product quality. Only high quality LED lighting products can impress customers and make them decide to replace their old traditional lighting applications with LED lamps.

 

With the development of LED down lighting technology, a large number of LED manufacturers realized the importance of product quality.

 

It is the quality that determines the future direction of LED down lamps. In fact, LED lighting industry is suffering bottleneck currently. The over-expensive production cost made them be hardly accepted by ordinal buyers. Compared with traditional fluorescent lights, which is only cost several USD, LED down lamps are incomparable. Experts believed that in order to successfully break this bottleneck, LED manufacturers should improve the quality of LED products, prolong the service life to more than 50,000 hours. In addition, they also need to spend more energy and time on the appearance design.

 

Thank to their own advantages, designers will have more creative space if they choose to use LED lighting products instead of traditional lamps. That is the main reason that more and more interior designers would like to use LED down lamps, which break the traditional concepts of appearance. The energy-saving and low heat dissipation features make LED down lights also can be used in the commercial and industrial areas.

 

With the increasingly popularization of LED lighting technologies, a large number of inferior LED down lamps flooded into the market, the instable quality of them broke the expectations of buyers towards LED down lights, even exerted bad influences on other LED lighting products. Because of the lacking of a unified standard in the LED lighting industry, consumers usually felt helpless when they bought some low-quality products but found nowhere to complain. All these casted a thick layer of shadow on the future of the lighting industry. The majority of small and media sized LED makers either to sink in the pessimistic ocean or to struggle to survive under the huge pressure. The time will give out the final result.

 

What LED makers needed desperately right now is a unified standard. They should not pursuit the immediate petty profits at the cost of the overall development of the LED down lighting products. LED down lights have a bright future, but LED manufacturers have to aim high and learn from mistakes that they made before.
