Solar LED lighting: market might have been over-exploitation


Solar LED lighting: market might have been over-exploitation

 

The promotion of local government procurement of LED street lights from the pilot into a universal application, and often the order of a street light project on the ten thousand. “Recently, Shandong Liaoyuan emitting solar LED lighting Business Unit Sales Director Cai Xingmao LED inside local governments to do the LED street light pilot project, an order of only a few hundred light, as many, but one thousand.

 

“Prairie fire luminous order of the first two months of this year had three times the same period last year, and each order is on more than ten thousand,” said Cai Xingmao hot extent of the current market can be attributed to the promotion of energy conservation projects in local government.

 

Recently, the Ministry of Finance Joint Development and Reform Commission, Ministry of Science and Technology announced on semiconductor lighting products, financial subsidies in 2012 to promote the project “domestic public tender, products related to indoor lighting and road lighting. Following the LED high bay lighting financial subsidy policy was first introduced in 2011, released a new round of subsidies for the project tender.

 

However, a street light in Sichuan enterprise person in charge of the total but has its own view: “suspected of over-exploitation of domestic solar LED lighting market.” The maturity of the LED lights is not enough large-scale promotion, too quickly to promote not bring technology advances, irrational investment.

 

“Streetlights biggest problem is the current product is not yet ripe, and is not suitable for large-scale promotion of brightness, illumination, and other technical indicators and sustainability is not a complete validation.” Zhang said.

 

Related statistics, the domestic LED lights in 2006 was only 40 or so, but as of now, LED lights enterprises has reached more than 1,400.

A big move to push the development of LED road lamp

“In the past few years, LED lights every year, hundreds of thousands of the problem was discovered, thousands of patents in the application, which means that the maturity of the technology is not enough.” Zhang pointed out that the LED street lamp needs a stable development of three to five years, three to five years after forming technology and genre can do. Now suddenly such a big move to push the LED road lamp technology may not yet mature, the entire market space has been fully digested.

A big move to push the development of LED road lamp

Zhang said, too quickly to promote not bring advances in technology and irrational investment, product development and cost of the decline in space will be wasted. The market is a finite resource, can not achieve sustainability.

 

Local Government driven by performance, there will be in the short term to replace the street lights out of impulse. “North a street light business executives pointed out, LED road lamp developed to dominate one of the last bound to form the background of the State-owned enterprises, enterprises do not requires innovation, not by technology, do not rely on lower costs, but by to talk to local resources. ”

 

Street sales channels are divided into the EMC engineering direct marketing and foreign trade in three ways, the current investment exchange market, the wind began to become increasingly popular, and getting worse. “Zhang said, at this stage, the LED lights also no perfect technology roadmap for people to use a variety of technical schools have, which will cause a great waste of resources. The short term, the government market for investment, business investment for the market, LED high bay lighting market may become more confusing in the next two to three years.

Shenzhen LED interior lighting product standards

 

On the afternoon of March 21, jointly sponsored by the Metrology and Quality Inspection of Shenzhen City, Shenzhen LED interior lighting industry standard Alliance standard released Publicizing the General Assembly to be held in Shenzhen. Shenzhen Collection Industry Co., Ltd., Shenzhen Metrology and Quality Inspection, Shenzhen LED Industry Standards Alliance member of the technical staff to participate in the standard release meeting. Yesterday’s Shenzhen LED Industry standard release of the General Assembly, the reporter was informed that the release of the standard is to gather for Industrial Co., Ltd. gather for the company for many years cultivating the experience and understanding of the Japanese market, in particular, talked about the achievements in the field of LED applications.

 

It is understood that the release of the Indoor LED ball bulb and indoor LED tube light standards from Shenzhen first proposed the first time in China. Shenzhen Poly relevant responsible person said, the drafting and formulation of the unit as a standard, the standard release of the energy efficiency of indoor lighting, grading and color temperature, color rendering index, the test methods clearly defined aims for Industrial Co., Ltd. specification, the current is more chaotic domestic LED interior lighting market, enhance the market competitiveness of the Shenzhen LED high bay lighting products. In addition, the revised standard specifies a specific luminous flux maintenance rate amendment not less than 98% energy efficiency rating parameters than before to have a more substantial upgrade. Industry sources say that the biggest highlight of this revision is the industry’s first general-purpose simulation design software for lighting simulation and experimental results is the combination of as considerations LED interior lighting product performance means.

To make led street light projects take off,reliable drive power is the key

To make led street light projects take off,reliable drive power is the key

With the constantly increasing of the LED luminous efficiency and the cost reductions, LED lighting is increasingly becoming the perfect substitutes for filament lamp and fluorescent lamp. But due to the complicated LED lighting system, across optical, electrical and thermal fields will easily arouse the problems of dismatching the power lifespan and lacking of reliability while applying in large-scale productions. In short, the real bottleneck for LED lighting(Especially led street light projects, led high bay) is driving power. As LED driver needs to work together with LED chip and module coordination system, and also needs to consider the electro-optical structure of LED module, So the drive power demand for LED lighting applications is different. Overall, however, the requirements of drive power towards LED lighting is nothing more than high efficiency, high reliability and campatibility for reversed light and non-dimming applications. Among them, the so-called high reliability should include the long life of mathing LED illuminant, width of the power grid application, self-protection and wide temperature tolerace(-40 degrees to 65 degrees, even -55 degrees to 85 degrees) on working.

In particular, LED street lights are mainly used for outdoor environments, which need to withstand the harsh environment of wind and rain, thunder and lighting; In southern China, the outside temperature may be as high as 40 ℃ ~ 50℃; In the cold north, the outside temperature may be as low as -20 ℃ ~ -30 ℃. Therefore, the design and manufacturing technology for led street light projects should be more attention to quality problems. The failure of most street light lamp can be attributed to a power failure, So led street light projects are facing special design challenges.

December 29 by the recent detection of the semiconductor light emitting device (LED)applications Product Quality Supervision and Inspection Center, China LED fluorescenttube entire lighting efficiency of up to 154.7 lm / W Refresh the domestic release of aboutthree months ago, LED high bay fluorescent tube the whole lighting effectworld record.
It is understood that the, Hercynian Research Institute, Chinese Academy of Sciences,Fujian Province, IMC Optoelectronics Technology Co., Ltd three safety Optoelectronics Co., Ltd. and Sichuan Sony Lighting Co., Ltd. has formed a joint Innovation Alliance ofLED technology. best led light bulb, The level of the world’s leading LED fluorescent tube used MCOB package every Western Research Institute of the Chinese Academy of Sciences and the Fujian IMC Optoelectronic Technology Co., Ltd. proprietary patented technology, San’anOptoelectronics Co., Ltd. Preparation of high luminous efficiency chip, best led light bulb, Sichuan Sony light Source Co., Ltd. Preparation of highly efficient phosphor.

The first companies to talk about cooperation Qing Town, local businesses, department stores Fu Sheng, Kwong Chi-hung, said that compared to traditional lights, LED lights,one-time cost of inputs, therefore, in order to get each other’s trust, Kwong Chi-hungwithsix months free trial, to promote their minds and accept each other try holding, best led light bulb, six months after the stores all use LED energy-saving lamps.

The effect of word of mouth continue to appear later, Fu Sheng boss Kwong Chi-hung,the days and department stores in Shenzhen, Dongguan the SPAR part of the franchiseowner, Kwong Chi-hung, soon reached an agreement with these large-scale project.Subsequent time, one after another with Graceland steamed product, best led light bulb, Agile Property andother large enterprises to achieve cooperation.

“Overall, however, are monomers of the local stores or stores use LED lights, the bigchain stores are basically not to spend the LED lights.” Said Kwong Chi Hung, before the establishment of his company, Dongguan, Retail the industry began to use energy-savinglamp, but today, best led light bulb, three years later, the majority of retail stores in Dongguan still use the lamp a few years ago.

High intensity led circuit concept for the future office environment

High intensity led circuit concept for the future office environment

Modern office space, led high bay, natural lighting and artificial lighting is completely separate from the singularity of the building materials makes the construction of internal and external have clear boundaries, and isolation from the outside environment, and then after a long indoor work, high intensity led circuit, physical and mental seemed tired. In addition, the only way to adjust the external sunlight for indoor illumination only adjust the curtains cover the windows of the area, but not the other way.

“Adapt” concept design is aimed to design a future office. Suppose that in the near future R & D kind of building materials to meet the thermal insulation and waterproofing conditions,  high intensity led circuit, can develop an intelligent LED technology, parameterized operator of the computer to calculate the indoor different day The time required for different illumination, and expression of a variety of even endless in this material. Specifically, in too sunny, this material according to the settings of the computer program to partially obscures the sun, while the remaining part is based on transparent mode exists; in a cloudy day,  high intensity led circuit, this material can be maximize the increase in the transparent area of ​​the space like a glass box around together, so sitting in the indoor work time due to exposure to the outdoor natural environment in general and, more importantly, to achieve zero consumption in the lighting, because today can reach the LED through the absorption of light energy directly into light energy technology is still limited, when the lighting at night, by day absorbed into the energy is insufficient to meet the indoor lighting at night and must therefore be part of the electrical energy in order to ensure indoor of illumination,  high intensity led circuit, so this level can not reach zero consumption; sunny during the day.

Overcapacity caused by the crisis in the garden led lighting industry

Overcapacity caused by the crisis in the garden led lighting industry

This stage LED production capacity has been in the cyclical and structural excess state, which makes LED enterprises have been a polarization of the situation. To spend three to five years for a large number of SMEs in the middle and lower reaches of the industrytrough, garden led lighting, probably would have already run out of funds.

In contrast, the days of the industry leading enterprises better than many companiesalready on the market, there are sufficient funds to do support. The latest data show thatnine local industry of LED-based listed companies, has completed a joint-stock reform of the LED enterprises have hundreds of.

On the other hand, garden led lighting, support for large enterprises, there are local government financial subsidies and large orders. 3 An optical investment in Wuhu, for example, according tothe Investment Agreement, the Wuhu city government to give 3 An optical to the purchaseof 200 sets of MOCVD equipment subsidies, 3 An optical device subsidies amounting to525 million yuan in 2010. As investment conditions attached 3 An optical still in Wuhu forthe order of 600 million yuan of LED lights within three years from 2010 onwards, led high bay, each year the purchase of 200 million yuan.

The LED industry is not only faced with a pattern of shuffling, but also because of overcapacity and facing the crisis of falling profits. Data shows that, fromJanuary to August this year, the upstream sapphire substrate prices have dropped from$ 35 / piece to 13-15 U.S. dollars / piece, an average reduction of more than 50%; an average reduction of the LED chip and the middle reaches of packaging products were 25 and 23% of downstream lighting applications, an average reduction of 21%, garden led lighting, but thehighest part of the light string 75 percent drop. Compared with the 2010 a good year, this year’s market chilly.

Upstream and downstream enterprises to appreciate better the market is merciless.Shenzhen LED company owner has been unable to sit still, he admits: “This year we have from the TV backlight to lighting products. If the last two years can not be listed orcan not get investment, garden led lighting, will likely not survive.” This is just small and medium enterprises a microcosm. If the layout of the MOCVD continue to expand capacity to continue to expand, the killings began in earnest for SMEs.

Investment frenzy caused by overcapacity of dimmable led downlight

Investment frenzy caused by overcapacity of dimmable led downlight

Senior Engineer Industrial Research Institute figures show: from January to July this year,the MOCVD equipment increased more than 200 units, is expected to 2012 LED chip production capacity in China is 10 times that of 2010. China’s MOCVD equipment hasreached 543 units, the count in the construction of 96 projects, dimmable led downlight, the total number will reach1642 units.

The number of devices greatly increased, but the overcapacity risk a sign of the materialaspects of overcapacity more worrying. The domestic LED sapphire substrate, with an annual capacity has reached 6.85 million in construction projects there are 41 investment amounted to 12.08 billion yuan. If the expansion is completed, the annual production capacity will rise to 101 million. 2011 the global LED sapphire substrate requirements ofless than 50 million, dimmable led downlight, less than 10 million domestic production can be a serious excesstrend has been apparent.

Last year, the market for LED lighting the rapid development of overly optimistic, resulting in excessive investment in the upstream LED industry, also led the industrytalent shortage, as well as structural overcapacity. The global LED lighting marketperformance as expected in the first half of this year, midstream packaging enterprises are faced with the awkward the semi-annual report of the domestic listed companies. dimmable led downlight, 
LED industry, the upstream sapphire substrate production overcapacity is most serious,the middle reaches of the packaging industry, although the production of relative surplus,but because of the worst anti-risk ability, it is expected that there will be nearly 10% of the enterprises at the end to be eliminated, while the downstream LED application as awhole the best performance.

Overcapacity has become the soft underbelly of the LED industry. Two years ago around the introduction of competing LED investment planning and construction projects, has been far beyond the actual market demand, led high bay, while the capacity of blind expansion of thepassion is still burning.

Policy drastic lead to investment frenzy for buying high power led

Policy drastic lead to investment frenzy for buying high power led

With the state has adopted policies to promote the application development of LED lighting, LED lighting market size in 2015 is expected to nearly one hundred billion U.S. dollars. China currently incandescent over 1 billion, 1/6 of the lighting energy consumption and total electricity consumption, promulgated as the “phase out the incandescent route map”, buy high power led, a huge lighting opportunities, the brightest of capital at an unprecedented rate Follower of fashion.

According to the National Development and Reform Commission statistics show that China’s LED lighting chips, packages, applications, industrial chain ratio 1:9:22, including 70 upstream, buy high power led, midstream packaging companies more than 1,000, 3,000 enterprises downstream applications. Downstream of the LED lighting applications, is the capital gathered in the spread of the hottest investment hot very quickly, but more an extension to the industry chain downstream, the investment will become more and more crazy.

Midstream in the LED packaging industry, buy high power led, the world’s largest LED integration and packaging equipment supplier ASM Pacific 2010 report disclosed that, as of December 31, 2010, the annual turnover amounted to HK $ 9.515 billion in 2009 of HK $ 4.732 billion. performance jumped 101.1%, consolidated profit increased by 203.8% compared to 2009. Sales profit rate of up to 33.8%, net profit is 3 times that of 2009, but the order continued unabated, small orders for basic goods available, led high bay even if large customers have to pay the deposit only after eight months to a year The goods can be mentioned.

Who ASM Pacific foreign enterprises such as a large number of orders? Is the country like the mushrooming emerging LED industry clusters and industrial base. The scale of the industry ranked first in Guangdong Province, for example, Huizhou the Career BYD lighting a number of investment exceeding one billion yuan of projects have been launched; have been stationed in Germany Osram, Epistar in Taiwan, Lee Chau electronics listed companies; Konka, Skyworth, buy high power led, Han’s Laser is the way of mergers and acquisitions, to increase their investment into the LED industry; more Dongguan ground on the scale over a hundred million yuan in Dongguan Fu, Fenghua Hi-Tech LED backbone enterprises.

Guangdong has formed a total size of the super-LED industry with 50 billion yuan, which is enough to see the current investment in the LED “Mad King”. The 2010 output value of LED lighting industry in China exceeded 150 billion yuan, compared to 2008 more than doubled since 2011, buy high power led,  LED lighting industry is in trouble, exposing a series of problems of the industry.

Development of ceiling led lighting market need to overcome

Development of ceiling led lighting market need to overcome

The LED lamp is not sold very well because LED prices and energy-saving lamps, incandescent gap. For example, the 3W LED lamp priced at 20 yuan, 7W 90 yuan for 10yuan and energy-saving lamps, incandescent only one yuan. In the domestic field, LED lights, ceiling led lighting, basic “reputation market”.

National Development and Reform Commission has formally issued a document to put forward five years later, LED high bay China will basically out of incandescent “. According to industryestimates, the size of the market out of incandescent will be up to several hundred billion dollars, ceiling led lighting, is expected to quadruple as the best alternatives, LED lighting industry within five years.

LED business of street lamps, advertising lights, outdoor lighting, all belong to the orders for products, customers generally have a personalized needs. Even in the same city, twostreet lights in brightness, ceiling led lighting, chroma, shape is not the same.

So, how to break into this vast market of home lighting? We must first understand thatLED home lighting delay in the capture of one of the reasons is the problem of expensivelamp prices. LED expensive mainly due to higher chip cost, chip account for the cost ofLED lights at least 1/3. However, two years ago, 1W LED chip prices is about $ 3, but now has dropped to less than $ 1. LED prices are too high with the decline in chipprices, ceiling led lighting, is expected to be resolved within the next five years.

Reduce costs in order to account for market opportunities. Then, relying on what toreduce costs? Experts have pointed out, if it is their own R & D, I do need a great investment for small businesses can not afford. In order to reduce costs and make the products with high technological content, ceiling led lighting, you can choose to cooperate with research institutions.
