The average price of LED street light lens cut of more than 20%

 

The latest survey results show that the average price cut chip prices for domestic LED chip manufacturers since 2011 has exceeded 20%, international LED street light lens manufacturers, chip price cut of 10.8%, Japan, Europe and the United States chip price cut is only 5.18%, South Korea,Taiwan’s chip price cuts, with an average of 13% -16%. “Overcapacity, falling prices this is the inevitable result of the domestic LED investment boom. Ruifeng Electric chairman Gong Weibin, two LED backlighting and LED lighting market is the incentive for domestic LED investment boom. The explosive growth of LED TV, the market size of LED high bay lighting business will be increased by 5 times. The fact is, the 2011 LED TV penetration rate is over 40%, but as the technology matures, the absolute number of LED backlight chips are not doubling.

 

“The LED application products downstream inventory to the blind expansion of the cause of,” industry veteran Shi Weili pointed out that, in early 2011 and the years a lot of lighting export enterprises are think, overseas LED lighting exports will be substantial growth, while the blind expansion of production scale but to a firstthe fourth quarter, a large number of intent order was canceled, and safety requirements of the certification and domestic chip patent risk, Shenzhen LED lighting stock, originally for overseas exports should account for about 50%. Career, a middle-level leaders pointed out that the end of 2010, domestic LED street light lens industry is high, resulting in the domestic LED application market is expected to blindly into production of domestic LED chip manufacturers, but most of the products produced by small and medium-power LED chips, leading to domestic small and medium power LED chip production has a serious surplus.

Short-term development of LED solar street lighting system at an alarming rate

 

Short-term development of LED solar street lighting system at an alarming rate

 

The fact of the domestic market in 2011 was the production of small and medium-power LED chips can do less than 50% of the lamps, LED solar street lighting system really sell to the hands of users, but also less than 50% of 2011 domestic LED chip sales may also up to 50% less than the beginning of the year is expected. “In addition, the Samsung LED backlit TV is expected in early 2011 is too high, the formation of the inventory of a large number of LED chips, LED-backlit Samsung this part of the stock transfer to the dumping of domestic lighting market, change like exacerbated the LED chip to the plight of excess capacity. “LED business suddenly overcapacity has been very vigilant.”

 

Above middle pointed out that many early LED high bay light companies rushing to the next MOCVD orders, and now also suspended the order, part of the arrival of the MOCVD has also been idle at the plant early next year may also appear, will arrive shortly MOCVD equipment when used status of equipment for sale. “it is interesting, it is enveloped in a bubble burst crisis in the domestic LED industry, the incandescent phase-out map and may be released in early 2012 80 million LED lighting subsidies, letting the LED solar street lighting system industry to generate new market expectations, 3 An optical Ruifeng power, the country star power LED listed companies stock price limit on November 4. However, in accordance with the incandescent phase-out plan for the transition period from now to 2012, to October 2012 First incandescent lamp of 100 watts and more into disuse, two years after the phase out incandescent 60-watt and above.

Recourse integrations of LED outside lighting must be realized

 

Recourse integrations of LED outside lighting must be realized

 

The current pace of development of the domestic LED industry in the world, the number of firms in a few years to more than 4,000. However, due to the late start of the domestic LED industry, grasp core technology unsatisfactory; local achievements impulse, overheated investment, domestic LED enterprises but not big but not strong, costs are low, small-scale distribution concentrated difficult to form the development force, competitiveness is quite low. China is the most potential LED market presence, such as Cree, Osram and other large enterprises, the competition in the domestic LED outside lighting industry will gradually upgrade into an international competition, if the domestic LED industry development model, the future of China’s LED market will be the dominance of foreign companies. Therefore, the LED domestic enterprises must take Baotuan development, resource sharing, win-win cooperation, both to avoid disorderly competition in the interbank, the better to create a powerful force for development. Baotuan development trend of the Association for the Promotion intends to set up relevant institutions, the actual situation of domestic LED high bay lighting industry development and the introduction of the corresponding guide policy in a timely manner, to work together to deploy the industry’s resources, including capital, technology, human resources, domestic LED industry seeks to promote the healthy and orderly to move forward. The experts concluded that the delay in the home lighting market open, backlight sharp drop in demand, shrinking market demand in Europe and America in the context of the entire LED outside lighting industry resources to a reasonable integration of the price war aside, put aside the disorderly competition, aside product homogeneity, and take the road of healthy development.

LED indoor lighting is expected to be the protagonist of the architectural lighting market

 

LED indoor lighting is expected to be the protagonist of the architectural lighting market

 

It is estimated that the output value of the 2012 LED used in architectural lighting than doubled last year to grow to $ 684 million. Since the Expo, the endless discussion about LED lighting, is undeniable, the LED indoor lighting lamps are expected to fully replace the neon and then to become the protagonist of the architectural lighting market.

 

LED indoor lighting market to develop the next generation of lighting as a national strategic technology, the development of a new generation of IT will be important, but the LED lighting market in China dusk heavy, when the clouds are cleared to see the sky to be explored. Most Chinese enterprises to walk in the midstream and downstream industry chain upstream industrial chain and only a small part of Chinese enterprises, and the survival of extremely difficult technical problem is the primary obstacle to impede Chinese companies an attractive piece of cake eating.

 

Under the state’s policy orientation, local governments have been master of the LED indoor lighting industry, Dongfeng, the local economic structure adjustment and industrial upgrading, setting off a place to get the building wave of large LED production base. The low threshold of downstream technology, the natural into the LED industry, the most appropriate incision, the inevitable result of such large-scale investment in upstream and downstream industry chain is redundant construction and waste of resources, and even generate excess capacity and foam.

 

According to market research data show that Investment Advisor in the current state-approved six semiconductor lighting industrial base, in fact, most provinces have in-built LED high bay industry base, and intend to apply for a national title in a timely manner. The data show that only the first half of 2009, investment in China’s LED production has more than 20 billion yuan, while its tendency to expand continues.

Industry concentration is insufficient in LED ribbon lighting

 

Industry concentration is insufficient in LED ribbon lighting

 

This situation will naturally such as According to statistics, Taiwan-funded LED ribbon lighting companies in the Guangdong region alone, more than 500. Accumulation of a large number of enterprises caused by the downstream industry chain industry concentration is not high, in fact, the profits of the downstream industry chain is rather limited, accounting for only 10% to 20% of the whole industrial chain, therefore, the phenomenon is particularly prominent enough to go round, the level of competition One can imagine such a situation will inevitably lead to a chaotic situation such as disorderly LED ribbon lighting market competition.

 

Plate construction of China’s lighting industry is more and more obvious, in addition to national strategic factors driving the local government contributed to the loss of this stage, most companies or industry will promote re-integration and reshuffle, corporate investors, which both a challenge and an opportunity, To Win, to seize the industry high ground, with the industry to adjust timing to create a brand may be a rare opportunity

 

The vicious competition will inevitably reduce the ability of LED high bay lighting market Absorptive capacity, there may even destroy market confidence in the newly established enterprise qualifications of different products varies greatly, seriously hurt the consumers’ trust, the development of a new industry dangerous lack of market recognition of existing industry will remain flat, but become a drag on the market, the situation is not optimistic, which is the major factor in the current market volume of products sold to no improvement.

GE Lighting’s LED intelligent street lighting system

 

GE Lighting's LED intelligent street lighting system

 

Wang Jia Nuyi bridge recently, GE Lighting in New Zealand with several sets of new LED street lighting has a long history of local updates of traditional lighting systems. Wang Jia Nuyi River is the third largest river in New Zealand has a special significance in Maori culture, and Wang Jia Nuyi Bridge is the only one of several road and bridge rivers.

 

In order to improve the lighting conditions in Wang Jia Nuyi bridge main road, the City Council began to try to replace the traditional lighting technology, with different LED light source aimed at the application of energy-saving program. The new road lighting solution must maintain the same brightness as with conventional light sources have to meet the requirements of energy efficiency savings. Local lighting design company in New Zealand EvolveNZ GE Lighting of the 80WR150LED products.

 

EvolveNZ company general manager John Birks said: “The lighting configuration to restore the natural light to bring a more secure feeling and a white  light makes the space more modern and a sense of vitality in the night, can more clearly see the real life environment. we hope that this lighting technology to attract more people to travel, to experience the night scenery of their host cities. ”

 

Wang Jia Nuyi City Council infrastructure and assets Chairman of the Committee Ray Stevens said: “The new alternative can bring many potential advantages and benefits to the public, no doubt, members of the public will notice the new LED intelligent street lighting to generate white light, rather than issued by the installation of sodium orange light. Wang Jia Nuyi City Council will be phased in LED light source instead of the traditional lighting products, until it is completely replaced. ”

 

Seek long-term development of LED household lighting under the disorderly competition

 

Seek long-term development of LED household lighting under the disorderly competition

 

 

Response to the “patent war”. 2010 there will be some of the important field of white LED patent expires, other words, LED industry in recent years into a frequent patent litigation battle. According to incomplete statistics, the global LED household lighting application 124,000, which the United States, 20000 China, 25000, 49000 Japan accounted for. The key is the 25000 LED patent in China, mostly concentrated in the middle and lower reaches of the whole industrial chain, mostly design, utility model patents, invention patent very little. All have some peripheral patent in the upstream industry chain, but the core patents master degree.

 

 

 

Balance productivity growth and market demand. According to incomplete statistics, in 2010 only listed company in the investment in the field of LED over 30 billion yuan, 20 billion yuan of three safety photoelectric BDO Runda 4 billion yuan. LED industry investment in 2010, about 37% to invest in the upstream chip areas, 52% to invest in downstream applications, signs of overcapacity initially appeared. 1 July 2011, China MOCVD equipment increased by more than 200 units, is expected in 2012, China LED household lighting chip production capacity is 10 times that of 2010. MOCVD equipment in China more than 500 units, count 96 projects under construction, the total number of over 1600. According to statistics, the sapphire substrate manufacturing enterprises 41, planning a total investment of 44.7 billion yuan, including the planning of projects under construction amounted to 12.08 billion yuan in the projects under construction production capacity of 101 million / year. However, due to the global economic situation is not optimistic, the LED high bay chip demand declining. How to expand the LED general lighting market, and how the government should support the market, how to cultivate, all we need to solve.


The development of solar powered LED street lights should have a long-term vision

 

The development of solar powered LED street lights should have a long-term vision

 

Focus on new technology development. Such as the solar powered LED street lights internal quantum efficiency enhancement, as well as changes in package structure and new phosphor / quantum dots, the transparent substrate, contact materials, reflective materials, the second optical / lighting reflector’s design, and development of high-performance drive power .

 

OLED challenges can not be ignored. Solar powered LED street lights and OLED have their own strengths, when the LED high bay lighting market, but also face the competition of “compatriots” OLED. OLED display technology has been relatively mature, and has entered the market, lighting technology is taken seriously, in the rapid development of. The commercial grade white OLED light efficiency reached 50lm / W general lighting lights more than two times the life expectancy has reached 100,000 hours. And laboratory research and development of white light emitting efficiency of 120lm / W, is close to the U.S. Department of Energy requirements for lighting materials 150lm / W. Of course, OLED flat light source is also facing some problems: poor antioxidant capacity of the OLED light-emitting materials, power, afraid of the water, you need to vacuum glass seal, so need LTPSTFT substrate, OLED applications in the field of large-size the cost will be high; the yield of large-size OLED panels are still not high, a substantial increase in the cost of OLED product line, but also makes the production can not improve quickly; light-emitting material properties, component life by the effects of restrictions of the short board; surface light source specifications and drive power standard is yet to be established.

 

Should mains LED lighting industry put all of their attention on a longer life

 

Should mains LED lighting industry put all of their attention on a longer life

 

LED lamps for its long life, and environmental protection advantages, become a popular trend of the moment lamps. Just how long the life of the LED lamps? Generally believed not fake LED life of 100,000 hours, LED made ​​of light would be to have a certain power, the greater the power and cooling requirements of the higher, if the heat is not good, LED life is affected. Then there is the drive power supply part, and so on with the life of the LED lights. In addition also affects the quality of life, so normal in the mains LED lighting industry, LED life value parameter should be 30000-50000 hours. In fact, such a life already meet most lighting needs, far beyond the energy saving lamps, LED lamps of the incandescent lamp life, whether you want the blind pursuit of longer life?

 

Incandescent lamp life of standard definitions for 1000 hours, but for a long time occupied a civilian home lighting market, the most important reason is that the price advantage. Mains LED lighting life have an advantage, but the price allows consumers prohibitive. I believe that LED lamps have a certain life span advantage, no need to go too much in pursuit of longer life, as necessary to the pursuit of too high light efficiency. Compared to the price of energy-saving lamps, LED high bay lamps prices at a disadvantage, the people at home lighting in order to gain market share, reduce costs, speed up the popularization and application is king.

 

How to improve the working life of LED street light bulbs

 

How to improve the working life of LED street light bulbs

 

Recent U.S. Energy Star is being drafted to discuss the standards of the LED street light bulbs, among the more controversial point is that life on the minimum requirements, the EPA may be consumer lamp life requirements down to a minimum of 10,000 hours from 25,000 hours, because 10,000 hours compared to three hours daily point count has more than nine years of life. The latest EPA’s standard is that you can nominal life, the minimum of 10,000 hours, of course, if the test results, you can also nominal 25,000 hours or more.

 

The use of 9 years is enough for general home applications, hotels, subway stations, such as places of lighting required for a long time, you can use long-life LED street light bulbs, which indicates that the EPA later no longer LED lamp life across the board, only the minimum life requirements, the lighting of different places you can demand for life lamps, reflecting differences in demand for domestic enterprises is really good, so that small businesses and large enterprises according to their own conditions, to reduce the cost of LED bulbs while different levels, but also to improve the quality of their products, accelerate product updates and promotion.

 

Deal with material shortages. High brightness LED high bay chips metal indium is based on. The earth’s crust in the content in rows in the 61th, strategic metals in the number two, the development and application of growing, not rich reserves of global growth, the price, the expected future will appear periodic shortages. If LED into the general illumination market, bring problem is abundant raw materials? At present, many foreign countries and institutions and enterprises have begun to explore new chip in material, our country should also pay attention to this problem, to deal with the possibility of future rising prices of raw materials, research and development of new LED material.
