Energy saving lamp style single high prices to be improved in rural popularization
I visited the the Nanping major urban lighting shop found popular in the rural energy-saving lamps, by the impact of a single style, high prices and other factors, the penetration rate to be improved.
Bayi a lamp shop owner Mei said they shop selling lamps are mostly energy-saving lamps, monthly sales of more than 500 lights. The person in charge of more than lighting shop said that if the subsidy policy of "backing" energy-saving lamp market will be more prosperous.
Mr. Lin, who lives in Plum Village, the impression of energy-saving lamps. Last year, energy-saving lamps nearby sales in the District government subsidies, he breath hold two boxes of home. The Ziyun community Oon but then energy-saving lamps uninterested in the shape of this lamp is not fashion, I only installed in the bathroom. "While public Yang does not like the energy-saving lamps is due to its price ratio normal light to a lot more expensive, not to mention the poor quality of some light, does not take long to burn, not enough affordable to use. Just really easy to use energy-saving lamps, different people saying the same.
Beijing this year advocate green lighting promotion of 12 million energy efficient light
This year, Beijing will promote the 12 million efficient lighting products, to the end of the green lighting of all public service organizations and households. Recently, this reporter learned from the Beijing Municipal Development and Reform Commission, public service organizations are required to recover the replacement of energy efficient lighting products, to be replaced more than 90% of waste light. Recycling of waste light by the enterprise to unify Beijing hazardous waste disposal center, funded by the Government harmless treatment.
2004 from Beijing to the implementation of green lighting project, within the next three years to promote the 1.8 million efficient lighting products. The replacement of a large number of energy efficient lighting products, followed by the disposal of waste light to become a prominent problem. According to the understanding, fluorescent lamps and other lighting product contained mercury, lead and arsenic and other elements are polluting the environment, harm to human health of hazardous substances. An ordinary T8 straight tube fluorescent lamps, mercury levels were usually 5 mg to 10 mg.
Began in 2007, Beijing s green lighting project to increase a content: recycling of used light source. Recycling of waste light by the enterprise to unify Beijing hazardous waste disposal center, funded by the Government harmless treatment. Government each waste light sound processing fee subsidies.
2007 and 2008, Beijing for the disposal of waste light subsidies to 160 million. "The person in charge of the Beijing Development and Reform Commission, the Environmental and Resources Department, said the 2009 recovery figure is verification, the amount of subsidy is not yet finalized. With the number of recycling increases, the subsidies will certainly be increased accordingly.
New energy-saving lamps, government subsidies for low-cost, positive people to purchase; waste light source, the government pays for disposal, recycling is not overwhelming. Although each community has established to receive the scene in the "energy-saving lamps waste light recycling bins, can recovery rate of less than one percent. "Some families of used light source can be replaced to keep the future, do not want to be recycled." The relevant person in charge of energy saving and environmental protection to reporters said.
Low compared to the will of the residents recycling, waste light recovery of public services is usually about 70%. "We hope that in addition to normal wear and tear, can be recycled at least 90% of replacement of used light source." Municipal Development and Reform Commission official said. Light waste recycling is a complex project experience from abroad, on the one hand, need to establish a collection network, through subsidies to encourage people to replace; the other hand, through the development of laws and regulations, waste light thrown away, polluting behavior to punish.
out of incandescent LED can illuminate future?
In early November, the National Development and Reform Commission issued the "China to phase out incandescent road map" to the market known as the LED lighting revolution into a cardiac stimulant. Sharp decline in the face of the backlight market, the industrial development of chaos, LED general lighting industry can become the "savior"?
Grim reality of a better future
In this year s ELEXCON on, LED is undoubtedly one of the hotspots. "High-end LED lighting market less affected by the economic downturn, high-end market segment in the pursuit of quality lighting giant more, so they will invest in the use of high-end materials products, and those low-end packaging market in the enterprise, by more pronounced economic downturn affecting the future, the company s strategic focus is one of the LED market. "Yi Technologies AG, a large vice president Chen Zhengming in the exhibition" China Electronics News "reporter, showing confidence in the market for LED lighting . The world s second largest manufacturer of SMD thick film chip resistors, LED mass production this year by the official blew the ceramic package substrate to enter the LED market, the high-end horn. China Electronics (CEC) Solomon Systech s director of business operations areas Wei Jiang also held the same view, he believes the current LED lighting business closures just downstream market shuffling process, that are not core competencies of the low-end manufacturing business will certainly be eliminated, and in the high-power LED lighting driver IC hard Systech is optimistic about the company s future growth.
"LED is facing great potential prospects, but there have been some impact on the healthy development of the difficult issues." By the China Electronic Information Industry Net, China Electronic Appliance Corporation co-sponsored the 2011 China (Shanghai) LED industry healthy development of the Forum, Xiamen Hualian Electronics Co., Ltd. Fan Yu bowl laments.
LED luminous efficiency of 150lm / w (lm / W), LED lamp luminous efficiency 120lm / w, accounting for 30% of the lighting market, the annual saving 100 billion kwh, reduce carbon emissions 98.99 million tons; in 2020 accounted for 50% of the lighting LED lamps market, the annual saving 340 billion kwh, equivalent to four Three Gorges Hydropower Station. However, the reality is not so ideal. Fan Yu bowl, said that China s industrial power LED light effect in the 100 ~ 110lm / w level, LED lamps lighting effect in the whole 80 ~ 85lm / w between; LED lighting and traditional lighting price gap is also larger, the cost of a LED lighting to promote the stumbling block; In addition, the first half of 2011 China s LED bulbs output more than 60 million, more than 76% of global production in China of LED bulbs, LED bulbs export-oriented, the proportion of exports accounted for more than 82%, 60 million in Only 6 million in domestic use, from 30% of the lighting market share, there are many way to go.
It is worth emphasizing that, despite experiencing a high brightness LED s start with the start-up stage to the "Eleventh Five" China s LED industry has begun to take shape, and entered a period of rapid development, but in the lucrative industry chain areas, China is still in short board. Leaving aside the lack of critical equipment at home, even if a foreign company to purchase key equipment, but in the upstream production techniques still have a long way to go. "Judging from the current level of technology and the overall industry trends, our country is still in the epitaxial chip technology early stage of development, the product is still middle and low, so the material improvement, photoelectric conversion efficiency, cost control and production and technological progress will continue in the future faced with opportunities and challenges. "China Electric Division No. 13, said Professor Zhang Wansheng.
Overcapacity issue
LED industry this year on over-investment, excess capacity, endless debate, and is known as the city of Shenzhen, China LED of an LED manufacturers appear more closures of excess capacity is further enlarged the debate. However, the reporter saw that, while an expert to talk about over-investment, excess capacity, while the company heavily smack to the LED industry, especially the upstream industry, the industry has become restless.
Since last year, backlighting and general lighting for the rapid development of projections were too optimistic, resulting in excessive investment in the upstream LED. Sapphire substrate most serious over-investment: manufacturers (including those under construction) of 41, a total of 44.7 billion yuan investment, production capacity of approximately 330 million / year, far greater than the actual demand; LED epitaxial silicon over-investment, followed by Currently there are 85 factories, 96 factories under construction, with a total investment of 183.5 billion yuan. MOCVD for the 4519 Master Plan sets the current practice with 543 units, January to July 2011 increased more than 200, 2012 China s LED chip production capacity of 10 times in 2010. Sapphire substrate from the beginning of $ 35 / piece to the current $ 13 – $ 15 / piece, an average reduction 50%; LED chip average price reduction of 25%, the maximum decrease of 42%.
However, falling prices and business investment is not pouring cold enthusiasm, this year described as "sapphire of the Year" in October of this year alone, sapphire substrates have two production industry and the investment astonishing: October 28, the energy giant GCL Sapphire project was formally put into operation, a $ 300 million. October 26, Elton optical one hundred kg level LED sapphire crystal project has officially started production, the goal is to produce 30 million LED sapphire substrate. The swimming season, general manager, said the total investment of 2.2 billion. In addition, LED industry, the other three optical giant will invest 25 billion yuan in Fujian Quanzhou (Lake head) optical sapphire substrate Industrial Park to build a factory, and strive to 2 years to complete. Amethyst 29-billion in proposed optical Xinjiang Production and sapphire crystals.
Excess capacity for investment risk, says that corporate executives do in fact have "a pretty good idea." Elton optical shareholders Guiyang Industrial Investment Group Chairman Xu Hao in the "China Electronics News" reporter, says that although the European debt crisis and rising domestic prices, higher labor costs, RMB appreciation to the many industries had a negative impact, but the next 2 to 3 years or LED lighting will be rapid development, especially high-end lighting market, companies are now on stream just for the next 2 to 3 years to prepare to seize market opportunities rising demand . In addition, providers GTAT Sapphire Dan Changjing furnace Sapphire vice president, general manager of business equipment and raw materials CherylDiuguid that the decline in prices can only show a small size substrate chip oversupply, large size of the substrate film is still highly profitable, prices are also higher. For example, the current four inches sapphire films offer about $ 50. And domestic investment in these sapphires were the main goal is focused on four-inch and above large-size substrate.
Rational development of the flow
Maturity of technology, decided to expand the market situation, regardless of whether the investment is the excess heat capacity, the industry should be a rational treatment of the development of LED industry, companies must also follow market opportunities and actively push forward step by step. Fan Yu said bowl for the short and long term planning, business investment must not blindly follow the trend, not a single pursuit of land and other benefits, go astray, causing investment risks, seize the moment and lay the foundation for the future, prevent risks before steadily line, is the better choice.
In addition, government policy, industry experts have said that the country should invest in health of the macro-guidance, the national research organizations, industry-specific evaluation, the actual work done fine form at the national level response and landing; guide get rid of the existing "designated Xinjiang autonomy", does not consider global investment patterns tend to be the whole country, focus and guide the development.
Government should have the courage to face those that have occurred can not circumvent the problem, after a round of investment, it should be a rational analysis and evaluation of the investigation, focused. For in fact do not have the technology, human resources are not available, management does not have, and only land plants, only the money of the company, to research, based on the guide adjustment, integration gives way to avoid waste of resources. For low-level redundant construction, should also be based on the research, strengthen macro guidance of state government and industry, or merger, or dismount, or determined to improve their level of access to high quality state of development. For resources companies should focus on fostering the development, the formation of the national backbone, the backbone of the industry, support forward, really have to build China s own international competitiveness "carrier group" to seize the opportunity to meet the challenge.
GE introduced two Energy Smart LED lights for general lighting
Recently, GE Consumer & Industrial s new two LED lights, a is the 7W s Energy Smart PAR20 led lights, the other is a 10W Energy Smart PAR30 LED lamps for general lighting applications. GE developed these products using the latest "ecomagination (ecomaginationSM)" concept and technology, the concept is characterized by the use of advanced optical control system, the LED emitting a white light focused on the target area, and can effectively reduce the external free light source.
Standard with 45W R30 incandescent lamp (luminous flux 485lm) or 50W PAR30 halogen lamp (luminous flux 630lm) compared to the company s new 10W Energy Smart PAR30 LED lamp is just the uniform, and color and halogen light as clear, significant color rendering index (CRI) of 82, the luminous flux up to 340lm, energy savings of up to 80%, so it is an ideal substitute. The product of more than 20,000 hours rated life, the life of a standard incandescent or halogen 10 times. Use this new 10W LED lamps also reduce maintenance costs, annual energy cost savings up to $ 15 (compared with 45W R30 incandescent lamp, assuming annual working time is 4500 hours @ $ 0.10/kWh).
In addition, 7W Energy Smart PAR20 LED lamp (luminous flux 200lm) also has energy saving features. With standard 30W R20 incandescent reflector lamps (luminous flux 200lm) compared to 77% of the lamps can reduce energy savings. The product of the rated life of more than 20,000 hours, the initial light output of up to 70%. It features 82 color rendering index, color temperature 2700K and is divided into 3000K, so it s just a clear issue, and halogen light color and the same.
Two new LED lights are lead or mercury, and are RoHS testing standards.
