Within a half cycle of the input power waveform, this series of events may be repeated several times to form the visible LED blinks. To address this problem, a TRIAC dimming key requirement is very low input capacitance EMI filter, and this capacitance can be decoupled through the TRIAC and the winding impedance. According to the formula, the dimmer module capacitance decreases, then, will be able to increase the resistance of the resonant circuit to suppress the oscillation principle, to restore the desired circuit. LED itself, life is very long, PWM dimming, and will not damage the LED's life expectancy; even PWM dimming LED heat to help reduce, in fact, also help to extend the LED life expectancy. Of course, in the system design, the need for effective detection and control LED temperature, to ensure reliable operation of the LED, reflecting its long life and low maintenance cost advantages. The use of the potential problems of the TRIAC dimming control LED brightness The current TRIAC dimming is a popular way of dimming the market.
TRIAC dimmers originally designed for incandescent lamps, but also introduced, such as Semiconductor, a leading provider of TRIAC dimming LED driver, very suitable for TRIAC dimming LED lighting. However, this approach also has its limitations lie, such as increased circuit complexity, affect the power factor, dimming level is relatively limited problem. ON Semiconductor, as applied to green electronic products, the first high-performance, energy efficient, silicon solutions provider, recently launched for residential and commercial LED lighting applications, LED drivers NCL30000. This device uses a flyback architecture of the critical conduction mode (CrM) higher than 0.95 power factor, single-stage topology, it is also to save the DC - DC (DC-DC) converter section, simplifying the circuit.
This device even in low also offers high energy efficiency, compliance with various regulatory requirements and overall system optical efficiency requirements. In addition, this device is compatible with cutting-edge TRIAC dimmer and tail along the transistor dimmer, depending on the dimmer used, the LED light output can be adjusted to less than 2%, providing excellent dimming performance. Semiconductor heat pushing LED Driver Solution Semiconductor recently introduced several important energy-efficient GreenPoint? LED driver reference design, namely: 1) 3W to 5WLED drive reference design. This reference design uses the size and characteristics of for MR16LED alternative configuration, after a carefully constructed and tested, and used to drive high brightness LEDs. This reference design based on the buck - boost topology, the use of non-isolated constant current configuration of the Semiconductor, working in about 150 kilohertz (kHz) frequency of the NCP3065 switching regulator.
LED light power supply design, there are several design challenges: the life of the electrolytic capacitor, and LED does not match the LED lights flashing, a common cause of and solutions, PWM dimming the impact of the life of LED TRIAC dimming control LED The brightness of the potential problems. ON Semiconductor Applications Engineering Manager Zheng were the causes and solutions to address these issues discussed in the text.
April 10, the third new energy-saving technology seminar invited experts of the Semiconductor to expand the site to explore the design of the LED drive power, the seminar with the same period of the 75th China Electronics Fair in Shenzhen Convention and Exhibition Centre, 5 Peony organized. The life of the electrolytic capacitor and the LED strip does not match the LED lighting is an important factor to consider is the LED driver circuit and the working life of the LED lamp itself should be able to be compared. Although there are many factors that affect the reliability of the drive circuit, electrolytic capacitors have a critical influence on the overall reliability. In order to extend system life, the need for targeted analysis applications, capacitance, and select the appropriate electrolytic capacitors. In fact, the effective working life of the electrolytic capacitor to a large extent by the ambient temperature and ripple current on the internal impedance caused by the internal temperature rise.
The rated life of the electrolytic capacitor manufacturers of electrolytic capacitors is derived based on exposure to the maximum rated temperature environment and the imposition of the maximum rated ripple current conditions. The typical capacitance of 105 ° C rated life is 5,000 hours, the capacitor actually suffered stress compared to the nominal level, the lower the longer the effective working life. Therefore, on the one hand, the rated working long life and can withstand high rated operating temperature of the electrolytic capacitor is, of course, to extend the working life. On the other hand, according to the actual stress and operating temperature, can still choose to lower the capacitance of the rated operating temperature and rated life, thus providing a more cost-effective solutions; another point of view, considered in the design to maintain an appropriate stress and temperature can effectively extend the working life of the electrolytic capacitor, making it more and LED life to match. For example, the Semiconductor meet the "Energy Star" standard off-type solid-state LED bulb driver GreenPoint (TM)? Reference design selected Panasonic ECA-1EM102 aluminum electrolytic capacitors, rated at 1000? F, 25V, 850mA, 2,000 hours and 85 ° C.
Assume that 50 ° C ambient temperature conditions, the capacitance of the useful life of more than 120,000 hours. Therefore, try to make the LED driver circuit in the appropriate temperature conditions, and properly handle the heat dissipation problem, you can achieve the matching of LED driver circuit with LED working life. Overall, the LED strip driver circuit must be used electrolytic capacitor, it must strive to control the application of force and working temperature capacitance suffered to the greatest extent be extended capacitor working life of LED life match; the other hand, designers should be possible to avoid the use of electrolytic capacitors. Usually the human eye can perceive frequencies up to 70Hz light flashes above this frequency is not perceived.
Therefore, in the LED lighting applications, the pulse signal frequencies below 70Hz low-frequency component, the human eye will feel the flash. Of course, in the specific application, there are a variety of factors could cause the LED flashes. For example, in the off-low-power LED lighting applications, a common power supply topology is isolated flyback topology. 8W offline LED driver GreenPoint (TM) Semiconductor meet the standards of the ENERGY STAR Solid State Lighting? Reference design, for example, not to the primary bias due to the sine of the square wave power conversion flyback regulator provides a constant energy, dynamic Self-Supply (DSS) circuit may be activated and trigger a flashing light. To avoid this problem, we must make the primary bias in each half cycle part of the discharge Accordingly, choose to have this bias circuit capacitance and resistance value. In addition, even if it is to provide excellent power factor correction in the use of support TRIAC Dimmable LED Driver applications, also called electromagnetic interference (EMI) filter. Transient currents caused by the TRIAC step (step) will stimulate the natural resonance of the EMI filter inductors and capacitors. If the resonance characteristics of the input current to the TRIAC to maintain the current under the TRIAC will be closed. After a short delay, the TRIAC usually will turn-on, stimulate the same resonance.

In addition to the display wall (picture), as well as the large screen, emergency lighting, the exit lighting, billboards, decorative or architectural lighting.
Captions: the area of public meetings, board the high-gloss white high power LED.
Captions: high power LED in the neon industry is widely used - including the exit lighting, architectural signs, emergency lighting and billboards.
Captions: newly listed high-power LED technology not only energy efficiency and light quality.
Many countries and regions, many provinces, many cities by the regulations, or other means, abandon the traditional lighting in favor of use of new technologies, such asinduction lamp (light emitting diode) traffic, street and other public lighting. Such as the European Union countries, Japan, Australia, Brazil and Canada in 2012 would strictly prohibit the use of incandescent bulbs. Medical equipment, signage, consumer electronics, home appliances, decoration, security and other lighting equipment designer in the development of new products, the use of high power (1 watt or higher capacity) and an increasing number of LED technology.
The sensational LED light box What are the reasons so popular? Why LED Market Forecast in 2009 despite the economic challenges facing there are still significant growth? Answer two: today's high-power LEDs can not only improve efficiency, but also to provide better lighting effects.
High-power LEDs are extremely energy conservation, and higher brightness per watt than any other technology, LED bulb issued. Such as the ordinary high-power LED-per-watt can provide 80 lumens, energy-saving lamps (CFL) can provide 70 lumens per watt, an ordinary incandescent lamp provides 15 lumens per watt only.
Special high-power LED energy consumption in the 1W to 10W. 40W low-power household light bulbs and 60W incandescent energy consumption compared to its energy consumption is quite low. In some cases, the energy consumption of 60W incandescent equivalent to the power consumption of 15 watts energy saving lamps (CFL), energy-saving lamp power consumption is closer to the energy consumption of the LED panel light . However, another important win points in the high-power LED is not contain mercury. Energy-saving lamps contain a small amount of mercury, and is now the world, provinces, municipalities restrict the use of mercury-containing lamps. Typically, when the energy-saving lamps and LED to achieve the energy saving requirements, only the LED can meet the requirements does not contain harmful substances.
High power LEDs can also improve efficiency in many other areas. High-power LED service life than traditional incandescent long 10-15 times, 3-10 times longer than the energy-saving lamps. In fact, the durability of the LED strip technology not only can save lighting maintenance costs, but also to reduce waste generation. LED lamps with high efficiency characteristics. LED light is directional and therefore more targeted, and the LED lights higher than the traditional 180 ° astigmatism lighting performance.
Advanced technology, especially the technological advances over the past three years, greatly improving the quality of high-power LED brightness. The intensity of the color from 1-100, and 100 and the sun is exactly the same as in the visual spectrum. When the color rendering index (CRI) dropped to less than 80, see in this light, color and what the real color is inconsistent. Good color rendering index is usually more than 90. Many energy-saving light bulbs, color rendering index of 75-90, incandescent index could reach 100. The LED indicator is now more than 90 or 90. Due to recent advances in technology, whether white or color high power LED color rendering index is very high.
The early white LED blue chip covered with a phosphor. Until a few years ago, this combination can get plenty of "cold" white light, are usually used in the site and line the road. White LED for household lighting equipment such as lights in the kitchen "warm" white light. The lessons of the phosphor coat technology to improve and a wide range of products allows us to create an automatic system, different by the radiation frequency, the system can automatically distinguish between white LED cold light warm light. In the past, the choice of LED confined to "white" or "non-white". Now, some manufacturers can be white "tone" is subdivided into 50 different types.
Recent improvements of the three primary colors (RGB) LED, which was significantly improved white and color LED subtitles. Red, green and blue (RGB) LED red, green, and blue-chip package together, can emit different colors of light. Previously issued by the RGB LED color mixing light is very unstable, high-power LED driver successfully resolved the technical problems. High power of the RGB LED, such as the Lumex company's AstraLED, making the very stable, soft white light and colored light.
LED flexibility than other lighting. The compact LED systems, and sensors and other lighting controls such as dimmers, solar controller and dynamic light modulator together. High-power LED market, high efficiency, light quality. High power LED cost saving significant advantages and good performance make it become more and more choice. Now, in many homes and offices, we can see people using high-power LED technology. Future people will high-power LED application to sensor technology for automatic opening function. In addition an infrared LED technology to night vision system will be greatly improved.
Coates (Coates) Mr. Lumex's high-power technology manager, LED and LCD technology leader. Optoelectronics decade, he was involved in the industry's leading brand of LED and LCD design, which relates to the small home appliances to the aviation sector, specializing in high-power LED lighting. Mr. Coates North University of Illinois degree in electronics engineering, mail address engineering@lumex.com.
40-inch TV using the 400 1W LED 46-inch television use 450 1W LED. NEC-Mitsubishi is also in early 2004 launched a prototype of the induction light , which also uses the technology of Lumileds Lighting, the lighting system used in the NEC-Mitsubishi backlight Lumileds Luxeon high-brightness LEDs. However, according to Zhou said, the future Lumileds' market focus is high-power fields, including automotive lamps and LED lighting applications.
Also been part of the photoelectric enterprises to solve the problem of the LED-TV technology, Guangdong Asian lighting is one of the representatives. The author in December 2008 interview with its chairman Wu Wenfeng, it learned that Asia from the 2006 TV-LED backlight system of the core technology, and building a domestic annual output of 130,000 LCD-TV LED backlight module production line, has successfully developed from 19 inch to 52-inch LCD-TV LED flashlight products. Technical cooperation of the Asian one with Hisense Company the world's first 42-inch LED-backlit LCD TV has been officially launched in China market.
I recently interviewed the general manager of Shenzhen Ruifeng Gong Weibin that Ruifeng power is also LED TV backlighting with some domestic TV manufacturers, to seize the next few years, trends in the market. The Gong Zongshun potential it comes to LED downlight industry due to low investment threshold and skill levels, leading to confusion in the market and disorderly competition. However, with large industrial giant (TSMC, Foxconn, etc.), the whole industry will accelerate the shuffle, there is no technological competitive advantage and financial strength, business is bound to die out, the fate of such enterprises or the acquisition, shares, bigger and stronger; after a face-lift or pick up, take the road of production foundry.
Who has mastered the technology and market opportunities in a rapidly changing LED industry, grasps the future development of the initiative. But the natural weakness of the market is driven by greedy interests, more and more manufacturers are targeting the LED tube market will lead to waste of duplicate construction and a lot of money, resources, prices will decline rapidly, diluted profit, the blue ocean market today will will become the Red Sea a number of enterprises Ebb Tide survive, another group of the victims turned into cannon fodder.
Therefore, any stage of a technology development and promotion is bound to be driven by an industry reshuffle, the only real quality well, manufacturers can market through the development of the LED backlight and grow, but there are also some immature technology, the strength of the weak enterprises will be eliminated. We can foresee that there is such a number of development and growth of the LED with the LED backlit TV market capacity expansion l. Only the market never waits for no man run faster than the market can be bigger and stronger.
According to the wholly-owned subsidiary of the Philips Lumileds Asia Pacific Marketing Director Zhou Xuejun, as early as 2004, Sony introduced the world's first LED downlight backlight LCD LED TV, which uses Lumileds Luxeon high-brightness LED as a backlight to improve color reproduction. Sony introduced two high-end "Qualia" TV with LED backlight technology, including a screen size of 40 inches, and another 46 inches.
Recently, the Skyworth Group Vice President, TV Business Division President Yang Dongwen in a media interview, said that Skyworth will be listed on the National Day of the thinnest 24.7 mm LED LCD TV, the world's thinnest electronic ballast flat panel TV in South Korea's LG in June of this year on the 25th, a 24.8 mm thick LED TV. He said Skyworth LED LCD TVs are more advantages than the traditional LED strip liquid crystal, but before the technology has been for foreign brands dominated, Sharp, Sony, Toshiba, Samsung and a few other brands to launch small and medium size, and in China LED TV sales still in a very high price. According to market feedback, the Sharp 52-inch LED tube price of 10 million ordinary LCD TV.
Skyworth said, they would begin early in 2005 put into the development of LED backlight, through the efforts of more than 2 years, and finally to achieve technological breakthroughs will be the National listing of LED LCD TV power consumption than LCD TV is more than 30% reduction in life of up to 100,000 hours, enough users to spend 20 years. At the same time, color reproduction is better, richer color, dynamic contrast ratio of 40000:1, screen layering stronger. I learned from some industry sources, LED TV, the concept of existence understanding of the differences. Actually refers to the LED TV LED flat-panel TVs, currently on the market launch of the LED backlight TV, just uses LED backlight LCD TV --- replace the backlight LED panel or the LCD.
The world's largest LCD TV maker Sharp has been listed in China three LE700A Series LCD TV with LED backlight technology. According to the person in charge of the Tsinghua Tong Fang had revealed to the media, its 19 inches, 22 inches, 26 inches and 32 inches of the small size of LED LCD TV plans to be available before the National Day this year, 42-inch large-size products will have on sale at the end. Hisense has also told the media that will soon be launched 42,47,55 inch LED TV. Can be predicted that the fight between the LED light bulb -backlit LCD TV makers will reach a fevered pitch. This round of upgrade war by Sharp, Samsung and other foreign brands as the leading domestic brand Hisense, Konka and Skyworth is quickly moving up, the LED industry is also bound to set off a new round of the competition. LED backlight TV why favored?
It is understood that the LED backlight technology to improve the color rendering capabilities of the image display, flat panel TVs using the traditional cold cathode fluorescent lamp (CCFL) for the backlight, and usually does not have a particularly strong emission in the red spectral bands of the visible spectrum, this means that you can not are well reproduced on the screen in red. LED back lighting method, the red display intensity. LED with than cold cathode fluorescent lamp (CCFL), high color gamut, high color saturation, faster LED bulb can help eliminate the "tail", etc., can be a the CCFL good alternative products.
So this does not rule out a number of flat-panel LCD TV manufacturers, the concept of speculation, like before air conditioning industry has provoked much discussion, "DC inverter air conditioner, but this is actually a call to problems businesses intentional acts of speculation. Of course, although there are a variety of questions, whether from the perspective of consumers use from the point of view of technological progress. LED-TV, or an irreversible trend. Currently up to say yes, LCD TV in the next few years will be replaced by LED TV. It is estimated that the cost of the LED is controlled at 1.5 times less than the CCFL (cold cathode fluorescent lamps), the market will be completely different, it is estimated that over the next three - four years, the rapidly falling prices.
Professional market research firm DisplaySearch, the latest survey data indicate that the LED-backlit LCD TV panel shipments in 2009 was estimated at 3.6 million, LED-backlit LCD TV ratio is estimated that less than 3% in 2010 will grow to 100 million to 5.1 million, 2013, rapid growth to 40% is expected in 2014 will have the opportunity to more than CCFL backlight shipments. The same time, the 2013 large-size LED backlight (referring to 10-inch and larger) panel shipments will grow about 4.9 million in 2009 to 400 million $ 4.8 million overall LED backlight market share is estimated at 54.3%, the LED backlight will become mainstream.
For the electronics manufacturing world's leading market research firm iSuppli statistics pointed out that in 2009, about 105 million TFTLCD panel with LED backlight technology, market demand for LED market size of $ 163 million, and expects that figure 2012 will grow 9-fold to $ 1.4 billion. iSuppli and expects the penetration rate of LED backlighting technology will be 3% in 2009 to 2013, when about 39%.
late at night with pedestrians or vehicles, through the sensor detection, such as infrared image detection, automatically open in front of 5 street lamp, delay 3 minutes after the closure, to achieve further energy-saving LED lights. Analysis of a variety of lighting the luminous efficiency can be seen that the luminous efficiency of a variety of light sources are rising, which requires us to take full advantage of the other characteristics of the LED to enhance the energy saving effect of the LED light source. Semiconductor lasers is an important part of semiconductor lighting The semiconductor laser is a special form of the LED or LD, it is the fundamental difference between ordinary LED is a single frequency, the energy concentration.
Semiconductor lighting, we are very concerned about the characteristics of the LED luminous efficiency and lumen maintenance and life. For example, pre-unwritten consensus, that is, single-tube LED light efficiency is less than 80lm / W not used for street light , the luminous efficiency requirements onto the market the LED lamp products indeed have the light fades the question is useless to replace on how long it begins with the poles down, so far, remains particularly concerned about these two issues.
In fact, semiconductor lighting development to the luminous efficiency by 2001 standard white LED (20 mA) luminous efficiency of 25lm / W development to a the Nichia published in early 2009, white LED at 20mA, the luminous efficiency of up to 249lm / W , most of the industry. The luminous efficiency of high-power white LEDs (350mA) from 2004 about 30lm / W development to the end of 2008, Cree issued 161lm / W products, is currently an industry best. Now, no matter the efficiency of LED light or the light fades, there is a fundamental improvement. The development of semiconductor lighting industry: LED lamp with power supply and control circuit,
LD (semiconductor laser) lighting and semiconductor lighting supporting policies must draw our attention. The power supply reliability, and control circuit is the fundamental guarantee of LED lighting to promote According to statistics, the white energy saving lamp failure fault, about 70% of power problems, about 20% of the lines and structural problems, fewer than 10% of the LED single tube quality problems. The choice of power management solutions for energy saving in terms of position, which requires to select the most suitable AC-DC drives in the drive circuit design. Common two AC-DC drive power unit efficiency of 85%, with efficiency of 90% constant current IC, the overall efficiency of only 77%.
Assumption that the luminous efficiency of 100lm / W LED tube, only the power efficiency of road lighting efficiency down to 77lm / W (not yet take into account the secondary light distribution and other losses). High-efficiency AC-DC drive power as a whole module can achieve a conversion efficiency of 90%, so I chose to efficient, reliable power is critical of the semiconductor energy-saving lighting. Assume that the luminous efficiency of high pressure sodium lamps and LED lights are 100lm / W, the strong point of the LED tube in the same road illumination, you can save electricity 50% (and incandescent saving 80%) about this a characteristic has been known. But LED lights some features better than high pressure sodium lamps,
have not attracted much attention and use of, for example, through the control circuit controlled the characteristics of brightness and the LED lamp instant start features have not been widely used. We use these features, the control circuit can achieve the timeshare brightness control and the necessary open, so saving 50% of the indicators, so that the LED lights energy-saving effect further enhance. At night, according to the pedestrians, the number of specific conditions and the natural environment, we can be divided into the time control of LED lights of different brightness, or directly shut down,
Semiconductor lasers are widely used in laser sights, laser typesetting, laser medical treatment, laser ranging, laser communications, laser pointer, laser storage, gaming, military, barcode scanning, children's toys and landscape lighting, stage lighting, laser show and other fields, including landscape lighting, stage lighting, laser show is an important part of the semiconductor lighting.
Produce LED lighting products pose hazards. LED downlight is mainly reflected in the eyes of radiation hazards near UV radiation damage, retinal photochemical damage and Blu-ray radiation of heat damage and so on. LED lighting products, many consumers react more easily than ordinary incandescent cause eye fatigue, even if there is a high-tech products and then a strong performance, do not use on human health, then such products consumers will not pay it!
Based on the above points, I hope the government and enterprises from the viewpoint of consumers, developed a high-quality, affordable, healthy, environmentally friendly LED lighting products, LED products can make a sound to the average consumer, the benefit of mankind.
Whether the quality of LED lighting pass. LED Light products will eventually replace incandescent lamps, this trend is unstoppable, but also raises the investment boom of the LED products, such as high-end LED lamps have a relatively complex structure, consumers see only the head, but do not to chip, drive, cooling, and software, which makes the current market there is a variety of mixed, mixed LED lighting products, reliability is poor, life is short, uneven color of light as a major quality problems. In just a few years, these problems can be well resolved, we look forward to.
Second, LED lighting product prices. The current high price of LED Lamp products become the biggest obstacle to ordinary consumers, although the last two years the price of LED lights gradually decline, technology continues to improve, but a home 9 watt LED lamp, the price on the hundred dollars, which is usually used a few dollars incandescent ordinary consumers, a far cry from the long-term perspective, perhaps, LED energy-saving products, energy-saving high-performance, long life characteristics of the resources, enough to pay for its high price. But companies must not ignore the Chinese people's spending habits, consumers can only see the immediate benefits, despite government support, some companies try to use the EMC model, the present situation, the effect is not obvious .
According to the Japanese retail research firm GfK Japan sinks the whole of Japan, 4,000 home appliance discount store sales data, in December 2011 Japan installed in places such as ceiling lights ceiling (ceiling light) sales over the same month of 2010 jumped 58%, One result of the Japanese consumer awareness on energy conservation, coupled with declining prices to drive sales of LED ceiling lights up to 47% of the total share, accounting for more half a year ago showed 15% doubled. GfK said, LED products, power consumption can be reduced compared with 2-3 percent fluorescent tube products, plus up to 10 years of life, LED bulb ceiling lights for the main reason accounting for surge.
GfK said in December the average price of Japanese LED ceiling light about 2.8 million yen price in the past year fell by 3 percent, some of which the heart of Tokyo, home appliances discount stores have emerged ￥ 15,000 products, between products and fluorescent tubes price differential has been reduced to 5 percent. GfK also pointed out that in December 2011 compared with sales of LED bulbs in Japan the same month of 2010 jumped 63%, the proportion of the total light bulb sales by 37%, accounting since July 2010 record high.
Ministry of Industry and Information Technology vice minister, the Union Honorary Chairman Yang Xue Shan said China's semiconductor lighting / LED industry alliance formed with the application of great significance. LED Light Bulb industry needs a huge, huge market, competition, industry chain parties enterprises urgently need to strengthen coordination and cooperation. Lighting is the economy and society, people live without the products, but lighting a great power, either from energy or from the environmental point of view, a huge number of traditional lamps need to replace the need to accelerate innovation. At present, LED lighting innovation has become the main direction, revealing a huge market potential. Developed countries and regions, many companies are stepping up the layout of the LED industry, the competition between the international giants, giants and international competition among Chinese companies is fierce. LED industry chain length, each chain has a large number of Chinese companies, but not closely cooperate with each other. Therefore, to form a coalition is necessary.
LED industry is the world's most promising emerging strategic industries with high industry growth, technology advances faster, stronger leading role, the market prospects and so on. The world's major countries and regions to develop LED panel light industry, the formation of the United States, Japan, the European Union leader, South Korea, China's rapid development of industry structure.
China has published a number of policy measures, a strong impetus to the rapid development of LED industry. Data show that in 2011 China's LED industry output value reached 154 billion yuan, an increase of 22%, production up 50%. 2012, industry output is expected to reach 200 billion yuan, an increase of 30%.
In recent years, China's LED industry, technological innovation has improved significantly, with the international advanced level of gap continued to narrow. Product application areas show the direction from the more mature, landscape lighting and other areas, to large-size LCD display backlighting, automotive lighting, road lighting, general lighting and other areas of extension.
Do not move, to take pictures." Yesterday evening, the major road junctions in urban areas, have lit a light square shape, exquisite, a large number of people gathered to watch and take pictures.
China Plaza East "Eight Horses Pentium" shape just set up the lights, turn on the LED Light in the evening for the first time, immediately attracted many people and photographers to come. Against the "debut" of the light version of "Eight Horses", we have to take pictures. "Did not go home to visit relatives for several years, and nothing to the home at night, out walking the streets found many nice lighting design, and found the home becomes more and more beautiful." Rushing home from the field Mr. Xue said the New Year
"'Ten thousand ten cities' has just launched soon, our" Crystal Day lighting "have a lot of sweetness." Jie said, LED Lamp revolution will no doubt cause, although there is still a long way to go, but the enterprise or even industry confidence has been nurtured.
As a major city in line with industry planning and to promote the cultivation of business objects, "Crystal Day lighting" with their own LED panel light on the quality and quantity of benefits, has contracted the "South Lake Avenue, street Weiliu Road Project", "Huzhou Taihu Lake Road Reconstruction (north of the highway) lighting project, "" Eternal Road Longshan District Lighting Project "," 98 hospitals LED street lamp project, "" clothes Street Historic District Lighting Project "," Anji Anji Avenue street project "and other projects, range of product applications and new product development projects launched by the full recognition at all levels.
End of last year, the city's downtown LED downlight landscape lights in the application of the total number of 120,000 or more, "Ten thousand ten cities," this "big cake" is cut into different sizes of the "cake pieces", one after another into the city more than 30 energy-saving electric light source manufacturer's hands.
Currently, downtown bronze Road, Hongfeng Road, Xinhua Road, Huzhou Development Zone of the Second Ring Road, Phoenix Road, namely, strong way, Wuxing the road by six, by Rd, State Road 318 (Huzhou), the Xuefu , Bachelor Road, customs section, Nanxun government buildings and so has been to promote the use of LED lights. As the application of LED lighting in the tunnel project, 104 State Road, Castle Peak in the tunnel made the attempt, now that the tunnel has been the application of LED lamps 400.
According to the Municipal Technology Bureau, responsible person, the end of February last year, China launched a "Ten thousand ten cities' plans to deploy, the city's" city of ten thousand ten "leading group on the first pilot province to the city - Ningbo, Hangzhou City learning research, and based on their advanced experience, the actual situation against Huzhou, developed the "Huzhou City," City 10000, "semiconductor lighting application engineering implementation."
Since the construction of the pilot cities, the city semiconductor LED lighting according to the characteristics and local urban lighting master plan, highlighting Lake in Huzhou, ecological, landscape garden city, modern elegant integration of LED Light Bulb highlights, combined with energy-saving, environmental protection, ecological principles, the further implementation of the lighting, lighting project. In road lighting, scenic lighting, indoor lighting, urban construction of major projects, etc., adhere to government guidance and market operation combining, product development and promotion of application of the combination to accelerate implementation of LED lighting demonstration project. "Program" and requested, from 2011, all levels of government investment in new or renovated road lighting, landscape lighting and other public facilities (including government offices, libraries, museums, stadiums and other places) on the first engineering principles lighting applications with LED the product. Especially for non-government entities are responsible for the new shopping centers and other large buildings, such as interior lighting with LED lamps, LED application was listed as demonstration projects, the city will give some financial assistance. Seeking Information Electronics Co., Ltd. Zhejiang Vice President Cai Lili said: "This is not only manufacturers of LED lighting is a stimulus, but also the application of LED lighting's a little encouragement to the LED lamps manufacturing and related industries are a big boost the role. "
"'Ten thousand ten cities' is come out of the 'big cake', Huzhou all the LED industry-related businesses will be a profit." Jing Jie on Lighting Technology Co., Ltd. Vice President told reporters that "five" period, or the city will be the rapid development of LED industry an important opportunity, "'Ten thousand ten cities' illuminate not only the enterprise, as well as the future of the industry ..."
Last May, announced the Ministry of Science, Beijing and other 16 cities for the second installment of "Ten City, 10000," semiconductor lighting application engineering pilot model city, the city is one of them, become second only selected cities in Zhejiang Province . Encouraged by this, the city of LED-related enterprises in the economic winter, the confidence to increase investment, sounded share "Ten thousand ten cities," Chong Fenghao cake.
At the same time, the city part of the reflection of the LED industry leaders have begun to precipitate, "Ten thousand ten cities," What will Huzhou LED spotlight industry? The most pressing business job? How to grab the market to reverse the traditional private economic development ideas?
"'Ten thousand ten cities' has just launched soon, our" Crystal Day lighting "have a lot of sweetness." Jie said, LED lighting revolution will no doubt cause, although there is still a long way to go, but the enterprise or even industry confidence has been nurtured.
As a major city in line with industry planning and to promote the cultivation of business objects, "Crystal Day lighting" with their own LED light on the quality and quantity of benefits, has contracted the "South Lake Avenue, street Weiliu Road Project", "Huzhou Taihu Lake Road Reconstruction (north of the highway) lighting project, "" Eternal Road Longshan District Lighting Project "," 98 hospitals LED street lamp project, "" clothes Street Historic District Lighting Project "," Anji Anji Avenue street project "and other projects, range of product applications and new product development projects launched by the full recognition at all levels.
End of last year, the city's downtown LED downlight landscape lights in the application of the total number of 120,000 or more, "Ten thousand ten cities," this "big cake" is cut into different sizes of the "cake pieces", one after another into the city more than 30 energy-saving electric light source manufacturer's hands.
Currently, downtown bronze Road, Hongfeng Road, Xinhua Road, Huzhou Development Zone of the Second Ring Road, Phoenix Road, namely, strong way, Wuxing the road by six, by Rd, State Road 318 (Huzhou), the Xuefu , Bachelor Road, customs section, Nanxun government buildings and so has been to promote the use of LED lights. As the application of LED lighting in the tunnel project, 104 State Road, Castle Peak in the tunnel made the attempt, now that the tunnel has been the application of LED lamp 400.
According to the Municipal Technology Bureau, responsible person, the end of February last year, China launched a "Ten thousand ten cities' plans to deploy, the city's" city of ten thousand ten "leading group on the first pilot province to the city - Ningbo, Hangzhou City learning research, and based on their advanced experience, the actual situation against Huzhou, developed the "Huzhou City," City 10000, "semiconductor lighting application engineering implementation."
Since the construction of the pilot cities, the city semiconductor LED lighting according to the characteristics and local urban lighting master plan, highlighting Lake in Huzhou, ecological, landscape garden city, modern elegant integration of LED lighting highlights, combined with energy-saving, environmental protection, ecological principles, the further implementation of the lighting, lighting project. In road lighting, scenic lighting, indoor lighting, urban construction of major projects, etc., adhere to government guidance and market operation combining, product development and promotion of application of the combination to accelerate implementation of LED lighting demonstration project. "Program" and requested, from 2011, all levels of government investment in new or renovated road lighting, landscape lighting and other public facilities (including government offices, libraries, museums, stadiums and other places) on the first engineering principles lighting applications with LED the product.
Recently, China's semiconductor lighting / LED Light industry alliance established in Beijing with the application. It is reported that the Alliance is based on the spirit of the State Council, the Ministry of Industry and Information Technology, by more than 150 domestic LED companies, lighting companies and industry associations, standards organizations, testing agencies and other units jointly sponsored the establishment. The Alliance was founded to promote the semiconductor lighting, LED industry healthy and orderly sustainable development; advance semiconductor lighting, LED industry chain coordination development; help companies to do good, bigger and stronger.
Ministry of Industry and Information Technology vice minister, the Union Honorary Chairman Yang Xue Shan said China's semiconductor lighting / LED Lamp industry alliance formed with the application of great significance. LED industry needs a huge, huge market, competition, industry chain parties enterprises urgently need to strengthen coordination and cooperation. Lighting is the economy and society, people live without the products, but lighting a great power, either from energy or from the environmental point of view, a huge number of traditional lamps need to replace the need to accelerate innovation. At present, LED lighting innovation has become the main direction, revealing a huge market potential. Developed countries and regions, many companies are stepping up the layout of the LED industry, the competition between the international giants, giants and international competition among Chinese companies is fierce. LED industry chain length, each chain has a large number of Chinese companies, but not closely cooperate with each other. Therefore, to form a coalition is necessary.
LED panel light industry is the world's most promising emerging strategic industries with high industry growth, technology advances faster, stronger leading role, the market prospects and so on. The world's major countries and regions to develop LED industry, the formation of the United States, Japan, the European Union leader, South Korea, China's rapid development of industry structure.
China has published a number of policy measures, a strong impetus to the rapid development of LED industry. Data show that in 2011 China's LED industry output value reached 154 billion yuan, an increase of 22%, production up 50%. 2012, industry output is expected to reach 200 billion yuan, an increase of 30%.
In recent years, China's LED tube industry, technological innovation has improved significantly, with the international advanced level of gap continued to narrow. Product application areas show the direction from the more mature, landscape lighting and other areas, to large-size LCD display backlighting, automotive lighting, road lighting, general lighting and other areas of extension.
It is reported that after the establishment of the alliance, the main tasks include promoting the semiconductor lighting / LED industry's core technology and product innovation, and promote scientific and technological achievements into practical productive forces and so on. In addition, including the promotion of semiconductor lighting / LED industry, the public service system, technical standards and research.
