More LED-related content, please visit: www.bgocled.comLED lights as a new product, now the current North American product safety standards do not specifically address the technical requirements of such products, LED products, the industry as a test subject. U.S. UL Laboratory for the current industry conditions, is organizing the preparation of LED light safety certification standards UL8750, this standard is still a draft, not being formally adopted as the certification standard. Thus, LED energy saving lamp certification test questions, not being completely resolved.
The basic principle of energy-saving LED lights by switching power supply module to the AC power into DC to power the light emitting diode. According to the basic principles of energy-saving LED lights and structural features, MET Laboratories, the U.S. proposed a transitional stage of the testing program: the use of traditional energy-saving lamps U.S. certification standards UL1993 (corresponding to the Canadian Standards CAN/CSA-C22.2 No. 0, CAN / CSA-C22.2 No. 74), and power modules standard UL 1310 or UL 1012 (corresponding to the Canadian Standards CAN/CSA-C22.2 No.107) of the LED lamps for testing and certification.
Second, the detection techniques
Following on the basis of UL1993, UL 1310 and UL 1012 standards, certification testing of LED energy saving lamps in the key issues, do some elaboration.
1 Materials
LED lamps can be made into various shapes, with fluorescent tube LED energy-saving lamps, for example, its shape, as with ordinary fluorescent tubes, fluorescent tube transparent polymer shell by the power module and the light-emitting diode package inside. Transparent polymer shell fire and play in the product's features electric shock. According to standards, energy-saving lamp shell material is required to achieve V-1 grade or more, so transparent polymer shell to be used more than V-1 grade material. Point to note is that the product enclosure to achieve the required level of V-1, its thickness must be greater than or equal to V-1 grade of raw materials to the required thickness, fire rating and thickness of the raw materials required in UL yellow card check to. Found in the actual testing, the manufacturer in order to ensure the brightness of LED lights, often very thin transparent polymer shell, which requires attention to ensure that materials testing engineers reached the required fire rating thickness. Since different materials have the same fire rating requirements of different thickness, some raw materials in smaller thickness to meet the higher fire rating requirements, recommended that manufacturers can choose the right materials to do the product casing.
(2) drop test
According to product standards, to simulate the actual use of the product may occur during the fall drop test case for the product fell from the height of 0.91 meters hardwood board, the product can not be broken shell as well as the risk of exposing the internal live parts. Product manufacturers choose to do shell material, the need to consider the strength requirements.
3 electric strength
Surrounded by a transparent shell in the power module inside the transparent casing material must meet dielectric strength requirements. According to standards, based on the conditions of the North American voltage of 120 volts, the internal high-voltage live parts and case (covered with foil test), to be able to withstand 1240 volts AC electric strength test. Under normal circumstances, the product shell thickness of about 0.8 mm, which can meet the electric strength test requirements.
4 power supply modules
LED power supply module is an important part of energy-saving lamp, power supply module of the use of switching power supply technology. Press the power module types, consider using different criteria for testing and certification. If the power supply module is a class II, which can be used to test UL1310 certification. class II power supply is the use of isolation transformer, the output voltage is less than 60 volts DC current is less than 150/Vmax amp power supply. The power of non-class II, is used to test UL1012 certification. The technical requirements of these two standards are very similar, can cross-reference. Most of the internal power supply LED light module is associated with non-isolated power supply, power supply output DC voltage greater than 60 volts, it does not apply UL1310 standards, and applicable to UL1012.
5 insulation requirements
Because LED lamps inside the limited space, the structural design, to pay attention to hazardous live parts and accessible metal parts between the insulation requirements. Insulation can be a distance and creepage distances, it can be insulating film. According to standards, hazardous live parts and accessible metal parts to distance between 3.2 mm and creepage distances to reach 6.4 mm. If the distance is not enough, you can add insulation film as an additional insulation, the insulation thickness is greater than 0.71 mm, if the thickness is less than 0.71 mm, the product will have to be bearing 5000V high voltage testing.
6 temperature test
Temperature rise test is a product safety testing must be done, standards for the different components have a certain temperature limit. In the product design stage, the manufacturer must pay great attention to the heat dissipation problem, especially for some parts (such as the insulation film, etc.) should pay particular attention.
Components if long-term work in high temperature conditions, easily damaged, resulting in fire or electric shock. Inside the lamp power supply module in a closed confined space, heat dissipation is restricted. Therefore, manufacturers component selection, we should pay attention to select the appropriate components of the specification, to ensure that components in a certain margin to work, thus avoiding long-term components under conditions of near full load of work arising from overheating.
7 Structure
LED lamps installed in the power module inside the housing, space is limited, and some manufacturers in order to save space, the surface of the pin-like components soldered on the PCB, this is unacceptable. The surface of the welded pin-type components are likely to fall off because Weld and other reasons, causing danger. So take these components as much as possible welding jack. If forced to take the surface of the welding, will have to glue these pieces plus a fixed component used to provide additional means of protection.
8 fault test
Failure of the product certification testing is critical to test a test project. This test project is on the line short or open some of the components, to simulate the actual process failures that may occur, in order to assess the product in a single fault conditions of security. In order to meet the safety requirements of the product design, consider the product plus the appropriate input fuse to prevent short circuits or internal components, output overcurrent faults resulting fire hazard.

2011 Japan ranked environmental goods - LED lights much attention

With energy-saving trend higher, probably the most talked about products to the number of LED (light emitting diode) bulbs. In the survey, after the earthquake in the selection of goods for more attention to the area when asked, the answer is the largest number of fluorescent lamps, lamp 38.1%. In the three years to purchase 77.5% of consumers care about that ring ...With energy-saving trend higher, probably the most talked about products to the number of LED (light emitting diode) bulbs. In the survey, the "earthquake more attention in the selection of merchandise areas," the inquiry, the answer is the largest number of "fluorescent lamp" of 38.1%. In the three years to purchase 77.5% of consumers said "concerned about environmental protection."

More LED-related content, please visit: www.bgocled.comToshiba company is ranked first prize. Number of people buying the same top. However, evaluation of environmental performance of the individual, the situation is slightly different. 10 projects, 9 projects Panasonic ranked first in the next want to buy companies, ranking higher than the Toshiba, Panasonic.
Although the survey alone is difficult to draw conclusions, but according to common sense reasoning, Toshiba's evaluation of environmental goods to be the reason why, is not that the environmental performance, but from its use of LED light bulbs contribute to environmental attitude, For example, in 2009 launched the first practical large-scale enterprises in the level of the LED light bulbs, incandescent bulbs in 2010 first cut-off and so on.


2011 Japan ranked environmental goods - LED lights much attention
LED will completely replace incandescent
LED bulbs come in only two and a half years, prices fell sharply, has entered the popular stage. However, Toshiba Lighting Technology Light Division, Ministry of goods act goods LED head Yuji Takenaka said: "The brightness of the newly unified method token lumens, the company's specifications have been able to compare with each other, but the market is not mature."
Company's sales approach has undergone tremendous change. Initial emphasis on energy saving, long life are well known. This summer, many consumers who buy energy-saving LED light bulbs is one of evidence.
Today, the company is working to expand the product line. To compensate directive, on the back of the LED bulbs are more dim shortcomings to light with a wider range of high light-based products are gradually come out.
Panasonic has put in a special small tilt chandelier installed krypton bulbs, Toshiba will launch in November bulb color, and brightness and 60W incandescent bulb with 810 lumens of LED light bulbs. Replace incandescent bulbs in order to obtain the demand, companies are racing to develop.
Panasonic Appliance Wellness Division marketing manager of the original goods Zhaoyi Lang said: "I hope to lift (line) 'missing teeth' of the state."
In the future, the eye of the typhoon is expected to become the market probably will 爱丽思欧雅玛 and other low-priced goods. The company's environmental performance evaluation, though not outstanding, but the number of people buying highest in the first three, the next time also want to buy the company discharged the first four. This probably shows that consumers are dissatisfied with the price of LED bulbs is still big.

Neo-Neon LED market bleak six months loss of HK $ 102 million

Neo-Neon (01868.HK) to loss of semi-annual report (2011 April 1 to September 30) to reflect the dismal state of the LED lighting market at home and abroad. Yesterday, the really bright half 2011 financial results release, as of September 30, really bright in the first half revenue of HK $ 788 million, an increase of 7.9%, loss of 102 million Hong Kong ...

More LED-related content, please visit: www.bgocled.comNeo-Neon (01868.HK) to loss of semi-annual report (2011 April 1 to September 30) to reflect the dismal state of the LED lighting market at home and abroad.
Yesterday, the really bright half 2011 financial results release, as of September 30, really bright in the first half revenue of HK $ 788 million, an increase of 7.9%, a loss of HK $ 102 million. Neo-Neon in the earnings report, said the economic environment deteriorated, leading to customer limit orders generally shrink. The LED over domestic investment, leading to an oversupply of LED production capacity significantly, the rapid decline in market prices.
Reported a first half revenue growth of Neo-Neon completely from the beginning of the acquisition of overseas companies HCI, HCI overseas companies contributed HK $ 219 million in revenue. If the income of foreign companies to remove HCI, really bright in the first half revenue was only HK $ 569 million, down 22.1%.
Neo-Neon Chairman Ben FAN that economic weakness in Europe and America, a direct result of customer orders decline. The company has passed to raise the market share of Chinese and European markets offset the impact of the recession, the Chinese market is expected to become a major source of profit.
LED industry, serious overcapacity, so that really bright and rapid decline in gross margin. Reported a gross profit margin of Neo-Neon products from 33.1% last year, quickly fell to 13.7%, down nearly 20 percentage points.
Neon said soaring raw material prices, labor costs and appreciation of the renminbi, resulting in decreased product gross margin, and the company expanded to the upstream LED epitaxial film business, making a substantial increase in cost of equipment depreciation. It is reported that the current Neo-Neon has 19 sets of MOCVD equipment (LED wafer production equipment) operation, the monthly production capacity of 55,000 LED epitaxial wafers.
Many LED companies expect out incandescent Development and Reform Commission announced roadmap and LED lighting products yet to start two messages of government subsidies. However, a high-level LED lighting that now the family is basically using fluorescent, little more than a 60 watt incandescent, so figure out incandescent lighting to promote the development of LED, the LED market is expected illusory. The LED lighting products in government subsidies has not exactly news, even if implemented, may be little benefit of the LED business.
In fact, riding a tiger, all involved in upstream LED enterprises face the embarrassing situation.
Neo-Neon LED upstream of the first half because of investment, and access to domestic subsidies to 43.1 million yuan of local government. Yesterday, German Runda (002005.SZ) has announced, through a wholly owned subsidiary of BDO International, Yangzhou Runda BDO Runda increase $ 35 million capital increase of Yangzhou BDO Runda registered capital of 7,500 million.
"Local government subsidies, with the LED in place of the enterprise issued by MOCVD equipment, LED companies to honor their commitments and access to local municipal lighting orders, usually bite the bullet." One of the LED industry analysts pointed out that this will only lead to LED overcapacity situation worse. Because, once the MOCVD equipment production, taking into account the cut-off of losses, we will not stop.

Four LED lighting industry, global analysis of the regional status quo

With the increasing global energy depletion, surface temperatures continue to rise, energy saving consciousness of mankind to gradually strengthen, with the concept of energy saving LED industry blossom, shine in the world, Ever since the LED industry seems to have become savior of the world lighting industry, various government land in Europe in the next financial crisis, confusion seems to find the industrial revitalization, a good way of raising the employment rate, the land of China is celebrated by the whole country, that finally found Overtaking, creating the world good opportunity for first-class technology, any technology, lighting are all busy with industry called on the government funding, support, subsidies LED industry, hoping to teach LED lighting replacement overnight to any corner of the world, immediately lower the global temperature twice, especially in the China's various industries all wished he could squeeze into the LED lighting industry to sub to that so-called 500 billion or even trillion dollars of the "big cake."
But is this really so? Our LED lighting technology has reached overnight will be able to replace all light level? Let's take a closer look at the industry level and national level in the end the world is what happens?
First, the European
Market: As the Europeans more mature awareness of environmental protection and energy saving, environmentally friendly products, a high degree of acceptance, coupled with the European Union first proposed the elimination of incandescent light has begun to implement the relevant laws, governments in energy-saving lamps and LED lamps have been offering applications the subsidy program (subsidies amounted to a price of 30% to 55%), so in the global arena, the European market in the popularity of LED lighting applications and promotion rates are higher, some of the major countries in Europe have begun to supermarkets high-volume sales 10W LED bulbs and spotlights the following products, European lighting giant Philips and Osram has Frankfurt Lighting Fair in 2010 unveiled its application on large-scale product line, and began the construction and promotion of market channels.
Technology: As the EU countries in the development of uniform standards, often due to national interests and different starting point, resulting in many systems and the specification on a sluggish, in Europe related to market access and technical threshold is relatively loose, CE in for Solid State Lighting (SSL) in The draft technical amendments to the majority of the light is still some of the technical requirements of traditional light sources, there is no big changes.
Enterprise: as traditional European lighting giant Philips and Osram has invested heavily in the year 2000 that began the study of basic technology of LED lighting, including Osram white LED with a fluorescent material has been a leading edge, but Osram recent years has been a big seller in the market in Indonesia packaged white light beads, in the general types of lighting products to promote the field of small and mainly concentrated in the interior light bulb and lamp module class promotion; and Philips Pu is the great advantage to bring their capital, the first in LED applications and other acquisitions of U.S. companies lumileds program the company has technical advantages in obtaining core technology and patents related to the market in mainland China after finding high-quality mining and manufacturing enterprises to help him do OEM production, and with very stringent criteria and a large order for the bait to maximize the compression OEM profits.
Alternative analysis: Philips and Osram LED lighting in 2012, the promotion will focus on European and American markets, this two wolves after 2012 the use of large-scale manufacturing enterprises in mainland China into the Asian market, the use of China accumulated in the application of technology experience for them to earn huge profits.
Second, the Americas

Market: As the financial crisis, Americans are beginning to pick up the calculator preoccupied with their expenses, LED lighting products for the traditional lighting of the real price is higher than, the U.S. has always been very generous and see some hesitation, so being in the major markets and supermarkets also see LED lighting applications shelves and large-scale promotion, occasional sporadic to see only some of the low-voltage products like flashlights and night light.

Technology: Americans are very strict in terms of market access, in addition to other than the Energy Star standards, UL standards for solid-state light sources are developed and gradually introduced the draft, and also associated with other access standards are also being developed and consultation, although LED application products are European and American companies to do flicker too fast chip, much once the momentum toward the consumer market around the world, but because of the high cost of UL certification and cumbersome, LED solid state lighting market really started in the North American market is estimated in 2012.

Company: United States CREE, lumileds, bridgELux other companies, led by a group of LED chip manufacturers seize the core technology of LED chips in the world non-stop flicker LED technology has completely replaced the traditional lighting of the world factory - China, quickly start applications development and production of it, we need your U.S. products, while they are up to 70% of middle and lower profit margins traction applications large number of enterprises purchasing their products, on the other hand the lead organization of associations or even their own alliance to develop products that are lower than the technical standards, the manufacturers in mainland China as their testing ground for immature technology.

Alternative Analysis: Americans in the field of LED technology is second-rate, but a means to promote American business is absolutely world class, from CREE company to Shuji Nakamura, the Japanese dug from the United States will be able to see that Americans like the one marked by , the LED industry in the future, he will spare no effort to make use of their hegemony and market leadership firmly in control high-end chain links, the so-called 500 billion dollars for the market to grab most of the cake.

Third, Asia, Japan, Korea and Taiwan

Market: ultra-high brightness blue LED technology to engage in the eighties by the Japanese out, so the Japanese society for LED lighting applications have the world's highest passion, so the Japanese market for LED applications, support for very large, with in recent years the government launched a strong integration with the redemption plan of LED products, LED products in the Japanese market, sales growth has been far ahead of other countries; and for South Korea and Taiwan because of its more mature semiconductor manufacturing and R & D technology, the current full 70% of the world in high-end LED chip manufacturing is done in this area, and even Japan's Nichia, Citizen, Osram, the United States bridgelux, semileds so almost most of them are OEM production in Taiwan.

Technology: Japan is still far to grasp the highest brightness LED production technology, and packaging used in high-grade phosphor technology, but technology as the Japanese blockade, the Chinese people will always get people's Ersan Liu's technologies and products, and the application of these techniques produced products always have people facing the risk of patent infringement claims. The South Korean government will give the country the power to support companies such as Samsung and LG easily buy the world's backlight LED chip, LED chip man-made stock or price increases.

Enterprises: involved in LED technology to the application package from upstream to the enterprise can be said that Japan, Korea, and Taiwan's large enterprises are the largest, only Japan Japan's Nichia, Toyoda Gosei, companies led by Mitsubishi Chemical mastered the art of the chip, phosphor and optical materials technology, Japanese Citizen, Sharp, South Korea's Samsung, LG and other packaging products occupy a high-end market, while Taiwan's wafer, Everlight, Kellett, Lite-On dozens of companies has become a the world's largest OEM base.

Alternative Analysis: Japan and South Korea and Taiwan have a good technical foundation to promote the application of a strong government market, LED cake eating, they will be like as a group of jackals, closely following the U.S. sub-industry profits in the pace of cutting a piece of high-end, the two third-rate products and technology thrown into the Chinese market, China wanted to rob? Estimate great difficulty.
Fourth, the Chinese mainland chain
With the current energy saving pressure, the Chinese government has already started in the year 2007 after all of the LED industry support policies and measures. Now have or will have the scale size of the upstream low-end chip manufacturers have more than thirty, and the low-end packages as the main business are concentrated in the Pearl River and Yangtze River Delta region, its production has been accounted for 60% of the world total, while the downstream end applications, is more substantial, estimated only the Shenzhen area of ​​the LED packaging and application of large and small enterprises up to nearly 3,000.
With the government policy to further mislead, exaggerate the Mainland's investment climate, coupled with large-scale state-owned enterprises, listed companies, venture capital and money-obsessed boss, LED companies are now shown a surging, waging a strong momentum, as long as you people in the little pay attention to notice the so-called establishment of national and global "best" of the photoelectric industrial park in the last two years, at least as many as 50 or, worse, even some three-four of the counties and cities have vowed to build the world's largest photovoltaic industry the park.
We can not predict five years, these so-called "largest" corporate fate, fear is the result of this herd will be littered with felled. Fierce price competition, the end will not only form a huge human, material, resources, land, waste and the outcome of agents just quickly disappeared, and the ultimate winners from a pool of blood in the blaze would be easy for the international lighting giant or international grab capital, LED industry is in the end to do for others awake in doubt.
Take the Zhongshan example: Although the experience of the international financial crisis in 2008 resulted in closure of town lighting industry trend of baptism, but because of the low-end consumer market, the domestic firm, now Zhongshan still catch on, the marketing momentum as ever. With the swing for the LED lighting industry, the town seems to have ushered in the great development of the "spring", the ambition of the local government and national institutions and organizations seminars and semiconductor alliance, hoping to build semiconductor lighting the world's wind of the LED lighting market and business gathering group.
As everyone knows, the current popular phrase in the town business called "not the best (quality), only the lowest (price)." Since the state delay the introduction of uniform standards and related products, market access and strict monitoring system, in looks like a sunrise The LED industry has not yet started, it has put the industry and made a foul, shoddy products, performance is very unstable, in the minds of consumers created a very bad impression, so do those who really want the product, insist on technology, the quality of business survival difficult.
Alternative Analysis: China's LED business as currently fought over on the grass in the desert to eat a small group of sheep, always think the grass is large enough, can eat their own how to do it, but the disorderly competition will last for how long? Fight each other after the tragic result is abortive or grow hard surrender to international lighting giant in the name of the gradual acquisition of OEM or swallowed.
We call Industry hero, longing for a "miracle", but these dreams must be built on a steadfast focus on improving product quality and personnel training, whether they go, there is no brand awareness of enterprises are not taking long-term .

Japan launched JEL 801 standard straight tube LED lights

Japan is Asia's fastest growing state LED lighting, especially after the 311 earthquake, impact by consumer awareness of energy saving, LED lighting sales grew rapidly, from April to June 2011, Japanese sales of LED lighting over the same period last year. more than 2 times, the Japanese government said in response to lack of power saving policy will continue at least until 2012, so the industry is also forecast sales of LED lighting will continue to grow.

Japan's rapidly growing sales of LED lighting, but also in promoting relevant standards is particularly important, in the LED lighting standards, the Japanese Industrial Standards Committee has developed LED light bulb-type safety and performance standards (JIS standard), and in October 2010 Japan's electricity industry will also set out the ball straight tube type LED lamp standards, content with particular emphasis on the security part.

Affect the straight tube type LED lights for the safety of the most important factor in the circuit is compatible, now part of the straight tube type LED lights use compatible with the straight tube fluorescent lamps in the mouth of gold, can be directly installed in the fluorescent lamp seat, but the circuit must be modified such as fluorescent lamp with ballast removed, or replaced the rectifier and other ballast, hence the straight tube LED lights installed in the holder on the unreconstructed, may cause smoke, fire and other hazards.

Japan's electricity industry will set the ball out of the JEL 801 straight tube type LED lamp standards, in order to avoid consumers mistakenly straight tube LED lights installed in the circuit is not compatible with a risk, the use of straight-tube fluorescent lamps with incompatible oral gold design, gold, and to strengthen port security measures, so that light can be more securely mounted on the holder, to avoid falling when earthquakes and other hazards.

Japan is Asia's fastest growing state LED lighting, LED lighting, its standard is to set the fastest in Asia, the contents of the most perfect, especially the standard straight tube type LED lights, it is significantly ahead of the rest of Asia. Currently in China, Taiwan, the manufacturing of LED lamps have many opportunities to export to Japan, JEL 801 standard will have great reference value.

Groups around the world lighting type LED lights for straight movements related to

Nine LED bulbs LED business Differences between design ideas

With the price reduction, LED light bulbs has begun to spread. Recently, not only Japanese manufacturer, Korea, China, Taiwan and European manufacturers have also started to focus on other products of LED bulbs. To this end, the East Asian region sales of 9 LED bulbs were disassembled and analyzed, found that Japanese manufacturers and foreign manufacturers in the design of thinking there is a huge difference.
LED bulbs as a substitute for incandescent bulbs growing concern. It features low power consumption, but, in addition to high prices than incandescent bulbs, many users believe that the existence of "large", "heavy" and other design issues. This is currently being sold on from a number of East Asian production base LED bulbs for the dismantling and analysis in order to find the inspiration to solve these problems. By dismantling and found that the Japanese manufacturers and foreign manufacturers the differences in design ideas, this is the "Japanese firms the importance of design, while the cost of overseas manufacturers are given priority."
\
Most clearly reflect this difference is the LED light bulb base. Overseas manufacturers of LED light bulbs are equipped with heat sink, the Japanese manufacturers have products with no heat sink. Zhayi think that there is no heat sink will be cheaper, but in fact there is no need to use heat sinks are often part of high heat resistance, so the cost is not reduced. Do not use heat sink "in order to improve product design" (Toshiba Lighting & Technology). Not just the company, many Japanese manufacturers are working hard to close the shape of the LED light bulb incandescent light bulbs. The overseas manufacturers of LED light bulbs "through the use of near-extensive design, cut costs" (dismantling of technical assistance).

Let's look specifically reflected in the appearance of different design ideas.
Shell surface temperature of different light bulbs
The total dismantling of the 9 LED bulbs, respectively, from South Korea, mainland China and Taiwan products sold in eight randomly selected, and the sale of products from Japan, choose the closest appearance of incandescent bulbs 1 (Figure 1, table 1). These products are used E26/27 ordinary light mouth. The nominal value of the product, the power consumption in the 4 ~ 7.5W range, the total flux in the 210 ~ 600lm range. Among them, close to the power consumption and total luminous flux of 7.2W Toshiba lighting technology products, South Korea's Samsung LED of 7.1W products and China's 7.5W ground on photovoltaic products as Group A, the other as the B group.
