How to estimate the general lifetime of LED lamps

Is Lumen maintenance rate the only parameter that determine the lifetime of LED lamps? Normally, LED lights are composed of dimmers, power supplies, LED modules, drive components and cooling sections. These modules are connected in series or in parallel within the lamp body. Each module has its own function and reliability. The fault of anyone of them will cause the failure of the entire lamps. Just like the short board effect, the shortest board determines the capacity of the bucket. The one with the shortest lifetime among these modules will determine the service life of the lamp, totally different with traditional incandescent lights. If we treat LED lamps as electronic products, which parts are usually the main reasons for the failure of the lamp?

Is Lumen maintenance rate the only parameter that determine the lifetime of LED lamps?

Common failures of LED lights include: unreasonable cooling section designs, over-load applications, faults of driver circuits, power supplies’ failures and bad components or compartments. Failures frequently happed on electronic appliances will also occurred on LED Panel Lights. These defects can be solved via the laboratory reliability tests for electronic appliances. Another failure is usually caused by the defect of electrical characteristics. Take LED lamps for example, defects of electrical characteristics include: the lumen maintenance rate, color temperature variations, shift of power parameter offsets, etc.. Environmental reliability tests are more accurate for these defects. Therefore, from the past experience of reliability tests for electronic products, LED lighting products should also follow the traditional environment and reliability tests designed for electronic products to verify their reliability and service life.

 

As the new-born 4th generation lighting source, LED has just been touched or used in many countries and regions all over the world. Thus, it is not easy to find a large number of fault data of them. A recent large-scale failure data happened in Ellwood City, Pennsylvania, in the eastern United States. According the statistics, among the failure records of 5400 pieces outdoor LED lighting applications currently used in Ellwood City, 59% is caused directly by faults of power supplies/drivers, 31% is caused by insufficient heat dissipation, 10% caused by bad LED components. Thus, for outdoor LED products, environmental simulation tests and service life tests are more important. Only take the lumen maintenance rate into account will bright about huge errors.

LED lighting industry enjoys high position

LED lighting industry in China is just like a raging fire starting from April 28th this year. There is a program that The Ministry of science and technology in 16 provinces, municipalities directly under the central government, the 21 city start lighting applications project, which makes LED Panel Light on the hot trend.

LED lighting industry enjoys high position

By n Lasheng’s fiery situation, LED drive power market also presents great opportunities. LED drive power is the guarantee for the development of LED industry chain, LED power quality directly restricts the LED product reliability, therefore, LED industry chain gradually improve today, LED driving power of childish is crucial. LED lighting industry will bring related industries to a fiery trend. LED driving power will enter into a new era as its heart is generally important parts.

As a kind of energy saving and environmental protection products, LED will save energy about 7 %. The project office of special investigation shows, Kuniteru Aki of electricity each year in more than 3000million degrees, not only save 1/3 percent, which is equivalent to a total investment of over 2000billion annual power output. Undoubtedly, the real energy saving and environmental protection will be accelerated LED lighting.

At this stage, the price of LED lighting equipment is much higher than many radical lighting, LED lighting products also need to heat, power and lens and other peripheral components, therefore, general lighting market in the short-term priming also has the certain difficulty. Interest is the biggest problem which may block the LED lighting LED landscape . LED road lamp is developed rapidly in the field of application. Because the price of the landscape lighting products is cheap, so it has a strong market competitiveness. At the same time, the world urbanization process of China is one of the fastest, driven by government policies, the country for high power, high brightness. Energy-saving LED lights is in extremely demand related data display. There is no doubt that the LED will also make great progress in the near future.

The 50th anniversary for led lightings invention: the great people and the great invention

50 years ago now, Nick HolonyakJr — the United States Ge Corp ( General ElectricCany, GE ) , an ordinary researchers, research produced the world’s first red LED, and opened the LED Panel Light history. Now 50 years past, LED industry really like he prophesied before that ” LED will have many different colors of light, incandescent lamp, the future will be replaced by LED”. Now, in the low carbon energy trends, LED industry has become a country competing development products. As the fourth generation light source, LED has been widely used in a variety of display and illumination field, also lies in that in people’s life to bring a new round of lighting revolution.

The 50th anniversary for led lightings invention

On the occasion of the 50 anniversary of the LED method, we cannot forget that in 50 years of development of the road, the promotion of the LED step by step towards the revolutionary breakthrough of those great scientists and their great invention.

Red led lightings inventor —Nick HolonyakJr.

The invention in 1962 of LED Nick HolonyakJr., he was only the United States manufacturers Ge Corp ( General ElectricCany, GE, also known as the singular ), just an ordinary researchers. He created the first red LED, but he also believes that the future can emit light of the other wavelength, it means that LED will have many different colors of light, future incandescent light must be replaced by LED.

Yellow light inventor —-George Craford LED

George Craford the United States famous electrical engineer, in the field of led lightings contributions made by the most prominent. In 1972, Dr. Craford invented the yellow light and red and orange light LED. His graduate and doctoral students are enrolled in the United States of America Illinois University, specializing in physics, who obtained master’s degree 1963, doctorate in 1967. After graduated, he joined Monsanto chemical company, the company is the world’s first mass production of light emitting diode ( LED ) company, his team in 1972 developed nitrogen-doped GaAsP ( GaAsP ).

The father of the OLED – Deng Qingyun

In early 1979, Dr. Deng found OLED. That’s one evening in 1979, Dr. Deng is on the way to home. He suddenly thought of something forgotten in the laboratory, then returned to the laboratory. He found in the dark with a bright thing, that the original is an experimental organic battery in the light. Thus began the research on OLED.

Global commercial light control equipment market capacity doubled within seven years

Study on the prediction of IMS, the commercial light control equipment market demand will be doubled from 2010 to 2017, the equipment shipments increased from 29600000 to 61600000. Most parts are used to connect the ballast, so it needs to have such as DALI or ZigBee connection technology.

Global commercial light control equipment market capacity doubled within seven years

Starting the maximum drive of a business building lighting control system is one of the factors of reducing energy use. Although specific rules vary with location of building, yet the building owners comply with the energy law. According to the United States Department of energy said, in a typical commercial building energy use accounted for 25.5%, so the joint intelligence LED Panel Light control system, a building owners can effectively control and reduce the system energy consumption.

According to IMS research analyst Phillip Maddocks said, ” in the commercial buildings, the implementation of the lighting control system is one of the reasons. You have to abide by the energy law, the reduction of energy consumption, especially the United States enacted the Title24 and ASHRAE method. Another driver is the United States of America with implementation of compensation to promote the installation of commercial light control system. In other regions, such as Europe, at present the same level of legislation does not exist, but the acceptance of these systems are in rising trend;

Current, in commercial buildings to install lighting control system, using a series of wired and wireless communication technology. The most outstanding is the DALI; although there are several companies to provide their proprietary version of the technology, yet they can not be mutual cooperation. However, for ballast and sensor standard is expected to be released in 2013; it will promote the use of DALI standards, so that different manufacturers of lighting control system can work together, then it will be completely different from today’s situation.

” Over the forecast period, wired technologies such as DALI still will hold the dominant position, because the majority of the company provide a reliable wireless technology, but wireless technology also have various problems and limitations. In addition, as the standard appearance of the sensor and the ballast, as well as the new DALI commercial light control system, such as control network solutions of elitedali platform, so it allows the DALI control using the platform “.

Lehman relocated labor conflict index; LED industry meet broken bubble period

Last week Shenzhen ‘s optoelectronic (hereinafter referred to as the ” Lehman” ) for emergency decided to move to Huizhou base, part of staff for separations caused compensation dispute. Insider, That Lehman was eager to move plant expansion is due to its profit situation continued to deteriorate. In fact, many LED panel light companies in order to reduce and the decline in net profit struggling. The industry is expected, the next two years will become the LED industry bubble burst period.

LED industry meet broken bubble period

Expansion of self-help lead the labor conflict

It is understood that, in 2011, Lehman fund-raising 605 million yuan (below) to establish LED Industrial Park, of which 143 million yuan for the expansion project of investment in high-brightness LED packaging devices, high-end LED display screen and LED lighting energy-saving products expansion project. The Huizhou base is the one of which raise investment project. Informed sources said, the reason why they rush to relocate due to the dual pressures of small-scale and low gross profit, and so resulted in this situation.

As one of the first landed on the GEM LED enterprises, the scale of Lehman does not outstanding. And the recent two years show that the gross profit margin declining. In the first half of this year, the company’s revenue was 148 million yuan, a year-on-year growth of 21.50%, but the gross profit margin slipped to a low point, only 13.67%. One industry analysts said, regardless of size and gross profit margin, Lehman are much lower than the peer. In this year’s market environment, the pressure to survive become greater.

LED industry will welcome the bubble burst period

In fact, in the scale and profit struggling, there are far more than the Lehman companies. In the half years, number of orders in most companies have a sharp decline. LED lighting company in Shenzhen, a foreign trade manager, said: “The first three quarters of exports fell by nearly half.” Shenzhen Semiconductor Lighting Promotion Council Deputy Secretary-General Baoen Zhong more bluntly: “This year is the worst year.”

However, in contrast with the closure of small businesses, it is a contrarian growth of some of the leading enterprises. According to Hsu Chen Shen introduced, He believes that, from last year to this year, “Mainland in a few years ago invest more foam economy, so in the the next two years it is foam centralized broken period.” Hsu Chen Shen said.

LED lighting industry and enterprises are facing four major problems(the following)

3. The price war. Chip technology improvement, raw material
overcapacity etc caused LED lighting products in LED lighting industry, price reduction that is the development trend of the industry.But there are many businesses of fish in troubled waters on the market. Shoddy,counterfeiting and other acts of “LED” under the banner of “cheap banner hanging sheep’s head to sell the dog to hurt consumers’ Heart, also caused the to unfair competition of industry. The true price war is bound to dampen consumer confidence to new thing.The lighting companies how to reshape consumer confidence, to create a cost-effective product. The highlight of lighting companies is how to carry out publicity and channel activity.

LED lighting industry and enterprises are facing four major problems(the following)

4. Quality problems.Quality and Technical Supervision in the Guangdong
Province inspect to LED lighting products sampling, inspected a total
of 23 batches about the LED Panel Light products of production self-ballasted Guangzhou, Shenzhen, Zhuhai, Foshan, Zhongshan, Huizhou, Dongguan etc 21 enterprises in the seven cities In September.17 batches failed inspection,and pass rate is less than 30%. Even some of the better-known brand products also fail. Although LED lighting has a long lifespan, good light effect. Yet it is on the base of good raw materials and seal technology only. The quality of products
manufactured by the corporate R & D technology, seal technology,
Radiating technology whether can meet the requirements described. Of course, prefer the original spending habits. Homogenization of LED lighting industry Products Inquiries lighting companies how to market segments to create a distinctive lighting products is the first rule of the lighting business innovation.

Some relative experts said, the high price is drag for LED lights in sales, but the popularity of LED lamps among is also a big reason. While the domestic market is relatively immature, so the key in competition ability of the product is from enterprise’s price, public relations ability and interpersonal relationship.

To sum up: the battle for the LED lighting industry and market has been opened, but the pain of transition, homogenization, price, quality still are the problems facing the lighting company. In the face of numerous enterprise competition, to formulate product strategy, brand positioning, and improving the technology is the enterprise core shaft.

LED lighting industry and enterprises are facing four major problems

Recently, LED lighting companies around start to be “fresh”, swept away the haze of the LED business closures due to overcapacity and other reasons.Kwok-sing Lighting first Operations Center located in Changzhou. Shenzhen Green Semiconductor Lighting Co., Ltd. Launched the first high-end LED lighting stores.Three male Aurora , co-sponsored the first domestic retail energy-efficient lighting project research,the traditional lighting companies the NVC lighting began to invest heavily in LED lighting products…Visibly under in national subsidies for local policies “booster” ,lighting companies around start to show the “Sword”. LED lighting products, channels battle pull the prelude. In the face of government and enterprises to carry out LED lighting industry in full swing, and lighting companies enter the transition of LED lighting industry and the traditional lighting companies .After experiencing a heat development, cold encounter, price surges, how to adjust their own goals and product strategic positioning, still face the inquiries of four problem.

LED lighting industry and enterprises are facing four major problems

1, the pain of traditional lighting business transformation. Face national local government  “Drastic” for promotion and  popularization LED lights.Led light “were praised”, consumers face a new thing, dare not to rush to accept the situation. “Contradictions” in advance of the traditional lighting companies, both want to seize “opportunities”, they need to rely on traditional lighting business as the support. It is an example of the traditional lighting companies NVC Lighting difficult transition, experienced senior unrest, strike of the underlying and channel division, are still in the run-in period. Although  the three executives unanimously united force in the development of LED lighting, However, the road ahead will be long ,come the bottom search . Therefore, the traditional lighting companies how to balance traditional lighting and LLED lighting industry the Road of “Shou and attack , ” how to better seize market opportunities, to play the channel edge.Looking for the LED Panel Light successful transformation is one of the  issues traditional lighting companies need to ponder.

2. LED lighting products homogenization of Shameless. LED lighting in addition to energy saving and environmental protection low carbon light efficiency and long life and goods can better achieve intelligent lighting system intelligent control, sensing dimming technology, first lamps designed light source. However, the lack of innovation in LED lighting products and traditional lighting products change, lighting design homogenization, consumers do not discern the difference between the light source and, faced with the same lighting.

The LED lighting industry in Tibet

This year is the Tibet area to carry out LED lighting industry and LED lamp promotion. The relevant departments plan to promote the use of 600000 LED lamps during the year, and use 3.5 hours of the day, day and day up to save 100000 kwh electricity, which is equivalent to compensate for the reservoir region of the 1/4 to use electric breach, it will greatly ease the tight power supply situation in Tibet area.

The LED lighting industry in Tibet

The solar energy at here is very rich, but summer power is more abundant, and it don’t need other inputs, so there are a lot of people using electricity, LED lamp  in LED lighting industry is not only for the country to carry out energy saving, but also building green environmental protection social call response and support, it is help to improve the local farming herdsman masses lighting environment and quality of life measures.

Tibet, along with the most abundant solar energy resources, ranking the forefront of geothermal and wind resource, in the development of green energy, it has the advantage to be richly endowed by nature, so it develops very fast in recent years. Combining green energy with green lighting, it will make the local sustainable development go on a harmony road. These LED lamps will further promote the Tibet area residents to eliminate high energy-consuming lighting products, and reduce carbon dioxide emissions and accelerate the pace of comprehensive protect environment.

On July, Tibet area received a peak year using electricity, daily consumption of a gap of nearly 400000 kilowatt hour. Hope green can convert to bright green, in order to save energy, reduce emissions of pollutants to Tibet, for the masses to bring energy saving and environmental protection green life.

Although people know that using ” LED ” is cheap, but should pay large sums of money to buy lamps. Lhasa city resident Yangjin said: ” those of us ordinary people and Agricultural Pastoral masses, generally can only afford a few yuan traditional lighting, other a few yuan hundreds of yuan of products, looks good, but it has the condition to use, just don’t come up with the money. ” Located in Lhasa City, Lin Kuo North Road Lighting outlets boss Liu Yincai says.

The expert points out, Tibet LED lighting industry use a vast market, mass people looks forward to research units to develop more economical and affordable products. These products are not only applied to the life, but also to the social production. It also brings convenience and efficiency, so that the LED Panel Light of Tibet resource change into economic advantage.

Global LED plant factory lighting output value of the annual growth rate

The global warming problem become more and more serious, the food shortage problem is worsening, therefore the LED lights source used in plant food cultivation, establish ” plant ” as a trend, photoelectric Association industry analysis, LED plant factory lighting year GDP growth rate reached 62%, the factory include billion LED Panel Light ( 2393-TW), the new century (3383-TW), crystal ( 2448-TW ), round (3061-TW) are cut into the different fields of plant lighting field, however, due to Taiwan agriculture development have a certain foundation, in addition, with the domestic market is small, the Taiwan plant factory development limited, so we advice toward production of high type crop, to improve plant lighting industry competitiveness.

Global LED plant factory lighting output value of the annual growth rate

Plant factory is fully enclosed, with artificial controlled illumination, temperature, humidity to cultivated crops, in addition to reduce water loss, but also through artificial LED lighting and air conditioning energy saving. Right now, Japan is actively involved in lighting factory development, according to statistics, up to the end of March 2011, the Japanese half artificial lighting factory have reached 16 department, the completely illuminated with 64 office.

Photoelectric Association industry analysis teachers pointed out, LED agriculture lighting has obvious energy saving effect, according to statistics, in the fluorescent lamp plant seedling plant, lighting energy consumption up to 82%, but if LED is used to replace traditional lighting that can reduce the energy consumption; the domestic factory lighting also enter the plant lighting applications, such as lighting in 2011, and Philips, Japan’s Mitsubishi Chemical and other international companies, LED plant lighting signed a strategic cooperation agreement to study the common development of special LED lighting application products together.

But at the minimum request of Taiwan’s domestic market, it is not good for the development of  adverse bio-tech, and in addition to increase agricultural biotechnology R & D and production management code is not perfect, and the investment of Taiwan biotechnology medical and agricultural research and development human funds is low, so it made Taiwan plant lighting market and failed to have substantially leap, Fan Huairen had a proposal that except government actively fostering, our domestic should use the original advantages plus the location of southeast of the transport hub advantages to develop usury based products, including vegetables, orchids, medicinal herbs and other products, and get into the mainland market, at the same time with semiconductor technology, and to accelerate, improve production process.

Exhibitors are not joining in for fun, led industry exhibition have more doorways

One, choose the exhibition : for enterprises, to choose the exhibition is very important, every year around the world, there are held numerous LED exhibition and all are not suitable for every LED lights enterprises, enterprises need according to the exhibition theme, character, regional consumption characteristics and visitor groups to choose the exhibition. For example, LED upstream nature of the show, LED industry downstream enterprises is not suitable for participation; and the type of foreign trade development of China’s domestic market and there is no plan LED enterprises are not suitable for participation in the Mainland Small exhibitions.

Exhibitors are not joining in for fun, led industry exhibition have more doorways

Two, select booth: Exhibition Hall location choice for participating enterprises also appears very important. First of all, the entire exhibition person flow is different, enterprise needs to choose a large flow of people; in fact, the quality of the participating enterprises booth around is also very important, if periphery is large LED industry companies, it will be attracted a large number of visitors, and it can drive around person flow, it also can be enhanced to some extent the whole image of enterprise.

Three, exhibition hall design: The design of the pavilion is a negligible factor, because it is the first impression that will attract customers came to visit, but not because the bigger, exhibition hall is,  the better, it will be. Companies need a reasonable choice of the size of the booth according to their actual situation. At the show site, many pavilions shouted in appearance, coming and going, the design of the pavilion can provide as much as possible to see the products and to give guests a comfortable visit just like the urge to go in and have a look, including the appearance of the pavilion is novel, which can provide the design of the environment; the inside design of pavilion can decide the length of time that visitors stay in the exhibition.

Four, Basic information: Exhibitor information need to prepare complete and sufficient, including sales staff business cards, product catalogs, led street light company Profile, bags, gifts and so on. The preparation of these things is not possible, for example, do the high-end market, hungry-issuance of materials is quite reasonable.
