Parsing LED reliability validation methods and necessity
The following briefly describes two parts , whether led to parts or finished products presented , can take advantage of and follow patterns to achieve basic authentication led outdoor lighting wholesale products.
1 product life verification
In the electronics industry , in order to obtain the product requirements of life, often using three methods
( 1 ) life prediction method (Prediction)
Methods: According to the principle of MIL HDBK 217 parts count method (Part count) and Parts Stress Method (Part stress) , the use of the software to calculate the life of the product .
Advantages: Short time-consuming , low cost
Disadvantages : The result is easy and practical differences in product life far
( 2 ) Measured Life Act (Demonstration)
Methods: acceleration model (AccELeration model), calculated acceleration factor (Acceleration factor) and provide real samples using environmental testing simulator measured the samples in order to achieve product life. Currently Arrhenius acceleration model to model ( high temperature accelerated ), Coffin-Manson model ( temperature cycle acceleration ) and Hallberg-Peck ( humidity acceleration ) with the highest degree .
Pros: The results compared with the estimated true law , the industry accepted high
Disadvantages: high cost and time-consuming method than the estimated length
( 3 ) market feedback Act (Field return)
Methods: The recovery of the product user position on the market use.
Pros: the result is equal real life
Disadvantages: time and cost more , the market situation is difficult to obtain using usually only brand of self-preservation field
These three methods to obtain the product life of up to life measurement method adopted by the industry because it eliminates not only produce results and the actual gap is too big drawbacks , and it is obtained through the measurement , regardless of the buyer and seller to accept a high degree of both .
2 environmental testing to verify
First, we must do for their own products designed to analyze a contour of life , in the life cycle of the product that may be stored at ambient ? Users Why ? Properties of this product ? Product without other special requirements ? These factors are likely to affect the future is the standard test , in the process not to fall into the norms of lost , because a good validation specification is definitely not completely copied into outright from a specification , because even the best can not simulate the actual environmental norms demand , that are just vain , only waste more resources and costs. For example : LED lighting designers to design a street lamp to street use in Indonesia , and to develop a low temperature -40 ℃ to verify specifications , and very happy to do so , because the IEC in the proposed low temperature is -40 ℃. But please recall that Indonesia is located near the equator , has a tropical climate, hot and humid all year round , how come the climate -40 ℃ ? Never touched, so the environment to do a product design , will only increase the design cost , because the cost of the design can withstand -40 ℃ ambient LED lighting must be designed to withstand the environment is higher than 0 ℃ 's .
It is a product designer should please return to fundamentals , a good view of their own designed products in order to achieve an efficiency can meet reliability verify the actual demand side .
Finally , because the led outdoor lighting wholesale is different from other electronic products, before and after the verification must be done regardless of the reliability of measurement for their luminescent properties , commonly used calculus curve balls or light meter, to measure the color of LED products (Color temperature), the flux (Luminous flux), light intensity (Luminous intensity), color coordinates (Chromaticity coordinates), CRI (Color rendering), wavelength (Wave length) , etc. , in order to verify the reliability as a basis for judging the results .

Let led lighting fixture products approach to ordinary people
Although the phase-out of incandescent roadmap already very clear , and many countries have also released to encourage local production and related support policies to promote LED products , but due to the price factor , LED lighting from ordinary people really can accept , there is still a certain distance.
Some people say , Home LED indoor lighting is based on the growth of sapphire . That is because the first choice for the production of LED chip crystal material - sapphire , accounting for all the LED manufacture with 85% of the substrate material. In general , the cost of LED products accounted for up to two percent of the sapphire substrate can be said that the maximum LED supply chain cost materials . It can be seen , if you can find a cheap thing more beautiful materials to replace the sapphire LED to reduce the cost of production , it can eventually really into homes of ordinary people , and its role is obvious. Li Guoqiang and his State Key Laboratory of Luminescence Materials and Devices , South China University of Technology LED epitaxial materials and device research team is doing it . "If a lot of people because of our research and lead healthier lives convenient , it would be great as researchers ( blog , Twitter ) honor ." Make life-changing technology , is the largest wish him and his team .
This year 35 -year-old Li Guoqiang , a professor of South China University of Technology, doctoral tutor , 2013 Annual Guangdong Natural Science Fund for Distinguished Young winner . Mainly engaged in III-V compound semiconductor materials and devices , and presided over a number of national , provincial and ministerial level scientific research projects. In recent years, the internationally renowned journal published 68 SCI papers ( ESI highly cited papers in which an impact factor IF> 9 Article 2 ; IF> 4 cover article 4 ; and IF> 3 Article 20 ) . Papers cited 551 times , including three times by the Science references cited more than 20 times the U.S. and the Chinese Academy of Sciences / Engineering Academy . 45 patents , authorized 20 ; 10 times for special reports at international conferences , 30 oral reports ; Director of International General Meeting / Chapter President twice. In April last year , Li Guoqiang was awarded the fifteenth session of the " Guangdong Youth May 4th Medal ."
Over the years, Roger Lee and his team have made great achievements in research on alternative use of new materials in sapphire . They will be different epitaxial growth of new substrate materials for III -nitride film , based on the new substrate to promote the blue-white LED technology ; microscopic structure of defects and defect III-V compound semiconductor formation mechanism , improve the quality LED epitaxial silicon material ; proposed a patterned substrate design ideas , and so the development of related software to design a variety of new graphics substrate solution greatly improves the efficiency of LED light . Related research cooperation with domestic LED industry leaders , produced good economic returns.
Their findings have been published in internationally renowned academic institutions of the Royal Society of Chemistry (RSC) is highly recognized . RSC journals such as the Journal of materials and chemical industry has a significant influence of Materials Chemistry C (SCI a district magazine , IF = 6.1), in the form of February 7, 2014 issue of the first five on the back cover of the article, published in the team when the results of a study , with some eye-catching text, the results of such research and evaluation team : " Professor Li Guoqiang team led by State Key Laboratory of Optoelectronic semiconductor light-emitting materials and devices belonging to the South China University of Technology , is driving the new compound semiconductor materials and development " of the device.
The team another report prepared by the blue LED on the new research patterned substrate , crystal growth were authoritative journal , the American Chemical Society (ACS) of Crystal Growth & Design (IF = 4.7) 6 June 2012 as article 6 issue of the cover article published . Then, in the semiconductor industry and academia has a strong influence and status of the internationally renowned magazine "Semiconductor Today", and in its representation of the results in September 2013 in order to "Optimizing spherical cap patterned sapphire for nitride semiconductor LEDs" for the questions, with two special reports devoted a team to work in the new graphical design and Home LED indoor lighting production aspects of the device that LED on the patterned substrate of spherical thesis " proposed for improving nitride LED light extraction efficiency has great significance . " And commented that , due to the " new pattern patterned substrate height is low, so the short pattern processing time , helping reduce processing time and costs, which has great significance for LED large-scale industrial production ."
Prior to 2010, returned to work in South China University of Technology , Department of Materials Guoqiang is a Royal Society Research Fellow at Oxford University , Institute of Industrial Science , University of Tokyo foreigners JSPS Fellow , General Electric Global Research Center senior research scientist. At that time , the famous British manufacturer of LED and optoelectronic components Oclaro provided him with an indefinite contract and permanent competitive salary ; Meanwhile, the University of Cambridge also dished out an olive branch , hoping that he can join the school's LED research team . However , Li Guoqiang has abandoned the British favorable research conditions and jobs, and many outstanding students studying the same country , with the dream of returning to China to serve the country and return to Guangdong . He said : "Science is the service of human progress should be independent of fame , I want to do something for my country before choosing returning ."

Strategies Unlimited: Watching LED lighting market clearly
Global lighting market is a smooth transition to LED technology. Recently , Power Integrations and Strategies Unlimited analyst Katya Evstratyeva ( Her research involves the application of general lighting LED replacement lamps ) were met , depth discussion of this important technology in the process of changing some of the basic trend , and some general the interpretation of misconceptions .
Whether adopting fairly consistent worldwide LED commercial lighting Manufacturer technology ?
No, it caused some misunderstanding. LED lighting technology adoption varies depending on the application , very different , in addition, the planning and development of each region are different. When talking about the growth of LED technology , understanding the precise definition of the area to determine an application referred to and is very important. For example , although the high cost of LED technology, but adoption rates in Japan in terms of replacement lamps to be ahead of any other country in the world . As a result, Japan's high adoption rate advantage will likely remain for several years , while in North America , with the lower cost of LED technology , the adoption rate began to significantly increase . Therefore, you can not apply the same rate to apply from one application to another application or market or markets. Regional factors and product factors are important factors that must be considered .
LED lighting cost trend driven by what factors ?
This problem is easily misunderstood , because there are many factors at play. When we consider the BOM cost of replacement lamps , LED itself, we have accounted for an estimated 40% to 60 % of costs in all areas , depending on the application . Although the U.S. Department of Energy (DoE) has drawn up a roadmap for the industry , which is expected to cost the LED will continue to reduce , and the cost of other important components ( such as drives ) will also be gradually reduced, but there are still many factors that play a role in . Manufacturers must be operating costs, labor costs and research and development costs included. And retail sectors increase in applications between different countries and have a very big difference. Traditional lighting sales channels rather complex , intermediate generally involves three to six middlemen, brokers have each accounted for a certain proportion of the increase . Thus , not only consider manufacturing costs , but to consider the impact of the final sales price of the entire system .
Relative to the rapid increase in the prior art , if the current price of LED lighting LED technology adoption rates would hinder ?
If we say that the price is to promote people to buy LED bulbs only consideration , and this is wrong. In some markets ( such as North America ) , consumers are more concerned about the price , while in other markets ( such as Europe ) , the buyers are willing to spend more money , because they are more concerned about the quality of the lighting of the lamp. Japanese consumers are even willing to buy LED lights , LED lights because they will be seen as a reflective and implement energy-saving electronic devices . For manufacturers, the main challenge is to accurately grasp the specific needs and concerns of their customers.
Consumers decide to buy LED lights in the process, an important factor in how high degree of energy efficiency ?
Although the ROI calculation is often described as a very simple thing, but it may become a more complex issue. In addition, the value proposition for each region and each application are different. In Europe, the average price is between 27-30 cents / kilowatt-hour (kWh), while in the United States , the national average price of 12 cents ( but in California , the average price up to 24 cents ) . According to DoE statistics , residential bulbs average use of 3 hours per day. While most consumers say they are interested in a more efficient LED commercial lighting Manufacturer products , but they have to be allocated to the ROI many years to recover , they will find it more difficult to justify the initial investment is cost-effective.
ROI calculation more attractive in commercial and industrial applications, because the company has saved more comprehensive cost records , usually at a higher price to pay , and the light bulbs and lighting equipment working hours per day between 10-11 hours . In addition, maintenance costs warehouses and large buildings may involve special equipment and produce high costs . Eventually, the plant manager had to consider the bottom line of each application .
In the LED commercial lighting Manufacturer industry, whether there have been improvements in the field of ripe ?
We see the whole field of lighting control is becoming increasingly important. But this time the situation was very complicated , because we have no common definition. Currently , each company typically provides its own control systems and lighting equipment. Some large manufacturers through its own efforts to achieve greater energy efficiency introduced solutions . We think this is an important area for further development of the lighting industry will grow , but at the moment, we can only see different companies doing their scattered efforts.
