solar powered led street light and Reliability

‘Reliability’ is a noun, a time when the spindle means that the equipment specified, limited period, the probability of the normal operation of equipment. Reliability of the concept has been applied in the electronic product design and R & D stage, its purpose is nothing more than to be able to meet the expected to the quality of their own product design and meet the needs of the users.

Of course, because between 2008 and 2009 global financial tsunami, the economic situation into a rare low tide, the ‘carbon reduction’ has become the world’s only slogans and common goal, so the LED (light emitting diode – Light- Emitting Diode) and therefore become a ‘save energy and reduce carbon’ era of the product. As long as it is involved with the ‘light’ products on the relationship between the various manufacturers had no no attempt LED lights intercropping link. Such as: lights, lighting, indoor atmosphere lights, billboard lights, lights, panel backlight … and so on, in the past two years, rapid development, and even the speed of development of these LED-related peripheral products is much larger than the international standard unit related to the development of LED testing regulations, resulting in the world, no one put universally applicable code of laws for LED related products used by the designers, the LED regulations on the market into a hundred schools of thought contend, respective interpretations of the Warring States.

solar powered led street light and Reliability

So I see this situation, and judged the results ina short period of time should not have to reach a consensus, and thus would like to provide some recommendations for the majority of the LED product designers, the objective is not to call people to the regulations of LEDs to birth, but to share their personal experience in the reliability of the field to outline that there were no precedents or international standard methods under the guidance of origin as a product designer, how LED products designed to do preliminary and basic authentication Understanding developed by the tolerance of LED products, thereby enhancing their quality of design standards to improve market acceptance, as well as reduce the risk of customer back.

The following briefly describes the two major parts, regardless of the LED is showing the way of parts or finished products, can use and follow the following pattern to achieve the basic validation of the LED products.

(1) product life verification
In the electronics industry, the requirements of the products of life, usually using the three methods

(1) life prediction method (Prediction)
Methods: The principle of the counting method (Part count) and the parts stress method (Part stress) according to MIL HDBK 217 parts, the use of software to calculate the life of the product.
Advantages: short time-consuming, low cost
Disadvantages: the results with the actual product life far different

(2) lifetime measurement method (Demonstration)
Methods: Using the acceleration model (Acceleration model), calculate the acceleration factor (Acceleration factor) and the actual sample to the use of environmental test simulator samples measured in order to achieve the life of the product. Acceleration model to the Arrhenius model (high temperature accelerated), the Coffin-Manson, model (temperature cycle acceleration) and Hallberg,-Peck, (humidity accelerate) with the highest degree.
Advantages: compared with the results of estimation used real, industry-accepted high
Disadvantages: higher cost and time-consuming than the forecast method

(3) market feedback method (Field return)
Method: the user of recycled products used in the market situation.
Advantages: the result is equal to real life
Disadvantages: time and cost of longer market the use of difficult to obtain, usually only the brand field of self-preservation
The above three methods to obtain the product life life measured up to the industry using, because it will not only exempt from the results actually produced the gap is too big drawback, and it is derived through the measured, regardless of the buyer and the seller acceptance are high.

Environmental testing verification
I have proposed in the March issue of component magazine in 2009 on the definition of environmental testing of the LED-related products need to execute projects and these projects is simple. Therefore, in this test and details not to dwell. But this should be guided how to use these environmental pilot project has reached really improve the quality standards of product design.

Must first do the analysis of the contours of a life for their design of products, the existing environment of the product life cycle may be at? User why? The properties of this product? Are there other special requirements? These factors are likely to affect the future specifications of the test, not to fall into the norms of lost in the process, verify the specifications is by no means completely from a specification completely copied into a good, because no matter how good the specification can not simulate the actual environmental needs that are only futile, it will only waste more resources and cost. For example: LED lamp designers to design a street lamp to street use in Indonesia, and verify specifications and to develop low temperature of -40 ℃, very happy to do so, as proposed in the IEC where low temperature is -40 ℃. But please recall that Indonesia is located near the equator, a tropical climate, hot and humid throughout the year, how can encounter -40 ℃ climate? Therefore, never touch the environment to do product design, will only increase the design costs because the design can withstand -40 ℃ environment LED lamps cost is higher than the design enough to withstand the environment of 0 ℃.

The difficulty of solar powered led street light is in industrialization

The difficulty of solar powered led street light is in industrialization

Samsung is not only technically a monopoly, materials, equipment, build their own industrial chain. It OLED production equipment to buy up as soon as the South Korean companies apart the to imitate, solar powered led street light, next to a new production line to turn in Korean equipment.
Guangdong four years ago, the layout of the OLED industry, was invited to known as the OLED Chinese Three Musketeers “one of technical experts to guide. Because Kodak invented the OLED is ethnic Chinese.
“It is difficult industrialization.” To a domestic enterprise who sighed and said: OLED industrialization in Japan did not do. The Chinese have an important contribution in OLED development, solar powered led street light, but the “Three Musketeers” would not contribute significantly to the industrialization.
“OLED industrialization than the PDP, the LCD is much more difficult, many devices to be customized requirements higher than the LCD device; plant higher precision; materials and products are linked closely together, such as Samsung AMOLED IC (chip), led high bay even if purchased and also need to one-to-one correspondence in order to use, OLED manufacturing a lot of the know-how. ”
The laboratories of many universities in China can make OLED. An industry source disclosed that the problem is the ability to do high quality, solar powered led street light, do successful one of 100 or 99. Samsung AMOLED high resolution, there are many patents in the production process.
Above show business people, the OLED industry of the three major obstacles: First, is difficult to find experts with production experience, Samsung very strict control; equipment, Samsung holding a lot of Korean equipment factory in China to purchase equipment and limited; material lies in the hands of the Americans, the exclusive supplier to Samsung.
“Pre-encounter great difficulties, spent two years and only then things to implement, solar powered led street light, vthere is a material ran Japan fifty-six trip to get it.”

Ahmadinejad is laughing solar powered led street light on the question

Ahmadinejad is laughing solar powered led street light on the question

 

Iranian President by the question 33 years the first time

Mr Ahmadinejad ridiculed the solar powered led street light problem is too simple

Iranian parliament on the 14th question President Mahmoud Ahmadinejad – Ahmadinejad, asking him on economic policy issues to answer. Parliament question the president, in Iran, 33 years ago the first time. In the meantime, Ahmadinejad – Ahmadinejad from time to time verbal banter, which angered members.

“Do not want to.”

Iran 79 Members in February launched a motion requesting the question to Ahmadinejad – Ahmadinejad. President arrived on the 14th Parliament, to more than 200 members, admits: “We do not want to.”

However, he promised, will play the role of “good student” to listen to Members’ questions and answer each solar powered led street light .

When the Conservative MP Ali muta Harry read time exceeded the 15 minutes, Ahmadinejad – Ahmadinejad said, he asked for the timeout to answer questions. The problems include the lack of government funding to the Tehran subway project, failed to achieve 2011 economic growth target of 8%, high inflation and the Iranian currency devaluation.

“Not guilty”

Another focus of the question Ahmadinejad – Ahmadinejad Iran’s supreme leader Ayatollah Ali al-Husseini Benny Ali Khamenei “disrespectful”.

April last year, Ahmadinejad – Ahmadinejad accepted the resignation of Intelligence Minister Heydar Moose Lee, and Ayatollah Ali Khamenei refused to ratify the Moose Lee is able to remain in office. Later, Ahmadinejad – Ahmadinejad twice absent within led high bay

Club weekly meeting days but asked the government affairs to express their discontent.Open conflict between the president and supreme leader.

Conservative MP muta Harry read the question: “Do you have any reason to 11 days (absent) to resist the commands of the supreme leader?” Ahmadinejad – Ahmadinejad replied, he did not challenge the authority of Ayatollah Ali Khamenei. “The situation is such, Mahmoud Ahmadinejad – home to rest some of my friends always advised me to rest, and this government has never stopped one day.”

“Stability score.”

The same day question by Iranian radio broadcast, the content is not involved in Iran’s nuclear program and in response to Western sanctions. In the meantime, Ahmadinejad – Ahmadinejad from time to time by opening joke, Members are quite dissatisfied with.

Ahmadinejad – Ahmadinejad claimed that the Honourable Member’s question is not difficult to answer. “The problem for me is like holding a master’s degree and racking our brains can come up with the answer if you ask my thoughts, there may be better.” He put the question than for school exams that this exam if they can not get high marks, solar powered led street light that Parliament is really little more than “rude”.

These words angered a number of Members. Mr Mustafa Husseini said: “using insulting words in the entire speech, President. Him evade the issue, does not give us any logical answer to this point, as we expected.”

Harbin: how far solar powered led street light away from us?

 

Consumer Ms. Wang: I know that LED products are good products, good idea is not clear, but in the process of purchases shopping guide said LED products, they will pay attention, but also to see the price is not able to accept, if theyThe budget can accept, they will accept and select. The publicity of the sales staff is critical. They already contact with the ordinary consumption of LED products, LED light flashlight, home early led high bay lamp cup, LED computer monitors mentioned wanted to use solar powered led street light, just worry about their own can not buy good price products.

 

The enterprises lighting Mr.Tang: targeting high-end enterprise, one LED spotlight products, a one-watt spotlights more than 100 yuan, 3 watts to more than 200 yuan. All of which are used in the United States Corey chip, so the cost is also high. But great selling point, pro-gaze, easy to win in the high-end consumer groups and corporate planning objectives of the Decade products, so that the dealer is very sense of belonging, but because the price is more expensive, so rarely used in engineering, the cost is too high, the only star hotels.

 

Zhang Xin Wang Lighting: Main solar powered led street light, the category involved in lighting, home category, LED guardrail tube lighting project in the application, the Government’s street festival lighting has used street lighting in a large number of high-power LED as light source, including the lighting of the courtyard, as long as the government to do the engineering will be preferred LED products, and more upset because of cost issues, and now a lot of companies are doing solar LED products.

5 good family use solar powered led street light

From 1950, China has a special new world “5 good family”.

As we all konw, as a new 5 good family, one of the most the important thing is energy saving. Now, one of the most important thing is using solar powered led street light. As we all know, solar powered led street light is one of the best LED Lighting Products application, because all the solar products use only the energy from the Sun. So, if we want to be a 5 good family, let’s use solar powered led street light.

The “five-good civilized family” activities are carried out in all households in the country to change our habits to the “patriotic law-abiding, public-spirited good; to learn and progress, good dedication; equality between men and women, care for the young;, fewer and healthier fertility; thrifty and protect the environment “created for the content of the civilized family activities. Originated in the 1950s, the linkage of a family construction work up and down the China Women’s Federation. In 1982, the China Women’s Federation sponsored the activities of “striving for five-good families”. In 1984, Shanghai will first “five-good families” activities into the overall planning of the construction of spiritual civilization. In 1985, cities across the country, “five-good families” activities into the planning of the respective spiritual civilization construction. Was the standard of five-good families: the political and ideological production work; family harmony, respect the elderly; education of their children, family planning; change our habits, frugal; neighborhood unity, polite.

The spirit of 1996 to implement the implement the Party’s Sixth Plenary Session of the 14th CPC Central Committee resolution on the strengthening of a number of important issues in the construction of socialist spiritual civilization “, and vigorously promote care for the young, gender equality, harmony of couples, frugal, neighborhood solidarity The family virtues, China Women’s Federation in the activities of the “five-good families” was renamed as the “five-good civilized family activities. In November 1996, United Central Propaganda Department, Ministry of Civil Affairs, Radio and Television Department, State Education Commission, Ministry of Public Security, Ministry of Justice, Ministry of Culture, Ministry of Health, State Family Planning Commission, the National Sports Commission, the State Environmental Protection Administration, People’s Liberation Army General Political Department, the straight Organs, the Central Government Organs, National Federation of Trade Unions, Communist Youth League Central Committee, China Association for Science and Technology 18 ministries issued on the continued implementation of the “five-good civilized family” activities to create a joint notice, clearly the guiding ideology of the activities to create job requirements, named in recognition of management practices, and also made new provisions for the five-good civilized family selection criteria developed by the China Women’s Federation in 1982, “five-good” condition, namely: the patriotic law-abiding, public-spirited good; learning spirit, love Kong dedicated; equality between men and women care for the young; refinement to have fewer gifted education; frugal, protect the environment. That same year, Beijing has set up activities to create a coordinated leadership team around the following content to create activities carried out jointly by the “five-good civilized family” in both urban and rural areas. To improve the ideological, moral, scientific and cultural qualities of the family members, vigorously promote the virtues of family. To carry out a variety of family and cultural activities, and advocate healthy and civilized scientific way of life. Play a positive role of family in maintaining social stability and promote social stability and to the civilization of the family. Around the party and the Government was concerned about the social hot spots and difficult problems in the family volunteers contributing to others, and contributing to society. The highly publicized recognition of five-good civilized family and advanced family advocate family of fresh air. In recent years, focusing on family devotion, family culture, family environment, family education and family life changes constantly deepen the “five-good civilized family” to create activities. The “five-good civilized family” to create activities for improving the quality of family members to improve the family level of civilization played an active role to promote a civilized city, civilized towns and the creation of civilized industry.
