The household led light bulbs is required to shuffle the card

 

The household led light bulbs is required to shuffle the card

 

In the LED industry, many people in the Scream LED industry will reshuffle. Shuffling personal opinion is not the most important issue, the question is what the problem is caused by the shuffle.

 

Shenzhen is the country’s largest LED display manufacturing and supply base, LED backlight, household led light bulbs are the world’s largest production and supply base. About 3200 LED enterprises account for 40 percent of the country. Many people believe that enterprises in Shenzhen this year will be reduced by 20% -30% means that nearly a thousand LED business in the economic winter “dead” to go. More pessimistic predictions, currently nearly 8000 LED Enterprises “when the reshuffle of the industry as a whole, the country remaining 300 enterprises would be sufficient.”

 

Higher elimination rate of the household led light bulbs industry, entering large state-owned enterprises, small enterprises due to the competitive relationship in the exit. LED enterprises in Shenzhen this year will be reduced, means that nearly a thousand LED business in the economic winter “dead” to.

 

Although pessimistic about the development of the industry, but only the appropriate market enterprises to survive, the enterprise market-oriented. Excessive development of led high bay lighting industry, there are a lot of problems, shuffling to the unqualified enterprises eliminated, in order to allow the market to better health. More conducive to long-term development of the LED industry, but only 300 would be too cruel results.

 

Chinese government call on an Industrialization restructuring of household led light bulbs industry. There is no other choice, after China’s accession to the WTO2006, many industries needs with the international practice, including LED lighting industry.

 

Three reasons for the continuous slump in RGB led downlight market

 

Three reasons for the continuous slump in RGB led downlight market

 

The reason to come to this prediction can be summarized as the following three points:

1: the shortage of domestic talent, the country’s strong support as a sunrise industry, LED industry, the domestic enterprises herd redundant construction, not only talent ‘poaching’ phenomenon prominent; some accumulation of capital to make RGB led downlight after a sale to influence the market; more the enterprise is purely to defraud the government holding the LED of the first support funds. ”

2: The threshold is too low, many companies do bad RGB led downlight market is definitely good for the industry, the introduction of relevant policies, but did not implement. Local government if you do not examine whether the LED business is truly master the core technology, or the existence of idle land, capital, equipment, too many enterprises to enter the industry can only do bad market! The access threshold of the government audit LED business to improve, and to moderately reduce the tax burden on the LED business. As for the funding of government subsidies, the current situation is no standard no rules, loosely organized, no one to guide the development of routes allow enterprises to fend for themselves, but the government capital subsidy standards should be re-enacted.

3 exports: in the context of the European debt crisis, this year’s overseas economic environment is not good, while exports of the main exit of the Shenzhen led high bay products. In the early years, the export of Shenzhen LED products mainly exported to up to 80% to 90%; this ratio data declined only modestly from the previous year, is currently about 80%. The poor economic environment, the export of LED products have certainly been affected, and appreciation of the yuan, also greatly reduced the profit margins of these LED business.

HV technology used in solar led street lamp

 

HV technology used in solar led street lamp

 

The HV the solar led street lamp is made ​​directly on silicon chip production system on a chip (SOPs), which is a revolutionary advancement of the LED chip manufacturing technology. A 2-inch silicon wafers, one can produce tens of thousands of LED die, but using common technologies and processes to produce discrete LED parameters. So, after the production, manufacturers need to individually measure the parameter file, the client can only take the third gear of the adjacent units (light) in order to ensure consistency of display light color. The HV LEDs in the production of a new generation of technology and superb processing technology, tens of thousands of LED die in the same silicon wafers on the parameters exactly the same so easily in chip production, the nearest composition of the SOC HV LEDs for such as the 16 LEDs on the HV45, all of their electrical parameters are exactly the same. HV LEDs for easy to use, cost control. Otherwise a COB HV LED is the adoption of the aforementioned general-purpose technology to produce the parameters of discrete led high bay chips die, will be the same configuration of the test data together, re-combined into a light body. Due to the need to individually test, matching, filtering, and combinations, there are many parameters can not be dispersed paired combination use, production costs will be high.

 

In addition to the low-voltage solar led street lamp driver chip, the domestic high-voltage LED driver chip has also emerged market, the high-voltage LED chipset high-voltage, low current, compared with the common low-voltage LED low voltage, high current working environment, when the fever HVLEDs work reduce the; HVLEDs only need a high-voltage constant-current source can be a good, high-voltage constant-current power transformer, electrolytic capacitor low-voltage LED driver power supply and electrolytic capacitor life.

How to increase the duration of high-power LED driver

 

How to increase the duration of high-power LED driver

 

Essential as power devices, electrolytic capacitors must be able to long-term work in high temperature environment, this test is very grim. General-purpose aluminum electrolytic capacitor life span of only 4000 hours to 5000 hours, half life, and at high temperatures is far from meeting the requirements of the long life of LED lighting, and thus the aluminum electrolytic capacitor has become the bottleneck of the high-power LED driver. The structural design of aluminum electrolytic capacitors, the advanced nature of the manufacturing process to determine its service life. Aluminum electrolytic capacitors for LED lighting special emphasis on long life, high temperature and small.

 

The high-voltage driver chip may be one of the better solution HVLEDs constant current drive power. Some chips are ideal, but is too expensive to buy in China, used to produce general-purpose high-power LED driver costs are high. In recent years, China’s domestic integrated circuit design level rising, but there is a very good price and market competitiveness, to downstream manufacturers for the production of technical solutions and technical support in place.

 

In addition, the LED light source lamp bead is a major breakthrough. The rising star of the LED family of high-voltage LEDs (HV LEDs) have sprung up everywhere, the VF high voltage, the IF current working conditions completely subverts the traditional low-voltage (LV LED) LED VF low voltage, the IF current requirements. Led high bay lighting due to the HV LEDs SOP may reduce the shape of the heating, lighting structure may tend to be more to save cooling materials, greater than 270 degrees light-emitting, low-cost, light weight.

Obama talk about solar energy motorcycle led lighting in the United States “trade war”

Obama talk about solar energy motorcycle led lighting in the United States "trade war"

China news agency, Washington, March 21 (Reporter Wu Qingcai) – The U.S. Department of Commerce preliminary ruling on the Chinese exports to the U.S. solar panels impose punitive tariffs on one day after U.S. President Barack Obama 21 “coincidence” to access the mature within the State of Delaware a solar energy company and talked about this trade remedy cases, the U.S. is to strengthen trade enforcement to motorcycle led lighting ensure that the solar company he called the countries like China do not give them an unfair advantage.
“In fact, yesterday our administrative department has ruled that Chinese solar energy enterprises to give unfair subsidies, so we have taken the first step in ensuring fair competition,” Obama said.
The development of clean energy is an important policy of the Obama administration is pushing, he has repeatedly claimed that: “do not want to see wind turbines, solar panels and high-tech batteries from other countries, workers in production by  led high bay other countries and I hope these products America’s own production. ”
At present, the United States a total of 5600 a number of solar companies, these companies the production of solar electricity is enough for 73 million U.S. household electricity. However, a considerable number of these companies are small businesses, they are facing strong competition of the United States of cheap “Chinese counterparts.
Several U.S. solar product manufacturers had to sue their Chinese counterparts unfair government subsidies in the United States to sell their products below cost. In this regard, the U.S. Commerce Department on the 20th made the preliminary ruling, declared motorcycle led lighting to the Chinese-made solar panels, plus a levy of 2.9% to 4.73% of the tariff.
On the second day of the award made in the U.S. Department of Commerce, Obama traveled to the solar energy company to inspect, and quite a move to please the United States too can companies and their workers suspected. In response, White House spokesman Carney responded that the same day a press conference only a short period of a day is difficult to assess the effect of this ruling and the market reaction.
Recently, the Obama administration frequently waving trade with China a big stick, only in China on the 20th day to make an affirmative determination of the four trade remedy cases, in addition to solar panels, but also involving Chinese exports to the U.S. chemical brighteners galvanized steel wire, silicon metal products.
Analysts believe that the 2012 U.S. presidential election approaching, the Obama administration one hand, this is in response to the Republican “policy toward China was too weak criticism, on the other hand is to please some voters, fish for votes.
In this regard, the Chinese government motorcycle led lighting  has repeatedly criticized this with trade protectionist measures, the United States to jointly safeguard the freedom, open and fair international trading environment, a more rational approach to properly handle trade frictions.

Passing in 1962, US-Soviet mr16 light fittings nuclear war

Passing in 1962, US-Soviet mr16 light fittings nuclear war

The U.S. and the USSR in the October 1962 missile crisis is a “tit for tat”. The first secretary of the Communist Party of the Soviet Union, Nikita Sergeyevich Khrushchev, Chairman of the Council of Ministers trying to missiles secretly shipped to Cuba. U.S. spy plane over the Caribbean Islands, discovered Soviet missile deployment in Cuba, Khrushchev’s plan for the United States perceived. This article is excerpted from the heart of the dispute “(East China Normal University Press publication, mr16 light fittings  of: [U.S.] Melvin P. Leffler).

Nick October 22, 1962, U.S. President John F. Kennedy said in an emotional televised speech, the behavior of the Kremlin to station missiles in Cuba is a “premeditated and provocative in nature, is in a test of the American people courage and determination. ”  led high bay Kennedy announced that the U.S. will have implemented a comprehensive blockade on Cuba in order to prevent offensive military equipment to Cuba. If the Soviet ships are forced forward, and the missile did not remove the United States will stop their advance.President Kennedy declared: “I have ordered the army to prepare for any emergencies that may occur.”

October 24, the U.S. Joint Chiefs of Staff ordered the Air Force strategic forces into the war before the highest state of combat readiness. U.S. military officials also do ready to launch intercontinental ballistic missiles and submarine missiles. All available missile in the U.S. arsenal have been in a state of combat readiness. Part of missiles loaded with nuclear warheads, pre-set targets, airborne, sustained flight in the air, the fighters will air tanker refueling. A full week, the whole world at the brink of war, the Soviet ambassador to the U.S. Anatoly Dobrynin afterwards wrote, “our two countries are in a state of tension among a suffers.”

This tension is also reflected mr16 light fittings in the thinking and correspondence among the heads of the two. October 26, Khrushchev wrote in a letter to Kennedy: “I think, Mr. President, you can not help but also the fate of the world there a trace of worry?” Khrushchev using intermittent threats and reckless hasty decision to cover up his own inner fears, but in fact he is afraid.

Khrushchev in disgrace under the premise to resolve the crisis. “We can not succumb to emotional narcissism and cramped,” he wrote in a letter to Kennedy, the Soviet Union does not want war, “I am I participated in two world wars,” he reminded President Kennedy said, the war will only bring death and destruction, and these he will always keep in mind not easily forgotten. “Only the mentally ill and suicide” will launch an offensive war.Instead, he proposed a program in resolving the crisis. He had the idea to submit to all members of the Presidium of the Supreme Soviet of the Standing Committee to follow his leadership. October 25, the Presidium of the Supreme Soviet agreed that the crisis should not be moving in a “boiling point” development. The political game of this great country had to keep playing, “but you can not lose your head in this game. Both sides should take a cautious and restrained attitude to find a sensible solution to the crisis.Khrushchev to the Soviet withdrawal of missiles from Cuba for a bargaining chip in exchange for the withdrawal of Jupiter missiles from bases in Turkey, the United States.

But the next morning, the meeting of the Presidium of the Supreme Soviet, Khrushchev added: “We were  mr16 light fittings warned that war may be started today will,” he told the Standing Committee of the colleagues, yesterday suggested that the letter should be made modify; proposal should be deleted from the original hope that the U.S. withdrawal of missiles deployed in Turkey. We must concentrate on to consider the main focus, he said. If the Americans to guarantee not to invade Cuba, we will withdraw the missiles in Cuba.”Otherwise, the situation will become very dangerous.”
