The development of the LED epitaxial silicon using in SMD high power led

 

The rapid development of LED lighting LED products have developed rapidly, the development of its LED lights and LED Silicone is a very good performance, very bright LED lighting market development scenarios in the present, believe that people’s understanding of LED lighting that LED epitaxial the chip is an important parameter affecting the SMD high power led products, so the Shenzhen LED silicone think the LED epitaxial silicon market trends is very broad.

 

LED epitaxial growth and chip manufacturing process will directly affect the performance and quality of the terminal of LED products, is the most central part of the LED production process, its level of technological development directly determine the penetration and coverage of the downstream applications. LED technology development experience from monochrome to full color, from general light to highlight, from low light efficiency to rise in the path of the high light efficiency, and the constant improvement of SMD high power led performance to promote its ongoing in-depth to the areas of application. LED epitaxial growth and chip manufacturing sector with high technological content in the LED industry chain, the intensity of investment in equipment, while the margins are relatively high, is typical of capital, technology-intensive industries, the technology and level of development of the national SMD high power led industry structure and each company’s market position plays a decisive impact.

 

Domestic LED lighting market, even on the global also occupy a certain position, the visible LED market open, but the LED business itself a lot of problems lead to universal coverage is still not standard, I believe, with the shuffling of the domestic led high bay business there is improvement in technology, LED lighting era will soon come.

The development of LED household lighting power suppliers

 

With the rapid infiltration of the field of LED household lighting, LED market conditions are very clear, low LED market review in 2011, obviously a lot of people about to go into hibernation for the LED market is expected to errors, with the new year national increase support and promotion of the LED industry, the development of the LED is in a period of rapid development.

 

The global LED lighting power supply market is about the influx of $ 10 billion in business opportunities. Market institutions IMS research report, regulations and electricity are steadily rising drive the LED lighting market is the rapid rise is expected to drive sales of power supply to reach four billion units by 2016, with a total of up to 100 billion U.S. dollars.

 

IMS senior market analyst Ryan Sanderson replace residential use from low-power LEDs light source and light bulbs, application requirements, a variety of LED lighting solutions to commercial and industrial use of high power LED full set of lighting such as street lights are rapid increase in led high bay lighting.

 

The beginning of the development of the LED light source and lighting market, manufacturers face challenges in power electronics technical expertise, and thus open the doors of opportunity for power supply manufacturers. Sanderson pointed out that the new LED lighting power requirements, depending on the design factor of the power ratings, the LED or the number of LED string lights and use environment. These design requirements, plus LED lighting is currently no clear standards, LED household lighting manufacturers need to hire professionals or power supply manufacturers, to strengthen the power electronics professional and technical.

 

The new center of gravity of the led high hat lighting market

The new center of gravity of the led high hat lighting market

LED lighting as LED industry downstream applications part of the future, with thedevelopment of LED lighting industry and the market, LED lighting products, part of the industrial scale will be far greater than the scale of the LED in the upstream industry. “He believes that views on the industry should be gradually changed, not the semiconductor lighting as the application of part of the LED industry, led high hat lighting, but rather to look at the LED light source (chip, package, module) as the upstream part of the lighting industry after thesemiconductor lighting trends will be semiconductor returned to the re-lighting.
“At present, led high hat lighting, the size of the LED lighting industry has not yet achieve the desired one of the reasons is due to price high to lead to commercial and residential interior lighting inthe domestic market has not yet started, large-scale production of these productsmanufacturers in the export, but LED lighting products directly to consumers, the marketsensitivity of a high center of gravity of business sales will be adjusted according to market conditions quickly. ”
Last year, in order to address the high price of LED products predicament, the ground on the optical formed by virtue of mass production at the strong bargaining power, led high hat lighting, to promote the product in raw material prices reduced by 20% to 30%, a 50% decline inoverall product cost. There is no doubt that this will increase the ground on photovoltaicright to speak in the price of LED products.
Since then, another one LED lighting companies Huizhou Light Engine Co., Ltd. inJanuary of this year, the project settled in Huizhou, Guangdong Zhongkai High-tech Zone,covers an area of ​​130,000 square meters, invested about 300 million yuan. It is reported that the project in May this year to commence in the first half of 2012, After the completion of the annual value of 20 billion yuan, led high hat lighting, the tax is 50 million yuan to solve morethan 1,500 people employment.
LED lighting companies rush to open the local market, seemed to confirm such an objective: the development of LED industry will gradually whereabouts of the domestic market. Zhang Xiaokang pointed out that China is the world’s largest lighting productsproducer and the consumer market. The future, the lighting will be incandescent, energy saving lamps to the LED light source, led high bay, the upgrading of the LED light source (LED industry in the upstream) will be mainly in the domestic market demand of supply downstream lighting manufacturers. Downstream sales of LED lighting manufacturers willface foreign and domestic markets.

Whether the led high power bulbs are to the blind pursuit of longer life?

Whether the led high power bulbs are to the blind pursuit of longer life?

LED lamps for its long life, and environmental protection advantages, become a populartrend of the moment lamps. Just how long the life of the LED lamps? Generally believednot fake LED life of 100,000 hours, LED made ​​of light would be to have a certain power, led high bay, the greater the power and cooling requirements of the higher, if the heat is not good, LED life is affected. Then there is the drive power supply part, and so on with the life ofthe LED lights. In addition also affects the quality of life, led high power bulb, so normal in the LED lighting industry, LED life value parameter should be 30000-50000 hours. In fact, such a lifealready meet most lighting needs, far beyond the energy saving lamps, LED lamps of the incandescent lamp life, whether you want the blind pursuit of longer life?
Incandescent lamp life of standard definitions for 1000 hours, but for a long timeoccupied a civilian home lighting market, led high power bulb, the most important reason is that the price advantage. LED lighting life have an advantage, but the price allows consumersprohibitive. I believe that LED lamps have a certain life span advantage, no need to gotoo much in pursuit of longer life, as necessary to the pursuit of too high light efficiency.Compared to the price of energy-saving lamps, LED lamps prices at a disadvantage, thepeople at home lighting in order to gain market share, led high power bulb, reduce costs, speed up thepopularization and application is king.
Recent U.S. Energy Star is being drafted to discuss the standards of the LED bulb,among the more controversial point is that life on the minimum requirements, the EPAmay be consumer lamp life requirements down to a minimum of 10,000 hours from25,000 hours, because 10,000 hours compared to three hours daily point count hasmore than nine years of life. The latest EPA’s standard is that you can nominal life, led high power bulb, the minimum of 10,000 hours, of course, if the test results, you can also nominal 25,000 hours or more.

New channel, its first profit–led highbay lighting

New channel, its first profit--led highbay lighting

“We must first to do.” To strengthen the LED channel construction, businesses need to firstLianhaoneigong with a complete product range and operational brand system in theworld market and the establishment of trust. The same time, companies must do a good job service, professional sales and service team and provide adequate financial support, led highbay lighting，especially in the current of the LED lighting market is still in cultivation period, sales channels and do not have complete experiences, led high bay after-sales products than traditional lighting need more intensity.

LED semiconductor lighting Why has not a large number of applications, other than price, the big problem lies in its stability. The ground has a nationally recognizedlaboratory, led highbay lighting，there are over 160 testing equipment, manufactured products must undergorigorous inspection to ensure the quality of the product is very stable. Moreover, theexisting products on the ground covering six major categories of light electrical appliances, commercial lighting, office lighting, decorative lighting, home lighting, industrial lighting, 28 Series 500 balance to meet one-stop shop to meet a variety of customer and to provide consumers with LED lighting solutions “.

Currently, LED lighting market is more confusing, most enterprises in the lighting industryto encroach on the LED industry downstream intervention threshold is low, many LEDmanufacturers are assembled sales hitting the market, relying on the cheap, led highbay lighting formal enterprises upsets difficult . LED lighting products was mixed, consumers are often unable to identify the products the pros and cons.

Always advisable to wait the amount. China’s LED lighting industry is in the construction phase of a new round of marketing channels. Manufacturers, distributors and sales terminals, this change will have a huge impact. Far-sighted investors, decision-makingahead, forward investment companies the upper hand, and may be a minority share ofthe pie.

LED high power light becomes lighting “potential shares”

 

LED high power light becomes lighting "potential shares"

 

The prospect of a rising star as the field of lighting, LED lights are very bright. The Bandung Hui Yang, lighting stores and many LED high power light business for their promotion, the relevant government departments also promote the development of LED industry. In 2009, the State Ministry of Science called “10 City, 10000,” semiconductor lighting application demonstration cities program, the first phase of the promotion of LED lights in 21 developed cities, the second phase of two million LED lights installed in 50 cities, to achieve the goal of saving one billion degrees.

 

From ordinary incandescent to energy saving lamps, energy-saving lamps to LED high power light , a new product out, need to go through a period of run-in period in order to be consumer awareness, which is a development stage, LED lighting is no exception. “Beijing deputy director of the Association of Lighting lamps & Lighting Fixtures market professional Committee, said Yang Jun, energy-saving lamps to replace incandescent, this process probably spent 3-5 years, alternative energy-saving lamps with LED lights, the process will be faster.

 

Ordinary incandescent lamps in the consumer’s attention is lopsided. October 1 this year, according to the incandescent phase-out road map “published by the National Development and Reform Commission and other relevant departments, the ban on the import and sale of 100 watts and above general lighting incandescent October 1, 2016 ban on the import and sale of 15 watts and more than ordinary incandescent. To obsolete the incandescent light bulb, energy-saving lamps replaced by one of the mercury due to production materials are unable to degradation of toxic materials is not conducive to the ecological environment, and its prospects are not optimistic, more environmentally friendly, energy-efficient led high bay lights will become a “potential shares”, ushered in the rapid development of the spring.

Distributors start to promote LED recessed downlights

 

The price is high, in fact, consumers do not have settled an account, that is, with LED lights saved electricity, can be offset by the LED lamp with an ordinary incandescent lamp, the difference between the energy-saving lamps. Also, LED recessed downlights more durable, unlike the other lights are easily damaged because of the number of switch. “Consumers do not understand these truths, in my opinion the root of the problem is the recognition of the LED lights should be improved LED business lighting market should be more universal knowledge to the customer.” Chang Yi ringing.

 

As the capital’s largest and highest grade of lighting stores, Bandung Hui Yang, already into action through various forms of activity trying to promote the LED recessed downlights. April 16, 2011, Bandung Hui Yang joint 20 LED manufacturers organized the first LED lighting exhibition, display of thousands of LED lamps for household lighting in the area of special provision of 5000 square meters of LED lighting. Now, in this year’s “high 3.15” social concern Consumer Protection Day, Bandung Meeting Ocean together, Fengtai District, Beijing Consumers’ Association to explore the bright future of LED lights form of a forum, and how to change the way people lighting life, it is the intention to promote a kind of led high bay lighting.

 

“Starting this year, the Bandung Hui Yang will store all public lighting to LED recessed downlights, set an example by their own actions to help the concept of promotion of environmentally friendly energy consumption.” Bandung Hui Yang, general manager of Xin Song vowed. The same day, Bandung Hui Yang was awarded Beijing the first “green energy consumer education base”.

Electrostatic damage to mains LED lights chip

 

Electrostatic damage to mains LED lights chip

 

 

Static electricity is a pernicious devil, the world countless electrostatic damage to electronic components, resulting in tens of millions of dollars in economic losses. So to prevent electrostatic damage to electronic components, is a very important task of the electronics industry, mains LED lights packaging, application of the enterprise do not take it lightly. Any link problems, will result in damage to the mains LED lights, the LED performance deterioration and even failure. We know that the human body static electricity (ESD) can reach about three kV, enough for the mains LED lights chip to breakdown damage in the LED packaging production line, the grounding resistance of various types of equipment to meet the requirements, it is also important, general requirements for the grounding resistance of 4 ohm, some of the occasions the grounding resistance even to achieve ≤ 2 ohms.

 

These requirements are for the electronics industry, people familiar with the key is in the actual implementation is in place, whether there is record. Not doing far as I understand private enterprise producing led high bay lights, anti-static measures in place, this is the most finding out grounding resistance test records, even if the ground resistance testing is also a once a year or a few years time, or have a problem check the grounding resistance, not knowing that the grounding resistance test is a very important task, at least four times a year (the test once each quarter), some of the requirements, the monthly for a ground resistance testing.
