Who can save China's LED lighting industry

"In the emerging industries where LED lighting is rapidly developing in the future, as long as 20% of general-purpose lighting uses LED by 2015, it will reach a market scale of 500 billion yuan, and will drive millions of people." I do not know how many people and entrepreneurs see this When I read the news, my heart thought: 500 billion yuan, as long as one percent of the market share is 5 billion, haha, very good. Even if not one percent, as long as one thousandth is 5 billion, 20% of profits will make one million per year no problem. One-thousandth of the market share is no problem, that is, according to the average apportionment, there are a thousand enterprises, there are one thousandth of the market! The prospect is too tempting! Do not think about it, and quickly dry LED lighting Therefore, on the market, people who understand LED, do not understand LED, do shoes, do clothes, do construction, do paint, do hardware and plastic... All of a sudden, all walks of life began to enter a high-profile LED lighting. This industry, and have played what "China's largest LED manufacturer", "China LED lighting leader", "LED lighting expert"....... It seems that as long as you work on LED, it is a high-tech expert who is just “high and high” and becomes a rich man with billions of assets. Enterprises are large enterprises with an annual output of billions of dollars.

However, what is the actual status of the LED industry in the country? Take the LED street lighting industry, most of the companies suffer losses, while a few non-losing companies are generally supported by traditional businesses. However, in spite of the loss, these company bosses are still "painful and happy." The reason for the pain is that, despite the high-tech LED, they did not get a few decent orders. Just got a few orders, the lights are installed on the road, but due to the serious decline of their own LED lamps, the more darker the lights, the hearts of more and more afraid, I do not know one day, the light is bad to no light, How to explain to the government and the people? At present, with their company's technology can not solve the LED Light fixtures on the light failure, heat dissipation, light distribution and other problems. Although these cannot be spoken by outsiders, they are still bragging about the “×× brand and illuminate the world”, so the conflict is painful. Despite the pain, I think there is a huge pie that can be eaten in China with a market of several hundred million yuan. And if the packaging is good, it can also be used to collect money from a stockholder. Considering that the Chinese government has never hesitated about the future of LED lighting, it will also introduce a series of preferential policies and support measures to support the development of the LED lighting industry. At the thought of this, these entrepreneurs would be pleasing. In any case, the Chinese government's money is good and flabby, and it is just a matter of playing a full-fledged, full-fat face, continuing to flicker, and gambling on it! This is the status quo of China's LED lighting industry - painful endurance, happy fantasy. However, they did not seriously think: Where did this pain come from, and how did you eliminate and alleviate this pain?

There is no doubt that the Chinese government can support the demonstration of LED lighting. It can be said that the governments of all countries in the world support the most. The "Ten Thousand Cities and Ten Thousands" demonstration project has already thrown billions of yuan into it. However, how is the actual effect? ​​Many LED street lamps have to be removed due to severe light failure for several months, and some lamps are still on, but they are gradually dimming. In order to face, they still die! A street lamp of a well-known company sent a team of more than 100 people to "fire" repairs throughout the country. People can not help but ask: What are the causes of all these losses? When thinking carefully, what is hateful is that China has become a testing ground for some so-called advanced advanced LED lighting! Although many LED street lamp manufacturing enterprises have become victims, But it is still in the dark. They even smugly declared: "We have won nearly 2000 kilometers of demonstration projects of LED lights it!" These companies have become some foreign companies make the Chinese government, but also to earn taxpayers' money. Because a company advertises: “We use the LED light source of the well-known brand of the importing country x company. Its price is as high as nearly RMB 30 per watt. This way, we sell a hundred-watt LED lighting. The price of 67,000 yuan is not too high!” Our government paid 6,000 yuan per lamp. In a few years, the 2000-kilometer street lights would cost more than a billion yuan, and x foreign companies would easily take them. Going 50%. Those who have a little bit of semiconductor knowledge know that LED wafers are extremely cheap to manufacture, and if foreign advanced technologies are manufactured, the cost will be even lower. Originally only 10 yuan a watt of things, how suddenly sold 30 yuan a watt? These companies also willingly to promote, advertised that they are using imported brands to help these foreign companies earn money to Chinese people! What can these companies get? It's ridiculous to say that they don’t get the other half of the renminbi. What they got was that they used foreign LED light sources to produce substandard LED lighting products and they couldn’t get government projects. The outcome of your own brand. At this time, these foreign companies will control you? What they have advertised as "X. Core, China's sentiment" turns out to be using their "black heart" to earn money for the Chinese people! So we have to reconsider. Asked himself: Why did you use foreign famous brand products, and finally this is the end? This is an important issue that our government officials, experts, and LED lighting manufacturers in particular must seriously think about! We can only truly understand this issue. Through understanding, we can only save our LED street lighting industry, so as to enable our LED lighting manufacturers to avoid going astray. The country's new 500 billion yuan lighting industry can develop healthily.

Here, everyone can not help but ask, where is the key to the problem? We may as well ask: Which countries have the best LED? Everyone may invariably believe that it is the United States, Japan, Germany, and South Korea. Let us think about it. Since these advanced capitalist countries have such a good technology, why did they not spend billions or billions of dollars on LED demonstration projects in the "Ten Cities and Ten Thousand Cities?" Do you give Chinese people demonstration projects? This is where the problem lies. Because they know: Demonstration is trial, it is to pay the price of risk. Isn't the Chinese very clever? Learn about the world's advanced technologies. This can be due to the fact that the Chinese have tasted bitter fruit in LED lighting. Foreigners not only sold us LED high-tech products, but also sold us an encapsulated LED light source model to guide our Chinese companies to manufacture lighting fixtures according to this packaged LED light source model. As mentioned earlier, the LED lamps that use the LED light source mode of thinking of foreigners can be thought of as endings. Foreigners think about it: Anyway, what the Chinese government currently has is money, and it doesn't matter if it costs money. Is it not reluctant to spend money on research and development in China? Then you can use your money to buy lessons! When the Chinese finally understand it, there will be plenty of foreign exchange. Has been earned by foreigners. And our government officials and some experts and scholars, and even more entrepreneurs, are still claiming that our LED lamps use imported light sources! It can be said that the entire industry has been fooled by foreigners! Because foreigners Starting from selling a packaged LED light source to the Chinese, the industry as a whole will have to detour. Because no matter what your production plant, no matter how high your technology, as long as you use this LED light source as a lamp, you must design LED lamps based on the characteristics of this light source. As a result, LED lighting fixtures with dozens or even hundreds of LED light sources of the same structure were born in China. The structure of these lamps is basically the same, that is, the LED light source is encapsulated by a LED crystal on a heat sink, and the light emitting surface is protected by a resin lens and the light emitting angle is good. Dozens, hundreds of such light sources are mounted on a printed circuit aluminum substrate. On the other hand, the aluminum substrate is again mounted on an integrated heat sink housing. In order to make light distribution, a lens made of PC or PMMA material is added to the LED light source, commonly known as "peanut lens." Then in order to waterproof and dustproof, you must add a glass lampshade to seal. Alternatively, instead of using the “peanut lens” to distribute light, a coated reflector is used to create individual LED light source cavities for reflection light distribution. Then install the driver, after the power is turned on, the LED lights up, and everyone is happy. The "high-tech" LED luminaires have been successfully developed! However, after the lights have been lighted for a while, problems are discovered. The internal junction temperature is too high, the light fades too much, and the light fades by tens of percent in less than a few months. So all manufacturers are racking their brains, do everything possible to find ways to how to reduce the LED light source to the LED heat sink, to install the printed aluminum substrate, to the thermal resistance between the radiator. As a result, there is no other way but to fill it with a low thermal resistance thermal paste. However, where is the thermal resistance of low thermal resistance? Only foreigners have it. Therefore, all manufacturers will buy at all costs, even if it is a high price of tens of yuan per gram, but also to buy it! Anyway, this has been made by a foreigner slamming! After spending money, Although the thermal resistance of the luminaires has been reduced, the light failure is still serious! At this time, the foreigners said that your Chinese PC lens, the material of the PMMA material is too bad, easy to aging light decline, and only use our foreign The material is fine. As a result, many manufacturers have imported large quantities of foreign PCs and PMMA materials, thinking that this would reduce light failure. As everyone knows, whether imported plastic or imported PC material, can not fundamentally solve the problem of LED cooling and light failure, but by foreigners flickered money. So far, it can be said that Chinese companies use this pattern of light sources designed by foreigners as LED luminaires, and no one really solves the problem of heat dissipation and light failure of high-power LED luminaires. This is the current sadness of China's LED lighting industry.

Why did you get into this circle? A senior scientist at NASA said: The current LED light source package mode is the packaging mode of LED's early instructions and display lights, even if the W-level package mode is only one This kind of improvement only does not meet the requirements of the low thermal resistance and high light output and low light attenuation required for the 100W power light source lighting package mode. It is no wonder that LED lighting fixtures made by most Chinese companies cannot break the heat dissipation and light failure problems. Because the light source mode used in this lighting fixture is used as a display and indicator mode! It is ridiculous to think that so many smart Chinese people have been fooled for many years! However, so far, Chinese LED lighting companies that can wake up There are several? Even a few experts are still unrealistic shouting: LED lamps produced by discrete light sources are the most dispersed, and are the best heat dissipation structure model. It is awesome to think about this! These experts, professors are the elite of the nation, should have been at the forefront of science and technology, but they have also been fooled by foreigners. They do not think about it, study practical LED lighting technology with Chinese characteristics, but help foreigners flick to Chinese people! Of course, this is only a few people, and there is nothing to worry about! It is an academic debate! Let them fight go with. Fortunately, the LED lighting industry has developed to this day. Many of our government officials, experts, professors, and researchers have found this problem, and in some areas have stopped using this LED light source pattern for instruction and display. Demonstration Project. Started thinking of the real lighting industry product development direction and mode: LED lighting is not wrong, LED development prospects are not wrong, the wrong is wrong in the product structure model. Because the structure pattern of the lighting products of this type of foreign light source mode causes the LED lamps to dissipate heat, the light efficiency does not come, and the light decline is serious. In fact, the correct method is not difficult: it is to change the current LED light source package mode and lamp structure mode. Using the structure pattern of low thermal resistance and low light-failure LED light source and LED luminaire that is invented by our own innovation and has its own intellectual property and meets the needs of high-power lighting.

Fortunately, an LED light source and lighting model product that can truly meet lighting requirements has emerged in the Chinese market, and companies have their own intellectual property rights. Some good company's R&D team has continuously collaborated with professors and professors of the Institute of Electric Light Sources at Fudan University in Shanghai and the Institute of Optoelectronics at Zhejiang University to begin research and development of low thermal resistance integrated high power LED light source modules, integrated light distribution modules, rare earth heat sinks and heat sink modules, And power drive control module. They excluded quick success, impetuous interference, concentrated research, and worked hard to overcome one difficulty. Through the optimization and combination of various modules, real high-power lighting LED lamps were realized. At present, the company represented by this company adopts domestic LED chip package 10-100w integrated LED light source module, the light source luminous efficiency has exceeded 120lm/w, 120W LED lamps produced with this light source have been inspected by the national electric light source quality supervision. The center (Shanghai) has detected that the entire lighting efficiency has reached 90.9 lm/w, and its high luminous flux integrated high-power monolithic LED lamp technology is at the leading position in the world. Its LED junction temperature (ambient temperature 25°C) has been tested to 50°C. The company’s demonstration lamps installed in Suzhou Industrial Park have not been tested for light failure after six months of monitoring. The LED lamps installed in Kunshan light up for 24 hours and have been continuously running for more than 25,000 hours, and their measured luminous decay is less than 10%. The company has obtained such good test and inspection data for its products. The raw materials used are silica gel and gold wire used for protection. The materials used are other materials such as LED wafers, liquid crystals for solid-crystalline heat transfer, phosphors, ceramic packaging substrates, and rare earth aluminum. Alloy heat-dissipation materials, glass materials for light distribution lenses, etc., all use domestically produced materials and materials developed by the company's own intellectual property.

I believe the LED lighting industry, after painful thinking, we will wake up and reach a consensus: Only adhere to the road of independent innovation, increase the development of LED from the wafer to the LED light source packaging structure and LED lamp structure research and development, from the basic raw materials research Began to increase investment, immersed in innovation, in order to get out of the current embarrassing situation everyone is suffering. At present, the entire lighting efficiency of high-pressure sodium lamps is in the range of 60-70 lm/w. To make LED lamps save energy by more than 60% than that of sodium lamps, the overall lighting efficiency of LED lamps must be greater than 100 lm/w, so as to save more than 60% energy. In order to achieve the goal of energy-saving and emission-reducing low-carbon economy in our country, if some companies still use LED lamps with luminous efficiency of 60-70lm/w and deteriorating light to replace the original high-pressure sodium lamps with luminous efficacy of 60lm/w, they will scream energy savings. 60-80%, this is the performance of self-deception. Such a company cannot save China's LED lighting industry. If you really let such a company go "to lead the Chinese LED lighting industry," imagine, where will China's LED lighting industry run under its "leadership"? Therefore, only through independent innovation, abandon the wrong LED lighting product design and structural model, and innovate LED products with high efficiency and high quality that truly meet the LED characteristics and meet the needs of lighting in order to save the Chinese LED lighting industry!
