When it comes to LEDs, what we can imagine is because of its brilliant prospects for making outstanding contributions to today's social energy-saving business. Yes, from the theoretical point of view, LED has a long life of low-voltage DC power supply, energy-saving and environmental protection, no stroboscopic and other natural beauty advantages make it a favorite of the society. So that individuals, businesses, governments, and society are all crazy with LEDs. It seems that the light source is radiant as long as it touches the LED, and the future is infinite. The role of LED is squandered by various theories in the society. It seems that only LED is the energy-saving savior. The author could not help but think of the lyrics of a famous song "Dongfanghong": it is the savior of the people, and it is the great savior of the people.
LED may not be a big savior
Is LED really the savior of human society to solve the current shortage of power? I am afraid it is not. In the current LED industry development technology and market conditions, it is impossible to become a savior.
The true role of LEDs must not be seen only in an emerging market country like China. To recognize its role and status, it is necessary to put it into a new positioning system of vertical historical coordinates and horizontal international coordinates for detailed analysis.
In fact, such products as LEDs for lighting have appeared in the laboratories of Philips and Osram decades ago. But why is there such a large-scale promotion of this wealthy international distance? We can believe that if these two are the same as the energy-saving lamps to promote LED. I am afraid that LED is the world's energy-saving lamps that bloom around the world, but these savvy and far-sighted ones are taking "the gentleman does not do it" and the strategy. So what we hear is the global warfare that they are about to become the ruler of future light sources. However, it’s too late to start to open up the market. What is the truth here?
There may be only one reason. Illumination LEDs may be a big trap, and a trap that multinational companies are digging for developing countries like China, that is, through large-scale publicity of LED so-called advantages, let developing countries use the power of the country to develop LED lighting. The market then implements its unspeakable picture.
What is the attempt? It may be difficult to say a word, but the end is still a glimpse. I remember that in the last years of the Qing Dynasty, Japan generously sold a number of artillery shells to the Northern Ocean Navy of the Qing Dynasty to show the goodwill between China and Japan. Soon, Sino-Japanese War occurred in the Sino-Japanese War. When our Li Hongzhang was ten years old, the Beiyang Army’s confrontation day was established. Only when the crown was discovered, it was discovered that the shells were all dumb guns. The result was conceivable, and it was undoubtedly defeated.
Why are Philips, OSRAM, GE, and Siemens so keen on promoting LED lighting and not eager to open up the market? This is the same as the dumb gun mentioned above, because the technology of LED is quite immature. The more mature products are produced, the larger the scale, the more negative the impact on society and the country, the more serious the country. Waste of precious resources, impaired financial resources, enterprises lose opportunities for development and catch up with the fulcrum and platform of multinational enterprises. This is like the damage of the Beiwu Fleet to the Beiyang Fleet in the Sino-Japanese Sea Warfare.
It is not related to the immature technology, but also has close ties with Western governments. Under the mature and developed market economy conditions, any new technology must be tested by the government, and then verified by various experts and evaluated by a special scientific committee of the government.
The advantages of LEDs know that the scope and space of their applications are also large, but LEDs for lighting are not favored by the US government and the European Union. The government's calmness and corporate self-discipline and long-term vision make LED lighting not as popular as fluorescent lights.
LED dumb phenomenon
So where is the "dumb gun" phenomenon of lighting LEDs?
Some people think that LED as indoor home lighting can not be compared with low-power gas discharge lamps, and can not compete with pure three-primary powder lamps! There are three reasons for this:
One: Even if all defects of LEDs are changed, their use value is improved, but their sales price is high. In the age of personality, reasonable periodic replacement will also waste.
Second: In the era of advocating happiness and health, LED lighting, color rendering and other defects will be able to stop today.
Three: In gas era, it is widely used in the era of outdoor high-power lighting, and regardless of the color rendering of the LED, the high cost of replacement, etc., only the light decay can make the LED city outdoor lighting competition lose. .
It is well known that LEDs for road lighting must have a higher illumination for more practical and efficient illumination. To have a higher illumination, you must increase the power of the product. But the problem will follow, the increase of product power will inevitably increase heat energy, and the increase of heat energy will inevitably lead to light decay, which leads to premature product damage. So a core issue of high-power LEDs is how to solve the problem of heat dissipation and light decay. These two problems are not two isolated problems, but they interact with each other.
To solve the problem of heat dissipation and light decay. Many domestic enterprises are exhausted, and everyone agrees that the aluminum substrate is used to dissipate heat and install a fan on the luminaire, and the air convection is cooled by the fan. On the surface, this is an absolutely perfect idea, but the same problems in practical use are repeated.
one. What is the power of the fan? If the power loss of the fan exceeds the energy saving effect of the LED, then where does the fan work? What is the role of LED lamps?
two. LEDs for roads have special requirements for waterproofing, dustproofing and rust prevention, and require a high degree of protection. In order to make the LED work in the outdoor environment for a long time, it is best to seal, but how to install the fan's luminaire is sealed, then the change of the natural environment will quickly lead to the rapid retirement of the entire luminaire product.
three. Repair and protection costs. The cost of inspection, inspection and maintenance of fans and other equipment has to be budgeted. This is not a small expenditure, labor, time, money, replacement consumption, must be converted into the cost of lamps. In this way, it is better to make up for the increase in the cost of the non-electricity damage.
Of course, under the current scientific conditions, the problem of light decay and heat dissipation cannot be solved, but the cost of solution far exceeds the economic benefits brought by energy conservation. So these are some of the less economical practices.
The formulation of the national standard for LEDs for roads is conducive to enabling enterprises to recognize the form and stage of the development of the LED industry. Do not blindly invest, and do not be blindly optimistic.
Therefore, it can be seen from various analyses that the large-scale use of LEDs has not yet arrived, but it does not mean that these problems have been solved by LEDs. It is an unknown time for Guan Jian to solve the new decisions.
They regard China as a test article
Although the lighting use of LEDs still needs to wait, it is full of decoration in terms of decoration. Because its color is changeable, the light is soft, and the life is long. The safety of DC low-voltage power supply is welcomed by many users. This is also an important reason why LED is popular in the field of global color decoration and landscaping. Cross-country heads clearly know all the advantages and disadvantages of LED products, and promote the advantages of LED as much as possible. One of the important purposes of this is. Take developing countries as a technology testing platform, paving the way for the development of more perfect and alternative advanced technologies for the future at the expense of developing countries.
For example, in the past two years, China has been enthusiastically promoting LEDs from enterprises to the government. The use of street lamps in government projects does not seem to be harmonious if it does not use LEDs. It seems that it is not a construction-saving society, but some projects use LED street lights for several months. Not all of them became a yin forest. Because the LED light decays too fast. The luminaire loses its normal illumination at the fastest speed. The entire streetlight project was pushed back again. An LED streetlight project in Foshan, an LED industry in Heshan, is one of the most obvious examples of this card.
In fact, no matter what kind of technology, whether it is a business or a government agency, it should be able to withstand loneliness, and should be examined in a scientific and socially responsible manner. It should not be viewed only in terms of the market's quick success.
At present, China's LED lighting enterprises have been in a state of flux, and the number of energy-saving lamps companies is much higher. It seems that every effort is made to unify the LED market, and it seems that the dream of replacing traditional light sources with LEDs must be realized. However, friends, especially the bosses, you must be calm. If you can replace the traditional light source as you imagined, why are your ancestors, Fei Lijun and Osram still not working?
The reason why Philips, Osram and GE Lighting can develop into a hundred years is a profound historical origin. For a historical origin, it is an effective combination of technology accumulation and strategic vision. If the company does not have a certain strategic vision, the enterprise does not understand. The real trend of the market. It is difficult to make a company a strong enterprise in a century-old store.
In addition, the government as a macro-controller of the market should not let enterprises push forward. The government should measure whether it should promote a certain technology from the perspective of the whole society. The technical products promoted by enterprises only need to be responsible for the sensible society, but the government To be accountable to the public, it is more important to take the lead in pushing the technology to the city.
The governments of Taiwan, Japan, and South Korea clearly know that some key issues of LED lighting cannot be solved under current scientific and technological conditions, so they have always opposed the promotion of LED. Only governments across China have begun to build so-called LED lighting industry parks under the advocacy of enterprises. It can be said that this so-called government initiative will not only fail to obtain good market returns but also become an important financial burden.
Faced with the cold and hot of LED lighting, I advised Jun to take the tributary as the mainstream.
It is beneficial to keep the chicken feathers as an arrow and keep a clear head in the country and the people.
