LED road lighting: transnational giant set traps?

As far as LED is concerned, what we can imagine is that it can make a brilliant contribution to the cause of energy conservation in today's society. From the theoretical point of view is the LED with its long life low voltage DC power supply, energy saving and environmental protection, no stroboflash advantages make it a born beauty society set thousands of pet in one. So that individuals, businesses, government, society are LED and crazy. It seems as long as a light source with LED shine, unlimited future, the role of LED by various social on speculation miraculous, seems to be the only LED is such savior. I could not help but think of a famous song "Dongfanghong" lyrics: it is the Savior of the people, hu er contract, it is the great liberator of the people.

LED may not be a lifesaver

LED really is the human society to solve the current energy shortage situation of the Savior? I am afraid not, cause less in the current LED industry development status and market conditions, it is impossible to become a savior.

LED true role orientation must not be placed only in China, such as an emerging market countries to look at. In order to understand its role and status, it is necessary to put it into the vertical historical coordinates and horizontal international coordinates of this new positioning system to do fine analysis.

In fact, lighting products such as LED as early as a few decades ago in PHILPS and OSRAM labs. But why is this the rich international from the head there is no large-scale promotion? We can believe that if the two from the same as the energy saving push Chen Guang LED. I'm afraid that LED is energy-saving lamps bloom the globe today, but the wily head is taken from a hundred years "gentlemen do not" and strategy. So we hear the world that LED will head into battle light ruler future official accusation. But it has not yet begun to open up the market, what is the secret here?

There may be only one reason. LED lighting is probably a big trap, is a trap for multinational companies are developing countries such Chinese dug under the, through the advantages of large-scale publicity LED so-called developing countries in order to let this beauty force to the development of LED lighting market, and then realize the graph not to be divulged.

What attempt? The term may be difficult to do, but still can be seen at the end of one or two. Remember the end of the Qing Dynasty, the Qing Dynasty Beiyang Navy Japan generous to sell a number of shells to Sino Japanese goodwill, soon took place on the sea in the Sino Japanese dispute, when our Lord Li Hongzhang for decades to tighten their belt of Beiyang army against the crown on the only, only to find shells is full of dumb gun, the result as can be imagined since the defeat is undoubtedly.

PHILPS, OSRAM, GE, SIEMENS why so keen to promote LED lighting and not eager to open up the market? This and the above mentioned squib is a reason, because LED technology is quite mature, immature production more, larger negative impact on the society and the country. The more serious is the cause of national waste valuable resources, financial damage, enterprises have lost the opportunity of development and catch up with the multinational the pivot and the platform. It's like the Sino Japanese naval squib damage to the Beiyang fleet, light by heavy The whole army was wiped out.

Transnational from the head is not a large-scale promotion is not related to the immature technology, but also has a close relationship with Western governments. In a mature and developed market economy conditions, any new technology to the market are numerous tests by love of the government, and then through a special scientific evaluation committee and the government of the verification experts before implementation.

The advantages of LED who knows, the scope of its application and space is also great, but the lighting is not used by the U.S. government and the EU LED optimistic. The government's calm and self-discipline and long-term vision of LED lighting is not as rapid as fluorescent.

LED squib phenomenon

Then LED lighting "squib" phenomenon is what table in what place?

Some people think that: LED as an indoor home lighting can not be compared with the small power gas discharge lamp, but also can not compare with pure three primary powder light! There are three reasons:

A: even if all of the defects of LED are changed, its use value is increased, but its sales price is high, in the age of personality, reasonable periodic replacement, will also cause waste.

Two: in the era of advocating a happy and healthy, LED light line, color and other defects will be able to stop today.

Three: in the gas discharge which is widely used in outdoor high-power lighting era, regardless of LED color, replacement of high cost and so on, only a light, can make the LED city race to outdoor lighting.

The public knows that the road lighting with LED in order to be more practical and effective lighting, must have a higher degree of illumination. To have a higher degree of illumination, it is necessary to increase the power of the product. But the attendant problem, increase product power is bound to increase the heat energy, heat energy increase will lead to decay, decay products lead to premature damage. So a core problem of high power LED is how to solve the problem of heat dissipation and decay. These two problems are not isolated from the two problems, but mutual influence and mutual restraint.

To solve the heat and light problem. Many domestic enterprises exhausted, and we all agree that the use of aluminum substrate cooling and installed on the lamp fan, fan air convection cooling. On the face of it, this is an absolutely perfect idea, but the actual use of the same problem
