LED power chaos: LED product failure 80% from power

With the rapid development of the industry, the market is expanding rapidly. On the one hand, the traditional power suppliers have launched LED power supply products, on the other hand, many entrepreneurial companies have set up. However, the power technology is not yet mature, the relevant standards are not introduced, the market chaos. Experts believe that the market will eventually lead to a handful of giants led, marketing strategy and product quality is the key to victory or defeat.

Market expansion, price war

The industry was mixed in 2010 and the market expanded rapidly, but not all participants made money. Do most of the street did not make money, do LED tunnel lights earn some living expenses. To do business in foreign trade enterprises in the strong ability to make money, chip companies have to make money, before a lot of domestic chip companies have been at a loss, in 2010 there has been a turn for the better. Packaging enterprises to make money, because the whole 2010 are not worried about marriage

It is worth noting that most of the LED power companies are making money, but not like that out, because of the power LED is technically belongs to the traditional electronics industry, electronic industry Chinese already has a strong manufacturing capability. But the industry did not rise long, the price war has begun, especially in the field of low-power power. It is understood that the small power LED price is very transparent, such as power supply in the general price of about twenty-four.

However, the power is still in the high profit, one reason is the relatively high technical threshold, large capital investment. There is also a reason for the high power LED power supply is mainly used in street lamps, tunnel lights, the current lighting is mainly used for government demonstration projects. Street lamp manufacturers in order to demonstrate good results, the use of the best accessories (at least on the sample lamp), resulting in the power plant manufacturers to put forward higher requirements, but also to raise profits.

The survey found that meanwell, ledone, mosopower LED power supply manufacturers business in 2010 have increased by several times.

Power technology is not yet mature

It is understood that the quality of the interior lighting with LED power supply is very unstable, there will be ten of them in a flash phenomenon after a period of one or two.

Ledone chairman Hua Guichao believes that the time is now part of the small power plant design to consider only to work on it, did not take into account the work environment, and sometimes need to work in harsh environments.

Huihua Xu Changchun said: "the LED power threshold is not high indeed, but do not easy to do good, good research and production materials, sometimes sample no problem, but after a large amount of possible quantity problem. "Some of the components in Guangdong are quoted by Jin, and we use the quoted price. He added.

Although most of the fault occurs on the power supply, but can not blindly blame power companies. LED street lamp expert Xu Liancheng told reporters that power failure is a result of a combination of factors, many of which are caused by the unreasonable design of the lighting business. Want to effectively reduce the power failure, but also need to strengthen the interaction between the power companies and lighting companies to work together.

According to incomplete statistics, about 80% of the faults of LED lighting products produced from the power supply, the continuous development of a few years from the products continuously improve packaging technology and cooling technology, the light stability has reached a good level, even if it is a bad light and color drift, which is mainly caused by the unreasonable design of the heat dissipation. Direct necrosis of the situation has been very small, relatively speaking, the problem of power supply to be more serious, a problem is usually a direct death or flashing lights, and the frequency is relatively high.

Of course, there are still many deficiencies, such as the lack of standards, which led to increased maintenance costs of manufacturers, is not conducive to the development of LED industry.
