At the same time as the rapid development of the industry, the market has also expanded rapidly. On the one hand, traditional power supply manufacturers have launched LED power products, on the other hand, many entrepreneurial companies have also been established. However, the power supply technology is not yet mature, the relevant standards have not been introduced, and the market is chaotic. Relevant experts believe that the market will eventually lead to a situation dominated by a few giants, marketing strategy and product quality are the key to success.
Market expansion, price war
The industry in 2010 was mixed, and the market expanded rapidly, but not all participants made money. Most of the street lights did not make money, and the led tunnel lights earned some living expenses. The enterprises that do commercial lighting have strong foreign trade ability, and chip companies have made money. Many domestic chip companies have been in a loss state before, and there was a turnaround in 2010. Packaging companies make money, because the whole year of 2010 is "not married."
It is worth noting that most LED power companies are also making money, but there is no shortage of goods like this, because LED power is technically a traditional electronics industry, and China's electronics industry already has strong manufacturing capabilities. However, the industry has not risen for a long time, and the price war has started, especially in the field of low-power power supplies. It is understood that the price of low-power LED power supply has been very transparent, such as the price of power supply is generally around twenty-four.
However, the power supply is still at a high profit margin. One of the reasons is that the technical threshold is relatively high and the capital investment is large. Another reason is that high-power LED power supplies are mainly used in street lights and tunnel lights. Currently, these lamps are mainly used for government demonstration projects. In order to demonstrate good results, the street lamp manufacturers used the best accessories (at least on the sample lamp), which caused the manufacturers to put forward higher requirements for the power plant and increased profits.
The survey found that the business of LED power plants such as Mingwei, Infineon and Moso has increased several times in 2010.
Power technology is not yet mature
It is understood that the quality of LED power supply for indoor lighting is very unstable now, and one or two of the ten will flash after a period of time.
Huagui Chao, chairman of Infineon, believes that some small factories now only consider that they can work when designing power supplies. They do not consider the working environment and sometimes need to work in harsh environments.
North Huihua Xu Changchun believes: "The threshold of LED power supply is not high, but it is not easy to do well. It needs to be well developed, good materials and good production. Sometimes the sample is no problem, but it may appear after a large amount. Batch problem." "Some components in Guangdong are quoted in pounds, and we use the price quoted," he added.
Although most of the faults occur on the power supply, they cannot blame the power supply company. LED street light expert Xu Liancheng told reporters that power failure is the result of a multi-factorial combination of effects, many of which are caused by unreasonable design of lighting companies. In order to effectively reduce the power failure, it is also necessary for power companies and lighting companies to strengthen interaction and work together.
According to incomplete statistics, about 80% of the faults caused by LED lighting products come from power sources. From the past few years, the product packaging technology has been continuously improved and the heat dissipation technology has been continuously developed. The stability of the light source has reached a relatively good level, even if there is that It is also the light decay and color drift, which is mainly caused by the unreasonable heat dissipation design. The situation of direct necrosis is very small. Relatively speaking, the problem of power supply is much more serious. When a problem occurs, it is usually a direct death or flashing, and the frequency of occurrence is relatively high.
Of course, there are still many shortcomings, such as the lack of standards, which leads to increased maintenance costs for manufacturers, which is not conducive to the development of the LED industry.
The unique flat cable shape allows for a cleaner and safer installation. You can easily and seamlessly make the cable run along walls, follow edges&corners or even make it completely invisible by sliding it under a carpet.
