LED power chaos: LED product failure 80 comes from power supply

Polaris power network news: While the industry is developing rapidly, the market is also expanding rapidly. On the one hand, traditional power manufacturers have launched LED power products, on the other hand, many entrepreneurial enterprises have also been established. However, the power technology is not yet mature, the relevant standards have not been introduced, and the market is in chaos. Relevant experts believe that the market will eventually lead to a situation dominated by a few giants, and marketing strategy and product quality are the key to success. Market expansion, the price war started. The industry in 2010 was mixed. The market expanded at a high speed, but not all participants made money. Most of the street lamps did not make money, and the led tunnel lights earned some living expenses. Among the commercial lighting enterprises, the foreign trade ability is strong, and the chip enterprises have made money. Many domestic chip companies have been at a loss before, and there has been a turning point in 2010. Packaging companies make money, because the entire 2010 is not married. It is worth noting that most LED power supply enterprises have also made money, but there is no shortage like that, because LED power supply belongs to the traditional electronics industry in technology, china's electronics industry already has strong manufacturing capabilities. However, the industry has not risen for a long time, and the price war has already started, especially in the field of low-power power supply. It is understood that the price of low-power LED power supply is already very transparent, for example, the price of power supply is generally around twenty-five. However, the power supply is still in 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 supply is mainly used in street lamps and tunnel lamps. Currently, these lamps are mainly used in government demonstration projects. In order to demonstrate good results, street lamp manufacturers have adopted good accessories (At least on the sample lamp) As a result, manufacturers have put forward higher requirements for power plants and raised profits. In order to demonstrate good results, street lamp manufacturers have adopted good accessories (At least on the sample lamp), Resulting in high profits of high-power power supply. The survey found that the business of LED power manufacturers such as Mingwei, Infineon and maoshuo increased several times in 2010. The power supply technology is not yet mature. It is understood that the quality of LED power supply for indoor lighting is very unstable, and one or two of the ten will flash after a period of time. Hua Guichao, chairman of Infineon, believes that some small factories now only consider the ability to work when designing power supplies, without considering the working environment, and sometimes need to work in harsh environments. North Huihua Xu Changchun believes that the threshold of LED power supply is not high, but it is not easy to do it well. It is necessary to do good research and development, good incoming materials and good production. Sometimes the sample is no problem, however, batch problems may occur in the future. Some components in Guangdong are quoted by catty, while we use quoted by catty. He added. Although most of the faults occur on the power supply, they cannot be blamed on the power supply enterprises. Xu Liancheng, an LED street lamp expert, told reporters that the power failure is the result of a combination of multiple factors, many of which are caused by unreasonable design of lamp enterprises. In order to effectively reduce the failure of power supply, it is also necessary for power supply enterprises and lamp enterprises to strengthen interaction and work together. According to incomplete statistics, about of the faults caused by LED lamp products today come from the power supply. In recent 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 it is said that it is also light attenuation and color drift, which is mainly caused by unreasonable heat dissipation design. There are very few cases of direct necrosis. Relatively speaking, the problem of power supply is much more serious. Once a problem occurs, it is usually a direct dead light or flashing, and the frequency of occurrence is relatively high. Of course, there are still many deficiencies, such as the lack of standards, which leads to the increase of maintenance costs of manufacturers and is not conducive to the development of LED industry.
