With the rapid development of the LED lighting industry, the LED power supply market is also rapidly expanding. On the one hand, traditional power supply manufacturers have launched LED power products, on the other hand, many entrepreneurial enterprises have also been established. The power supply technology is not yet mature, 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 victory. Market expansion price war begins The LED 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 those who made LED tunnel lights made some living expenses. Among the enterprises engaged in commercial lighting, the foreign trade ability is strong, and the chip companies are making money. Many domestic chip companies have been at a loss before. A turnaround occurred in 2010. Packaging companies are making money, because LED modules are "not worrying about marrying" throughout 2010. It is worth noting that most LED power supply companies have also made money, but there is no shortage of products like LED chips. The reason is that LED power supplies are technically in the traditional electronics industry. China ’s electronics industry already has strong manufacturing capabilities. But the industry hasn't been around 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 LED fluorescent lamp power supply is generally around twenty-four or five. However, high-power LED power supplies are still at a high profit margin. One of the reasons is that the technical threshold is relatively high and capital investment is large. Another reason is that high-power LED power supplies are mainly used in street lights and tunnel lights. At present, these lamps are mainly used in government demonstration projects. In order to demonstrate good results, street lamp manufacturers use the best accessories (at least on the sample lamps), which has caused the manufacturers to put forward higher requirements for power plants and also increased profits. In order to demonstrate good results, street lamp manufacturers use the best accessories (at least on the sample lamps), resulting in high profits for high-power power supplies. The survey found that the business of LED power manufacturers such as MEAN WELL, INFINITE, and Mosuo all increased several times in 2010. Power technology is not yet mature It is understood that the quality of LED power supplies for indoor lighting is very unstable, and one or two of the ten will appear to flicker after a period of time. Inquiry Chairman Hua Guichao believes that some small factories now only need to consider working when designing power supplies, without considering the working environment, and sometimes LED street lamps need to work in harsh environments. Northern Huihua Xu Changchun believes: "The threshold of LED power supply is indeed not high, but it is not easy to do well. To do good research and development, good materials and good production, sometimes the samples are no problem, but it may appear after a large amount Bulk issue. "" Some components in Guangdong are quoted on a catty basis, and we use quotes on a per piece basis, "he added. Although most of the failures of LED lamps occur on the power supply, they cannot blame the power supply companies. Xu Liancheng, an LED street light expert, told reporters that the power failure is the result of a multi-factor combination, many of which are caused by the irrational design of the lighting company. In order to effectively reduce the failure of the power supply, it is also necessary for the power supply enterprise and the lighting enterprise to strengthen interaction and work together. According to incomplete statistics, about 80% of the failures caused by today's LED lighting products come from the power supply. From the past few years, the packaging technology of LED light source products has continuously improved and the heat dissipation technology has continued to develop. The stability of the light source has reached a relatively good level, even if it is said There are also light decay and color drift, which is mainly caused by the unreasonable heat dissipation design. There are very few cases of direct necrosis. Relatively speaking, the problem of power supply is more serious. When a problem occurs, it is usually a direct light 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 and is not conducive to the development of the LED industry.
