In recent years, with the support of policies, the output value of the entire LED lighting industry has shown explosive growth. As a key component of LED lighting, the LED driving power industry has naturally ushered in development. According to statistics, as of the end of 2012, China has a certain scale of LED drive power companies (referring to enterprises that sell LED drive power, and do not include application companies that only produce power for them). Among them, 90% of the drive power companies are involved in LED indoor lighting power. Judging from the supply and demand situation, LED low-power power supply has already experienced overcapacity, especially low-power indoor lighting power supply, and the market has disorderly competition.
Drive has always been known as the "heart" of LED lamps, mastering the life and death of lamps. However, driving quality and safety issues have only received industry attention in recent years. Previously, I have done many related planning for LED driver quality issues. Recently, a South Airlines sister used the charging of an Apple mobile phone to make a phone call to be killed on the spot. For a time, the safety of this low-voltage power supply product has once again become the focus of hot discussion, also using DC power LED lighting driver. Will the power supply also kill people, how to ensure their safety? In addition, the driver's matching and non-uniform standards also hinder the development of the industry.
Understanding wine is more important than drinking
In 2008, China's main application of solar LED, LED full-color display and other LED applications, the output value has exceeded 45 billion yuan. From 2009 to 2010, during the period of vigorous development of the LED industry, China's investment in this field has not only increased significantly, but also achieved a certain degree of breakthrough in technology. In particular, the high-power LED driving power supply is driven by the demand of LED street lamps , showing a leaping growth trend. In the past two years, LEDs have “encroached†in the field of commercial lighting and home lighting with lightning speed. While the global LED lighting output value has increased, it will also drive the development of LED driver power.
LED lamps often have a "glass" heart, which is very easy to terminate life due to "myocardial infarction". According to the report of the special planning team of this newspaper, most of the application companies will produce power supply to ensure the quality and cost performance of the products. In addition to lighting an LED, LED driver power must overcome potential threats such as radiation, interference to the power grid, and failures in unexpected situations. This requires strict implementation by the enterprise. Various standards, the product is rigorously tested and verified.
Before you can complete the LED business, you must understand the industry. However, some LED companies are following the pace of development of the LED industry with an optimistic attitude, and did not want to lead the industry forward. In order to do a good job in LED business, we must first understand why LED driver power supply, which is the "heart" of LED lamps, will have so many vicious price competition, homogenization, and product mismatch. The safety and matching of LED drivers has always been criticized. Why has it not been resolved?
Song Jun, sales manager of Jinyu Technology Power Division, said that there is no unified standard for measuring LED power products, and many people are doing it. In addition, the power supply is not versatile, that is, the matching, the matching of the lamp and the power source refers to the matching of the lamp wattage and the current, and the lamp will not have a problem if it is matched strictly according to the standard.
