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. The newspaper has also made relevant plans for LED driver quality problems many times before. Recently, a South Air sister used the charging of an Apple mobile phone to make a call to death on the spot. For a time, the safety of this low-voltage power supply product has once again become the focus of hot discussion. 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". Most application companies will supply power 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.
Outsourced power supply or supporting production
Most people have a misconception that the LED driver power supply has a short lifetime and does not match the long life of the LED chip. This is not the case. In theory, the short life of the drive power supply is mainly due to the electrolytic capacitor inside the power supply. For every 10 °C rise in electrolytic capacitor temperature, the lifetime will be halved. When the electrolytic capacitor temperature is 105 ° C, even if the electrolytic capacitor of better quality, the life can only be maintained for 8000 hours. It can be seen that heat dissipation is a key point. However, the market is still full of driving power for cutting corners. According to the data compiled by the special planning team of this newspaper, 70% of the enterprises will supply power, and more than half of the dealers will care about the quality of the drive.
In the development of LED power supply, the modularization and intelligence of LED power supply has also caused a lot of heated discussion. According to the reporter's visit, there are not many enterprises that have launched intelligent lighting products in various supermarkets. Many exhibitors at this year's exhibitions have exhibited intelligent masterpieces. In fact, modularization refers to packaging with standardization and industrialization, and through the innovation of technology and process to reduce costs and achieve large-scale manufacturing. Intelligentization generally means that the brightness of the luminaire can be adjusted and the light can be turned off.
Different people have different opinions on how to purchase drivers. Some companies say that foreign LED driver power supply research is relatively thorough, and each product has a good match, so the stability of international brand power supply is better, but otherwise, other The aspects are similar. Some people think that it is not arbitrarily considered that international brands are good, and domestic brands are not good. The key lies in the company's understanding and control of quality. Only by controlling the quality can the basic standards be met. Due to the high price of international brands, domestic suppliers have a competitive advantage in terms of price, but suppliers must have a certain understanding of quality, especially quality awareness.
He Weiyong, general manager of Enwei West's optoelectronics marketing department, said that Enwei West's power supply is mainly outsourced at the end of this year. It will be produced independently at the end of this year. When purchasing power, it mainly depends on the stability and consistency of the power supply. Specifically, the ratio of the magnetic material is required, mainly depending on whether the power supply maintains a constant current. He pointed out that domestic component companies are generally not willing to invest in improving products, so the products are still of traditional quality.
It is true that the LED driver power industry has been idealized in the initial stage of development. In reality, according to the current situation, it has to be acknowledged that the development of the industry is not stable. However, regardless of the current status of the LED driver power industry, its development direction is still the trend of the times, the "glass" heart will gradually become the "diamond" heart, with the development of the LED lighting industry and the constant regulation of the LED drive power market order, industry standards Will continue to standardize, product differentiation will continue to be obvious.
