China's LED industry started in the 1970s. After more than 30 years of development, China's LED industry has initially formed a relatively complete industry including LED epitaxial wafer production, LED chip preparation, LED chip packaging and LED product application. chain. Among LED products, LED lighting has become a global trend with its advantages of energy saving and environmental protection. In recent years, with the support of national policies, the market 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.
LED drive power industry still has many problems, such as market chaos, disorderly competition, serious product homogeneity, overcapacity, etc., which have led to the rapid development expected in the past few years, and there has been an "accident." In fact, the development of an industry will have some unfavorable factors, but regardless of the current situation, the development prospects of the LED driver power industry will soon be tested.
1. Analysis of the market status of LED drive power
Due to LED lighting, energy saving, environmental protection, obvious advantages, are actively promoting the development of the global LED lighting industry forward. While the global LED lighting output value has increased, it has actually driven the development of the LED driver power industry.
1.1LED lighting drives the rapid development of LED power supply
With the continuous breakthrough of LED industry technology, its price decline, application field expansion and penetration rate increase, the LED product market is increasingly open.
From a global perspective, LED lights have become a global trend. Countries around the world have formulated relevant support policies for LED lighting and actively promoted the development of the LED lighting industry. It is reported that in the developed regions such as Europe, America, Japan and South Korea, LED lights have been basically popularized. From the domestic point of view, in 2008, China's LED application products, such as streetlights, solar LEDs, LED full-color display devices, landscape lighting, consumer electronic backlights, etc., have been mainly used in China. The output value has exceeded RMB 45 billion. 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.
According to GIL market survey statistics, in 2011, China produced 680,000 LED street lamps (excluding tunnel lights), an increase of 58%, of which LED street lights installed 530,000 ä¸ (excluding tunnel lights), an increase of 51.4. If the installation of tunnel lights is 190,000 baht, the total amount of high-power LED power supply for LED streetlight installation last year exceeded 700,000 units. If the price is 1000-2000 yuan per ton, the market size is 1.050 billion yuan. about. Based on this calculation, coupled with the installation of high-power LED power supplies such as subway lighting, underground parking lot lighting and gas stations, the overall market size in 2011 was about 1.3 billion yuan.
It has been suggested that 2012 is a key year for the development of LED lighting. Relevant research institutes analyzed that after the EU completely banned the sale of incandescent lamps this year, the global demand for LED bulbs will increase significantly from 596 million in 2011 to 2.5 billion in 2013. In addition to ordinary home lighting, the use of LED lights has been continuously extended in other areas. According to research by third-party survey agencies, by 2020, in the market of car headlights and daytime running lights, global LED lights accounted for The ratio will increase from 13 in 2011 to 34. The agency analyzed that in 2012, the global LED architectural lighting market will also exceed 3 billion US dollars, accounting for about 29% of the overall LED lighting market.
At the same time as the development of LED lighting, it will inevitably lead to the development of other LED industries such as LED drive power. Relevant departments expect that the number of LED drive power sources in China will reach 7 million units in 2013, and the market scale will be expanded to 1.75 billion.

1.2 Current status of LED driver power supply industry
Many people believe that although the current development of the LED industry is unstable, LED is definitely the direction of future development, so most companies are following the pace of development of the LED industry with an optimistic attitude, instead of going ahead and doing the LED industry era. The tide of the children led the LED industry to advance. From this, we can understand why there are so many vicious price competitions, homogenization, and mixed products in the LED driver power industry.
The director of the technical department of Yuan Yuxiang of Guangzhou Jiufo Electric Co., Ltd. said: "There is no uniform product index for LED power supply, and the product is overproduced. Our country calls this production a 'float bee'."
"At present, there is no unified standard for measuring LED power products, and many people do it indiscriminately." General Manager Zhang Yimin of Tianxia Ming Power Co., Ltd., which mainly targets commercial lighting power, put forward a "protest" on the lack of uniform standards for products.
Mr. Shao Geliang of Tiancun Enterprise Management Co., Ltd. expressed concern about the bad phenomenon of LED power supply. He said that the technology of LED power supply is not difficult. Anyone can do it. When doing it, we must pay attention to one problem, that is, the product quality is very poor and the price is very high. Low, this will cause many problems in the reliability and life of the power supply.
It is true that because the technical threshold of the LED power industry is not high, all walks of life are flooding in at a low price, which leads to market chaos, product specifications are not uniform, the industry does not form normative standards, vicious price competition, etc. The problem arises, and the ultimate hazard is that major power supply manufacturers have not been able to develop and produce higher quality products. Therefore, many people have called on the government or industry to formulate relevant standards as soon as possible, maintain order, and suppress the spread of malignant conditions, so that the power industry can develop healthily and steadily.
In the development of LED power supply, the modularization and intelligence of LED power supply has also caused a lot of heated discussion. 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.
For the problem of modularity and intelligence, it is the views of each family. Zhang Yimin, general manager of Tianxiaming Power Co., Ltd., which focuses on commercial lighting power supply, said that the cost of LED power supply will be lower after modularization, and intelligence can meet people's living needs, such as dimming and temperature regulation. General Manager Chen of Skyworth Lighting, which deals with indoor and outdoor lighting, said that modularity and intelligence are a trend in general lighting, and that this development in the future is good for the entire LED lighting. Just like a mobile phone charger, if you can use one, it's very good to change the control. After the intelligence, the advantages of LED can be better.
Mr. Wu Xiaochun of Tianxiaming Technology said that the modularization is mainly for large-scale street lamps, tunnel lights, etc., and these lamps are mainly used in hotels, highways, etc., so there is a certain advantage for commercial LED lighting, but the advantages of civil lighting are not obvious. . When asked about the impact on the LED power industry, Wu Xiaochun said that the impact on the entire industry is not too big, because it is mainly used in some special occasions, there are not many places to use, the real use is more households.
Director Yuan of Jiufo Electric Co., Ltd. believes that the current significance of China's intelligence is not great, because the contemporary living standards in China have not reached a certain height, and intelligence is very impractical. If it is a large hotel, a large hotel is smart or feasible, but it is not realistic to use intelligent lighting in general households and general public places, because its total cost is relatively expensive. But for modularity, he said: "Modularity is feasible, but national standardization can't keep up. Every enterprise has its own modular standards, and each application carrier is different. We can modularize as a large enterprise. Because the modularization cost is lower.
