Analysis of current situation and development trend of LED power supply market

In the current wave of rapid development of technology, the LED lighting industry has shown a rapid development trend with its significant advantages such as energy conservation and environmental protection. The closely related LED power supply market is also like a ignited flame, rapidly spreading and expanding. Traditional power supply manufacturers keenly seized this market opportunity and expanded their business into the LED power supply field and launched a series of related products; at the same time, many companies with entrepreneurial dreams have sprung up and poured into this emerging market. However, as power supply technology is still in the stage of continuous exploration and improvement, relevant industry standards have not yet been issued in time, causing frequent chaos in the entire market and urgent need of regulation and integration. Some industry experts predict that in the future, the LED power supply market will eventually move towards a pattern dominated by a few industry giants, and innovation in marketing strategies and excellent product quality will become the key for companies to stand out in the fierce competition.

Market expansion triggers price wars

Looking back at the LED industry in 2010, it can be said that opportunities and challenges coexist, with mixed joys and sorrows. The market size continues to expand at an alarming rate, but not all participants can get a piece of this industry wave. In the segment, most companies engaged in street light production face profit difficulties, while companies focusing on the production of LED tunnel lights can only maintain basic operations and earn meager profits. In the field of commercial lighting, those companies with strong foreign trade capabilities have achieved good returns; chip companies have ushered in the spring of development. Many domestic chip companies that had been in a state of loss for a long time have successfully turned losses into profits this year. Packaging companies have also gained a lot. Throughout 2010, the market demand for LED modules was strong, and the supply of products exceeded demand.
LED power supply companies also generally achieved profits during the year, but unlike the situation where the LED chip market exceeds supply, the supply in the LED power supply market is relatively sufficient. This is mainly due to the fact that LED power supply technology essentially belongs to the traditional electronics industry. After years of development, my country's electronics industry has strong manufacturing capabilities. However, shortly after the emergence of the industry, a fierce price war broke out in the market, especially in the field of low-power power supplies, where price competition was particularly fierce. At present, the price of low-power LED power supplies is very transparent. Taking LED fluorescent lamp power supplies as an example, the price is usually maintained at around 245 yuan.
In contrast, the high-power LED power supply market still maintains a high profit margin. On the one hand, the technical threshold of high-power LED power supplies is high, and research and development and production require a large amount of capital investment; on the other hand, high-power LED power supplies are mainly used in street lights, tunnel lights and other fields, and these lamps are currently mostly used in government demonstration projects. In order to ensure the best results of the demonstration project, street lamp manufacturers strive to optimize the selection of product accessories (at least when the sample lamp is produced), which undoubtedly puts forward higher product requirements for the power supply factory, thus promoting the profit of high-power LED power supply. Improvement.
From the perspective of market performance, major LED power supply manufacturers such as Mingwei, Infit, and Moshuo achieved several times growth in their business in 2010, fully demonstrating their competitive advantages and development potential in the market.

Shortcomings in power supply technology are highlighted

At present, the quality problems of LED power supplies for indoor lighting occur frequently, and the stability is worrying. According to statistics, one to two out of every ten indoor LED power products will flash after a period of use. Hua Guichao, chairman of Infit, pointed out that during the product design process, some small power supply manufacturers only satisfy the basic requirements for the power supply to work normally, but ignore the complexity of the actual working environment. However, in practical applications, LED street lights often need to operate stably in harsh environments such as high temperature, humidity, and severe cold, which undoubtedly poses higher challenges to the adaptability and reliability of the power supply.
Xu Changchun of Northern Huihua also said that although the entry threshold for the LED power supply industry is relatively low, it is not easy to produce high-quality products. A high-quality LED power supply product needs to be strictly controlled in multiple aspects such as R & D and design, raw material procurement and manufacturing. Sometimes, even if the sample test passes successfully, batch quality problems may still arise during large-scale production. He also mentioned in particular that unlike some Guangdong companies that use cheap components quoted by the catty, Northern Huihua insists on selecting high-quality components quoted by the piece to ensure product quality.
It is worth noting that although most LED lamp failures stem from power supply problems, it is not objective to blame the power supply company entirely. Xu Liancheng, an expert on LED street lights, emphasized that power failure is the result of a combination of multiple factors, among which the unreasonable design of lighting companies is also one of the important reasons for the problem. Therefore, in order to effectively reduce the power failure rate, power supply companies and lighting companies must strengthen communication and cooperation, and jointly overcome technical problems through collaborative innovation.
In recent years, with the continuous advancement of LED light source product packaging technology and heat dissipation technology, the stability of the light source has been significantly improved. Problems such as light fading and color drift are mainly caused by unreasonable heat dissipation design. Direct necrosis of the light source has become extremely rare. In contrast, the power supply problem is more prominent. Once a failure occurs, the lamp will often go out directly or flash frequently, and the frequency of occurrence is high. In addition, the lack of industry standards is also one of the important factors restricting the development of the LED industry. Due to the lack of unified standards and specifications, manufacturers face many difficulties in product production, quality inspection and after-sales service, and maintenance costs have increased significantly, which has hindered the healthy development of the entire industry to a certain extent.
