As one of the core components of LED products, driving power supplies have always occupied a large proportion in the cost structure of LED lamps. According to relevant data, the current cost proportion of power supply accessories in general-purpose lamps has increased to 10%-20%, and the cost proportion of non-universal lamps is as high as about 20%-30%.
As the prices of LED lamp beads and entire lamps gradually decline, the high cost of power supplies has been further amplified. Many LED application companies have chosen lower-priced power supply solutions under pressure. Faced with the change in market trends, power supply manufacturers have no choice but to adapt to the trend and rely on low-cost power supply solutions in exchange for price advantages to attract customers to purchase.
Before Zhongshan Xiongji Lighting closed down, it used a low-price strategy to ship a large number of its driving power supplies to LED finished lamp companies, and thus occupied a considerable market share. It also reflected the demand for low-priced power supplies in the LED application market. The volume is gradually increasing.
"The departure of Boss Xiongji has had a great impact on the LED market in Guzhen. Many LED factories that originally bought Xiongji power supplies had to buy power supplies of the same quality, and the unit price would be two to three cents higher." A manufacturer told reporters. He said that the collapse of Xiongji has brought varying degrees of harm to its customers and IC suppliers. Sudden changes in the market will also bring about more serious price competition, and the holes pierced by Xiongji will be filled by other power supply manufacturers.
"Price is the biggest factor affecting the development of LED power supplies, and it dominates the future development direction of LED power supplies." Tian Guohui, general manager of Shenzhen Juneng Weiye, told reporters. He believes that with the overall decline in the price of LED lamps, the price pressure on power supply accessories is also increasing, forcing power supply manufacturers to repeatedly adjust the cost plan of their products.
Under the influence of this environment, some IC manufacturers have begun to hype the concept of "de-power supply" to reduce power supply components to achieve the purpose of reducing costs. Currently, there are manufacturers on the market that use this technology to reduce the power supply cost of 3W bulbs to 60 cents.
"De-powering LED lighting products is an inevitable development trend." Removing external power supplies can bring greater styling and design space to LED products and make the products more diverse. However, this solution has very high requirements for chip and heat dissipation design. Whether it can be truly realized still depends on the development of chip and heat dissipation technologies.
Juxin Deyuan Technology, which mainly promotes miniaturization and high efficiency of LED power supplies, is skeptical about the "de-power supply" technology. He said that this technology still has many flaws and the market prospect is unclear. In fact, the practice of reducing components in exchange for cost advantages is having negative effects.
According to an industry insider told reporters, in order to meet the so-called "high reliability, low cost, good marketability" requirements put forward by application companies, some IC companies have minimized the use of peripheral components in the power supply and made some unreliable solutions. provided to customers.
"There are many LED factories that do not have power engineers. They do not hire technical personnel, not because they have no money, but because they feel that it is not necessary. They say that the IC factory can do it all, and hiring engineers themselves is a waste of money. Little do they know that they have committed a crime This is a big mistake, because the solutions provided by IC factories are not necessarily suitable for them. The manufacturing process, raw material testing, etc. all need to be checked by professionals, and it is impossible for those companies that provide solutions to do process and incoming material testing for them. "The person finally said.
