As one of the core components of LED products, the driving power supply has always occupied a large proportion in the cost structure of LED lamps. According to relevant data, the cost ratio of power accessories in general-purpose lamps has been increased to 10%-20%, and the cost of non-universal lamps is as high as 20%-30%.
With the gradual decline in the price of LED lamp beads and whole lamps, the high cost of power supply has been further amplified, and many LED application companies have adopted lower-cost power solutions under pressure. In the face of the change of market winds, power supply manufacturers only see the wind and rudder, relying on low-cost power solutions in exchange for price advantages, to attract customers to purchase.
Before the collapse of Zhongshan Xiongji Lighting , it was the low-cost strategy to ship its driving power to the LED finished lamp enterprises, which occupied a considerable market share, and also reflected the demand for low-cost power in the LED application market. The amount is gradually rising.
"The impact of the boss's running on the LED market in Guzhen is very big. Many LED factories that originally bought Xiongji Power have to buy the same quality power supply. The unit price will be two or three cents higher." One manufacturer Said to reporters. He said that the failure of Xiong Kee brought different degrees of harm to both its customers and IC suppliers. A sudden change in the market will also lead to more serious price killings, and the holes that are smashed by the smashing will be filled by other power supply manufacturers.
"Price is the biggest factor affecting the development of LED power supply , it dominates the future development direction of LED power supply." Tian Guohui, general manager of Shenzhen Giant Energy 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 the power supply factory to repeatedly adjust the cost of the product.
Under the influence of this environment, some IC factories began to speculate on the concept of “de-powering†to reduce power components to achieve cost reduction. At present, manufacturers on the market have reduced the power cost of 3W bulbs to 6 cents based on this technology.
"The de-energization of LED lighting products is an inevitable development trend." Liu Yiquan, general manager of Kabo Sitong, believes that removing the external power supply can bring more design space to LED products, and the products are more diverse. However, this solution has very high requirements for chip and heat dissipation design. Whether it can be realized or not depends on the development of technologies such as chip and heat dissipation.
Tian Guohui, who is mainly promoting the miniaturization and high efficiency of LED power supply, is skeptical about the "de-energization" technology. He said that this technology is still very flawed at present and the market prospects are uncertain. In fact, the practice of reducing the cost of components in exchange for cost is having a negative effect.
According to an industry insider, some IC companies have made some unreliable solutions to meet the requirements of “high reliability, low cost, and good sales†proposed by application companies to minimize the use of power peripheral components. Provided to customers.
"There are many LED factories that don't have power engineers. They don't ask technicians. It's not because they don't have money, but they don't feel that it's unnecessary. I said that all the IC factories are going to do it. I ask engineers to waste money. I don't know if they made a mistake. A big mistake, because the solutions provided by IC factories are not necessarily suitable for them. Manufacturing processes, raw material testing, etc. are all required by professional people, and those companies that do not plan to do it are impossible to do the process and inspection. The person finally said.
