Insufficient LED power driver

by:MOSO     2019-12-11
Reasons for insufficient LED driving power: (1) The production of LED lighting and related technicians do not know enough about the switching power supply, and the power supply can work normally, but some key assessments and electromagnetic compatibility considerations are not enough, there are still some hidden dangers; (2) Most of the LED power production is transformed from ordinary switching power supply to make LED power. The characteristics and use of LED are not enough; (3) There are almost no standards for LEDs, and most of them refer to standards for switching power supplies and electronic rectifiers; (4) Most LED power supplies are not uniform, so most of them are relatively small. If the purchase volume is small, the price is high, and the component suppliers are not very cooperative; (5) LED power supply stability: Wide voltage input, high temperature and low temperature work, over temperature, over voltage protection and other issues have not been solved one by one face the challenge First: improve life and extend the use of lamps. The overall life of the drive circuit, especially key components such as: the life of the capacitor at high temperatures directly affects the life of the power supply; Second: improve efficiency and improve the light efficiency of lamps. LED drivers should challenge higher conversion efficiency, especially when driving high-power LEDs, because all power that is not output as light is dissipated as heat, and the power conversion efficiency is too low, which affects the performance of LED energy saving ; Third: reduce costs and increase affordability. In applications with low power (1-5W), the proportion of the cost of constant current drive power is close to 1/3, which is close to the cost of the light source, which has affected the market promotion to a certain extent.
