challenges of LED light driver

challenges of LED light driver:

First: improve the life span and extend the lamp life. 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 effect of lamps. LED drivers should challenge higher conversion efficiency, especially when driving high-power LEDs, because all power not used as light output is dissipated as heat, and the power conversion efficiency is too low, which affects the energy-saving effect of LEDs. ;

Third: reduce costs and improve purchaseability. In applications with low power (1-5W), the cost of the constant current drive power supply accounts for close to 1/3, which is close to the cost of the light source, which affects the market promotion to a certain extent.
