Patent Description:
Due to the characteristics of LED light sources, conventional mains supply network voltages cannot be directly applied to LEDs. In order to meet the special voltage and current requirements of the LEDs, specially-designed voltage conversion equipment must be used, and then the LEDs can operate normally, so that LED lamps have power drivers different from those of traditional lamps.
