  • Driver for LED and LED system
    Patent number: 11546977
    Abstract: A driver for a Light Emitting Diode (LED) comprises a main circuit of a Ringing Choke Converter (RCC), a driving circuit of the RCC, and a first adjustment module. The main circuit of the RCC comprises: an energy input terminal, an energy output terminal, and a control terminal. The energy input terminal is configured to receive an input voltage. The energy output terminal is coupled to the LED and configured to provide an output current to the LED. The control terminal is configured to receive a driving signal. The driving circuit comprises a driving signal output terminal coupled to the control terminal, and is configured to provide the driving signal to the main circuit via the driving signal output terminal. The first adjustment module is coupled between the energy input terminal and the driving signal output terminal, and is configured to adjust the driving signal according to the input voltage.
