LED string
First Claim
1. An LED string comprising:
- a power plug configured for connecting with a power source to power the LED string;
one or more LED sockets configured for electrically connecting with the power plug;
one or more LEDs configured for being installed on and electrically connecting with the one or more LED sockets; and
a control module configured for being electrically connected with one of the one or more LED sockets;
wherein the control module includes a control circuit, an input terminal, an output terminal, the control circuit electrically connects with one of the one or more LED sockets via the input terminal and the output terminal and controls a current flowing through the LED string to change from a first value to a second value, thereby controlling the LED string to light;
wherein the control circuit comprises an oscillating circuit, a resistance component and capacitance component network (RC) circuit, and a field effect transistor, the oscillating circuit outputs a square wave signal, the RC circuit converts the square signal to a triangle wave signal which is used to control the field effect transistor to turn on and off, the field effect transistor comprises a drain electrode and a source electrode and a gate electrode, the drain electrode and the source electrode are correspondingly connected with the input terminal and the output terminal of the control module, and the gate electrode is connected with the RC circuit.
