Abstract
An LED light string has a plug with two front diodes, an extension socket with two rear diodes, multiple LED units connected between the plug and the extension socket, and multiple intermediate diodes connected to the LED units. The intermediate diodes, the two front diodes and the two rear diodes are connected to form multiple bridge rectifiers. The multiple bridge rectifiers are connected to an AC voltage in parallel and drive the LED units, respectively.
