Abstract: A LED string with stable voltage control receives a DC voltage. The LED string includes a plurality of LED apparatuses and a controller. The plurality of LED apparatuses sequentially receives a plurality of data signals externally provided by the controller through a signal path. The controller preferentially supplies power to the LED apparatus that directly receives the DC voltage via the positive voltage end, and the remaining LED apparatuses are supplied power sequentially. When the plurality of LED apparatuses does not receive the plurality of data signals, a bypass path is enabled to bypass the signal path so that no current flowing through the signal path; otherwise, when the plurality of LED apparatuses receives the plurality of data signals, the bypass path is disabled to make the plurality of data signals be transmitted through the signal path.
