Disclosed are an alternating-current high-voltage multi-segment partitioned light source driving device and method thereof. The device comprises a power source, a signal control module, n number of segment constant-current drive modules, and n number of MOS tubes and n segments of LED lights, n being a natural number greater than or equal to 2; the signal control module is provided with an input end and n number of output ends; the power source separately connects electrically to the input end of the signal control module and the n segments of LED lights; the constant-current drive modules of the segments are correspondingly connected in series to the MOS tubes; the first to the m-th segments of the LED lights are serially connected and then electrically connected to the m-th MOS tube, m being a natural number smaller than or equal to n. The present invention divides the LED light source into multiple segments according to the power of the conducting zone and the LED light source distribution requirement, such that more segments provide more light, thereby maximizing the conducting zone, minimizing the no-light-consumption zone, enhancing the power source efficiency, extending the LED light service life, and improving the electricity provision efficiency of power plants. |
