The invention belongs to the technical field of computer control, which relates to a stepless dimming LED multi-path drive constant-current system which is remotely controlled by a computer and a stepless dimming LED multi-path drive constant-current source which is remotely controlled by the computer. The system comprises a remote control terminal, a constant-current source and N LEDs or N groups of LEDs, wherein the constant-current source comprises a network connection device, a microprocessor, a working power supply and N LED drivers. The N LED drivers drive the N LEDs or the N groups of LEDs, the remote control terminal transmits a control signal to the microprocessor by the network connection device, the microprocessor receives the control signal and controls the LED drivers to work, and the LED constant-current drivers regulate constant direct current obtained from the working power supply into current which is matched with the control signal and output to the LEDs. The invention not only can control the working state of each LED or each group of LEDs but also can obtain the timely working states of the N LEDs or the N groups of LEDs.
