Time-division multiple-path constant current driving LED lamp

A time-division multiple-path constant current driving LED lamp comprises a plurality of LED particles and a driving power supply used for driving the LED particles to emit light, wherein the LED particles are grouped into a plurality of LED groups, and each LED group comprises at least one LED particle. The time-division multiple-path constant-current driving LED lamp is characterized in that the driving power supply comprises a constant current conversion module capable of outputting constant current and a scheduling module connected to an output end of the constant current conversion module; the scheduling module comprises a controller used for generating a plurality of PWM signals and a plurality of switching-on/off devices which are controlled by the PWM signals generated by the controller and can directly drive the LED groups; and a product of a current value of the output current of the constant current conversion module and a duty ratio of the PWM signals input into the switching-on/off devices is the value of driving current required by the LED groups. By adopting only one constant current unit, the production cost is greatly reduced; and compared with a conventional power supply with a plurality of constant current units, electric signal interference between adjacent two constant current units is reduced and the output current of the power supply is purer by adopting only one constant current unit.
