Summary:The utility model discloses an LED (light-emitting diode) plant light-filling lamp with an adjustable illumination intensity. The LED plant light-filling lamp comprises a power supply, a human-computer interaction module, a central controller, a light-dimming unit and an LED lamp head group, wherein the human-computer interaction module and the power supply are connected with the central controller respectively; the light-dimming unit comprises a PWM (pulse-width modulation) modulator control module, a PWM modulator and a constant-current drive module which are sequentially connected; the PWM modulator control module is connected with the central controller; the constant-current drive module is connected with the LED lamp head group; and the PWM modulator is connected with the power supply. The PWM modulator is used for adjusting the constant-current drive module, and then adjusting the illumination intensity of each LED lamp head, so that an illumination intensity for plants is in the optimal range, and the
