The invention discloses a signal processing method and device for an infrared induction lighting lamp and the lighting lamp, and the method comprises the steps: obtaining a voltage reference signal and an infrared induction signal of an infrared inductor, and obtaining a difference value between the voltage reference signal and the infrared induction signal; when the difference value is smaller than a threshold value, dividing the difference value by a set value to obtain an adjustment threshold value; and obtaining a new voltage reference signal according to the sum of the voltage reference signal and the adjustment threshold. Compared with the prior art, drifting of the infrared induction signals influenced by the environment temperature is effectively restrained, the influence of background noise on the infrared induction signals is reduced, false triggering of the infrared induction lighting lamp is reduced, and the human body recognition accuracy of the infrared induction lightinglamp is improved. 本发明公开了
