The invention relates to an induction lamp. The induction lamp comprises a sensor module, a drive plate, a light source plate, a gear switch connector, a rotation component and a Fresnel lens. The sensor module is used for measuring incidence infrared light irradiating to the sensor module and generating triggering signals when the measured infrared light meets the preset condition. The drive plate is used for controlling the light source plate to emit light after the triggering signals sent by the sensor module are received. The gear switch connector is used for controlling and adjusting the time duration of a delay switch. The rotation component is matched with the gear switch connector to adjust the gear switch connector. The Fresnel lens is used for covering the sensor module and gathering the incidence infrared light, and is matched with the rotation component. Through the arrangement of the gear switch connector, the rotation component matched with the gear switch connector and the Fresnel lens, the delay turn-off time of the induction lamp is adjusted so that the induction lamp can adapt to needs of different occasions and people, and the situation of energy waste is reduced under the situation that usage is guaranteed.
