The present invention discloses a functionally integrated induction lamp comprising a bottom case and a top case. A PCB having a light control circuit is arranged therebetween, which is provided with an induction sensor for detecting moving objects or ambient light signals to trigger the induction LED lamp for emitting light and an induction LED lamp connected to the circuit. A light guide plate enabling the light emitted by the induction LED lamp to come out and a sensor shield are arranged on the top case. An outer surface of the sensor shield is connected transitionally to an outer surface of the light guide plate smoothly to form a curved surface, which can greatly improve its appearance. Meanwhile, the sensor shield is a Fresnel lens with a smooth outer surface and an inner surface having concave and convex texture, greatly improving the induction to moving human bodies.
