The invention relates to an intelligent lighting system and an induction device. The intelligent lighting system comprises a first lighting lamp, a second lighting lamp and the induction device, wherein the induction device comprises a first human body induction module and a second human body induction module; the first human body induction module is used for outputting a first starting signal to the first lighting lamp when detecting a human body within a first preset range; the second human body induction module is used for outputting a second starting signal to the second lighting lamp when detecting the human body within a second preset range, and outputting a second power-off signal to the second lighting lamp when detecting the human body again within the second preset range after outputting the second starting signal; the first human body induction module is also used for outputting a second power-off signal to the second lighting lamp within the first preset range when the human body is not detected within the second preset range after the second human body induction module outputs the second starting signal; and the first preset range is greater than the second preset range. The intelligent lighting system has the characteristics that the electric energy is saved and the usage experience is good.
