The invention discloses an intelligent illumination system, and particularly relates to an intelligent illumination system which integrates voice control, manual control and automatic light intensitycontrol. The intelligent illumination system consists of a control box, an acquisition box and an LED lamp, and is formed by a voice recognition module, a voice synthesis module, a Wifi module, a GSMmodule, a clock module, a light intensity acquisition module, an alarm module, a voltage sensor module, a current sensor module and an LED lamp bank by taking a data processing module as a processingcenter. On the basis of inheriting the current illumination system control manner, the intelligent illumination system is provided with a voice control function, an intelligent overhauling function, an automatic dimming function and a remote control function, so that the illumination system control manner is more diversified, the illumination management is more scientific and intelligent, the phenomenon that the current illumination systems do not save electric energy obviously and even waste electric energy is solved, and the problem that the current illumination systems are not high in intelligence degree is solved.
