The invention provides an intelligent lamp with a function of detecting indoor harmful gas. The intelligent lamp includes an intelligent lamp illumination main body, a harmful gas detecting module, asound and light alarming module, a communication alarming module, a linkage processing module and a controller module, wherein the communication alarming module is used for achieving that a user monitors the indoor situation through a mobile phone client; the linkage processing module is used for pre-starting an exhaust fan to work when in the danger to timely exhaust the indoor harmful gas; and the controller module is used for coordinating the operation of the modules. The harmful gas detecting module detects the concentrations of smoke and combustible gas in the indoor environment and sendsdetection results to the controller module. When danger occurs, the controller module drives the sound and light alarming module to work and meanwhile starts the exhaust fan to exhaust the indoor harmful gas timely; and in addition, a monitoring signal is also sent to a monitoring unit of the mobile phone client of the user. According to the intelligent lamp with the function of detecting the indoor harmful gas, the harmful gas detecting device and the intelligent lamp are combined, wiring is saved, and the occurrence of family gas poisoning, fire disaster and the like can be effectively avoided.
