The invention provides an intelligent lamp, which includes a voltage and current conversion circuit, a light induction detection circuit, an LED light sensor and an LED light emitting circuit. The LED light sensor outputs a light brightness change signal to the light induction detection circuit by sensing the change in the light brightness of the LED light emitting circuit. The light induction detection circuit generates a light adjustment command according to the light brightness change signal, and adjusts the light emitting brightness and/or color temperature of the LED light emitting circuit. Whether an adjustment is required for the brightness and/or color temperature of the LED light emitting circuit is judged without detecting the current or the amount of change in the current in the intelligent lamp. The misjudgment caused by interference of a surrounding circuit to the voltage or current of the circuit in the intelligent lamp is avoided, and the light switching accuracy of the intelligent lamp is effectively increased.
