The invention discloses an LED locating lamp. The LED locating lamp is controlled to be turned on and off according to RSSI values of wireless signals transmitted by a wireless signal receiving and transmitting terminal. The invention further discloses an intelligent lighting system based on the LED locating lamps. The intelligent lighting system comprises a gateway, an upper computer, the wireless signal receiving and transmitting terminal and the three or more LED locating lamps. The LED locating lamps calculate the RSSI values of the received wireless signals and transmit the RSSI values and geographic positions to the wireless signal receiving and transmitting terminal. The wireless signal receiving and transmitting terminal calculates the position of the wireless signal receiving and transmitting terminal through the RSSI values and transmits the position to the upper computer. The upper computer calculates a motion track of the wireless signal receiving and transmitting terminal and controls the LED locating lamps on the track to be turned on according to the motion track. The invention further discloses a control method of the intelligent lighting system based on the LED locating lamps.
