The invention discloses an explosion-proof type LED illuminating lamp with a magnetism switch, comprising a lamp, a lamp cover, an LED lamp positioned on the lower end of the lamp, a transparent lamp hood, a wiring board assembly and a power supply circuit board arranged in the lamp. The explosion-proof type LED illuminating lamp is characterized in that the wiring board assembly and the power supply circuit board are provided with two power electrodes; each power electrode is connected with the power supply circuit board by a reed switch; and the top of the lamp cover is provided with a magnetism switch capable of detachably controlling the connection/disconnection of the reed switch. In the explosion-proof type LED illuminating lamp with the magnetism switch, the reed switch is connected between the power electrode and the power supply circuit board; the magnetism switch, i.e., the detachable magnetic cock press plate assembly is applied to controlling the connection/disconnection of the power supply circuit board of the illuminating lamp and the power electrode. When the single illuminating lamp is replaced or maintained, the whole power supplying circuit for the illumination is not needed to be cut off, the continuous underground illumination is ensured, and the disadvantages of the traditional illuminating lamp is completely overcome. In addition, a power supply protecting hood is covered on the power electrode so that the power supply is effectively isolated, and the safety of the overhaul people and the maintaining people is ensured.
