Explosion-proof type LED illuminating lamp with magnetism switch

Abstract

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.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a flameproof LED lighting lamp with a magnetic control switch. The lighting fixture has a wide range of uses, and is especially suitable for illuminating the severe environment in underground coal mines. Background technique [0002] At present, the lighting lamps used in underground coal mines mostly use multiple lighting lamps connected in parallel in the lighting power network. Higher requirements are put forward for the lighting of underground lanes, tunneling and coal mining face. The main drawbacks that exist now are that when repairing and replacing individual lighting fixtures, it is often necessary to cut off the power of the entire lighting system underground, so that the underground lighting is completely lost, which seriously affects the mining construction and delays the construction period; in addition, due to the lack of safe and reliable isolation devices , When inspecting a...
