A mine explosion-proof led roadway light

Abstract

The invention relates to the technical field of roadway lighting lamps and aims to provide a mining flameproof type LED roadway lamp comprising a shell, an LED lighting module and a circuit module; aconnecting base is arranged at one end of the back face of the shell, and a connecting channel in communication with the inner cavity of the shell towards the shell direction is arranged in the connecting base; a male plug-in piece used for connecting cables is slidably connected in the connecting channel towards the direction of the inner cavity of the shell, and a female socket capable of beingplugged and connected in the sliding direction by the male plug-in piece is fixedly connected in the shell; and a controller used for controlling disconnection of the male plug-in piece and the femalesocket is arranged on the connecting base; the male plug-in piece is connected with a cable, and the male plug-in piece and the female socket are disconnected through the control device, so that thedisconnection of the circuit is carried out inside the connecting base, the generated electric arc is prevented from being directly in contact with the outside, and the power-off safety is improved; asingle mining flameproof type LED roadway lamp can be directly subjected to work of light source replacement or maintenance and the like after power failure, and the power supply is not required to be cut off.

Description

technical field [0001] The invention relates to the technical field of roadway lighting lamps, in particular to a mine explosion-proof LED roadway lamp. Background technique [0002] Mine explosion-proof LED roadway light adopts the unique design of separate cavity for power supply, light source and wiring, which makes the whole light not only beautiful in appearance and easy to install, but also greatly improves the performance of explosion-proof, impact resistance, vibration resistance and heat resistance of the lamp. It is suitable for places where there is a risk of gas (methane) coal dust explosion in coal mines, and it can also be used in infrastructure mine tunnels and chambers with large water splashes, and the power supply must be cut off before replacing the light source and disassembling the lamp. [0003] At present, the Chinese patent document with the authorized announcement number CN102798058B in the prior art discloses a mine explosion-proof LED roadway lamp,...

AI Technical Summary

Problems solved by technology

[0004] Before replacing the light source and disassembling the lamp, the mining explosion-proof LED roadway light in the above patent document needs to cut off the power supply, or pull out the cable from the cable lead-in device; and cutting off the power supply will cause the same power supply to be connected Multiple roadway lights in the tunnel are extinguished at the same time, which affects the construction progress in some areas; and if the cable is pulled out of the cable lead-in device too quickly, it is easy to cause an arc at the disconnected part of the cable, which has the risk of gas and coal dust explosion in the coal mine. place is very dangerous
