Embodiment 1

[0040] like Figure 1-10 As shown in the figure, an LED explosion-proof lighting fixture for easy maintenance includes a lamp housing, and the lamp housing includes a lamp holder 2 for installing the LED explosion-proof lamp bead and a lampshade 1 mutually clamped with the lamp holder 2. The lamp holder 2 also There is a sliding cylinder 5 that is slidably sleeved with it, and a mounting seat 17 is slidably sleeved in the sliding cylinder 5. The mounting seat 17 is installed with an LED explosion-proof lamp bead and a transformer circuit that are electrically connected to each other. There is a first electromagnet 4 connected in series with the transformer circuit. The LED explosion-proof lamp beads and the first electromagnet 4 are installed on the output side of the transformer circuit. One end of the cylinder 5 corresponding to the first electromagnet 4 is also connected with a metal ring 6 that is adapted to the first electromagnet 4, and the inner wall of the lamp holder ...

Embodiment 2

[0042] The difference between this embodiment and the above-mentioned embodiment is that: refer to the appendix Figure 11 , S1 is the first electromagnet 4, S2 is the second electromagnet, and R is the resistance;

[0043] A second electromagnet connected in parallel with the first electromagnet 4 is also electrically connected to the external power supply line, and the input side and output side of the second electromagnet are respectively connected to the input side of the first electromagnet 4 and the output of the LED explosion-proof lamp bead. side, the second electromagnet is installed inside the lampshade 1 and corresponds to the position of the first electromagnet 4, and a switch capable of controlling the second electromagnet to be energized is also provided between the output side of the second electromagnet and the connection position of the external power supply line, The switch is installed on the lamp housing, and the strength of the magnetic field formed by eit...

Abstract

The invention relates to the field of explosion-proof lamps, and discloses an LED explosion-proof lighting fixture which is convenient for maintenance. A power-on loop can be formed, and the end of the sliding cylinder corresponding to the first electromagnet is also connected with a metal ring that matches the first electromagnet. The active spring can connect the sliding cylinder with the LED explosion-proof lamp beads when the first electromagnet is powered off. The transformer line is actively extended to the outside of the lamp holder. In the present invention, when the LED explosion-proof lamp bead is extinguished during use, there is no need to screw out the bearing member on which the LED explosion-proof lamp bead is installed, which saves maintenance time. Secondly, when the LED explosion-proof lamp bead is extinguished, it has independent judgment The function of the open circuit position can quickly determine whether it is the fault of the power-on line or the LED explosion-proof lamp bead. It is not necessary to disassemble the interior of the lamp and check one by one during maintenance, which further improves the maintenance efficiency.

Description

technical field [0001] The invention relates to the field of explosion-proof lamps, in particular to an LED explosion-proof lighting lamp which is convenient for maintenance. Background technique [0002] LED explosion-proof light is a kind of explosion-proof light. Its principle is the same as that of explosion-proof light, except that the light source is LED light source, which refers to various specific measures taken to prevent the ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. Measure light fixtures. [0003] Due to the special working environment of the explosion-proof lamp, for safety needs, the explosion-proof lamp needs to be disassembled regularly for maintenance and overhaul, while the operation of the existing explosion-proof lamp is cumbersome in the overhaul process. Installation and disassembly of dust gas LED explosion-proof lights, although convenient installation and removal of LED ex...
