Technical Field

[0001] This utility model relates to the field of explosion-proof work light technology, specifically an LED explosion-proof work light. Background Technology

[0002] LED explosion-proof lighting fixtures are similar to other explosion-proof lighting fixtures, but differ in that they use LEDs as the light source. These fixtures are designed to prevent the ignition of surrounding explosive mixtures such as explosive gas atmospheres, explosive dust atmospheres, and methane gases, employing various specific measures. Because LEDs are solid-state cold light sources, they possess advantages such as high electro-optical conversion efficiency, low heat generation, low power consumption, safe low operating voltage, and long service life. Therefore, high-power white LEDs are an ideal light source for explosion-proof lighting fixtures, especially portable explosion-proof lighting fixtures.

The lamp head mounting base is detachably connected to a glass pressure ring distributed outside the opening end of the lamp source mounting cavity and in contact with the connecting ring body. The connecting ring body is clearance-fitted with the lamp source mounting cavity and is distributed along the axial direction of the lamp head body between the lamp source mounting cavity and the glass pressure ring. Several sets of disassembly and assembly screws are evenly distributed on the outer circumference of the glass pressure ring. The lamp head mounting base is provided with connecting threaded holes corresponding to each set of disassembly and assembly screws. A sealing mechanism is provided between the lamp source mounting cavity and the top cover.
