Explosion-proof lights and lampshades should be able to automatically cut off the power before they are opened. However, due to the complexity of setting up the interlocking device, it is difficult to implement. Therefore, most lamps and lanterns only have warning signs such as “No live-on†on the obvious part of the enclosure. Because the surface temperature of the bulb is still high after power off, if you open the lampshade immediately, there is still the danger of igniting the explosive gas mixture (mainly flameproof structure). Therefore, the surface temperature of the incandescent lamp, high pressure mercury lamp, and high pressure sodium lamp are high. , but also quickly open the lid of the luminaire to pay attention to this. The use of more CeY-1 explosion-proof fluorescent lamps has an interlocking mechanism that opens and closes the power supply, providing convenience and safety for maintenance work. Because the fluorescent lamp is a cold light source lamp, there is no surface high temperature, and the lid can be opened immediately after the power is turned off.
