Generally, the appearance of safety lights is very similar to the appearance of explosion -proof lights. Some industrial and mining enterprises often mistakenly use safety lights as explosion -proof lights in explosive places, which is very dangerous. Although the safety lamps are also equipped with glass lampshade and sealing ring, they can only prevent water and dust, but they cannot prevent the flawed gas drilling. If it reaches the explosion limit, it will cause explosion. The main difference between the two is that there are obvious explosion -proof electrical qualification certificates on explosion -proof lights. There are explosion -proof signs on the lamp shell, while general safety lights do not have these characteristics and signs.

Since the entering the 21st century, with the development of industrial development: the rapid development of oil, chemical, mining and other industries, the use of lighting lamps in production, warehousing, and rescue has become more and more extensive, with more and more varieties. At this time, how to prevent the occurrence of lighting lamps from accident explosion in explosive gas dangerous places is very important. Because ordinary lighting fixtures are inevitably produced in real estate or form a hot surface during work. Once they meet the explosive gas mixture at the production or rescue site, they will lead to the occurrence of explosion accidents. Essence Therefore, as a widely used lighting fixture, its explosion -proof technical problems have long aroused people's general attention and high attention, and in this case, explosion -proof lamps have emerged
