The explosion-proof performance of machine tool work lights is relative rather than absolute. Explosion proof work lights refer to lighting fixtures used on machine tool equipment that can prevent arcs, sparks, and high temperatures that may occur inside the lights from igniting combustible gases and dust in the surrounding environment, thereby meeting explosion-proof requirements. They are also known as explosion-proof lights or explosion-proof lighting fixtures. The so-called explosion-proof does not mean that the lamp itself can not explode, but to prevent unnecessary dangers due to its own reasons. Therefore, in the design and manufacturing process of the lamp, its own rationality and safety factor must be taken into consideration, so as not to let its own problems affect the safety of use. Especially in situations where there is a lot of dust and high manufacturing safety requirements, the use of explosion-proof lighting fixtures on machine tools is particularly important, as it not only protects oneself but also others< Br style="color: RGB (51, 51, 51); font family: Tahoma, Arabic, 'Microsoft Yahei';"/>
