Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to an explosion-proof LED lamp. Background Art

[0002] With the advancement of science and technology, LED lamps have become a frequently used lighting fixture. Explosion-proof LED lamps are generally used in dangerous places where flammable gases and dust exist. They can prevent arcs, sparks, and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby meeting the explosion-proof requirements of lamps. With the rapid development of industries such as petroleum, chemical, and mining, explosion-proof LED lamps are increasingly used in production, warehousing, and rescue, and there are more and more varieties. However, explosion-proof LED lamps need to work for a long time. After long-term lighting, the internal temperature will increase, and the internal heat cannot be dissipated in time, which will affect the normal operation of the internal lamp board and the driving power supply, shortening the service life of the explosion-proof LED lamp. Sometimes the temperature is even too high, and spontaneous combustion and explosion will occur, resulting in poor performance. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Utility Model Content
