The lampshade is located below the explosion-proof lamp housing, and a light-transmitting cover is disposed inside the lampshade. A flange is installed on the light-transmitting cover, and the light-transmitting cover and the flange are threaded together. A light-transmitting rubber ring is disposed between the flange and the light-transmitting cover. The flange is fixedly connected to the explosion-proof lamp housing, and the lampshade and the flange are connected by screws. A hanging device is disposed above the explosion-proof lamp. The power supply cavity is located above the explosion-proof lamp housing and is fixedly connected to the explosion-proof lamp housing. A power board is disposed inside the power supply cavity. The junction box is located above the power supply cavity and is fixedly connected to the power supply cavity. This novel LED explosion-proof lamp has a simple structure, is easy to use, and is conducive to promotion; it has good explosion-proof performance, saves energy, and has high safety performance; it also has advantages such as good heat dissipation and long LED lamp life.

[0004] In summary, the existing system has many drawbacks, which are summarized as follows:
