The lampshade 23 is made of transparent material to ensure that the light is emitted and reduce light loss.

[0073] The protection frame 30 is made of metal material, is disposed outside the lampshade 23 , and is connected to the lamp housing 10 to protect the lampshade 23 .

[0074] That is, the protection frame 30 can be enclosed on the outside of the lampshade 23, thereby preventing the impact of other objects. In this way, the lampshade 23 can be protected from collision, thereby increasing the service life of the lampshade 23 in harsh environments such as mining areas.

[0075] The omnidirectional mining LED floodlight explosion-proof lamp provided by the embodiment of the utility model has a simple structure and a wide irradiation range. At the same time, a protective frame is provided to protect the lamp to prevent the lamp from being subjected to physical impact.

[0079] Preferably, a two-component organic potting glue is filled between the lampshade 23 and the lamp holder 21 .

[0080] That is, the lower shell 11 is composed of a bottom plate 111 and an annular shell 112, and the upper end is open. There is a certain space inside the lower shell 111 to install relevant electronic components. Then the upper cover 12 is covered on the annular shell 112, and the upper annular sealing explosion-proof ring 13 is used to seal the electronic components thoroughly, so that the electronic components are isolated from external air and explosive dust, thereby achieving a better explosion-proof effect. Threaded holes are provided on the upper ear seat 121 and the lower ear seat 1121 to facilitate the insertion of screws. In this way, the lower shell 11 and the lower cover can be locked and fixed by screws and kept in a locked state. The fixing effect is good, which is conducive to the sealing of the lower shell 11 and the upper cover 12, and is convenient for disassembly and subsequent disassembly.

[0081] Similarly, the lampshade 23 and the lamp holder 21 are filled with a two-component organic potting glue 231, which can make the lampshade and the lamp housing sealed and connected, thereby isolating the floodlight head 22 from explosive dust in the external air, and further sealing the floodlight head 22, with a high explosion-proof grade, which is beneficial to improving the safety of the lamp.

[0082] Advantageously, in an embodiment of the present invention, a hanging piece 122 is disposed on the upper surface of the upper cover 12 , and the hanging piece 122 is used to hang the lamp housing 10 .

[0083] The hanging member 122 is a ring-shaped structure, and the lamp housing 10 can be hung on the hook-shaped structure, so that the lamp can be hung and fixed easily.

[0084] Advantageously, in another embodiment of the present invention, two wire connecting seats 1122 are oppositely disposed on the outer side wall of the annular shell 112 , and the two wire connecting seats 1122 are used to connect wires.

[0085] The wire connection seat 1122 is connected to the internal space of the annular shell 112, and an internal thread is provided on the wire connection seat 1122. In this way, after the wire is passed from the wire connection seat 1122 to the inside of the annular shell 112 and connected to the relevant electronic components, it can be threadedly connected to the wire connection seat 1122 through the connecting structure on the wire to fix the wire and prevent the wire from falling off the electronic component after being pulled by external force.

[0088] The base 211 is an inverted regular polygonal pyramid structure, and a lamp board 221 is provided on each side wall of the base 211; the fixed base 212 is an inverted regular polygonal pyramid structure, and is mounted outside the base 211, and is used to fix multiple lamp boards 221 on multiple side walls of the base 211, and each side wall of the fixed base 212 is provided with a light outlet hole 2121 for revealing the multiple floodlight beads 222.

[0089] The regular polygonal pyramid-shaped base 211 has multiple side walls, each of which faces different directions, so that multiple floodlight heads 22 can be installed, and the irradiation directions of the multiple floodlight heads 22 are different. In this embodiment, the base 211 is a regular pentagonal pyramid, and thus has five side walls, which are arranged circumferentially, that is, the angle between two adjacent side walls is 72°, and a lamp board 221 is installed on each side wall. At the same time, a plurality of floodlight beads 222 are arranged on the lamp board 221. In this way, the plurality of floodlight beads 222 on the five lamp boards 221 can also be arranged circumferentially and generally form a ring-shaped light belt, and respectively shine in five different directions, so that its irradiation range can generally cover the entire space, that is, 360° irradiation, thereby reducing the blind spots in the space, so as to facilitate the use of workers. The fixing base 212 is also a regular pentagonal pyramid and is connected to the bottom plate. It has five side walls and is slightly larger in overall size. Therefore, the fixing base 212 can be wrapped around the outer wall of the base 211, thereby simultaneously pressing and fixing the five lamp panels 221 on the base 211. The light-transmitting holes on the five side walls of the fixing base 212 can be used to avoid multiple floodlight beads 222 to avoid affecting the light output of the floodlight beads 222.

[0090] Advantageously, in some other embodiments of the present invention, the base 211 is a hollow structure and is integrally formed with the bottom plate 111 .

[0091] The hollow structure of the base 211 can save materials, thereby reducing the cost of the lamp, and the base 211 and the bottom plate 111 are formed in one piece, which is convenient for mold opening and is beneficial to production.

[0094] Preferably, the protection frame 30 is made of stainless steel.

[0095] The protective frame 30 is connected by an annular mounting plate 31, a middle mounting ring 32, a bottom mounting ring 33 and a plurality of arc-shaped connecting rods 34 to form a structure with a generally hemispherical outline. There is a gap between two adjacent arc-shaped connecting rods 34 to facilitate the passage of light. The protective frame 30 is made of stainless steel as a whole. On the one hand, the protective frame 30 has good corrosion resistance, so that in harsh environments such as mining areas, the protective frame 30 is not easily corroded, thereby ensuring its service life; on the other hand, the protective frame 30 also has good collision resistance and is not easy to be damaged, so it is beneficial to protect the lampshade 23.
