[0026] The heat dissipation assembly includes a heat dissipation body, a heat sink fixing cover 15 mounted on the upper end of the heat dissipation body, a heat dissipation fan 16 mounted inside the heat sink fixing cover 15, and a heat sink fixing cover 17 mounted on the lower end of the heat dissipation body and connected to the bottom of the explosion-proof cover 9. The heat dissipation body includes a plurality of heat dissipation unit components 20, which are arranged in a cylindrical shape in a circular array. Each heat dissipation unit component 20 is formed from an integrally molded aluminum profile or an extension of an aluminum profile material with a cross-sectional shape as shown in the figure.

[0027] The pattern includes a long arc-shaped arm 201 disposed on the inner side, a side semi-circular notch 202 disposed at one end of the long arc-shaped arm 201, and at least two font pattern pieces connected to the long arc-shaped arm 201; the font pattern pieces include a longitudinal rod 203 connected to the long arc-shaped arm 201, two first arc-shaped arms 204 and a second arc-shaped arm 205 disposed on the inner side of the longitudinal rod 203, a transverse rod 206 connected to the end of the longitudinal rod 203, and bent rods 207 disposed at both ends of the transverse rod 206, with a side groove 208 for accommodating the side lamp panel 10 disposed at one end of the outer side of the bent rod 207.
