The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

As shown in fig. 1-2, a heat dissipation casing of an underground illuminating lamp comprises a cylinder body 1, a plurality of heat dissipation rings 2 sequentially sleeved outside the cylinder body 1, and a pressing ring 3 detachably fixed on the cylinder body 1 and located behind the heat dissipation rings 2, wherein a plurality of first heat dissipation ribs 21 uniformly arranged at equal angles along the circumferential direction are outwards formed on the inner wall of each heat dissipation ring 2, correspondingly, the same number of grooves 12 uniformly arranged at equal angles along the circumferential direction are formed on the outer circumferential surface of the cylinder body 1, and the end parts of the first heat dissipation ribs 21 on each heat dissipation ring 2 are respectively inserted into the grooves 12; an annular flange 11 is formed outwards at the edge of an opening at the front end of the cylinder body 1, the front sides of the end parts of the first heat dissipation ribs 21 on the heat dissipation ring 2 at the forefront are all attached to the outer wall of the rear side of the annular flange 11, and the rear sides of the end parts of the first heat dissipation ribs 21 on the heat dissipation ring 2 at the rearmost are all attached to the outer wall of the front side of the pressing ring 3; an external thread portion 13 is formed on the outer peripheral surface of the cylindrical body 1, and correspondingly, an internal thread portion 31 is formed on the inner wall of the pressing ring 3, and the internal thread portion 31 is engaged with the external thread portion 13.

A plurality of second heat dissipation ribs 22 uniformly arranged at equal angles along the circumferential direction are formed outwards on the outer wall of the heat dissipation ring 2.

A partition plate 14 is formed inside the cylinder 1.
