The light source substrate 211 is mounted on the bottom plate 12 of the housing 10 without being mounted on the bottom plate 12 of the housing 10, and is aligned with the bottom plate 12. . A through hole 121 is formed in the center of the bottom plate 12, and the arrangement of the through hole 121 contributes to heat dissipation of the photoelectric integrated module 20. A first wire hole 122 is also formed in the bottom plate 12 for penetrating the conductive wire 30 of the illumination device 100. On the outer surface of the bottom plate 12, at least two internally threaded posts 123 are formed. In the present embodiment, the number of internally threaded posts 123 is three.

The illuminating device 100 further includes a heat sink 40 mounted outside the casing 10, and the heat sink 40 includes a columnar portion 41 penetrating through the through hole 121 and abutting on the light source substrate 211, and a heat radiating fin radially arranged outside the column portion 41. Sheet 42. The heat sink 40 further includes a second wire hole 43 aligned with the first wire hole 122.
