Further, the face ring 3 on the illumination device 100 and the face ring 3' on the illumination device 100' can be used in common, that is, the face ring 3 and the face ring 3' have the same specifications and sizes, and the spotlight needs to be applied. In this case, the lamp body 1 of the illuminating device 100 and the face ring 3 are integrally assembled, that is, they can be used as a spotlight; when the downlight is applied, the lamp body 1' of the illuminating device 100' and the face ring 3 are assembled into One unit can be used as a downlight.

The illumination device 100, 100' provided by the first embodiment and the second embodiment of the present invention passes the second screw 8, 8' between the

face ring

3, 3' in the illumination device 100, 100' and the lamp body 1, 1'. The detachable connection is realized, so that the

face ring

3, 3' can be applied to other lighting devices, so that the

face ring

3, 3' is reused, thus reducing the development input cost and avoiding waste.
