Abstract

Disclosed herein is a downlight, which includes an optoelectronic module and a rim module. The optoelectronic module includes a light source driving board, a back housing, and a front housing. The light source driving board is disposed between the back housing and the front housing. The light source driving board includes a light-emitting diode unit and a driving circuit. The rim module has a central opening for accommodating the optoelectronic module. The rim module includes a tubular wall and a fastener, in which the fastener is fixed on the tubular wall. The fastener has a first bent portion and a second bent portion, in which the first bent portion is configured to be fixed in the accommodation hole, and the second bent portion is fixed on the tubular wall of the downlight.
