Beschreibung
Zusammenfassung:	A downlight (100), including: a light source apparatus (20) and a heat dissipation set (10) configured for fixing the light source apparatus (20) and dissipating heat. The heat dissipation set (10) includes a heat dissipation annulus (11) and a heat radiation plate (12). The heat dissipation annulus (11) is provided with an accommodation cavity (113) configured for accommodating the heat radiation plate (12) and defining an opening. The light source panel (21) is connected to the heat radiation plate (12) through the heat conduction face (212), and configured to guide light outward through the opening of the accommodation cavity (113). The heat radiation plate (12) receives heat at the heat conduction face (212) and radiates the received heat to an inner wall of the accommodation cavity (113). Both the light source panel (21) and the heat radiation plate (12) are arranged in a non-contact way with the inner wall of the accommodation cavity (113).
