Abstract: The application provides a downlight emergency power supply device, including an emergency power box having an accommodation cavity; a connection structure configured to fix a luminaire to the emergency power box, and comprising two clamping assemblies arranged oppositely, wherein the clamping assemblies are elastically connected to an outer side of the emergency power box; and a power supply assembly, fixed in the accommodation cavity, and configured to supply power to the luminaire; wherein the two clamping assemblies clamp and fix the luminaire in an inward or outward rebound state. By setting two clamping assemblies to clamp and fix the luminaire on the emergency power supply, it is simpler and less time-consuming to assemble than the screw mounting method used in the related art, without the need for manual screwing. Besides, the two clamping assemblies of the connection structure can be automatically clamped, achieving semi-automatic assembly, which is convenient and efficient.
