Zusammenfassung:	The utility model provides a ceiling fan lamp with an air duct, which belongs to the technical field of lamps and comprises a casing, a fan and a grating, an air inlet is arranged at the upper end ofthe casing, an air outlet is arranged at the lower end of the casing, the casing is internally provided with the closed annular air duct, and the annular air duct is gradually enlarged from top to bottom. The fan is arranged in the shell; the grating is arranged at the air outlet of the shell; air is sucked into the shell through the air inlet, is pressurized through the annular air duct, is unfolded and is discharged through the grating. According to the ceiling fan lamp with the air duct, due to the fact that the annular air duct which is gradually increased from top to bottom is arranged inthe shell, the fan rotates in the shell to form negative pressure, sucked air enters the shell through the air inlet, gathers and is pressurized through the annular air duct, then is gradually depressurized and then is discha
