Abstract
The utility model relates to the field of illuminating lamps, in particular to a light-emitting diode (LED) ceiling lamp. An LED module is connected with a radiator, one face of the radiator, far from the LED module, is provided with a groove, and a fan is arranged in the groove. The LED ceiling lamp further comprises a separating board, the separating board covers the radiator, an air inlet is formed in the separating board, and the separating board is in abutted connection with the inner wall of a lamp tube. Heat produced by the LED module is transmitted to the radiator quickly, the separating board is in abutted connection with the inner wall of a lamp tube so as to divide the lamp tube into an upper portion and a lower portion, and the radiator is arranged on the lower portion of the separating board. Driven by the fan, external air contacts the radiator, and therefore temperature of the radiator is reduced. The separating board ensures that the external air keeps original temperature, while the temperature of the lower portion of the separating board is higher than that of the upper portion of the separating board due to increase of accumulated heat of the radiator, the fan can drive the air inducted from the outside to contact the whole radiator, and therefore heat of the radiator can be reduced, and good radiation effect can be achieved.
