Abstract
The utility model relates to an LED ceiling lamp. The LED ceiling lamp comprises an outer ring. A radiator stretching into the outer ring is arranged on the outer ring. An exposed heat dissipation cavity is formed in the lower end of the radiator, an LED lamp body is arranged on the top wall of the heat dissipation cavity, and a light-transmitting piece is arranged at the front end of the LED lamp body. According to the technical scheme, the radiator is provided with a plurality of communicated heat dissipation channels stretching from the upper end face of the radiator to be communicated the heat dissipation cavity. The LED ceiling lamp is simple in structure; because heat in the heat dissipation cavity is conducted outwards through the heat dissipation channels, the heat dissipation performance is good.
