Abstract
The invention discloses a ceiling lamp which comprises an LED component, a drive power supply and a reflector. The LED component comprises an aluminum substrate integrating a plurality of LED lamps and a radiating cylinder. The surface, with the LED lamps, of the aluminum substrate is a protruding arc-shaped face protruding towards a light emitting end. The aluminum substrate is disposed at the first end of the radiating cylinder and located in the reflector. The aluminum substrate and the radiating cylinder are integrally formed. The drive power supply is accommodated in the radiating cylinder. The light inlet end of the reflector is fixedly connected with the first end of the radiating cylinder. The ceiling lamp has the advantages that the LED lamps are fixed on the aluminum substrate in an integrated manner, so that heat emitted by the LED lamps can be conveniently absorbed by the aluminum substrate; the aluminum substrate and the radiating outer cylinder are integrally formed, so that the heat of the LED lamps can be effectively radiated outwardly through the radiating outer cylinder, and the radiating efficiency of the whole lamp is high; the surface, with the LED lamps, of the aluminum substrate is the protruding arc-shaped face protruding towards the light emitting end, so that light is distributed in the front and on the periphery of the LED component; the whole LED component is matched with the reflector, so that long-distance irradiating is facilitated, and high illuminance is achieved.
