Abstract

The utility model discloses a light-emitting diode (LED) light source and a ceiling lamp. The LED light source comprises an aluminum substrate, a plurality of LED beads arranged on the aluminum substrate, and a drive circuit connected with the LED beads. The total power of the plurality of LED beads is set from 10 watts to 20 watts, and the power of each LED bead is set from 0.05 watt to 0.2 watt. The size of the aluminum substrate is determined by the number of the LED beads. Interval distance between neighboring LED beads is equal to and not less than 1.5 centimeters, and the size of the aluminum substrate is not more than 1 square meter. Thus, the LED beads of small power are adopted as a light source and arranged on the surface of the aluminum substrate uniformly, compared with LED beads of large power, the LED light source is more uniform in light emitting effect and good in light effect and, and good head radiation effect can be achieved without additional radiators. Meanwhile, the LED light source and the ceiling lamp are simple in structure, small in size and simple in production process, and greatly reduce production cost.
