Zusammenfassung:	The utility model relates to a light-emitting-diode (LED) lamp. The LED lamp comprises a barrel-shaped lamp shell, a disc-shaped lamp holder fixing base, an LED lamp holder and a reflection cup. Heat dissipation fins are evenly arranged outside the lamp shell, the lamp holder fixing base is fixed in an inner hole of the lamp shell, the LED lamp holder is fixedly connected on the lower portion of the lamp holder fixing base, the top end of the reflection cup abuts against the lower portion of the LED lamp holder, the outer wall of the reflection cup abuts against the lower end of the inner hole of the lamp shell, and the LED lamp holder is in electric connection with an external drive power source. According to the LED lamp, heat generated by the LED lamp holder can be transmitted onto the heat dissipation fins on the barrel-shaped lamp shell through the lamp holder fixing base and also can be transmitted to the lower end of the inner hole of the lamp shell through the outer wall of the reflection cup, therefo
