LED lamp

The utility model relates to the field of illumination design and particularly discloses an LED (light-emitting diode) lamp comprising an LED lamp directly plugged into a lamp socket made of metal heat-dissipation materials, wherein a power wire made with the inner layer thereof being made of conducting materials and the outer layer thereof being made of insulating materials is laid in the lamp socket; and part of the conducting materials in the inner layer of the power wire is exposed, and the pin of the LED lamp is electrically connected with the exposed conducting materials in the inner layer thereof. By directly mounting the LED lamp on a metal lamp socket rather than using the conventional structure of a circuit board and a cooling fin, the metal lamp socket can integrate the effects of fixed installation and cooling into a whole, i.e., the cooling fin can be in direct contact with the LED lamp, thus directly releasing the emitted heat to the air through heat conduction and preventing the heat from being
