LED lamp

The invention relates to an LED lamp with good heat dissipation effect and multiple paths to dissipate heat. The LED lamp comprises a lamp holder, a driving power source, an LED light source and a heat dissipation shell, wherein the lamp holder is installed on the heat dissipation shell and the LED light source and the driving power source are installed in the heat dissipation shell. The heat dissipation shell comprises an outer heat dissipation shell body, a heat dissipation connector and an inner heat dissipation shell body, wherein the outer heat dissipation shell body and the inner heat dissipation shell body are connected to the heat dissipation connector to form a cup body structure with a cavity interlayer. The LED light source is installed in the cavity formed by the outer heat dissipation shell body in an enclosure mode, the lower end of the inner heat dissipation shell body abuts against the LED light source, and the light-emitting component of the LED light source is located in the cavity formed by the inner heat dissipation shell body in an enclosure mode. The LED light source is connected with the outer heat dissipation shell body and the inner heat dissipation shell body and provided with the multiple heat dissipation paths, and therefore the heat of the LED light source can be dissipated faster, the heat dissipation efficiency can be improved, and the heat dissipation effect is good.
