▎ 摘　　要

NOVELTY - The lamp has a printed circuit board (PCB) (2) tightly attached to a heat dissipation device (1) with a thermally conductive grease layer (3) being provided between the heat dissipation device and the PCB. The thermally conductive grease layer comprises a thermally conductive graphene adhesive. The thermally conductive grease layer is located between a radiating bottom plate (10) and the PCB. A side of the radiating bottom plate opposite to the PCB board is provided with two mutually parallel radiating ribs (11). USE - LED lamp. ADVANTAGE - The thermally conductive grease layer effectively transfers the heat generated by the PCB to the heat dissipation device so as to dissipate the heat. The lamp enables graphene used as a thermally conductive carrier, thus improving reliability of the lamp, reducing amount of heat dissipation material and prolonging service life of the LED lamp. The lamp is simple in structure. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of an LED lamp.
