A graphene heat-dissipation LED lamp, comprising an LED light source module, a power supply module, a lamp housing () and a waterproof power strip (). The LED light source module is connected to the power supply module by means of the power strip () to form an LED module assembly. A graphene heat-conducting material is added to the LED module, so that the heat conduction efficiency is improved and the service life is prolonged. In addition, the lighting performance of the LED lamp is further improved. By configuring independent modules and using a quick connector, the LED lamp can be quickly mounted without a disassembling tool.
