The utility model relates to the field of LEDs, in particular to an LED lamp. The LED lamp is characterized by being mainly composed of a lamp body (7) and a power supply cover (12), a built-in power supply (11) is arranged at the top end of the lamp body (7) and forms a whole together with the lamp body (7), and the power supply cover (12) is connected with the lamp body (7). High-heat-conduction pure aluminum is embedded in cooling plastic, the weight is lower than that of metal, the installation and transportation difficulty is lowered, and potential personal safety hazards are reduced; the LED lamp is more environmentally friendly, safer and free of toxic pollutions and potential safety hazards produced by electric conduction of a shell; the LED lamp is convenient to machine, freer in design and more attractive in style; the LED lamp is low in cost, more stable in quality and capable of being recycled and repeatedly used; the built-in power supply (11) and the shell form a whole, and therefore the package size is reduced; by means of the buckle-in mode, the LED lamp is easy to install and simple in appearance and forms a plane together with a matching part.
