The invention discloses an LED embedded barrel lamp which comprises a front cover and a radiator, wherein the front cover and the radiator are matched and connected together, the radiator comprises a radiator body and a protecting cavity which is positioned outside the radiator body and shares the same bottom surface with the radiator body, and the inside of the protecting cavity body is providedwith two chambers which are respectively a driving chamber for installing a driver and a terminal chamber for installing a wiring terminal. Through the invention, the structure of the LED embedded barrel lamp becomes concise, the LED embedded barrel lamp is beautified, and moreover, the structural layouts of the driving chamber and the terminal chamber are compact, and the manufacturing cost of the radiator can not be markedly increased. In addition, the driver and an LED light-source module of the invention are respectively arranged in different chambers, and the driver and the LED light-source module do not directly contact, thus, the heat transferred from the LED light-source module to the driver can be reduced, and the service life of the driver is prolonged.
