The present invention relates to an LED lamp which is used to radiate light by being mounted on a socket such as an indoor or outdoor street light, a park light, a security light, a safety light etc. and, more specifically, to an LED lamp which has high light efficiency by radiating light from all angles and has a long lifespan by having excellent heat radiation of a light emitting diode (LED) and gives the substantial esthetic sense to a user by having a beautiful appearance. For this, the present invention is formed of; a socket combination unit which is combined to a socket with a screw method and includes a control unit to control the LED in the inner side; a heat radiation unit which is detachably fixated to the top of the socket combination unit and is formed into a cylindrical shape and includes one or more heat radiation paths; a heat radiation rod which is inserted and fixated to the top inner side of the heat radiation unit and is extended to the upper side with many sides over three sides and is mutually connected with the heat radiation path of the heat radiation unit by including a central path; an LED substrate which is bonded to the outer circumference surface of the heat radiation rod and arranges one or more LEDs which forms a bar shape; a fixing substrate which is placed on the heat radiation rod and the top of the LED substrate and forms multiple angles to be faced with the heat radiation rod and forms a hole on the center; and a cover which is combined to the top of the heat radiation unit and is formed into a cylindrical shape which is extended to the upper side to protect the LED substrate. The cover forms a recessed circulation hole on the upper side and is mutually connected to the central path of the heat radiation rod. |
