The present invention relates to a heat radiator mounted on an LED lamp. The heat radiator comprises: a support frame which has a longitudinal shape; a pair of heat sinks which include at least two heat radiation frames connected to the side of the support frame, wherein the heat radiation frame has a longitudinal plate shape; a placement plate which has a longitudinal plate shape, and connects the ends of the heat sinks; a plurality of heat radiation protrusions which are formed on the outer side of the heat sink in a lengthwise direction; and coupling grooves which are formed at both ends of the pair of heat sinks in the lengthwise direction to couple the side of an LED board, wherein the support frame and the heat radiation frame are made of aluminum, and are manufactured by drawing. According to such a configuration, heat is easily emitted into the air, it is possible to compactly manufacture the LED lamp, air freely moves to the heat radiation protrusions by the connection frame, heat is easily radiated, and it is possible to form a plurality of heat radiation frames so it is possible to variously design the LED lamp. |
