A rotary heat-dissipation LED lamp comprises a lamp holder (1), a lamp core (3), and a lampshade (2) that encloses the lamp core. The lamp holder (1) and the lamp core (3) are connected by means a heat dissipation body (4). One side of the upper end of the heat dissipation body (4) is rotatably connected to the lamp holder (1) by means of a connecting bolt (5). The periphery of the heat dissipation body (4) is enclosed by pleated sheets (7). The heat dissipation body (4) is sealedly connected to the lamp holder (1) by means of the pleated sheets (7). The lower end of the heat dissipation body (4) is sealedly connected to the lamp core (3). The heat dissipation body (4) comprises heat sinks and heat insulation sheets. A plurality of lamp beads (6) is uniformly attached to the outer surface of the lamp core. The lamp core is of a cavity structure. A plurality of heat conducting rods is disposed in the cavity. The upper ends of the heat conducting rods penetrate through the heat insulation sheets so as to be connected to the heat sinks. The LED lamp has a good heat dissipation effect, and can be folded in use. |
