摘要： An LED lamp includes a plurality of LED modules, a cone-shaped heat absorbing member, a heat sink and an envelope. The heat absorbing member comprises a plurality of heat absorbing portions. Each of the heat absorbing portions has a configuration like a triangular pyramid and comprises a sector base and an inclined surface extending from an edge of the sector base to a single apex. Each of the LED modules is attached on a corresponding inclined surface. The heat sink thermally connects with the heat absorbing member. The envelope is mounted below the heat sink and engages with the heat sink to enclose the heat absorbing member and the LED modules therein. Heat generated by the LED modules is first absorbed by the heat absorbing member and then dissipated to ambient air through the heat sink.

摘要： An LED lamp includes a hollow, prism-shaped heat sink (30), a plurality of LED modules (20) attached on sidewalls (320) of the heat sink, a cover (40) mounted on a top of the heat sink, a lampshade (10) secured to a bottom of the heat sink, and a fan (50) fixed on the top of the heat sink and through the cover. A plurality of fins (340) extends inwardly from inner faces of the heat sink to cooperatively define two crossed slots in the heat sink. When the fan is in operation, an airflow produced by the fan flows through the fins from the top through the bottom of the heat sink, thereby dissipating heat absorbed by the heat sink from the LED modules rapidly and efficiently.
