Abstract
An LED lamp includes a base, a heat sink placed on a top surface of the base and a plurality of LED modules mounted on the heat sink. The base has a base plate, an engaging flange extending upwards from an edge of the base plate and a plurality of projecting vanes formed on a bottom of the base plate. The heat sink surrounded by the engaging flange comprises a core, a plurality of branches extending outwards from an outer circumference of the core and a plurality of fins formed on two opposite sides of each branch. Each branch defines an inclined surface on a top thereof and has a height gradually decreased along a direction outwards from the core. Each LED module has a printed circuit board mounted on the inclined surface of a corresponding branch of the heat sink.
