Patent ID: 8783905

Claim:
A lamp, including: a casing having a hollow chamber; a light-emitting assembly disposed totally within the hollow chamber; and a heat-dissipating module for dissipating heat generated by the light-emitting assembly, the heat-dissipating module comprising: a base plate made of sheet metal and connected to the top of the casing, which has a plurality of sides formed on edges of the base plate; and a plurality of fins formed by bending upwardly from the plurality of sides, respectively, each of the fins having a root integrally extend from a corresponding side and at least two bending sections, the at least two bending sections comprising a first bending section extending from the root to form a first bending angle with respect to the base plate and a second bending section extending from one lateral side of the first bending section to form a second bending angle with respect to the first bending section, a region among the bending sections and the base plate being hollowed to form a plurality of airflow channels, wherein a plurality of shrouds are formed in the hollow chamber, the light-emitting assembly includes a circuit board brought into directly thermal contact with a lower surface of the base plate and a plurality of LED arranged on the circuit board to be located within the plurality of shrouds, respectively.
