Abstract
An LED lamp includes a bracket, a heat sink mounted on a top side of the bracket, and a plurality of LED modules mounted on the heat sink. The heat sink includes a base and a plurality of mounting members extending downwardly from a bottom surface of the base. Each of the mounting members includes an extending plate formed on the bottom surface of the base and a mounting plate extending slantwise upwardly and outwardly at a bottom end of the extending plate. The LED modules are mounted on bottom surfaces of the mounting plates of the mounting members of the heat sink, respectively. The extending plates have gradually decreased lengths from two central ones thereof toward lateral ones thereof. The mounting plates and the bottom surface of the base form acute angles which are gradually decreased from a center of the base to lateral sides of the base.
