Abstract

An LED lamp includes a frame having a bottom surface, a plurality of heat sinks, and a plurality of LED modules. Each of the heat sinks has an engaging surface defined at an acute angle with respect to the bottom surface of the frame. Each of the LED modules is attached on the engaging surface of the heat sink. The heat sinks are rotatable relative to the frame to adjust the angle of the engaging surface of the heat sinks with respect to the bottom surface of the frame, providing variable area and intensity of illumination.
