Abstract
A light emitting diode lamp includes a lamp base defining a plurality of openings, at least one power module, and a number of illumination modules. Each illumination module includes a number of illumination units. Two opposite terminals of each illumination unit are secured to the lamp base near two opposite edges of a corresponding opening. The illumination units are in the openings and apart from each other. Each illumination unit includes a heat dissipating assembly, at least one lighting assembly, and two connection units connected to two opposite terminals of the heat dissipating assembly. The power module supplies electrical power to at least one illumination module, and controls a power supply through at least one of the two connection units to electrically connect the at least one lighting assembly.
