Abstract: A light emitting diode (LED) lamp for street lighting is provided. The LED lamp includes a curved lamp cover, a lamp case coupled to the lamp cover at one open end thereof, and a reflective plate fastened to the lamp case. The lamp case has an inner space in which a drive module for driving the lamp and a plurality of LED modules as light sources are mounted. The lamp case is divided into a first housing portion and a second housing portion. The first housing portion has a hollow space in which the drive module is fixedly installed. A channel-shaped mounting member configured to mount the LED modules thereon is installed in the second housing portion. The inner surface of the channel-shaped mounting member has two bends to form a central area and first and second side areas formed at both sides of the central area. The areas of the inner surface of the channel-shaped mounting member disperse light from the LED modules in different directions.
