Abstract:
Disclosed is an LED lamp having broad and uniform light distribution. The LED lamp comprises: a PCB on which a plurality of LEDs for emitting lights are mounted; a floodlight unit, opposed to the surface on which the LEDs of the PCB are mounted, having a predetermined angle to diffuse the lights emitted from the LEDs in different main light distribution directions corresponding to the predetermined angle; a supporting unit which supports the PCB; and a power supply unit which supplies power to the LEDs.
