Abstract
A light emitting diode (LED) lamp includes a lampshade, a light guide pole and a plurality of LEDs. The light guide pole is of light permeable material and received in the lampshade. A plurality of irregular elements is formed on an outer surface of the light guide pole. A distribution density of the irregular elements decreases gradually from two ends of the light guide pole towards a middle of the light guide pole. The LEDs are mounted at the two ends of the light guide pole. Light emitted by the light emitting diodes falls incident into the light guide pole and exits the light guide pole from the outer surface thereof.
