Abstract
A light emitting diode (LED) bulb includes a lamp seat for connecting the LED bulb to an external power source, a rotatable member rotatably connected to the lamp seat, two holders fixed to the rotatable member and a lamp head pivotally connecting with the holders. The rotatable member is rotatable around a first axis. The lamp head is rotatable around a second axis. The second axis is unparallel to the first axis. Thus, an illumination angle of the lamp head can be adjusted with respect to the lamp seat along two planes. An LED module is attached to the lamp head.
