Abstract
The utility discloses a light emitting diode (LED) bulb. The light emitting diode bulb comprises a bulb holder, a heat sink, three LED bulb panels and a bulb cover. The bottom of the bulb holder is provided with a power input end. The heat sink is installed on the bulb holder and the upper portion of the heat sink is provided with the three bulb panels which are spliced together. The three bulb panels surround the upper portion of the heat sink in 360 degrees. The bulb panels tilt gradually inward from the lower upward. The intersection angle between the bulb panels and horizontal plane is 120 degrees. The intersection angle between neighbouring bulb panels is 60 degrees. The three LED bulb panels are connected respectively with the corresponding bulb panels of the heat sink. The bulb cover is connected on the heat sink. A cavity is installed inside the heat sink. The device has the advantages of improving the light use ratio by adopting the ring installation of the three bulb panels on the heat sink and taking advantage of the emitting angle of the LED light source to enable the bulb to light in 360 degrees and light more evenly without the need of secondary light distribution operated by the LED light source.
