Abstract
A light emitting diode bulb includes a lampshade, a lamp housing, a heat sink, a driving circuit, light emitting diode modules and a lamp cap. The lamp housing is connected to the lampshade and includes a cup-shaped casing and a heat conduction part. The heat conduction part is disposed in the cup-shaped casing. The heat sink is disposed in the lampshade and includes a heat-dissipating shell and a heat-dissipating frustum. The heat-dissipating shell covers the heat conduction part. The heat-dissipating frustum includes a top surface, a bottom surface and four side surfaces. The heat-dissipating frustum includes an axis vertical to the bottom surface. An included angle between the axis and each of the side surfaces is smaller than 90 degrees. The light emitting diode modules are adhered to the top surface and the side surfaces and connected to the driving circuit. The lamp cap is connected to the driving circuit.
