Zusammenfassung:	A solid-state light emitting diode (LED) lighting device is disclosed for use in general lighting. In the preferred embodiment, the LED lighting device comprises a heat sink having at least one opening, an output globe having at least one opening, and at least one ventilation channel. This channel helps to remove heat from the LED lighting device. An active cooling device is further installed inside the channel for very efficient heat removal. As a result, even at high luminous output, the LED lighting device is kept in a relatively small form factor. In some preferred embodiments, remote wavelength conversion luminescent phosphor particles or color mixing are utilized to achieve warm white lighting with high efficacy and high color rendering index (CRI). The LED lighting device has high luminous output, glare-free illumination, omni-directional distribution, and good color reproduction.
