Abstract
An energy saving LED lamp includes an illuminating device, a mode switching device, a motion detecting device and a controlling unit. The illuminating device is for emitting light. The mode switching device is for switching the illuminating device to work between an illuminating mode and a power saving mode. The motion detecting device is for detecting surrounding human motions and generating a first signal in condition that there is no human motion detected around the LED lamp within a predetermined period of time. The controlling unit is for receiving the first signal generated by the motion detecting device and automatically adjusting brightness of light generated by the illuminating device when having received the first signal, when the mode switching device is at the energy saving mode.
