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.
Claims5
An energy saving LED lamp comprising:
- an illuminating device for emitting light;
- a mode switching device for switching the illuminating device to work between an illuminating mode for which the illuminating device needs a manual operation to be changed from an illumination condition to another condition and a power saving mode for which the illuminating device is automatically changed from an illumination condition to another condition;
- a motion detecting device for detecting surrounding human motions, the motion detecting device generating a first signal in condition that there is no human motion detected around the LED lamp within a predetermined period of time;
- and
- a controlling unit for receiving the first signal generated by the motion detecting device and controlling the illuminating device to automatically change from the illumination condition to the another condition after having received the first signal when the mode switching device is at the power saving mode.
