Patent ID: 8076855

Claim:
A light device comprising: a nightlight unit adapted to operate in an automatic mode, an on mode, or an off mode; an illumination unit comprising a sensor, the illumination unit being removably secured to the nightlight unit; and a charging unit for charging the illumination unit, wherein the illumination unit is adapted to come on automatically by operating in the automatic mode, continuously emit light by operating in the on mode, or stop emitting light by operating in the off mode; wherein the illumination unit is adapted to come on automatically to emit light either when the sensor senses an activating condition in the form of an absence of AC (alternating current) or after removing from the nightlight unit; wherein the sensor is adapted to disable the illumination unit either when sensing a termination of the activating condition or after placing the illumination unit in the nightlight unit and electrically connecting thereto; and wherein the charging unit comprises a first winding, a second winding in the illumination unit, an input, a first voltage decreasing circuit, a first full-wave rectifier, a vibration circuit, and an output such that the AC energy from an electrical outlet is fed to the input, the voltage value of the AC energy is decreased by the first voltage decreasing circuit, voltage with decreased value is rectified and filtered by the first full-wave rectifier, the vibration circuit generates a vibration signal and sends same to the output, and the vibration signal is sent from the output to the first winding.
