<p>An LED lighting device driven with an earthquake includes: an external power input unit which receives AC power from the outside; a rectifier unit which converts the AC power into DC power; a converter unit which converts the DC power into an LED driving voltage; an LED unit which emits light by the driving voltage; a battery unit which is charged with the LED driving voltage of the converter unit; an earthquake sensing unit which outputs an earthquake signal by sensing the vibration of the earthquake; and a control unit which supplies the LED driving voltage which is charged in the battery unit into the LED unit when the earthquake signal is received from the earthquake sensing unit and an external power blocking signal is received from an external power sensing unit. [Reference numerals] (110) External power input unit;(120) External power sensing unit;(130) Rectification unit;(140) Converter unit;(150) LED unit;(160) Battery unit;(170) Earthquake sensing unit;(180) Control unit</p> |
