ABSTRACT:
A lighting apparatus comprises a power unit, a fan unit, a charging unit, a light source unit and a control unit. The power unit receives power from an external power source. The fan unit is rotated using the power supplied from the power unit. The charging unit stores power generated from rotation of the fan unit. The light source unit generates light. The light source unit employs an LED as a light source. The control unit connects the light source unit to the charging unit when power level of the charging unit is greater than a specified level, and the control unit connects the light source unit to the power unit when the power level of the charging unit is lower than the specified level. Therefore, power consumed by the lighting apparatus is reduced and vibration resistance of the lighting apparatus is improved.
