PURPOSE: A lighting device is provided to prevent installation costs by fixing a lighting lamp through a magnetic force. CONSTITUTION: A transmission coil unit(200) is arranged the outside of a magnetic force generator. The transmission coil unit generates resonance with magnetic induction. The transmission coil unit transmits voltages by generating a non-radiative radio wave. A lighting lamp(400) is fixed with a magnetic force of the magnetic force generator. A receiving coil unit(500) supplies power to the lighting lamp. |
