<p>PURPOSE: An LED module and a driving method thereof are provided to reduce manufacturing costs by using one magnet in one module through the maximization of magnet efficiency. CONSTITUTION: A light emitting device (44) emits light. A ferromagnetic material (43) supplies a current to the light emitting device. The ferromagnetic material is attached to the bottom of a magnet (42) or a support stand by receiving magnetic flux from the magnet. The magnet is arranged between the ferromagnetic materials and provides the magnetic flux to the ferromagnetic material. An insulator (45) prevents a short circuit between the magnet and the ferromagnetic material.</p> |
