<p>PURPOSE: A device for supplying power of light emitting diode is provided to control the light emitting diode to simple circuit. CONSTITUTION: A power supply unit(200) supplies a voltage to a light emitting unit(500). A first switching unit(300) supplies or blocks the voltage supplied through the power supply unit to the light emitting unit. A second switching unit(400) acts contrary to the first switching unit. The second switching unit supplies or blocks the voltage supplied through the power supply unit. A control unit(100) control the first switching unit and the second switching unit through a high signal or low signal controller from the outside.</p> |
