<p>PURPOSE: An apparatus for supplying power to a light emitting diode is provided to effectively adjust the color sense of the light emitting diodes by arranging a red light emitting diode, a blue light emitting diode, or a green light emitting diode on one of the light emitting diodes. CONSTITUTION: A light emitting diode group(300) connects an anode with an anode and a cathode with a cathode with respect to at least one light emitting diode. A switching group(200) comprises one or more switching devices which are parallelly connected to light emitting diodes of the light emitting diode group. The switching devices are turned on when a reverse alternating current voltage is applied to each light emitting diode. A switching controller(100) supplies a ground voltage or a high voltage, which is higher than the ground voltage, to the switching devices of the switching group.</p> |
