<p>The present invention provides a voltage supply device which includes a dimmer which converts AC input power into dimming power and outputs the dimming power, a rectifying unit which rectifies and outputs the dimming power, a transformation unit which transforms the rectified power at a preset ratio and outputs the transformed power to a light emitting diode, and an input unit which is connected between the dimmer and the rectifying unit, reduces the oscillation of the dimming power, and outputs the result to the rectifying unit. Therefore, triac operation conditions are satisfied by blocking an oscillation due to a capacitor and an inductor of a rectifier and the dimmer.</p> |
