LIGHT EMITTING DIODE DRIVING APPARATUS AND LIGHT EMITTING DIODE LIGHTING APPARATUS |
| 摘要 |
There are provided a light emitting diode driving apparatus and a light emitting diode lighting apparatus capable of absorbing a noise current generated according to power of a phase control of a dimmer. The light emitting diode lighting apparatus includes: a dimmer controlling a phase of an alternating current (AC) power; a power supplying unit receiving the phase-controlled power from the dimmer and supplying a preset driving power; a driving unit receiving the driving power from the power supplying unit to drive a light emitting diode unit receiving the phase-controlled power; and a noise current absorbing unit suppressing an increase in a voltage level of the driving power supplied to the driving unit by the phase-controlled power. |
