APPARATUS FOR DRIVING LIGHT EMITTING DIODE |
| 摘要 |
<p>PURPOSE: An apparatus for driving a light emitting diode is provided to constantly control output by adjusting voltage of a dimming control unit. CONSTITUTION: A rectifier (20) rectifies AC power. A light emitting unit (30) is connected to the rectifier. The light emitting unit comprises a plurality of light emitting diodes. The plurality of light emitting diodes is connected to each other in series. An electric condenser is connected to more than two groups (31-34) of the light emitting diodes.
