DRIVING APPARATUS FOR LIGHT EMITTING DIODE |
摘要 |
There is provided a driving apparatus for a light emitting diode (LED) comparing a rectified power voltage level with an LED current to limit current applied to an LED, thereby reducing the amount of heat generated therein. The driving apparatus for an LED includes a detecting unit detecting a voltage level of rectified power; and a driving unit comparing a level of current flowing in an LED unit having at least one LED with detection results from the detecting unit, and limiting current applied to the LED unit to drive the LED unit according to comparison results.
