Light emitting diode driving apparatus

摘要

There is provided a light emitting diode driving apparatus satisfying regulations for current transferred to a light emitting diode. The light emitting diode driving apparatus includes: a power supplying unit receiving input power to convert the input power into a preset driving power and supplying the driving power to a light emitting diode unit including at least one light emitting diode; a detecting unit receiving the driving power supplied to the light emitting diode unit to detect voltage flowing in the light emitting diode unit; a controlling unit comparing detection voltage detected by the detecting unit with a preset reference voltage to control a power conversion operation of the power supplying unit; and a driving unit driving the power conversion operation according to controlling by the controlling unit.
