APPARATUS FOR DRIVING ILLUMINATION OF LIGHT EMITTING DIODE

摘要

PURPOSE: A light emitting diode illumination driving unit is provided to effectively control peak current by controlling a plurality of LED array group by using constant current source and standard voltage generating unit. CONSTITUTION: A power supply unit(10) supplies a current power. A LED array group(20) is connected in parallel at a power supply unit. An LED array group has a plurality of LED group comprised of at least one LED. A standard voltage generating unit(30) is connected to the power supply unit in parallel. A switching unit(40) lights the peak current in orders per each LED group based on standard voltage.
