DRIVING APPARATUS OF LIGHT EMITTING DIODES

摘要

PURPOSE: A driving apparatus of light emitting diodes is provided to reduce a circuit size and manufacturing costs. CONSTITUTION: A power supply unit(110) supplies drive power to a light emitting diode. The power supply unit includes a photocoupler(111), a power control part(112), and a power source converting part(113). A first control unit(120) controls the power supply unit. A second control unit(130) controls a light emitting part.
