POWER SUPPLY FOR LIGHTING DEVICE

摘要

PURPOSE: A power supply apparatus for a lighting apparatus is provided to employ a linear type LED operation part, thereby supplying power to an LED lighting apparatus with a low cost. CONSTITUTION: A power supply apparatus(100) is comprised of an SMPS(Switching Mode Power Supply) part(10) and an LED operation part(20). The SMPS part is comprised of an AC-DC converter(11) and a DC-DC converter(12). The DC-DC converter converts DC voltage to be suitable for the operation of a connected LED panel(200). The LED operation part controls the DC voltage converted in the DC-DC converter. The LED panel is a light source which includes one or more LEDs.
