APPARATUS FOR DELIVERING INPUT VOLTAGE OF LIGHT EMITTING DIODE LIGHTING SYSTEM

摘要

PURPOSE: An input voltage transfer device for a light emitting diode lighting system is provided to effectively maintain dimming by turning on a switching element for a predetermined time with zero voltage input. CONSTITUTION: A power supply voltage storage unit(220) stores a power supply voltage. The power supply voltage storage unit discharges the power supply voltage if a non-zero voltage switching unit(240) is turned on. The power supply voltage storage unit comprises a first resistance and a first capacitor. A zero voltage switching unit(210) is turned on by the power supply voltage saved in the power supply voltage storage unit. The non-zero voltage switching unit is turned on by a current transferred through the zero voltage switching units.
