REMOTE DIMMING CONTROL AND MONITORING SYSTEM OF LED STREET LIGHT

摘要

PURPOSE: A remote dimming control system for an LED street light is provided to reduce power consumption by precisely and uniformly controlling the dimming. CONSTITUTION: A protection circuit(301) protects a dimming controller(11a) from an excess current and a surge. An SMPS power circuit(304) generates driving power from the input of a power line. A noise and impedance filter(306) reduces noise generated from the SMPS power circuit and a power factor correction circuit(305). An LED driving SMPS circuit(307) generates driving power for driving an LED lamp(11b).
