LED LAMP MANAGEMENT SYSTEM USING AC PHASE CONTROL

摘要

PURPOSE: An LED device and an LED device management system using an AC phase control method are provided to reduce operation costs in comparison to a constant current driving method. CONSTITUTION: A light device control server(200) generates a basic illumination control value and illumination change data. An LED lamp unit(600) has a plurality of LED units. The plurality of LED units is connected between the first and second electrodes. A lamp driving controller(500) is connected to an AC power source and a dimming line. The lamp driving controller applies a constant voltage to the first and second electrodes. A local illumination controller(450) is connected between the lamp driving controller and the light device control server and controls the illumination. The local illumination controller controls the illumination of the LED lamp unit according to the operation mode.
