EMERGENCY SYSTEM FOR LED TUNNEL LIGHTING FIXTURE OF SMART MICRO PROCESSER

摘要

PURPOSE: An LED tunnel lamp including an emergency system by an intelligent microprocessor is provided to promote the safety of a driver by including an emergency lamp using a charged battery when power is not supplied. CONSTITUTION: An LED module holder(20) changes a light emission direction. A constant current driver system(30) controls currents supplied to a plurality of LED modules. A backup battery supplies power to an emergency lamp in a power outage. A charging and discharging controller is connected to the battery and controls the charging and discharging of the battery. A microprocessor connects a second lamp and a third lamp when the emergency lamp is trouble. A lamp sensor(70) senses the abnormal state of the emergency lamp. A current sensor controls the charging current and the discharging current of the battery. An input voltage sensor(80) senses the abnormal state of AC.
