A LIGHTING FIXTURE OF MULTIPLE POWER LINE FOR BOTH COMMON-USE AND EMERGENCY

摘要

PURPOSE: A lighting fixture of multiple power lines for both common-use and emergency is provided to maintain stable connection state of an emergency power line since a combo switch is formed to detect a branch line of the front end of a main switch. CONSTITUTION: A combo switch(40) switches common-use power lines(10a,10b) and emergency power lines(20a,20b). The combo switch comprises a coil part and a contact switch connected to a branch line(10c). An AC lighting control device(34) controls the lighting of a lamp(50) according to the opening and closing of the main switch. The DC lighting control device connects to the combo switch. The DC lighting control device lights on the lamp by the power of a storage battery(38).
