Lamp body unit for e.g. lighting tower, installed at e.g. airport, to enhance night vision, has lighting modules receiving operating current and emitting light, and operating circuit dividing current supplied through individual cable

摘要

The body unit (110) has an operating circuit dividing direct current (DC) current supplied through an individual cable (C) with an individual positive wire and an individual negative wire. The divided DC current is supplied to multiple power lines and converted into operating current for lighting operation. Multiple lighting modules receive operating current of the operating circuit and emit light. The operating circuit comprises a division unit that receives the DC current of a current transmission unit through the cable and divides the received DC current. An independent claim is also included for a lighting device comprising a lamp body holding unit.
