PURPOSE:To previously set the length of wiring on the back of a ceiling for supply of electric power to a lighting equipment. CONSTITUTION:This lighting equipment with a ceiling plate is provided with a lighting equipment 3 fitted and fixed on the nearly center on the back of a non-combustible fire-resisting ceiling plate 1 and a feeder port 4 connected to the lighting equipment 3. The end part 5 of the feeder port 4 introduced from the lighting equipment 3 to the outside is at least elongated up to the peripheral edge of the ceiling plate 1. Consequently, because the feeder port of the lighting equipment fitted to the ceiling plate is elongated up to the peripheral edge of the ceiling plate, wiring on the backside of the ceiling can be previously set as the length up to the adjoining ceiling plate, wiring work can be further simplified, regardless of the size of the ceiling plate. |
