Lighting appliance

摘要

A lighting appliance (1) provided with, a power supply unit (2) provided with; a first housing (21), a rectifier (26) accommodated in the first housing for converting an AC current to a DC current, a first electricity-supplying connector (23) provided on a side of the first housing, and a lighting unit (3) provide with; a second housing (30), a power supply line provided with, an electricity-receiving connector (32) which is provided on a side of the second housing, and constituted to be electrically and mechanically connectable with the first electricity-supplying connector of the power supply unit, a second electricity-supplying connector (34) which is provided on a side other than the second housing, for feeding out the DC current received by the electricity-receiving connector, a second electricity-supplying connector having the same feature with the electricity-supplying connector of the power supply unit, a bus-line connected between the electricity-receiving connector and the second electricity-supplying connector, a current regulator (39) accommodated in the second housing, which is connected to the power supply line, and a light emitting semiconductor (38) accommodated in the second housing, which is driven by the output power of the current regulator.
