Abstract

PURPOSE: To prevent the damage of the first contact of a main body side and the second contact of a lamp body side by breaking the connection to an up-and- down operation part of first power supply or breaking the connection of a lamp to second power supply interlocking with the operation of an operation part when the power supplies for lamp lighting and for up-and-down operation are different. CONSTITUTION: When the power supplies for lamp lighting and for up-and-down operation are different, a power supply breaker 12 breaking the connection of a lamp 9 to second power supply 11 interlocking with either the connection of first power supply 7 to an up-and-down operation part 6 or the operation of the operation part 6 is set. That is, since the second power supply 11 to the lamp 9 is broken in advance when a lamp body 8 having the second contact 10 of a moving side is separated from or is connected to a main body 1 having the first contact 2 of a fixed side, no sparks between the first and second contacts 2, 10 occur. Thereby, the damage of the contacts 2, 10 can be prevented.
