Abstract

A conductive rod includes an outer tube unit, at least one insulating member, and a conductive unit. The outer tube unit is made of conductive material, and has a first end and a second end, the first end and the second end are communicated with a tube space. The insulating member is disposed on the first end of the outer tube unit. One end of the conductive unit is positioned on the insulating member, and the other end of the conductive unit extends toward the second end along the tube space of the outer tube unit. The conductive unit is not in contact with the outer tube unit. The present invention also provides a lamp, comprising at least one conductive rod as described above, a lamp holder combined with a top end of the conductive rod, and a base combined with a bottom end of the conductive rod.
