摘要

The holder comprises an inner tube (50) and an outer tube (70) which can be rotated relative to each other about the holder length axis in order to provide electrical contact with the wire contacts. The holder has an elongated shape and the inner and outer tubes are both cylinder-shaped with an opening in their peripheral surface which extends in the tube length direction for receiving one free end of the lamp. An electrical contact body (60) contains an opening (64) for locating the wire contacts. The tubes and contact body are aligned in the holder length direction. An independent claim is also included for a light fitting for a fluorescent lamp, comprising at least two of the above outer tubes which are spaced apart and designed to receive at least one fluorescent lamp having one of the above inner tubes provided at both ends.
