Luminaire for line illumination

摘要

The luminaire for line illumination has a trunk (10) to which a light carrier (1) is detachably fastened. The luminaire has a coupling member (20) inside the trunk (10) for aligning said trunk (10) with an adjoining trunk (10'). The coupling member (20) has a trunk-shaped coupling piece (21) with a top (22) at the outside of which a tensioning disc (30) with a relief (31) is present, which tensioning disc can be rotated by means of a rotation disc (40) present in the coupling piece (21) and coupled to the tensioning disc. When rotated, the relief (31) of the tensioning disc (30) is moved onto a relief (24) of the top (22) of the coupling piece (21). The coupling piece (21) is pressed thereby with its sides (23) into flanged portions (15) of the trunk (10) and is fixed therein in alignment with an adjoining trunk (10') which is passed over the coupling member (20).
