Date Oct. 9, 1986.A wholly enclosed armature for fluorescent tubes, which is designed for outdoor use, has a transparent, cylindrically tubular cover member (18) which supports at the one end a permanent coupling housing (23) and at the opposite end supports an easily detechable end cover (22). A fluorescent tube-carrying support arrangement (24) is axially displaceably received in the cover member (18) between the coupling housing (23) and the end cover (22). The inner end of the support arrangement (24) is provided with guide members (42,43) of a first type which cooperate with guide members (47-49) of an equivalent second type on the coupling member. The support arrangement and the coupling member are provided with their respective contact members which form a current connection between the support arrangement and the coupling member and which are relatively moveable inwardly into and outwardly from engagement with each other guided by the said guide members (42,43; 47-49). |
