Abstract: The connector comprises two coupling elements (1) in each of which end parts of light conducting fibres (9) are secured mutually in parallel beside each other in such a manner that the centers of their end faces (15) are situated on one line (17) in an end face (19) of the coupling element (1). The connector further comprises a connector housing (25) for receiving the two coupling elements (1). Each coupling element (1) has a cylindrical outer surface (20) the axis of which coincides with the axis of the light conducting core of one of the fibre end parts (9) secured therein (preferably the central one) and which is capable of cooperating with a centring member (27) of the connector housing (25). Each coupling element furthermore has an orientation element (23) which is capable of cooperating with an orientation member (29) of the connector housing (25).

Abstract: Low-pressure discharge lamp having an elongate discharge vessel which contains a thinly distributed filamentary body permeable to the gas discharge, said body comprising a helical support filament which is supported by the inner surface of the discharge vessel and is at least one further filament, supported by the support filament and extending therefrom towards the axis fo the discharge vessel.
