A lighting system comprising an electrical lamp () having an electrical lamp connector (), a holder () having a front electrical connector adapted to be back-connected to a power supply and a cap () to interface the electrical lamp and the holder, said cap extending along a mounting direction between a top side for receiving the lamp connector and an opposite bottom side for receiving the holder connector, and having axial holes extending between the bottom side and the top side for receiving within at least a part of an electrical cap connector able to electrically connect the lamp connector with the holder connector once the lighting assembly is assembled. The cap further comprises a cap guide and the holder further comprises a holder guide, said cap guide and holder guide being adapted to cooperate with one another by fitting in the mounting direction, such that any significant motion of the cap into directions perpendicular to the mounting direction is prevented by the holder guide, ensuring a positioning step of the cap with respect to the holder before an electrical contacting step of the cap connector with the holder connector.

Lighting system and cap for such lighting system

The invention relates to a supply connector () for a discharge lamp () of the type which includes an insulating housing () in which an opening () is provided for the axial introduction of a free end () of the glass body () of the discharge lamp () including a longitudinal electrode () formed by a front section () which extends to the exterior of the body () and a rear section () which extends inside a front section () of the free end of the body () and which is designed to be supplied with a direct current, and of the type in which a contact blade () is formed, which blade cooperates with the front section () of the electrode () for connecting the lamp () to an electrical supply member, characterized in that it includes an electrically conducting ring () which is connected to ground, which is axially traversed by the front section () of the free end of the glass body (), and which is designed to be at least partly in contact with a portion () of the outer wall of the glass body () of the discharge lamp () so as to facilitate the ignition of the latter.
