The invention relates to luminaires, especially luminaires to be operated in lamp holders for fluorescent lamps. In order to prevent individuals from experiencing electric shocks when inserting a luminaire, for example in the lamp holder of a fluorescent lamp, and in order to be able to operate the luminaire without complications once it is inserted in the lamp holder, the luminaire comprises a contact section to be inserted into a socket base, comprising two contact pins (B, B) and a centering device (BX) for centering the luminaire in the socket, which is mounted in the center between the contact pins (B, B). The centering device (BX) can be rotated about a main axis of the luminaire to actuate a switch or a protective device.

Light-emitting means, in particular for operation in lampholders for fluorescent lamps

A lamp with a light-emitting unit, at least two separate contact modules and an electrical connection between the light-emitting unit and the contact modules, wherein each contact module has at least one electrical contact for connecting to a corresponding lampholder, is presented and described. So that other lamps can be operated safely as gas-discharge lamps in lampholders provided for them, it is envisaged that at least one protective device for prevention of electric shock is provided on at least one of the electrical contacts in a partially assembled state of the lamp in a corresponding lampholder, and that the protective device is designed to assume a deactivated position in the assembled state of the lamp and an activated position in the dismantled state of the lamp.
