The present invention relates to a light emitting body 23 and the socket 20 for the lamp 15. In the form of sockets it may also be implemented independently of the type of the luminous material (23). The socket has a supply terminal region on the socket housing multiple sides of that socket 20 selective electrical supply and the wiring connection at the same time from these or also multi-side from different sides. The number of supply terminal regions 94 and the arrangement and is, independently, with multiple electrical supply terminals having the same polarity (95) is provided to the socket 20. It said supply terminal having the same polarity (95) is a short circuit by the two identical short-circuit connector is arranged to short-circuit connector 116, in particular a socket housing (116). The socket 20 and the light-emitter 23 to achieve the larger the total light-emitting surface in the lamp 15 in a modular fashion and forms an unappealing appearance in a very simple manner.
