Abstract

The lamp/reflector unit comprises a reflector (1) having a neck-shaped portion (3) in which a metal centering member (9) is present. The centering member (9) has a transverse wall (10) with an opening (11) in which the seal (6) of an electric lamp (4) is accommodated, secured with cement (12). Recesses (13) extend from the opening (11) into the transverse wall (10). Fracture of the seal (6) is thus prevented.
