ABSTRACT:
A halogen-metal vapor lamp (1) with its electrodes coming out of the discharge vessel at opposite ends is provided with a highly insulated socket at one end capable of withstanding 30 kV that may have to be applied for warm ignition of the lamp. Contact pins (9,10) of the socket (11) and connection bushings (22,23) of the support (21) into which the socket plugs in, are provided with collars (15,16;25,26) which lengthen the breakdown path length. The fused seal (7) of the lamp through which the high voltage is applied is cemented in a central opening of the socket body and additionally surrounded in part by a collar (17). The other end of the lamp is connected to the socket by an uninsulated rigid conductor in the form of a metal strip to facilitate the dissipation of heat by radiation. A projecting partition (24) at the bottom of the support (21) separates the voltage supply connection to the connection bushings.
