A discharge lamp is constructed by attaching a base to an outer tube, the base has a spiral feed member and a dotted feed member, and the shortest creeping clearance distance between the spiral feed member and the dotted feed member is defined to at least 6.0 mm. A socket for discharge lamp is constructed by providing a spiral receiving member and a contact piece in an insulating socket body, and the shortest clearance distance between the spiral receiving member and the contact piece is defined to at least 5.0 mm. A socket for discharge lamp is constructed by providing a spiral receiving member and a contact piece in an insulating socket body, and the shortest clearance distance between a socket reference line and the contact piece is defined to at least 19.6 mm.
A discharge lamp constructed by housing an arc tube having a pair of discharge electrodes in an interior of an outer tube having a sealed part at a one-end thereof and attaching a base to the one-end of the outer tube, and lighted by ignition voltage of 2.0 to 3.5 KVrms or pulse voltage of 3 to 5 KV in terms of maximum pulse height, and
A socket for discharge lamp, into which a base part provided on a discharge lamp lighted by ignition voltage of 2.0 to 3.5 KVrms or pulse voltage of 3 to 5 KV in terms of maximum pulse height is received, and
A socket for discharge lamp, into which a base part provided on a discharge lamp lighted by ignition voltage of 2.0 to 3.5 KVrms or pulse voltage of 3 to 5 KV in terms of maximum pulse height is received, and
