FIELD: electricity. ^ SUBSTANCE: lamp comprises contact pins installed on its end cap and protruding outside along longitudinal axis of end cap. Contact pins are displaced some in respect to the others along longitudinal axis. End cap has semicircular parallel surfaces at one end, so that contact pins protrude outside from according parallel semicircular surfaces. Between semicircular surfaces there is a barrier wall arranged perpendicularly. In the first version of invention realisation, a ledge is outgoing from specified barrier wall along at least part of lower semicircular surface. Ledge reaches upper semicircular surface. In alternative version in border wall there is a lot, which also passes between upper and lower semicircular surfaces. ^ EFFECT: by giving stepped shape to end cap with ledge or slot, which passes in the middle of end cap along barrier wall, connection between lamp and cartridge is improved, and proper position of contact pins in cartridge seats is maintained. ^ 22 cl, 29 dwg |
