Illumination appliance with support, containing two conductive tracks and current feeds from alternating current (AC) source, units with lamp, specified rectifier, second rectifier and contacts, with switch in one current feed

摘要

Support (12) has two conductive tracks (22) and two current feeds (28) from AC source (30). Lamp units (16,18), each contain lamp (32) and rectifier (34,36), each connected in different through direction and two contacts (26) for conductive tracks. In one current feed is located switch (14) with first current path (40) in parallel to second current path (42). Each current path contains switch (44,46) and one of differently connected rectifiers (34,36).
