1. An illumination system comprising:
at least one mounting profile rail (60a, 60b, 60c), without a power rail, for the accommodation of at least one lighting unit (70), which can be introduced into the mounting profile rail, and
at least one supply connector (50a, 50b, 50c), which can be introduced into the mounting profile rail;
wherein the mounting profile rail (60a, 60b, 60c) is designed as an extruded plastic or aluminum profile,
wherein the at least one lighting unit (70) is designed as a long, rigid strip,
on a front surface of which it has at least one semiconductor light source, and
on its rear surface it has at least two exposed, continuous contacting conductor tracks,
wherein the at least one lighting unit (70) furthermore comprises a translucent housing element (73), which is designed such that it can be mechanically coupled to the mounting profile rail, and with which the lighting unit can be held in the mounting profile rail,
wherein the supply connector (50a, 50b, 50c) has contact devices for making an electrical coupling of the contacting conductor tracks of the lighting unit with those of a second lighting unit, and/or with a supply cable, and
wherein the supply connector (50a, 50b, 50c) furthermore comprises a housing element, which can be mechanically coupled to the mounting profile rail (60a, 60b, 60c) or to the at least one lighting unit (70), and with which the supply connector is retained in the mounting profile rail.
