1. A light trunking system (1), comprising:
at least one trunking rail (6) for fastening components (7 . . . 13) of the light trunking system (1) to the trunking rail (6);
electrical lines (L3, L4) from a mains connection, which run in the trunking rail (6) and can be contacted by the components (7 . . . 13) in order to supply power to the components (7 . . . 13);
a data terminal (D1, D2) for receiving data; and
a first adapter (16), which is connected to the electrical lines (L3, L4) and to the data terminal and is designed to transmit data received by the data terminal (D1, D2) to a second adapter (17) via the electrical lines (L3, L4) by modulating the data signal received at the data terminal in the high-frequency range of 2 MHz to 68 MHz onto a mains voltage that is applied to the mains connection;
a component (13, 19) comprising:
means for fastening the component (13, 19) to the trunking rail (6),
means (21) for contacting the electrical lines (L3, L4), and
the second adapter (17, 22), which is connected to the electrical lines (L3, L4) and is designed to transmit data via the electrical lines (L3, L4) to the first adapter (16) by modulating data and/or to receive data transmitted via the electrical lines (L3, L4) by demodulating data.
