Title: TRACK LIGHTING SYSTEM, AND A TRACK ADAPTOR AND A TRACK RAIL OF THE SYSTEM
Abstract:
A lighting system which has adaptors fitted to the channel of a rail for receiving power. The rail has a sense conductor extending along the length of the channel, in the form of a set of discrete conductor elements and a biasing arrangement to urge the conductor elements together. The discrete conductor elements are separated by the head of an inserted adaptor thereby to interrupt the sense conductor by breaking a contact. The adaptor has a locator unit for identifying a location of the adaptor within the channel, comprising locator terminals for making electrical contact with the two sides of the broken contact of the sense conductor. The invention relates to the rail, the adaptor and the overall system.
