ABSTRACT:
An illumination system having a continuous fixed ceiling panel, at least one light source suspended by a telescoping arm from the panel and a split-core transformer formed by two electroinductive coils enclosed in permanent magnets through which a magnetic field is created for the sealed transfer of electrical energy through the panel to the light source. One magnet is disposed on opposite surfaces of the panel. Rollers or a pneumatic system may be disposed between each magnet and the surface of the panel on which the magnet is disposed for sliding the magnets over the surfaces of the panel while maintaining the transfer of electrical energy. Secondary lighting means may also be included.
