An electroluminescent lamp (23) obtains electrical power from a secondary, self-contained wire or other coil (22). The self-contained coil is energized through mutual induction with a physically separated primary coil (21). The secondary coil (22) behaves like the secondary windings of a transformer. The primary coil (21) may be mounted into/onto a table, tablecloth, place mat or some other item. When the EL lamp (23) (with integral secondary coil (22)) is placed in close proximity to the primary coil (21), which is supplied with AC or pulsed DC, electrical energy is transferred from the primary coil (21) to the secondary coil (22). Thus, this system mimics an air gap transformer with the EL lamp (23) serving as a load on the secondary's output. The system powers an EL lamp (23) with no visible means of electrical connection. |
