Inductively powered apparatus
First Claim
1. An inductively powered light assembly comprising:
- a primary coil generating a magnetic field;
a lamp assembly including;
a light source;
a housing having a first light transparent portion that is at least partially light transparent and a second light transparent portion that is at least partially light transparent, said first light transparent portion having different light transparency characteristics from said second light transparent portion;
wherein said lamp assembly is mountable within said magnetic field in at least two distinct orientations.

Abstract
An inductive power supply system for providing power to one or more inductively powered devices. The system includes a mechanism for varying the physical distance or the respective orientation between the primary coil and secondary coil to control the amount of power supplied to the inductively powered device. In another aspect, the present invention is directed to an inductive power supply system having a primary coil and a receptacle disposed within the magnetic field generated by the primary coil. One or more inductively powered devices are placed randomly within the receptacle to receive power inductively from the primary coil. The power supply circuit includes circuitry for adjusting the power supplied to the primary coil to optimize operation based on the position and cumulative characteristics of the inductively powered device(s) disposed within the receptacle.
