A lamp assembly configured to inductively receive power from a primary coil.
The
inductively powered lamp assembly includes a lamp circuit including a secondary
and a lamp connected in series. In a first aspect, the lamp circuit includes a
capacitor connected in series with the lamp and the secondary to tune the circuit
to resonance. The capacitor is preferably selected to have a reactance that is
substantially equal to or slightly less than the reactance of the secondary and
the impedance of the lamp. In a second aspect, the inductively powered lamp assembly
includes a sealed transparent sleeve that entirely encloses the lamp circuit so
that the transparent sleeve is fully closed and unpenetrated. The transparent sleeve
is preferably the lamp sleeve itself, with the secondary, capacitor and any desired
starter mechanism disposed within its interior.
