Sealed, inductively powered lamp assembly

A lamp assembly comprising:

• a shell that defines a socket;
• a lamp housing assembly including a lamp housing dimensioned to fit in said socket and shaped to form an enclosure, and define an opening adjacent said shell and a light source disposed in said lamp housing;
• and
• a transformer comprising:
• a primary winding disposed in said socket and adapted for attachment to a power supply;
• a secondary winding disposed in said lamp housing and connected across said light source;
• and a ferrite core adjacent said primary winding, said ferrite core extending out of said socket through said opening and into said lamp housing enclosure, wherein said secondary winding is positioned in said lamp housing adjacent said lamp housing opening to at least partially surround a portion of said ferrite core that extends into said lamp housing enclosure.

A lamp assembly comprising:

• a shell that defines a socket, said shell being formed with an outwardly directed protrusion, and including a primary winding attached to said shell and disposed in said protrusion;
• and
• a lamp assembly including:
• a lamp housing forming an enclosure dimensioned to fit into said socket, said lamp housing further being formed with an inwardly directed boss that defines a space for receiving said shell protrusion;
• a light source disposed in said enclosure;
• and a secondary winding disposed in said enclosure and connected across said light source, said secondary winding being disposed around said boss so as to be located adjacent said primary winding.

A lamp assembly comprising:

• a socket formed from a shell including a primary winding attached to said shell and adapted for connection to a power source;
• and
• a lamp assembly including:
• a lamp housing forming an enclosure dimensioned to fit in said socket;
• a light source disposed in said enclosure;
• a printed wiring board secured in said lamp housing;
• and a secondary winding formed on said printed wiring board in said lamp enclosure, said secondary winding being positioned adjacent said primary winding.

A lamp assembly comprising:

• a socket assembly including:
• a shell;
• a printed wiring board secured to said shell;
• and a primary winding adapted for attachment to a power supply wherein said primary winding is formed on said printed wiring board;
• and
• a lamp assembly including:
• a lamp housing forming an enclosure and dimensioned to fit in said socket assembly;
• a light source disposed in said lamp housing enclosure;
• and a secondary winding disposed in said enclosure and connected across said light source, said secondary winding being positioned in said lamp housing so that, when said lamp assembly is disposed in said socket assembly, said secondary winding is adjacent said primary winding.

A socket for receiving a lamp assembly having a secondary winding contained therein, said socket including:

• a shell defining an exterior space to receive the lamp assembly;
• a printed wiring board secured to said shell, said printed wiring board being spaced away from said exterior space defined by said shell;
• and
• a primary winding formed on said printed wiring board wherein said primary winding is adapted for connection to a power supply and is located in said shell so that, when the lamp assembly is disposed in said exterior space, said primary winding is adjacent the secondary winding in the lamp housing.

A lamp assembly for installation in a socket having a primary winding, said lamp housing including:

• a back shell and lens secured together to form an enclosure, said enclosure dimensioned to fit into the socket;
• a light source disposed in said enclosure;
• a printed wiring board disposed in said enclosure;
• and
• a secondary winding formed on said printed wiring board and connected across said light source, wherein said secondary winding is positioned in said enclosure so that, when said lamp housing is disposed in said socket, said secondary winding is adjacent the primary winding.
