Electric lamp, base for use therewith and method of assembling same

A method of assembling a base on an electric lamp including a reflector, an electrically conductive ferrule located within a surface of said reflector and an electrically conductive lead-in conductor connected to said ferrule and extending within said reflector, said method comprising:

• locating an electrically insulating cap having an opening therein on said reflector and substantially about said ferrule;
• extending an electrical conductor within said cap through said opening and electrically connecting said electrical conductor to said ferrule;
• positioning barrier means within said cap through said opening to define with the walls of said cap an open chamber substantially about said ferrule;
• and
• locating sealing means within said opening of said cap to provide a seal therefor, said barrier means serving to prevent said sealing means from entering said open chamber during said locating of said sealing means.

An electric lamp comprising:

• a reflector;
• a cover secured to said reflector;
• a light source located within said reflector;
• at least one ferrule located within an external surface of said reflector;
• at least one lead-in conductor electrically connected to said ferrule and extending within said reflector to provide a path for electrical current to said light source;
• a base including an electrically insulative cap having an opening therein and located on said reflector substantially defining an open chamber about said ferrule, an electrical conductor extending within said opening of said cap and electrically connected to said ferrule, sealing means located within said opening of said cap for providing a seal therefor, barrier means separating said sealing means from said open chamber about said ferrule and said walls of said insulative cap including at least one aperture therein relative to said open chamber to enable heat generated by said electrically conductive ferrule to pass therethrough.

A base for an electric lamp including a reflector, an electrically conductive ferrule located within a surface of said reflector and an electrically conductive lead-in conductor connected to said ferrule and extending within said reflector, said base comprising:

• an electrically insulative cap having an opening therein and located on said reflector substantially about said ferrule;
• barrier means comprised of a fiber material located within said cap adjacent said ferrule, said barrier means and the walls of said cap defining an open chamber within said cap substantially about said ferrule;
• an electrical conductor extending within said opening of said cap and electrically connected to said ferrule;
• and
• sealing means located within said opening of said cap for providing a seal therefor, said barrier means separating said sealing means from said open chamber about said ferrule.

An electric lamp comprising:

• a reflector;
• a cover secured to said reflector;
• a light source located within said reflector;
• at least one ferrule located within an external surface of said reflector;
• at least one lead-in conductor electrically connected to said ferrule and extending within said reflector to provide a path for electrical current to said light source;
• and
• a base including an electrically insulative cap having an opening therein and located on said reflector substantially defining an open chamber about said ferrule, an electrical conductor extending within said opening of said cap and electrically connected to said ferrule, sealing means located within said opening of said cap for providing a seal therefor, and a fiber material barrier means separating said sealing means from said open chamber about said ferrule.
