ABSTRACT:
An electrically insulative base for an incandescent lamp is disclosed having a three-part construction with all of the individual base parts being joined together in butt-seal engagement along a pair of horizontal planes parallel to each other and transverse to the longitudinal lamp axis. Said base construction is especially useful in the tungsten halogen cycle lamps of the high wattage type requiring that a ceramic material be used and whereby the ceramic base parts are joined together before lamp assembly with a ceramic sealing material.
