Abstract
Abstract An improved lamp construction and associated method of manufacture of a lamp that includes a sealed capsule with lead-in wires and a ceramic base. A pair of sleeves each defining a lamp contact pin at one end thereof are swaged at the other end thereof to the lead-in wires to secure the sleeves thereto. The ceramic base has a bottom wall with a pair of holes therein for receiving respective sleeves with the contact pin ends thereof depending from the base bottom wall and with the swaged ends thereof defining a limiting wall for positioning of the sleeves in proper relation relative to the ceramic base. The cement is disposed in the ceramic base and cured to secure the sleeves and lead-in wires in the ceramic base.
