Abstract
A lamp has a globe with an open rear portion encircled by a mounting collar. A removable base structure includes a base member with a cylindrical wall telescopically receiving the mounting collar therein, with pins on the collar latching in J-shaped slots on the base. A ceramic socket is received in a cup-shaped socket holder having an annular flange fixed to the base member. The holder has an aperture through which a replaceable bulb capsule can be received so that its wire terminal leads can be plugged directly into the socket. A wave spring is retained on the holder flange for engagement with a flange on the mounting collar to bias the assembly in its latched condition, with the socket holder and the bulb capsule extending into the globe through the open end thereof.
