ABSTRACT:
This invention provides an improved electric lamp with a self-mounting frame member for mounting a light source capsule within an outer envelope. The improvement lies in the lamp's inclusion of means for substantially preventing rotational movement of the frame member when the frame member is mounted and secured by a base member. Rotational movement preventing means is located about the outer envelope's neck portion and forms part of the frame member. Rotational movement preventing means includes a grooveless brim on the neck portion, a pair of grooves on the outer surface of the neck portion and a frame member with mounting means positioned about the brim and mated with the grooves of the neck portion.
