An improved electrically conductive light bulb base for use with common threaded light bulb sockets currently widely used. The improvement combines a substantial reduction in the amount of thread required, by employing a shorter thread that enlarges or increases in size, in radius, or both. This type of thread is in place of the standard thread in securing the bulb in the socket. Optionally, short portions of thread may be provided on one side of a generally cylindrical, smooth base. The particular advantage is that the bulb inserted by hand can be inserted and secured or released and removed with a minimum number of turns of the wrist.

L'invention concerne un culot d'ampoule électroconducteur amélioré destiné à être utilisé avec des douilles d'ampoule filetées d'usage courant. L'amélioration consiste en une réduction sensible de la quantité requise du filetage, grâce à l'utilisation d'un filetage plus court dont la taille et/ou le rayon augmentent. Ce type de filetage remplace le filetage courant permettant de fixer l'ampoule dans la douille. Eventuellement, des parties courtes de filetage peuvent être disposées sur un côté de la paroi d'un culot généralement cylindrique et lisse. L'avantage particulier réside dans le fait que l'ampoule qui est fixée à la main peut être fixée ou enlevée avec un nombre réduit de rotations de poignet.
