MEJORAS EN BASE ROSCADA PARA LAMPARAS ELECTRICAS

摘要

A screw base for high intensity discharge lamps or for larger sizes of incandescent lamps utilizes a threaded aluminum shell coated with a thin film of polytetrafluoroethylene. The thin film is penetrated at points of maximum contact pressure with the socket to provide electrical continuity while effecting a low friction surface preventing galling and sticking of the base in the socket and permitting easy lamp insertion and removal.
