LOW-PRESSURE DISCHARGE LAMP

摘要

28-12-1978 1 PHN 9055 "Low-pressure discharge lamp". Low-pressure discharge lamp having a discharge space, limited by an elongate lamp vessel, electrodes at one end of the vessel in the discharge space between which electrodes a discharge takes place during operation of the lamp, the lamp vessel having partitions to divide the discharge space into chambers each extending substantially in the length of the discharge vessel which chambers communicate with one another via at least one opening which chambers are sequentially passed through by the discharge, the opening between at least two chambers being at least partly wedge-shaped, the minimum width being located nearest to an electrode whose discharge path extends itself after ignition.
