Abstract

PURPOSE: To provide a mercury lamp of the type started by pre-heater, in which a by-pass wire is connected in parallel with a bimetal switch adapted for disconnecting a preheating circuit, to eliminate thermal reaction due to self-heating of bimetal and thus unstable operation of the lamp at the time of re-starting the same.
