ABSTRACT:
An arc discharge lamp having an arc tube mounted within a lamp envelope includes a thermal switch for controlling application of electrical energy to a starting electrode. The thermal switch is mounted between the arc tube and the lamp base with its longitudinal axis generally parallel to the central axis of the lamp envelope. The thermal switch is spaced from the central axis of the lamp envelope by a support rod and extends into an annular space between the lamp stem and the wall of the lamp envelope. As a result, the maximum temperature of the thermal switch during lamp operation does not exceed about 400.degree. C.
