ABSTRACT:
A mercury-vapor lamp is provided with a reservoir in which a superfluous amount of mercury is stored in the form of liquid state. The liquid mercury in the reservoir is cooled to a certain temperature. The pressure of mercury-vapor is automatically reduced to the saturated pressure of the liquid mercury cooled. In this configuration, the pressure of mercury-vapor is controlled by adjusting the temperature of the liquid mercury stored in the reservoir.
