ABSTRACT:
A compact low pressure mercury vapor discharge lamp which utilizes an amalgam for reducing the vapor pressure of mercury by absorption. The lamp has a tubulation positioned at a location spaced from the lamp electrodes which is in communication with an arc sustaining gas and includes a container for retention of liquified amalgam within the tubulation. The mercury vapor from the electrical charge sustaining gas is in communication with the amalgam for absorption.
