ABSTRACT:
A low-pressure mercury vapor discharge lamp. The lamp includes at least two tube sections substantially parallel to each other for holding a quantity of mercury vapor, sealings for sealing one end of each of two of the tube sections, discharge electrodes for activating the mercury vapor for generating a luminescent discharge, a reduced diameter connecting tube for sealing the remaining ends of the tube sections to one another in successive pairs, and an amalgam for maintaining the mercury vapor pressure at a level which maintains the luminance of the discharge at a substantially constant value.
