description A compact low-pressure mercury vapour discharge lamp comprises two or more straight tubes which are interconnected by arcuate connecting means (12) to form a discharge chamber between two electrodes (9). These electrodes are located in the distal ends (2,3) of the lamp, and the ends (2,3) are connected in a gas-tight manner to a lamp base (8) incorporating necessary contact pins (6, 7) and electrical conductors (8).The interconnecting means (12) presents a spine (13) which extends along the means (12). When seen in cross-section, the spine (13) exhibits an acute angle which defines a condensation space for condensation of mercury vapour used in the lamp. As a result of the shape of the spine (13) the mercury vapour condenses outside the circular cross-section area (14) where the positive column is formed during operation ofthe lamp, the discharge current passing in this column.
