Abstract

Improvements introduced in a low pressure mercury vapor discharge lamp having an hermetic vacuum discharge tube and radiation transmitter having a nominal length comprised between 60 and 150 cm, an inner diameter of 20 to 28 mm, and which is designed to consume a nominal power of 0.25-0.50 watts per cm of length of the discharge tube during operation, which discharge tube comprises an amount of mercury, a quantity of rare gas and a luminescent layer which it comprises a luminescent aluminate having a hexagonal crystalline structure akin to the structure of the hexagonal ferrites.
