Abstract
In a low-pressure gas discharge lamp provided with a gas discharge vessel comprising a gas filling with a discharge-maintaining composition comprising a) a molecular radiator compound, b) hydrogen as an additive and c) a buffer gas, which low-pressure gas discharge lamp is further provided with means for generating and maintaining a low-pressure gas discharge, the addition of hydrogen comes up with the following advantages: an increase of plasma efficiency and a decrease of the cold spot temperature at which optimum efficiency is achieved.
