Low pressure discharge lamp

摘要

The invention relates to a mercury-free low pressure discharge lamp with a discharge vessel having an ionizable filling. The surface temperature of the discharge vessel, and thus the temperature of the ionizable filling, can be adjusted at least in some sections such that an emitting substance can produce the radiation required for the excitation of the luminescent substance. The temperature of the fluid is preferably adjusted in a temperature control circuit, using a temperature sensor, a pump and a heating device.
