摘要： The low-pressure discharge lamp is discolsed having a lamp vessel into which hollow cylindrical electrodes enter, between which a discharge path extends. At least one of the electrodes has a tube at a distance from an end thereof, the tube extending in the discharge path. The tube is connected to the electrode by electrically conductive means and is coated with electron emissive material. The surface area of the material of the means in cross-section is at most 25% of the surface area of the material of the electrode in cross-section.
