HIGH-PRESSURE DISCHARGE LAMP

摘要

The invention relates to a high-pressure discharge lamp provided with a discharge vessel made of glass which encloses a discharge space having an ionizable filling and an electrode. The discharge vessel is provided with a seal which encloses an Mo foil having knife edges and forms a feedthrough for an electric conductor to the electrode. At the location of the foil, the seal has a gastight sealed cavity and a first antenna on the outer side of the cavity. Preferably, a second antenna is placed at the neck where the seal is connected to the discharge vessel. This reduces both hot restrike voltage and hot restrike delay.
