Abstract

The invention relates particularly to a high-pressure sodium vapour discharge lamp having a discharge vessel 1 in which xenon and an absorbent are present. The xenon is partly absorbed in the absorbent. When the temperature is raised xenon is released. Both for starting the lamp and for the operating condition a suitable xenon pressure can be realised. According to the invention the absorbent 11 is housed in a cup 10 located in a cavity 35 in the wall of the discharge vessel 1. The absorbent 11 preferably comprises carbon, but may be one or more of fine-granular oxides, carbides, borides and metals. As shown, the cup 10, e.g. of niobium, fits tightly in cavity 35 and has cuts at its open side so that strips 10a are formed which are bent inwards to form a connection point to which the electrode rod 5a is affixed. A specific example is given. The invention may also be used in low pressure lamps. <IMAGE>
