Abstract: The invention relates to an electric lamp provided with a body which radiates light in the operational state of the lamp and which is enclosed with intervening space by an outer lamp envelope which is provided at one end with a stemtube with a pinch and which supports a lamp cap shell, through which pinch current lead-through conductors extend, each current lead through conductor being connected to a contact point of the lamp cap shell via an external conductor. According to the invention, each of the current lead-through conductors and the accompanying external conductors is provided with a moisture-repelling coating at least at the area of a mutual welded joint.

Abstract: A high-pressure gas discharge lamp having a discharge vessel of aluminium oxide or yttrium oxide. Disposed within the discharge vessel is an electrode which is connected to a vacuum tight led-out current supply conductor which consists mainly of borides from the group consisting of titanium boride and zirconium boride.

Abstract: A high-pressure gas discharge lamp having a discharge vessel provided with an aggressive gas filling, and electrodes between which the discharge takes place during operation. A hydrogen getter is placed within the discharge vessel and it consists of a getter material surrounded by a hydrogen-permeable wall. The getter material comprises at least a material of the group yttrium, lanthanum, the lanthanides and alloys of the said elements. The hydrogen permeable wall comprises at least one of the elements chromium, molybdenum, tungsten, tantalum, nickel and iron.
