A light source with a heatable filament (1) or an electrode, with the filament or the electrode being arranged in a bulb (2) or in a tube, is provided with an improved service life by the provision of a depot (3) with at least one chemical element that is also present in the filament or the electrode, and which is associated with the filament or the electrode such that the element is supplied to the filament or the electrode. Furthermore, a method is described for regenerating a light source with a heatable filament (1) or an electrode, with the filament or the electrode being arranged in a bulb (2) or in a tube. By the method, the depot (3) is associated in a first step to the filament or the electrode, with the depot comprising at least one chemical element that is also present in the filament or the electrode. Finally, the element is supplied to the filament or the electrode.
A light source comprising a heatable filament or an electrode, with the filament or the electrode being arranged in a bulb or a tube, and further comprising a depot which includes at least one chemical element, with the element being also present in the filament or the electrode, and with the depot arranged in the bulb or tube and in association with the filament or electrode such that the element can be supplied from the depot to the filament or the electrode.
The light source of claim i, wherein the element in the depot is present in a solid or liquid form, or in a gaseous or vaporous state.
A method for regenerating a light source having a heatable filament or an electrode, with the filament or the electrode being arranged in a bulb or a tube, the method comprising the steps of:
