摘要： A high intensity discharge lamp comprises an arc tube, which encloses an arc chamber. The arc chamber contains a gas fill and the arc tube is terminated by at least one sealed portion. The sealed portions enclose an electrode assembly. The electrode assembly comprises an electrode, a lead-in wire and an electrically conducting foil. The electrode extends into the arc chamber. The lead-in wire extends outward from the sealed portion for providing electric contact with a power supply. The electrically conducting foil connects the lead-in wire and the electrode and provides a sealed electric connection through a sealed portion of the arc tube. At least one of the electrodes is provided with surface irregularities in a region between the foil and the arc chamber in order to control shape and size of cracks in a seal wall surrounding the electrodes. In the method, an electrode of predetermined geometry and structure is provided with at least one artificial surface irregularity. Subsequently, an electrode assembly comprising said electrode, a seal foil and a lead-in wire is prepared. The electrode assembly is introduced into an arc chamber, the arc chamber is closed with a seal, and the electrode assembly is sealed therein, so that the irregularities of the electrode are formed in a region between the foil and the arc chamber. The electrodes may be provided with artificial surface irregularities also after preparing the electrode assembly.
