An electric lamp according to the invention is provided with a lamp vessel (20) which is sealed in a gastight manner and has a wall (21) of ceramic material, while at least one current supply conductor (31a,b) is connected to an electric element (30a,b) arranged in the lamp vessel (20) and issues to the exterior via a lead-through channel (23a,b) in the wall (21). The current supply conductor (31a,b) has a first part (32a,b) with a comparatively high and a second part (33a,b) with a comparatively low melting point, which parts form a welded joint (36a,b) with mutually facing ends (34a,b; 35a,b). The first part (32a,b) merges into a narrowing end (34a,b) having a length L and having a circumference O at the transition, which length L is at least one tenth of the circumference O, while the end (34a,b) is embedded at least partly in the end (35a,b) of the second part (33a,b). The electric lamp according to the invention has the advantage that the current supply conductors to be used therein can be manufactured more efficiently and with less wastage. |
