| titleOfInvention | High pressure metal halide lamp |
| abstract | The invention relates to a high pressure metal halide lamp comprising: a light transmitting discharge vessel enclosing a discharge space, sealed in a gas-tight manner, in which electrodes are disposed, which are connected to current conductors which extend to the exterior; a filling in the discharge vessel comprising a rare gas, a buffer gas and at least one transition metal halide chosen from the halides of hafnium, zirconium and tantalum. According to the invention each of the electrodes comprises an electrode part containing a carbide chosen from the carbides of hafnium, zirconium and tantalum. As a result diffusion of transition metal from the plasma into the electrode is strongly suppressed so that the lamp keeps very good colour rendering properties throughout its operation. |
