| titleOfInvention | Discharge lamp |
| abstract | In a discharge lamp in which a cathode and an anode are opposed to each other inside an arc tube, even if an emitter other than thorium is added to the cathode, the emitter is prevented from being depleted early and the electron emission function is extended. The structure maintains the time and extends the flicker life of the lamp, and provides a structure excellent in the start-up performance at the time of initial lighting. A cathode 3 includes a main body 31 and a front end 32 joined to the front end thereof. The main body is made of a refractory metal material that does not contain thorium, and the front end includes an emitter ( In the sealed space 33 formed inside the main body portion and / or the tip portion, and higher than the emitter concentration contained in the tip portion. A sintered body 34 containing a concentration emitter (excluding thorium) is embedded, and the sintered body includes a rare earth composite oxide. [Selection] Figure 2 |
